Get ready to swap umbrellas for coats as region cools down

WASHINGTON — Tuesday sees the region swapping out the umbrellas for the
winter jackets after cold air began spilling in Monday night.

A strong cold front moved off the coast on Monday, and arctic
high pressure entered the region in its wake. We are going to have some of the
coldest air of the season on Tuesday and Wednesday as temperatures only top
out in the 30s!

So far, though, we’re not getting hit with the kind of snow so much of the
rest of the country got.

Winds will pick up through the day Tuesday, with gusts up to 35 mph at times. This will make for a very blustery day. What’s worse, the winds won’t die down
until Tuesday night.

Our average temperature for this time of year is 57 degrees. Daytime highs for
Tuesday and Wednesday will be more than 20 degrees below average in some
areas. Our average temperature in January is in the
mid-30s. We could break some records in the D.C. area.

The record low max (meaning that the maximum temp for the day was
the lowest ever recorded) for Nov. 18 in D.C. is 30 degrees, set in 1924. The
record low max on Nov. 19 is 33 degrees, set in 1880.

While we are forecasting higher temperatures in D.C. for Tuesday
and Wednesday (Tuesday: 34 degrees and Wednesday: 36 degrees), I do believe
some of the WTOP listening area could get dangerously close to breaking some

Either way be prepared for the cold. The good news is, it will be dry for
the rest of the work week. And temperatures will gradually improve as we go
through the remainder of the week — by Thursday we are back in the 40s; by
Sunday, back into the 50s.

By the time we head into the week of Thanksgiving, temperatures start to move
up into the 50s.
