A ridge of high pressure at the surface is dominating much of the southeast from the mid Atlantic coast through coastal Mississippi. Aloft a ridge of high pressure is controlling the weather across the Rio Grande Valley into the Midwest.
Stable air is in place at all levels. The mid and upper levels of the atmosphere are relatively dry, but the surface is moist with dew points in the low to mid 70s. So, hot and humid weather will remain in place with highs in the 90s and the heat index near 95. A few storms may pop up with daytime heating, but the coverage should be 20% or less.
This pattern is expected to remain in place for the rest of the week and most of the weekend. A bit of a breakdown later next week could help to fire up a few more scattered storms during the afternoon hours by Monday and Tuesday.
Today, expect partly cloudy skies with highs in the low 90s. Heat index near 95. Chance for rain 20%.
Tonight, fair skies with some haze and fog developing late. Lows near 74.
Thursday, sun and clouds mixed with a high near 92. Heat index 95. Rain chance 10%.
Friday through Sunday, partly cloudy and hot with highs in the low 90s.
Tropical weather remains quiet through the weekend.
