5/25 – Night Rob’s “One More Round” Wednesday Evening Forecast

The main concerns are for heavy rain in the first 12-18 hours of the forecast…round one came through this afternoon, with round two overnight into Thursday morning.

Both heavy rain and thunderstorms are on the way, in two distinct batches, with a bout of heavy rain and lightning today/tonight, followed by the actual cold front before and during sunrise Thursday. With moisture values remaining elevated, rainfall amounts over the next 12-18 hours are likely to average in the 3 to 5 inch range across much of the area with spot totals possibly well above that if the system slows down at all.

A Flood Watch for expected Flash Flooding will be in effect for the entire area through Thursday morning, although portions of it could end up being cleared earlier than that, depending on the speed of the frontal passage. Can’t rule out a few strong to severe storms either, but the primary concern should be heavy rainfall. The Thursday morning segment has the slightly higher risk for a severe thunderstorm in the mix.

Once we dry out on Thursday, lower humidity values will move into the area for Friday. This will provide a noticeably-cooler morning on Friday, but with plenty of sunshine, we should still see highs in the mid and possibly upper 80s Friday, but with noticeably less oppressive humidity. High-pressure will move across the area over the weekend into the Ohio River Valley, which will produce easterly flow early next week. Some model solutions indicate a piece of energy working itself westward across the northeast Gulf Coast Tuesday into Wednesday, which could increase chances for precipitation a bit.
