PM Update: Muggy and Mild With a Shower or Two

By Ian Livingston

More clouds Thursday, some p.m. storms possible

* NatCast | Cool Summer Here, Not Everywhere | Low Dew Point? *

Isolated showers, which have created a few spots of briefly moderate to heavy rain this afternoon, could continue through evening. But many spots will stay dry. A south wind has helped turn up the humidity as dew points reach the mid-and-upper 60s across the area. Highs ranging from the mid-80s to near 90 will only slowly fall back this evening.

Through Tonight: Any showers or thunderstorms should be isolated through evening before a partly to mostly cloudy overnight with just an outside risk a passing shower. Temperatures near 80 around sunset will fall to lows ranging from the upper 60s to low 70s.

Tomorrow (Thursday): Along with high humidity and a lot of clouds, tomorrow presents this week's best chance of rain. Scattered showers and storms could break out by midday and may last into the evening. Still, coverage may not be widespread enough to get everyone wet. Highs should reach the low-or-mid 80s.

They include some typical hot spots, but
Leesburg, Fredericksburg, Easton, and Manassas are all 90°+.

When changing the content of a post after it appears, it's traditional to note the fact for the benefit of readers.
Original language: "Highs that made it to the mid-and-upper 80s . . ."

Trolling again?

DCA hit 90 as well. 5th of summer, 6th of year. Leesburg and some of those others are notoriously too warm so I'm not sure they are that valid to point to.

Strangely the thunderstorms seem to be developing north of the metro area and then moving away from the area.

How's it look at for Rehoboth this weekend?

Still rather dry around here despite all the rain-threat hype of the past few days...this could change over the next 24-48 hours.
