Area Forecast Discussion
National Weather Service Bismarck ND
219 PM CDT Mon Jun 20 2022

.SHORT TERM...(This evening through Tuesday)
Issued at 219 PM CDT Mon Jun 20 2022

The main story for the short term is additional chances for
widespread severe weather from this afternoon into the overnight
hours.

Presently, showers and occasional thunderstorms are occurring
along and west of a nearly stationary frontal boundary that is
essentially draped from northeastern ND down through Stutsman,
Logan, and McIntosh counties. The atmosphere is very moist and
unstable this afternoon along on the warm side of the frontal
boundary. Boundary layer dewpoints sit in the upper 60s over the
James River Valley, along with MUCAPE values of over 2000 J/kg,
while 0 to 6 km Bulk Shear values are in excess of 60 kts. This is
a primed environment for very large hail that could be up to two
inches in size during the afternoon. That said, there is some
question as to whether or not convection will blow up over the
James River Valley, or if it will slide east of the forecast area
before rapid intensification begins this afternoon.

The aforementioned nearly stationary frontal boundary will
finally be kicked eastward late this afternoon and evening, thus
becoming a more progressive cold frontal boundary, as a trough
west of the forecast area lifts up through the northern Plains.
As alluded to earlier, this will push ongoing convection eastward.
The consequence is that this trough itself is already forcing
thunderstorms southwest of the forecast area. As it lifts up
through the Dakotas, lines of thunderstorms moving into
southwestern ND later this afternoon will track northeastward
through the evening and into the overnight hours. While the
environment won't be as favorable in western and central ND this
evening compared to parts of central ND this afternoon, there is
still enough instability, shear, and moisture to where severe
thunderstorms are expected.

By Tuesday, the pressure gradient will tighten as surface low
pressure moves off to the northeast. As a result, cooler
temperatures, of which are actually near average for this time of
the year, and gusty winds out of the northwest are expected for
Tuesday. Winds may approach Advisory criteria during the
afternoon. Otherwise, a few showers and thunderstorms may linger
in northern parts of the state during the day, but by then, the
severe threat will have subsided. Conditions will be mostly dry
across the forecast area Tuesday night.

.LONG TERM...(Tuesday night through Monday)
Issued at 219 PM CDT Mon Jun 20 2022

The period starts out with a lowly amplified ridge moving over the
region, while high pressure resides at the surface over eastern
South Dakota/Nebraska and gradually meanders eastward. As a
result, mostly dry conditions and a warm day on Wednesday,
followed by a hot day on Friday, are expected. By Thursday night,
models are coming into better agreement that a trough off a south
Canadian low will cross through the region. This could bring a
return of shower and thunderstorm activity, as well as a return to
cooler temperatures (highs in the 70s) for the weekend.

&&

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 105 PM CDT Mon Jun 20 2022

Showers and thunderstorms, some potentially severe with large hail
and very strong winds, are possible at all TAF sites this
afternoon and evening. However, exact timing remains uncertain at
most sites and therefore have generally gone with rain showers
and vicinity thunder. Higher confidence exists at KJMS where
thunderstorms already exist to the west and northwest and will
likely pass over by mid-afternoon. Winds will remain relatively
light until Tuesday morning when they become gusty out of the
northwest. However, erratic winds with reduced ceilings and
visibilities are expected with any showers and thunderstorms that
pass over a terminal.
