Winds will remain out of the south today. The increase of low level moisture and warmth will lead to another mainly cloudy day with highs in the upper 70s! The record high for today is 81°, that's just how unseasonably warm it is. With a bit more instability today versus yesterday, some showers will also be possible. I expect rain chances to dwindle overnight and for the first part of Saturday before a much more organized system makes its way into the region.
An upper level trough will interact with a surface front across Texas forming a second low pressure system and cold front that will move through Southeastern Louisiana Saturday Evening. Along and ahead of this cold front, strong to severe thunderstorms will be possible.
Timing: Saturday Evening - Sunday Morning
Best Chance for T-Storms: Saturday Night
Potential Threats: Squall Line with gusty winds, heavy downpours, an isolated tornado
This of course may make regional travel difficult during that Saturday Evening to Sunday Morning time frame. Roadways will be wet and with turbulent thunderstorms there could also be some flight delays. Check the forecast and your travel itinerary before heading out the door.
