SHORT TERM
(This evening through Friday Night)
Issued at 1243 PM CDT Thu May 15 2025
Hot weather continues today with similar conditions to that of yesterday. 500mb Heights are on the rise as the center of a midlevel high shifts over the western Gulf of America. A 850mb low/trough pushing eastward has tightened the pressure gradient thus strengthening the LLJ to 30-45 knots. While 850mb temperatures are a tad weaker than the day before, the strengthened LLJ should amplify WAA, with the HRRR showing temp advection reaching upwards of 1.0- 3.0 K/hr at times on the higher end of the distribution, though notably less potent than previously forecast. HRRR and CAMs continue to show lackluster mixing in spite of the strong winds in the lower levels. It'll remain to be seen, though I wouldn't be surprised if we saw dewpoints drop into the upper 60s in some locations. Taking account for all these factors, in addition to greater cloud cover, the heat should be tolerable enough, such that to avoid the need for a Heat Advisory today. Experimental Heat Risk has been calculated to be Moderate to Major (3/5 - 4/5), though given the aforementioned meteorological conditions, this level of heat will mainly affect individuals more sensitive to heat. WBGT heat stress will peak at Moderate to High (3/5 - 4/5) this afternoon. Overall similar to yesterday, though broadly favoring a lesser heat risk, thus will continue to hold of on a Heat Advisory.
Friday rolls around with broadly the same pattern, but a few important differences. 500mb heights across the Gulf of America and surrounding coastlines should continue to creep upwards. The northern shift of the western trough axis should slowly weaken the pressure gradient, causing the LLJ to weaken from 30-40 knots to as low as 20 knots in the afternoon. This means winds won't be as gusty as Thursday, though still sufficient to make the heat more tolerable. Subsequently, WAA is also reduced to 0.5-1.5 K/hr, limiting the added heating from advection. ECMWF EFI for MaxT ranges form 0.5-0.95 with NAEFS 850mb temps only above the 90th percentile.
850mb temps are also low than past days in the CAMs too. Once again, models are pessimistic on the extend of mixing during the afternoon, showing fairly high dewpoints in the uppers 60s/70s. Taking a brief detour from talking heat, a frontal boundary/dry line may push into the vicinity of the Brazos Valley Friday afternoon, which could initiate some isolated thunderstorms across our northern counties.
While only select CAMs show this (Fv3), it's still be worth maintaining some light PoPs. Back to heat, Heat Risk is still forecasted too be Moderate to Major (3/5 - 4/5) with WBGT heat stress reaching Moderate (3/5) at least in the afternoon. With similar meteorological conditions, this level of heat should primarily affect groups more sensitive to heat.
If you plan to spend an extended amount of time outdoors, be sure to drink plenty of water to stay hydrated.

LONG TERM
(Saturday through next Wednesday)
Issued at 1243 PM CDT Thu May 15 2025
Mostly tranquil conditions are expected to prevail across Southeast TX through the next several days as a mid-level high pressure meanders over the Gulf.
Mid-level heights in the 587-590 dam range will prevail this weekend, along with hot conditions and high temperatures remaining in the mid to upper 90s for most locations north of I-10, the low to mid 90s for locations south of I-10, and the upper 80s to lower 90s along the coasts. To give you another perspective, these temperatures are roughly between 5-11 deg above average for this time of the year.
Aside from the highs, we will need to keep in mind the added effect of winds and moisture. South to southeasterly flow will continue to supply warm moist air from the Gulf this weekend while a weak boundary stalls over Central TX. This will lead to moisture converging over our area and increasing PWs into the 1.6" to 1.8" range. As a consequence, conditions will feel much warmer. The current forecast carries Heat Indices between 100-107 deg F inland.
Now...the boundary stalling over Central TX may also lead to a tighter pressure gradient over our area, and thus, slightly stronger winds along the surface. This could bring a little relief to some, however, heat impacts will remain to be a concern.
Keeping in mind that many are not yet acclimated to these conditions, there is the possibility of heat related headlines and/or a Heat Advisory for portions of Southeast TX during weekend.
Make the proper preparations to keep yourself, your family, and pets safe from heat related impacts, including limiting outdoor work and activities, taking frequent breaks in the shade or a room with AC, stay hydrated, and limit sun exposure. Be aware of heat related illnesses and be ready to act quickly if symptoms arise.
By early next week, a mid-upper level trough will move across the Southern Plains and some locations could see high temperatures a couple of degrees cooler - closer to the low to mid 90s range - although a few spots may still see highs in the upper 90s (in particular over the Brazos Valley region). An associated weak cold front looks to stall over Central TX again, leading to another rise in PWs (ranging between 1.7" to 2.0"). Although the front will not make it into Southeast TX, it will at least tighten the local pressure gradient. This could then lead to stronger surface winds on Monday and Tuesday, roughly 15-20 mph, which may subside some of our heat impacts. The Brazos Valley and Piney Woods region also have a chance for some showers and thunderstorms on Tuesday and can briefly provide slightly cooler conditions for a few areas. Regardless, it is recommended to remain alert and prepared for any heat impacts for the next several days.

MVFR conditions occurring at HOU/IAH/SGR/GLS. All other sites at VFR. Expect MVFR conditions at all sites around 06Z.
HOU/LBX/SGR/GLS may experience a few hours of IFR CIGs overnight into just after sunrise Friday AM. VFR conditions will return to all sites around 16-17Z. Winds will be light out of the south overnight, becoming breezy out of the south during the mid to late morning hours through the afternoon. Gusts of 20-25 knots will be possible. MVFR CIGs will return after 00Z.

Issued at 1243 PM CDT Thu May 15 2025
With a surface high pressure centered across the eastern Gulf, south to southeast winds will continue through most of the period. Winds are expected to weaken the rest of this afternoon and evening, falling below advisory levels. However, seas offshore will still be into the 6 to 7 ft range, occasionally higher through early this evening. Small Craft Advisory remains in effect until 7PM CDT. Light to moderate onshore winds will prevail at least through next Wednesday. Winds and seas could reach advisory levels at times early next week. Overall, dry and warm weather will prevail within the next 7 days.
Beach and Swimming Conditions: Above average water levels are expected, especially during the high tide cycles. This could result in isolated/minor coastal flooding due to elevated tides through early this evening. The risk of rip currents also continues along all Gulf-facing beaches and will likely persist into the weekend.
