Hail and Damaging Wind in North Dakota, May 7, 2022

Area Forecast Discussion

.SHORT TERM...(Today and Tonight)
Issued at 245 PM CDT Sat May 7 2022

Forecast highlights in the short term period will focus on chances
for thunderstorms today into this evening along with the potential
for a few strong to severe storms.

Currently, long wave trough over the western CONUS with strong
southwest flow aloft over the Northern Plains. Surface trough has
moved over western North Dakota, evident via a wind shift from
southerly to westerly over my far western counties. Winds have
touched on advisory level a few times at a few locations gusting
to at around 45 mph, but overall it has been marginal with most
wind gusts in the 30-40 mph range. Temperatures have been slow to
warm up, thanks to an extensive BKN-OVC cirrus deck across a
majority of western and central ND. Scattered showers about with
the only thunderstorm activity as of 1930Z over my far northwest
moving into Canada.

Potential for a few strong to severe thunderstorms remains this
afternoon and evening, though has decreased some from earlier
thinking thanks to the upper level cloud deck which has prevented
us reaching our convective initiation temperature. A few holes
are evident in the cloud deck, but only for a short period as mid
level clouds from an area of showers to our south is moving north.
Still, strong forcing will spread across the region as the mid
level wave approaches and the sfc trough continues slowly east.
Thus, despite the low potential for sfc based storms, elevated
convection is still expected as this forcing and strong shear
combines with steep lapse rates which should begin after 20Z or
so. Main severe weather threat with the stronger storms will be
large hail thanks to the lapse rates and strong shear, with a
lower potential for damaging winds.

Showers and thunderstorms will exit off to the east by late
evening, making way for a quiet overnight period with lows around
40 west thanks to dry air moving in behind the sfc trough, and low
50s southeast still ahead of the sfc trough.

.LONG TERM...(Sunday through Saturday)
Issued at 245 PM CDT Sat May 7 2022

Very active pattern through the majority of the long term period.

Quasi-stationary upper level trough remains/regenerates over the
western CONUS through Friday, sending multiple embedded waves
through the region Sunday-Friday. This will result in continued
chances for showers and thunderstorms pretty much each day this
week, with the exception being Tuesday when sfc high pressure
moving over the region will give us a brief pause in the
moisture. Extensive cloud cover and lack of strong WAA will also
result in seasonal temperatures in the 60s to low 70s, with Monday
being the coolest with highs in the 50s to around 60F.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1242 PM CDT Sat May 7 2022

Mainly VFR conditions expected during the 18Z forecast period.

MVFR conditions under showers and thunderstorms will be possible,
mainly for KBIS, KMOT, and KJMS this afternoon and evening.

Winds will be gusty and clouds will increase through the day
today. Showers and thunderstorms are possible across much of the
area this afternoon into this evening. For now have conveyed this
threat with VCTS mention, although showers and thunderstorms may
prevail through tonight across the KJMS area.
