Forecast: Stormy End to Week

By Josh Larson

Clouds, wind & rain likely through Saturday

*Wind Advisory until midnight east of D.C.*
*Gale Warning until 6 a.m. Friday for tidal Potomac, Chesapeake Bay*
*Coastal Flood Advisory until 6 a.m. Friday for tidal Potomac, western Bay shore*

In light of the ideal early fall weather over the last week, the next few days of unsettled weather will be all the more unwelcome for many. A strong coastal area of low pressure will push towards our region -- perhaps acquiring some tropical characteristics -- and will bring thick overcast skies along with rain and wind today and tomorrow. Lingering clouds and showers will probably stay with us on Saturday, though -- fingers crossed -- Sunday's weather may be more conducive to outdoor activities.

Windy; rain developing. Low-to-mid 60s. No matter how early you wake up, you'll likely rise to overcast skies and breezy conditions. Rain should overspread the area from SE to NW during the late morning or early afternoon hours. During this time, winds from the northeast will increase to 15-25 mph with some higher gusts (especially to the east) possible to 40 mph. Rain and low clouds will hold afternoon highs only in the low-to-mid 60s, while the wind will make it feel even chillier.

Conditions tonight will be unpleasant, with overcast skies, bands of showers and occasionally heavier rain, and continued gusty winds of 15-30 mph. Temperatures will remain nearly steady in the low 60s. Rainfall totals by Friday morning will probably be in the 0.5-1" range -- with the highest amounts to the south and east. Totals should not approach those from tropical storm Hanna.

Confidence: Medium-High

Keep reading for the -- at times, rainy -- forecast through the beginning of next week. See also NatCast for the final game of the season.


Periods of rain. Near 70. Friday's conditions will resemble today's, though won't be as disruptive. For starters, rain should be more intermittent. Secondly, wind should be much less noticeable -- generally near 10 mph. It will also be a tick warmer, with afternoon highs near 70.

Do be sure to bring an umbrella with you if you leave the house Friday night since some showers may linger, with overnight lows in the mid 60s.


If you're hoping for nicer weather on Saturday, you may have to look elsewhere. Our pesky area of low pressure will continue to provide overcast skies with periodic showers throughout much of the day. It will be milder, still, with afternoon highs in the mid 70s. Occasional showers may linger into Saturday evening with overnight lows again in the mid 60s. Confidence: Medium

Hold your breath if you're expecting much in the way of sunshine on Sunday. Mostly cloudy skies with widely scattered showers will probably typify the first part of the day. The second half of the day should be dry, but it will still be mostly cloudy. But a few peeks of sunshine may help afternoon highs head to near 80. It will be partly cloudy and dry Sunday night with lows in the mid 60s. Confidence: Medium

The outlook for Monday calls for...drum roll, please...the return of sunny and dry conditions. Afternoon highs will again be within a few degrees of 80. Overnight lows should settle into the low 60s in most places. Confidence: Medium

Good sleeping Weather! NWS LWX canceled the high wind watch to the west.

It's partly cloudy here. It was actually a really nice morning - partly cloud, crisp and not breezy at all. Huh. Is Lake Ridge immune to the weather? Hehehe.

Old Sol still shining out here, but it's brisk. Looks like I'll have just enough time to get in my walk before the rain arrives. Check out radar near Norfolk!

Where is Lake Ridge? Is that a city or what?

Rats, tonight is free Coldstone. Saturday is the National Book Festival. How do things look for attending that? Will the showers be enough to make it not a good idea to attend?

I know it's been covered before, but can someone explain what makes a storm a tropical storm or depression? How is it different from a plain old nor'easter?

Lake Ridge is a census-designated place that is west of Woodbridge - south of Clifton- east of Manassas. Great place actually..

Richard: At a very basic level, a tropical storm gets its energy from warm ocean water. A typical coastal storm or noreaster gets its energy from temperatures contrasts (cold air interacting with warm air). You can also have hybrid storms that get energy from both of these factors, and one might argue that's the kind of storm affecting us now.

We are expecting the rain here as well. Clouds are beginning to move in but most outlets hold the rain off this far west until tonight. I'm hoping it holds off long enough for me to get some time in on the bike tonight! After that, it can rain all it wants - we still have about a 6" deficit down here.

Richard -

Kevin Myatt with the Roanoke Times has a pretty good discussion of tropical vs. non-tropical and how it relates to this current system. Check out the two blog posts from Sept. 24 here:

Anyone that "lives" in Woodbridge actually say that they live in Lake Ridge as it is the only nice place to live in the over developed and gang plagued region.

Here it comes ... a wall-o-water (from the sky).

Not just a "Dancewrecker", but a weekend-wrecker as well!!!

NHC is still considering whether to name this monster "Kyle"...or "Laura" if the system north of Puerto Rico goes "tropical storm force" first!

Lots of interesting cloud formations with this system...primarily stratocumulus after yesterday's advancing Ci/Cs shield. There's some lightning off the Carolinas per StrikeStar U.S. and Vaisala. We could see a thunderstorm or two tomorrow.

If the wind lets up tomorrow, the dance tomorrow night is probably "on". It may depend, though, on how much rain we get.

Not a drop of rain in Bethesda yet.

Rain, some, now.

Geez, and I thought there's be no soccer practices this afternoon due to the deluge we were forecasted to get! Not a drop so far!

Thank you Storm-petrel, you have given me hope!

Posted by: GSM in Centreville | September 25, 2008 2:31 PM | Report abuse

Grouchy -- note that our forecast allowed for the possibility of rain not beginning until early afternoon.
