andyhb Posted December 17, 2012 Share Posted December 17, 2012 As has been mentioned the next trough diving into the west should certainly bring some strong kinematics supporting potentially severe weather and a snow storm for the Front Range/Central and High Plains, with pseudo-Colorado Low development taking place to the leeside of the Rockies. Discussion for this system can fall here. Link to comment Share on other sites More sharing options...
baroclinic_instability Posted December 17, 2012 Share Posted December 17, 2012 First legit CO low of the season. Count me excited even if it is going to be mildly suppressed by the northern stream influence. Link to comment Share on other sites More sharing options...
Jim Marusak Posted December 17, 2012 Share Posted December 17, 2012 so far, latest models... by t+84, the current high snow axis on the top-side of the storm for the following models, roughly estimated for the obs-sites visually the NAM is the northern model and clocks areas from nw IA to sc-MN and ec-MN to northern WI and the UP. (SUX-SPW-MKT-MSP-FBL-RST-RGK-RCX-ASX-CMX-SAW) with the center just north of DVN the Euro is the southern-most models by a longshot and mainly affects nc- MO, eastern IA, and far southern WI (IRK-AWG-DVN-JVL-MKE) with the center near STL in the middle, the GFS and Canadian-Global models goes MCI-DSM-PDC-ISW-GRB (maybe MSN) with the center on the GFS near PIA and the Canadian center near COU (delayed, but similar path) gonna be interesting for sure.

In terms of IMBY (MN...I am leaving for MN for Christmas in a few hours), the northern edge is going to be frustratingly tight along the frontogenesis band...there will be a clear demarcation from no snow to a lot with this setup. This is going to be a tricky event for the Front Range. Eastern NE (in our zone is going to be the jackpot). Link to comment Share on other sites More sharing options...

This is going to be a tricky event for the Front Range. Eastern NE (in our zone is going to be the jackpot). Have a safe trip. Maybe you'll get 2 for the price of one this trip. Although it's STILL A WAYS OUT THERE...the models have shown a second system for almost a week now...on a similar track. This system may give portions of Texas...the southern plains...and gulf coast...a severe weather event on Christmas Day (+/- a day). Strong return flow and at least a day of "pre-conditionong" should allow the system to tap some good moisture. Backside of the system could give the central plains a good snow dump. Time will tell...and now that I said something...it'll prob vanish of the maps...lol. Link to comment Share on other sites More sharing options...
Chinook Posted December 17, 2012 Share Posted December 17, 2012 This storm is going to have a long zone of frontogenesis as it tracks through the Rockies. This is very good sign for cranking out the snow at the Colorado/Wyoming border for several hours, as well as the Wasatch in Utah. Check out these GFS plots of 850mb, 700mb, and surface temperatures tomorrow evening, with the strong temperature gradient. Looks like the GFS and NAM show over 0.5" of liquid for the northwest quarter of Colorado, leading to 5-10" of snow, and probably a jackpot at Steamboat Springs. I'm not so sure if we will have a big chance of over 5" east of the mountains. Nearly all of western Colorado is under a watch or warning for this. Steamboat area (10000ft.) * SNOW ACCUMULATION...TOTAL SNOW ACCUMULATIONS OF 18 TO 30 INCHES OF SNOW ARE EXPECTED BY LATE WEDNESDAY...WITH LOCALLY HIGHER AMOUNTS.

Srain Posted December 18, 2012 Share Posted December 18, 2012 SHORT RANGE FORECAST DISCUSSION NWS HYDROMETEOROLOGICAL PREDICTION CENTER COLLEGE PARK MD 358 AM EST TUE DEC 18 2012 VALID 12Z TUE DEC 18 2012 - 12Z THU DEC 20 2012 ...ACCUMULATING SNOWS ARE EXPECTED ACROSS INTERIOR NEW ENGLAND ON TUESDAY... ...ACTIVE WEATHER WILL CONTINUE FOR THE NORTHWESTERN CORNER OF THE COUNTRY AS ANOTHER PACIFIC SYSTEM APPROACHES THE COAST... ...FIRST WINTER STORM OF THE SEASON IS IN THE FORECAST FOR THE CENTRAL PLAINS... CONDITIONS SHOULD QUICKLY DRY OUT ACROSS THE SOUTHEAST AND MID-ATLANTIC STATES ON TUESDAY AS A COLD FRONT EXITS INTO THE ATLANTIC. HOWEVER...THE ANCHORING SURFACE LOW IS EXPECTED TO TRACK THROUGH PENNSYLVANIA AND DEEPEN OFF THE NORTHEAST COAST. AN ABUNDANCE OF ATLANTIC MOISTURE STREAMING INLAND WILL HELP PRODUCE AN ORGANIZED AREA OF MODERATE TO HEAVY PRECIPITATION ACROSS NEW ENGLAND ON TUESDAY...AND ENOUGH COLD AIR NOSING DOWN FROM CANADA SHOULD LEAD TO SIGNIFICANT SNOWFALL ACCUMULATIONS OVER INTERIOR NEW ENGLAND. BY EARLY WEDNESDAY...THE LOW WILL BE WELL OFF THE COAST AND ONLY A FEW LIGHT SHOWERS WILL LINGER OVER NEW ENGLAND FOR THE REMAINDER OF THE FORECAST PERIOD. THE NORTHWESTERN U.S. WILL NOT GET MUCH OF A BREAK FROM THE ACTIVE WEATHER PATTERN OVER THE NEXT FEW DAYS. SHOWER ACTIVITY WILL LIGHTEN UP A BIT ON TUESDAY...BUT THEN THE NEXT PACIFIC SYSTEM APPROACHING THE COAST WILL BEGIN IMPACTING THE REGION BY EARLY WEDNESDAY. STEADY RAINS ARE EXPECTED ALONG COASTAL AREAS...WHILE MODERATE TO HEAVY SNOWS WILL BE IN THE FORECAST FARTHER INLAND OVER THE WASHINGTON/OREGON CASCADES. FINALLY...ENERGY AMPLIFYING OVER THE SOUTHWEST WILL BRING WIDESPREAD SNOW SHOWERS ACROSS THE FOUR CORNER STATES ON TUESDAY. BY WEDNESDAY AFTERNOON...THE ENERGY WILL SWING OUT INTO PLAINS AND HELP DEVELOP A SURFACE LOW IN THE LEE OF THE COLORADO ROCKIES. THE STRENGTHENING SURFACE CYCLONE SHOULD QUICKLY TRACK NORTHEASTWARD TOWARDS THE MIDDLE MISSISSIPPI VALLEY...BRINGING STRONG WINDS AND A SWATH OF MODERATE SNOWS ACROSS THE CENTRAL PLAINS WEDNESDAY NIGHT INTO THURSDAY. IN ADDITION...INCREASING AMOUNTS OF GULF MOISTURE FUNNELING NORTHWARD AHEAD OF THE TRAILING COLD FRONT SHOULD HELP FIRE UP SHOWERS AND THUNDERSTORMS ACROSS THE LOWER MISSISSIPPI VALLEY BY THE END OF THE FORECAST PERIOD...SOME OF THESE DEVELOPING STORMS MAY BECOME STRONG OR EVEN SEVERE.

ksstormhunter Posted December 19, 2012 Share Posted December 19, 2012 SmartCast for 19 Dec/06Z to 20 Dec/06Z Here is what my model program is seeing at this hour for the next 24 hours: Omaha Region: Tracking snow beginning around 19/21Z, then rapidly increasing in intensity, with snowfall rates up to 1.7” from 00Z to 06Z. Blizzard like conditions beginning around 03Z. Winds will increase to 25 gusting 35 to 40MPH after 03Z. Snowfall accumulation through 20/06Z will be 11” Lincoln Region: Tracking snow starting around 23, then rapidly increasing in intensity, with snowfall rates up to 1.9” per hour and visibilities less than ½ mile. Blizzard conditions will be possible beginning 03Z as winds increase to 25 to 30MPH, gusting to 38 to 42MPH. Snowfall accumulation through 20/06 will be 11.5” Grand Island Region: Snow will begin around 17Z and be strongest from 22 to 04Z, with snowfall rates of 1.5” possible during this time frame. In addition, blizzard like conditions are possible from 00Z to 06Z with winds 25 to 30MPH, gusting to 38 to 42MPH. Snowfall accumulation through 20/06 will be 10.8” McCook Region: Snow will start around 17 and will peak from 20Z to 02, with snowfall rates of 1.3” during this time. Blizzard conditions will start from 21Z through 02Z, with wind gusting up to 38 to 41MPH during this time frame. Snowfall accumulation will be 9”. Across Kansas area from Goodland, KS to Wichita, KS looking at snowfall from 1 to 5”, winds will approach 45 to 60MPH across this region, causing blizzard like conditions, low visibilities, and dangerous wind chills.

DISCUSSION...DURING THE NEXT FEW HOURS...STRONG SFC CYCLOGENESIS WILL OCCUR OVER SWRN KS AND THE OK PANHANDLE AS STRONG DCVA LEADING AN APPROACHING PV MAX OVERTAKES A BROAD AREA OF LOW-LEVEL BAROCLINICITY. THE DEVELOPING SFC LOW WILL TRACK EWD NEAR OR JUST NORTH OF THE KS/OK BORDER THROUGH THIS EVENING...WHILE A VERY TIGHT SFC PRESSURE GRADIENT W/NW OF THE CENTER OF THE LOW SUPPORTS NNWLY/NLY WINDS OF 25 TO 40 MPH WITH GUSTS OF 45 TO 60 MPH.
