.SHORT TERM...
(Today through Sunday)
Issued at 1245 AM CDT SAT JUN 14 2025

A rinse and repeat kind of forecast for the weekend. While not a
complete washout, showers and thunderstorm chances are very good
with pretty much greater than 70 percent each afternoon. Highs
will be in the upper 80s to near 90 before the rain activity
begins. Much like yesterday, a few of the storms will be strong,
and will need to monitor as the pulse through the heating of the
day. Heavy rainfall will accompany these storms so localized
flooding will be a threat. Much of the activity will dissipate by
Midnight.

Previous long-term discussion:
(Sunday night through Friday)
Issued at 1001 PM CDT FRI JUN 13 2025

Sunday night through Tuesday, high pressure will be over the
southern Florida/eastern Atlantic region, with another area of
high pressure over TX and the southwest. Weak troughing will be
present between the two high pressures, just north of the area.
Low and mid level winds will be from the southwest bringing
moisture and warm air advection to the state. There is a medium to
high chance for diurnal thunderstorms Monday and Tuesday
afternoons. Instabilities should be anywhere between 2000-3000
J/kg with PW values near max for this time of year. The wind
profile will be fairly weak with weak shear, so summer time,
develop-build-collapse storms will be the most popular mode of
convection these two days.

By Wednesday, the pattern shifts slightly with the trough
weakening and zonal flow prevailing to the north of the area. The
high pressure over the southwest will begin to strengthen and move
east, with the high over the Florida area maintaining influence
over the state. Low and mid level flow could shift to a more
westerly direction, with PW values decreasing from over 2 inches
to around 1.6 inches for much of the area. Models are trying to
hint at a low chance for Wednesday to be the day with the least
amount of coverage with light winds and lower instabilities, and
diurnally driven convection continuing Thursday through the
beginning of next weekend.

With southwesterly to westerly flow through the long term period
bringing moisture and warm air, heat indices will be in the upper
90s to near triple digits in many areas of the west and southwest.
Will need to keep an eye on these trends for increases in the heat
threat.
