.SHORT TERM...
/Updated at 0624 PM CDT Thu Mar 25 2021/

Long track damaging tornadoes have moved across Central Alabama
this afternoon. Significant damage has taken place. At this
writing, no tornado warnings are in effect. A Tornado Watch
remains in effect until 8 pm and may be extended.

So what now, a warm front was located just north of the area while
a cold front/trough was still back to the west. The latest RAP
analysis has SBCAPE values still over 2000 and will become even
more suppressed to the southern reaches the next few hours. A
rain induced boundary or axis of a mixed up atmosphere was west to
east across Central Alabama from TCL to ANB. SRH values will
slowly go down as the low level jet exits northward. So at this
time, it appears the greatest threat will reside south of a line
from Sumter County to Randolph County. The threat north of this
area is certainly not zero, and will keep a mention of severe
storms including tornadoes, but the threat is lower than earlier
this afternoon. So will make some changes to the graphics suite
but the overall trend in the forecast looks ok.

Previous short-term discussion:
/Updated at 450 AM CDT Thu Mar 25 2021/
Today through Friday.

So far this AM we have had widespread showers with embedded
thunderstorms as it spread NE across C AL. The activity has been
elevated and while we are watching for any rogue storms, severe
activity during the early morning hours should be marginal at
best until the warm front makes its way northward later today. We
have increased the severe threat in the NW half of C AL for this
afternoon and evening. This probably doesn't come as much of a
surprise as this system is ramping up to be significant there with
strong tornadoes a possibility. The SE half of C AL is a
different story. While we have a marginal threat this AM for
portions of C AL, for the rest of the afternoon and evening,
parameters are much lower in the SE counties with convection not
as likely there until later this evening. After the current
convection currently on the radar pushes N, we should have a
somewhat lull in activity in the SE.

In contrast, by around 11am, our warm front should be to the N of
the area. Models suggest some cellular activity will likely pop
up in the NW first. MUCAPE will not be lacking, but will be
highest in the west for this afternoon. 0-6km bulk shear will be
in ample supply across C AL. However, 0-1km shear will be
decidedly higher in the NW. Although amounts vary, guidance is in
agreement decreasing this low level shear significantly after 6z
as the bulk of the instability skirts to the NE. This will be not
only with the front moving across, but our negatively tilted upper
shortwave that is expected to be over the Arklatex ~18z today
expected to race off toward IL/IN by midnight tonight. With the
bulk of the activity in the SE counties expected for later this
evening, this greatly decreases the chance for severe weather for
them S of the I85 corridor. This is the reason for the sharp risk
gradient in our severe graphics. Timing is pretty similar to what
we had yesterday except possibly starting in the NW at 11am
instead of noon. The front is expected to make progress after
midnight with the risk for TS in the SE counties much lower for
the day on Friday with lower dew points moving in behind the
front.

.LONG TERM...
/Updated at 450 AM CDT Thu Mar 25 2021/
Friday night through Wednesday.

Rain chances should be minimal for Friday evening but increase
after midnight into the pre-dawn hours on Saturday with some
thunderstorms possible in the NW with shortwave activity. Rain
chances increase once again for Saturday into Sunday with the
approach of another frontal system number 2. However, the upper
dynamics still need to be worked out. The upper setup does not
show a negatively tilted system like front 1. However, we will
have warm and moist air waiting for this springtime front. While
some strong storms cannot be ruled out, will hold off adding
severe just yet with the weekend system. Extended guidance
diverges on timing and strength of the upper low/shortwave behind
the front for Mon/Tue time frame, so only going with low pops for
now. A third front approaches by end of the extended by Wednesday
with elevated shower and thunderstorm chances returning.

.AVIATION...
00Z TAF Discussion.

Showers and thunderstorms will still affect the terminals the next
several hours until a cold front/trough moves through. Until then,
showers and thunderstorms with gradually lowering ceilings. It
appears the general trend will be for the ceilings to hold in the
MVFR range at 015-030. Winds will also be gusty at times even
outside convection. Low level winds will eventually lift north of
the area, reducing any LLWs and wind gusts. The northern terminals
will eventually become VFR by 15-18z while some clouds may hold on
near TOI and MGM. As the surface boundary moves through, winds
will go from south to west northwest.

75

&&

.FIRE WEATHER...

A moist air mass with high relative humidity values will develop
and continue through the weekend with multiple episodes of showers
and thunderstorms. A warm front will lift northward today and
produce numerous showers and a few thunderstorms. Southerly winds
will increase to 10 to 15 mph with higher gusts today as a strong
storm system approaches from the west. There is risk of severe
thunderstorms with tornadoes this afternoon and evening. Rain
chances are lower on Friday, but more showers and thunderstorms
are expected for over the weekend.
