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.

RIGHT NOW: Flooding is the big concern; scroll down for some late flooding reports; lots of issues across North-Central Alabama this afternoon, with rain totals in the 2 to 4 inch range for many areas. Skywatcher Nathan Jones in Pelham reports they have just reached the 5″ mark for today with over 2″ in the last 40 minutes. Be very, very careful as you drive home this evening; you know the deal… turn around, don’t drown. Periods of rain and thunderstorms will continue through the night, aggravating the flooding situation.

TORNADO WATCH: SPC has issued a tornado watch for parts of Central and West Alabama until 8:00 p.m. Quite frankly, I am not overly impressed with severe weather parameters at this moment. Rain cooled, stable air covers much of the state, and the higher surface based CAPE values are well to the west over West Mississippi, Arkansas, and Louisiana. And, the best helicity values are actually off to the east, over Georgia. Having said that, this is March, and with potent dynamics approaching you always have to watch storms closely that develop in this kind of regime. Seems like the best chance of getting some surface based severe storms will be over Southwest Alabama, in the general area from Demopolis south to Mobile. Severe weather is not expected over the eastern half of Alabama.

TOMORROW: Models are trending toward the idea of rain and storms ending across the state tomorrow morning, with only a small chance of redevelopment tomorrow afternoon. However, if the sun breaks out at midday, and we rise into the 70s, don’t be shocked to see a few scattered showers and storms firing up late in the day, and where they form some hail reports will be possible due to the cold air aloft over Alabama.

FRIDAY AND THE WEEKEND: A deep, large upper low will form north of Alabama Friday, keeping our weather unsettled. Looks like Friday will be a mostly cloudy day, with scattered showers and thunderstorms, and a high around 70 degrees. The NAM is the most aggressive with the rain on Friday, suggesting we could pick up another one inch in spots.

While a few showers are still possible Saturday, they should be fewer in number. Saturday will also be cooler with a high in the mid to upper 50s. And, we will not mention any chance of rain on Sunday with low 60s during the afternoon. We do note a few showers will be possible Sunday afternoon over the far northern part of Alabama where the air will remain unstable.

NEXT WEEK: The 12Z GFS continues the idea of a generally dry week next week for Alabama, with highs mostly in the 60s. An impulse in West Texas Sunday is shunted far to the south over the Gulf of Mexico. So, for now all looks calm next week for most of Alabama, and the Gulf Coast.

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.

LIVE CHAT: We are now offering a real time chat here on the blog… open blog comments will stay in place, of course, but this will allow a more immediate method of communication for weather geeks. We do have moderators posted over there, so be sure and play nice. Members of our weather team will be there from time to time to answer questions; we will post those times we are available here on the blog.

I had a great time today visiting with the kids at Trinity United Methodist Church in Homewood; be looking for them on the Pepsi KIDCAM today at 5:00 on ABC 33/40 News! Stay tuned to the blog for updates this evening… the next Weather Xtreme video will be posted by 7:00 a.m. tomorrow…
