.DISCUSSION...
Today through Wednesday...
Sunny warm and dry conditions remain in the forecast through the
Monday. A west to east moving trof will push a weak dry cold front
through the area late tonight, bringing cooler but still well
above normal temperatures and breezy northwest winds to the area
Friday (upper 70s). Winds settle down and temperatures increase
for the weekend with highs getting into the mid to upper 80s over
eastern areas Sunday which should be the warmest day of the
forecast period.
Monday continues to be warm but a few more clouds will hold
temperatures a few degrees cooler over western zones as a Pacific
trof begins to impact areas along the divide and west by late in
the day. Unfortunately for those looking for precipitation, the
Pacific trof gets pushed back to the west a bit on Tuesday and
opens up on Wednesday allowing energy to flow eastward across
southern Canada and northern Montana.
This pattern is not conducive to significant precipitation over
our portion of the northern Rockies, though 20 to 30 percent
chances will exist over the western high terrain Tuesday and
Wednesday, and we may leak a light shower or two into the plains
Tuesday night (20% chance). With the ridge flattening out
temperatures will taper off closer to seasonal levels (currently
in the lower 70s) by Wednesday (still in the 80s Tuesday), and
maybe some highs in the upper 60s by next Thursday. Chambers
.AVIATION...
VFR conditions will prevail through the forecast period. Late
tonight into Friday, a dry cold frontal passage will bring breezy
northwest winds back across the region. With this, gusts will
generally be in the 15-30 kt range, strongest over the foothills
west of KBIL and over eastern Montana by Friday afternoon. BT
