At the surface, the remnant of a very weak frontal boundary is lingering along the Mississippi coast. High pressure over the Canadian Prairie Provinces extends southeast into the middle Mississippi River Valley.
Expect another 36 hours of relatively quiet and dry weather, albeit hot for most of the area. Similar to the last couple of days, any convection today should remain rather isolated and primarily near the coast. As we get into Saturday, moisture levels will begin to increase. Coverage of convection should increase to 30-40 percent by late Saturday afternoon, and to 40 to 60 percent Sunday afternoon as the base of the weak upper trough becomes more located over the local area.
An approaching cold front will gain a little more amplitude by Monday and Tuesday, which will mean precip chances in the likely range for much of the area, primarily during the daytime hours from Monday afternoon into Wednesday morning before the airmass starts drying out from the northwest.
This will be short-lived as another piece of energy drops into the base of the upper trough on Friday. With the additional precipitation/cloud cover, high temperatures should drop back to around 90, or even into the 80s beginning Monday and continuing through much of the workweek.
