Sure it's cold. There's even some ice on area streams and ponds. But it hasn't been cold enough long enough to produce ice thick enough to bear the weight of people and pets. The National Weather Service has issued a warning urging area residents to stay off the ice. Here it is in full:

BEWARE OF THIN ICE ON LAKES...PONDS...STREAMS...AND RIVERS...

THE SUB FREEZING TEMPERATURES FROM AN ARCTIC AIRMASS THAT HAS BEEN
IN PLACE FOR THE PAST FEW DAYS HAS CAUSED DEVELOPMENT OF HAZARDOUS
THIN ICE CONDITIONS ON MANY AREA LAKES...PONDS...STREAMS...AND
RIVERS.

THESE HAZARDOUS THIN ICE CONDITIONS ARE DANGEROUS AND COULD CAUSE
PEOPLE AND PETS TO FALL THROUGH...AS UNFORTUNATELY HAPPENS EVERY
WINTER. YOUNG CHILDREN ARE ESPECIALLY VULNERABLE TO THIS HAZARD.

AVOID GOING OUT ON ICE UNLESS ONE IS CERTAIN THE ICE IS STRONG
ENOUGH TO SUPPORT THEM. THIS IS NOT LIKELY IN THE BALTIMORE-
WASHINGTON-CHARLOTTESVILLE REGION EXCEPT PERHAPS IN THE HIGHEST
ELEVATIONS OF THE POTOMAC HIGHLANDS. IT TAKES MANY DAYS AND NIGHTS
OF SUB FREEZING WEATHER TO PRODUCE A LAYER OF ICE STRONG ENOUGH TO
SUPPORT THE WEIGHT OF A PERSON.
