Scroll down for the latest on the ongoing weather… the current storms are mostly elevated, and will continue to weaken. Our attention turns to the situation later today.
MODERATE RISK: A moderate risk is up for much of North and Northeast Alabama for today, including places like Birmingham, Cullman, and Gadsden. A slight risk surrounds this all the way from the Mississippi River to the Atlantic Coast.
Watch the Weather Xtreme video and you can see a number of composite severe weather indices are running at very high values later today, including the STP (significant tornado parameter), and CB Sig Svr (Craven/Brooks significant severe weather index), and the 0 to 1 km EHI (energy helicity index).
Quick peek at severe weather parameters from the 00Z run of the NAM:
CAPE: 2521 j/kg
Lifted index: -7.1
Significant tornado parameter (STP): 7.36
0 to 1 km energy helicity index (EHI): 3.17
Craven/Brooks significant severe weather index: 84,199
With no convective mass to the south to block inflow, it sure looks like a very active day for the northern half of the state. All modes of severe weather are possible, including tornadoes. The main window for severe storms will come from about 11:00 a.m. until 6:00 p.m. More than likely, the storms won’t be linear, they will be separated, with good potential for rotating updrafts. As always, today will be a good day to be very close to a good source of weather information.
The storms will move out of the state tonight.
EASTER WEEKEND: While some clouds could hang around tomorrow morning, we expect clearing during the day, with sunshine by afternoon with a high in the mid to upper 60s. Easter Sunday looks nice with ample sunshine and a high in the mid 70s.
MORE STORMS MONDAY: Another very dynamic system sweeps in here Monday with potential for strong to severe storms; SPC has all of Alabama in a severe weather risk. We will fine tune this over the weekend to see if instability values will rise enough for a significant threat. The GFS hints a Gulf Coast MCS could disrupt the inflow of unstable air in here; but that remains to be seen.
Tuesday and Wednesday of next week look dry and pleasant, but rain and storms will return Thursday.
