North American Weather (U.S.A & Canada)

Recommended Posts

Warmth on one side...and chilly on the other. 

 

Denver with it's second 5" snowfall in 3-4 days today - bit of a giveaway for the mile high city, but Wyoming, Utah, even Nebraska in for snow today. 

 

Great contrasts once again.

Hi everyone. In a week i will be in Ontario, so I am wondering, what is the best way to see the 850 and 500 in this region. Something like gfs in Europe?

January to yield winter's first outbreak of icy air in eastern, central US

Quote

This past November was one of the warmest on record in much of the Central and Eastern states. December is following in the footsteps of November, with temperatures averaging 6 to 12 degrees Fahrenheit above normal in many areas east of the Rockies.

While locked-in cold may still be weeks away, there are signs of more significant and more frequent visits from cold air east of the Rockies in January.

AccuWeather Chief Long-Range Meteorologist Paul Pastelok expects a partial change in the weather pattern to begin shortly after the start of the new year.

"We are not looking at a complete change in the pattern, but rather an easing of the bouts of record-breaking temperatures," Pastelok said.

Huge West/East split again through the US for christmas week. Record mild down the eastern seaboard and then there is literally a split down the centre of the country, toward the west where a whole list of states could receive a massive snowfall.

Headline: While the eastern US basks in another round of record warmth this weekend, the southern plains is under the gun for what could be the most ferocious snowstorms seen in years.

The models are coming into good agreement now with respect to the track and timing of an upper level low set to eject out of the southwest into the southern plains this weekend. As it does, it will fire up a surface low over eastern TX and tap into western Gulf of Mexico moisture. The combination of a deep, moist mid level southeasterly flow with a polar airmass driven down by strong northerly winds will set the stage for a memorable storm on Sunday into Monday.

Punishing Four-Season Storm Grips U.S. during the Holiday Week, Killing Over 40

Quote

An incredible variety of weather hazards made their presence felt over Christmas weekend across the central U.S., from blizzard to tornado to freezing rain to flash flooding and river floods. More than 40 weather-related deaths have been reported since Wednesday. The multi-day storminess is related to a gradual realignment of the large-scale pattern over North America. A stunningly warm, moist air mass across the eastern and southern U.S.--by some measures the most tropical on record for early winter--is in the process of being displaced by a strong upper-level storm across the West, bringing much more seasonable cold. There’s been so much remarkable weather over the weekend that it’s difficult to summarize in a single blog post, but here are some highlights.
