Area Forecast Discussion

252 PM CDT Mon Jul 11 2022

.SHORT TERM...(This evening through Tuesday night)
Issued at 250 PM CDT Mon Jul 11 2022

Impacts in the short term will continue to be from scattered
showers with embedded thunder as upper wave departs NW MN late
this afternoon into the evening. Overnight skies clear out and
temps will fall within a couple degrees of 60. Then basically a
rinse and repeat of a forecast for tomorrow with another short
wave bringing shower chances to NW MN in the NW flow aloft. The
track of the wave is a bit further east with the western edge of
activity likely not in the valley tomorrow afternoon. Also will
see temps a touch warmer tomorrow as well with some low to mid 80s
in the valley and west and a bit less of a northwesterly breeze.

.LONG TERM...(Wednesday through Monday)
Issued at 250 PM CDT Mon Jul 11 2022

- Warmer temperatures return from Wednesday onward
- Thunderstorm chances Thursday into Friday
- Progressive and uncertain storm track this weekend
- Slight chances for thunderstorms into next week

Looking into the Wednesday through Monday period, the primary
concerns will be hotter temperatures and thunderstorm chances later
this week. Strong H5 ridging builds into the Central and Northern
Plains by mid-week, with a ridge axis extending northward into
Nunavut. Heights will be at a maximum over the Four Corners Region
and will approach the 600 dm mark by late Wednesday. Upper flow
across the forecast area is expected to be northwesterly for
Wednesday, then turning westerly by midday Thursday. This will allow
temperatures to climb into the upper 80s to middle 90s. Ensemble
guidance is increasingly agreeable regarding a shortwave riding
across the upper extent of the ridge, bringing thunderstorms back
into the area heading into Thursday afternoon and evening.

Additional thunderstorm chances are in the forecast Friday and into
the weekend; however confidence in a single solution is low at this
point.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1237 PM CDT Mon Jul 11 2022

Showers and thunderstorms will continue to move across the TVF
and BJI locations this afternoon. Thinking activity will stay east
of GFK but will need to monitor the western edge of the line of
convection sliding south in N MN this afternoon. NW winds gusting
25 to 30kts today will diminish with sunset. VFR overnight at all
TAF locations.
