Remember I said watch for the blast around Sept 30th? Well... latest Euro says the blast isn't in the East and we get torched again. I hope its just a bad run otherwise I'll start using #NoFall





Same time frame this is the Jet stream pattern it has. Positive tilted Jet digging over the Rockies. Ridge peaking to Quebec in East. Poor Eastern Alaska in a ridge too.

The biggest difference is that trough in the West. Wasn't there the previous run which allow the cold air to spill more East instead but still wasn't over the Northeast. Each run has been weaker with the cold for Northeast.


Unreal. please be wrong

Lucky you got 60's. I won't see that until a good 3 or 6 weeks from now.

Not sure how realistic that run looks. Time will tell.

Meanwhile snow has returned to Edmonton. Currently 0°C and snowing. More on the way for the weekend before the warm up: perhaps 5-10cm for parts of central Alberta--more in the mountains.

Quote:
ALBERTA...THE FIRST OF TWO SNOWFALL EVENTS IS CURRENTLY BRINGING SNOW TO CENTRAL ALBERTA. TOTAL ACCUMULATIONS FOR THIS EVENT ARE EXPECTED TO BE 5 CM OR LESS.

RIGHT ON THE HEELS OF THE CURRENT SYSTEM IS A MUCH STRONGER SYSTEM THAT IS EXPECTED TO BRING 5-10 CM OF SNOW TO A WIDE SWATH OF CENTRAL AND SOUTHERN ALBERTA, FROM NORDEGG TO CORONATION. ALSO, OVER THE HIGHER TERRAIN IN BANFF NATIONAL PARK, ICEFIELDS PARKWAY, A FURTHER 15 CM OF SNOW CAN BE EXPECTED BY SATURDAY MORNING AND THUS A SNOWFALL WARNING HAS BEEN ISSUED. ALONG THE RAIN/SNOW LINE FREEZING RAIN IS EXPECTED SATURDAY MORNING FOR AREAS EAST OF CALGARY TOWARDS CORONATION.

SUNDAY, A WARMING TREND BEGINS AND A BREAK FROM AN EARLY START TO WINTER AS TEMPERATURES ARE EXPECTED TO RISE INTO THE DOUBLE DIGITS FOR MOST OF ALBERTA.

Seems to have been the pattern for the last couple of months that cool downs coincide with weekends. If the models are right we'll have another cool down next weekend. Still negative anomalies throughout.

We have a reasonable chance of breaking this record. We've already smashed the record for total amount of September snow.

Severe thunderstorm watch up. Expecting 100kph / 60mph wind gusts to be the main threat.

Temps are plummeting though. Temps down to 75F at ORD and 76F at MDW


We will most certainly be above average by the end of the month, but not nearly this month as the colder air is coming







The upcoming 5 days actually look about normal except for Saturday which looks to be on the cool side.

Average high/low at ORD for Sep 21st is 73F/52F




day 6-13 looks mighty chilly




and 11-15

Light to moderate snow in the Edmonton area this morning seems to be exceeding forecast accumulations.
