buckeye Posted December 23, 2012 Share Posted December 23, 2012 Living in Central Ohio for 20 years I would agree with this statement. This system looks very much like several I have seen before where the low pressure center passes near the Ohio/WV border before jumping to the East Coast. The rain/snow line sets up NW of Columbus, and the greatest snowfall amounts end up from Indy to FWA/Lima and Toledo. I won't concede completely until the 00z runs tonight....but this post is 100% spot on... unfortunately. Yes, I could see an indy to toledo special on this very easily as well. I just want to see Dr. No say it first. Link to comment Share on other sites More sharing options...
Michigander Posted December 23, 2012 Share Posted December 23, 2012 DTX clearly taking the conservative approach comparatively, which I don't blame them for. In reality there is a wide range of possibilities. Too bad they don't reflect that more clearly. GFS is moving the storm west as well. Link to comment Share on other sites More sharing options...

wisconsinwx Posted December 23, 2012 Share Posted December 23, 2012 Yeah it sucks being stuck in the middle. I am just hoping for a couple inches of lake effect as a consolation prize, to an otherwise lame December. Yeah, I would be satisfied if I see an inch or so through Wednesday, however now the event later this week into the weekend looks to be trending SE as well. Hopefully that changes.

ILSNOW Posted December 23, 2012 Share Posted December 23, 2012 Chicago with multiple chances next few days AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 332 PM CST SUN DEC 23 2012 .DISCUSSION... 332 PM CST ACTIVE WEATHER PATTERN NEXT 4 DAYS APPEARS TO BE GETTING MORE ACTIVE WITH CHANCES FOR MULTIPLE SNOW EVENTS IN THE OFFING OF VARYING INTENSITIES FROM A FEW TENTHS ACCUMULATION UP TO POTENTIALLY 6 INCHES OR MORE WITH MODELS TRENDING FARTHER NORTH AND WEST WITH WEDNESDAYS LOW. MID-HI CLOUDS ALREADY SPILLING RAPIDLY EAST IN ADVANCE OF APPROACHING INITIAL SHORTWAVE TROUGH OVER THE WESTERN DAKOTAS LATE THIS AFTERNOON. THESE CLOUDS OVERSPREADING THE TOP OF THE SC DECK THAT HAD ADVECTED SOUTH ACROSS THE FORECAST AREA EARLIER TODAY. AS MOISTURE INCREASES INTO THE OVERNIGHT HOURS AND LOW LEVEL BAROCLINIC ZONE TIGHTENS... CONCERNED WE COULD SEE PATCHY FREEZING DRIZZLE BREAK OUT... AND WITH TEMPS BELOW FREEZING... RESULT COULD BE A THIN GLAZE ON UNTREATED OUTDOOR SURFACES. AT THIS POINT NOT EXPECTING A WIDESPREAD ENOUGH OF AN EVENT TO WARRANT AN ADVISORY... BUT LATER SHIFTS WILL NEED TOO MONITOR CLOSELY AND INTERESTED PARTIES SHOULD CLOSELY MONITOR LATER FORESTS. AS ENTIRE COLUMN MOISTENS THROUGH 700-725 MB INTO THE DAY MONDAY... ALBEIT ONLY FOR A BRIEF TIME... AND STRONG ASCENT DEVELOPS IN ADVANCE OF UPPER LEVEL SHORTWAVE TROUGH PER DIFFERENTIAL PVA... EXPECT BRIEF DURATION LIGHT SNOW EVENT FOR MUCH OF THE FORECAST AREA NORTH OF I-80 AND MORE SO NORTH OF I-88 WHICH COULD RESULT IN A LIGHT ACCUMULATION. GIVEN LOW PWAT/H850 DEW POINTS AND ONLY BRIEF MOISTENING PER FORECAST SOUNDINGS... EXPECT ANY ACCUMULATING SNOW TO LAST ONLY AN HOUR OR TWO OR THREE... WITH ONLY UP TO A HALF INCH OF SNOW... IF THAT... WITH THE BETTER CHANCES OF THIS HAPPENING FROM I-88 AND EISENHOWER EXPWY NORTH TO THE WI BORDER. BOUNDARY LAYER THROUGH 800 MB FLOW THEN TURNS NORTHERLY BEHIND THE SHORTWAVE MONDAY NIGHT INTO TUES/XMAS DAY. RESULTING FETCH DOWN THE LENGTH OF THE LAKE COMBINED WITH 850 TEMPS AT -9/-10 DEG C WITH LAKE SFC WATER TEMP STILL GENERALLY IN THE MID-UPPER 40S PER LATEST SATELLITE ESTIMATES... PRODUCING A DELTA T OF 16-17 DEG C... YIELDS LAKE INDUCED INSTABILITY MORE THAN SUFFICIENT TO GENERATE LAKE EFFECT SNOW... AND GIVEN THE ORIENTATION OF THE WIND TO THE LAKE... COULD BE MORE OF A ENHANCED SINGLE BAND WHICH COULD BE A DECENT SNOW PRODUCER FOR AREAS FROM CHICAGO DOWNTOWN THROUGH THE NORTH SHORE. ANY SNOW ACCUMULATIONS WILL DEPEND ON THE DEGREE TO WHICH CONVERGENCE ALONG EITHER SIDE OF A BAND IS ABLE TO HELP RAISE THE CAPPING INVERSION... CURRENTLY DEPICTED BY THE MODEL FORECAST SOUNDS TO BE ABOUT 5000-6000 FT. THE DURATION IN WHICH ANY BAND MAY PERSIST WILL ALSO PLAY A ROLE IN SNOW ACCUMULATION... WITH CURRENT MODEL TRENDS HINTING AT A BANDED STRUCTURE SLOWLY PROPAGATING WESTWARD DURING THE COURSE OF THE DAY TUESDAY. IF THESE EVENTS WERE NOT INTERESTING ENOUGH... GFS/NAM/GEM LATEST TRENDS TO BRING DEVELOPING SFC LOW PROGGED TO MOVE THROUGH THE OHIO VALLEY ON WEDNESDAY FARTHER TO THE NORTH AND WEST WILL BRING YET A THIRD SHOT AT POTENTIALLY ACCUMULATING SNOW IN AS MANY DAYS TO MUCH OF CHICAGOLAND... WITH LESSOR CHANGES AS FAR WEST AS ROCKFORD. THIS EVENT APPEARS SOMEWHAT OMINOUS FOR AREAS DOWNWIND OF LAKE MICHIGAN IN ILLINOIS WITH THE AFOREMENTIONED LAKE INDUCED INSTABILITY REMAINING PRESENT OVER THE LAKE INTO WEDNESDAY WHICH BECOMES SUPERIMPOSED BY SYNOPTIC SCALE ASCENT ASSOCIATED WITH THE ISENTROPIC LIFT IN THE WARM AIR ADVECTION SECTOR OF THE LOW... WHICH WILL SERVE TO RAISE THE CAPPING INVERSION AND HELP GENERATE A MORE PROLIFIC PERIOD OF LAKE ENHANCED SNOW INTO THE CHICAGO/NORTH SHORE NORTHWARD INTO LAKE COUNTY, ILLINOIS. MEANWHILE... AS THE SURFACE LOW MOVES UP THE OHIO VALLEY... MODELS ARE HINTING AT A LOW REFORMING EAST OF THE APPALACHIANS OVER THE MID ATLANTIC WEDNESDAY NIGHT INTO THURSDAY... BUT NOT BEFORE LAYING DOWN A SWATH OF 6 INCH PLUS SNOW ACROSS A PORTION OF SOUTHERN IL INTO CENTRAL IN. GIVEN CURRENT MODEL TRACKS... FAR SE COUNTIES OF THE FORECAST AREA FROM PAXTON TO WATSEKA TO RENSSELAER WOULD SEE ACCUMULATING SNOW AS WELL. ALL INTERESTS CERTAINLY SHOULD BE ADVISED TO MONITOR LATER FORECASTS. FOLLOWING A PERIOD OF NW FLOW LAKE EFFECT SNOW INTO INDIANA THURSDAY... RIDGING ACROSS THE REST OF THE AREA WILL BRING QUIET WEATHER THURS-FRI BEFORE ANOTHER UPPER LEVEL SYSTEMS BRINGS ANOTHER CHANCE OF SNOW SAT INTO SUN. WILL ISSUE SPS TO HIGHLIGHT/DISCUSS SNOW POTENTIAL NEXT FEW DAYS. ED F Link to comment Share on other sites More sharing options...

Even with a stronger storm than the NAM it's cold sector precip towards back towards IL/IN/OH is pretty lame Truth is probably somewhere in the middle.

Given how much moisture that's available on the GFS/NAM I'd agree that a blend is probably the best bet. Link to comment Share on other sites More sharing options...

csnavywx Posted December 23, 2012 Share Posted December 23, 2012 18Z GFS somewhat further NW and stronger at first glance. Lined up closer to the NAM.

Rainman Posted December 23, 2012 Share Posted December 23, 2012 Not to go off topic or anything, but am I the only one who laughed when Paducah mentioned 6 inches of snow and impossible travel in the same sentence? Are the people there smurfs or something? Pretty sure you can drive a smart car through 6" of snow as long as it's not icy underneath or drifting to 2 feet. What's with the hyperbole? Link to comment Share on other sites More sharing options...
csnavywx Posted December 23, 2012 Share Posted December 23, 2012 6" events are fairly rare down there. Snow removal equipment is more sparse and folks aren't used to driving in it. Add in the wind/drifting and that's a very challenging driving environment, especially when snow rates are high. All of that makes a big difference. It might not be a big deal to a Minnesotan but it certainly is to a Kentuckian. Link to comment Share on other sites More sharing options...
hm8 Posted December 23, 2012 Share Posted December 23, 2012 DTX conservative, but makes some good points 2. SPLITTING OF THE LARGE UPPER CIRCULATION OFF THE COAST OF THE PAC NW IS NOW UNDERWAY IN RESPONSE TO AGGRESSIVE SHORTWAVE RIDGING BUILDING IN ADVANCE OF ANOTHER STRONG PACIFIC WAVE THAT WAS CENTERED NEAR 165W THIS AFTERNOON. THIS RIDGE AMPLIFICATION AND SUBSEQUENT SPLIT OF THE UPPER LOW WILL BE DIRECTLY RESPONSIBLE FOR THE DEVELOPMENT AND PROPAGATION OF A STRONG JET CORE THAT WILL DIG AGGRESSIVELY TOWARD THE GULF COAST. THE SUBSEQUENT RESPONSE WILL BE FOUND AT A CORRESPONDINGLY LOW LATITUDE, ALLOWING A LOW OF GULF COAST ORIGIN TO RAPIDLY DEEPEN DURING THE DAY ON TUESDAY, ENTRAINING A GREAT DEAL OF MOISTURE AS IT DOES SO. SYSTEM RELATIVE PROGS SUGGEST THE DEVELOPMENT OF A HEALTHY WARM CONVEYOR CHARACTERIZED BY STRONG THETA-E ADVECTION AND MODERATE TO LOCALLY STRONG SYSTEM RELATIVE ISENTROPIC ASCENT WRAPPING INTO THE COLD SECTOR BELOW 700MB. WHEN CONSIDERED ALONG WITH STRONG SYNOPTIC SCALE FORCING AND A FULLY MATURE DEFORMATION ZONE, THERE IS REASONABLY HIGH CONFIDENCE THAT THIS SYSTEM WILL BRING A SWATH OF 6+" TO A PORTION OF THE NORTHEAST UNITED STATES WED INTO WEDNESDAY NIGHT. AS EXPECTED, THE 12Z GEM NOW DEPICTS A MORE WESTWARD TRACK AND FALLS IN LINE WITH THE NAM/GFS/LOCAL WRF GLOBAL IN ITS DEPICTION OF A SURFACE LOW TRACK ALONG THE WEST SIDE OF THE APPALACHIAN MOUNTAINS, REACHING AT LEAST CINCINNATI BEFORE THE NECESSARY TRANSITION TO THE EAST SIDE OF THE MOUNTAINS GETS UNDERWAY. LOCALLY, THIS MEANS A STORM-TRACK-SENSITIVE POTENTIAL FOR PART OF THE CWA TO FALL WITHIN THE FAVORED SWATH FOR 6+". AS NOTED YESTERDAY, WHEN AND WHERE THAT ACTUALLY OCCURS WILL DEPEND ON MULTIPLE FACTORS, NOT THE LEAST OF WHICH WILL BE THE NORTHWARD PROGRESS OF THE LOW-LEVEL CIRCULATION BEFORE THE TRANSITION ACROSS THE MOUNTAINS BEGINS. IT MAY ALSO BE WORTH NOTING THAT THE RATHER LARGE SWATH OF COLD SECTOR SNOWFALL DEPICTED BY THE NAM/GFS ARE FAIRLY TYPICAL OF THESE MODELS WHICH LACK PARAMETRIZATION FOR ELEVATED CONVECTION. A MORE REALISTIC EXPECTATION WOULD BE FOR A MORE TRUNCATED NORTHWESTERN EDGE, WHICH ARGUES FOR A MORE CONSERVATIVE APPROACH TO THE FORECAST FOR NW PORTIONS OF THE CWA AT THIS TIME. A COUPLE OF ADDITIONAL POINTS WORTH JUST A MENTION AT THIS POINT ARE THE POTENTIAL FOR WARM SECTOR CONVECTION TO INTERFERE WITH MOISTURE TRANSPORT AND FOR THE MODELED VERSION OF WARM SECTOR CONVECTION TO FORCE AN ERRONEOUS EASTWARD TENDENCY IN THE NWP ON ACCOUNT OF CONVECTIVE FEEDBACK. REGARDING THE LATTER, A QUICK LOOK THROUGH THE LOWER TROPOSPHERIC PV PANELS REVEALS NOTHING OF NOTE AND SUGGESTS THAT NONE OF THE 12Z GUIDANCE ARE SUFFERING FROM SUCH CONVECTIVE FEEDBACK/EASTWARD TRACK BIAS AT THIS TIME. THE PRIMARY CHANGE TO THE FORECAST IS THEREFORE NOTHING MORE THAN A FINE TUNING OF POPS AND SNOWFALL TO REFLECT THE LATEST CONSENSUS AND PROVIDE ADDITIONAL SUPPORT TO THE INHERITED FORECAST WHICH FAVORS A STORM TRACK WEST OF THE APPALACHIANS. AT THIS TIME RANGE, WILL NOT GET CUTE WITH STORM TOTALS AND WILL MAINTAIN THE AFOREMENTIONED CONSERVATIVE APPROACH ALONG THE NW EXTENT OF THE PROGGED SNOW SHIELD. THE LATE-ARRIVING 12Z ECMWF IS IN STRONG AGREEMENT WITH THE REST OF THE 12Z GUIDANCE IN THAT THE SURFACE LOW REACHES SOUTHERN OHIO BEFORE ANY TRANSFER REALLY TAKES PLACE, AND ITS SURFACE FIELDS MOST STRONGLY REFLECT CURRENT EXPECTATIONS GIVEN THE PRECEDING DISCUSSION. THE OFFICIAL FORECAST IS CURRENTLY A CONSERVATIVE, BUT STILL REALISTIC, SWATH OF 3-5" ACROSS THE SOUTHEAST 2/3 OF THE AREA BETWEEN WED AND THURS MORNINGS.

kerbs Posted December 23, 2012 Share Posted December 23, 2012 ILN LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/ FOCUS IS ON THE WINTER STORM WHICH WILL AFFECT THE REGION AT MID WEEK. VIGOROUS MID LEVEL S/W TO LIFT FROM THE SRN PLAINS INTO THE LOWER OH VLY TUESDAY NIGHT AND ACRS THE REGION WEDNESDAY. NUMERICAL MODEL SOLNS CONTINUE TO SHOW SPREAD REGARDING THE EXACT TRACK OF THE ASSOCIATED SFC WAVE WHICH LIFTS NE THRU THE REGION ON WEDNESDAY. IN GENERAL THE GFS DETERMINISTIC SOLNS HAVE BEEN THE FURTHEST WEST AND THEREFORE BRING MORE WARM AIR INTO ILN/S FA. THE ECMWF SOLN HAS BEEN MORE CONSISTENT WITH THE LATEST 12Z DETERMINISTIC RUN TRENDING A LITTLE WEST AND THEREFORE ALLOWING A LTL MORE INTRUSION OF WARM AIR. GFS ENSEMBLE MEAN SOLN IS PLACED A LTL EAST OF ITS DETERMINISTIC RUN. HAVE TRENDED THE LATEST FCST TOWARD THE A SLIGHTLY MODIFIED (WARMER) SOLN THAN 12Z ECMWF RUN GIVEN TRENDS AND CONSISTENCY. HAVE SPREAD LKLY POPS IN FROM THE SOUTH TUESDAY NIGHT AND THEN BUMPED UP POPS TO CATEGORICAL EARLY WEDNESDAY. USING AT TOP DOWN TECHNIQUE APPLIED TO MODIFIED ECMWF SOLN HAVE FAR WEST CENTRAL OHIO (NORTHWEST OF DAYTON) STAYING ALL SNOW BUT HAVE A MIX SPREADING INTO THE REMAINDER OF ILN/S FA AND RAIN SE OF I-71 DURING THE DAY ON WED. AS COLDER AIR WRAPS INTO THE SYSTEM...HAVE ALL PRECIP CHANGE BACK TO SNOW WEDNESDAY NIGHT. THIS SYSTEM HAS THE POTENTIAL TO PRODUCE 6 INCHES OR MORE OF SNOW AND SIGNIFICANT ICE. AT THIS TIME IT LOOKS LIKE A STORM TOTAL 4 TO 6 INCH SNOW BAND IS PSBL FROM EAST CENTRAL INDIANA THRU FAR W CNTRL OHIO. THERE WILL LKLY BE A SHARP CUT OFF TO THE SE WITH 1 TO 2 INCHES ALONG AND JUST WEST OF I-71 AND LESS THAN AN INCH SE OF I-71. GIVEN THE HIGH DEGREE OF UNCERTAINTY REGARDING THE EXACT TRACK... WILL CONTINUE TO HIGHLIGHT THIS THREAT IN THE HWO PRODUCT. AS THIS WINTER STORM LIFTS NE WILL TAPER OFF SNOW EARLY ON THURSDAY. UPPER LEVEL RIDGING AND SFC RIDGING TO BUILD IN PROVIDING DRY WX CONDITIONS LATER THURSDAY AND FRIDAY. MODEL SOLN DIFFERENCES REGARDING THE WEATHER SYSTEM NEXT WEEKEND. PREV GFS WAS KEEPING PCPN TO OUR SOUTH BUT LATEST RUN BRINGS IN PRECIP BUT IS WEAKER AND ALLOWS FOR LESS WARM AIR. ECMWF SOLNS HAVE BEEN STRONGER AND ALLOW FOR MORE INITIAL WARM AIR INTRUSION. HAVE SPREAD CHC POPS IN FRIDAY NIGHT AND THEN CONT HIGH CHC POPS ON SATURDAY. HAVE ALLOWED FOR A MIX OF RAIN AND SNOW OVER THE SE HALF AND KEPT ALL SNOW NW. SOME LINGERING SNOW SHOWERS WILL BE PSBL ON SUNDAY WITH THE BEST CHC ACRS THE NORTH. Link to comment Share on other sites More sharing options...
