4/28 – Rob Knight’s “Humidity Moving Back In” Thursday Afternoon Forecast
At the surface, high pressure extended from the Great Lakes southward to Florida will shift slowly eastward over the next few days, to be centered near the Appalachians by Saturday evening. Upper level weakness currently moving on the Pacific Coast will move eastward to Iowa by Saturday. An associated low pressure center at the surface will develop over Colorado today, and move to Iowa Saturday.
While winds gradually come around from northeast today to southeast on Friday, moisture levels will be on the increase. We could see a few showers or a thunderstorm along the Mississippi coast this weekend.
If we are going to see any significant precipitation over the next seven days, the “best” opportunity for it appears to be Sunday afternoon. Not exactly confident on that possibility either, as the storm system in Iowa on Saturday lifts into Canada. The associated cold front never really gets close to the local area, but with daytime heating, a little more activity could develop along the coastal counties. Temperatures will be above normal for early may for all of next week.
