.NEAR TERM...(Rest of tonight)
Issued at 904 PM CST Thu Mar 4 2021

We currently have clear skies across the region tonight. Main feature
to note is the low pressure system over the Texas Panhandle, which
will bring increasing high and some mid-level clouds overnight into
Friday morning. This as well as cooler, drier air moving in from the
north will mean we aren`t expecting any fog development across the
area overnight. Temperatures are expected to drop into the low-to-mid
30s across southern Middle TN and NE Alabama, while NW Alabama may
stay in the upper 30s to lower 40s.

.SHORT TERM...(Friday through Saturday)
Issued at 200 PM CST Thu Mar 4 2021

Most guidance continues keep the surface high moving further
southeast into Friday. This should keep moving the surface low to
the southeast and mostly cloudy conditions are expected Friday
afternoon and night, no precipitation is expected with such a dry
atmospheric column shown in guidance. Most of the precipitation with
this surface low should remain over Arkansas, Mississippi and into
the northern Gulf Coast states. It will be noticeably cooler on
Friday, with highs only climbing into the lower 50s to around 60
degrees (Based on some guidance, this may be a bit optimistic).

A larger area of high pressure builds back into the southeast Friday
night into Saturday, behind the departing area of low pressure as it
moves into the Florida peninsula. Cool nights look likely, as this
airmass originates from southern Canada. Not sure climo isn`t keeping
temperatures warmer than they will be in the end. As a result went
slightly below guidance Friday night into Saturday especially. Lows
in the lower to mid 30s and highs in the lower 50s seem reasonable
overall.

.LONG TERM...(Saturday night through Wednesday)
Issued at 200 PM CST Thu Mar 4 2021

This area of high pressure is slow to move eastward. Therefore, kept
lows a bit below guidance through Monday and highs climbing with
abundant sunshine from the 55 to 60 degree range on Sunday to the 60
to 65 degree range on Monday.

A true warmup is expected Tuesday through the reminder of next week,
as persistent return flow around the backside of the departing
surface high from the Gulf of Mexico sets up over the area. Expect
highs by Wednesday into Thursday to likely climb back into the mid
70s to maybe around 80 degrees again. Through this period, dry
weather will continue.
