Tranquil conditions across the Tennessee Valley this evening with
high pressure to the north and east still the primary influence
of the weather across the region. Just to our south a passing
shortwave will generate some cloud cover which will create at
least partly cloudy conditions here (especially south of the
Tennessee River) overnight. Any light rain showers will remain
well to the south. Otherwise, expect a cool and comfortable night
with lows dropping into the mid to upper 50s in most locations.

(Thursday through Saturday)
Issued at 205 PM CDT Wed May 29 2024

Strong upper level ridging builds over the area through Thursday,
as a surface high over the Ohio Valley dominates the weather over
the eastern CONUS.

Models do show a disturbance moving from Lousiana into SW
Mississippi Thursday morning. However, most models have this
feature falling apart as it runs into moves further ESE. Do
believe locations SW of a line from near Cullman, AL to the Quad
Cities area will see some cloud cover impacting them as this
occurs, but not precipitation is expected. These clouds will
likely to help keep temperatures a tad cooler. It will still be
fairly cool even further northeast where clouds will not be as
prevalent. Highs on Thursday look to make it into the mid 70s to
lower 80s in most locations.

Upper level ridging briefly amplifies over the area Thursday night
into Friday afternoon. This should keep precipitation associated
with a stronger upper level trough axis over Mississippi through
then. Lows Thursday night should be similar. Highs on Friday
should warm up in response to the building ridging. Highs should
climb to between 81 and 86 degrees.

Friday night forcing from the eastern edge of the upper level
trough axis moves far enough east that isolated to scattered
showers and thunderstorms could impact portions of northern
Alabama. Shear and instability look too weak for anything but run
of the mill thunderstorm activity producing gusty winds, frequent
lighting, and heavy downpours.

The coverage of showers and thunderstorms should increase in
coverage Saturday into Saturday night, as the trough axis swings
through the Ohio Valley and a trailing trough axis produces this
activity over the area. Again, shear is very weak, but instability
may be a bit higher. Still, no severe storms are expected as this
time.

This trailing trough axis lingers over the area into early next
week, producing daily chances of additional shower and
thunderstorm activity.
