Area Forecast Discussion
National Weather Service Birmingham AL
402 PM CDT Tue Jun 7 2022

.SHORT TERM...
/Updated at 1237 PM CDT Tue Jun 07 2022/

A boundary has been left to linger over northern Alabama and
southern Tennessee...creating the focus needed for thunderstorms
to develop through the afternoon. The chances for convection will
be higher closer to northern Alabama...and chances will be lower
towards the southern counties where the main forcing mechanism is
missing...and there is a large cap in the midlevels preventing
development.

For the northern half of the area this afternoon...instabilities
will be between 2500 and 3000 J/kg with very low levels of shear
and PW values between the 75th and 90th percentile for this time
of year. With all of these present...would expect a few storms to
become strong with damaging winds the main threat from any storms
collapsing and producing outflow. With the high amount of moisture
in the air...any storm is capable of producing heavy
rainfall...and a few areas may see localized flooding if any
storms train over the same area.

This activity is expected to remain into the evening...weakening
slightly after sunset. Overnight...the boundary remains...but the
low and mid level winds weaken. Storms will continue through the
night across the northern counties...though coverage should
become more isolated to scattered in nature.

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 with isolated severe possible. Any
thunderstorm and stronger shower will produce heavy rainfall with
localized flooding 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.

.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 0338 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...
18Z TAF Discussion.

A boundary will keep the focus of thunderstorms across the
northern TAF sites through the afternoon and overnight tonight.
VFR conditions are expected unless convection moves over a TAF
site where visibilities could drop to MVFR or less. The activity
will continue through Wednesday morning. By the early afternoon
Wednesday...enough forcing will be present for activity across
almost all of the area...except for KTOI.

24

&&

.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.
