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

The great Alabama weather legend, J.B. Elliott, maintains a low of 39 in his forecast for tonight. But, we all know temperatures will be all over the board on a clear, calm night in Alabama due to the radiational cooling effect. The actual range will be from near 33 in the coldest valleys to 48 on the ridge tops. Some scattered light frost is possible in valley locations, but a major, widespread damaging frost is not expected.

We begin a warming trend tomorrow as we climb into the mid 70s, and low 80s are likely on Thursday. Both of these days will be dry with a good supply of sunshine. Conditions will become breezy at times Thursday with a strong southwest flow.

NEXT RAIN: The 12Z GFS is in line with the 00Z run, so it looks like showers and storms will move into Alabama during the day Friday, becoming more widespread Friday night. Looks like the best chance of showers and storms will come from about 3:00 p.m. Friday through 7:00 a.m. Saturday. Rain totals around one inch will be likely, with isolated heavier amounts possible. A major severe weather threat is not likely with the best dynamic support well to the north, and marginal instability values.

WEEKEND PEEK: It now looks like the rain will be over by mid-morning Saturday, with the sky becoming partly sunny Saturday afternoon. We have removed all mention of rain for Sunday as dry air moves into the state. Looks like highs over the weekend will be generally in the 70s.

NEXT WEEK: The 12Z GFS has pushed the best chance of rain back to Wednesday and Thursday; for now Monday and Tuesday look dry and mild.

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 are going to have to wait until tomorrow night to get this week’s new show recorded; it will be available around 10:00 tomorrow night.

I had a great time doing a severe weather safety training session today for employees of McGuffey Health Care in Gadsden… thanks for the hospitality! The next Weather Xtreme video will be posted here by 7:00 a.m. tomorrow….
