9/6 – Rob Knight’s “Labor Day” Morning Forecast
[videoembed][/videoembed]The upper level high-pressure centered along the northern Gulf Coast will continue to move south and weaken. An upper level trough digging across the Mississippi Valley and an associated surface cold front will drop southeast into the forecast area. Showers/T-Storms along the front will begin to impact the area later this morning into tonight.
Deep tropical moisture should be in place with the possibility for isolated pockets of heavy rainfall through mid-week. There will be the potential for several inches of rain to fall quickly in some locations as the very moist conditions should support heavy rainfall rates. The potential is increasing for heavy rainfall and areas of flash flooding over locations that have already experienced excessive rainfall during Hurricane Ida. This will be closely monitored and a flash flood watch may become necessary.
The frontal boundary will stall across southeast Louisiana/S. Mississippi through Tuesday and with building instability again on Tuesday along and south of the front, expecting additional development of numerous showers and thunderstorms across southeast Louisiana.
