We are stuck in a surface pattern where an old cold front has become stationary along the northern Gulf as the upper level flow is parallel to the front. Several fast moving upper disturbances are embedded in this flow triggering rounds of heavy rains. One such disturbance is drenching areas from Baton Rouge eastward across the North Shore into Mississippi.
This boundary is unlikely to move much until that upper low back over the Rio Grande kicks east of us by Monday. It's hard to find the boundary with temperatures as there is no cold air north of it. The dew points are slightly lower, but not by much.
It's pretty obvious on the infrared color satellite view where the current upper disturbance is located.
Not only do we have heavy rainfall, but lots of vivid lightning.
At 2 PM, If you don't have to travel on the North Shore during the next 3-4 hours, it's best you stay home. It appears this band of heavy rainfall will slowly shift to the southeast but it's likely to leave behind many flooded roadways. The South Shore will need to pay attention later this evening if the band holds together.
Make sure your cell phone is nearby in case warnings are issued by NWS. Check with FOX 8 at 4 & 5 PM for the latest weather information.
We will not see the rain threat leave until early Monday morning. Just keeping checking the radar on your FOX 8 weather app & use common sense. Try to enjoy what appears to be a semi-soggy weekend.
