Weather Has No Issues On Last Weekend of ‘07

6:15am – Pre-dawn infrared sat image (right) shows moisture in the form of a dense cloud canopy being slung north into W. TN.  Regional radars are showing rain as far north as a Huntsville, AL – Meridian, MS line.  This moisture will be booted east out of the area today.  Otherwise, low temperatures are mainly in the 20s, following highs yesterday ranging from 40 at Union City to 48 at Lexington, Jackson and Savannah.

This last weekend of 2007 will close out with a mix of sun and clouds and tempeatures today around 50 or so.  Overnight, weak high pressure over the region will give us mainly clear skies and temperatures again going down into the upper 20s and low 30s.

 

Monday’s 6 PM weather map (left, click to enlarge) will show one front passing through the region.  This front could produce one or two isolated showers with its passage.  But up the road from that front…over Missouri… that is the Arctic front that will plow through Monday night.  I won’t rehash its passage as my thinking remains unchanged (see Saturday’s post for details).  I must add, however, since I didn’t hit it very hard in yesterday’s post, that winds will really become an issue on Tuesday.  At times winds will be sustained between 20-25 mph.  That will push daytime wind chill temperatures into the teens on Tuesday.  And once again, flurries will be flying especially Tuesday afternoon and Tuesday evening.  A dusting could even occur in some locales, north of I-40.  A good day to be by the fire watching football!

The warm up on the heels of this arctic punch will be just as dramatic as the cold air’s arrival.  It may bring some scattered showers in for next weekend, which is pretty typical during the winter in W. TN.
