PM Update: Scattered storms into the evening

By Ian Livingston

Heavy rain and high winds possible; Sun returns Thurs

* Lightning: To crouch or not? | String of floods raise climate questions *
* Outside now? Radar, temperatures & more: Weather Wall *

Outside a few isolated heavy showers this morning into the midday, it's been relatively quiet around here as clouds hold tough and temperatures have difficulty rising out of the 70s many spots. The threat of thunderstorms is still in play this afternoon into early evening, but the chances of severe weather have probably dropped a little as a result of today's conditions. Nevertheless, a storm or two -- especially over southern areas that may have seen some sun -- could reach severe levels with high winds being the main threat.

Through Tonight: Scattered storms developing to the west enter into the area by the time the commute gets underway. While these storms won't impact everyone, they could be locally strong. Wind damage should be the main severe threat, but I'd mainly watch for heavy rain lowering visibility and causing ponding on roadways. Storms wind down heading into sunset, though an isolated shower may persist through around midnight. Skies start breaking this evening and they'll be mostly clear by morning. Lows reach the upper 60s and lower 70s.

Tomorrow (Thursday): Sunshine returns and temperatures react by rising past what we've seen the past two days. The weak cold front passing through tonight will have little real impact other than temporarily lowering humidity levels. Temperatures rise to highs in the mid-to-upper 80s. Winds sustained around 10 mph from the northwest may be occasionally gusty, especially in the afternoon.

So I noticed while driving around thru Manassas earlier today that there is a heavy haze in the air.
What is that...pollution? Water vapor? Am I actually seeing the humidity?

The answer to all of your questions is yes. You're looking at haze -- which is all of the above.

And naturally, the Wunderground IAD Hi-Def radar shows a nice intense cell headed right downtown, where I am meeting friends at 6pm. Thanks for nothing, Mother Nature. ;-)
I imagine that scene in Truman Show where it is raining only on Jim Carrey and sunny everywhere else. :)

vtavgjoe, it's pretty small and possibly dying. Also, I'd think it would go just south at this point if it holds together. Right now it does not look like there is much out there that would be more than briefly problematic. The season of underperformers seems to march on...

The precipitation may be under preforming but the heat sure isn't.....

hereandnow1, quite true. I think we may have a legit shot at the warmest June on record given the upcoming forecast.

Centreville VA Trace of rain here; it's not even wet under the trees. Sky is getting lighter, so unless another batch churns up this evening that's all for precip & here comes another heat wave.
Too bad; was hoping for a good soaker.

So much for the NWS forecast of "widespread showers and thunderstorms". From what I saw there were very isolated showers that popped up from time to time and then did nothing. What a stinker of a forecast.

Both the local NWS and SPC offices have been a little too gung ho on recent threats in my opinion. Though this afternoon might be even lamer than I would have expected... We just enver really got rid of the marine airmass till it was too late.

This is pathetic! Just .06" here. Yet another underperforming forecast that serves only to disappoint.

With the awful heat expected over the next week, our "abnormally dry" pattern will only worsen. Now 5.16" below normal at National Airport.

But we're not in a drought!

We had more rain before I left home this morning to go to Frederick than we did this afternoon.

Underperforming weather --uh, yep.

Unfortunately the traffic did not underperform. Spent over 4.5 hours total going up to Frederick and getting home. Yuck.

You guys promise this dew-point front is coming through tonight?

We are parched at the Potomac River Bridge. The storms seem to separate to the north and south just before they get to us. Waldorf and La Plata get rain. Dahlgren sometimes gets pounded. Us? Nothing. Zip. Nada.
