Record lows, frost, and even snow: D.C. area could see it all between Friday night and Mother's Day.
'Winter is coming
in May.
An extraordinarily strong blast of cold air for the time of year will spill over the Washington region late Friday into the weekend, potentially setting records while bringing frost to some and even a small chance of wet snowflakes.
The wintry blast will put an exclamation mark on a cool, dreary weather pattern that began in mid-April, during which the overwhelming majority of days have seen below normal temperatures and rain. Measurable rain has fallen on 12 of the past 14 days, totaling over half a foot.
During the upcoming polar plunge, to follow yet another bout of rain, temperatures will sink 20 to 25 degrees below normal.
Washingtonians who have put away their heavy coats may regret that decision.
Record low temperatures and frost
The drop in temperatures will come suddenly.
After climbing into the 60s early Friday afternoon, the Arctic cold front will arrive by evening, with temperatures falling through the 50s around sunset. Overnight, they should eventually plunge into the mid-to-upper 30s. For perspective, Washingtons average last instance of low temperatures below 40 is April 13.'>>>
