.NEAR TERM...
(Tonight)
Issued at 1255 PM CDT Wed Mar 27 2024

High clouds will continue to spread into parts of the area from
the SW this evening, as a deep upper trough axis continues to
translate eastward thru the Gulf South region. Otherwise, a
persistent north flow around 5-10 MPH will usher slightly cooler
air into the central TN Valley overnight, with lows falling more
into the upper 30s/near 40F for most spots. These winds should
offset the prob for any fog/frost formation, outside of wind
protected valleys where some patchy fog/frost are possible.

.SHORT TERM...
(Thursday through Friday night)
Issued at 1255 PM CDT Wed Mar 27 2024

High pressure out of the Plains states will continue to build into
much of the region for the remainder of the work week. Lingering
mid/high clouds should also diminish Thu morning, as the upper
trough pattern moves into the Atlantic states. A persistent NNW
wind will again result in afternoon highs Thu in the lower/mid
60s. The sfc high will then become more centered across the region
Thu night, with sfc winds diminishing and lows into early Fri
falling more into the mid/upper 30s. This may result in some areas
of frost early Fri, although the coverage is not enough to warrant
the prob for a Frost Advisory. The sfc high will begin to move
east later in the day Fri, as highs climb into the upper 60s/near
70F, under mostly sunny skies. A developing return flow pattern
will then translate into lows Fri night trending more in the upper
40s/near 50, as some cloud cover begins to spread back into the
area out of the WNW.

.LONG TERM...
(Saturday through Tuesday)
Issued at 340 AM CDT Wed Mar 27 2024

Upper ridging and surface high pressure will be the main theme
through the weekend. This will lead to mostly sunny skies and a
decent warming trend that may end with many areas possibly seeing
highs around 80 degrees on Easter Sunday. By the end of the
weekend, the surface high pressure will begin to push east as a
low pressure system develops over the central CONUS. This will
result in increased moisture and cloud cover into early next week.

Our next chance at rain is anticipated through early next week as
an upper level, positively-tilted trough begins to make its way
across the central CONUS. A series of shortwaves are shown to
ripple across the Southeast Monday into Tuesday as well. At the
surface, a low pressure system looks to lift northeast from
Oklahoma/Kansas over Michigan and the upper Ohio Valley, with a
trailing cold front slated to traverse the Southeast by early
Tuesday. Model solutions continue to differ significantly with
regards to the evolution and timing of this system at this point,
resulting in much uncertainty in the potential for severe weather.
However, low to medium (20-40%) chances of showers and storms are
forecast by Monday evening and increase to medium (50-60%) area-
wide on Tuesday. This system will be monitored over the coming
days and updates will be given as details become clearer and
models comes into better agreement.
