From the devastating surge to crippling snow, Hurricane Sandy by the numbers

By Justin Grieser

Superstorm Sandy slowly weakened over land Tuesday, but not before leaving behind a devastating trail of destruction across the Northeast and Mid-Atlantic. Initial estimates suggest the powerful storm has claimed at least 51 lives and caused up to $20 billion in damage.

D.C. area forecast: Halloween is a ‘go’ in the wake of Sandy

By Dan Stillman

A few days ago many Washingtonians wondered what would become of Halloween in the wake of Hurricane Sandy. Well, Sandy has come and gone, and despite doing plenty of damage to the area and an ongoing risk of river flooding, it could’ve been much worse. So while much of the Northeast Corridor is in the midst of a long clean-up and recovery, trick-or-treating is a go for D.C. and vicinity.

PM Update: Sandy’s showers end tonight, but raw for Halloween; river flood risk

By Jason Samenow

There’s a light at the end of the tunnel. Sandy’s center drifts north into New York state through Wednesday, weakening along the way. Although rain ends, coastal flood worries grow. Not to mention, it’s quite chilly.

D.C. area forecast: Sandy lingers today, then gradual improvement

By Matt Rogers

Sandy showed us her worst yesterday through last night and now she is left to spin out a slow death pretty close by. We are still contending with rain and occasional wind gusts along with chilly air that is wrapping around the decaying low. I wouldn’t even be surprised to see some snowflakes mix in north and west of the city, particularly in the early morning. Slow improvement carries us into Wednesday with partly sunny skies late this week into the weekend. Temperatures stay toward the cool side, featuring highs in the 50s and lows in the 40s this week with some 30s possible this weekend.

At this point it’s pretty simple. Don’t go out if you don’t need to today. If you have to get somewhere this morning, it won’t be pleasant but you probably can if you’re careful. By around mid-afternoon, it becomes life-threatening. By now you should have your flashlights ready and cell phones charged. Many of us may lose power, and may not get it back for multiple days.

Today, forecasts have converged on one scenario for Hurricane Sandy’s impact on Washington, D.C., and it’s severe.

D.C. area forecast: Weather trends worse on Sunday as Sandy approaches

Sandy is still lurking off to the south and not much has changed with the forecast for its arrival. The bottom line is you should move to complete any preparations for the storm, whether it be the risk of prolonged power outages or otherwise. Fortunately for those looking to salvage some fall revelry this weekend, today is passable at the least, and without many concerns. Conditions start to noticeably trend downward tomorrow, and it gets worse into the work week.

Tropical storm Sandy likely on the way, possible East Coast encounter next week

By Brian McNoldy

There are two areas of disturbed weather across the Atlantic basin: one in the southwest Caribbean, and one in the middle of the ocean far from land. While both disturbances are expected to intensify, the one in the Caribbean - likely to be named Sandy - could potentially affect the East Coast of the U.S. next week.

A developing area of high pressure becomes large and in charge this week, and that means we’re mostly high and dry weather-wise. Gradual warming brings us from the 60s today to a shot at 80 by midweek. So, if you’re not yet wholly ready to give yourself over to autumn’s chill, then you’re sure to enjoy this forecast!

D.C. area forecast: Slight weekend cooldown to near normal, then warming

By Ian Livingston

This weekend’s weather is going to bring near-normal temperatures to the area along with abundant sunshine. That spells fantastic conditions for any outdoor activities. It really only gets better heading back into the work week as well. Better if you like warmth, that is! Bottom line: One of the nicest weather stretches we can ask for is lining up quite well with all that foliage heading toward high color, or even peak out west.

Two key reasons why October often brings super-nice weather are: 1) Average high temperatures are in the sweet spot; and 2) Weather systems tend to scoot on by realtively quickly. We’ll see both factors at play over the next several days, with fine weather today into tomorrow, interrupted by a brief period of possible showers late tomorrow into early Friday, then clearing out nicely for the weekend.

Hurricane Hazel set Washington’s wind speed record; linked to fatal hurricane hunter crash

By Jack Williams

By mid-October the chances of a hurricane hitting the mid-Atlantic region are almost zero. It’s time to begin worrying about extratropical cyclones. Fifty-eight years ago on On Oct. 15, 1954, Hurricane Hazel set the sustained wind speed record at Washington’s National Airport. It eventually merged with an extratropical cyclone, and indirectly led to two Canadians being onboard the only hurricane hunter airplane to crash in a storm since hurricane flying began during World War II.

D.C. area forecast: More clouds, some drizzle today; better tomorrow

By Matt Rogers

After one more day today of late November normal highs, we expect to surge into the upper 60s and low 70s tomorrow. Mostly highs in the 60s with cool nights persist into the weekend, but there is a chance for another round of 70s by Sunday ahead of another weather system. And after some drizzle and light showers today and tonight, we should stay mostly dry through the balance of the week.

PM Update: Showers off and on through the night; cool and damp Tuesday

By Ian Livingston

Another chilled October day is coming to a close, and we’re set to cap it off with an increased shower threat. Highs that have ranged from near 50 to the mid-50s are about as cold as you’ll see this time of year -- for instance, D.C.’s record low maximum temperature for the day is 54 in 1910 (we’ve hit at least that today). The good news is clouds will keep temperatures from really plummeting tonight, though showers will ensure it’s rather raw.

D.C. area forecast: Strong cold front to end mild streak; cold and wet Sunday

By Ian Livingston

This weekend is a tale of two months, neither of which we’re currently in. Today’s highs are more like those we might expect in late September. Tomorrow we might have daytime temperatures like those we’d typically see in early December. Between the two is a strong cold front that kicks through this afternoon, followed by a little storm system passing by behind it. Rain associated with the storm promises to make tomorrow’s chill rather raw.

D.C. area forecast: Fog, showers depart, drier air moves in before big Sunday cold push

By David Streit

The dry air is on its way today but really takes until late in the day to convince us that it is here to stay. Tomorrow has nice day written all over it with a warm sun and low humidity. A mega-cold front coming out of the Midwest may hold off long enough to salvage most of Saturday. But Sunday looks like a bust with highs lucky to make 60 and possible showers.

By Ian Livingston

It ended up a bit cloudier today than expected, but that has not kept temperatures down much. Highs near and just above 80 are well above average for the date, and with humidity levels running high, it certainly doesn’t feel much like fall. We’ve got some more mild times ahead for the rest of the work week. Enjoy -- if you’re into that sort of thing!

After a beautiful start to the day, clouds have crept into much of the area, and they’ll continue to thicken and lower moving into the evening. Highs reaching near or above 70 are a bit cool for the beginning of October, but not too far from normal. We’ve got a mild and humid air mass heading in as a storm passes to our west. Rain is on the way too, but it might not end up being a lot.
