air mass across central Alabama. The northern portion of the rain
shield has decreased considerably early this afternoon as the main
energy and lift stays near the coast. Do bot foresee any northward
transport of the more unstable air mass through this evening, and
expect little if any thunderstorm activity across central Alabama.
There could still be some isolated storms later this evening and
overnight as the main forcing associated with the upstream trof
approaches the area. Radar imagery to the west of Alabama shows
mainly scattered shower activity. This activity will likely fill
in as the short wave trof tracks eastward, so will continue with 
high rain chances overnight. The cold front or wind shift should
reach the AL/MS state line near midnight and the I-65 corridor 
around 3 am. The back edge of the rain should be near the surface
front. Rainfall amounts have been trimmed back considerably based
on affects from the MCV and lack of upstream convective activity.


Monday through Sunday.

Models are in better agreement with faster progression of the
upper trough on Monday. Rain should come to an end before noon,
and a mild afternoon is expected with some breaks in the clouds.
An upstream shortwave will reinforce the cold advection regime on
Tuesday into Wednesday with afternoon temperatures in the upper 
50s to lower 60s in the North on Wednesday. 

A transition to warmer conditions is expected on Thursday and 
Friday as southerly flow develops in response to a large trough
forming in the western CONUS. Model spread is quite large on the 
timing of the next front sometime in the Friday night through 
Sunday timeframe. Our forecast leans more toward the slower and 
more consistent ECMWF with the highest rain chances centered on 
Saturday night.
