Excluding south Fla., when eastern U.S. lunchtime temperatures are ranging from below zero to near freezing — even 50s in south Fla. is cold! — you know it’s a rough day to be outdoors. It’s steadily warmer than it was this morning, but not by much.
Where D.C. area records stand
All D.C. area stations tested or bested their previous record lows for the date. At Reagan National, the low of 6 degrees closed in on the 130 year old mark of 5 degrees.
Further north, BWI came in with a low of 3 degrees, colder than the previous record of 8 degrees in 1988.
It appears the Dulles record of 8 degrees set the same year as BWI will also fall, but equipment malfunctions there are being assessed before making a final determination. (12:45 p.m. update: Dulles did indeed break a record low, with a temperature of 1 degree this morning).
The low of 6 degrees in D.C., while not a record for the date, is the coldest the city has been since Feb. 5, 1996. Today now also falls among the previous top 20 coldest Jan. mornings in the city since 1946.
To pick up record low maximums today, the targets are 18 degrees or lower at D.C., 21 degrees or lower at Dulles, and 22 degrees or lower at BWI.
Coldest D.C. days since 1994
Since then, it’s been slim pickins on the cold front.
Assuming the D.C. low this morning of 6 degrees holds, any high temperature at or below 26 degrees (guaranteed) will put today on the list. A high of 16 degrees or lower (unlikely) would make this the coldest day since the almost untouchable Jan. 19, 1994.
When it comes to wind chills, still running near and below zero at noon, D.C’s peak of -11 degrees earlier this morning is more or less in line with other big cold days. On Jan. 19, 1994, Washington reached -24 degrees for a wind chill.
Just part of a big frigid air mass
Some of the heart of the cold last night was just to the northwest of the D.C. region, with Pittsburgh coming in at an incredible -9 degrees, and among a number of big records set in that area:
We’re likely to add a lot of cold records for low maximums today across the eastern U.S. as well. Large chunks of the broader region are not expected to rise above freezing, and in most cases much lower.
Looking for milder temperatures?
Even places in the United States that are typically fairly warm in winter have been impacted by this cold shot.
NWS Corpus Christi posted an awesome picture of the Arctic front passing between Freer and Laredo, Tx. yesterday. That’s down near the Mexico border.
So, with Texas out of the game, perhaps head to southern Alaska.
The low at Anchorage this morning was 19 degrees. Balmy compared to the single digits and colder around here. Their high is expected to reach the 30s today. T-shirt weather.
Or perhaps just wait. As strong as this shot from the Arctic is, it eases significantly tomorrow and we head back toward normal thereafter.
A (thankfully) quick but powerful hit.
