6/11 – Trey Tonnessen’s “Lower Humidity” Tuesday Evening Forecast

Meteorologist Trey Tonnessen

At the surface, a frontal boundary was noted south of Lake Pontchartrain, generally south of the Interstate 10 corridor. Quite a spread in moisture values either side of the front, with precipitable water values as high as 2 inches south of the boundary, and 1 inch around Jackson. Scattered thunderstorms were noted on satellite and radar near the front over the Louisiana coastal parishes this afternoon. These storms weren`t moving much, so there will be a few locations getting very heavy rain, with most areas dry. Temperatures at 3 PM away from thunderstorms were generally in the upper 80s and lower 90s, but dew points ranged from the lower 60s well north of the front over southwest Mississippi to mid 70s near the Louisiana coastline.
