       A corridor of storms has set up along the northern branch of the Beltway from near Potomac through Silver Spring to the intersection with Interstate 95. They then continue to the east to near Odenton in northern Anne Arundel County. These are not severe storms but they’re unleashing lightning and very heavy rain. Radar indicates storm totals already exceeding an inch north of Silver Spring.

       As the storms are tracking over the same areas and only progressing eastward slowly, we could see some pockets of flash flooding develop. The intensity of the storms/downpours should gradually toward sunset, but a good amount of rain could fall in the mean time.

       In a short-term forecast, the National Weather Service said the storms could also produce 30 to 40 mph winds and small hail.

       Original article from 4:50 p.m.

       Temperatures rose to and past 90 for the second day in a row across the region. It was the 33rd such day in Washington, meaning we’re now only seven days of 90s from reaching the annual average. Unlike over the weekend, humidity is way up today, making it feel even hotter than it is. There’s no break in the immediate future. In fact, it probably turns hotter tomorrow. Storms may cool us off at times, though.
