.SHORT TERM...
(Tonight through Monday night)
Issued at 1255 PM CDT Sun Apr 5 2026

Current radar imagery shows showers are ongoing across the area.
However when looking at actual observations not much is really
accumulating meaning most activity is not reaching the ground and
it`s likely the radar is picking up heavier signals showing up at
higher elevations. That being said expect these very light
showers/drizzle to continue moving eastward across the area. At the
same time drier air located over north TX is starting to make its
way southward. PWATs reflect this with only 0.4 to 0.6in to the
north while the more moist air (PWATs >1 inch) remain across the
southern two thirds of our area. We are starting to see this dry air
undercut the showers that have made it into the Hill Country with a
notable decrease in intensity over the last couple of hours. All
that being said most of this activity across the Hill Country and
along and south of I-10 should decrease in coverage moving
completely out of the area as the trough axis responsible moves off
to the east. Most areas should be dry come Monday morning.

For tonight expect another cool night as temps drop into the upper
40s north to lower 50s south. Monday will be just a few degrees
warmer with most areas breaking into the low 70s as clouds begin to
dissipate by the afternoon hours. This should lead to another rather
chilly night with lows dropping into the 40s north and low 50s south
as we remain in weak northeasterly flow.

.LONG TERM...
(Tuesday through next Sunday)
Issued at 1255 PM CDT Sun Apr 5 2026

A somewhat warmer day is in store Tuesday with highs reaching the
low to mid 70s. It looks like we stay in easterly-northeasterly flow
until Wednesday as low pressure across the plains and upper level
ridging help to keep westerly/northwesterly flow locked in place
aloft thus limiting a possible rapid warmup over our area. Global
Models continue to indicate a low forming over the Baja peninsula
mid week and then moving across Mexico and into West Texas either
Thursday or Friday. Moisture at the surface looks fairly limited
however there`s enough vorticity and mid-level moisture to wring out
a few showers and perhaps isolated thunderstorms. Otherwise expect a
return to more seasonable temps as southerly low level flow finally
returns with highs in the upper 70s/low 80s and lows in the 60s
Looking ahead, medium range guidance is hinting at a much more
powerful storm system that may move over Texas next weekend.
However, confidence remains low as models continue to struggle
with the evolution of the large scale pattern across the CONUS
beyond Wednesday of next week. It does look likely that our active
pattern continues which is great news cause many areas could
really use the rain to help put a dent in the ongoing drought.
