If you are watching this after Monday, then you may wish to check the NWS webpage or call
any of the Montana NWS offices for updates as conditions may have changed.
Beginning today, Arctic air over northeast Montana will combine with gusty east winds
to produce wind chill values well below zero on Monday night and Tuesday night. Blowing
snow will also cause areas of drifting across roadways.
The NWS office in Glasgow has highlighted these impacts in their Monday Morning weather
story. Scattered snow showers are expected to spread
from west to east Tuesday night through Thursday, affecting areas from the western and southwest
mountains across to southeastern portions of the state. Impacts will be minor, but could
include locally reduced visibility and snow covered roadways.
Early guidance indicates a possible winter storm affecting portions of the state from
west to east over the weekend. Potential impacts include accumulating snow at higher elevations
with difficult driving conditions through mountain passes. Confidence is low and this
system could generate more widespread impacts, so please watch for updates throughout the
week. The week two outlook from the Climate Prediction
Center indicates a slight chance that north-central Montana could experience warmer than normal
temperatures and above-average precipitation for all but the south-central mountains.
Overall the coming work-week presents minimal weather hazards. We note the wind chill concerns
for northeast Montana tonight and tomorrow night and scattered snow shower activity causing
locally difficult driving conditions Tuesday night through Thursday. Early guidance suggests
the possibility of a winter storm affecting portions of the state for the upcoming weekend,
particularly higher terrain, but with presently low confidence.
If you have any questions or concerns, contact any of the four Montana NWS offices. We are
available 24 hours every day.
