**No afternoon Weather Xtreme video today… sorry; a road trip, a class ending party, and a conference call have me tied up!**

As expected, isolated storms are forming this afternoon across the Tennessee Valley in advance of a surface cold front. The NWS office in Huntsville has issued severe thunderstorm warnings for those storms; the primary risk will come from hail, and the possibility of strong winds in a few spots.

**A new severe thunderstorm watch has been issued for much of North-Central Alabama because of these developing storms**

These storms will drift southward this evening, but will fizzle out quickly once the sun goes down.

TOMORROW: Drier and slightly cooler air will drop southward into the northern half of the state; it should be a beautiful day with ample sunshine and a high around 80 degrees. We won’t get to use the words “less humid” that often during the next three months.

THURSDAY AND FRIDAY: Moist air moves northward again, and we will mention the chance of scattered showers and thunderstorms on these days, mainly during the afternoon and evening hours. Otherwise, we will forecast a mix of sun and clouds with a high in the low to mid 80s.

MEMORIAL DAY WEEKEND: Looks like we will need to hang on to a chance of scattered showers and storms on Saturday, but Sunday and Monday should be generally dry with the upper high building overhead.

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 will record a new show tonight… it should be posted by 10:00 or so.

Thanks to everyone at Mt. Zion Baptist Church in Calhoun County for their hospitality… I sure enjoyed the visit today. The next Weather Xtreme video will be posted by 7:00 a.m…. and J.B. Elliott will have storm updates for the rest of the afternoon….
