Area Forecast Discussion

.DISCUSSION...

A broad upper trough will cover most of the Western and Central US
the next 2 days keeping temperatures well below normal. Meanwhile,
surface high pressure will keep weather dry for the most part. A
shortwave trough moving through the area Thursday afternoon and
evening will nudge the trough to the east and flow aloft will turn
to the NW. An upper ridge in NW flow aloft will bring warmer
temperatures on Friday that will be near normal for mid October. 

A strong shortwave trough moves southeast through the forecast
area Friday Night with a cold front. Most of the moisture with
this system stays to the north in Saskatchewan so there will only
be a chance of rain or snow Friday Night. Main impact will be
gusty northwest winds behind the cold front Friday Night and
Saturday with much colder temperatures on Saturday. The cold
temperatures will continue on Sunday with NW flow aloft over the
area.  

A strong upper ridge off the Pacific Northwest coast will build
over the weekend which will keep the flow aloft over Montana out
of the NW for the first half of next week. A shortwave trough
within the NW flow aloft could bring a chance of rain and snow on
Monday. Then, Tuesday and Wednesday looks mainly dry at this
point. Forrester
