SHORT TERM
(Today through Thursday Night)
Issued at 231 AM CDT Wed Apr 24 2024

Overall, the forecast for SE TX will remain a quiet one through the short term...with perhaps a slight chance of a shower or two (main- ly across our northern CWA) and a general trend towards warmer more humid conditions (for the entire CWA).

Persistent onshore winds will continue to deepen low-level moisture over the region today and tomorrow as surface high pressure lingers to our east (along the eastern Gulf coast). Aloft, the increasingly NW flow will help to push a couple of weak disturbances into/across the state. This along with daytime heating could produce some very isolated showers this afternoon, generally in/around locations from the Brazos Valley to the Piney Woods. We could see a repeat of this same scenario for tomorrow as a lot of the large scale features re- main in place. Rainfall totals (if any) will be very light.

So, with mostly cloudy/partly sunny skies, highs today and tomorrow will run in the lower to mid 80s range...in the upper 70s along the beaches
Tonight, lows will be in the mid and upper 60s
then into upper 60s to lower 70s tomorrow night. 41

LONG TERM
(Friday through Tuesday)
Issued at 231 AM CDT Wed Apr 24 2024

A cold front associated with a low pressure system moving through the Central Plains on Friday will approach - but not pass through - our area on Friday. This will cause a tightening pressure gradient across the western Gulf breezy southerly winds and increased temperatures and humidity. The front will approach close enough to bring some isolated to scattered showers and storms for areas generally north of Conroe Friday morning/afternoon. This cold front becomes a stationary front and retreats back to the northwest keeping SE Texas in the heat and humidity through the weekend. Another disturbance is looking to move through the Southern Plains Sunday into Monday reinvigorating showers and storms along the boundary. The boundary is expected to move far enough east to bring those showers and storms to our region Sunday into Monday, but again doesn't quite make it all the way through keeping the heat and humidity in SE Texas into the middle of next week (and looking like through the rest of Summer at this point).

High temperatures on Friday will be in the low to mid 80s and then mid to upper 80s over the weekend and into next week. Heat indicies are likely to climb into the low to mid 90s starting on Saturday.
Overnight lows will be in the low to mid 70s for the entire long term.

AVIATION
(18Z TAF Issuance)
Issued at 1143 AM CDT Wed Apr 24 2024

Intermittent MVFR ceilings will continue over the next couple of hours, but will lift to VFR at all area sites this afternoon as cloud cover scatters out. Some isolated showers will be possible this afternoon around CLL/UTS. Expect southeasterly winds around 10 knots to persist into tonight before becoming lighter and trending towards light and variable. Another round of MVFR ceilings in on tap for tonight spreading in from southwest to northeast. Some model guidance is even suggesting high-end IFR ceilings west of I-45 late tonight into early Thursday morning.
VFR conditions should return by the mid morning hours on Thursday as gusty southeasterly winds pick up.

MARINE
Issued at 231 AM CDT Wed Apr 24 2024

Light onshore flow and low seas will continue through tomorrow morning with winds strengthen tomorrow night into Friday morning ahead of some approaching weak boundary. This boundary will remain stalled to the northwest into the weekend continuing the moderate to strong onshore flow. The winds will strengthen to around 15-25kts with occasion higher gusts, so small craft may will likely need to exercise caution as early as Thursday night and Small Craft Advisories may be needed heading into the weekend. The increase in winds will also lead to an increase in seas to around 5 to 8 feet.
The persistent onshore flow will also lead to a high risk of strong rip currents Friday and through the weekend along with elevated tides.
