.DISCUSSION...
Issued at 233 PM CDT Mon Jun 29 2026

Today and tonight...the to main concern is severe weather from
thunderstorms across most of the area with a secondary threat of
heat across the southern part of the Red River Valley.

Starting with severe storms, damaging wind, large hail, and tornadoes
are all possible this afternoon into the evening. The most concerning
aspect is the elevated values of low level helicity in the wrapped up
triple point along and north of a surface low pressure system. Storms
that form in this environment will have low cloud bases, and plenty of
veering winds in the low level that will support a tornadic threat this
afternoon and into the evening. A tornado watch was issued around 2pm
through 10 pm. There could be multiple rounds of storms, so please make
sure you are able to receive any warnings that are issued.

Meanwhile, a heat advisory continues this afternoon and this evening.
The morning convection did temper temperatures a bit, the humid air
mass will still support heat indices near 90 to 95 degrees. Temperatures
will cool off this evening, and storm will exit to the north as drier
air moves across the region overnight.

Tuesday through Sunday...The cooler and drier air will keep highs only in
the upper 70s to low 80s on Tuesday, with a gradual warm up to the 80s the
rest of the week. Thursday and Friday could see a few 90s across the Red
River Valley.

Meanwhile, Tuesday and Wednesday will be dry, but thunderstorm chances
return for Thursday and the rest of the week as southerly flow advects
increased moisture back across the region. Continued with the blended
guidance which shows the highest thunderstorm chances Thursday night
through Saturday.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 105 PM CDT Mon Jun 29 2026

Main concern today is for afternoon and evening thunderstorms, with
a risk of large hail, damaging wind, and tornadoes. There is thunder
in all the TAF sites, and we expect storms to develop this afternoon
and last into the evening. There is some uncertainty with
timing, but we`ve opted to prevail with a mix of VCTS & -TSRA
for our sites. Additional AMDs may be necessary to fine tune TAF
based on convective initiation.

Once the storms move through, expect west/southwest winds to develop
and bring drier air across the region with VFR conditions, which
will last into Tuesday.
