JOHN LARSEN WEATHER SUNDAY, JANUARY 30, 2011

ALERT: Staggering, Life-Threatening Cold this Week

Central Colorado is likely to see its coldest temperatures of the entire year late Monday into early Thursday of this week. A severe Arctic cold front presses south by mid-day Monday brining temperatures to record or near-record lows.

Highs Tuesday are unlikely to rise above ZERO, with overnight lows dropping to as low as -20 with wind chills to -35. These bitterly cold temperatures will be accompanied by at least a few inches of snow — I’m thinking 2-5″ Monday into Tuesday — but the big story will be the shocking cold.

Updates to follow…
