04/15 – Rob Knight’s “Cooler” Wednesday Forecast

A couple of cold mornings in store as Canadian high pressure centered over central Texas and ridging into the Ohio and Allegheny Valleys remains in place through Thursday. Morning lows in the interior portion of the forecast area should settle into the mid-40s.

A resurgence of cold air moving in should limit heating Wednesday, with highs only reaching the upper 60s to lower 70s. This equates to about 10 degrees below normal on both highs and lows for Wednesday. Despite a cold early start for Thursday morning, daytime heating on neutral advection should get daytime highs closer to normal.

Another system drops through the Plains States Friday. This will present some lift and destabilization Friday afternoon for chance showers and thunderstorms. Front moves off the coast Saturday early morning but only gets so far.

A piece of energy ejecting from the desert Southwest and transiting the Southeast comes across Saturday night and Sunday to maintain some elevated base convection.

Surface high pressure eventually digs well into the gulf for a repeat of cooler and drier conditions for early next week.
