SHORT TERM
(This evening through Saturday Night)
Issued at 205 PM CDT Fri May 16 2025
Forecast for this afternoon remains on track, as many of you can feel right now with the Texas summer heat. Upper 80s/90s highs with heat indices breaking the triple digits are still on the tap for this afternoon, threatening to break daily high temperature records and several locations. Looking past the heat nowcast, we'll also be monitoring the position of a cold front, dry line and sfc trough currently over central Texas. The consensus of CAM guidance keeps these boundaries closer to the Dallas/Fort Worth area, with convection firing off along the line and tracking east/east northeast. Guidance suggest that this activity could clip our northeastern counties this evening (7PM-12AM window) as activity broadly starts to fizzle out. SPC respectively has the northern fringes of our CWA under a Marginal (level 1/5) Risk for severe weather this evening. Overall the severe weather threat looks incredibly slim, especially given how late in the evening it is, though non-zero and at least worth a mention. If we get a "Little supercell that could" then we'd have to watch for damaging winds and hail, though again this threat is very slim and unlikely to manifest.
Ridging across the Gulf of America amplifies with mid level heights progged to rise to 587-590 dam. NAEFS mean 500mb heights and 850mb temperatures are progged to still be over the 90th climatological percentile, potent enough to keep these abnormally hot conditions in place throughout the day. Short range guidance is still pessimistic on the notion of mixing, even after several days of dewpoints mixing into the 60s. More interestingly, 925mb dewpoints in the HRRR show some moisture convergence near Central/East Texas. Greater low level moisture around this area seems to at least partially mitigate the effects of mixing, though not completely. Regardless, we're still starting down highs in the upper 80s/90s and heat indices in the upper 90s to triple digits.
The combination of WBGT and heat risk indicate that this level of heat will primarily impact groups more sensitive to heat, though it would be wise to practice heat safety regardless if you plan to spend an extended amount of time outside. In addition, make sure to look before you lock your car.

LONG TERM
(Sunday through next Thursday)
Issued at 1251 PM CDT Fri May 16 2025
Deep mid/upper ridge remains in place over the Gulf into early next week, keeping the hotter than normal regime in place through Tuesday. So expect more humid conditions with highs mostly in the 90s until then. However, the flow pattern over Texas will be in flux by Tuesday thanks to a mid/upper trough over W CONUS ejecting eastward into central CONUS. The resulting surface low over the Central Plains should push eastward towards the Ohio River Valley. But the trailing cold front is expected to push southward towards the Gulf. Question is, will capping limit convection or could we have enough lift on Tuesday to foment convection (showers/thunderstorms)? Another question I have for Tuesday is how hot could SE Texas temperatures get? A well mixed LL veering wind profile could enhance WAA, giving Tuesday's temperatures a boost. Maybe we could see upper 90s in some areas. The post frontal air mass appears less humid. At a minimum, that would equate to cooler nights and less stifling days. But some guidance suggests would could see a more substantial cool down than what we have in our official forecast. We shall see if we are so lucky.

Bit of a rinse and repeat forecast:
- Currently VFR inland, MVFR at the coast with CIGs around 1800-2000ft - After sunset, MVFR conditions will spread from the coast inland with much of the region seeing CIGs around 1800ft by 6z. IFR conditions will be possible south of I-10 overnight with CIGs down to 800ft possible. Patchy fog will also be possible, but main driver of flight conditions will be CIGs .
- VFR conditions return Sunday mid-morning inland, but MVFR conditions may persist at GLS through the afternoon.
- Southeasterly winds around 7-10kt will prevail overnight with gusts to 20-25kt returning late Saturday morning.

Issued at 1251 PM CDT Fri May 16 2025
Generally light to moderate onshore flow is expected over the next several days. A steepening pressure gradient is expected to result in somewhat higher winds on Monday into Tuesday, especially at night and during the morning hours. Caution flags may be warranted. Considering the long fetch, we cannot rule out seas reaching Small Craft criteria over Gulf on Monday and Tuesday.
Winds may shift more north to northeast by Wednesday and Thursday thanks to a passing frontal boundary.
