836 FXUS65 KGGW 191507 AAA AFDGGW Area Forecast Discussion...UPDATED National Weather Service Glasgow MT 907 AM MDT Mon Apr 19 2021 .DISCUSSION... Sent an update later this morning to fine tune and update the forecast, mostly for chance of precipitation based on the latest and best model agreement blend I could find. A good part of today and tonight will be characterized by scattered and isolated chances for a mix of rain and snow showers - in other words, of the hit-and-miss variety. Some locations may accumulate a few hundredths while others will see nothing. PREVIOUS MORNING DISCUSSION: Another shortwave will drop out of Canada Monday and bring another round of rain and snow showers over our area. Does not look like precipitation amounts will be as high as the they were on Sunday, trace to a tenth of an inch likely with snowfall amounts less than an inch expected. Temperatures will continue to stay well below normal with highs only in the 30s and 40s and lows in the 20s. Tuesday will see another weak wave drop out of Canada and give us another slight chance of rain and snow showers, however precipitation if any will remain very light. Temperatures again stay below normal with highs only in the 30s and 40s. During Wednesday and Thursday a quick moving ridge will move through the area and we dry out and warm up to where we should be this time of year with highs in the mid 50s to low 60s. Thursday night our next cold front arrives and brings another shot at rain and snow showers with highs dropping back into the 40s by Friday. && .AVIATION...
