.NEAR TERM...
(Tonight)
Issued at 853 PM CDT Mon May 20 2024

High pressure remains layered across the mid/southern Atlantic
states this Mon evening, with current temp trends mainly in the
70s/near 70F. With a light return flow pattern in place, temps
into early Tue again look to remain seasonably warm, with lows
mainly in the lower/mid 70s, under mostly clear skies. Some light
fog is again possible in the more fog prone sheltered/valley
areas, but overall coverage should be fairly sparse.

.SHORT TERM...
(Tuesday through Thursday)
Issued at 202 PM CDT Mon May 20 2024

Dry weather will continue through much of the short term period as
high pressure to our east keeps lower humidity in place while also
reinforcing southerly flow as upper ridging builds to our west.
Daily highs will climb into the upper 80s to lower 90s through
Thursday, while overnight lows fall to the upper 60s to lower 70s.
Will definitely feel like summer and most locations will likely
reach 90 degrees for the first time this year either Tuesday or
Wednesday. A slow moving cold front will slowly approach the area
on Thursday, and will result in lower-end chances (20-40%) for
showers/storms (favoring northwest Alabama and southern middle
Tennessee) during the afternoon. Trends favor most of the area
remaining dry through Thursday afternoon, with highs once again in
the mid to upper 80s.

.LONG TERM...
(Thursday night through Sunday)
Issued at 134 AM CDT Mon May 20 2024

A mid/upper shortwave pivoting from the Ozarks into the Mid SOuth
will finally push the aforementioned front into portions of the
Tennessee Valley by late Thursday night into Friday and
subsequently bring medium to high (40-70%) chance for showers and
storms to the area. General view of the storm environment would
favor plenty of CAPE with sufficient shear to support at least a
few organized strong storms, with gusty winds and hail (along with
locally heavy downpours) being the main threats on Friday. We`ll
remain in a fairly active pattern through most of the upcoming
Memorial Day holiday weekend, with zonal low aloft allowing for
additional shortwaves to traverse the region. Subsequently,
medium chances (40-60%)for showers/storms will be present in the
forecast both Saturday and Sunday.

.AVIATION...

Light/var winds will also become south around 8-9kt late Tue
morning.
