Check out that amazing wall cloud picture on the video today... amazing stuff.
We have seen a few echoes on radar over north Alabama today, but nothing has reached the ground as far as we know. We will leave the forecast dry and tonight and tomorrow. Winds will really pick up tomorrow out of the south, gusting to 30 mph at times. We will have a few intervals of sunshine, and temperatures should reach the low 80s tomorrow afternoon.
STORM SITUATION: Not much change in our thinking on the next storm event. A long squall line should race through Alabama sometime between midnight tomorrow night and 6:00 a.m. Saturday with the potential for widespread wind damage. If we happen to get a few discrete cell ahead of the line, a few isolated tornadoes are not out of the question, especially over northwest Alabama. SPC has now placed much of north Mississippi, western Tennessee, and northeast Louisiana under a moderate risk of severe storms for tomorrow evening and tomorrow night. This is where a few damaging tornadoes will be possible.
Here are the latest severe weather parameters for us as they peak between midnight and 6:00 a.m. Saturday:
SB CAPE 945
Lifted Index -2.4
0 to 3 km Helicity 427
2M AGL Dewpoint: 66
SWEAT Index: 360
850 mb winds: 59 knots
500 mb winds: 53 knots
Not much change in our thinking. Severe storms and isolated tornadoes will form to the west late tomorrow, with the thunderstorms evolving into a squall line that will race through Alabama. It won't take much to get those 850 mb winds (around 5,000 feet off the surface) down to the surface, and a number of segments within the line could produce winds to 70 mph or greater.
Everyone will need to have a good way of hearing severe weather warnings during the pre-dawn hours on Saturday.
Interesting to note how the forecast rain totals keep coming down; the NAM now only showing about one-third of an inch of rain with the storms early Saturday morning. The storms will simply be moving so quickly we won't see all that much rain. We might even get in the little league baseball games on Saturday!
REST OF THE WEEKEND: The storms will end early Saturday morning, with the sky becoming partly sunny. We have lowered afternoon forecast temperatures into the 60s. The day will also feature a brisk northwest wind from 12 to 22 mph.
Sunday should be a very nice day with ample sunshine and high temperatures in the 70s.
NEXT WEEK: Looks wet at times Tuesday through Thursday. Will fine tune this as we get closer...
Enjoyed speaking to a big group of retired physicians at St. Vincent's Hospital today...
