SHORT TERM
(Today through Friday Night)
Issued at 259 AM CDT Thu Apr 25 2024

If you liked yesterday, you're in luck for today. Persistent onshore winds at the lower levels combined with an increasingly southwester- ly flow aloft will help to maintain this warm and increasingly humid airmass already in place across SE TX. With the potential for embed- ded shortwave activity, ahead of the main longwave trough tracking E from the Colorado Rockies, we could see some isolated showers pop up across our western/northern CWA this afternoon. Rain chances will be going up further tomorrow as the mid/upper trough finally begins its trek into the Southern Plains...with the best POPs likely across our northern CWA once again. This system should help to tighten the grad- ient across the region starting today and especially tomorrow, which will result in strengthening southerly winds and increasing moisture levels. But, despite all of these features coming together tomorrow, there is the matter of the strong cap already in place here. The SPC Day 2 outlook does have the northern third of the the CWA (generally along and north of a Columbus to Livingston line) in a Marginal Risk (level 1 of 5) for strong to severe thunderstorms for tomorrow. This could be mainly in response to the possibility of outflow boundaries and/or the tail end of the more organized activity which is expected further north of the CWA

As for temperatures...highs today/tomorrow are going to in the lower to mid 80s...with lows tonight/tomorrow night mostly in the lower 70s.

LONG TERM
(Saturday through Wednesday)
Issued at 259 AM CDT Thu Apr 25 2024

The boundary that approached the region on Friday will have retreated back north by Saturday ending the showers and storms threat temporarily. Saturday will be quite toasty as we see continued moist southerly flow at the surface and southwesterly flow aloft. High temperatures will be in the mid to upper 80s with heat indicies in the low to mid 90s. The hot and humid conditions will continue through at least the middle of next week. Overnight lows will possibly be near record warmth with minimum temperatures in the low to mid 70s.

An upper level shortwave will move into the Southern Plains on Sunday not only pushing that boundary closer to our region, but also reinvigorate the showers and storms along the boundary. The Bryan- College Station area could see precipitation start as early as sunrise Sunday with all of SE Texas getting scattered showers or storms by the afternoon. Areas north of Conroe will likely see the highest coverage of storms as it will be closer to the stalled boundary - but if that boundary moves further south then that increased coverage will follow. Wherever the stalled boundary ends up, it will remain there through Wednesday bringing daily rain chances.

AVIATION
(12Z TAF Issuance)
Issued at 630 AM CDT Thu Apr 25 2024

IFR ceilings have spread across the CWA this morning with some patchy LIFR readings added in. Conditions should improve by late morning (or early afternoon) for most inland locations, but terminals closer/near the coast could see MVFR CIGs linger through the day. These lower CIG levels should return areawide this evening...and persisting into much of tomorrow (Fri). S/SE winds to start from 4-9kts this morning, then increasing to 11-17kts/G20-26kts this afternoon. These gusts are like- ly to diminish by this evening with S winds staying somewhat elevated (in the 8-14kt range). 41

MARINE
Issued at 259 AM CDT Thu Apr 25 2024

The onshore flow will strengthen through the day today becoming moderate to strong tonight through the next several days. A Small Craft Advisory is in effect this evening through Friday afternoon as the winds increase to around 20kts with gusts to 25-30kt and wave heights increase to 6 to 8ft. The Small Craft Advisory will likely be extended into the weekend as the winds increase due to a tightening pressure gradient to around 25kt with gusts to 35kt possible. Wave heights peak to around 9 to 11ft Saturday into Sunday morning. Conditions slowly improve late Sunday into Monday. The persistent onshore flow will also lead to a high risk of strong rip currents Friday and through the weekend along with elevated tides.
