.DISCUSSION...
Through Friday night...
Southeast to east flow remained over the area early this morning
with areas of low stratus (greatest in upslope areas) and patchy
fog. Dewpoint depressions were 4 degrees or less most places, and
patchy to areas of fog remain possible into the morning hours,
where the low clouds are able to clear off. A few isolated showers
are possible near the Dakotas border into the early morning with
a southeasterly low level jet in place.
Heights begin to rise today with westerly flow over the region.
Temperatures will climb into the 70s and 80s, a good 10 to 20
degrees warmer than the past couple of days. A shortwave is
expected to drop south and east out of southern Canada through
northeast MT this evening, and into the Dakotas by Friday morning.
Isolated to scattered showers and thunderstorms (15-30%) are
possible over northeastern areas and areas near the Dakotas border
this evening into tonight. A couple thunderstorms could be strong
to severe, with modest instability (CAPE values increasing
towards 1000 J/kg) and good deep layer shear (40-60 kts).
Southeasterly winds will transport moisture into the area, with
PWATs at an inch or more. Latest hi-res guidance shows the
potential for a couple long tracked storms crossing areas near
Miles City and Baker this evening into the early morning hours.
Main threats are strong winds and large hail. The SPC has put
northeastern areas into a marginal to slight risk for severe
weather this evening into the overnight.
Shortwave ridging builds into the area for Friday, before a wave
moving in from the southwest brings isolated to scattered showers
and thunderstorms (20-40% chance) to the mountains Friday
afternoon, spreading north and east through the evening. High
temperatures will warm a few degrees further for Friday (80s),
closer to seasonal levels. STP
Saturday through Thursday...
The long term looks to be dominated by a pattern in which we are
caught between upper level blocking in the Gulf of Alaska and high
heights over the southern US. This will keep upper level heights
normal to slightly below normal leading to seasonal conditions.
Persistent troughing to our west will bring southeast winds over
the plains and above average PWATS throughout the period. This
agrees with long term convective outlooks indicating frequent
chances for thunderstorms.
Ensembles are showing the potential for more significant troughing
to our west early to mid next week. Ensemble systems are not
indicating significant precipitation at this time though the
potential exists. Currently 75th percentile precipitation values
on the ECMWF ENS are less than 0.1 inches but 90th percentile
values are near 0.5 inches. This warrants keeping an eye on this
system for potential strengthening.
Temperatures throughout the long term will be in the 80s to low
90s F. Torgerson

.AVIATION...
Low stratus and patchy to areas of fog will persist over the area
into the morning hours with weak upslope flow in place. Expect
VFR conditions to develop across the area mid to late morning,
with reduced flight conditions holding in longest along east
facing foothills and across far southeast Montana. A disturbance
dropping out of southern Canada, through NE MT and into the
Dakotas will bring isolated to scattered shower and thunderstorm
chances to northeastern areas later this evening into tonight.
This includes KMLS and KBHK. Thunderstorms could be strong to
severe, with wind gusts to 50 kts and large hail possible, along
with local MVFR conditions. STP
