Whistling Winds to Wane Early this Week
Active (wintry?) weather likely late week
Jason Samenow @ 11:00 AM
Strong winds, which have caused thousands of area power outages, will continue to rake the region today -- but won't be as strong as last night. Calmer and milder conditions will build into the region for mid-week. Very unsettled weather is possible Thursday through Sunday as two separate storm systems potentially affect us.
Mostly sunny, windy and cold. Strong northwest winds will blow in very chilly Canadian air. High temperatures are likely to be around 40, but factoring in 20-30 mph winds, it will feel like the 20s (even some teens early in the morning) for most of the day. Tonight, the winds will subside, but temperatures will plummet under clear skies. Lows should range from 16-24 (suburbs-city).
Mostly sunny, calm winds and not as cold. High pressure drifting over the region will promote plenty of sunshine and shut down the winds. The chill in the air will also moderate, with high temperatures 5-8 degrees warmer than today, ranging from 44-48. Partly cloudy skies overnight, with lows 26-31 (suburbs-city).
Increasing clouds, seasonably cool. A weak cold front to the northwest will gradually slide towards the region (and through the region overnight), with cloud cover building out in front of it. Meanwhile, low pressure will likely develop to the southwest (with implications for Thursday and Friday's weather, see below) Despite mild southerly flow ahead of the front, the clouds should hold high temperatures close to their seasonal norms -- in the mid to upper 40s.
Winds yesterday took a while to get going, but by late afternoon, many areas we're experiencing gusts well in excess in 40mph. BWI Airport had a peak gust of 61mph and Reagan National gusted up to 49mph. The winds knocked down trees and power lines, which may have been weakened by ice in some spots north and west of DC.
Speaking of ice, accumulations mainly occurred to the west, southwest and northwest of Fairfax and Montgomery Counties. Totals were generally on the order of several tenths of an inch.
Check in around 11am to see some very scenic photographs of the ice in the Blue Ridge and Shenandoah Valley.

Increasing clouds, seasonably cool. A weak cold front to the northwest will gradually slide towards the region (and through the region overnight), with cloud cover building out in front of it. Meanwhile, low pressure will likely develop to the southwest (with implications for Thursday and Friday's weather, see below) Despite mild southerly flow ahead of the front, the clouds should hold high temperatures close to their seasonal norms -- in the mid to upper 40s.A Look Ahead
- On Thursday, an area of low pressure to the southwest will approach the area, with some form of precipitation likely beginning in the afternoon. Said low pressure is currently forecast to redevelop off the Carolina coast -- with precipitation continuing through midday Friday. Once again, precipitation type is a big question mark and will depend on the track of the low pressure areas as well as the amount of cold air to the north. It's too early to make a call on precipitation type but we'll keep you posted. High temperatures both Thursday and Friday should be near 40, with lows near freezing.
- A break in the action should occur on Saturday, with partly sunny skies and highs in the mid to upper 40s.
- On Sunday, a strong cold front is likely to approach and pass through the area, with rain initially, which may change to snow briefly before ending. Highs should be in the 40s, but may well drop after the front passes. Details on this scenario are very murky, so stay tuned.
