Chilly start to April

After a springlike first day of April that saw temperatures climb to 16C in Winnipeg, the weather turned decidedly winterlike today across southern MB as a sharp cold front sliced across the region this morning, ushering in a strong push of Arctic air today. The front was accompanied by periods of snow, including a band that tracked across the city over the lunch hour producing near whiteout conditions in heavy snow, as well as gusty north winds and temperatures near-5C. The band gave a quick coating of about 2-3 cm of snow that whitened the bare landscape. Skies cleared by late afternoon, but that will allow temperatures to drop to well below normal values tonight as an Arctic ridge of high pressure builds southward. Overnight lows of -14C are forecast for Winnipeg, some 10C below normal for early April. (it's been worse though.. record low for April 3rd is a frigid -27.8C in 1932)  Unfortunately, it looks like we'll be locked in a cold pattern into early next week before we start seeing some moderation towards normal values later in the week. That will mean daytime highs struggling to get above freezing or the low single digits over the next few days, with lows in the -10C range. Luckily, no major snowfall is expected during this cold snap, with only some minor dustings expected from time to time as weak systems pass through. Look at the bright side.. this time last year, we still had 40+ cm of snow on the ground, and we wouldn't see bare ground until April 20th!
