.SHORT TERM...
(Today through Sunday)
Issued at 205 AM CDT Fri Mar 29 2024

Surface high in place across the deep south this morning. Ridging
extends ne across eastern TN. Skies are clear with light winds.
Temperatures have dropped and range from the upper 30s south to
lower 40s north. Spreads are rather low so we could pick up on
some patchy frost especially across our south come sunrise. Will
need to add some patchy frost across our south with the upcoming
grids/zones issuance.

Today, look for that surface high to move eastward with the upper
level trough pulling eastward as well. This will equate to a
substantial warmup and those winds will swing around to the ssw.

The upper pattern will quickly morph toward a zonal regime with a
west to east frontal boundary camping out a good distance to our
north. A strong upper system will begin to dig across the western
U.S. by Sunday. This will prompt some upper ridging across our area
with temps getting warmer. At any rate that boundary should remain
locked up to our north.

For the near term temps, a definitive warming trend is upcoming.
We`ll get into the 70s the next 2 days. Then, we could see close to
80 degrees for Sunday. By that time, low temps will climb back into
the 50s.

.LONG TERM...
(Sunday Night through next Friday)
Issued at 205 AM CDT Fri Mar 29 2024

In the extended forecast, Monday looks innocent enough with the ul
ridge in place and the w-e boundary still to our north. This will
change though as some strong energy aloft will drop southward out of
Canada. That aforementioned frontal boundary will then quickly move
our way and through the area on Tuesday. Some good instability will
be in play during the day with showers and thunderstorms expected.
North-south frontal extension seems to be better organized to our
east on Wednesday as the ul energy catches up. At any rate, we are
outlooked on our Day 6 so this next Tuesday will be our next
severe weather threat.

Behind the boundary, latest models showing that stronger nearly
closed off upper low across the eastern U.S. This could bring
showers and much cooler temperatures for Wednesday. Although,
cluster data over the last few days is not all that consistent
with the upper low reaching that far south. Latest NBM data
showing only a slow cooling trend with our extended numbers and
this seems reasonable at this point.

For the extended temps, it will be quite warm initially with near
80 for highs and lows in the 60s. Cooler behind the Tuesday fropa.
We could see 30s again for lows next Wednesday night.
