FORECAST IN DETAIL
The heat and humidity really get going over the next couple days with downright tropical air in on us tomorrow. All that moisture in the atmosphere translates into an isolated storm chance this evening and a better chance of showers and storms by late tomorrow and Friday. As for the holiday weekend, we're not ready to make any rock-solid guarantees, but things do look encouraging for less humid conditions with decreasing rain chances.
Today (Wednesday): The morning starts much like yesterday with temperatures rising through the 60s into the 70s. But by lunchtime we'll probably be in the upper 70s to near 80 (noon temps yesterday had only reached the low 70s). And afternoon highs aim about 10 degrees higher than yesterday, in the upper 80s to near 90. Add in partly to mostly sunny skies, moderate to high humidity, and an isolated late afternoon or evening thunderstorm and we have a very summery day. Confidence: Medium-High
Tonight: Muggy and mild are the keywords for tonight with partly cloudy skies, an isolated evening storm and overnight lows mainly in the upper 60s to low 70s. Confidence: Medium-High
Keep reading for the forecast through Memorial Day...
Tomorrow (Thursday): Get ready for a partly sunny, hot and very humid day with highs near 90 or in the low 90s. A few showers and thunderstorms could develop during the late afternoon or evening, with the chances of getting wet at any given location about 30%. Confidence: Medium
Tomorrow Night: We'll stay muggy through the evening with shower/storm chances increasing to around 50% through the overnight. A few evening storms could be strong to severe. Overnight lows are mild again -- upper 60s to low 70s. Confidence: Low-Medium
A little coastal low pressure may get into the action Friday, keeping shower and thunderstorm chances (50%) going through the day and possibly into Friday night, though high pressure trying to nose its way in from the north may tend to dry things out as we get into the evening hours. Mostly cloudy skies most likely hold highs to the 70s. Confidence: Medium
Our hopes for a pleasant Memorial Day Weekend rest on the strength of an area of high pressure trying to exert control over the region. I'm not ready to rule out lingering clouds and shower chances Saturday, but odds are pretty good the high will be strong enough for a mostly sunny Sunday and Monday. High temperatures should gradually warm -- 70s to near 80 on Saturday and Sunday with low humidity, and in the 80s to near 90 on Monday with humidity headed toward the moderate range. Confidence: Medium

ThinkSpring - I am inclined to agree with your perception! many times I have been rained-out at Wolf Trap :-)

ThinkSpring -- you need to change your handle to ThinkDry. All winter we heard you complain about snow. And now you complain about spring showers!
;)

At least we were able to mow the lawn yesterday.
I guess all that grass seed & steroid growth topsoil elements that we heaped onto it back in March would mean insanely fast growing 18 inch grass in May.
This afternoon we will celebrate the invention of air conditioning.

Speaking of the heat, MARC rail riders were delayed yesterday by heat related speed restrictions on CSX. Heat can cause expansion and broken rails. I'm not sure if the restrictions were in effect due to the heat itself or perhaps because of yesterday's diurnal range.

you know, ah___, i was going to tease ThinkSpring about that too, but we learned last winter that he LIKES thunderstorms - but maybe not on friday, i suppose. he's complex... ;-)

The biggest thunderstorm threat appears to be tomorrow evening...
Friday's threat sounds more like clouds, rain and showers with cooler temps. The day may be messier with umbrella use needed more...then on the weekend we get nice cool clear weather...unless marine flow from the east tries to mess things up.
With my dance schedule, ThinkSpring and I are more on the same wavelength...which doesn't happen too often in the winter! I'd rather have "dry" snow than that cold raw wet cruddy mess that passes for "plain old rain" here in the wintertime. Who ever closed the schools or government for a rainstorm--though the commute or just being out in it can be more nasty than being out in a snowstorm?

Thanks for your concern, folks. :)
Yes, I do like t-storms very much, but we're in a pattern where they're seemingly occurring at the same time as the one thing I look forward to every summer, Friday night outdoor concerts.
Now, onto this weekend. Just as I feared, looks like the front is gonna hang up near us on Friday night and cause Saturday to be not so nice as well. Shame, gonna ruin my Friday AND Saturday plans now.

ThinkSpring,
now i'm pretty sure it's not gonna thunderstorm on friday afternoon/evening because i put my order in early this week. so, if your concert is anywhere near falls church, you should be fine. btw, per my request, sun/mon will be clear too.

Ah, the Friday frontal passage. A rite of spring and summer.
No wonder so many of my favorite summertime outdoor Friday concerts get rained out.
