.DISCUSSION...
Next 7 days (through Friday)...
Zonal flow prevails over our region today behind last nights
weather system. Look for mostly clear skies and highs topping out
in the 40s to lower 50s. Clear skies and light winds will lead to
a chilly autumn night with lows mainly in the 20s.
Late Sunday into Monday, an upper low currently resting over the
desert SW, will drift across the central Rockies. Confidence is
increasing thats its track will cross through Wyoming into the
Dakotas by Monday night. This is a favorable track for SE MT.
Thus, the chance of precipitation over southeast Montana is
trending upward with PoPs now ranging from 40-80% mainly Sunday
evening through Monday. As temperatures decrease overnight, rain
may change over to snow showers into Monday, although little to no
snow accumulation is expected. There remains less than 20% chance
of more than a trace of snow outside of the higher hills. This
does not look like a significant precip producer for the
east...with most locations totaling under 0.10 inches of liquid.
In the meantime, easterly low level flow increases over the plains
and this upslope flow may result in areas of fog and low clouds
across our western foothills and nearby plains late Sunday night
into early Monday.
A stronger upper trough is progged to aggressively push into the
northern Rockies early this week, impacting our region later Monday
night through Tuesday night. The exact track of the associated
jet streak will decide where the best upper dynamics hit, but at
this time our PoPs reflect a decent widespread precipitation event
(40-70% over the plains, 60-90% over the mountains). The chance of
at least 0.25 ins of liquid ranges from 65% in the
Absaroka/Beartooth Mtns to 20-40% over portions of the plains.
While highs on Tuesday are expected to be in the 40s to lower 50s,
we should see some snow in the high country with 2-4 inches above
7000 ft. Details may change, so stay informed if you have travel
or outdoor plans to start the week.
For the rest of the work week, while there does not appear to be
any organized weather systems affecting our region, southwest flow
aloft prevails which may result in some unsettled weather,
particularly for the mountains. Temps remain around or perhaps a
little under seasonable averages. BT
.AVIATION...
VFR conditions will prevail through tonight. On Sunday, a weather
system will bring increased easterly winds and the chance of
precipitation to the plains of south-eastern Montana (east of
KBIL) and north- eastern Wyoming. With this, MVFR ceilings may
develop as early as the afternoon (medium chance). LA
