(Today)
Issued at 357 AM CDT Sun Jun 15 2025
Earlier showers and convection has dissipated. Very saturated
conditions are in place in the boundary layer with dewpoints right
at or withing two degrees of the actual temperatures across much
of northern Alabama and southern middle Tennessee.
However, enough cloud cover and some pockets of wind around 5 mph
have kept the fog formation at bay. Models seem to want to reform
very low stratus between now and daybreak on Sunday.
Thus,thinking fog will be very patchy, unless CIGS drop in many
locations below 500 feet. Not expecting many showers or
thunderstorms (only 20-30%) into much of the morning hours. With
the main front basically stalled to our west, additional energy
will push east into the area ahead of this frontal boundary later
this afternoon and evening. This should set the stage for another
day of showers and thunderstorms during that timeframe. Not
expecting these storms to be severe given the lack of shear seen
in most guidance. Heavy rainfall that could produce flash
flooding, frequent lightning and gusty winds to 50 mph could occur
with the strongest storms.

.SHORT TERM...
(Tonight through Tuesday)
Issued at 953 PM CDT Sat Jun 14 2025
With zonal flow prevailing aloft, we will remain in an active
pattern early this week, with a couple shortwaves rippling
through the mean flow. Given the warm and very moist air mass
(PWATs near 2"), high chances (70-80%) for showers/storms will
continue in the forecast early this week. Locally heavy rainfall
and flash flooding will remain the primary concern with this
activity given the already very wet soils. A few strong to
potentially marginally severe storms cannot be ruled out each day,
but this activity will be pulse-like and disorganized -- with
localized damaging winds being the main threats with the strongest
storms. The dense cloud cover and high rain chances will keep
highs in the mid 80s both Monday and Tuesday.

.LONG TERM...
(Tuesday night through Saturday)
Issued at 953 PM CDT Sat Jun 14 2025
A Bermuda High will begin to nose into the Carolinas and Deep
South mid to late week, helping to promote a slightly stronger
southerly flow across the Tennessee Valley and lower Mississippi
Valley. This will help to reinforce this warm/moist air mass --
and also result in a gradual increase in temperatures each day
with plenty of heating helping to nudge highs back into the upper
80s and lower 90s Wednesday and Thursday and the low to mid 90s by
Friday and Saturday. The combination of the tropical air mass and
warmer temperatures will push heat index values into the upper
90s midweek and above 100 degrees late week. Additionally, plenty
of moisture will remain in place underneath this ridge, with
medium chances of diurnally driven convection in the forecast
each afternoon/evening.

.AVIATION...
(06Z TAFS)
Issued at 1052 PM CDT Sat Jun 14 2025
A few clusters of SHRA/TSRA will persist overnight and have
included a TEMPO between 06-09z to highlight the potential for
brief reductions to MVFR conditions due to low ceilings and lower
visibilities. Low stratus MVFR may develop late tonight into early
Sunday morning, but this will give way to VFR conditions through
much of the day from mid morning through the afternoon/evening.
Once again, convection will develop later in the afternoon and
evening and have highlighted this threat after 19-20z through
01-02z with a PROB30. AWWs and amendments may be needed during
this window.
