Area Forecast Discussion
National Weather Service Glasgow MT
145 PM MST Fri Feb 23 2018


A semi-permanant Arctic high will continue to have much control of
temperatures, especially for the valley locations. Temperatures
continue to fall well short of guidance while some locations on
ridge tops are close. Under conditions like this, temperatures,
sky and wind are the main forecast challenges.

But a system will begin to at least brush the CWA starting
Saturday Night in the form of wind. 850 mb winds increase with the
first system Saturday Night while the inversion weakens. This
looks to happen again late Sunday Night into Monday with a surface
low moving east across southern Sask. Drifting snow may be
confined to just SW Phillips County, not as bad as central
Montana. Will reissue the HWO for just SW Phillips County for
Sunday and Sunday Night.

After that, things are pretty quiet for much of next week until
a large closed low comes at us late Friday or Saturday. This
system will bring the area snow but enough downsloping should
limit heavy amounts. Jamba



Flight Conditions: VFR. There could be some low clouds around
again Saturday morning that would bring temporary MVFR conditions.

Winds: Decrease tonight but increase again Saturday with winds
turning to the West by the afternoon. Jamba


Wind Chill Advisory until 11 AM MST Saturday for Central and
Southern Valley...Northern Valley.
