.NEAR TERM...
(Today)
Issued at 237 AM CDT Wed May 1 2024

Early morning satellite imagery shows patchy dense fog is
developing in and along the river valleys of northeast AL and
southern middle TN. Coverage is not high enough to warrant a Dense
Fog Advisory at this time, but will keep an eye on observations in
case one is needed through the morning commute hours. Otherwise,
an non-impactful day is on tap over the region as high pressure
keeps a dry and warm airmass in place. Expect mostly sunny skies
and light winds as afternoon temperatures rise into the low to mid
80s. Enjoy this early May weather!

.SHORT TERM...
(Tonight through Friday night)
Issued at 237 AM CDT Wed May 1 2024

High pressure will help keep things dry through much of the work
week. Highs will reach the upper 80s Thursday afternoon, and
possibly even near the 90 degree mark in a few locations. The
upper ridge will become slightly less amplified toward the later
half of the week, and several weaker shortwaves will traverse
along increasingly zonal flow. This coupled with a warm and moist
airmass will bring increasing clouds Thursday afternoon and a
return for rain/storm chances Thursday night through Friday. The
best chances (50-70%) for showers and storms will come Friday
afternoon and night, so be sure to pack an umbrella and check the
forecast before heading outdoors Friday. Friday will be noticeably
cooler with highs in the upper 70s/lower 80s.

.LONG TERM...
(Saturday night through Tuesday)
Issued at 237 AM CDT Wed May 1 2024

Scattered/numerous showers/tstms look to continue into the first
half of the weekend period, as a weak frontal boundary drifts SE into
the mid TN Valley and stalls. Weak zonal flow aloft coupled with
minimal low-level convergence should offset the prob for
organized/stronger tstms, although brief heavy rainfall cannot be
ruled out. Rainfall will then diminish during the second half of the
weekend, as the front weakens invof the area. Seasonably warm temps
look to continue thru the weekend period, with highs Sat/Sun
remaining predom in the lower/mid 80s, while lows into early Mon
trend in the lower/mid 60s. Scattered showers/tstms are then expected
on Mon, as the weak sfc boundary lifts back to the north as a warm
front. Once again, overall synoptic forcing looks fairly weak
although locally heavy rainfall is possible with a few of these
showers/tstms. Rain chances will then diminish once again Mon
night/Tue, as weak upper ridging moves across the region and high
pressure at the sfc becomes established over the eastern Gulf region.
Little change is also expected with overall temps into the new work
week, with highs Mon/Tue once again in the lower/mid 80s and
overnight lows remaining in the lower/mid 60s.

Patchy fog may continue to cause MVFR vsbys at KMSL through 14z,
otherwise no significant aviation impacts are expected as clear
