A mid-level high moving into the southeastern Texas region tonight and into the northern Gulf on Sunday, will continue to give us dry conditions. Northeasterly winds will decrease this evening into tonight as the high pressure moves closer to our region. For tonight, expect mostly clear to partly cloudy skies and low temperatures in the lower 50s to lower 60s inland and the mid to upper 60s along the coast.

Sunday will be a mostly sunny day with highs in the lower 80s for much of the inland areas and the mid to upper 70s along the coast. Winds will be light and variable in the morning and southeasterly at around 10 mph in the afternoon. The return of onshore winds will push through a small patch of moisture into Southeast TX from the Gulf and will lead to low temperature and dewpoint departures during the overnight to early morning hours. Thus, we can expect skies to become cloudy overnight as well as have some development of patchy fog over portions of the region.

Tranquil conditions continue into Monday with fog burning off shortly after sunrise and skies becoming sunny by the early afternoon hours. Temperatures will be warmer on Monday as highs increase to the mid to upper 80s mostly over areas west of I-45 and north of I-10. For the rest of the inland areas, highs will be mainly in the lower to upper 80s while the coast remains in the upper 70s. Once again, clouds will build back in from late Monday night into early Tuesday and we could have some more patchy fog developing through around sunrise. On Tuesday, the pressure gradient will tighten along the Texas coast, leading to southeasterly winds at 15-20 mph over areas west of I-45 and 10-15 mph over areas east of I-45. This will also bring up moisture transport (PWs rising to 1.1 to 1.3") and further increase our high temperatures, ranging in the upper 80s for most of our inland locations. A few weaknesses could pass overhead throughout the day and there might be a chance for a few sprinkles over our coastal locations.

Better chances for rain can be expected Wednesday into Thursday as a mid to upper level trough moves through the Southern Plains and a cold front moves over the north-central portions of Texas. Some models are a bit uncertain as to whether the front stalls to our north or if it moves into Southeast TX. Regardless, we could at least experience moisture convergence on both days, and PWs might jump into the 1.3-1.5" range on Wednesday and the 1.5-1.8" range on Thursday. The forecast carries isolated to scattered showers and thunderstorms for both days, with Thursday being our rainiest day (better dynamics and more moisture). This is finally some goods news given that we desperately need rain since Southeast TX continues to be under Severe to Extreme Drought levels according to the U.S. Drought Monitor. Additional chances for some lighter rain showers may be possible on Friday as another upper level trough swings through, but will depend on how unstable and moist we will be.
