.SHORT TERM...valid for Tdy and Tue...

Cooler temps and improved chances for showers and thunderstorms
beginning today.

A cold front moves through the area a little after sunrise for
the western zones, into Billings around 10am, and into eastern
zones around noon. Front does look like it will come in as a
couple of different waves, with a second push of cooler air
bringing the gustier winds in the afternoon. Second push also
bring some higher humidity into the area. Models have changed a
bit, favoring some earlier convection, than previously advertised this
afternoon through this evening. Development may be somewhat
limited until moisture has a chance to deepen a bit.

Tuesday looks to be the coolest day in some time, with highs in
the 80s, as an upper low tracks across southern Canada. Appears
that we will see some monsoonal moisture streams into the area
Tuesday, increasing precipitable waters, and therefore chances for
convection. Did raise pops slightly, due to potential for
increased coverage, but still not expecting heavy precip amounts.

.LONG TERM...valid for Wed...Thu...Fri...Sat...Sun...


Generally zonal flow aloft and no prolonged periods of downslope
westerly winds in the low levels will keep temperatures near
seasonal levels and bring at least a chance for afternoon/evening
showers and thunderstorms to the area each day. Best period for
precipitation looks to be Wednesday into Thursday as low level
plains moisture from the east and influx of monsoonal moisture
from the south combine over the area. Still seeing enough
CAPE/shear in the Wednesday/Thursday time frame to support a
chance for a few strong storms those days. Next stronger system
may arrive early next week. Chambers

.AVIATION...


VFR conditions will prevail through tonight. Isolated to scattered
showers and thunderstorms are expected over western
mountains/foothills late afternoon...spreading eastward through
the evening hours with local MVFR visibility in rain and wind
gusts up to 40 kts. Some areas of smoke may restrict visibility at
times near area wildfires. Chambers
