(This evening through Thursday Night) Issued at 253 PM CDT Wed Jun 5 2024 Light showers and thunderstorms will continue to move southeastward and offshore this afternoon. Skies will be partly cloudy tonight with lows in the mid to upper 70s for much of the area. Heat and humidity will be the main headline for Thursday as we continue to remain under the influence of high pressure. Highs will be in the 90s inland and in the upper 80s along the coast. Onshore winds will not be as strong, which will impact dew point values (for the better!) and help keep heat index values generally below 105F. A few locations may reach to above 105F. Continue to exercise caution with the heat by staying hydrated, avoid strenuous activity during the hottest time of day, and look before you lock. Thursday night`s lows will be in the mid 70s again Thursday night, and a few degrees below the record breaking values that have been observed the last few days. Adams

(Friday through next Tuesday) Issued at 253 PM CDT Wed Jun 5 2024 Upper ridge centered over the Four Corners will finally move eastward into TX on Friday, resulting in dry and hot conditions. Surface high pressure will move overhead Friday night into Sunday, thus, quiet weather should persist through at least Sunday. Any activity that attempt to develop will need to overcome the cap inversion. Longer range models continues to show more confidence in a more active weather pattern after Sunday, pushing a cold front into the area. Therefore, showers and thunderstorms will be possible as early as Sunday evening, continuing into Monday as the upper trough and associated boundary make its way to our region. After Monday, the pattern aloft becomes more favorable for several disturbances moving overhead. Daily rain and storm chances will continue through most of the upcoming week, especially during the peak daytime heating/sea breeze interaction. Temperature-wise, hot and humid conditions continue through the weekend with above normal highs. A slight relief in temperatures will be possible next week due to rain/storm chances; but overall, highs will be into the upper 80s to low 90s degF range. JM

(00Z TAF Issuance) Issued at 631 PM CDT Wed Jun 5 2024 Tricky forecast tonight in that there is high confidence that one of two scenarios will play out...and those two scenarios happen to be completely different. In coordination with CWSU, have opted to hedge the forecast to the pessimistic idea for this cycle, to allow planning for a worse outcome. This means enough moisture lingers after today`s rain along with very light to calm winds for development of overnight stratus and/or fog, with MVFR conditions emerging ~04Z around the area. This continues until ~14Z, when we see rapid improvement to VFR conditions. The other option? There`s simply not enough moisture to allow for CIGs/fog to crop up, and we stay VFR through the night. Like the other scenario, winds stay fairly light and variable. Eventually, SE winds will resume, though it may not quite occur in this TAF period. Key thing will be to watch through the evening to see how reality emerges, and will be prepared to match the forecast to the scenario that ends up winning out.

&& .MARINE... Issued at 253 PM CDT Wed Jun 5 2024 Moderate onshore winds and seas should gradually weaken/subside this evening. Surface high pressure centered across the north- central Gulf will continue to provide light to occasionally onshore winds over the Upper TX coast. A weak cold front will attempt to move over the coastal waters tonight into Thursday. No major impacts are expected other than a brief wind shift through midday Thursday. A few showers and storms will be possible offshore during the remainder of the week; however, a general dry trend can be expected through Sunday. The next best chance of showers and storms return late Sunday into early next week as a disturbance and frontal boundary move through. Light to occasionally moderate onshore winds should persist through the week and into the weekend. The risk of strong rip currents continues through the end of the week due to persistent onshore winds. JM && .CLIMATE... Issued at 300 AM CDT Wed Jun 5 2024 Going 5 for 5 would be an OUTSTANDING night for a baseball player...going 5 for 5 on breaking record high minimum temperatures isn`t quite as exciting. On June 4th, all five climate sites either tied or broke their records for high minimum temperatures as we saw widespread low temperatures in the low 80s. - College Station: 80F (tied the record from 1902) - Houston Intercontinental (Bush): 82F (breaks record of 80F from 1998) - Houston/Hobby: 82F (breaks record of 81F from 1998) - Palacios: 82F (breaks record of 80F from 2012) - Galveston: 83F (breaks record of 81F from 2008) Batiste && .PRELIMINARY POINT TEMPS/POPS...
