PM Update: Showers and storms to dwindle

By Ian Livingston

More heat, but less humidity, on Wednesday

* Capital Weather Gang's 2010 Summer outlook *
* Outside now? Radar, temps & more: Weather Wall *

Scattered showers and a few strong thunderstorms that pressed through this afternoon are now headed east of the area, and anything else that pops up today should be isolated with many spots staying dry from here on out. Otherwise, temperatures that rose into the rather warm mid-and-upper 80s have fallen back a bit (and often temporarily) where rain has fallen. Slightly drier air will begin to filter in overnight, while tomorrow should be noticeably less humid even if still quite warm.

Radar: Latest D.C. area radar loop shows movement of precipitation over past three hours. Powered by HAMweather. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

Through Tonight: We stay with a slight risk of a passing shower or storm through early evening, but the main activity is headed east of the area. Muggy evening readings in the upper 70s and lower 80s will fall to the low-or-mid 60s in the suburbs to the upper 60s downtown by morning.

Tomorrow (Wednesday): Lots of sunshine is scheduled for tomorrow, and temperatures respond by rising above normal yet again. The thermometer should be headed into the 80s around lunchtime before topping out in the upper 80s to near 90 later in the afternoon. Winds will be light from the northwest much of the day.

Speech interupted: Yesterday, President Barack Obama's Memorial Day observance speech in Elwood, Illinois was cancelled after heavy thunderstorms impacted the town. As rain pelted him and thunder roared overhead, Obama went to the podium to announce to the crowd: "We don't want to endanger anyone, particularly the children, in the audience. A little bit of rain doesn't hurt anybody, but we don't want anybody struck by lightning." His interest in warning those in attendance aside, did Obama "violate" the U.S. government guidelines for lightning safety known as the "30/30 rule"?

Centreville VA Got about an inch of rain here. Must have been windy too, as many of my plants have been blown about. It's time to really stake/trellis them securely for the summer T-storm trials & tribulations.
I don't have to water today.....yay!

Sorry for repeating this from the other thread, I meant to put it in this one:

Question for CWG re: humidity - why is it that whenever I check the humidity of D.C. v. Los Angeles (where I used to live), it's usually about the same - in fact, L.A. is sometimes even higher - when it feels so much stickier and more humid here? Is percentage humidity not an accurate indicator of how humid the air actually *feels*?

Had a line of severe thunder lightning and rain storm go through S. arlington @ about 2pm, which I posted about in an earlier post. Anyway, I just checked my rain gauge and we got .61 or so of rain in a 20-40 min period.

70 percent chance of precip and it never rained a drop out here!

javachip: A more relevant measure of comfort and discomfort is not the relative humidity, but the dewpoint, When it is under 60, most people are comfortable, 60-70, increasingly oppressive, 70-75, very sultry. Remember: the air temp. cannot go below the dewpoint.

As an example, a temp of 82F and a relative humidity of 45% gives a dewpoint of 59F (relatively comfortable) but a temp of 92F with the same 45% R.H. gives a dewpoint of 68F (quite oppressive).
