This Week’s Weather
By John McGinley
An Arctic air mass like we haven’t seen in many winters moved in to the Foothills Tuesday afternoon bringing snow and extreme cold. Temperatures plunged to near zero by midnight with hours of moderate snow. Snow totals ranged from 2-5 inches at midnight continuing into Wednesday. Temperatures on the Plains were in the single digits to well below zero as one moved into Canada. Lowest temperatures were -30 to -35F in Manitoba. The Canyon road turned slick Tuesday night with more hazards into Wednesday. Prior to the blast we were we were basking in 40 degree highs and lows in the high 20s or low 30s. Winds howled on Sunday and Monday with gusts over 60mph. With November at an end we found an average high of 41F and lows of 26F. These combined to make the month three degrees above normal. We were drier than average with only 11 inches of snow, 7 inches below normal. Total liquid was 0.72 inches. We had 10 windy days with three having gusts over 60mph
