.SHORT TERM...
/Updated at 714 PM CDT Tue Jun 07 2022/

Strong to severe thunderstorms have developed along a remnant
boundary northeast. These storms have produced damaging winds,
large hail and flooding rainfall. MUCAPE values are still around
2000, Bulk Shear around 25, Precip Water values have increased to
1.8 or so, good low level convergence, and plenty of instability.
These storms will continue for the next few hours with a chance
of severe and flooding before a gradual weakening trend ensues.

A short wave trough/MCV over western Mississippi is moving toward
Central Alabama and will provide additional lift mainly after 10
pm. Low level convergence increases with this feature, Bulk Shear
increases to 30-35, MUCAPE still around 1500, and instability
still sufficient. This feature will also be a potential strong to
severe thunderstorm producer and local heavy rain is possible.
Have increased pops and pulled them farther south into the
Tuscaloosa and Birmingham areas overnight.

Wednesday...the persistent boundary will keep the focus of
showers and thunderstorms across the northern counties through the
morning hours. By the afternoon...a shortwave will be the driving
factor moving the activity farther south into the eastern
counties of the area. Instabilities will be around 3000
J/kg...with high PW values and stronger mid and upper level winds.
Storms Wednesday could become strong to severe possible with
damaging winds and large hail. Due to moisture content and
instability present, localized flooding will be possible as well.

High temperatures today will be in the upper 80s and lower 90s.
Low temperatures tonight will be in the 70s with high temperatures
on Wednesday in the upper 80s and lower 90s.

24/75

.LONG TERM...
/Updated at 0342 PM CDT Tue Jun 07 2022/

A couple changes to the long term forecast today, regarding timing
of shortwaves and best chances for storms through the end of the
week. Will trend drier on Thursday night as a front sinks south of
the area, allowing for a break in the rain chances. The next
shortwave will approach Friday morning, and pull the frontal
boundary back northward. With increasing instability Friday
afternoon and forcing with the shortwave, thunderstorms are
expected to develop by the afternoon. It is possible the east will
remain stable Friday with lower dewpoints on the "back" side of
the front. Will contain the mention of severe storms on Friday to
generally along and west of I-65.

Previous long-term discussion:
/Updated at 338 AM CDT Tue Jun 07 2022/
Thursday through Monday.

The frontal boundary that has been stalled to our north and causing
several rounds of thunderstorms will finally push southward through
Central AL on Thursday. This occurs as a surface low lifts through
the Ohio Valley and into the New England States. With the frontal
boundary moving through the region, we'll likely see scattered
thunderstorms develop mainly in the afternoon with the aid of
diurnal heating. Some storms could be on the stronger side given
the instability, but severe potential is low due to the upper
level dynamic support becoming well disconnected from the surface
forcing. Basically, we have the instability and focus for
thunderstorm initiation, but we don't really have the deep layer
shear needed to support organized severe storms. Any of the storms
that develop would likely have the potential for downbursts as
most storms this time of year would have.

The frontal boundary is draped just to our south early Friday
morning, which will likely lead to a lull in any thunderstorm
activity in the near-dawn hours. With the frontal boundary to our
south, we should see generally northerly to northeasterly flow,
which will lead to fairly stable conditions. Later in the morning
hours to early Friday afternoon, the frontal boundary is expected to
quickly lift northward ahead of an approaching upper level
shortwave. Ongoing upstream convection is expected to slide
southeastward along the boundary as it lift northward/northeastward.
This MCS could make its way into Central AL Friday afternoon into
the evening hours, leading to the potential for damaging winds, so
the severe potential will continue to be mentioned in the hazardous
weather outlook. Behind the MCS, the frontal boundary is expected to
push southward through our area again, leading to showers and
thunderstorms through the night Friday into early Saturday. By
Sunday, most guidance has the front to our south, which should
mean decreasing rain/storm chances for Central AL for Sunday and
Monday, though the latest GFS has tried to pick up on yet another
MCS in the northwesterly flow on Sunday afternoon. For now, I'm
not including that in the forecast, but it will be something I
monitor for in future model trends.

.AVIATION...
06Z TAF Discussion.

Multiple rounds of showers and thunderstorms will be possible
across C AL with NW flow shortwave activity. Some MVFR cig/vsbys
will be possible this morning with the first wave activity
especially NE areas near BHM/ASN/ANB. This afternoon and evening
convection could spread further S affecting more of the TAFs with
a second round of storms.

08

&&

.FIRE WEATHER...

Several rounds of rain and thunderstorms are expected through the
end of the week, as shortwaves interact with a frontal boundary.
Minimum afternoon RH values will be above 40 percent each day. 20ft
winds will be from the southwest to west at 5-10mph through
tomorrow, and become northwesterly Thursday.
