An all new edition of the ABC 33/40 Weather Xtreme video is available in the player below. You can subscribe to the Weather Xtreme video on iTunes by clicking here.
ONLY ISOLATED SHOWERS: The upper ridge over the eastern U.S. will be very slow to break down, and accordingly our weather won’t change too much for the rest of the week and the coming weekend. Temperatures will remain above average, with daily highs mostly in the 80 to 85 degree range. Moisture will increase sufficiently for the chance of “widely scattered afternoon showers” on a daily basis through the rest of the week and the weekend, but the better dynamic forcing will remain to the west and north of Alabama. Another words, a very summer-like pattern.
Like a summer day, the best chance of anyone seeing a shower will come during the peak of the daytime heating process, which helps air parcels to become buoyant. Mesoscale features will be involved in the best coverage of the showers, but generally speaking, the better coverage will be close to the Tennessee border, and hardly any will be found south of Birmingham. Otherwise, the days will be partly sunny with mostly fair nights.
NEXT WEEK: The 00Z GFS doesn’t offer much hope for really widespread rain next week. The idea of a deep upper trough west of here with a disturbed southwest flow is gone, and it looks more like June with a muggy airmass in place and the daily risk of a few scattered afternoon showers. Temperatures will remain above average values for early May with highs in the low to mid 80s.
VOODOO LAND: Watch the Weather Xtreme video and you will see the GFS moves the upper ridge over to the Southwest U.S. around May 11, with a deep upper trough over the east. Even a tropical storm at the same time near the western tip of Cuba (which, most likely, is totally bogus). Maybe at some point during that transition we will pick up some decent rain; we really need several more good rain events before we get into the summer months. Birmingham will slip into a rain deficiency for the year today.
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. We will record a few episode tonight; it should be posted by 10:30.
