PM Update: Showers diminish, then fog, then warmth

In some locations, rain overachieved today and, in most, temperatures underachieved. Take Dulles Airport, which received 2.26” of rain - a daily record - and has only warmed to 66 degrees, about 10 degrees below the forecast. Much warmer air is coming, but with clouds and fog around into the Wednesday morning, we won’t feel it in full effect until the afternoon.

Through Tonight: There’s a small (30 percent) chance of showers through the evening. Otherwise, it’s mostly cloudy with some patchy drizzle and areas of fog which could become dense late at night. Temperatures are steady in the upper 60s to near 70.

Wednesday: Low clouds and fog may linger in the morning, but sunshine should eventually win out. By afternoon it’s partly sunny and much warmer, with highs 80-86 (highest southeast, lowest northwest). With some lingering moisture around, I can’t totally rule out a shower/storm.

Today’s rainfall: As mentioned above, Dulles Airport received an impressive 2.26” today, breaking the daily record of 1.18” from 1973. But rainfall was highly variable in the region. Reagan National only received 0.43” whereas BWI picked up 0.54”. Generally, less rain fell south and east of the city compared to north and west. In northern Montgomery (around Gaithersburg and Germantown), Frederick and western Howard county, more than 2” of rain fell in spots resulting in a number of reports of flooding.
