.UPDATE...
Short wave energy ignited some convection over north/central
Wyoming this evening. This activity is moving into portions of
southeast Montana at this time. The environment is richer in
moisture in SE Montana with precip water values over an inch.
Shear values are high (50kts) and theta-e ridge spreading into
Powder River County. Lift is not that strong though, so we only
expect storms with some marble hail, strong wind gusts and heavy
rain. Any hail >= to an inch should be spotty at best we think.
Wind gusts to 50 mph plus certainly possible.
Have updated POPs and sky for trends and trajectories of current
activity. BT
&&
.SHORT TERM...valid for Sat and Sun...
Mostly sunny skies will prevail for the remainder of this
afternoon with clear to partly cloudy skies expected this evening
and overnight. A weak disturbance and surface trough may trigger a
few thunderstorms over the mountains and adjacent plains through
this evening so we will continue a slight pop chance across the
area. Chances increase later this evening and especially over the
Big Horn Mountains, as well as Big Horn County and this is where
the short term HiRes models are showing some development. Models
shift these storms northeast late this evening and overnight so a
thunderstorm or two could be ongoing near the Dakota borders after
midnight.
For Saturday...An upper low over the Pacific northwest coast
moves inland into northern Idaho. Several disturbances will eject
out ahead of this low and move across north central Montana. At
the same time, a surface low will develop across southwest Montana
during the afternoon and move northeast through the evening hours.
Models are showing the best locations for severe thunderstorms
during the afternoon and evening will be northwest and north of
our forecast area across the northern half of the state. As this
low moves northeast it will swing a strong cold front across our
western areas late in the afternoon or early evening and the
remaining portions of our forecast area Saturday night. Drier air
aloft will get mixed down to the surface as southwest winds
increase during the day resulting in good compressional warming
ahead of the front. As a result, high tempeatures were increased a
few degrees with most areas seeing lower to middle 90s.
A strong cold front will sweep across the forecast area Saturday
evening. Given the dry atmosphere expected, we are not expecting
any precip with the front. The gusty southwest winds will shift to
the northwest with the frontal passage with gusts around 40 mph
possible. We will keep a slight thunderstorm chance in the
afternoon and evening across or far western areas from Park County
to Golden Valley County given better dynamics and moisture will be
across north central Montana.
Sunday will see partly to mostly sunny skies behind Saturday
nights front with a breezy west to northwest wind. Afternoon
temperatures will be much cooler with readings in the 70s to
around 80 degrees. Hooley
.LONG TERM...valid for Mon...Tue...Wed...Thu...Fri...
Work week begins with zonal flow over the forecast area and dry
conditions present across the region. Ridging begins to move in
from the west on Monday afternoon which will cue the start to a
hot week. Temperatures will be in the low 80s on Monday warming up
to the middle 90s by Wednesday as the ridge axis amplifies and
moves over the region. Can't rule some scattered showers and
isolated thunderstorms on Wednesday as the ridge axis begins to
pivot east and some monsoonal moisture tries to work around the
western edge. Temperatures cool somewhat on Thursday and Friday as
more moisture works its way under the ridge, though conditions
will still be warm in the upper 80s to low 90s with a chance for
isolated showers and thunderstorms each afternoon. Dobbs
&&
.AVIATION...
Showers and thunderstorms will impact areas generally east of KBIL
this evening and into the overnight as convection gradually
shifts north and east over the next several hours. VFR conditions
can be expected from KBIL and areas west. VCTS will remain
possible at KSHR through 04Z with VCTS possible for KMLS from 04
to 07Z. MVFR to IFR conditions and some mountain obscurations are
expected with the heaviest convection. Gusty easterly winds will
gradually diminish through the evening for western areas while
winds remain stronger across the east. STP
