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.

COOL MORNING: Temperatures are well down in the 50s across much of North Alabama this morning; the community of Meridianville up in the Tennessee Valley near Huntsville reports 49. We won’t have too many more of these before the long hot summer sets in. The cool morning also means dewpoints are low; and that drier air should mean relatively rain-free weather for North Alabama today. Most of the showers that form this afternoon should be over the southern half of the state; some could get as far north as Livingston, Demopolis, and maybe Eutaw in West Alabama, but most places around here will be dry today as the sky becomes partly sunny.

TOMORROW THROUGH FRIDAY: Dewpoints will begin to rise tonight as moist air moves northward, and we will have to bring back the risk of scattered showers and storms statewide tomorrow and Thursday. The best chance will come during the afternoon and evening hours, but a few late night or morning showers can’t be ruled out. We note a major severe weather/tornado outbreak is likely tomorrow from roughly Tulsa to Chicago, with the highest probabilities centered near St. Louis. Could be a dangerous weather event up there.

The weather Friday will remain warm and humid with a chance of showers and storms during the day. Highs will be mostly in the low 80s over the latter half of the week.

WEEKEND PEEK: We expect a gradual increase in the coverage and intensity of showers and storms over the weekend, with the wettest day most likely on Sunday as a surface front approaches from the north. We could be looking at some heavy rain around here before the weekend is over, and maybe a strong or severe storm along the way.

NEXT WEEK: A shot of drier air begins to move into Alabama Monday, and at this point it looks like Monday and Tuesday of next week will be dry for the northern counties of the state.

VOODOO COUNTRY: Late May sure looks like late May on the GFS; the westerlies retreat north, we stay in a warm and muggy airmass, and the chance of diurnal showers and storms will be in the forecast pretty much on a daily basis, which is what you expect as we get close to summer.

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 will be on the road to Jacksonville this morning to see the 4th graders at Kitty Stone Elementary School in Jacksonville; this has been a May tradition for many years. I will be back in the office this afternoon and the next Weather Xtreme video should be posted by 3:30 or so. Enjoy the day…
