6/24 – The Chief’s “Dangerous Heat” Monday Morning Forecast

The main story today will be the heat as high pressure continues to spread eastward along the Gulf Coast today. Low level moisture will be on the increase today as well, which coupled with the hot afternoon temperatures will lead to heat index values to climb into the 108-110 F range. That said, there could be some late afternoon relief in the form of isolated to scattered showers and thunderstorms, however, subsidence should keep most of this activity low-topped and rather low in coverage. Outside of the heat advisory for much of the region, wanted to focus on another Coastal Flood Advisory for coastal Hancock Co.

If we get a little rain tonight, some shallow ground fog may be possible. Outside of the rain and wet grounds, there could be some moisture pooling along a weak surface boundary that will move in and stall across the region later this evening before it begins to dissipate.

On Wednesday, more numerous showers and thunderstorms are anticipated as another surface boundary and parent upper level disturbance begins to slide southward on the eastern periphery of the high pressure across the Southwest U.S. This will likely help keep the heat in check slightly (it will still be hot, but largely not advisory hot). This weak surface boundary does stall across the Gulf Coast region and with a series of upper level impulses likely to interact with peak daytime heating.
