Forecast: Sticky Friday; Stormy, Too?

By Camden Walker

Weather is looking good for weekend

* Severe Thunderstorm Watch Until 5 p.m. *
* Nats-Cubs Forecast | Can Wind Farms Change Weather? *


Today: Partly to mostly cloudy. Morning shower. 50% chance of p.m. showers/storms. Upper 80s to near 90. | Tonight: Showers and storms end. Upper 60s. | Tomorrow: Partly to mostly sunny. Less Humid. Mid-80s. | Sunday: Partly to mostly sunny. Mid-80s. | A Look Ahead


The core of our weekend will be great. First, though, we have to get through a warm, sticky and potentially stormy Friday. Showers and storms have a decent chance of moving through the area during the afternoon into the evening. A Severe Thunderstorm Watch is in effect until 5 p.m. The good news is that the cold front causing the storm threat should clear out all this muggy air. We'll feel much more comfortable for the weekend, before shower chances return early next week.

Today (Friday): It's a partly to mostly cloudy day with the chance of a morning shower. With humid air and highs peaking in the upper 80s to around 90, some may welcome the prospect of cooling afternoon and evening showers and thunderstorms. Best chances for storms are between 2 and 9 p.m., with an overall 50% storm chance for any given location.

Some storms could be strong with an isolated storm producing damaging winds. There's also a chance that the bulk of the storms misses us to the south and east. Confidence: Low-Medium

Probability: 50%
Coverage: Scattered-Widespread

Tonight: The chance of showers and storms continues into the evening. By around 10 p.m. or so, any showers and storms should be exiting the area off to the east as a cold front starts to bring in drier and slightly cooler air. Clouds should diminish after midnight with lows in the upper 60s. Confidence: Medium

Rumor has it the weekend forecast has improved since earlier in the week. Is it true? Keep reading...

Tomorrow (Saturday): We'll de-humidify as the day goes on. So highs in the mid-80s will feel quite nice. As will partly to possibly mostly sunny skies and a 10-15 mph breeze from the west. It should be a pretty fine July day to get out and enjoy -- but of course wear that sunscreen. Confidence: Medium-High

Tomorrow Night: Skies should be partly to mostly clear and lows very pleasant -- in the mid-60s downtown and low 60s in the suburbs -- along with light winds from the northwest. Confidence: Medium-High

Sunday: Pleasant conditions continue with partly to mostly sunny skies and highs in the mid-80s. The only negative aspect of Sunday I can think of is that winds look to be lighter than Saturday -- under 10 mph -- so it probably won't be a great day to fly a kite. Confidence: Medium-High


A fairly uneventful end to our weekend on Sunday night as conditions cloud up a bit, but rain is unlikely to threaten. Lows in the 60s. Confidence: Medium

On Monday and Tuesday, onshore flow from the east and southeast could mean quite a bit in the way of clouds, and also the chance of some showers and a few thunderstorms. Highs near 80 shouldn't feel too bad, though probably a little more humid. Confidence: Low

Hey, we could really use some rain out here! Ground is starting to crack!

I have to say that I'm super excited about this forecast. Rain today, sun tomorrow is perfect for our tubing trip. It will bump the river level up slightly so we don't scrape bottom as much and then not to hot but plenty of sun tomorrow.

Good work guys! ;-)

So i finally bit the bullet and got a washpost ID. two years later. Now I can post again.

So... Question:

Can I get a beachCAST for the DE/MD beaches for the weekend?

Clouds and rain is slowly working its way toward us in the District!

Welcome back! Looks pretty good both days, with partly sunny skies and highs in the low 80s. Slight chance of t'storm both days, but just 20%...

Bring on the rain! That radar looks lovely...

I don't know about that. I've looked at several radars and the bulk of the rain seems to be well west of the metro area. Hagerstown and Martinsburg are getting a good soaking.

I can already see the break in the action, with the storm dividing into a portion going north east into Pennsylvania and another steamrolling due east towards Richmond. So basically the people north and west of DC will get screwed again. This is so typical for this time of year when we really need rain. So frustrating.

The ol DC split. Bulk of the action gonna miss DC metro. Few light showers is it.

Posted by: ThinkSpring | July 17, 2009 1:16 PM | Report abuse

yeah... the storms that passed well north and west were never really "our storms." i.e., it was pretty sure we were gonna miss most of that action. It's what's coming up from the south that we've had our eye on, but as was suggested in the forecast above, the stormiest of that batch may veer south and east of the area.

With luck, the dangerous weather's out of here by 8 PM...another dance tonight...

Finally, we get good drying conditions, and the "much-needed-rain" gang wants to keep us moldy!!!
