The upper and surface low pressures that have brought rainfall to the area are currently passing through and quickly racing east. Radar depicts this as well, with only scattered light showers on the scope and even those are trying exit the area.
It may take until mid-morning for all the rain to diminish, but it shouldn’t be too long after that. The rest of the day should be should be relatively dreary with overcast skies. Based on that, plus cold air advection developing as the surface low moves east and high pressure builds in, temps will be much colder than yesterday.
Friday will be much the same with highs in the mid to upper 60s as the region remains under troughing. A reinforcing front Friday night will bring even colder temps to the area Saturday morning.
An upper level high-pressure will quickly pass over the Gulf Coast Saturday into Sunday. Temperatures will respond Sunday and Monday, moderating back into the 70s. A disturbance following on the heels of the ridge will be bringing the return of rain chances Monday afternoon through Tuesday morning.
The bulk of instability and shear will remain north of the area. I’m only expecting a few showers with decreasing coverage from north to south. High pressure will try to build in mid-week, moderating temps slightly.
