The region remains locked in the grips of sub-freezing temperatures today and tomorrow -- a prelude to what could possibly be yet another "significant" snow storm next week.

The National Weather Service has issued a "Hazardous Weather Outlook" warning that more snow could fall across the region Tuesday and Wednesday. The weather service, however, also cautions that various factors could change this forecast at this early day.

Today, meanwhile, will be sunny, but the daytime high temperature is expected to be only about 21 degrees. The northwest wind between 7 and 11 mph will create wind-chill values of about zero.

Tonight will be partly cloudy, with a low around 11. Wind chill values will feel as though it is minus-3.

It will be sunny again tomorrow, with a high of about 24 degrees, the NWS says. The wind chill will be minus-3 degrees because of the northwest wind between 10 and 17 mph. The nighttime low will be around 5 degrees, with a bone-chilling wind chill of minus-9.

Monday will again be sunny, but the high will be only 15 degrees.

And Tuesday, there is a chance snow could start falling in the late morning and continue overnight into Wednesday, as temperatures may rise to 36 degrees.
