Arctic air has taken over the Northern Tier of the United States! High temperatures this week will be effected by this blast of chill starting off today. Highs will only be in the lower 20s with lows bottoming out just a few degrees above zero. Reminder: Throughout your day today, be sure to bundle up! High temperatures paired with breezy winds out of the west will feel much colder... Real Feel Highs today remain in the single digits for much of the Twin Tiers and Finger Lakes Regions.
