Issued at 1223 PM CDT Sun Mar 29 2026 We will continue to see dry and warm conditions through early this week as a mid-level high currently anchored over the northern Gulf gradually progresses eastward into western FL through Monday. Today's high temperatures will be in the lower to mid 80s inland and the mid 70s along the coast. Southeast winds expected this afternoon at around 10 mph. Skies will be mostly sunny this afternoon and evening, but clouds will gradually develop and skies will become partly to mostly cloudy during the overnight to early morning hours. There will be a chance for patchy fog during this period as well. The lows will be warmer tonight, generally in the lower 60s inland and the mid to upper 60s over the Houston Metro and the coast. Monday morning will start off cloudy and fog (if any) will quickly burn off around sunrise. Skies will gradually become partly cloudy during the late morning to early afternoon hours. The day will be warmer, with highs in the mid to upper 80s for most inland portions and the mid to upper 70s along the coast. For Monday night into early Tuesday morning, expect partly cloudy to cloudy skies and lows in the mid to upper 60s for much of the area. There will once again be a chance for patchy fog overnight into the early morning hours. Models do hint at a 25-30 knots low level jet developing Monday night into Tuesday morning, which may keep our winds slightly higher at night, and thus, inhibit fog development. On Tuesday, winds will be a little stronger as the 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. Our temperatures will warm up a little more on Tuesday, with highs expected to range in the mid to upper 80s for most of our inland locations. A mid-level shortwave looks to pass overhead on Tuesday and with a slight increase in PWs (thanks to the stronger onshore winds), we could see a few sprinkles during the day. Low level moisture will continue to increase on Wednesday, with PWs rising into the 1.3-1.5" range. It may also be one of the hotter days this week as highs peak in the upper 80s for most areas with some isolated spots over the Brazos Valley possibly reaching 90 degrees F. There is a chance for rain on Wednesday, but will depend on how east of us the upper level trough is. We had better chances for rain on yesterday's model runs, but today, the models show us under the western edge of the upper level trough and the start of the ridge. Regardless, we can still expected a few showers and isolated thunderstorms that day, although they may be mostly focused over areas along and east of I-45. A much better setup for showers and thunderstorm is expected on Thursday as a stronger mid to upper level trough moves through the Southern Plains and a cold front moves over the north-central portions of Texas. Moisture convergence over Southeast TX will ramp up low level moisture and PWs are forecast to rise into the 1.5-1.8" range. Unfortunately, the cold front is expected to stall over the north-central portions of TX. However, we may see the showers and thunderstorms that developed from the cold front push southward into Southeast TX during the day. With the slightly more unstable airmass, a few vort maxes passing overhead, and the higher PWs, these showers and storms may bring in some good rainfall over portions of Southeast TX. The rainfall will be much appreciated given that Southeast TX continues to be under Severe to Extreme Drought levels according to the U.S. Drought Monitor. Temperatures will be cooler on Thursday, thanks to the added cloud coverage and rainfall. The highs are expected to be mostly in the upper 70s to lower 80s. Additional chances for rain along with cooler temperatures look to be possible this upcoming weekend as another upper level trough moves across the Southern Plains and a cold front moves over Southeast TX. Cotto && .AVIATION... (12Z TAF Issuance) Issued at 630 AM CDT Sun Mar 29 2026 All sites at VFR this morning. Expect VFR to prevail through the day today. Winds may gust to around 20 kts at KCLL and in the vicinity this afternoon, otherwise, expect light SE winds. MVFR cloud deck will move into northern terminals around 10Z Monday morning. && .MARINE... Issued at 1223 PM CDT Sun Mar 29 2026 Light onshore winds and seas of 3 feet or less are expected for the first half of the week. By mid-week, the local pressure gradient will tighten, resulting in light to moderate winds and slightly higher seas for the second part of the week. Isolated to scattered showers and thunderstorms are expected during the second part of the work week as a few disturbances pass through. A cold front could move across Southeast TX during the upcoming weekend, leading to offshore winds in the wake of the front. Cotto && .PRELIMINARY POINT TEMPS/POPS...
