No updates for inherited forecast this morning. Cloud cover is
causing concerns over high temp forecast...but temps are slowly
rising...and skies should continue to clear through the morning.
.SHORT TERM...valid for Tdy and Wed...
Very little if any changes to the weather pattern for the next
couple of days. The previous forecast remains in good shape so
very little modifications were made with this issuance. High
pressure ridging will continue through the short term especially
for the day Wednesday. A weak disturbance aloft will bring a
slight chance for a shower this afternoon and evening for areas
along and north of a Livingston- Billings- Forsyth line.
Otherwise, expect partly cloudy skies through Wednesday.
Temperatures will continue to run above normal with daytime highs
in the 60s today and Wednesday. Hooley
.LONG TERM...valid for Thu...Fri...Sat...Sun...Mon...
Thursday will be a quiet weather day with ridging over the region
though could see some gap flow winds especially early if cold air
forms over Yellowstone. Easily will be the warmest day of the week
with downslope pressure gradients and strong sunshine and could
see temperatures into the 70s which would still be well short of
record highs mostly in the lower 80s.
Pattern becomes more unsettled Friday into the weekend as remnants
of Tropical Storm Seymour interact with a deepening upper level
low over the northeast Pacific. Models agree a wave moves through
the area Friday and Friday night bringing a better chance of
showers. Do expect snow levels to be relatively high with this
round of moisture even though a cold front is progged to move
through central and eastern Montana because airmass behind the
front is not very cold. Front retreats northward as a warm front
Friday night which will bring the best chance of moisture for the
plains before anticyclonic flow makes another nudge into the area
For Sunday and beyond models push a series of disturbances through
the area though trajectory of the strongest energy is mostly north
of the area. This will allow for shower chances but allows
downslope to play a role. Higher elevations will start to have a
chance to accumulation some moisture but 700mb temperatures are
close to -2C on Sunday before falling more on Monday so still a
ways out before mountains snow appears to be a concern.
Temperatures will inger in the 60s over the weekend before nudging
into the 50s next week. borsum
Light VFR shower activity this morning will diminish by midday.
Winds will gust to 25kt at times at KLVM today. Otherwise light
winds through the period with VFR conditions expected at terminal
