An all new edition of the ABC 33/40 Weather Xtreme video is available in the player below, and on iTunes…
Dewpoints are on the way up; most places are reporting dewpoints in the 55 to 60 (F) range this afternoon, and that trend toward better low level moisture will continue into the weekend.
We will introduce the chance of widely scattered showers tomorrow afternoon and tomorrow evening, much like a summer day. The best chance of a shower will come from about 2:00 until 7:00 p.m. Nothing really organized, and no severe weather is expected.
OUR WEEKEND: We will have to dodge scattered showers and storms both Saturday and Sunday. A surface front will stall out somewhere around the Tennessee Valley Saturday, and it looks like the most numerous showers and storms during the day will be north of I-20. Even there, the day won’t be a total wash-out. That front will lift slowly northward Sunday in response to a new and stronger system over the nation’s mid-section. We will remain in a rather moist and unstable environment Sunday, so once again we will mention a chance of scattered showers and storms.
It still looks like the greatest chance of strong to severe storms will come Sunday night with a strong front approaching, supported by a deep upper trough. The main window for strong to severe storms will generally be from 6:00 p.m. Sunday through 3:00 a.m. Monday. Looks like many communities will have the chance to pick up about one inch of rain over the weekend, with the heaviest rain coming Sunday night.
RACE WEEKEND: The chance of a shower at the Talladega Superspeedway tomorrow is only about one in five, but the odds will increase to about one in three on Saturday and Sunday. Afternoon highs over the weekend at Talladega will be in the 77 to 80 degree range, with a few intervals of sunshine away from the showers.
NEXT WEEK: The rain should end early in the day Monday, and much cooler air returns to Alabama. The latest MOS is showing a high of 65 for Birmingham Monday, followed by a low of 44 early Tuesday morning.
VOODOO LAND: The GFS (the 12Z run) shows a rather unsettled upper air pattern over Alabama as we get into early May, suggesting occasional rounds of showers and storms, although no major severe weather threat is seen. Not much confidence in this since run to run consistency has not been very good in recent days.
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.
I had a great time speaking to the 3rd graders today at Shades Mountain Christian School in Birmingham… be looking for them on the KIDCAM today at 5:00 on ABC 33/40 News! The next Weather Xtreme video will be posted by 7:00 a.m. tomorrow…
