.SHORT TERM...
/Updated at 0347 AM CDT Wed Apr 13 2022/

Through Thursday.

Currently watching a MCS slide east toward the western portions of
the area. This MCS is linked to a meso-low moving through
northwestern MS this morning. It is currently sliding east northeast
and is currently matched up fairly well with model consensus of the
short range range models. There is a little more in overall
convection on the south-side of the MCS that models indicated, but on
a whole tracking fairly close to the blends. Look for this low to
continue to slide east-northeast, dragging the MCS a touch more
northward over the next several hours, while weakening in over
strength as well. Updated pops this morning for the track of the MCS
and meso-low. This shortwave works out of the area later this
morning and we will warm up nicely across the region. As we work
into the afternoon hours we should see the beginning of the next MCS
to our west and then that will slide through us during the evening
and overnight.

As it moves through there will be a severe threat for tornadoes,
hail and wind in addition to heavy rainfall. The good news for most
of our area is the main dynamics will be weakening over time thus
reducing the threat for severe weather as time passes. Really looks
potentially dangerous to our west in western Mississippi based on
soundings and forecast severe parameters. Again it looks like the
overall environment will be on the weakening trend but any prolonged
storms will will need to be monitored as they move from the west. As
we work through the night, the instability drops off even in the
more robust NAM solutions, so confidence in the decreased threat
continues. Most of the heavier precipitation associated with the
main line should be exiting the region by 10 AM Thursday. There are
some better instabilities with a few models Thursday morning in the
southeast, but most of this is behind the front.

.LONG TERM...
/Updated at 0347 AM CDT Wed Apr 13 2022/

Friday through Tuesday.

The frontal boundary remains to our south through most of the day on
Friday, but does slowly start lifting northward. This could lead to
some isolated showers and thunderstorms across the southernmost
counties by Friday afternoon. Rain/thunderstorm chances continue to
increase Friday night into Saturday with several rounds of precip
expected over Easter weekend and into Monday. This is due to the
stalled frontal boundary remaining draped across the area under
generally zonal flow aloft. A couple of shortwave impulses move
along the boundary over the weekend. Timing remains a little
uncertain with each wave, so overall rain chances remain capped
around 40-50%. This will likely increase in coming days as we get a
better handle on the timing for each impulse.

As we begin next week, a slightly deeper shortwave trough is
expected to slide through, developing a weak low pressure system
somewhere along the Gulf States. This will push the stalled boundary
south of our area by Monday evening into Tuesday, ending any
significant rain/storm chances. Right now, this Monday system
remains on the weaker side, which limits any northward progression
of a quality warm sector, so we really don't see much instability
across Central AL ahead of the low pressure system. Because of this,
the severe potential appears to be limited at this time.

.AVIATION...
12Z TAF Discussion.

A meso-low is spinning through northern MS this morning and and
generating some light showers across the state. Rainfall was much
more widespread earlier, but have since decreased. Look for the
rain to move out this morning and then generally only isolated
showers through the day. The big rains come after 00z tonight and
will impact most sites through the end of this cycle.

Note: AMD NOT SKED for ASN, MGM, TOI due to communication issues
and observations not available.

.FIRE WEATHER...

Rain chances will increase this morning in areas west of Central
Alabama. 20ft winds will stay up overnight from the south at 5-7
mph and become brisk on today with south winds 10-15 mph. Rain
chances will continue to increase Wednesday night as a cold front
approaches the area, with locally heavy rainfall at times
Wednesday night and Thursday morning.
