An upper level ridge continues to build over the Northern Plains
this afternoon leading to near to above normal temperature
across the region. There is a little bit of near surface smoke
in the southwest likely to clear out tomorrow. Highs today will
sit in the 80s across the west and central with some upper 70s
in the James River Valley. Overnight lows are forecast to sit in
the 50s. Hi-Res models do have some patch fog develop across
the south and eastern half of the state early tomorrow morning.
Tomorrow, temperatures are forecast to warm into the 80s.
The upper level ridge will pass overhead during the middle of
the week bringing in a low level thermal ridge Thursday across
eastern Montana into western North Dakota this could lead to
temperatures in the lower 90s out west. While, the remainder of
the state is forecast to sit in the 70s to 80s. Lee troughing
east of the Northern Rockies and surface high pressure over the
Great Lake will lead to a north south orientated pressure
gradient. This will lead to breezy winds out west Wednesday and
much of the state Thursday. A shortwave is forecast to move into
the region late Wednesday brining in a shot for showers and
thunderstorms early Thursday morning out west and the rest of
the state during the day. Instability Thursday is forecast to be
around 2000 J/kg with around 20 to 30 kts of 0-6 km shear. CSU
machine learning program is also highlighting this day for a
low chances of severe weather. The Storm Prediction Center does
have much of western and central North Dakota in a marginal
risk for Thursday.
Daily low to medium chances for showers and thunderstorms will
continue through the end of the week. Thunderstorm and shower
activity looks to pick up Friday into the weekend as a broad
trough pushes through the plains. The NBM continues to show a
decent signal of precipitation accumulations this weekend. The
NBM has medium chances for half an inch of rain across the
state with the higher chances out west.
