.DISCUSSION...
(Today through Monday)
Issued at 300 AM CDT Tue Jul 8 2025

Another muggy overnight period is on display at this hour with
current temperatures in the 70s under mostly clear skies and
predominately calm winds at the surface. A present low-level
inversion will likely result in the spread of fog across much of
the area this morning. Fog should lift shortly after sunrise as a
slight uptick in winds occurs. Yesterday evening`s convection has
subsided, though shower and thunderstorm chances (20-40%) will
return as we edge closer to sunrise when a subtle shortwave
dampens the present weak upper-level ridging.

Today will be a rinse and repeat of yesterday as an upper-level
trough remains over the Upper Mississippi giving lift to summertime
afternoon convection. PWATs continue to surge upwards of 2.2
inches, nearing the top of climatology for this time of the year,
giving ample moisture for precipitation development. This
afternoon a conditional chance for severe weather will exist as
temperatures soar into the upper 80s to low 90s, aiding daytime
heating, and heights begin to fall. Forecast soundings indicate
around 1500 J/kg of SBCAPE and effective shear of around 20 kts
this afternoon. Though, some limiting factors will exist; forecast
mid- level lapse rates are only around 5.2 C/km and a barely
adequate wind shear profile could result in storms being very low-
topped. Though, given this instability profile, thunderstorms,
mainly along and north of I-40, may have the potential to produce
damaging winds through around sunset.

Moving into Wednesday, shower and thunderstorm chances will remain
much the same. The present 595dam ridge, currently centered over
the four corners region, will broaden slightly east changing the
orient of the aforementioned trough to more positively tilted.
Thus, dampening severe chances for Wednesday. PWATs will remain
upwards of 2.1 inches, nearing the 95th percentile for this time
of the year, resulting in ample moisture for showers and
thunderstorms Wednesday and Thursday (50- 70%). Come Friday
morning, the main trough will begin to de- amplify east while
another trough axis pushes into the Great Lakes region, resulting
in continued shower and thunderstorm chances for Friday. By
Saturday, the upper-level pattern becomes more zonal with
embedded, ejecting shortwaves giving lift to showers and
thunderstorms much the same through Sunday. PWATs will remain
upwards of 2.0 inches, nearing the 90th percentile for this time
of the year.

Looking into early next workweek, an upper-level ridge will
broaden from the Gulf, bringing hot and humid conditions across
the Mid-South. Shower and thunderstorm chances will also dampen
in the afternoons, comparative to this week, as this ridge
builds. As far as the heat is concerned, continuous rainfall will
keep heat indices largely less than 105F, though heat headlines
will be re-evaluated on a day to day basis.

(12Z TAFS)
Issued at 601 AM CDT Tue Jul 8 2025

VFR conditions currently across the area. Scattered SHRA/TSRA will
move through the area by midday, with uncertainty remaining on
impacts to TAF sites. Have opted to cover with VCTS/PROB30s.
Coverage will wane into the overnight hours. Light, southwesterly
winds will continue outside of any thunderstorms that could
temporarily create wind speed/direction changes.

.FIRE WEATHER...
Issued at 300 AM CDT Tue Jul 8 2025

Hot and humid conditions will continue for the foreseeable future. Fire
weather concerns will remain at a minimum for the foreseeable
future as minimum relative humidity values remain greater than
50%. Wetting rain will be present each day, greatest coverage in
the afternoon, through the workweek.
