..Synopsis

Sfc high pressure was over north central Montana at 08z. Sfc temps in this area where deep snowcover exists and winds are light are -20F below (Havre MT). High pressure will slide southeast today into eastern SD by 00z. Decreasing 925-850 mb moisture going thru today. Satellite shows stubborn clouds around still and upstream into eastern Sask/Manitoba. But also clearing areas. Will expect this cloud and sun mix today. Light winds tonight, turn southwest tonight. How low temps go will depend on cloud cover with potential for widespread single digits below zero readings.

Going thru next week the weather pattern will continue to show broad 500 mb trough over central Canada with several short waves moving southeast across the area, but each one has limited moisture and 24 hour probs of more than 1 inch of snow remaining 10 pct or less thru Friday. One wave passes thru Tuesday late into Tuesday night, then what could be the coldest airmass so far Wednesday into Wednesday night as high pressure this time a bit closer to our area Wed night and with this better clearing chances. Another clipper system Friday or Saturday. Probs using mean ensembles from ECMWF, GFS, GEM and NBM indicate Saturday 24 hour snowfall chances of more than 1 inch 20-30 percent but probs of 3 more than inches at that time period 10 percent or less.
