.SHORT TERM...
(Tonight through Friday night)
Issued at 336 PM CDT Wed Mar 27 2024
Some light reflectivity showing up on area radars in association
with a weak shortwave working across the region this afternoon.
Area web cams and observations give reason to think that most, if
not all, of this activity is virga. Expect this moisture and the
increased cloud cover to continue to work east of the area through
the evening with skies clearing overnight.
High pressure becomes centered over the region tomorrow with weak
ridging aloft yielding clear skies, light northerly flow and
afternoon highs in the lower 70s. The high slides east of the
region Thursday night turning winds back out of the south Friday
allowing dewpoints to gradually climb back into the upper 50s by
Friday night.

.LONG TERM...
(Saturday through next Tuesday)
Issued at 336 PM CDT Wed Mar 27 2024
Saturday through Tuesday features a large and expansive H5 ridge
with an elongated SFC high across the GoM. This will allow for a
rather abrupt warmup into the weekend and early next week. Highs by
the weekend/early next week could climb into the middle/upper 80s
with light to moderate onshore flow.
While confidence is marginal at this time, odds are increasing that
a positively tilted trof swings through with a cold front sliding
across the region Tuesday into Wednesday. Thereafter, dry weather
returns.

Issued at 700 PM CDT Wed Mar 27 2024
Forecast soundings/time-height sections indicate minimal low-
level/boundary layer moisture thanks to a dry nrly flow, thus VFR
conditions are expected to continue through the period with just
some mid-level cloud cover ongoing til the approaching shortwave
clears the area. Winds will initially remain nrly, but turn
variable Thursday afternoon as the sfc high moves overhead.

Issued at 336 PM CDT Wed Mar 27 2024
Offshore flow will continue to relax tonight into tomorrow before
turning back onshore tomorrow night as high pressure departs to
the east. Light to moderate onshore flow will then continue until
the passage of a cold front mid next week.
