3/26/11 Deep South Severe Weather Outbreak ?
From James Spann

Quote:SEVERE WEATHER THREAT: Parameters continue to look more impressive for severe weather across Alabama Saturday afternoon into Saturday night with very good instability, strong wind fields, and a degree of helicity. While a shower is possible Saturday morning, it looks like the prime severe weather threat will come from 2:00 p.m. through the late night hours. Watch the Weather Xtreme video and you will see that the forecast STP values from the NAM (significant tornado parameter) are over 7 units, which is extremely significant. SPC maintains the standard slight risk of severe weather for the northern half of Alabama; don’t be surprised if that is upgraded to a moderate risk at some point. If the sun peeks out, we might be close to 80 in spots Saturday afternoon, adding to the instability.
