Key Message:
- Humidity surges back northward tonight through Tuesday with returning rain and thunderstorm chances into Tuesday afternoon.
A stalled surface front will remain settled near our southeastern border with the CRP/HGX CWA today. For the vast majority of our region on the dry side of this front should see clear skies and a rain free forecast today with dew points in the 40s and 50s. The locations nearest to the front, like eastern Lavaca county, where low-level moisture will be higher could see some cumulus and the slim chance of a shower or storm. The dry air and the abundant sunshine will lead to a very warm day with afternoon highs in the mid to upper 80s trending common and into the low to mid 90s for locations along the Rio Grande. The light winds will shift from northerly to more easterly with progression through the day.
The front lifts back northward tonight into Tuesday morning as a warm front and the winds respond by shifting from more out of the southeast. This will allow for low-level moisture to surge back across the region with dew points into the mid 60s regionally by midday Tuesday. The latest model guidance indicate with minimal capping that the warm and moist air advection could help to allow for isolated to widely scattered showers and storm activity to develop to the south and lift northward into the area on Tuesday afternoon. Additionally, the dryline to the west and the higher Mexico terrain will also see additional development towards the evening hours. This activity will likely wait until beyond sunset and occurs within the first period of the long term. More details can be found in the long term discussion but this is the round of activity that prompted SPC to highlight a level 1 of 5 risk for severe weather over portions of the Hill Country and Southern Edwards Plateau. However with that said, quickly building MLCAPE values to around 1500 J/kg and sufficient deep layer shear of 35 to 40 kt, could support an isolated strong to possibly severe storm during the afternoon in that warm, moist air advective regime.
Temperatures on Tuesday will again trend very warm with the highs ranging from the mid 80s in the Hill Country to the 90s for the locations on the Rio Grande. Low stratus establishes with the returning low-level moisture into Tuesday morning and expect for partly cloudy skies through the afternoon.
LONG TERM
(Tuesday night through Sunday)
Issued at 136 AM CDT Mon Apr 21 2025
Key Message:
- Warm, humid, and active pattern expected through the long term with near daily rain/storm chances.
Broad troughing over the western CONUS will allow southwesterly flow aloft to continue through late week. Along with deep layer moisture up from the sfc to 700mb level, expect showers and thunderstorms, some of which could be strong to severe, on Tuesday night and stretching through Wednesday morning. The Storm Prediction Center currently has our western half painted with a Marginal Risk for severe storms. A mid- level shortwave will be working through the region on Wednesday, sparking showers and storms through the afternoon and early evening hours as well.
Yet another mid-level shortwave looks to work through the region Thursday-Friday, bringing a lower chance at rain and storms, but a chance nonetheless. By the weekend, some weak shortwave ridging is possible, particularly on Saturday, which could limit shower and storm development. Beyond the weekend, medium range guidance is split on the next thing, but believe weak southwesterly flow aloft will continue. While the threat for rain is higher this week, uncertainty exists as to the extent of rainfall that may fall from storms as well as timing different storm regimes. Warm and humid conditions develop on Tuesday and continue through the remainder of the weekend.
AVIATION
(12Z TAFS)
Issued at 610 AM CDT Mon Apr 21 2025
VFR flight conditions continue through this evening at the local TAF terminals underneath mainly clear skies. Low-level moisture returns by the overnight and low stratus with MVFR ceilings will establish between 08Z and 10Z at all sites. Brief IFR ceilings may develop at KSAT nearing sunrise Tuesday. Winds remain of 10 kts or less for all sites with directions shifting from northerly this morning to more easterly this afternoon to east-southeasterly later on tonight.
