WEATHER PATTERN OVERVIEW:
Surface low pressure over the southern Prairie provinces will
remain to our north through Wednesday morning. An upper trough
dropping into the Pacific Northwest will help to redevelop the
surface low over central/eastern Montana Wednesday evening. this
will allow colder air to drop into Montana while a moisture stream
punches northeast through Montana.

Rainfall is expected to begin over the NW zones Wednesday evening
with snow beginning over the NW zones Thursday morning then the
north-central zones Thursday afternoon.

The deterministic models were wetter with this latest run and thus
slightly higher snow totals. Advisory snowfall is possible across
most of Phillips, northern Valley and Daniels counties.

System moves out Thursday night with QPF footprints over southern
Sask and SE Montana. Temps Thursday night drop into the teens
north, low 20s south, about 15 degrees below normal.

Surface high will lock in the cold over the area Friday with high
temps only reaching the 30s to low 40s, possibly only upper 20s
near spots along the Canadian border.

Saturday. Temps should rebound into the 40s east to the 50s west
(for highs). The warming trend continues into Sunday with highs
mainly in the 60s.
