.DISCUSSION...
Issued at 319 PM CDT Fri Jul 5 2024

A weak disturbance moving across the area today sparked a few
light showers/sprinkles across the area. These showers have
struggled to get going, although an isolated non-severe
thunderstorm remains possible through the late afternoon hours
when surface instability should begin to wane.

A much stronger upper level disturbance can be seen in water
vapor imagery across north central Montana this afternoon. This
disturbance is forecast to rapidly track southeast over the next
18-24 hours, helping provide forcing for line of strong to
severe storms across the local area Saturday afternoon. Given
the timing of this upper level disturbance, storms could get
firing rather early in the day on Saturday, with the anticipated
line of storms developing as early as noon across our north
transitioning southeastward through the afternoon hours. Models
have come into much better agreement with timing of this
disturbance over the past 12 hours, focusing earlier in the day
with the main threats being large hail (elevated storms with
decent deep layered shear) and 60 mph wind gusts. Given the more
progressive nature of these storms, may have hung onto pops too
long into the evening hours Saturday, but there could be some
non-severe trailing activity into the overnight hours.

Yet another upper level disturbance in the longwave trough is
anticipated to cross the area on Sunday bringing another round
of thunderstorms. That said, with the better shear anticipated
further south on Sunday and lower available instability, the
strongest storms should be contained to our north central
Kansas counties Sunday afternoon.

Behind Sundays system, the upper level ridge across the
southwest is expected to amplify resulting in northwesterly flow
aloft, helping to keep temperatures on the cool side of normal
to start the week. The next weak disturbance is the expected
mid-week, but overall, this should only result in very small and
spotty chances for thunderstorms during the Tuesday evening
through Wednesday night time period.
