All Activity

forecasts are opinions if everyone's opinion was the same, this forum won't be worth reading

Glad to see some good snowstorm action for you guys down there early in the season. Usually it's us N guys that see all the action this time of year, except for some LES events.

Please show us why you say the vertical resolution on skewts published by professional forecasters is wrong. You can't just say that without proof.

One big difference too between this year (at this time) compared to the last several years is water temperatures off the coast aren't as warm. Maybe not a huge deal now, but if we keep getting these pushes of colder air, this could be something to help drive the baroclinic zone a bit farther south and east than we've seen lately. Maybe instead of seeing lows go bonkers inland in the southeast or mid-Atlantic that happens farther east either along or just off the coast.

It looks like GEFS is trying to loop back into 7/8 after its u-turn into 6. Hovmollers shows this as well.

Yesterday, I noted that the GEFS was trying to push an EPO+, but its forecast 500 mb pattern was profoundly different from any of the December WPO-/EPO+/AO-/PNA- clusters. That suggested that either the teleconnection idea was off or the pattern was off, rather than some novel outcome. Overnight and through today's 6z cycle, the GEFS has continued to evolve. It has added a WPO+ to its EPO+ idea and restored its earlier idea of a AO+. It has now joined the Canadian ensembles that keep the MJO out of Phase 8 through its forecast horizon. In short, its previously significant areas of "disconnect" have disappeared overnight. Its forecast pattern is now more consistent with what one would expect. For now, the GEFS is trying to build a credible milder alternative scenario for the pattern/temperature evolution in North America toward mid-December. The EPS has not shifted toward that emerging GEFS idea. Therefore, the baseline idea remains that the northern tier of the U.S. and most of Canada should remain cold toward and probably beyond mid-December. The Southeast could still turn warm despite some shots of colder air. Mid-December and beyond is still in the low-skill distant realm. The big story through the weekend will be the significant snowstorm that will affect parts of the Midwest and Great Lakes Region. As a result, Chicago, Detroit, Milwaukee, and Toronto remain on track to experience their snowiest fall in five or more years. As an appetizer, Detroit added 0.1" snowfall yesterday and Toronto picked up 1.2 cm (0.5") yesterday.

I’m still worried we’re gonna have a cool start to December with some occasional chilly rains and then have a toasty Christmas time period.

Based on ensemble guidance seen through 06z/28, a rapidly intensifying and fast moving coastal low will bring a variety of weather elements to the NYC subforum. Periods of moderate to heavy rain are expected coastal areas- preceded by a little snow-sleet near dawn Tuesday and to closeout the storm Tuesday evening, while a period of heavy snow-sleet seems likely for the interior, especially the I84 corridor. Gusty northerly winds to 45 MPH are possible for eastern Long Island in the early Wednesday morning departure. Due to the late development and rapid departure of the storm, the chance of coastal flooding is minimal. All ensembles including ECAI have significant precipitation. This may be Central Parks first measurable snow-sleet of the season, though temps at or just above freezing at sunrise Tuesday may preclude onset measurable in the city. Delays are anticipated over the interior hilly terrain with possible school closings or early dismissals along and north of I80, especially the I84 corridor from the Poconos across se NYS into CT. One attached graphic (WSSI-P) shows the potential for a minor impact event per the NWS inputs for the their 1AM Friday forecast.

Very active month. Some hits Some not. All we can ask for is the chances. Temps are there hopefully the tracks are good. Peeps should know their climo. Anything more than 4 inches here the next 15 days is a bonus

I’ve stated it multiple times. It’s mild in the boundary layer even as of now for you. Maybe you start as some paste, and end as snow, but that’s a tough look even for you. Latitude hurts. It’s not being a debbie, it’s putting on a forecaster hat and looking at reality. Maybe it goes back to the 12z run yesterday and changes things.

Early December can work like 2018/2017 but we need that cold entrenched or strong CAD which im just not seing.

Why can’t you be happy for the north?

See show us the deets. Back your statement up is all ask not some weak sardonic Masshole remark

Snow showers around here. Yesterday aftrn had a couple snow squalls that reduced vis to 1/4 mile or less really fast. They were brief. Nice to have some wx action for a change these past few days.

Well hey….next weekend would be nearing a 7th anniversary for a storm very near and dear to the hearts of all Foothill brethren.

Oh and WGAL posted on social media about Tuesday’s snowstorm.

Brrrr. 36 with 35 mph winds

They were trying to show that yesterday but reverted a bit. Not a great sign when the flow is srly at 925 ahead of a low. Would be nice to get the NW-N-NE-E deal as it approaches.

Well congrats on 12-16 then. Send pics.

We don't rejoice until seeing the landscape turn wintry white after the awful decade this has been, but I 1000% prefer tracking a tangible storm and imminent BN temp pattern over talking about long range potential. Remember it was just a few days ago some looked at the models and saw a warm first week of Dec. Can't take anything for granted. We gotta produce when the windows for action open.

Shocker. Models have been pretty inconsistent around 5-7 days, and then the real picture gets painted inside of 5 days. Best advice e for the winter is not to pin any hopes until we are in the 3-4 day range. Not expecting much here in the valley, maybe 1-2” then rain

Trying to decide while if this is butt hurt over the last several years... or trying some DIR reverse psych

Be patient, things will be different this year. That was in the past.

IF you're looking for early trends today on model guidance...if you want colder, the first ingredient is get that initial cold push on Monday stronger....if we can drive that -10C 850 line down toward the south coast 12z-18z Monday, then you are looking at a colder profile. But if it gets hung up in CNE, you're gonna see that marginal airmass issue quickly develop on the coastal plain.

Wut? I see isothermic dump showme your better vertical resolution 6 z Euro. Deets!!!
