JoMo Posted February 28, 2013 Share Posted February 28, 2013 18z GFS shows a monster storm for southern MO and Northern ARK around 300 hours. I can't help myself from looking. I'm addicted... yeah, around the 10th or so. That's been showing up from time to time, but I'd like to see a little more consistency before I consider it a threat.

BryanB Posted February 28, 2013 Share Posted February 28, 2013 Well after not receiving any snowfall to speak of in Kansas City last winter…and a slow start this year we sure have made up for it in the last 7 days. On Feb 21-22 winter storm we received 11 inches of snowfall here in western Wyandotte County Kansas and then on Feb 25-27 we received another whopping 12.5 inches of snowfall for a grand total of 23.5 inches of snowfall. I believe according to the folks at the weather forecast office that this makes it our snowiest 7-day period on record and our second snowiest February on record. This should surely help with the drought that we have been dealing with since April of last year. Also, as rare as thundersnow is we received it with both winter storms across the entire Kansas City area, unfortunately this most recent storm was a very wet heavy snowfall and brought down numerous trees and power lines and left approximately 120K in the dark.

NwWhiteOut Posted March 2, 2013 Share Posted March 2, 2013 yeah, flurries all day, pretty nice. Its nice to see for once isnt I got about 3/4 of an inch though that mainly just accumulated on top of what snow I had on the ground where the temps were below freezing still. What do you think jomo, you think thats it for the season now? I've had my share and fun it was nice to actually see something Link to comment Share on other sites More sharing options...

What do you think jomo, you think thats it for the season now? I've had my share and fun it was nice to actually see something I think that might be it, but you never know. One big storm system tracking south with enough cold air around and we end up with a lot of snow again. It doesn't look like that will happen at this time though. I had thundersnow, large flakes, and a decent accumulation so overall, I'd give this winter a D- for here. An F for NW Arkansas. Sorry guys Link to comment Share on other sites More sharing options...
MoWeatherguy Posted March 2, 2013 Share Posted March 2, 2013 The system around the 10th still has my interest, albeit not as much as a few days ago. All it needs is a little more cold air pulled in or manufactured and it could be a nice winter storm for somebody close by. Link to comment Share on other sites More sharing options...
The Waterboy Posted March 2, 2013 Share Posted March 2, 2013 Is there a grade lower than F? If this winter were a movie it would be Winter's Bone. I did just go to the gas station and its snowing pretty big flakes. Almost a dusting on the road. It's sad that's about the extent of this winter.

NwWhiteOut Posted March 2, 2013 Share Posted March 2, 2013 Its been pretty lousy but i really cant complain as Im doing better this week then I did all last winter season. Im close to probly 9.5-10" now for this season. Last year I think I had a total of like 3" lol. I usually keep track with notepad in windows cause I got short term memory and cant remember squat lol. And sorry waterboy thats gotta suck! You guys just cant catch a break down there, I guess thats probly what I have to look forward to once I move down that way huh lol On a side note springfields late night disco mentioning something about tuesday afternoon through evening northwest of i-44 again, rain over to snow I believe it said Link to comment Share on other sites More sharing options...

Wx 24/7 Posted March 10, 2013 Share Posted March 10, 2013 I love the rolling thunder with a gentle rain as I sleep. This is great weather! Not as good as a winter snowstorm, but I will take it. Link to comment Share on other sites More sharing options...
JoMo Posted March 10, 2013 Share Posted March 10, 2013 Yeah, I can handle thunder much better now. Joplin Globe had an article today that said we would have a 'near normal' severe weather season this year. I think our first shot at severe weather will probably be sometime late March. I remain a little concerned due to the ongoing drought to the west of us and the recent rains we have had. Unless OK and KS get a lot of rain soon, that may allow the dryline to push farther east that usual which usually means we get more severe weather. My GREarth subscription runs out in April. I think I'll probably just get the $10 Allisonhouse sub. for GRLevel 3 since anything I looked at in GREarth has an AH placefile probably. Link to comment Share on other sites More sharing options...

JoMo Posted March 18, 2013 Share Posted March 18, 2013 Doug Cramer is pretty gung-ho about this storm. He's been pretty 'meh' most of this winter. SGF AFD this afternoon. WINTER STORM THURSDAY - FRIDAY:WE HAVE A COUPLE OF DIFFERENT AIRMASSES THAT WILL BE COLLIDING WITHONE ANOTHER OVER EASTERN KANSAS AND SOUTHERN/CENTRAL MISSOURI ONTHURSDAY.AN USUALLY COLD AIRMASS WAS POSITIONED THIS AFTERNOON ACROSS THEDAKOTAS AND SOUTHERN CANADA. MEANWHILE...GULF BUOYS WERE MEASURINGDEW POINTS IN THE 60S AND LOWER 70S ACROSS MUCH OF THIS MOISTURESOURCE REGION.BOTH THE CANADIAN AIR...AND THE GULF AIR...WITH TRACK TOWARDS THEOZARKS THROUGH THE WEEK...WITH THE RESULT BEING A LATE WINTER SNOWSTORM. I FULLY EXPECT A SWATH OF HEAVY SNOW WITH THISINTERACTION...AS THIS WINTER STORM WILL HAVE MORE MOISTURE AVAILABLETO IT...THAN ANY OTHER WINTER STORM WE`VE HAD ALL YEAR. TREMENDOUSMOISTURE.ALSO...WE ARE BECOMING CONFIDENT WITH PRECIPITATION TYPE BEINGMOSTLY SNOW...DUE TO THE PRESENCE OF THE NORTHERN PLAINS AIRMASS.WE HAD THOROUGH DISCUSSIONS WITH WPC MODEL DIAGNOSTICS THIS MORNINGREGARDING MODEL PERFORMANCE WITH THIS SYSTEM. THEY HIGHLY SUGGESTEDLEANING THE THURSDAY FORECAST TOWARD THE ECMWF...SINCE IT`S BEEN THEMOST CONSISTENT FROM RUN TO RUN OVER THE LAST FEW DAYS.THE ECMWF HAS ALSO BEEN THE COLDEST...WHICH MAKES SENSE GIVEN THEAIRMASS TO THE NORTH. THE CANADIAN MODEL`S MASS FIELDS LOOK VERYSIMILAR TO THE ECMWF...WHILE THE GFS CONTINUES TO TREND TOWARDTHESE TWO SOLUTIONS.WE THINK LOCATIONS ALONG AND NORTH OF A LINE FROM FORT SCOTT KANSASTO FAIR GROVE...TO EMINENCE MISSOURI WILL RECEIVE THE GREATESTCHANCES FOR A SWATH OF HEAVY SNOW 6 INCHES OR MORE.LESSER AMOUNTS ARE EXPECTED TOWARD THE ARKANSAS AND OKLAHOMABORDERS...SINCE THE RAIN-SNOW LINE COULD BE POSITIONED ACROSSSOUTHERN MISSOURI OR NORTHERN ARKANSAS.A BRIEF PAUSE IN THE SNOW IS EXPECTED BY FRIDAY AFTERNOON THROUGHSATURDAY MORNING...BEFORE POSSIBLY PICKING UP AGAIN SATURDAYAFTERNOON INTO SUNDAY. SOME ADDITIONAL MINOR ACCUMULATIONS AREPOSSIBLE SATURDAY AFTERNOON INTO SUNDAY...BUT WE`LL GET MOREDETAILED WITH AMOUNTS IN COMING FORECASTS.CRAMER Tulsa not so much but they mention the weekend system: A SURFACE LOW WILL DROP SOUTHEASTWARD THROUGH THE PANHANDLESTHURSDAY AND INTO WESTERN NORTH TEXAS BEFORE SWINGING EASTWARDSOUTH OF THE RED RIVER THURSDAY NIGHT. INCREASING CLOUDS ANDRAIN IN RESPONSE TO THIS WILL KEEP TEMPERATURES WELL BELOW NORMALACROSS MUCH OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS THURSDAY.PRECIPITATION WILL CONTINUE INTO THURSDAY NIGHT AND PARTS OFFRIDAY...WITH SOME THREAT OF A CHANGEOVER TO FREEZINGRAIN...SLEET...OR SNOW FOR AREAS NEAR THE KANSAS AND MISSOURIBORDERS. THIS CHANGEOVER IS NOT COMPLETELY CERTAIN THIS FARSOUTH...THOUGH...WITH THERMODYNAMIC PARAMETERS CONTINUING TO LOOKMARGINAL. THE HIGHEST WINTRY PRECIPITATION ACCUMULATIONS SHOULDREMAIN NORTH OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.OF MORE CONCERN ON THE WINTRY SIDE OF THINGS IS THE SYSTEM THATWILL DROP THROUGH THE AREA THIS NEXT WEEKEND. THE MEDIUM RANGEMODEL SUITE ARE ALL IN AGREEMENT THAT A STRONGER SYSTEM WILL MOVETHROUGH THE AREA...WITH COLD AIR ALREADY WELL ESTABLISHED. BOTHTHE GFS AND ECMWF ARE STRONGLY HINTING AT SNOW ACCUMULATIONS FOR AGOOD PART OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS...WITHSATURDAY NIGHT BEING THE FAVORED TIMING. THE BIG QUESTION AT THISPOINT HAS LESS TO DO WITH THERMODYNAMICS THAN IT DOES HOW MUCHPRECIPITATION WILL FALL. HAVE GONE RATHER CONSERVATIVE WITHFORECAST AMOUNTS DUE TO THIS QUESTION...BUT THE POTENTIAL FORTHESE TO INCREASE IN FUTURE FORECASTS DEFINITELY EXISTS.
