Updated at 459 AM CDT Mon Jun 8 2026 - A more pronounced drying trend will begin today, with less shower and thunderstorm activity for much of the week. - Further slow easing of tide levels is expected over the next few days. && .SHORT TERM... (Now through Thursday) Issued at 1023 PM CDT Sun Jun 7 2026 Some measurements of rainfall over the last several weeks have been in feet with no one coming out of this period with no rain. We will now move into a relatively dry period with only isolated to scattered activity on any given day through this week. The trade off is heat. As the clouds and rain leave, the heat begins to take over again and this time it will have plenty of moisture to evaporate into the boundary layer making it feel somewhat uncomfortable during the hottest part of the day. I use the word uncomfortable and not miserable because the one thing that will help is the column will be ventilated each day as there will be no strong cap available to keep mixing down, we are just getting some drier air moving in to lower the rain chances. The weak cap and mixing during the hottest part of the day will help keep high heat index values relatively low in the mid to upper 90s each day through Thursday, but this will change once a stronger cap moves in and mixing values weaken possibly by the end of the work week, but this is looking short lived. && .LONG TERM... (Thursday night through Sunday) Issued at 1023 PM CDT Sun Jun 7 2026 Upper ridging will be centered near the Sabine River Thursday night, with a strong shortwave trough moving into the western Great Lakes. At the surface, the Bermuda high will extend across much of the Gulf, while a frontal boundary extends from Ohio to west Texas. By Sunday, the upper ridge axis will retreat westward to near El Paso, although it will still exert influence across the local area. The frontal system to the north looks like it will never reach our area. That shouldn`t be a surprise at this point, as we`re reaching the time of year where frontal passages become uncommon for a few months. Moisture levels by the time we get to Thursday night and Friday will be somewhere around the 50th to 75th percentile, around 1.6 inches. Low level southerly flow won`t really plug in until late Saturday or Sunday. Sunday values will exceed 2 inches by late afternoon, and be near the daily max across some portions of the area. With no strong synoptic features to focus rainfall, the daily diurnal cycle will drive convection, beginning to fire around midday, generally along lake and sea breeze boundaries, propagating on outflows. At present, NBM PoPs appear to be on the high side, by perhaps 10 to 20 percent for at least Friday and Saturday (currently showing 40-60 percent). Little day to day change in temperatures with highs generally in the lower 90s and lows in the 70s. That`s a few degrees above normal, but not terribly unusual in June. && .AVIATION... (12Z TAFS) Issued at 459 AM CDT Mon Jun 8 2026 A mix of MVFR and VFR cigs will remain through sunrise before becoming all VFR for the day. Some MVFR cigs could be found along the immediate coast tonight but most terminals will be VFR through tonight as well. Chances of RA or TSRA over any one terminal is not high enough to show in this taf cycle finally so the only thing that would cause anything lower than VFR will be cigs. && .MARINE... Issued at 1023 PM CDT Sun Jun 7 2026 For the remainder of this week, winds should remain ESE to SE at 10 to 15 knots. The number of showers and storms around will decrease quite a bit today and hold that pattern through the remainder of the week as well. Winds and seas will be higher in and near any thunderstorm activity that does occur. && .LIX WATCHES/WARNINGS/ADVISORIES... LA...None. GM...None. MS...None.
