By Ian Livingston

Cold front arrives Saturday with big winds and cooler air

One thing bad about this weather: It is hard to describe in a new way every day... A few storms might be nice about now. We continue to be blanketed by mild temperatures and sunshine (veiled by high clouds today). Highs are now climbing into the mid-and-upper 70s, not far from average though still above. Sunshine is in no hurry to depart but the warmth is waning, to be replaced temporarily by chillier air in a swing that is not too uncommon for May.

Through Tonight: Friday evening plans go off without a weather hitch as temperatures slowly fall toward 70. Overnight, a moderate wind from the south, and increasing clouds, keep us pretty warm with some increase in humidity levels. Look for overnight lows in the mid-to-upper 60s.

Tomorrow (Saturday): A cold front pushes through most of the area during the morning with winds whipping up from the northwest behind it. There should be plenty of sunshine and only the slightest risk of a morning shower, but winds will probably gust near or past 40 mph by afternoon. Temperatures that peak in the mid-70s early should hold steady or slowly drop through the afternoon with more significant cooling into sunset.

The cooldown: Sunday's looking chilly, no? Maybe yes (comparatively) and no (historically). Of the 4,278 May days since 1872 at D.C., 22 percent (947 total) have had highs in the 60s. Highs in the 80s, like we saw to start the month, are a little more common with 1,212 occurrences, or 28 percent of all days. Highs in the low 60s on Sunday would be a top-20 event for the date but far from the record low max of 52 in 1877. Monday has a similarly cool low max of 53 set back in 1917. Nighttime readings paint the same picture, with record lows at D.C. still mainly in the low-to-mid 30s in the coming days.
