.DISCUSSION...
Issued at 200 PM CDT Tue Jun 23 2026

Currently a stacked low pressure system sits in the Canadian
side of the Red River Valley, with an occluded front down
through far eastern North Dakota. A surface high pressure
centered in Montana has weak influence across North Dakota.
Wrap around moisture along a surface trough on the backside of
the low has popped scattered showers across the north in the
diurnal cumulus field. This will continue through the evening,
especially when that trough swings into the state. Isolated
thunderstorms are also possible with these, but no severe
weather is expected. There is a marginal (level 1 of 5) in
eastern ND for severe storms along that occluded front.

Wednesday afternoon looks similar with afternoon scattered
showers as the cyclonic flow near the low continues. Through
this week the below normal temperatures will continue in the
zonal flow. Little waves from the northern Rockies will create
on and off chances for showers through the week. This weekend a
large low pressure will dip down into the Pacific Northwest,
creating very active southwest flow in the Northern Plains
Saturday and Sunday. Moderate to strong instability is forecast
to develop as dewpoints could reach the low to mid 60s. Strong
to severe storms are possible Saturday afternoon and evening as
the trough strengthens and becomes more diffluent over the
state. In the evening a low level jet with warm and moist air
could increase in strength leading to the threat continuing
through the evening. As of now SPC has most of western and
central North Dakota in a slight risk (level 2 of 5) in their
day 5 outlook. All of this is subject to many changes as we are
still 5 days out.

Sunday looks like another day where strong to
severe storms are possible as the strong trough and warm air
advection continues. Because of this, the high temperatures
through the weekend will be much closer or above normal and
continue into next week.
