&& .SHORT TERM... (This evening through Sunday night) Issued at 129 PM CDT Sat Sep 21 2024 Tonight through Tuesday, conditions will be pretty dry overall, looking at the models, as high pressure continues to build over the area. An isolated shower or two will be possible during peak daytime heating hours over the next few days, but generally, it will be dry and warm. Highs are forecast in the mid 90s with heat index values in the low 100s. While it won`t meet heat advisory criteria, be sure to stay hydrated if you will be outside the next few days as it will be a bit warmer than normal for this time of year. MSW && .LONG TERM... (Monday through Friday night) Issued at 129 PM CDT Sat Sep 21 2024 As we head toward mid-week, there is still a lot of uncertainty in the models and confidence is lower than usual. But in general, by Wednesday, there is the potential for a tropical system to develop in the region by the Yucatan Peninsula. Currently, there is a 60% chance for development in the next 7 days for this disturbance. If it forms, it is expected to move into the Gulf sometime late week. At the same time, a frontal system is expected to move through the area late next week as this ridge moves eastward out of our area. These two systems will be dependent on each other and there are still numerous uncertainties surrounding the timing of the front and how it relates to potential development of a tropical system. It is far too soon to say any specifics or details about the tropical system. And as for the front, expect increased rainfall chances toward the end of the week, regardless. We will be monitoring the potential for tropical development closely over the next week. MSW && .AVIATION... (00Z TAFS) Issued at 635 PM CDT Sat Sep 21 2024 General VFR conditions. Can`t rule out isolated patchy fog around sunrise, but threat isn`t high enough to carry in the forecast for any significant amount of time. && .MARINE... Issued at 129 PM CDT Sat Sep 21 2024 Benign marine conditions expected through Thursday. Winds will be easterly to southeasterly and moderate (10-15kts) through Thursday morning. Starting Thursday, winds increase to 15-25kts and easterly to northeasterly. However, a lot of the late week forecast is still highly uncertain and will be dependent upon the potential for tropical development. The hurricane center has an area outlooked at 60% for tropical development over the next 7 days over the NW Caribbean and southern gulf. Remain updated with future forecasts concerning this area over the next several days. MSW && .PRELIMINARY POINT TEMPS/POPS...
