SHORT TERM
(This evening through Thursday Night)
Issued at 406 PM CDT Wed Apr 24 2024
♬ Guess who's back...back again! Humidity's back...tell a friend! ♬ I'm sure y'all felt the difference outside between this morning and Tuesday morning as temperatures ran 10-15°F warmer due to increasing moisture. It felt flat out muggy and gross outside this morning, and don't expect that to change anytime soon. Surface high pressure continues to sit off to our east allowing for warm, moist Gulf air to funnel in to Southeast Texas. PW values will generally remain in the 1.2"-1.4" range (75th percentile: ~1.40") throughout the short term period. With northwesterly flow aloft being established due to ridging aloft building in, we'll see a few passing shortwaves that may be enough to kick off some isolated light rain showers around the area. A fairly robust subsidence inversion layer aloft between 850-750mb will likely inhibit most of the coverage. Cloud cover scattering out this afternoon will allow for temperatures to warm into the low to mid 80s. Going into tonight, low-level cloud cover will build in again from southwest to northeast leading to a slightly milder night as we bottom out in the upper 60s to low 70s.
There is some potential for patchy fog east of I-45 tonight into Thursday morning.
Thursday is essentially a rinse and repeat forecast, but with one difference...it's gonna be a bit breezy! Temperatures in the afternoon will top out in the low to mid 80s once again. With an upper level trough approaching from the southwestern CONUS, a resultant surface low develops on the lee side of the Rockies on Thursday leading to a tightening pressure gradient. Southwest flow aloft becomes established by Thursday night as the upper level trough transitions to the Central Plains and evolves to have an embedded upper low. Deepening surface low pressure results in the development of a 25-35 kt LLJ in Central Texas that drifts over Southeast Texas beginning Thursday afternoon. By Thursday night, the LLJ will strengthen to 35-45 kt, so the elevated winds will persist during the overnight hours. Low level cloud cover filling back in on Thursday night combined with elevated winds mean that we won't see much cooling. I nudged temperatures up a little bit above guidance to reflect widespread lows in the low 70s. This'll be another night that we may come close to some record high minimum temperatures.
That's a sign of things to come for the foreseeable future...and there's a fairly decent chance that this past Monday night/Tuesday morning may have been our last time in the 50s till the fall. This is the one time that I hope I'm wrong!
LONG TERM
(Friday through next Tuesday)
Issued at 406 PM CDT Wed Apr 24 2024
♬ Humidity's created a monster, the atmosphere don't want seasonable no more, it's summer, spring's chopped liver ♬
Hopefully y'all have taken advantage of our stretch of fair weather and temperatures that have been warm, but not too hot...because the long term portion of the forecast will give us a bit of change on both fronts at one point or another this weekend into the first half of next week.
We'll start by shifting things up to a bit more of an unsettled pattern. Come Friday morning, the subtle ridging that's been in place over the region will be amplifying, but it will also have moved off to the east. Both of these will be in response to the arrival of a stout upper trough dropping off the Colorado Rockies.
Of course, this will induce lee cyclogenesis over the Central Plains, and guidance continues to indicate a pretty strong surface low. In turn, this induces increased southerly low level winds feeding rich, Gulf air into Texas.
And...you might think I'm setting things up to talk about a severe thunderstorm setup. While that's definitely true for somewhere (north of here), it's not really a driving concern in our area.
While we'll have warm, moisture rich boundary layer air moving in, it will be happening under southwest flow just aloft - which should largely cap us off, moving the primary focus for severe weather up to the dryline/cold front. Now, with the front making its way to the region, we are not completely devoid of a severe threat. Those folks way up in our northwest (the Caldwell, B/CS, Madisonville, Crockett types) will need to be aware of just how far the front can push before stalling out, or how far ahead of the front the threat can ride on outflow boundaries, and the storm/severe threat is not zero. But with both the surface low and upper trough already so far north and ejecting to the Great Lakes, that will cause the front to stall out short of our area.
Saturday, we take our next crack at things as the next upper trough makes its way in. Though this trough looks to dig a little deeper, it doesn't look quite as potent, the surface low looks weaker, and is probably a bit slower. Again, this should keep us capped off and focus the severe threat to the north in Oklahoma and North Texas. Our northern spots may again be keeping an eye out to the north for some residual nighttime action, but with the focusing mechanism even further to the northwest, odds should be even lower, putting Saturday as the fairer day of the weekend. It should also be noticeably hotter, with highs in the upper half of the 80s.
As the upper trough continues to push its way through the Plains Sunday into Monday, we'll finally see a better chance of rain and storms in the area. Without much change in the broader environment, the best severe potential again is likely to mostly be north of the area. But, as initiation will be closer to the area, there'll be a marginally better shot at a stronger storm or two. There is a chance we could see some briefly heavy rain in the stronger stuff, as both NAEFS and EPS indicate that we'll have meridional flow above the 90th percentile, which also coincides with some stout moisture transport into/through the area. Though that upper trough will be exiting, another shortwave trough looks to ride its coattails across North Texas, helping keep the fun going through Monday, and perhaps even into Tuesday with more on/off rounds of showers and storms. Towards mid-week, we'll finally start to see some ridging aloft try to build in, which will give us a shot at some fairer weather. However, it's worth noting that deterministic guidance several more shortwaves in the pattern, so we may not see the tap turn entirely off. Something to pay attention to in the coming days.

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.

Moderate onshore flow and fairly low seas will continue through Thursday morning. Winds and seas will be on an upward climb late Thursday and into the weekend as a long fetch of moderate to strong southeast winds set up across the Gulf. Small Craft Advisories are likely Friday into Saturday night.
At the coast, the persistent onshore winds will help to push water levels up, so going into the weekend as those winds strengthen, we may need to keep an eye on how high above astronomical tides those water levels will push. Additionally, the stronger winds should increase the threat for rip currents going into the weekend.
HYDROLOGY

Minor river flooding continues along portions of the Trinity River due to runoff from previous rounds of rainfall. The Trinity River at Liberty (LBYT2) remains in minor flood stage, but is on a downward trend and is forecast to fall out of flood stage as early as late this afternoon/early this evening. The Trinity River at Moss Bluff (MBFT2) is still on an upward trend in minor flood stage and is forecast to reach its crest on Thursday afternoon. This site is forecast to remain in minor flood stage until further notice. The Trinity River at Riverside (RVRT2) will remain in action stage going into the weekend.
