PM Update: A winter-like chill Wednesday with a few showers

It was perfectly springlike today (warmer than forecast, in fact) but it will feel a bit wintry tomorrow. I suppose we shouldn’t complain about tomorrow’s prospect for a cooler than normal April day when such days have been so few and far between. The jet stream takes a big dip and highs will struggle to make much headway into the 50s. A few rain showers may develop, possibly even mixing with snow in the mountains.

Through Tonight: As the sun goes down, the cooling of the airmass will become increasingly apparent. It’s partly cloudy, blustery and cold overnight, with lows from 35-40 (suburbs-city). Winds from the northwest at 10-20 mph, gusting higher - produce a bit of a wind chill factor too.

Wednesday: This will be one of the chilliest days of the last month. Skies are variably cloudy - tending sunnier in the morning but increasingly cloudy during the afternoon when a shower is possible (30% chance), especially north and west of the District. This is unlikely to be the big rain producer we need. Highs only manage the low-to-mid 50s - about 10-12 degrees below normal. Winds are from the northwest at 10-15 mph.
