Reprieve from cold on the way

A FEW MORE FRIGID DAYS IN THE FORECAST

- Dave Mabell LETHBRIDGE HERALD dmabell@lethbridge­herald.com

Just a few more days! If southern Albertans can hang on for the rest of the year — til Jan.1 — they’ll see an end to the holiday period’s blasts of winter.

The polar vortex of super-cold air will linger until the New Year’s weekend, according to meteorolog­ists at Environmen­t Canada. But Jan. 1 could dawn bright and balmy — just -4 C in Lethbridge that day, they’re predicting, and -2 the day after.

Later in the week, their colleagues at the Weather Network are calling for plus 2 next Thursday, a week from now.

But overnight lows will remain in plug-in territory until Dec. 31, warns the Environmen­t Canada forecast. As of Wednesday afternoon, this morning’s low was predicted at -24 C — followed by -26 tonight, -27 on Friday night and -29 Saturday night.

Wind chills were predicted to be as cold as -34 C on Wednesday night, -31 tonight.

Periods of snow are also likely until Sunday, forecasts say. Then skies will clear as the current cold snap — powered by an upper layer of frigid air that spilled over the North Pole from Siberia — begins to moderate.

Officials have lifted the extreme cold warning for Lethbridge and southweste­rn Alberta meanwhile, though an alert was still in effect Wednesday for Medicine Hat.

The new year will begin with much warmer weather, The Weather Network predicts. After a high of 2 C next Thursday, forecaster­s are expecting daytime highs in the -4 to -6 C range through the following week, with overnight lows of -7 or -8.

Forecaster­s are reluctant to look further ahead than that. But they point to long-term weather records for January as an indication of what Lethbridge and southern Alberta residents can expect.

Mid-month temperatur­es in January usually hover around zero during the day, dropping to -10 or 12 overnight, the records show.

Later in January — with just two months until it’s officially spring — the city’s longtime averages have continued to reach zero or plus 1 in the afternoon, dipping to -10 or -11 at night.
