New SHORT TERM
SHORT TERM
(Today through Wednesday Night)
Issued at 203 AM CDT Tue May 20 2025
Hot weather continues to be the main story through the short term, but less humid weather is expected to begin to filter into the region today following the passage of a weak boundary from the north. This boundary will be fairly diffuse, so the exact timing of its passage will be unknown, but the generally timing is through the Piney Woods/Brazos Valley region between 10am and Noon, through the Houston Metro between 2-5pm, and then not off the coast until sometime tonight. This boundary will bring dew points down into the 50s-60s behind it, but only areas north of I-10 will get to experience these drier conditions today. Areas along and south of I-10 will likely see hotter and muggier weather than the last couple of days. High temperatures today will be in low to mid 90s north of Harris County and along the coast, while temperatures along the I-10 corridor and down through northern Jackson County will rise into the upper 90s. The difference in dew points today will lead to a rather drastic gradient in heat indicies across the region with max HI's near the max temperature (low 90s) in the Piney Woods and Brazos Valley, but then into the 100-105 degree range along and south of the I-10 corridor with even seeing a few spots climbing above 105 degrees. Have decided against the issuance of any Heat Advisories, for now, as partly cloudy skies and occasional wind gusts to 10-15mph should limit heat indicies from climbing much higher than 105 degrees.
Nevertheless, please continue to practice heat safety today.
An isolated shower or thunderstorms may develop along the boundary this afternoon/evening as it moves through the I-10 corridor, especially east of I-45. SPC does include the eastern parts of Liberty and Polk counties in a Marginal Risk (level 1 of 5) of strong to severe thunderstorms capable of producing strong wind gusts this afternoon/evening, but the greatest risk of any severe weather will be well to our northeast.
Wednesday will see the continuation of the hot weather across SE Texas with highs in the low to mid 90s for most of the area, with a few spots near the Houston Metro approaching the upper 90s.
However, the drier conditions will be felt across the entire region limiting heat indices to near or just about the actual temperature. So while it will be hot, it will feel better than today for most of the area.
LONG TERM
(Thursday through Monday)
Issued at 1228 AM CDT Tue May 20 2025
The southern edge of a weak upper level trough will move overhead on Thursday. As it does so, mid-level moisture increases across Southeast TX and a few vort maxes will be pass overhead. While this would give us a better chances for rain development, we will need to see if the lower levels have recovered enough moisture and instability for showers to develop or if we will end up fighting the cap. As of now, PWs may range between 1.1" to 1.3" for areas north of I-10 and 1.3" to 1.6" for areas south of I-10, which may be sufficient to support the development of afternoon/evening showers and isolated thunderstorms if no capping is present. That being said, models are keeping Thursday on the dry side, but I believe we have a chance for some development Thursday afternoon.
Thus, I'm comfortable with keeping the inherited ~20% PoPs for that timeframe. The high temperatures on Thursday are expected to be 5-10 deg F above normal for that day, ranging between the mid to upper 90s for most inland areas and the upper 80s to lower 90s along the coasts.
Sunny to partly cloudy skies and highs generally in the lower to mid 90s are expected Friday into Saturday as the upper level ridge returns to Southeast TX. Sunday is a bit of a toss up for me at the moment. Low level moisture increases to 1.5" to 1.8" Sunday afternoon, and models are hinting at some sort of boundary (maybe an outflow boundary from a nearby storm or weak front) around the Piney Woods and Brazos Valley region. They also show fairly good sfc CAPE values of around 3,000 J/kg in and around this area. So naturally, it's where we could be expecting the better chances for rain to occur. However, I dont know if this will be enough to fight off the persistent upper to mid-level ridge overhead. Will keep the current NBM PoPs for Sunday afternoon/evening, carrying around 20-30% PoPs for areas north of I-10 and 15- 20% PoPs elsewhere.
A better set up for rain may occur on Monday (Memorial Day) as the ridge weakens and a few disturbances pass overhead throughout the day. We could also have storms developing to our north and northwest move into Southeast TX Monday afternoon or evening.
Models hint at some cooling on Monday as well, with highs possibly in the upper 80s for much of Southeast TX.

MVFR cloud decks and S winds at 8-12 KTS are expected overnight into early Tue. Decks are expected to lift mid morning and scatter out during the late morning to early afternoon hours.
A weak front will move into SE TX and stall, leading to variable winds throughout the day. We will have SW-W winds in the morning and see gradual change from NW-N during the afternoon to evening hours. Winds will then become N-NE Wed night.

MARINE
Issued at 1228 AM CDT Tue May 20 2025
Seas will gradually subside late tonight into early Tuesday as onshore winds decrease. Caution flags and Advisories will continue in effect through early Tuesday. Winds will turn east northeast late Tuesday into Wednesday as a weak front moves into Southeast TX. The frontal boundary shifts north-northeastward on Wednesday, bringing back the onshore winds, and this persistent flow could result in strong rip current along the Gulf facing beaches for a few days.
