.NEAR TERM /Now Through Thursday/...The near term will be dry
through the period with clear skies. Aloft, the trough located
over the southeast CONUS continues to track off to the east-
northwest through the period. Northwest flow aloft then settles
into the region as ridging begins building into the region behind
this feature through Thursday. At the surface, high pressure
builds into the area from the west, tracking east across the
region through Thursday. As a result, clear skies and light winds
are expected through the period. As the surface high moves east,
surface winds will shift from north-northeasterly today, to more
east-southeasterly by Thursday afternoon. 

For temperatures through the period, expect highs to range from
the upper 50s to around 60 degrees generally north of the Highway
84 corridor, with low 60s along and southeast of Highway 84. For 
tonight, temps will be quite chilly again with temps bottoming 
out. Expecting a majority of the area to get near or just below 
freezing outside of immediate coastal zones. Temps are expected to
generally range from 30-34 degrees over the inland areas, with 
upper 30s to low to mid 40s closer to the immediate coast. Some 
upper 20s might even creep into our far interior counties tonight.
The only other noteworthy item tonight is expecting patchy frost 
once again over much of the CWA. Heading into Thursday, our cold 
spell begins to come to a close and we begin the journey back to 
some anomalously warm weather. Currently, expecting highs on 
Thursday to reach the low to mid 60s for most locations. The main 
forecast challenge on Thursday will be dewpoints. This is due to 
our surface high shifting east of the area through Thursday 
afternoon. Generally expecting dewpoints to range from the upper 
20s to low 30s across most of the area given decent vertical 
mixing through the early afternoon. The only exception will be
areas across southeastern MS into far southwestern AL and the FL 
panhandle, where dewpoints are expected to remain a little higher 
(upper 30s) as moisture begins to advect back in across that area.
The forecast reflects this with dewpoints several degrees higher 
in those areas for Thursday. By late Thursday afternoon and 
through the end of the period, with the surface high shifting 
further east and flow shifting to more east-southeast across the 
rest of the region, expecting dewpoints to slowly rise across the 
CWA. Low to mid 40s are expected by the end of the period across 
southeastern MS into far southwestern AL and the FL panhandle, 
with mid to upper 30s expected elsewhere. JEH/88
