.SHORT TERM...
(Today through Tuesday)
Issued at 156 AM CDT Mon Apr 22 2024

Surface high pressure has built into our area overnight leading to
cool, well below normal low temperatures this morning. A weak mid
level impulse will pass to our south today keeping any rain away
from our area, however an increase in mid level clouds is expected.
Although, surface high pressure moves off to the east allowing
southerly lower level flow to return, the above mentioned clouds
will keep high temperatures well below normal after the cool start.
The southerly lower level flow brings low clouds tonight, that will
only slowly mix out on Tuesday. A warming trend begins tonight into
Tuesday, although temperatures remain slightly below normal.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 156 AM CDT Mon Apr 22 2024

Dry weather is expected for Wednesday across South-Central Texas as
weak upper ridging will be in place across the region. Southerly
winds will be near 10-15 mph with temperatures maxing out in the 80s
to near 90 degrees. Most of the area will remain dry on Thursday,
but some changes will be noted as the next trough axis moves into
the Central Plains. Lows Thursday will be in the 60s to near 70 with
highs once again in the 80s to near 90. A weak axis of lift will
trail the parent trough into Friday with another trough passing
through the Central Plains this weekend. This will allow for low-
level southerly flow to increase which should lead to breezy
conditions Thursday through the weekend with sustained speeds in the
10-20 mph range through this period. Higher gusts can be expected as
850mb winds approach 50 knots at times through the weekend. This
increase in southerly flow will also allow for dewpoints and low-
level clouds to increase. This will lead to low temperatures Friday
through Sunday to be in the upper 60s to lower 70s within the humid
conditions.

In addition, the warm-air advection within the increase in southerly
flow will lead to low rain chances Friday - Sunday. Think most of
this activity will likely remain below the capping inversion, but
will include the mention of thunder in the official forecast. Highs
Thursday through the end of the period will warm from the 80s for
most locations into the upper 80s to upper 90s by Sunday.
