light onshore flow and low seas will continue through Thursday. The onshore flow begins to strengthen Thursday night into Friday morning ahead of some approaching weak disturbances. The winds will strengthen to around 15 to 25 knots 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.

SHORT TERM
(This evening through Wednesday Night)
Issued at 218 PM CDT Tue Apr 23 2024

A look at the satellite this afternoon will confirm from above what you can also likely see from your nearest window - it's mostly cloudy out there. The exception is out towards the Piney Woods in parts of Houston, Trinity, and Polk counties, where it will remain tree canopy that blocks your view of the sky, not the clouds. Despite that, we are continuing the expected warming trend, with temperatures reaching into the middle 70s throughout the region, on pace for highs in the upper half of the 70s for most in the next few hours.

If you like your nights a bit chillier - firstly, I congratulate your good taste, but also I have some bad news. With clouds staying in place, and onshore flow continuing to pump in higher dewpoints, we are assured to have a higher temperature floor overnight as well. Lows tonight look to be a good 10-15 degrees higher than last night, ranging from the low 60s in the far north to right around 70 degrees on the Gulf. This of course, sets us up for another warm day tomorrow, in spite of another day that's anticipated to be mostly cloudy. Starting as warm as we are, highs should nudge up to around or above 80 degrees area-wide.

Outside of the temps and continued onshore winds, there's not a whole lot else of note in the short term. I did struggle with rain chances. We've got a decently low cloud base and increasing moisture, which has me thinking we can manage a smattering or real light, real quick sprinkles/light showers. But since these tend to struggle to manage more than a trace of rain, and the PoPs are defined by having measurable rain, I chose to keep those rain chances low, below the threshold for a slight chance mention. Even if you stipulate one of these quick hitter sprinklers, the odds aren't great for getting even a hundredth of an inch out of them. Luchs

LONG TERM
(Thursday through next Monday)
Issued at 218 PM CDT Tue Apr 23 2024

Upper level ridging from Mexico into Texas will be transitioning eastward on Thursday. This will open us to more of a swly flow aloft with broad mid-upper troffiness situated across the western CONUS as we close out the week.

As far as the local forecast goes, look for increasingly breezy conditions as we head into the weekend as the pressure gradient tightens. With steady winds coming in off the Gulf, I'd anticipate mcldy skies, humid conditions and overnight low temperatures resembling those of early June (low 70s). Though slightly above normal, cloud cover should keep readings in the 83-87 range most days.

Despite somewhat moist conditions, other some some diffuse impulses moving overhead from time-to-time, there really isn't much in the way of distinct triggers or focusing mechanisms needed for widespread chances of rain. There are a few possible exceptions we'll be keeping an eye on (mainly for the northern parts of the CWA). Looks like there will be a few shortwaves drop into the base of the trof then eject into the Plains. As this occurs we might see the tail end of some associated bands of shra/tstms try to sneak into portions of the area. Friday and Sunday would be the days I'd be looking at if so. 47

AVIATION
(18Z TAF Issuance)
Issued at 1230 PM CDT Tue Apr 23 2024

A mix of VFR and MVFR around the area, but anticipate all TAF sites will see CIGs lift to VFR this afternoon, even if it's just barely in some spots. Clouds hang tight with us through the period, gradually coming back down to MVFR late this evening. Some guidance gets aggressive in this drop, going to low MVFR and even IFR in spots. This seems reasonable for short stretches, but not enough confidence in precise impacts to lay it out in the TAF this cycle. Future cycles may want to dig into this nuance a little more. Similarly, there could be a bit more wiggling in the winds, but for now stick with sketching out the broader S/SE pattern, becoming light/VRB late, and S/SE winds returning in the morning.
Finally, as moisture continues to deepen and ample clouds, some light showers here and there aren't impossible...but not significant enough to explicitly put into the forecast at this time.

MARINE
Issued at 218 PM CDT Tue Apr 23 2024

Onshore flow will continue through the week. Winds and seas will be on an upward climb later in the week and weekend as a long fetch of moderate to strong southeast winds set up across the Gulf.
Small craft advisories are looking increasingly probable as are high risks of rip currents on area beaches this weekend. 47
