Hey and Hi Jets!

Aren't they lovely temps for spreading around and sharing ?!?

I have some people in Oakville that I think would really appreciate them. Want to help???

Look at that sharp polarization between the Midwest and the Southeast It's hot and humid in Florida ("July weather") and on the other hand, there are deadly, record-breaking wind chills in the upper Midwest.

Wind chills below -40 in parts of the Dakotas. Near -60F in Saskatoon I'm quite envious. How low will they go?

4:00AM Update
Temperature 68°F(20°C)/Dew Point 67°F(19°C)/Overcast
Feels like the summer vibe is back here in January lol this coming warm front invasion makes insane!!
High temperature would be around 75°F(24°C) today.

It's hovering at about the 0 celcius mark and raining pretty hard out there.... I think it's supposed to "warm up" this afternoon so hopefully a serious issue with ice will be averted, but then the temps are supposed to drop significantly.

One of those days I'm not sure what to post without flooding the thread. LOL

How about a tid bit from NWS NY NY discussion first and a map of the setup... Siberia Express!

NATIONAL WEATHER SERVICE NEW YORK NY
640 AM EST SUN JAN 4 2015

THE LONG TERM PERIOD WILL BE DOMINATED PRIMARILY BY AN ARCTIC
AIRMASS...THE COLDEST TIME PERIOD EXPECTED TO BE WED NIGHT AND THU.

A BROAD TROUGH WILL REMAIN IN PLACE ACROSS THE EASTERN US THROUGH
THE WEEK COURTESY OF A LARGE VORTEX CONTINUALLY SPINNING OVER
EASTERN CANADA/CANADIAN MARITIMES.

THIS WILL SET UP THE SIBERIAN EXPRESS AN AIR FLOW TAKING A NEARLY STRAIGHT PATH FROM SIBERIA OVER THE NORTH POLE THROUGH CANADA AND INTO THE EASTERN HALF OF
THE COUNTRY DUE TO THE AFOREMENTIONED VORTEX AND AN RIDGING OVER
ALASKA AND WESTERN CANADA/US. THIS WILL SET THE STAGE FOR A VERY
COLD AIRMASS TO INFILTRATE THE REGION DURING THE MIDDLE OF THE WEEK.

WED-THU...UPPER TROUGH AMPLIFIES AS 160KT H3 JET DIVES DOWN THE
BACK SIDE TUE NIGHT. SOME SHOW SHOWERS/FLURRIES ARE POSSIBLE
DURING THE DAY ALTHOUGH THE ENERGY ALOFT IS SHEARED SO ANY
PRECIPITATION WILL MOST LIKELY BE JET INDUCED. MORE
IMPORTANTLY...THIS WILL BE THE TRANSPORTER OF THE COLDEST AIRMASS
OF THE SEASON FOR WED NIGHT/THU. NOT ONLY WILL IT BE COLD...BUT
WINDS COULD BE QUITE GUSTY WITH THE POTENTIAL FOR WIND CHILLS TO
FALL BELOW ZERO AT MANY LOCATIONS...AND EVEN WIND CHILL ADVISORIES
POSSIBLY BEING NEEDED ACROSS THE INTERIOR. LOWS WED NIGHT WILL
FALL INTO THE SINGLE DIGITS WITH HIGHS IN THE TEENS TO AROUND 20
ON THU. IF THERE IS ANY SNOW ON THE GROUND FROM TUE EVENT 5
DEGREES MAY NEED TO BE KNOCKED OFF CURRENT FORECASTED TEMPS.

Split Vortexes.
Southeast(or Atlantic) ridge getting nudged East.
Western Ridge leaving the door open for a trough to dig down.
Or, I like to see it as, a trough strong enough to push the SE Ridge away. (usually in winter they are strong enough to push southward and be amplified)
Blues are -25C+. Very cold airmass.

20-30 below in January. Something I always hope for when we're in summer. For here means Perfect but I feel bad for midwest..




This morning wind chills. F°

Atlanta might see a below freezing high mid week, a very rare sight. I'm not sure the locals will be prepared.

Atlanta average two days at or below freezing annually. I'm sure they'll be fine.

Great Lakes Cutter storm leaves, Clipper moves in. Perfect track for me!

But don't forget the Appalachians effect on small storms. Usually weakens them! We'll have to see if a coastal storm can develop to re-strengthen things. Doesn't look likely.
