    just did my pear tree for the very same reason.  I want good fruit this summer.

    Pinching the flowers is so often overlooked by the home grower .  Fruit quality ,size, and brix will defiantly be vastly improved  . If your not frimillar with bagging your fruit on the tree to protect the fruits you should look that up also. CPA is one of the hardest places in the country to grow fruit, because apple country has introduced so many invasive insects, and disease into the area.   If you have fun with your trees you should graft on a few more variety's of pear scion . Your tree is most likely grafted to bartlett root stock if you bought it from a nursery , which I believe is also compatible with Asian pears. It's still not to late to graft this season, but time is running very short for grafts. Grafting is unbelievably easy. All you need is a razor blade, electrical tape and some candle wax  . I graft all my own apple trees on m27 rootstock using the simple Saddle graft . I use m27 because it grows ultra dwarf trees that top off at 6' max ,but as far as apple trees go budagovsky 9 is the standard apple rootstock here in Pa. , and what you see in most orchards because of its hardiness in or area, and manageable but productive size.  At some point you are going to have problems with disease, and insects at both the rhizosphere ,and phyllosphere if you have not already . I can point you in the right direction organic or systematic .

    GREAT pics man.  You have a good eye for the camera.

    I don't see cellular damage on a single flower, all looks great, In fact those trees have way to many flowers and will probably be mechanically or chemically pinched to increase fruit size and to prevent apples bumping into each other and bruising in the wind. That is a very nice orchard .

       ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SATURDAY ACROSS
       PARTS OF EASTERN OHIO...MUCH OF PENNSYLVANIA...SOUTHERN INTO CENTRAL
       NEW YORK STATE AND PARTS OF NORTHWESTERN NEW JERSEY...
    
       ...SUMMARY...
       Strong thunderstorms may develop and organize east of the lower
       Great Lakes into the Hudson Valley and northern Mid Atlantic region
       Saturday, accompanied by a risk for severe wind gusts.
    
       ...Synopsis...
       While another significant short wave trough begins to dig within the
       main branch of mid-latitude westerlies, near/offshore of the Pacific
       Northwest coast, downstream flow is forecast to become less
       amplified into and through a confluent regime to the east of the
       Canadian Prairies and U.S. Great Plains during this period.  To the
       south of a lingering vortex of Arctic origins (initially centered
       over southern Hudson Bay), models suggest that a vigorous short wave
       perturbation will dig to the southeast of James Bay and come in
       phase with an initially more substantive perturbation within this
       regime.  The consolidating mid-level troughing may shift across New
       England into the Canadian Maritimes by 12Z Sunday.
    
       Associated forcing for ascent is forecast to support strong
       secondary surface cyclogenesis across the St. Lawrence Valley
       vicinity, while an initial occluded low over lower Michigan weakens.
        A conglomerating trailing cold front appears likely to advance east
       of the Appalachians and offshore of much of the Atlantic Seaboard
       into the Gulf coast vicinity by the end of the period.
    
       A narrowing pre-frontal plume of higher precipitable water content
       may advect across much of New England and Mid Atlantic coastal areas
       by mid afternoon, and the southern Atlantic coast later in the day. 
       Within this regime, weak lapse rates and/or lingering convective
       cloud cover and precipitation may limit appreciable destabilization
       Saturday, particularly to the north of the southern Atlantic
       Seaboard.
    
       Strongest mid-level cooling and height falls are forecast to
       overspread the upper Ohio Valley/lower Great Lakes region through
       the northern Mid Atlantic and western New England by early Saturday
       evening.  This may provide the focus for the primary severe weather
       potential for this period.
    
       ...Lower Great Lakes into Hudson Valley/northern Mid Atlantic...
       Lower/mid-tropospheric subsidence/warming likely will be in the
       process of overspreading the upper Ohio Valley and lower Great Lakes
       region at 12Z Saturday, before nosing east-northeastward through the
       day.  This is expected to allow for appreciable surface heating and
       boundary-layer mixing to contribute to low-level destabilization
       prior to the arrival of the mid-level forcing for ascent and
       cooling, which is expected to provide support for low-topped
       thunderstorm development.  This may impact areas to the east and
       south of Lakes Erie and Ontario Saturday morning into midday, with
       convection possibly consolidating into an organizing convective
       system.  Given the shear and the strength of the mean flow (40-50+
       kt in the lowest 6 km), coupled with the steepening low-level lapse
       rates, activity may support severe wind gusts while spreading
       east-northeastward across southern New York and Pennsylvania through
       the afternoon, perhaps as far east as the Hudson Valley vicinity by
       early Saturday evening.  Farther east, in areas not impacted by the
       cool Atlantic marine layer, a gradually waning risk for strong wind
       gusts may continue into the evening hours.
    
       ...South Atlantic Seaboard...
       Strong deep-layer mean flow and shear will be at least conditionally
       supportive of organized severe weather potential on Saturday, given
       sufficient destabilization.  At least widely scattered strong to
       severe thunderstorm development still appears possible.  It remains
       unclear whether instability and mid/upper support will become
       sufficient for anything more widespread, but higher severe
       probabilities could still become more apparent and introduced in
       later outlooks for this period.

    I’ve talked since last weekend about tomorrow’s severe weather in the Midwest. What’s coming Tuesday for them as modeled is worse than 2011. That system will hit PA next Wednesday, where if timing is right would create strong storms here as it’ll hit our warm sector (highs next Wednesday might hit mid 70s in the LSV).

    Michael Traditional Chocolate Chip Cookies, 3 Ounce 100 per case.

  6. If I copied YouTubers forecasts word for word and then toted their forecasts as my own I sure as hell wouldn't ask for a cookie too. The April 2011 outbreak was a three day event that was  also talked about several days in advance and the wording was far more intimidating  than the spc has to this point. A big day next tuesday sure, but the only people I see comparing the potential to 2011 are youtube weenies. Unfortunately because of the way youtube works and pays it's the worst place to get accurate forecasts days in advance unless you want to think every storm is the next superstorm. I think YouTube really raised people's expectations this winter way too high and hyped storms to preposterous levels and it spread from there.

       As the western trough ejects on Day 6/Tuesday, potential significant
       severe thunderstorms will be possible far eastern OK toward
       southeast MO and vicinity. Rich boundary-layer moisture will be in
       place amid steep midlevel lapse rates courtesy of an EML advecting
       across the region from the Mexican Plateau. This will supply plenty
       of instability with stronger vertical shear accompanying the
       ejecting trough. There is some uncertainty among medium range
       guidance on the northern extent of better moisture return and hence
       severe potential. This is mostly driven by differences in surface
       low, dryline and warm front positions related to somewhat different
       ejection of the upper trough. However, guidance is in very good
       agreement with respect to the southern portion of the risk area.
       Supercells capable of all severe hazards, some potentially
       significant, will be possible. 

    In 2011 it was clear by day 6 that something historic was very possible at least according to Dr Greg Forbes and the spc.

    As long as the buds are still closed there fine .  They probably also spray with a anti transpirant when needed . Unlike weather I know my Ag and Aq shit pretty good, been living it all my life.

  8. Yikes!!!  Not looking good. I'm thinking someone will end up upgraded to high risk by Friday. Speaking of 2011, I'm staring to see a reminiscent early spring pattern.   If these systems can continue to bring good energy this far east so early in the spring I think it will tell us a lot storm wise as we move forward into warmer climo.  Day 7 is also showing potential for something big. Maybe the trade off for no snow will be some kick ass spring light shows.

       ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS EASTERN
       IOWA INTO NORTHWEST ILLINOIS...AND ACROSS NORTHEAST ARKANSAS...THE
       MISSOURI BOOTHEEL...EXTREME WESTERN KENTUCKY...WESTERN
       TENNESSEE...AND FAR NORTHWEST MISSISSIPPI...
    
       ...SUMMARY...
       Intense and widespread severe thunderstorms are expected Friday
       afternoon into the overnight hours across portions of the Middle
       Mississippi Valley and Mid-South vicinity, eastward to the Lower
       Ohio and Tennessee Valleys. Intense, damaging gusts and several
       tornadoes (some strong and long-track) are expected.
    
       ...A bi-modal regional outbreak of severe storms is expected on
       Friday from the Mid-Mississippi Valley into the Mid-South...
    
       ...Synopsis...
    
       An amplified large-scale upper trough will be oriented from the
       northern plains to the southern Rockies early Friday. The trough
       will continue to deepen as it shifts east toward the MS Valley by
       00z, and oriented from the upper Great Lakes to the TN Valley
       vicinity by Saturday morning. With time, a closed low is expected to
       develop over eastern SD/NE/IA and a 100+ kt 500 mb jet will
       overspread the Mid-MS/OH Valley region. Intense southwesterly
       low-level flow also will overspread the Mid-South through much of
       the Midwest, with an 850 mb jet around 65-80 kt forecast by late
       afternoon into the overnight hours.
    
       At the surface, a deepening low centered over eastern NE/western IA
       Friday morning will shift east across IA through the afternoon
       before lifting toward southern Ontario overnight. A trailing cold
       front will extend from the low into eastern KS/central
       OK/west-central TX at 12z, and shift east across much of the Midwest
       and Mid-South. Ahead of the eastward-advancing front, strong
       southerly flow will transport 60s F dewpoints northward. Near-60 F
       dewpoints are expected as far north as eastern IA into northern IL
       during the afternoon. The warm sector will become more
       narrow/pinched off with north and east extent toward the Ohio Valley
       during the evening/overnight hours. However, near 60 F dewpoints are
       still expected in a narrow corridor ahead of the surging cold front
       into far southern IN and central KY. Richer boundary-layer moisture
       will reside from the Mid-South into the Lower-MS/TN Valleys where
       low to mid 60s F dewpoints are forecast.
    
       ...Mid-Mississippi Valley Vicinity...
    
       The strongest forcing/DCVA will be located over northern portions of
       the Mid-MS Valley close to the surface low/triple point. The
       expectation is that rapid destabilization through the morning
       (1000-2000 J/kg SBCAPE) and arrival of stronger forcing by early
       afternoon will result in initial supercell development near the
       surface low. All severe hazards will be possible with these fast
       moving storms, including a couple of strong tornadoes, intense
       damaging gusts and large hail. Cellular activity should spread
       across eastern IA/northern MO and into northwest IL before tendency
       toward upscale growth into linear convection ensues with eastward
       extent as convection develops south and east ahead of the front from
       east-central MO into northern/central IL. Damaging gusts will become
       more prominent with linear convection, though QLCS tornadoes will
       also be possible. 
    
       Additional storms will likely form near/just north of the warm front
       and move into parts of far southeast MN and southern WI. This
       activity should remain elevated, posing a risk for large hail and
       strong gusts, though any cell rooting on the warm front will pose a
       tornado risk as well, though the better warm sector is expected to
       remain south of MN/WI. 
    
       ...Mid-South Vicinity...
    
       A concerning scenario appears to be developing across portions of
       the MO Bootheel, northeast AR, western TN/KY and far northwest MS
       vicinity during the afternoon/evening. At least mid-60s F dewpoints
       are expected beneath modest midlevel lapse rates. This will support
       1500-2000 J/kg MLCAPE amid intense vertical shear. Forecast
       soundings indicate 0-1 km SRH increasing to around 400 m2/s2 by
       early afternoon. Thunderstorms are expected to develop by early
       afternoon ahead of the cold front within a pre-frontal
       trough/low-level confluence zone. Storm motion near 50 kt with
       supercell wind profiles will support cells capable of significant
       and long-track tornadoes. With time, upscale growth into a QLCS is
       expected, and intense wind gusts will be possible in addition to
       mesovortex tornadoes.
    
       ...OH/TN Valley vicinity...
    
       Low-level moisture/instability will begin to wane with north and
       east extent into the nighttime hours. However forecast guidance has
       consistently shown a few hundred J/kg MLCAPE with little/no
       inhibition. Forecast guidance generally tends to under-forecast
       north/east extent of severe potential in strongly forced, intense
       shear system. As such, the ongoing outlook maintains a broad
       gradient from Enhanced to Slight risk across this region. Damaging
       gusts and a few QLCS tornadoes will be possible into the nighttime
       hours.

    I figured they needed run and I can guess many people do not. 

    I added the oil info because find that most run regular small engine oil in there snow blowers and wounder why it will only throw snow a few feet even with new scraper blades. If the viscosity is too low you can lose 20%-50% torque because all your compression can exit piston cylinder, and or valves. If viscosity is too high and its cold out it will be hard starting  and can damage gaskets. When it comes to snowblowers use exactly what the manual says. If it cant be found order it.

    I’m very familiar with graupel and have experienced it many times. This was 100% not graupel.  Temp dropped to low 50s while the heaviest stuff was falling. I just know I was watching translucent ice pellets bouncing off of numerous surfaces, and I fully acknowledge the various reports of hail in the area. Who knows ha. 

    I always appreciate your posts Mr. Snowman . I hope my post didn't come across as a lecture towards you. Just giving my own many experiences with graupel . I will be sure to post pics and vids in the future that will leave experienced meso hounds scratching their heads and questioning what and when is possible as far as graupel or some kind of rounded perlite looking ice pellet is concerned in my area.

  11. I don't know if anyone remembers the nocturnal storm that formed and collapsed over Hershey in 2011. It was a rouge storm on a clear night with by far the most powerful strokes of lightning I have ever seen in my life. Even here in New Cumberland the earth shook with every stroke. 2011 was the shit minus all the death and destruction

    I think this was the same system that produced the Joplin EF5 on the 22 if I remember correctly . Could be wrong about that but I defiantly remember a tornadic storm around this date. It was a weird cell in that it was very elongated and liner looking but it was one cell with two inflow notches . If I have the right storm it also produced several funnel clouds. I was working in Etters that day the bark was much worse than the bite out there.

  13.  Grauple is a lot more common then people think ,and absolutely happens in warmer environments than today  . I cant count the times I have seen it at the very beginning of rain events even if it only last 30 seconds, especially at night.  Not surprised at all here given the temps.I know for a fact It can happen in any season because I have seen it many times in every season.

    I wonder if it is good for a snowblower to not be used for several years (engine lube, etc..)

    Same as any other small engine, the gaskets can dry out and become damaged if its sits to long . If there is gas in it change it out and run it for a few mins twice a year. Its more important than other small engines to use the right oil in snowblowers. Because they will always be operated in low temps there is more gap clearance between piston and cylinder so you will lose alot of compression if the oil is wrong.

    I think what you will find over time is that there are no legit weather models for this area of the US at any range, just people that cant or don't want remember yesterday.

    I would be very wary of youtube weather forecasters . They need you to click and comeback and they know who to trigger that reaction in guys like us.

     Unfortunately making people think the next hecs is just right around the corner has become a profitable business for enough people and agency's now that the next hecs will always be 8-14 days out.

    Note: A severe weather area depicted in the Day 4-8 period indicates 15%, 30% or higher probability for severe thunderstorms within 25 miles of any point.
    PREDICTABILITY TOO LOW is used to indicate severe storms may be possible based on some model scenarios. However, the location or occurrence of severe storms are in doubt due to: 1) large differences in the deterministic model solutions, 2) large spread in the ensemble guidance, and/or 3) minimal run-to-run continuity.
    POTENTIAL TOO LOW means the threat for a regional area of organized severe storms appears unlikely (i.e., less than 15%) for the forecast day.

       ...SEVERE WEATHER OUTBREAK POSSIBLE ON D4/THU...
    
       ...DISCUSSION...
       ...Thursday/Day 4...
       A regional outbreak of severe weather appears increasingly likely
       Thursday afternoon and Thursday night including the potential for
       large hail, damaging winds, and tornadoes, some of which may be
       strong. Available guidance is in ample general agreement with the
       east/northeastward-ejection of an upper trough from the southern
       Rockies early Thursday to the Ozarks/ArkLaTex by late Thursday
       night. Owing to a stalling/decaying front early this week,
       respectable low-level moisture will exist across much of the Deep
       South in advance of this approaching upper-level system and its
       related intense deep-layer wind field. Current thinking is that this
       severe potential should steadily increase across central/eastern
       Texas and possibly southeast Oklahoma during the day. This risk
       should only increase/further organize into Thursday evening across
       the ArkLaTex/ArkLaMiss and Lower Mississippi Valley, and eventually
       the Tennessee Valley late Thursday night.
    
       ...Friday/Day 5...
       Severe-weather potential is expected to continue to Friday across
       the Southeast States including Georgia/north Florida and the
       Carolinas, and possibly as far north as parts of the Mid-Atlantic.
       This will be as the upper-level trough races northeastward from the
       Lower Mississippi Valley toward the Ohio Valley/Mid-Atlantic States.
       Very strong deep-layer winds will coincide with a modestly unstable
       warm sector ahead of a cold front and/or residual convection from
       Thursday night. Damaging winds and a few tornadoes could occur
       across the region.
