Issued at 1219 PM CDT Mon Mar 30 2026 Sunny to partly cloudy skies are expected for the rest of the afternoon to evening hours. The highs today will peak in the mid to upper 80s for most inland portions and the mid to upper 70s along the coast. Clouds and areas of patchy fog will re-develop again later tonight into early Tuesday morning. The lows will be in the mid to upper 60s for much of the area. The day will start off cloudy again on Tuesday morning and fog, if any, is expected to burn off shortly after sunrise. Skies will become partly cloudy in the afternoon and winds will strengthen as the local pressure gradient tightens along the Texas coast. Expect southeasterly winds of around 15-20 mph over areas west of I-45 and south of I-10 and 10-15 mph elsewhere. The highs on Tuesday will be in the mid to upper 80s for most of our inland locations and the upper 70s along the coast. Upper level weaknesses will pass through the region during the day and could lead to a few sprinkles, mainly for areas south of the Brazos Valley and Piney Woods region. Tranquil conditions are expected for Tuesday night with warmer lows, generally between the upper 60s and lower 70s. Although there is a chance for patchy fog again overnight and early Wednesday morning, winds may be strong enough to deter its formation over areas with wind speeds in the 6-10 mph range. Low level moisture will increase on Wednesday and PWs are expected to rise to 1.3- 1.5" by Wednesday morning. Skies will go from mostly cloudy to partly cloudy as the day progresses and highs will peak in the mid to upper 80s inland and the upper 70s along the coast once again. There is a chance for some showers and a few thunderstorms on Wednesday, as weaknesses along the mid levels pass through and tap into the higher moisture amounts. It will possibly have to counteract a bit of ridging along the upper levels, thus, significant rainfall on Wednesday isn't expected at this time. But, something is better than nothing :D. We should see an increase in showers and thunderstorms on Thursday as a mid to upper level trough moves through the Southern Plains and storms developing over northern and central TX Wednesday night push into Southeast TX during the day. Timing of the storms are still a little uncertain. The GFS is more progressive with pushing the storms across Southeast TX during the early morning hours, while ECMWF and NAM have them move through several hours later. We will know a little more once the Hi-Res models start to roll in for Thursday. The good news is that we may finally see some good soaking rains with this activity. Temperatures will also be cooler during the day, thanks to the increased cloud coverage and rainfall; the highs will be mostly in the upper 70s to lower 80s. Friday will be drier, but we should see an increase in rain chances again this upcoming weekend as another upper level trough moves across the Southern Plains and a cold front moves across Southeast TX Saturday night into Sunday morning. Cooler air is expected in the wake of the front and we could be seeing highs in the upper 60s to lower 70s on Sunday and lows in the upper 40s to lower 50s Sunday night. Cotto && .AVIATION...
