5/11 – Rob Martin’s “Some Rain On The Way” Wednesday Night Forecast

Today was likely the peak of the hotter temperatures, but Thursday will come close. We drop into the upper 60s tonight with a not-too-humid feel to the air. Cooler spots in Jackson County will come in a few degrees lower.

An upper-level low currently in the western Atlantic will move eastward into the east coast of Florida and Georgia over the next few days. At the same time, an upper level disturbance will swing northeast across the High Plains. As both of those systems move, our high pressure system over the area will be getting squeezed north. Losing the sinking air from that high pressure will allow for some afternoon t-storms to start developing Thursday, as rising air will begin dominating in the afternoons. Coverage starts out in the 30-40%, topping out closer to 50% by Saturday. A good deal of surface heating may result in gusty winds with the strongest storms of any given day through Saturday. Most, if not all storms, should stay sub-severe. But, this should result in some beneficial rain, as we’re running about 8″ below-normal rainfall for the calendar year.

We’re likely to have lingering t-storms across the area Friday evening as we lose surface heating. This pattern of morning showers and then isolated to scattered afternoon t-storms will continue through the weekend, although the setup will start to weaken Sunday.
High pressure builds back in early next week and temperatures will go back up.
