Humidity Levels Rise

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player below, and on iTunes…

DEWPOINT WATCH: Dry air still covers North Alabama this morning; the dewpoint at Muscle Shoals is only 49. Birmingham is reporting a dewpoint of 50, but to the south the dewpoint at Mobile is 67. Looks like the northward surge of moist air is a little slower than expected, and accordingly the best chance of a shower or storm this afternoon most likely will be over the southern half of the state. But, the old surface boundary will be moving northward today as a warm front, and that might trigger a few widely scattered showers or storms over North Alabama. Otherwise, the day will be partly sunny with a high in the mid 80s.

TOMORROW AND THE MEMORIAL DAY WEEKEND: Scattered showers and storms are possible statewide tomorrow with a mix of sun and clouds and a high in the mid to upper 80s. Once again, the best coverage will be south of Montgomery. Then, over the weekend, an upper air high will build across the Deep South meaning increasing amounts of sunshine and fewer showers. By the time we get to Sunday and Monday it looks like the state will be pretty much dry. The weather stays warm with highs in the 80s. The latest GFS pushes us into the upper 80s Sunday and Monday.

The weather should stay dry into the middle part of next week with the upper ridge in place.

AT THE BEACH: That QPF graphic sure looks scary (see it on the Weather Xtreme video) if you are beach bound, but I think that is too aggressive. No doubt there will be scattered showers and storms each day along the Gulf coast through Saturday, but there will be some good intervals of sunshine away from the showers (about 4 to 7 hours of sun each day). The central Gulf coast looks dry Sunday and Monday as the upper ridge takes over. Daily highs along the immediate coast will be close to 80, with mid to upper 80s inland. The sea water temperature at the Dauphin Island Sea Lab is 78 degrees as I write this update early this morning.

VOODOO LAND: The 00Z GFS still wants to develop a tropical system in the Northwest Caribbean around the first of June; this run takes it northeast into the Atlantic. Then, a nice upper trough pushes a cold front into Alabama around June 6 with a good rain event. Don’t be surprised if that disappears on the next run.

WEATHER BRAINS: Don’t forget you can listen to our weekly 30 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. You can even listen here on the blog; look for the player on the top left.

Look for the next Weather Xtreme video here by 3:30 this afternoon… enjoy the day!
