  Snow for Some, then Cold for All

  Feb 10, 2012; 8:11 AM ET

  The cold will be quite noticeable, especially because it has been such a mild winter overall. The map following the video is our basic snow forecast map. These maps are updated day and night, so keep in mind this one was made early Friday morning.

  Two-Day Cold Shot on the Way

  Feb 9, 2012; 7:59 AM ET

  The scene outside the AccuWeather building was more wintry this morning than it has been most of the season.

  Snow Twice in Four Days?

  Feb 8, 2012; 9:44 AM ET

  There is a chart that we use that can be helpful in snow predictions. This will sound ridiculous but it is often useful. On our pro site, we plot a 200 mb map analysis. At that altitude, troughs are warm and ridges are cold... the opposite of what we find at lower altitudes, like the 500 mb level at around 18,000 feet.

  Winter Stirrings

  Feb 7, 2012; 8:51 AM ET

  Tomorrow's system will be no trouble if all the precipitation is over before the cold air comes in. However, all it would take is a drop below freezing and a small amount of rain changing to snow, and suddenly there are problems all over the place.

  Weather Persons' Day

  Feb 6, 2012; 10:23 AM ET

  Yesterday was weatherperson's day, marking the birth of one of the first weather prognosticators, John Jeffries, on this date in 1705. In our work, we're under high pressure to help people weather the storms of life, and sometimes offer a bit of philosophy.

  Milder, then Colder

  Feb 6, 2012; 8:31 AM ET

  Last year, when blocking developed over the Arctic, the prevailing westerlies were forced south of their usual path. Forecasts for a cold winter were based largely on that happening again. However, that has not happened, and the latest upper stratospheric flow charts do not signal any major changes over North America. In short, the weather is much more peaceful than usual, considering this is the heart of midwinter.

  Snow Drought Continues in the Northeast

  Feb 4, 2012; 2:05 PM ET

  A fragment of the storm that caused blizzard conditions parts of the eastern Rockies and High Plains sent some snow into parts of Ohio and southern Pennsylvania today. This system will continue eastward

  Extreme-Free Outlook

  Feb 2, 2012; 8:01 AM ET

  Last year, my wife and I were in Punxsutawney for the big day. Another fascinating place in that town is the Weather Discovery Center. In this picture, I got a closeup view of the groundhog ceremony. Punxsutawney Phil predicted six more weeks of winter this morning, but one very perceptive tweet asked how we can have six MORE of something that we haven't six OF so far this season.

  Pattern Change Coming

  Feb 1, 2012; 8:43 AM ET

  Unfortunately, it is not clear to me exactly where the results of these signals should or will show up. When we last saw a high pressure area in western Canada, it was followed by extreme cold in parts of Europe and central Asia, but not in the Northeast U.S. You can see the changes that occurred between January 23rd and last night.

  Where is Winter?

  Jan 31, 2012; 10:12 AM ET

  Behind the front, the air is not as cold as in a typical winter airmass, but as the ground hog appears at Punxsutawney Pennsylvania on Thursday morning, there will be a chill in the air again. Here is an indoor picture of the famous ground hog that I took last year:

  Winter in the Shadows for Groundhog Day

  Jan 30, 2012; 8:05 AM ET

  On this upper air flow forecast for NEXT Thursday, you can see a low pressure area just north of Lake Superior. Such a feature would bring cold air from central Canada across the Great Lakes and into the Northeast.

  Colder Weather to Unfold, but the Cold Will Fold Again

  Jan 27, 2012; 7:28 AM ET

  While a couple of weak fronts will move across the Northeast between tomorrow and Monday, the one most likely to cause some snow showers (again talking about the I95 corridor, where snow flurries are relatively rare) is one that should arrive late Sunday or Sunday night.

  Rain Moves toward the Northeast

  Jan 26, 2012; 7:54 AM ET

  The dental drill was patented on this date in 1875. Will this be the winter when we look back and say the snow nevacaine (I know, that's not how you spell novocaine, but that's how it came out when the hygienist was working on my teeth. Don't they always ask questions when you cannot really talk?).

  Next Storm to Bring Rain Except in Northern New England

  Jan 25, 2012; 8:21 AM ET

  This is National Certified Registered Nurse Anesthetist Week and lasts until the 28th when they finally put it to sleep. It commemorates the fact that nearly 2/3 of the surgical anesthesia in this country is administered by such CRNA's. At this point on a Wednesday, people are more concerned with us taking a shot at how the weather might affect their operations.

  Harsh Wintry Cold Unplugged

  Jan 24, 2012; 7:56 AM ET

  Andre Ampere, founder of the science of electrodynamics, was born in France this week in 1775. The very next year the American colonies decided to re-volt. In the weather department, some people will really got a charge out of the recent warm up, especially after the shock of cold we had for awhile last week.
