.SHORT TERM /THROUGH TUESDAY/...
Issued at 240 PM MDT Sun Sep 13 2026
Scattered thunderstorms are in store this afternoon through the
overnight hours as another shortwave passes through our neck of the
woods. Some strong to possibly severe thunderstorms could develop in
the late afternoon as a surface low moves northeast through our
forecast area. CAPE values look to be between 500 to 1,000 joules
with couple potential pockets of 2,000 joules as depicted by the RAP
between 3 to 7pm. The synoptic forcing of the surface low should
sustain the showers and thunderstorms through the evening. However,
in the morning we have a substantial cap to erode away in the
morning and afternoon before any strong to severe thunderstorms
could develop. It will be a little tough too since the forecasted
convective temperature is in the mid 80`s and the forecasted high
temperature are either at or below the convective temperatures. Most
of the area is still capped with the exception of Niobrara county
according to the latest RAP mesoanalysis. Most of the hi-res models
continue to show initiation around 20/21z with true scattered
thunderstorm coverage by 00z. Synoptic winds will start to pick up
this evening as the Upper level low moves into eastern Montana and
Western North Dakota. A high wind watch and a Red flag Warning go
into effect Monday afternoon as the pressure gradient tightens and
the upper level low drags drier air across Southeast Wyoming. RH
values are expected to drop into the teens as the 700mb flow starts
to reach 50-55 knots by mid morning. Most likely winds will be
westerly 20 knots gusting 45 knots but 53 knots or 60 mph wind gusts
will be possible in our wind prone areas however, not quite sure how
much of that jet will mix down hence why it was kept as a high wind
watch. In-house random forest model guidance has kept its 30 to 40%
chance for elevated to high winds at Arlington, Rawlins, Bordeaux,
Coleman, and northern Carbon County. With these increased westerly
downsloping winds on Monday, high temperatures were raised higher
that what was being depicted by the global ensembles and the NBM.
Elevated downsloping winds are going to warm us up rather quickly
and may negate the effects of the colder airmass being pulled into
the Intermountain West behind the cold front.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Issued at 240 PM MDT Sun Sep 13 2026
Tuesday and into the weekend, the upper level low
keeps migrating east into the Great Lakes and Hudson Bay region. The
counter clockwise circulation will begin filtering cold air from the
Arctic into the region undergoing some warming/modification as it
pushes south over us. 700mb temperatures will drop between 8 and 12C
translating daily surface temperatures into the cooler 60`s and
70`s and overnight temperatures into the 40`s and 50`s. Daily
rainfall chances start to occur Wednesday as a train of Low
pressure system system are expected to travel through the
Pacific Northwest over the next 7 days. This precession of low
pressure systems will push the ridge eastward into the central
and southern plains leaving the intermountain west susceptible
to multiple accompanied shortwaves but ahead and following each
progged low pressure system.
&&
.AVIATION /00Z TAFS THROUGH 00Z TUESDAY/...
Issued at 545 PM MDT Sun Sep 13 2026
A Pacific cold front will gradually move across southeast Wyoming
and western Nebraska late tonight through Monday morning. Expect
showers and widely scattered thunderstorms to continue this evening
with another band of showers expected along the leading edge of the
front early Monday morning. Low clouds likely and some fog possible
across the eastern plains of western Nebraska.
HAZARDS/WEATHER TRENDS: Kept PROB30 groups for lower confidence
terminals for thunderstorm activity, and VCTS or TEMPO for higher
confidence through late this evening. KSNY and KAIA will be tricky
and are lower confidence with some models showing thunderstorm
activity later tonight, while other guidance shows low CIGS and
patchy fog. Expect IFR to LIFR CIGS into most western Nebraska
terminals by 09z with HREF and SREF probs above 80%. Kept it out of
KCDR due to gusty downslope southerly winds off the Pine Ridge. Cold
front will move across the whole area by late Monday afternoon with
winds shifting into the north.
