It may be a four-day work week for many, but the continuing weather—with temperatures dipping into single-digit territory—could make the next three days seem lengthy. On Tuesday night, temperatures in the Lower Hudson Valley sank to 9 degrees, prompting meteorologists to declare the cold front the worst in recent years.

Students at Nanuet High School were evacuated for about 10 minutes Tuesday morning due to a fire alarm, but didn't take to the outdoor sports fields as usual. Instead, children and teachers waited out the alarm indoors at the nearby middle school due to the gelid weather, according to Cheryl Tully, Administrative Assistant to the Superintendent.

The freezing weather dovetails with a particularly strong flu season, which has some local pharmacies in Rockland stocking up and some are running out. The Rockland County Department of Health has also been hosting clinics and offering flu vaccinations. Further south, authorities in Yonkers Tuesday closed Nepperhan Avenue mid-day for icicle removal.

A dusting of snow is expected Wednesday morning and early afternoon with a high of 20-degrees. Wednesday night, the temperature plunging down to ten, but wind chill factors may make it feel -2, according to the National Weather Service.

The warmest weather this week is expected to come Saturday afternoon, with a peak of about 25 degree—still a ways below freezing.
