Added CPC's Oct 16 outlook. 

Hard to believe no place in the country is forecasted to  have below normal temps

[donsutherland1]

[wdrag]

Still overall AOB normal first 10 days... and models are "attempting" first flakes mix for I84 high terrain, esp 11/8-9. Nothing unusual. 

[wdrag]

Added the monthly outlook update from Oct 31 to the topic.  Canadian block gone now for at least a couple weeks so maybe the extreme potential down here is reduced til later Nov?  Fast flow USA/Candian border suggesting frequent gusty CFP's next 10 days.   Attached snowfall in Old Forge NY this Nov 1 morning, just to whet your CP appetite. I hope we get more than a half inch this winter in the park.

55 / 38 mostly clear and still breezy.   Looking mainly dry as the euro lost the 3rd/4th system and warmer overall through the next week.  Need to watch between the 8 - 11 for the next cutoff / system to bring next round of rains.  Widespread freezes will look to evade the area the next 7 days at least.

Historical:

1846: 87 pioneers were trapped by early snows in the Sierra Nevada that piled up to 5 feet deep with 30 to 40 foot drifts. Only 47 survivors lived to tell of the 'Donner Pass Tragedy'. (Ref. Wilson Wx. History)
 

 

1848: When Joseph Henry came to the Smithsonian, one of his priorities was to set up a meteorological program. In 1847, while outlining his plan for the new institution, Henry called for "a system of extended meteorological observations for solving American storms." On November 1st, 1848, Joseph Henry and Navy meteorologist James Espy wrote a letter urging anyone interested in becoming a weather observer to signify their willingness to do so. By 1849, he had budgeted $1,000 for the Smithsonian meteorological project and established a network of some 150 volunteer weather observers. A decade later, the project had more than 600 volunteer observers, including people in Canada, Mexico, Latin America, and the Caribbean. Its cost in 1860 was $4,400, or thirty percent of the Smithsonian's research and publication budget. 

1861 - A hurricane near Cape Hatteras, NC, battered a Union fleet of ships attacking Carolina ports, and produced high tides and high winds in New York State and New England. (David Ludlum)

 

1870: United States Army Signal Corps observers at 24 sites around the country simultaneously made weather reports and transmitted them to Washington, where a national weather map would be drawn. These simultaneous reports also started the process of sending out weather reports by telegraph to metropolitan newspapers. This would be the beginning of our present-day National Weather Service.

 

1950: The highest temperature ever recorded in Richmond, VA in November was 86 °F that occurred on three dates. Two of these dates on November 1st in 1950 and 1974.
(Ref. Richmond Weather Records KRIC )  Strong high pressure across the southeast ridged from the southern Plains to the Great Lakes and East Coast bringing record highs. Locations reporting all-time November record highs included: Baltimore, MD: 86°,  Newark, NJ  85 ; Philadelphia, PA: 84°, New York (Central Park), NY: 84°, Allentown, PA: 81°. Other daily record highs included: Richmond, VA: 86°, Charleston, SC: 85°, Norfolk, VA: 85°, Washington, DC: 85°, Wilmington, DE: 85°, Charlotte, NC: 84°, Asheville, NC: 83°, Lynchburg, VA: 83°, Roanoke, VA: 83°, Chicago, IL: 81°, Atlanta, GA: 81°, Pittsburgh, PA: 80°, Dayton, OH: 79°, Bristol, TN: 79°, -Tied, Elkins, WV: 77°-Tied, Buffalo, NY: 76°. (Ref. Wilson Wx. History)

1966 - Santa Anna winds fanned fires, and brought record November heat to parts of coastal California. November records included 86 degrees at San Francisco, 97 degrees at San Diego, and 101 degrees at the International airport in Los Angeles. Fires claimed the lives of at least sixteen firefighters. (The Weather Channel)

1968 - A tornado touched down west of Winslow, AZ, but did little damage in an uninhabited area. (The Weather Channel)

1974: The highest temperature ever recorded in Richmond, VA in November was 86 °F that occurred on three dates. Two of these dates on November 1st in 1974 and 1950. (Ref. Richmond Weather Records KRIC )

1982: This date began a five day heat wave across much of the east as high pressure anchored off the Carolina coast bringing a south to southwesterly flow. Record highs for the date included: Corpus Christi, TX: 88°-Tied, Meridian, MS: 86°, Sterling (Dulles Airport), VA: 84°, Huntsville, AL: 83°-Tied, Cincinnati, OH: 80°, Wallops Island, VA: 79°, New York (Kennedy Airport), NY: 77°, Milton, MA: 74°-Tied and Worcester, MA: 72°. (Ref. Wilson Wx. History)

1987 - Early morning thunderstorms in central Arizona produced hail an inch in diameter at Williams and Gila Bend, and drenched Payson with 1.86 inches of rain. Hannagan Meadows AZ, meanwhile, was blanketed with three inches of snow. Unseasonably warm weather prevailed across the Ohio Valley. Afternoon highs of 76 degrees at Beckley WV, 77 degrees at Bluefield WV, and 83 degrees at Lexington KY were records for the month of November. (Storm Data) (The National Weather Summary)

1988 - Low pressure brought gales and locally heavy rain to the northeastern U.S. The rainfall total of 1.46 inches at Newark NJ was a record for the date. New York City was soaked with more than two inches of rain. (The National Weather Summary) (Storm Data)

1989 - A strong cold front ushered snow and arctic air into the north central U.S. Snow whitened North Dakota and the Central High Plains Region. Up to five inches of snow blanketed Denver CO. Yellowstone Park WY was the cold spot in the nation with a morning low of 4 degrees below zero. (The National Weather Summary) (Storm Data)

1991: The great ocean storm that had battered the East Coast of the U.S. for the past 2 days underwent a remarkable transformation. Convection grew and wrapped tightly around the center and on satellite imagery an eye formed. An Air Force reckon plane found a rather small but intense circulation near 39.5N/66.5W with a central pressure of 981 millibars or 28.97 inches mercury and sustained winds of 75 mph. Just a couple of days before, the large extratropical cyclone which contained former Hurricane Grace created havoc along the east coast. This type of evolution from a large extratropical low pressure to a small hurricane is rare but not unprecedented. The storm was never named, but it was the basis for the book and movie “The Perfect Storm”. (Ref. Wilson Wx. History) (Ref. AccWeather Weather History)

1993: A series of low pressure areas associated with the deep upper level trough which had been responsible for the record cold across the southern and central U.S. Over the past few days dumped big early season snows over the Ohio Valley and the Northeast. 3-day totals included 19.5 inches at Ellenburg Depot, NY, 19 inches at Mount Mansfield, VT and Sabinsville, PA, and 18.5 inches at Stillwater Reservoir, NY. The 10.3 inches that fell at Mansfield, OH and 9 inches at Burlington, VT were the greatest snowfalls ever for so early in the season. (Ref. Wilson Wx. History) (Ref. AccWeather Weather History)

2000: As road crews cleared snow from highways in western North Dakota, at least 3 tornadoes touched down 125 miles away in Bismarck, ND. The F1 twisters struck without warning in the early afternoon damaging 42 homes. Tornado watches and winter storm warnings were in effect for some locations in the Dakotas at the same time on this unusual weather day. 31.9 inches of snow fell at Lead, SD to establish a new 1-day snowfall record for November. (Ref. Wilson Wx. History)   heavy and persistent rains across the eastern half or the windward side of the "Big Island" of Hawaii dumped 27.24 inches of rain at the Hilo Airport in 24-hours, breaking the previous 24-hour rainfall record.
(Ref. Wilson Wx. History)

2014: Interstate 40 has reopened along the Tennessee-North Carolina state line after being closed due to weather conditions earlier today. 22 inches of snow have been recorded at Mount LeConte, 15 at Newfound Gap and 12 in Hartford,TN in an early season snowstorm. A hiker has been seriously injured by a falling tree in the Greenbrier area of the Great Smoky Mountain National Park as a winter storm dumped heavy snow in the mountains. The park service said it would take some time to evacuate the "seriously injured" hiker due to weather conditions. (Ref.News Sentinel staff 7:23 AM, Nov 1, 2014)

2014: Up to 6 inches of snow fell in Gilbert, South Carolina.

I hope we get more than a half inch this winter in the park. 

 

Sadly Walt, my inner city UHI coastal plain location may not even see this until we are comfortably into meteorological winter. Even so we will still rejoice when we do. Stay well, as always ….

Old Forge-5 hour drive away but may as well be 5 light years in terms of snow.

Highs will reach the middle and upper 50s in much of the region tomorrow. It will then turn slightly milder with highs in the upper 50s and lower 60s through the middle of next week.

A weak cold front could cross the region after midweek, perhaps touching off a few scattered showers. Highs will then fall back to the lower and middle 50s. 

In the long-range, the guidance suggests that an AO+/NAO+ regime could develop during the first week of the month. As has often happened with the loss of strong blocking, a milder regime could develop shortly afterward. 

The ENSO Region 1+2 anomaly was +0.3°C and the Region 3.4 anomaly was -0.6°C for the week centered around October 22. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.07°C and the ENSO Region 3.4 anomaly has averaged -0.48°C. La Niña conditions will likely continue through mid-winter.

The SOI was +5.79 today. 

The preliminary Arctic Oscillation (AO) was -0.149 today. The NAO was -1.008.

[uofmiami]

33.8 for Muttontown & 35.1 for Syosset this morning. 

[Brian5671]

Frosty morning here

[FPizz]

30.9

[Sundog]

My Ambient Weather Station tends to shoot up once the Sun is hitting it in the morning. It will reach a daily high in line with everyone else and then reach a low similar to other stations, but in the morning once the Sun hits it, it's always several degrees warmer than other locations. 

Isn't it supposed to be in the Sun? I don't get why mine gets so warm so quick because of Sun when others don't. 

[SACRUS]

49 / 40 off a low of 31 here.   Standard time for the next 127 days and we'll see if these time change bills flail or any have legs come this spring. Low to mid 60s in the warmest spots.  Clouds tomorrow / warmest is Tue/Wed where the warmest spots could make a run at 70.  Looks like an above normal / dry week with the next shot of rain next weekend.   Trough between the 9th and 11/12 before warming again towards mid month.

Did you try a radiation shield? I know that Ambient sells separate radiation shields for their sensors. The more expensive stations like Davis have a fan aspirated shield.

I have the same issue with my ambient.  In the afternoon, the radiation shield has the suns shadow cast over it by the weather station itself. But in the early mornings and late afternoons, the sun is shining on the radiation shield head-on, so you see a temp spike. 

[psv88]

The Davis doesn’t really have a problem like that. Its built in radiation shield is very effective.
