December 2011 General Discussion/Obs


Chicago Storm

Recommended Posts

Yeah it sure has been persistent for the last few days. Looks like the models generally agree on cutting off the southern vort for a few days before finally lifting out after 160hrs. The evolution of the upstream vort is gonna be key on how this all goes down. The Euro has done really well lately, so hopefully it's on to something with a less "torchy" ejection of the southern vort.

Yeah, I'm not convinced that so much energy would be left behind... however it always seems like the progressive solution ends up working out.

If only we could get those two waves to phase and kick out right away..

Yup. And that confluence south of James Bay would probably prevent a toasty warm solution.

You can tell there's a lot of spread but there EURO ensembles seem to have something around 168-192 in the OV, just like the OP run. And just like the OP EURO, the mean, if anything, it's a little too far south for us. Nothing like the torch storm the GFS is advertising

Part of this afternoon's Long-Range Area Forecast Discussion from the NWS in Northern Indiana...

SUN-MON...INCREASING CHANCES FOR PRECIP AS AN ACTIVE NORTHERN

STREAM INTERACTS WITH ANOTHER SW CONUS UPPER LOW. ADVECTION

TIMING/THERMAL FIELDS/AND HEIGHT FALL DEPTH INTO THE REGION IS

STILL MUCH UNCERTAIN. HAVE OPTED FOR THE LOWER SIDE OF CONSENSUS

BLEND...WHICH SUPPORTS LOW CHANCE POPS...WITH A RAIN OR SNOW MENTION

PREFERRED FOR NOW. EXPECT FURTHER ADJUSTMENT IN THIS PERIOD.

That writeup by Gaylord says it best.

Very grim winter. What's it going to take to get rid of la Nina and el Nino.

Well it gets even better.

NWS WFO Gaylord Mi evening AFD. 12/12

TUESDAY NIGHT THROUGH NEXT MONDAY...AS HAS BEEN THE CASE OVER THE

LAST FEW WEEKS REALLY...THERE STILL DOES NOT APPEAR TO BE A MAJOR

SHIFT IN THE LARGE SCALE PATTERN THROUGH THIS PERIOD. THE PATTERN

REMAINS PROGRESSIVE WITH THE BULK OF THE ARCTIC AIR REMAINING WELL

TO OUR NORTH ACROSS THE FAR REACHES OF NORTHERN CANADA WHILE THE

DOMINANT STORM TRACK REMAINS TO OUR WEST. THE FAIRLY STRONG AND WELL

ADVERTISED STORM SYSTEM MOVING OUT OF THE SOUTHWEST (CURRENTLY

EVIDENT ON WATER VAPOR LOOP ACROSS SOUTHERN CALIFORNIA) WILL BRING

PRIMARILY LIQUID PRECIPITATION TO THE REGION WEDNESDAY INTO EARLY

THURSDAY. COLDER AIR ON THE BACKSIDE OF THIS SYSTEM WILL THEN BRING

THE CHANCE OF SNOW SHOWERS THURSDAY AFTERNOON RIGHT INTO SATURDAY.

EXTENDED MODELS OVER THE LAST COUPLE OF DAYS HAVE BEEN HAVING A

DIFFICULT TIME DECIDING THE AMOUNT OF MOISTURE AVAILABILITY...WITH

LATEST INFORMATION INDICATING THAT THERE WILL BE A BIT MORE THAN

PREVIOUSLY ADVERTISED WHICH IS STILL ON THE LEAN SIDE. WE MAY SEE A

BRIEF BREAK IN THE ACTION SATURDAY NIGHT INTO SUNDAY AS HIGH

PRESSURE BRINGS IN MILDER CONDITIONS. HOWEVER...ANOTHER STORM SYSTEM

WILL THEN LIKELY TRACK BY TO OUR WEST EARLY NEXT WEEK (PERSISTENCE)

BRINGING ANOTHER CHANCE FOR PRIMARILY RAIN. THE MAIN LONG TERM

FORECAST CONCERNS REVOLVE AROUND POPS AND THE TYPE OF PRECIPITATION

THROUGH THE PERIOD...AS WELL AS THE EXTENT OF LAKE EFFECT THURSDAY

AFTERNOON THROUGH SATURDAY.

Always have respected and admired the Gaylord office for their winter pattern talk.

Larry Cosgrove throwing a bone. Pattern change ahead.

The weekend storm is very important for many reasons. If this feature turns into a strong cyclone as I think it might, colder air will be pulled southward through the Great Plains. On the idea that a cAk vortex forms as the low enters S ON and QC, then a veritable pattern change could occur where colder values have a grip on the U.S. to the right of the Continental Divide. With a huge stratospheric warming event forecast across Arctic Canada and the ever-vigorous southern branch jet stream supplying moisture and energy, Texas and the Gulf Coast could get stuck in a frequently wet and cold alignment during the last week of December.

Keep your eyes on the weekend. Because a minor storm could very well translate to a milder winter outlook for many. Then again, if the low pressure area is as intense as I think it may be, a while new world of weather awaits us, beginning with the holidays!

We probably are looking at a mid January start to winter.

By start of winter I mean highs below 30 and lows below 15 for weeks on end.

Gaylord usually has highs below 25 and lows in the single digits with 12-24 inches base by the 1st of January.

Yeah...to say this pattern is getting old is an understatement. Just 9.8" of snow for the season here in Gaylord, with not a hint of anything left, and highs well into the 40s both yesterday and again today. Nothing looks very promising the next 10 days either. Snowmobile/ski industry taking a big hit right now.

The lack of snow has become something of a joke in the office.

That's a good bone! Good to hear the possibility that this season might turn around. Believe it when I see it though!

Looks like the GEM is onto some Great Lakes snow around D6.
