Area Forecast Discussion
National Weather Service Glasgow MT
1025 PM MDT Tue Oct 9 2018

.DISCUSSION...
Tranquil weather conditions prevailed across Northeast Montana
tonight. No changes in this quiet weather pattern is expected
through Saturday as indicated in the previous discussion. 

Low temperatures will drop in the mid to upper 20s near the
Canadian border and in southern part of the forecast area.
Elsewhere, lows in the low 30s are expected. FGC

Previous discussion:
A broad upper trough is in place over Montana and the Northern 
Plains and will remain that way until a disturbance drops in from 
the northwest Thursday Night. This disturbance will nudge the 
trough to the east and put the area in a Northwest flow regime.

Basically beyond this point, we'll remain cool with disturbances
bringing a bump up in temps ahead of them then a drop. 

The next disturbance to do that will be on Saturday. The cold 
front will drop in Friday evening with windy conditions Saturday. 
Models are showing best qpf over Sask and weaken/dry with 
downslope Saturday. It won't be a great day as temps will be well 
below normal and winds will add to the chill.

A strong upper ridge off the Pacific Northwest coast will build
inland but another clipper will move in sometime early next week
to bring another shot of wind, cool air and the chance of mostly
rain showers.

It is expected that the ridge will win out later next week with
temperatures close or above normal as the disturbances stay to our
northeast. TFJ
