It was a raw, cold day, with maximum temperatures only managing the mid-40s. A blanket of fog moves in overnight. Once it finally burns off Saturday, unseasonably warm air bursts onto the scene through Sunday.
Through Tonight: Showers diminish early this evening, then fog builds throughout the region overnight, reducing visibilities to under one quarter mile in spots. Use extra caution traveling. Temperatures hold more or less steady in the low-to-mid 40s. Winds are light.
Saturday: Fog hangs around stubbornly -into mid-morning and, if we’re unlucky, through noon or so. Sunshine first emerges in our west and southwest suburbs and gradually burns off the fog to the east. Highs range from the mid-to-upper 50s where the fog holds on longest to the mid-60s (southwest of town). We’ll say highs right around 60 in the District but there is some uncertainty. Winds become from the south at 5 mph in the afternoon.
Saturday night and Sunday: Mostly clear skies Saturday evening become partly to mostly cloudy late at night. It’s very mild for the time of year with lows 42-48 (suburbs-city). Sunday’s mostly cloudy, but the very warm southerly flow helps us reach into the mid-to-upper 60s. If we get some sunnier intervals, 70+ can’t be ruled out.
