...New SHORT TERM, LONG TERM...

.SHORT TERM...
(Tonight through Thursday night)
Issued at 152 PM CDT Wed Sep 18 2024

An upper level ridge continues to reside over the southern plains
this afternoon. The low level pressure field has become somewhat ill
defined. The flow, while generally from the southern half of the
compass, is a bit erratic over South-Central Texas. A warm, moist
airmass remains in place. Temperatures and dewpoints are 0-5 degrees
warmer than 24 hours ago. The upper ridge will strengthen during the
short term period. The low level flow will become better established
from the southeast tonight and continue through Thursday night.
Subsident flow from the upper ridge will keep the weather dry
through the period. The above normal temperatures will also
continue. Lows both tonight and tomorrow night will be mostly in the
70s. Some record warm lows will be possible both nights. High
temperatures Thursday will be in the 90s. Record highs are 100 and
higher. While we do not have any records in the forecast, some
places could be within a couple of degrees.

.LONG TERM...
(Friday through Wednesday)
Issued at 152 PM CDT Wed Sep 18 2024

Basically status quo again today. More of the same hot and dry
weather can be expected through the long term period. 500mb ridging
will remain in control late week into the weekend. While a trough
from the west will approach on Sunday, it will likely remain well
north of our region, resulting in a continued dry forecast. This
trough may still help to weaken the ridging in place and bring back
some weak southwesterly flow by the middle of next week. This could
result in some increased rain chances, but for now, chances are quite
low and hot and dry weather remains favored in the 6-10 day and 8-14
day CPC temp and precip outlooks for our region.

.AVIATION...
(18Z TAFS)
Issued at 1218 PM CDT Wed Sep 18 2024

Our late summer pattern of overnight low clouds and afternoon
scattered cumulus will continue for the next TAF period. VFR
conditions will prevail through the afternoon and evening. MVFR
ceilings will develop overnight and last through the late morning
Thursday. Winds will be from the southeast generally 10 kts or less.
