A nice Thanksgiving holiday, then rain and snow for the Tahoe basin…

Very pleasant weather will prevail for the Tahoe Basin through Thanksgiving Day, then a change is on the way.

Wednesday and Thanksgiving Day look pleasant and even a bit on the warm side with highs in the 50’s, even near 60 in Incline Village. Friday will be a few degrees cooler, but dry.

Then the first significant storm for the Sierras this winter season will move across the area. Beginning Saturday and Sunday the precipitation will begin as rain, then change to snow Sunday night and continue Monday. Snow could be heavy at times.

Computer forecast models suggest 1 to 2 inches water equivalent across the Tahoe Basin, so 6 inches to a foot of snow may be possible before it all ends.

Steady snow will change to snow showers on Tuesday.

Northwest and East to See Significant Rains

The cold weather that has been gripping much of the Eastern United States will move out over the next week, and a significant warm-up will occur. The warmer temperatures will also bring significant rainfall, particularly along the Gulf Coast, where 3+ inches may occur from the bayous of Louisiana to the panhandle of Florida.
Even more rain may fall in the Pacific Northwest, where storm systems are expected to drop 4+ inches of rain along a broad swath from Northern California to British Columbia.

Cold Weather Outbreak in the United States

An arctic air mass invaded the United States this week, dropping temperatures as much as 25-40° below normal, with subfreezing temperatures reaching as far south as the Gulf of Mexico. Denver in particular set 4 new records in 3 days, including the lowest high temperatures ever recorded for November 11th and 12th (16°F and 6°F, respectfully) and the lowest low temperatures for November 12th (-13°F) and November 13th (-14°F). Three feet of snow covered Michigan’s Upper Peninsula, with up to 18 inches in northern Wisconsin and more than 16 inches in central Minnesota. Such weather conditions are quite atypical this early in the season.

And as if this isn’t enough cold weather for fall, a second snowstorm has moved into the Pacific Northwest, and is projected to bring more snow from the coast to the Rockies, as well as the Great Plains. For the two-thirds of the country affected by this arctic blast, be sure to stay bundled!

More like Fall this week…rain next week?

It looks like this week will mark an end, for now, to the warmer Fall Weather.
Sweater weather is here.

The ridge of high pressure that gave us offshore wind flow, very warm temperatures,
and daytime humidities 5% to 10%, has broken down and is being replaced by a trough
of low pressure.

This is resulting in much cooler days, a bit warmer nights, and late night and
morning clouds. Humidities will be in the 90% to 100% range at night. Expect highs
in the 70’s lows in the 50’s most places west of the mountains.

Althought there could be a few mornings with light drizzle, this trough is not
expected to bring rain.

Forecasters are getting more excited about rain prospects next week. The weekend
will be warmer, then the stage is set for another storm system about the middle of
next week. This storm looks to be stronger, and may be able to tap some of the
subtroptical moisture. Stay tuned…
