SHORT TERM
(Today through Tuesday)
Issued at 213 AM CDT Mon Apr 21 2025
Key Messages:
- Patchy dense fog expected through around 9 AM.
- Low to medium chances (20-50%) for rain early this morning into the afternoon hours. The rain could be heavy at times.
The weak front that moved into the area yesterday continues to linger around the Coastal Bend early this morning and will slowly begin to lift back to the north later today. Prior to that happening, fog will become more widespread across the Coastal Plains, Victoria Crossroads, and Coastal Bend, with visibilities briefly dropping to near 1/4 of a mile at times. The fog will begin to dissipate a little after sunrise and should be mostly gone by 9 or 10 AM this morning.
We will also see some showers begin to redevelop as we head towards sunrise, particularly along the coast and up towards the Victoria Crossroads. We could also see a couple thunderstorms across the Coastal Bend late this morning into the afternoon before precipitation chances start to diminish heading into this evening. These thunderstorms can produce heavy rain and there is around a 20-40 percent chance of at least 1 inch of rain across the northern Coastal Bend into the Victoria Crossroads.
Clouds will clear out across much of the region this evening before some low clouds build back in tonight. Lows tonight will be in the 60s and 70s with highs tomorrow in the 80s and 90s with a mix of sun and clouds and around a 20 percent chance of a shower or thunderstorm.
LONG TERM
(Tuesday night through next Sunday)
Issued at 213 AM CDT Mon Apr 21 2025
Key Messages:
- Low to medium rain chances Tuesday night through Thursday
A series of disturbances will track across South Texas throughout the week, combining with the available moisture to provide additional chances for showers and thunderstorms. Wednesday is shaping to be the most active day of the Extended period, with PoPs at around 20-50% from south to north. However, in terms of rainfall accumulations, these won't be as impressive with totals generally staying below 0.5" areawide. By late week into the weekend, moisture availability drops as weak ridging builds aloft with PoPs falling to less than 30% Thursday and Friday, and to less than 10% by the weekend.
Temperatures will remain above normal all week with highs mostly in the low 80s to mid 90s range, and overnight lows in the upper 60s to low 70s. Next weekend will be hot, with highs potentially reaching the triple digits out west.
AVIATION
(06Z TAFS)
Issued at 213 AM CDT Mon Apr 21 2025

Expect LIFR conditions in the densest fog. Additionally, showers are expected to redevelop after 10-12Z across the Coastal Bend and Victoria Crossroads. Rain chances are expected to decrease by late this afternoon.
