A look ahead
Thursday continues this incredible streak of deep cold, with sunny skies and highs in the upper teens to mid-20s. Thursday night should see clear skies with super-cold low temperatures in the single digits. Some locations could reach zero or lower. Confidence: Medium-High
Friday features the coldest daytime temperatures of this week and the winter so far. Mostly sunny skies do little to take the edge off high temperatures in the teens to near 20. Partly cloudy Friday night and still very cold with single digit to low teens for lows. Confidence: Medium-High
The weekend is a tricky one as weather models flirt with the idea of a coastal storm system. This feature could stay far enough offshore to keep us dry, but there’s also a slight chance of substantial snowfall.
Regardless, expect cold highs in the 20s and lows in the teens, along with gusty winds that make it feel even colder. Confidence: Low
Next week brings a continuation of colder than normal conditions, but it does not look as severe as this week with 30s for highs and teens and 20s for lows.

The snow potential index is a daily assessment of the potential for at least 1 inch of snow in the next week, on a 0-to-10 scale.
