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

[Roger J Smith]

Rich, looking at the charts, I would say mostly cloudy, brief sunny intervals, passing showers that will fall as snow even at valley elevation, except sleety mix possible around mid-day heating max in lower elevations, but showers won't be too prolonged in valleys, could see 5-10 cms snow on higher slopes though, and highs both days 7-9 C, morning lows 2-4 C. This would be for Canmore, for Edmonton less cloud and shower activity and a somewhat lower temperature trend. We're getting rain here this morning.

Anyway as you know the weather can be very changeable in the mountain valleys from place to place, with all the different upslope and downslope processes going on. But the air mass looks to be partly cloudy, unstable and rather chilly compared to recent weeks although near normal for time of year.

Roger you are pretty much spot on. Woke up this morning to the first covering of the season, only about 1 cm here in the Valley but higher up it was closer to 5cm. Nice and sunny now with the remaining snow slowly melting in the sun

[cheeky_monkey]

Looks like another sunny and relatively mild week ahead..no snow in the forecast up to and including the end of October..which i think is rather unusual.

[Coopsy]

Very snowy yesterday for a few hours - a few inches on trees and grass etc. Minus 7oC this morning and very icy on the roads

[knocker]

Area of snow around Denver at the moment associated with a low pressure area.

[knocker]

Snow at the moment in NW Texas. You can see the division between the cold and warm air quite clearly on the Amarillo radar.

[knocker]

Latest on the snow in Texas from the Lubbock radar.

US and Canada midday surface chart. Some snow in Ontario and the Prairies.

Edited October 28, 2011 by weather ship

[knocker]

Some snow this morning in W. Virginia and Pennslyvania. Borderline looking at the Charleston radar.

[knocker]

Quite an extensive area of snow now in Pennsylvania. Giving the forecasters a bit of a headache I should imagine as looking at the temps it must be borderline snow or rain.

[knocker]

Major snow warning has been issued.

URGENT - WINTER WEATHER MESSAGE

NATIONAL WEATHER SERVICE GRAY ME

524 AM EDT SAT OCT 29 2011

...POTENTIALLY DAMAGING AND HISTORIC OCTOBER SNOWSTORM LIKELY FOR

TONIGHT INTO SUNDAY...

.LOW PRESSURE WILL RAPIDLY INTENSIFY AS IT MOVES UP THE MID

ATLANTIC COAST TODAY. THE LOW WILL PASS BY CAPE COD TONIGHT WHILE

STRENGTHENING RAPIDLY AND MOVING NORTHEAST.

PRECIPITATION SHOULD QUICKLY OVERSPREAD THE REGION FROM SOUTH TO

NORTH STARTING IN THE AFTERNOON HOURS ACROSS SOUTHERN NH AND

SOUTHERNMOST MAINE. THE LEADING EDGE OF THE SNOW SHIELD WILL

QUICKLY ADVANCE NORTHWARD DURING THE EVENING HOURS. TEMPERATURES

NEAR THE GROUND ON THE COASTAL PLAIN WILL PROBABLY BE WARM ENOUGH

FOR THE PRECIPITATION TO START AS RAIN OR A RAIN SNOW MIX...BUT

ONCE HEAVIER PRECIPITATION STARTS FALLING...ANY RAIN SHOULD FLIP

OVER TO HEAVY WET SNOW. THE CHANGE TO SNOW WILL PROBABLY BE

DELAYED A BIT LONGER ALONG THE IMMEDIATE COAST GIVEN THE

RELATIVELY WARM WATER TEMPERATURES THIS TIME OF YEAR.

THE EXPECTED HEAVY AND WET NATURE OF THE SNOW WILL STICK TO TREES

AND LIKELY CAUSE BRANCHES TO BREAK...ESPECIALLY ON TREES THAT

STILL HAVE LEAVES. EVEN JUST A FEW INCHES OF WET SNOW CAN CAUSE

SMALLER BRANCHES TO START BREAKING. EVENTUALLY...WITH ENOUGH SNOW

AND SOME WIND...ENTIRE TREES COULD SNAP. THIS WILL CREATE A

SITUATION WHERE THE POTENTIAL EXISTS FOR WIDESPREAD POWER

OUTAGES. RESIDENTS SHOULD PREPARE THEMSELVES FOR THE POSSIBILITY

OF EXTENDED POWER OUTAGES. ROADS WILL ALSO BECOME SNOW COVERED

AND TREACHEROUS.

THE STORM WILL MOVE OUT SUNDAY MORNING...BUT IT WILL REMAIN COLD

AND WINDY IN THE WAKE OF THE SYSTEM.

Snowing in NYC!

Cams 4 and 7 are probably best.

October temperature record is about to go, 32F at 1pm, the record is 31F.

Another 6-8 hours of snow expected.

This is epic, i am so living there for a year.

West Virginia at 10 inches.

Highest totals however are expected in New York and New Jersey.

[Updraft]

This is crazy even for New Yorkers. crazy weather in the US in recent days with snow even in the Texas panhandle.

[summer blizzard]

Bloomin New York!

Here i was earlier today thinking that i may begin to get snow withdrawals if we do not get any in November, to find that a record event is already in progress over NYC.

Such a great place for big snow events as well because they are really well documented.

Just hoping for some more pics.

This is crazy even for New Yorkers. crazy weather in the US in recent days with snow even in the Texas panhandle.

It's actually part of the same jet streak, its just that when you get near NYC you get moisture and a huge thermal gradiant thrown into the mix.

Parts of New Jersey are already without power.

[Aaron]

For perspective, New York has warmer October's then we do. No fair!

(at least we're getting our snow fix though eh)

[summer blizzard]

If anybody came came because they clicked the link in the seasonal section, can they just let me know as it may be a good idea to do it more often when massive snow events occur.

For perspective, New York has warmer October's then we do. No fair!

Yes, its great. Just like hearing from the people in the Midlands last December.

Even if its not snowing here, it's still a bit exiting to be able to monitor a big event elsewhere.

[Aaron]

Yup it's pretty exciting

Parts of Maryland have 7 inches so yes this is going to be record breaking for the NE USA.

Thanks for posting link to cams, nice early start to winter for those in the NE US. Some spots expecting around 12 inches of snow, which is very impressive.

Also some pics here: http://www.accuweath...snowstorm-i.asp

[summer blizzard]

Recent Accuweather prediction. Anybody in the 6 inch and above area stands a good chance of breaking local records.
