Area Forecast Discussion
National Weather Service Glasgow MT
1050 PM MDT Wed Oct 10 2018

.DISCUSSION...
Updated minimum temps for overnight as it was already off by a
couple of degrees. Otherwise, no changed needed to forecast grids
as forecast is on track with ongoing weather situation. FGC

Previous discussion:

Clouds are thinning and/or decreasing mainly over the eastern
zones this afternoon as Canadian high pressure noses south into
the area.

A deep upper trough is lifting slowly to the northeast into the
northern plains today, but energy continues to drop southeast 
into Montana through Thursday. This may trigger a snow shower
Thursday mainly over central Montana.

The NW flow will send another disturbance, this one bigger late
Friday into Saturday. Not much precip is expected but winds will
be a factor with 850 mb winds of about 40-45 kts and cold air
advection moving through. Temps will be quite cool Saturday with
highs only in the mid-upper 30s - close to record cold Max
readings.

Next disturbance moves through Monday but much further northeast,
thus some warming will occur. The upper levels will warm a bit as
an upper ridge off the Pacific NW coast nudges east. 

A slight warmup then looks to be in store mid-week with
temperatures approaching normal levels (mid to upper 50s) as the
upper ridge nudges east. TFJ
