Today: There is no significant weather pattern influencing our weather, so I expect a typical summertime pattern today. Highs will be near 92 degrees with heat index values between 105 and 108 degrees. This will lead to heat illness concerns again. A Heat Advisory will not be issued but it depends on the timing and coverage of afternoon storms. They are expected to be scattered this afternoon to evening. Otherwise, we will see partly cloudy skies during the day with mostly clear conditions tonight with overnight lows around 75 degrees. We’ll keep 75 degrees for an overnight low pretty much every day this week.
Tuesday: We’ll see spotty storms with slightly less coverage tomorrow. The reason for this is a high-pressure system extending from the northern Gulf to the Carolinas will nudge westward, reducing the amount of moisture in the air, making it slightly tougher for storms to develop. Highs will be near 93.
Wednesday: The high-pressure system to the east will continue to nudge west into Wednesday, leading to a mostly dry day where heat will be the primary concern. Isolated afternoon storms will still be possible. Highs will be near 93.
Thursday-Friday: Rain coverage will slowly increase each day as a disturbance will kick the high-pressure system back east, increasing the moisture available for thunderstorm development. Highs will be near 92.
Weekend: Scattered to numerous storms are expected as a disturbance swings near Louisiana increasing both instability and moisture for showers and thunderstorms to grow. Highs will e in the low-90s.
Tracking the Tropics: There are two systems of possible development heading into Caribbean waters soon. One has a low chance of development, the other has a moderate chance of development in 48 hours. I will be watching this closely for you as it look likely to form near the Greater Antilles.
