CommuteCast: Numerous Showers & Storms

By Ian Livingston

Warm on Friday, more storminess late?

7:00 PM: The severe thunderstorm watch has been cancelled for D.C. and locations to the west as storminess has now moved off to the east of the region. Although counties just east of D.C. remain under a watch, no additional severe weather is expected. A few isolated showers are still possible, but most locations will simply see mostly cloudy conditions through the remainder of the evening and into the night.

Tonight: Scattered showers and thunderstorms will continue into the evening before tapering off and moving east around sunset. Clouds will slowly break the rest of the night, leading to partly cloudy skies by sunrise. Lows should drop to the mid 60s in the suburbs and right around 70 in the city. Some isolated areas of fog, especially where it rains today or this evening, are possible.

Tomorrow: Friday should be somewhat of a repeat of today. Morning sunshine will give way to increased cloudiness throughout the day, and a risk of thunderstorms -- some of which could be strong -- enters the picture by afternoon. Temperatures may be a degree or two cooler, as highs generally reach the mid 80s across the region.

Keep reading for this afternoon's update, and see Josh's full forecast through the beginning of next week, as well as NatCast for tonight's game.

Afternoon Update: Expect fairly numerous showers and thunderstorms across the region this afternoon and into the evening. In addition to heavy rain and dangerous lightning, a few storms may be capable of producing hail and isolated damaging wind gusts. Temperatures reached highs in the mid-to-upper 80s, but have dropped into the 70s in areas where storms have bubbled up.

Saw lightning to the west of Rosslyn! Come and get us!! (I'm addressing the rain, not the electricity.)

I'm in the southern end of crystal city (just north of 27th street) . . cloudy but no rain yet. Wind is picking up a little . . .

From Chantilly: A big one blew up on top of here around 2pm. High winds, half-penny size hail, heavy rains causing temporary localized flooding, and infrequent but strong ground strikes. It was storming here before the radar even updated to show it. Pretty small cell, now drifting away over Montgomery. Was fun to watch.

A cell just brushed by Ballston, but I saw no wind, rain or lightning - just dark clouds to our north and west.

Annandale. HUGE cracking thunder. No wind. Sheets of Rain. Thunder moving east.

wow, things change fast - also doesn't help that I'm not near a window. It's pouring here and I hear thunder.

Intense thunder and lightning coupled with torrential rain in Crystal City.

definitely one of the louder and stronger t-storms as viewed here from SW DC.

Front just passed through here in Sykesville. Began ~3:30pm. Ended as of this post. Event began as rain mixed with BB size hail. As storm intensity increased so did volume of rain and size of hailstones. Hail went from bb size to popcorn size. As of 4pm sun is shining.

Some pea-sized hail on King Street in Old Town Alexandria, half a dozen lightning strikes, too. And there go the sirens.

Scary moments on the Woodrow Wilson Bridge about 15minutes ago. Traffic was at a standstill as torrential hail came down (pea sized)... bolts of lightening everywhere and winds that I'm sure were 50mph +

That was a very fierce storm that just left Jefferson County. Had everything in it, double. There was a zap in my house electrical box. I haven't opened it up yet to find out whether my lightning arrester gave its life for this storm. Could have happened.

Tinkerbelle, how poetic. How much chocolate do you have left?

Here in Silver Spring it's sunny, but according to Channel 4/Bob Ryan it looks like we may see a severe thunderstorm in the next half hour or so.

Murre, I had to go it alone, my chocolate supply exhausted by last week's storms. I looked for those big bars of loverly Lindt (orange flavored the best, mint second) at the store the other day, but no luck. I hope any storm that hits Silver Spring isn't as bad as what we just had.

Major thunderstorm over the Rockville area right now.

Posted by: kablammo | August 14, 2008 5:22 PM | Report abuse

Tinkerbelle, we still have a little chocolate left. I'll eat a piece for you even if the brunt of the storm avoids us.

At 5:30, radar shows a very well-defined outflow boundary moving south from the storms in Montgomery County. Could get interesting when that interacts with the NW moving gust front near La Plata. Maybe we'll see some redevelopment in southern FFX and western PG counties around 6:15 or so?

Certainly can't complain about the lower-than-average temperatures lately, but the number of upper-air disturbances and troughs kicking off thnderstorms this whole summer has just been insane. I have never seen anything like it.....and I have lived in this area for 45 years. What has happened this year is that we have not completely gotten out of the late spring/early summer (May-June) pattern that typically gives us severe storms. In a normal summer, the tropical Bermuda High takes over in late June and the westerlies/jet stream shift north until September....and we have just mild air-mass thunderstorms. For some reason that has not happened this year.....and refuses to happen. As of mid-August, we are STILL stuck in a late May/early June pattern. We will KEEP getting severe thunderstorms several times a week until this pattern DOES change.

Let it be known that I recorded .59 inches in NW Montgomery in the second storm of the day. Got nothing during the first storm which developed just south and east of us. First measurable rainfall in 24 days.

Looks like it could be nasty tomorrow evening when I go to my dance.

Currently 79F,29.90 rising. Cloudy, thunderstorm earlier this afternoon.

God forbid. Is this an outside dance?
