Today: Breezy and cold. 29-33. | Tonight: Clear and cold. 14-20. | Tomorrow: Partly to mostly sunny. Cold. 31-35. | A Look Ahead | Get Express Forecast by E-mail


There will be no escape from our persistently cold weather pattern this week. Since this season's first snow on December 5, only a handful of days have been warmer than average. This week, there won't be any. Many of us could probably deal with the cold without the wind. Fortunately, the wind will relent after today. At least through mid-week, the cold pattern will be a dry one before a chance of snow Thursday night into Friday.

Strong low pressure off the New England coast continues to sit and spin. The difference in pressure between this storm and high pressure to the west continues to generate strong winds.

Today (Monday): The deep storm off the New England coast, responsible for our windy weekend, will continue to circulate some gusty breezes (in excess of 20 mph) southward as it pulls away today and high pressure builds in from the west. So, for one more day, wind chills will be very low...possibly starting the day in the single digits. As air temperatures climb through the 20s in the afternoon (under partly sunny skies) and winds let up some, wind chills will rise into the teens. A few snow flurries are possible (20% chance) mainly this afternoon. Confidence: Medium-High

Tonight: It will be mostly clear and cold. Lows will range from the teens (suburbs) to low 20s downtown. Winds will drop to between 5 and 10 mph. Confidence: Medium-High

Keep reading for the forecast through the week...

Tomorrow (Tuesday): Under mostly sunny skies and lighter winds (from the northwest around 10-15 mph), temperatures will likely get above freezing for the first time since last Friday. Highs should reach the mid-30s. Confidence: Medium-High

Tomorrow Night: Another clear and cold night, with lows ranging from the upper teens (suburbs) to mid-20s (downtown). Confidence: Medium-High


Wednesday and Thursday will both be partly to mostly sunny and chilly. Highs both days will be in the mid-to-upper 30s with lows in the high teens to mid-20s. Though these temperatures are below average, it will feel relatively mild compared to recent days since there will be noticeably less wind. Confidence: Medium-High

Thursday night into Friday, a clipper will swing by to our south, possibly (40% chance) producing a period of light snow. There is just a slight (less than 20%) chance that this clipper will redevelop into a coastal storm and produce significant snow. Friday highs should range from 30 to 35. Partly cloudy, windy and cold Friday night with lows from the teens to near 20. Confidence: Low-Medium

Next Saturday should be just like the last Saturday: windy and very cold. Highs will probably only be in the 20s under partly to mostly sunny skies. Breezy and cold Saturday night, with lows in the teens. Confidence: Medium

Winds should diminish some on Sunday, but it will remain cold, with highs struggling to near freezing. Confidence: Medium

Updated: Monday Jan. 4 @ 11:15 a.m.

How will our so called "scientists" HIDE THE DECLINE?

What are we talking in terms of snow accumulation on Friday? A decent storm or a freaking annoyance?

Posted by: authorofpoetry | January 4, 2010 9:32 AM | Report abuse

Even Howard Bernstein on Ch 9 has a lot of skepticism on the late week storm, and Ch 9 generally is one of the snow "hype" outlets. Said a slight chance of light snow, but admitted he's even skeptical of even light snow at this point.

Fact of the matter is, when the Arctic blasts start coming our way, we usually only see clipper type snows that produce an inch or 2 at the most.

For the last time, environmental concerns are reflected in extreme weather patterns. The "coldest" the "worst snowstorm" etc are extreme weather patterns. We have heard from you all before and you never say anything new so please stop.

Now, let us go back to our weather nerd fest.

Leaning toward (at most) a "freaking annoyance," ... however, it's only Monday and we're talking Thursday night or Friday, so a lot can (and often does) still happen.

Your failure to understand the difference between weather and climate is stunning, albeit predictable.

Ok Christmas is over, I am ready for SPRING, this weather is driving me crazy :-0. It's just too cold. Doesn't look good (to me) for the forseeable future though. Even Accuweather has it cold for several weeks. Great for the skiers! I'll bet the ski resorts around here are doing their happy dance this year. I wonder what the meteorological hinge date is for the avg. temps to begin their slow climb back up? I would figure it to be around the 21st or so of Jan.

It is literally too cold to snow right now. This is an amazing stretch of weather this year. While I do not agree that "extremes" relate to overall climate changes, it is clear that this winter is off to a cold start.

@Tom8: Is it ever really "tool cold to snow?" Doesn't it get this cold (and more) at the poles, and do they not have an abundance of the white stuff?

@ItsOver2: That's weather. You're mixing your metaphors again.

Now Tom, I dont know about that. We're actually warmer out now than we were during our great blizzard a few weeks back.

Looking like a great setup for some outdoor ice-skating possibilities this weekend.

First of all, I really enjoy reading the posts on Capital Weather Gang. I find them very informative. I'm also a subscriber to the professional website where I get Joe Bastardi's views on the upcoming weather. Joe has been predicting a pretty big snowstorm for this area since last Thursday. He said that the GFS model is making it's usual mistakes, but will figure out what's coming when we get closer to the storm on Thursday. Just wanted to give people another view of what's coming on Thursday into Friday.

Yes, it seems that the NWS is also a little more concerned about the Thursday/Friday storm than the Capital Weather Gang. If you can decipher the shorthand, you read their take here as well:

It's never really "too cold to snow", but cold air holds far less moisture than warmer air. Hence there's generally less snow when the air is colder.

I'm sure it will not change the minds of those who irrationally see a few cold days at some selected locations as a decline in global temperatures. But facts count. MSU satellite data indicates that warmer than normal regions continue to offset - and then some - the areas of below normal.

As an example, recently I noticed that Verkhoyansk, Siberia was reporting light snow with a temperature of 26 below zero, Fahrenheit. Snow at this temperature should be very light and the snow/water ration would be very high, perhaps 20:1, meaning twenty inches of snow for each inch of precipitable water.

Obviously, air in Verkhoansk or Oymyakon can hold very little precipitable water at these termperatures, but it can still snow whenever the relative humidity hits 100%. However it's more likely that the moisture may precipitate as ice crystals from "ice fog" at such temperatures.

One thing not said in this discussion and in lots of the other talk re: global warming is that overall the earth could be heating up; but there will be pockets where things can be cooling down. It's very possible that the Mid-Atlantic USA will be having colder temperatures due to ocean/air currents being modified by overall global warming. Don't some of the global climate change models call for this area to become significantly cooler (until overall global warming is so great it overwhelms the factors making for those colder pockets?)

Fact: The sky began growing darker late this afternoon.

Fact: The U.S. Naval Observatory confirmed that the sun "set" at 4:59 p.m. today in Wshington.

Fact: The sky continues to grow darker.

How will our so called "scientists" HIDE THE FACT THAT WE ARE LOSING THE SUN?

Wait: Maybe we can't trust the U.S. Navy: It's been taken in by the global warming hoax. See:
