A tranquil and record-warm Thanksgiving for much of the U.S.

Celebrations of the Thanksgiving holiday in the United States in 2012 were aided by some of the most tranquil travel weather ever seen on what is America's busiest travel week. Unusually warm and precipitation-free conditions prevailed over almost the entire nation on Wednesday and Thursday, with many locations in the Midwest reporting their warmest Thanksgiving Day on record. At least three cities set records for their warmest temperature ever recorded so late in the year: Valentine, Nebraska (76° on Wednesday); Rochester, Minnesota (70° on Wednesday); and Sault Ste. Marie, Michigan (65° on Thursday.) While the quiet weather was a boon for travelers, the lack of rain in the Midwest allowed the nation's worst drought since 1954 to expand; the U.S. Drought Monitor reported that the area of the contiguous U.S. covered by moderate or greater drought expanded by 1% to 60% this week. This reversed a seven-week trend of slowly decreasing drought that began on September 25 and extended until November 13, when the area covered by drought declined from 65% to 59%. The latest ten-day forecasts from the GFS and ECMWF models show much below average chances of precipitation across more 90% of the U.S., including the drought regions. These dry conditions will allow the drought to expand over the next two weeks, and potentially cover 65% of the contiguous U.S. again by mid-December. The next chance for significant rains in excess of one inch in the Midwest will not occur until December 2, at the earliest. The lack of rain will potentially cause serious trouble for barge traffic on the Mississippi River by December 10, when the river may fall below the level of -5 feet at St. Louis needed to allow barges to not scrape bottom.


Figure 1. This week's U.S. Drought Monitor shows 60% of the contiguous U.S. was in moderate or greater drought.


Figure 2. Predicted 8-day precipitation amounts from the 06Z (1 am EST) November 23, 2012 run of the GFS model. For the 8-day period ending on Saturday, December 1, only the Northwest Coast, Central Gulf Coast, and portions of the Tennessee Valley are predicted to receive rains in excess of one inch.

Quiet in the Atlantic
There are no threat areas in the Atlantic to discuss today, and none of the reliable models is forecasting tropical cyclone development between now and the Friday, November 30 official end of hurricane season. I wouldn't dismiss the possibility of one more named storm forming in December in the middle Atlantic between Bermuda and Puerto Rico, but late-season storms forming in that location rarely affect land.

Have a great holiday weekend, everyone!

Fog is just a cloud. That's not severe weather. However, the effects of fog can be severe, so it gets warnings issued when it becomes dense, as it should.

90W in the West Pacific:



The GFS suggests this system will break an extended slow stretch out there by becoming a powerful typhoon, but the Euro doesn't even hint at developing it so I'm not real sure what to make of it. Clearly one of those two models is about to be badly embarrassed.

The holiday weather has definitely been remarkably lacking in weather-related drama. In fact, the entire work/travel week has been nice, with record highs over the last four days outnumbering record lows by 248 to 4, a 62:1 ratio)

Well, dense fog is hardly severe weather. In fact, fog is a stable-weather phenomenon. And that wreck, bad as it was, was in but a single location in Texas--hardly indicative of the nation's delightful Thanksgiving weather as a whole, and nothing on a par with, say, a massive multi-state winter system inconveniencing tens of millions. (Too, there are about 17,000 motor vehicle accidents in the U.S each day; the Texas wreck just happened to involve far more motor vehicles than normal.)

At any rate, I was merely echoing Dr. Masters' statement that "unusually warm and precipitation-free conditions prevailed over almost the entire nation on Wednesday and Thursday." I'm not sure how a a one-week cold snap nearly two months ago disproves his statement, or mine.

I'm surprised Central Florida isn't back in d0 drought yet, because we are abnormally dry. The once swelled ponds and drain ditches from the typical very rainy summer are now extremely low on water, and grass plants are completely brown, my backyard has turned to sand. We have only had about 0.20 over the last month. Which is about 15 times below what it should be.


Running almost 10" below average here for Sept/Oct/Nov and the cumulative average for those 3 months is 13.85" .19" and holding for November precip.

Technically, quite true. However, find yourself suddenly encompassed within this "hardly severe weather" phenomenon, realizing you're in an extremely life-threatening situation and you might discover identical moments of helplessness, anxiety and total fear for your life just the same if it were a severe tstorm, tornado, hurricane, blizzard, earthquake or tsunami...

The Pipe Nebula
Image Credit & Copyright: Yuri Beletsky (Las Campanas Observatory, Carnegie Institution for Science)

Explanation: East of Antares, dark markings sprawl through crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E. Barnard, the obscuring interstellar dust clouds include B59, B72, B77 and B78, seen in silhouette against the starry background. Here, their combined shape suggests a pipe stem and bowl, and so the dark nebula's popular name is the Pipe Nebula. The deep and expansive view was represents nearly 24 hours of exposure time recorded in very dark skies of the Chilean Atacama desert. It covers a full 10 by 10 degree field in the pronounceable constellation Ophiuchus. The Pipe Nebula is part of the Ophiuchus dark cloud complex located at a distance of about 450 light-years. Dense cores of gas and dust within the Pipe Nebula are collapsing to form stars.

Yeah I like how everything is color coated by height. Makes it easier to see what will be affected by the different steering layers.
