.DISCUSSION...

KEY MESSAGES:

- Precipitation will end by late this afternoon and a brief
  chance for wintry mix is expected across the west part of the
  area tomorrow.

- A trough will bring a chance for precipitation on Thursday and
  Friday and will bring cooler temperatures for Saturday.

WEATHER PATTERN OVERVIEW:
A zonal flow pattern is currently over the area to keep
temperatures moderated with warmer air in the south and cooler air
in the north. There is a slight chance of wintry mix tomorrow as a
weak push of southerly flow aids in some precipitation along the
surface stationary front. The flow turns more southwesterly on
Wednesday night to allow multiple shortwave troughs to move
through the overall pattern. This will aid in precipitation
chances on Thursday and Friday. There does appear to be some
overrunning of warmer air with these disturbances, so wintry mix
is again possible. Then an arctic push appears to drop in to bring
temperatures down to the single digits and low teens for high
temperatures on Saturday. Then a brief upper ridge is expected to
push in early next week.

FORECAST CONFIDENCE & DEVIATIONS:
Blended NBM & NBM90 for todays wind and wind gusts. Also
increased PoPs for tomorrow.

There is high confidence on the temperature forecast through
Sunday. There is low confidence on accumulating precipitation
occurring tomorrow. There is moderate confidence in weather type
and low confidence on precipitation amounts on Thursday and
Friday. There is moderate confidence in temperatures beyond Sunday
warming to above normal.

.AVIATION...

UPDATED: 2030Z

FLIGHT CATEGORY: VFR, then isolated MVFR after 6Z.

DISCUSSION: A brief period of rain chances is slowly coming to an
end in the vicinity of KGDV. VFR conditions are expected through
6Z before a weak disturbance moving north through central Montana
brings a low probability of MVFR conditions from 6Z to 15Z. There
is moderate to high confidence of VFR conditions after 15Z.

WINDS: West northwest at 10 to 18 knots, becoming light and
variable after 05Z, becoming southeast at 5 to 13 knots after 12Z.

LLWS: West to northwest at 40 to 50 knots now through 03Z.
