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.

DUAL FLOODING/SEVERE WEATHER THREAT: After a series of beautiful spring days, our weather will be increasingly wet and stormy during the latter half of the week.

TODAY AND TOMORROW: Nice weather continues with highs well up in the 70s today and tomorrow. The sky will be partly sunny, and a few isolated showers could show up tomorrow, but most places will stay dry.

TO THE WEST: Be sure and watch the Weather Xtreme video for the details; there is a moderate risk of severe weather today for the area roughly from Oklahoma City to Wichita, with a larger slight risk surrounding that from Texas to Minnesota. Strong to severe storms will break out across this region this afternoon and tonight, and the risk continues tomorrow from Dallas/Fort Worth to Jackson. We will be watching these developments closely.

RAIN MOVES IN HERE WEDNESDAY: We will forecast a good chance of rain and thunderstorms Wednesday, but for now the risk of organized severe weather looks small as the dynamics will weaken and lift well to the north of Alabama. Lapse rates and instability values are also marginal for severe storms. The initial problem here will come from heavy rain and the flooding potential, since the front will stall out somewhere over Central Alabama. We note the guys at HPC suggest five inches of rain are likely for the I-20 corridor through Friday evening.

THURSDAY: With the stalled front around, rain is likely, and possibly some thunder, but no severe weather is expected.

FRIDAY/SATURDAY: A strong upper trough will come out of the Rockies, and our front will try to slowly move northward as a warm front. This, of course, means more rain for areas north of the front, and it also means much of the state will get into the large warm sector of this system, with high surface based CAPE values (over 1,500 j/kg). The stage is set for an outbreak of severe thunderstorms here in Alabama at some point; the most likely time seems Friday night and Saturday. Based on the projected shear and instability, it would be a significant threat, but it is way to early to really be specific. We will know much more as the week progresses.

SUNDAY/MONDAY: Colder air invades Alabama Saturday night and Sunday following the stormy period; we might be looking at some potential for frost or a light freeze by Monday of next week. Again, we will fine tune that potential as we go along this week.

VOODOO COUNTRY: Another decent looking storm setup shows up on the GFS around April 3… see the Weather Xtreme video for details.

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. Just a reminder, we are producing the show on Tuesday nights during the rest of the spring, so the new episode for this week won’t be posted until tomorrow night.

TWITTER: Don’t forget, you can follow our news and weather updates from ABC 33/40 on Twitter here. And, my personal Twitter feed is here if you want to keep up with my adventures in life. Twitter is a short messaging service you can receive via the web, cell phone, or IM.
