We will see several cold fronts push through during the week ahead keeping winds west to northwest at the surface. In the middle and upper levels we maintain a mostly southwest flow keeping the cloudy sky around.
A few showers linger through mid-day, but stronger storms will pick up again for the evening and overnight. The Storm Prediction Center keeps southeast Louisiana and the Mississippi Gulf Coast in the lowest level marginal risk for severe storms.
Expect clouds to lower and thicken through the overnight and a low pressure system will push across the area from the west keeping our region in the warm sector of the storm system through Thursday evening.
A freeze warning goes into effect for areas away from the water and north of Lake Pontchartrain. We will also see widespread frost likely everywhere outside of the immediate metro area.
The cold holds on through Tuesday with a light freeze/frost for most locations away from the city on Wednesday morning. Wednesday afternoon a warm up begins and more moisture moves into the region.
An area of low pressure sliding across the Gulf of Mexico will push moisture north across the central Gulf Coast. Very dry conditions are in place at the surface with dewpoints in the low 40s so while it will be cloudy through the day the showers will likely hold off until the later part of the afternoon.
Clouds will stick around because upper winds are becoming parallel to the front allowing the boundary to stall just offshore. This will keep us cloudy with a chance for showers returning for the Thanksgiving holiday.
A few storms will meet the severe criteria with winds gusting near 60 mph, brief heavy rain and hail with the chance for tornados. Timing allows for a few storms moving through during the evening hours building from the northwest.
