Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
219 PM MDT Sun Jun 19 2022

.DISCUSSION...(This Evening Through Sunday)
Issued at 219 PM MDT Sun Jun 19 2022

Upper ridging has slide eastward, centered over Mississippi River
Valley. Upper trough is crossing the Great Basin, with
south/southwest flow over the High Plains. A series of waves will
cross the CWA late this afternoon into the evening. Forcing will
combine with weak instability and marginal shear, but a relatively
weak cap. Storms will develop and cross portions of NE WY through
much of western SD late this afternoon and through the evening.
PWATS are estimated to be 175-200% of normal, so elevated rainfall
rates are possible with the stronger storms. Severe weather is
generally not expected, with the exception of a few strong wind
gusts given the dry and well mixed boundary layer. Over far NW SD,
better instability and much better shear will allow for a strong
to severe storm or two, but mainly across eastern Montana. Storms
will move northeast of the CWA by 06z tonight. A cool front will
cross the area late tonight into Monday morning, then a
reinforcing front Monday night. The upper trough will cross
Montana tomorrow into North Dakota, with the next series of waves
cross the CWA. This will bring another round of storms late
Monday. A few storms could be strong to severe, with large hail
and damaging winds. Generally dry weather is expected through much
of the rest of the week. Temps will rise back into the 90s by the
end of the week, along with better chances for storms.

.AVIATION...(For the 18Z TAFS Through 18Z Monday)

winds are possible near any thunderstorms. MVFR and localized IFR
ceilings will move into northeast WY and far northwest SD tonight
behind a cold front.
