Area Forecast Discussion

900 PM CST Wed Feb 5 2020

.UPDATE...
MESOSCALE UPDATE.

&&

.SHORT TERM...
/Updated at 0827 PM CST Wed Feb 05 2020/

The Tornado Watch for parts of Central Alabama has been canceled.
But please take note, the severe threat for the overnight hours
is not over. We will maintain a risk for damaging winds, flooding
rains, and an isolated tornado through 10 am Thursday morning.

We are in a lull right now concerning the intensity of the storms
over Central Alabama. Showers and storms developed over southern
areas much more than originally anticipated, shunting the
potential instability. Additionally, the upper wave that enhanced
the convection has moved northward and was into the lower Ohio
Valley. Therefore, surface based storms are limited at best. There
remains plenty of low level helicity and overall shear.

Another potent wave is visible on the latest satellite imagery
moving over far southern Texas and pivoting our way. This feature
should significantly increase the low level winds and allow a
surface low along the front. As this low develops and moves north
northeast, the upper trough will push the front eastward. With all
this said, an increase in convective strength is expected after
midnight. The main challenge is how far north the threat will
extent with the next wave. We are advertising an area south of a
Demopolis to Roanoke for the best chance, but some threat remains
for the entire area. The threat should end as the wave exits
northward on Thursday morning.

Due to the enhancement of the convection late tonight, the Flash
Flood Watch will remain in effect. Parts of Central Alabama are
still on target to reach the 2-4 inch rainfall amounts range.

Previous short-term discussion:
/Updated at 1208 PM CST Wed Feb 05 2020/
Today through Thursday afternoon.

We continue to highlight a risk of strong to severe storms later
this afternoon, through the overnight hours and into Thursday
morning as a storm system moves from west to east across the area.
The strongest storms will be capable of producing damaging winds
to 60 mph, small hail and a few tornadoes. Additionally, a
prolonged period of moderate to heavy rain coupled with recent
moist ground conditions will support localized flash flooding,
especially in urbanized, low-lying and poor drainage areas.

At this time, the morning showers and storms across our northwest
have quickly lifted north into the Tennessee Valley while a
relative lull was in place across much of our forecast area.
Deeper convection was ongoing along the Central Gulf Coast region
and expect this activity to continue to push northeast into our
southern and southeast counties later this afternoon and into
early evening.

Expect the surface low over Louisiana to ride northeast along the
stationary front this afternoon while a series of impulses aloft
move across the area from the southwest. The better forcing and
dynamics will be in close proximity to the surface low lifting
northeast out of Mississippi later this afternoon and into the
evening across our western counties, however, the extent and
magnitude of this risk is highly dependent on available
instability which may be hampered to an extent by the ongoing deep
convection to our south.

This evening and overnight expect upper level forcing and support
to increase as the upper trough approaches from the west and more
organized convection is forecast to our west, gradually becoming
more linear with time over Mississippi and approaching the area
from the west as we move through the overnight hours and into
Thursday morning.

With the forced linear convection and potential isolated
convection ahead of it progressing east with time Thursday
morning, expect higher instability values potentially to reside
across our southern and southeast counties where the potential
will be best for the stronger activity. Again, the extent and
magnitude of severe weather potential will largely be governed by
the available instability. The dynamical forcing and support will
be favorable for severe weather as the Low Level Jet develops this
evening and intensifies overnight through Thursday morning as it
pushes east across our central and eastern counties.

Southerly low-level winds will become southwest later tonight and
into the day Thursday followed by a more abrupt shift to the west
and eventually northwest as a cold front arrives and pushes east
across the area. With few breaks in the clouds expected, the
destabilization will largely be dictated by low-level warm air
advection and continued positive moisture advection from the south
while height falls and cooling aloft will result as the upper
level trough nears from the west. The instability realization
remains the primary uncertainty in the forecast as overall the
area will be in a favorable position with wind shear, jet
structures in the low, mid and upper levels and forcing with
steepening lapse rates aloft with the approach of the upper
trough.

Convection will gradually taper off from west to east through the
morning hours Thursday as cooler air filters in from the
northwest. Lingering low clouds with rain showers are expected
across much of the area through midday Thursday as drier air aloft
will be slow to arrive behind the departing trough as it takes on
a more negative tilt and swings northeast over the Carolinas into
the Mid Atlantic Region.

05

.LONG TERM...
/Updated at 320 AM CST Wed Feb 05 2020/
Thursday Night through Through Tuesday.

As we progress into Thursday night the system will begin to exit the
area. Still going to have some lingering rain that will be occurring
post-frontal, with the best chances in the east through the
overnight hours. Rain will be shifting east through the night and
should exit the region by sunrise. Will keep precipitation as liquid
through the period.

Colder and dry on Friday with the wrap around cloud cover from the
upper level system moving through. The next system will move quickly
into the region on Saturday and bring a chance of rain by the
afternoon and into the evening hours. This system moves out and then
the next system moves in Monday from the west as a front, but will
stall out by Tuesday morning across the north, before lifting slowly
northward on Tuesday. Models are indicating that this front may sit
across the north for several days and may become a flooding issue
here. Much more on this as the system draws closer. Lows will be in
the 30s and 40s through the weekend and then the 40s and 50s by
Monday and Tuesday.  Highs will be in the 50s to low 60s through the
weekend and then the 60s and 70s by Tuesday.

.AVIATION...
00Z TAF Discussion.

Areas of showers and thunderstorms will continue across Central
Alabama ahead of and along a surface cold front. MVFR cigs should
lower to IFR as the night progresses ahead of the front. A few
strong storms with gusty winds are not to be ruled out. Winds
will shift in the west in the pre-dawn hours behind the front with
the east shifting by around midday Thursday. However, cigs will
remain IFR behind the front with post frontal rain expected.

08

&&

.FIRE WEATHER...

Rain and thunderstorm chances will increase this afternoon and
evening with some strong to severe storms possible. Additionally,
locally heavy rainfall may result in some areas. This system will
affect the area through tomorrow evening followed by decreasing
coverage of showers overnight into early Friday morning. Another
system will bring more rain chances to the area Saturday afternoon
and evening. With the wet weather forecast, expect relative
humidity values to remain elevated through at least Friday
afternoon.
