Starting from October? That would be something huh. lol #Doubt I remember northern Maine started their snowpack in November and never saw grass until April or something last winter.




Loop past 4 hrs. Snowing as far south as the Sierra now. Great Falls area getting hammered! 36hrs of snow now? More snow entering Washington. Rain for North Dakota.





Check out how far south the Jet stream is! Below normal in Southern California this morning.


Upper Low is larger and still centered over Washington & Oregon. Slow moving.

NWS Great Falls reports 9.7" fell yesterday to midnight (subject to change)


That would make it the 3rd snowiest September there. Normal is 1.2"


Also....It's the most snow that fell in 1 day before Halloween(Oct 31).


And it snowed more after midnight so they should be nearing a foot now.

No snow in Edmonton. Too far north!

I can't remember a system with this much energy in the autumn before. This would be unusual even for spring. Here's the Alberta weather discussion.

FOCN45 CWWG 291200
SIGNIFICANT WEATHER DISCUSSION ISSUED BY THE PRAIRIE AND ARCTIC STORM PREDICTION CENTRE OF ENVIRONMENT CANADA AT 7:00 AM CDT SUNDAY SEPTEMBER 29 2019.

ALERTS IN EFFECT... WINTER STORM WARNING FOR SOUTHWESTERN SASKATCHEWAN. WINTER STORM AND SNOWFALL WARNINGS FOR SOUTHERN ALBERTA. MORE FROST ADVISORIES FOR THE PRAIRIES EXPECTED LATER THIS AFTERNOON.

SYNOPTIC OVERVIEW... ALOFT THERE IS A STRONG UPPER LOW OVER THE NORTHWESTERN STATES, CURRENTLY NOT MOVING BUT FORECAST TO MOVE UP OVER THE CYPRESS HILLS AND START WEAKENING ON MONDAY. STRONG UPPER RIDGE OVER THE EASTERN PACIFIC UP THROUGH EASTERN ALASKA. UPPER LOW NEAR CORAL HARBOUR WITHIN A LONGWAVE TROUGH TO ANOTHER UPPER LOW NEAR MOULD BAY. UPPER HIGH OVER GREENLAND DEFLECTING THE ARCTIC STREAM WELL TO THE NORTH.

AT THE SURFACE EARLY THIS MORNING THERE IS A HUGE AREA OF HIGH PRESSURE, WITH ONE RIDGE OVER THE EASTERN PACIFIC AND THE OTHER FROM NORTHERN BC ACROSS THE NORTHERN PRAIRIES, NORTHERN ONTARIO AND SOUTHERN QUEBEC. 996 MB LOW NEAR THE TRI-BORDER AREA OF UTAH, WYOMING AND COLORADO ON A FRONTAL WAVE WITH TROWAL WRAPPING NORTHWARD AND WESTWARD. 1001 MB LOW NEAR IVUJIVIK CONTINUES TO WEAKEN AS IT TRACKS EASTWARD.

DISCUSSION...

EASTERN PRAIRIES... DEEP SLOW MOVING LOW WILL GIVE SNOWFALL TOTALS OF 30 CM OR MORE OVER SOUTHWESTERN SASKATCHEWAN WITH AMOUNTS GRADUALLY LESSENING AS YOU GO NORTHEAST. AS NOTED IN PREVIOUS DISCUSSION, WINTER STORM WARNINGS MOST LIKELY TO VERIFY, HOWEVER WITH WINDS OF 50 G 70 A BLIZZARD IS NOT OUT OF THE QUESTION. RAINFALLS TOTALS OF 20 TO 40 MM WILL AFFECT SOUTHEASTERN SASKATCHEWAN THROUGH SOUTHERN MANITOBA. RATIO OF RAIN TO SNOW BECOMES INCREASINGLY PROBLEMATIC FURTHER NORTH AND EAST, WITH THE MAIN CONCERN BEING FOR TONIGHT. POTENTIAL FOR REGINA TO GET WARNING LEVEL SNOWFALL TONIGHT AND INTO MONDAY MORNING, BUT RAIN/SNOW MIX AND SURFACE MELTING COULD REDUCE ACCUMULATIONS. FURTHER EAST, ONLY THE HIGHER ELEVATIONS OF WESTERN MANITOBA MAY SEE MUCH IN THE WAY OF SNOWFALL ACCUMULATIONS. THERE IS A GOOD POSSIBILITY THAT WARNINGS WILL EXPAND NORTHWARD AND EASTWARD OVER SOUTHERN SASKATCHEWAN AT SOME POINT TODAY, BUT MOST LIKELY THE EXPANSION WILL BE IN THE FORM OF A SNOWFALL WARNING AND NOT A WINTER STORM WARNING SINCE THE NORTHEASTERLIES WILL BE DIMINISHING BY THE TIME THE HEAVIEST SNOW ARRIVES.

REGIONS BEYOND THE NORTHERN EDGE OF THE SNOW WILL SEE FROST TONIGHT, WITH ADVISORIES COMING WITH THE AFTERNOON FORECAST UPDATE. AS A NOTE, THE LAST FROST ADVISORIES OF THE SEASON, IF NEEDED, WILL BE ISSUED MONDAY AFTERNOON.

KIVALLIQ... STRONG NORTHWEST WINDS PERSIST, ALBEIT NOT AT WARNING LEVELS. THE SYSTEM WHICH IS NOW NEAR IVUJIVIK WILL CONTINUE TO WEAKEN OVER THE NEXT DAY OR SO, WITH NORTHWEST WINDS SLOWLY DIMINISHING IN ITS WAKE.

WESTERN PRAIRIES...EASTERLY UPSLOPE FLOW WILL CONTINUE TO PRODUCE HEAVY SNOWFALL ALONG THE SOUTHERN FOOTHILLS AND MOUNTAIN PARKS TODAY. THE HEAVY SNOWFALL HAS PUSHED INTO THE CALGARY REGION AND WILL MOVE INTO THE AIRDRIE AND DRUMHELLER REGIONS THIS MORNING. AS A RESULT, THE SNOWFALL WARNING HAS BEEN EXPANDED TO INCLUDE THOSE AREAS. DUE TO THE LONG LIVED NATURE OF THE FLOW REGIME, SNOWFALL AMOUNTS IN THOSE AREAS MAY APPROACH 25 CM BY MONDAY AFTERNOON. THE LATEST MODEL RUNS PERSIST IN GIVING EXTREME AMOUNTS NEAR 100 CM OVER THE HIGHEST TERRAIN BY MONDAY AFTERNOON. LATE ON MONDAY THE ENERGETICS OF THE UPPER FLOW WILL SHIFT INTO SOUTHERN SASKATCHEWAN AND THE SNOW SHOULD FINALLY END OVER ALBERTA.

FROST ADVISORIES ARE LIKELY OVER MUCH OF NORTHERN AND CENTRAL ALBERTA FOR OVERNIGHT. MODEL TEMPERATURES FOR CENTRAL ALBERTA MAY NOT BE COLD ENOUGH IF SKIES CLEAR OUT EARLY IN THE EVENING. SOME REGIONS MAY SEE OVERNIGHT LOWS CLOSE TO THE MINUS 10 DEGREE MARK. THE FROST ADVISORY PROGRAM ENDS SEPTEMBER 30.

HIGH ARCTIC...NO ACTIVE WEATHER IS EXPECTED OVER THE HIGH ARCTIC TODAY. WITH COOLING TEMPERATURES AND OPEN WATER IN MANY COASTAL COMMUNITIES, THERE IS A RISK OF FREEZING DRIZZLE AT A FEW LOCALES.

Too bad that low couldn’t make its way down to Texas! We could use some cool weather and rain.

Yeah, there's a pretty impressive contrast between the weather in the NW and SE parts of the country right now.
