Preliminary Outlook to December 18November 12th, 2012 at 4:26 pm by Chad Evans under Chad's WLFI Weather Blog
COLDEST NIGHT SINCE MARCH 10…………GRADUAL WARMING TRENDS FROM BELOW-NORMAL TO NORMAL TEMPERATURES TUESDAY-WEDNESDAY…………
Tonight will be the coldest night since March 10, when we dropped to 21 degrees at WLFI. However, for everyone, this will be the coldest night since then. Tomorrow will be bright, but cool with highs of 40-45 with west winds at 10 mph. After near 24 tomorrow night, Wednesday will reach 45-50 with some high cirrus/cirrocumulus & contrails arriving.
DRY, MILD TREND WITH SPLIT FLOW PATTERN…………
Trend is dry & pretty mild Wednesday-Thanksgiving. Next system will stay south of here & zonal, split flow pattern favors us being bathed in a dry, Pacific airmass with no Arctic or Canadian intrusions.
The wetter-than-normal weather in the Southeast & on the East Coast is the system late this week-next weekend & then a Nor’Easter around Thanksgiving from the Southeast to the Northeast. At that point, we will cool off from the 50s to the 40s.
FEW SHOWERS THANKSGIVING EVE………..NEED TO WATCH FOR NOR’EASTER FORMATION TO OUR NORTHEAST…………
A few scattered showers are possible here Thanksgiving Eve, but Thanksgiving still looks bright & 40-45 here. However, that Nor’Easter may create a domino-effect of airport delays in the nation.
PRETTY DRY & MILD UP TO EARLY DECEMBER…………
Up to November 27, the pattern appears tranquil & pretty dry around here. However, signs point towards a second Nor’Easter in the Northeast with wind, snow, wind, beach erosion & flooding.
For us, looks pretty dry & mild up to early December.
TURNING COLDER AFTER DECEMBER 4 WITH FIRST SNOWFALL EVENT CENTERED AROUND DECEMBER 10……….
HOWEVER, there are signs of a significant chunk of colder air arriving around December 4 or 5 with highs only near 30 & lows around 14.
This overall colder regime with highs in the 20s & 30s looks to hang on through December 12 with perhaps a very cold night or two around this time with lows near 7 after the first substantial snow of 1-4″ centered around December 10. Another snow may occur around December 14, per long range data from the U.S., Europe & Canada.
A significant storm may bring heavy snow & wind to the Plains December 15-16 with rain here & 40s & 50s, however. Storm looks deep with windy, rainy conditions for us that will melt away the snow.
