.SHORT TERM /THROUGH TONIGHT/...
Issued at 202 AM MDT Sun Jun 21 2026

After a thunderous Saturday, today`s thunderstorm, possibly
severe, threat will be mainly confined to the Nebraska
Panhandle. Hi-res guidance is picking up on this convection and
starting it around 1PM this afternoon. This activity appears to
be scattered in nature as it moves east and out of our CWA by
6PM this evening. Even so, severe parameters aren`t the best,
so the main threats will be hail and wind. The better instability
should stay off to the east, across central Nebraska. With the
influx of moisture over the last 24 hours, today will start off
with a few patches of fog across the Nebraska Panhandle and far
eastern Wyoming. This fog won`t last long as winds turn
westerly after sunrise due a to frontal passage. With minimal
mid-level support, there are no indicators of high winds across
the CWA for this short term period. However, can`t rule out
localized breezy conditions in our known wind prones across
southeast Wyoming. Temperatures will be slightly cooler today
with highs in the 70s west of I-25 and low 80s off to the east
of the corridor. While lows Sunday night will dip into the 40s,
near 50 across the Nebraska Panhandle.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 151 PM MDT Sat Jun 20 2026

Monday into Tuesday, a low pressure system drops into the
Northern Plains sending a frontal passage through our area. This
weak front will bring some cool air over the Intermountain West
keeping our temperatures mostly in the 70s for both days, but
some isolated 80s will be possible as warm dry air starts to push
in from the west. As more of the dry air begins to filter in
overnight, RH values west of I-25 will start to drop into the
teens while everything east will stay into the 30s and 40s.
This dry air will most likely follow the upper level ridge that
sets up on the West Coast and slightly pushes east. The ridge
does look to compress on Thursday and Friday, allowing for some
continued chances for rainfall as more troughs/systems push
into the Pacific Northwest from the Gulf of Alaska. This active
pattern could potential last through the weekend if the ridge
and dry airmass stays centered over the southwestern part of
the United States.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1122 PM MDT Sat Jun 20 2026

Low CIGs are plaguing KSNY, where IFR CIGs are expected throughout
the overnight hours, improving by mid-morning. Skies cleared at
KAIA and confidence isn`t the highest that CIGs will drop to or
below IFR, so kept it out of the TAF at this time. Gusty winds
return during the morning hours with gusts up to 30 knots affecting
all terminals, winds will become northerly at the very tail end of
this TAF period.
