Everyone managed rain on Election Day, no one had a lot. Amounts averaged .10-.25" across NE Fl. & .25-.50" for SE Ga. Still...it was the most widespread & "heaviest" rain since Oct. 14th. Cooler air will now dominate through early Fri. before a warming trend begins later Fri. & continues into early next week.
An overall pattern change is underway for the Lower 48. See the map below -- a flip-flop of sorts as the persistent upper level troughing over the Eastern U.S. shifts to the west as the anomalously strong upper high breaks down over/near the NW Atlantic. So the tendency for at least the next couple of weeks -- probably taking us to at least T'giving (early this year - Nov. 22) -- will be for upper level troughing over the western half of the U.S. while upper level ridging dominates the Eastern U.S. The upshot is cold weather in the Pacific NW, wet weather for parts of the SW U.S., Rockies, Plains & Midwest that will occasionally bleed into the Ohio Valley. The East & SE U.S. will have generally mild, dry weather with only a few quick shots of rain & a brief drop in temps.
As part of an ongoing joint project between UAHuntsville, NOAA and NASA, John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville, and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

Notes on data released Nov. 6, 2012:
The pause in the anticipated El Niño Pacific Ocean warming event — seen in the sea surface temperatures in the Pacific during the past two months — is now appearing in the tropical upper air, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville. The absent El Niño shows up in the relative temperatures of the world’s parts: While October 2012 was the second warmest October in the satellite record for the Southern Hemisphere and fourth warmest for the north, the tropics were scarcely warmer than normal for the month — only the 13th “warmest” October in the 34-year satellite record.
Compared to seasonal norms, the coldest area on the globe in October was south central Saskatchewan to the east of Saskatoon, which was 2.28 C (about 4.1 Fahrenheit) cooler than normal for the month. The warmest area was in the central Bering Sea, where temperatures averaged 3.95 C (about 7.1 degrees Fahrenheit) warmer than seasonal norms for October.
