Today: Partly sunny, windy and cooler. Mid-60s. | Tonight: Partly cloudy and cold. 37-43. | Tomorrow: Variably cloudy, cool. Low 60s. | A Look Ahead | Get Express Forecast by E-mail


Cooler than average days have been tough to come by since early March, but we'll experience a pair of them this weekend. Behind last night's front, Canadian air funnels into the region, capping afternoon temperatures in the 60-65 degree range. Once the weekend ends, a slow and steady warming trend begins. There's no rain to worry about in the foreseeable future.

Today (Saturday): Look for a mix of sun and clouds today accompanied by a gusty breeze from the northwest at around 15-20 mph with some gusts near 30 mph. Temperatures won't move a lot -- starting the day in the upper 50s to around 60 and only topping out in the mid-60s as cool air streams into the region. Confidence: Medium-High

Tonight: The air will have a much different feel than the last couple of nights -- much more wintry. Under partly cloudy skies, temperatures will steadily drop through the 50s during the evening and ultimately down into the upper 30s and low 40s by dawn. A bit of a breeze will remain -- making the actual air temperature feel about 5 degrees cooler. Definitely bring a jacket if venturing out. Confidence: Medium-High

Tomorrow (Sunday): That flow from the northwest (winds around 10-15 mph) persists tomorrow -- delivering another cool day. It's going to be tough to reach 60 degrees, but I think the April sun will do enough to get us there...maybe even a degree or two higher...notwithstanding considerable cloud cover at times. Confidence: Medium-High

Tomorrow Night: High pressure starts to build into the region from the northwest, which should allow the winds to ease. The cool, dry air overhead coupled with light winds will likely make for a crisp night -- with lows ranging from the mid-to-upper 30s in the colder suburbs to the low 40s downtown. Confidence: Medium-High


High pressure is in control Monday and Tuesday giving us sunny, seasonably mild days and clear, cool nights. Highs Monday will be in the mid-60s warming to near 70 by Tuesday. Overnight lows will generally be in the 40s. Confidence: Medium-High

Seems pretty nice out there. The main factor today seems to be the wind...

Any thoughts about frost tonight for inside the beltway suburbs? Should I bring in the annuals in pots?

It's a gorgeous and sunny, but crisp fall-like day out here in the Valley. I was thinking 8 when I was outside, but as I came inside I knew it would only be a 6. And I was right!

I think it deserves an 8 or 9 - a little breezy, but perfect temps! Y'all can have your 78 degree days, that's bordering on too hot for me.

Chilly, but probably little chance of frost inside the Beltway. My heat is off until October.

I don't believe a freeze will be a factor tonight inside the Beltway. If you have any plant extra sensitive though, go ahead and play it safe.

What is the liklihood of particulate matter from Eyjafjallajokull disrupting flights and affecting the weather within the U.S.?

After Pinatubo erupted we had a mean winter hereabouts and Laki's eruption in Iceland caused a harsh winter across the northern hempishere in 1784. No, I don't remember much about that late 18th century winter, but I've heard a lot of pumpkins were frosted ;))

Winds have picked up during the afternoon... enough to get folks on board with today's '6'? I can see the argument for 7 maybe, but 8 would be tough, especially relative to all the really nice days we've had this spring.

@JerryFloyd1, the summer of 1783 was very warm in northwest Europe (and maybe in the nascent United States too). Here's NOT hoping for a repeat of that (or the cold winter).

@Murre, agree about the hot summer; absolutely don't need it. Don't need a very cold winter either, unless it brings a lot of snow, but brutally cold winters aren't necessarily all that snowy (c.f., 1976-77, when only there was only about a foot of snow, even though it felt like hell froze over here. Of course the folks in Buffalo had just under 200" inches of snow that winter as did parts of northern WV so they might dispute the snow part of it).

I'll have to give today a 9, even with the crisp, chilly winds. I like days like this. Just wait till July/August, when it's 90-100 degrees outside and dewpoints in the'll sell your soul for a day like today.

Beautiful weather today! I give it a 9!
