.DISCUSSION...

A reinforcement of cold and dry air will move across the area
over the next couple days. It`s not until Wednesday that onshore
flow brings increasing moisture back to the region.
No significant precipitation is expected until Wednesday night or
Thursday at soonest. A more humid and rainy pattern will then
persist into the weekend as a series of fast moving storm systems
moves through the Gulf South.
