.DISCUSSION...
Issued at 359 AM CDT Fri Apr 25 2025

Through Sunday: We remain in a regime somewhat reminiscent of an
active summertime pattern, with a tropical humid airmass and
diurnal convection augmented by mesoscale features which result in
some activity persisting into the night. This morning, a more
pronounced shortwave and MCV feature were sustaining shower and
thunderstorm activity across north LA and southeast AR. These
features appear likely to continue to be key players through the
day, forcing continued convection as they move eastward across the
region during the daytime, with daytime heating driving
additional development further south of the current activity.
Coverage should drop off fairly quickly this evening with the loss
of daytime heating and the disturbance shifting to our east.
Saturday looks a bit less active as shortwave ridging briefly
builds in, but scattered mostly diurnal convection is still
possible within the moist airmass. As one more upper disturbance
rolls across late Saturday into Sunday, we could again see
upstream convection work its way toward the area as soon as
Saturday night, with additional diurnal shower and storm coverage
during the day Sunday.

Over each of these days, deep layer flow will be marginal for
organized convection, but there could be enough instability to
overcome that and result in a few brief stronger storms. With
slower storm motions and PW surpassing 1.5" at times, localized
flooding cannot be ruled out either.

Monday through Thursday: Upper ridging will temporarily build in
early next week, finally resulting in a break in rain chances for
the most part. It will still be warm and somewhat humid, however.
High temperatures may approach 90F in some areas, which is still a
quite above average.

During the middle to latter portion of the week, upper troughing
will begin to expand into the central CONUS again, nudging a cold
front toward the Mid South once again and the upper level
disturbance track closer to our area. This will yield an increase
in potential for scattered showers and thunderstorms through the
end of the week. As the front nudges closer to the area, there
could be potential for somewhat more organized convection, moreso
over the northwestern portions of the area, in the Thursday
- Friday time frame. /DL/

.AVIATION...
(06Z TAFS)
Issued at 139 AM CDT Fri Apr 25 2025

VFR flight categories prevail, but some LIFR stratus & potential
IFR vsby/fog can`t be ruled out with high humidity & recent rains.
Timing of onset is between 25/08-15Z Friday before some
improvement to VFR flight categories. Rain showers & low probs of
storms (20-40%) will be a concern, onset earlier in northwest TAF
sites (GLH & GWO) between 29/12-15Z while later (29/16-20Z)
elsewhere. Light southwesterly winds will prevail through the
06Z TAF period. /DC/
