PM Update: Evening thundershowers push out heat; balance of weekend decent

A cold front sweeping through the region puts an end to 90-degree temperatures for a while. Showers and storms are likely tonight and will be followed by pleasant temperatures over the weekend. We’re not totally in the clear though as nearby disturbances keep clouds around and offer a slight chance of showers both days.

Through Tonight: Showers and a few thunderstorms are likely this evening (40-60 percent chance) with the highest concentration and heaviest activity north and northwest of the District by and large. Some areas may not get much rain, but average amounts should be around 0.1-0.2” (with locally heavier totals in a few spots). Rain tends to diminish after 2 a.m., but skies remain mostly cloudy. Lows range from 65-70 (suburbs-city).

Saturday and Sunday: Both days see variable cloud cover and highs in the low 80s.

On Saturday, skies tend cloudier early, when there’s a chance of showers (30-50 percent chance), highest odds southeast of D.C. and lowest northwest. Intervals of sunshine are more likely in the afternoon.

Saturday night is partly cloudy and dry, with lows in the upper 50s in the cooler suburbs to mid-60s in the city.

On Sunday, partly to mostly sunny skies early yield to increasing clouds with a 30-50 percent chance of showers mostly in the afternoon; this time the highest odds are to the northwest and lowest to the southeast.

Just missed 95+ record: It appears that the high temperature today at Reagan National was 94, one shy of logging our 28th 95+ day - which would’ve tied the record set in 1980.
