For most of us, say goodbye to the growing season. The National Weather Service has issued a freeze warning for the entire Washington, D.C. metro region from midnight to 9 a.m. Tuesday.
TEMPERATURES...LOW TEMPERATURES RANGING FROM THE MID 20S WEST OF WASHINGTON DC AND BALTIMORE...TO THE LOWER 30S CLOSE TO THE CHESAPEAKE BAY.
. . .
A FREEZE WARNING MEANS SUB-FREEZING TEMPERATURES ARE IMMINENT OR HIGHLY LIKELY. THESE CONDITIONS WILL KILL CROPS AND OTHER SENSITIVE VEGETATION.
If Reagan National Airport dips to freezing tonight, it would be one of the earlier freezes in the last 30 years, falling just outside of the top 5. For context, consider what Justin Grieser and Ian Livingston wrote in their recent post on first freezes in the area:
Only once in the last 31 years has DCA dropped to 32 or lower in October, and in six years the first freeze was not until December. D.C.’s “official” first freeze comes quite late, not until November 18 on average.
In other words, if it freezes tonight at DCA, it would be almost two weeks ahead of schedule. Often times, DCA is a bit warmer than surrounding locations - meaning it might find a way to elude 32 degrees tonight. But most people don’t live at the airport - so bank on fairly widespread freezing temperatures.
How cold do you think it will get at DCA tonight, and the other airports? Comment below...
