jojo762 Posted February 21, 2013 Share Posted February 21, 2013 Dryslot. Snow will fill in later once the deformation band takes shape as the upper low ejects. Figured... Wasn't entirely sure if another snow band would form... I figured the upper low had already ejected over the rockies, haven't really paid too much attention to the satellite lately. I haven't researched winter weather too much, so i'm kind of a noob at winter weather stuff... Link to comment Share on other sites More sharing options...
Bryan Wood Posted February 21, 2013 Share Posted February 21, 2013 Reports of Thunder FZRA in northern Arkansas. There are going to be some really quick ice accumulations there. Think we'll see some 3's on the Sperry-Piltz Ice Damage Index there. Link to comment Share on other sites More sharing options...
Srain Posted February 21, 2013 Share Posted February 21, 2013 MESOSCALE DISCUSSION 0189 NWS STORM PREDICTION CENTER NORMAN OK 1119 AM CST THU FEB 21 2013 AREAS AFFECTED...NERN KS...FAR SERN NEB...CNTRL/NRN MO CONCERNING...HEAVY SNOW VALID 211719Z - 212115Z SUMMARY...HEAVY SNOW WITH SNOWFALL RATES IN EXCESS OF 1 INCH PER HOUR WILL TRANSITION NEWD ACROSS NRN MO WHILE BEGINNING TO END ACROSS NERN KS AND NWRN MO. A TRANSITION ZONE WITH A MIX OF FZRA/PL/SN WILL LIKELY DEVELOP ACROSS W-CNTRL MO AS WARM AIR ALOFT CONTINUES MOVING NEWD INTO THE AREA. DISCUSSION...VERY HEAVY SNOWFALL HAS FALLEN ACROSS MUCH OF NERN MO WITH SNOWFALL TOTALS FROM 7 TO 11 INCHES IN AND AROUND THE KANSAS CITY METRO. RECENT RADAR IMAGERY HAS SHOWN A DRYING TREND ACROSS ERN KS AS THE MID-LEVEL DRY SLOT MOVES INTO THE REGION. TRACKING THE NRN DEMARCATION BASED ON RADAR IMAGERY PLACES IT IN THE KANSAS CITY METRO AROUND 1730Z. AS A RESULT...THE HEAVY SNOWFALL ACROSS NWRN MO IS EXPECTED TO END WITH A TRANSITION TO MORE LIGHT SNOW/FREEZING DRIZZLE AS THE MID-LEVELS DRY. FARTHER N AND E...HEAVY SNOWFALL IS EXPECTED TO BEGIN AS STRONG WAA INFLUENCES THE REGION. ORIENTATION OF THE WAA APPEARS TO FAVOR HEAVY SNOWFALL...WITH SNOWFALL RATES IN EXCESS OF 1 INCH PER HOUR...ACROSS N-CNTRL AND NERN MO WHILE SNOWFALL RATES REMAIN LOWER ACROSS NWRN MO AND FAR SERN NEB. CONTINUED WARMING ALOFT WITH SURFACE TEMPERATURES REMAINING BELOW FREEZING WILL LIKELY LEAD TO A TRANSITION FROM SNOW TO MORE MIXED PRECIPITATION ACROSS W-CNTRL MO. LIGHTNING HAS BEEN NOTED WITHIN THE ACTIVITY ACROSS CNTRL MO AND RESULTANT PRECIPITATION RATES IN EXCESS OF 0.10 INCH/HR ARE POSSIBLE. PRIMARY PRECIPITATION TYPE WILL REMAIN AS SNOW BUT AN INCREASING FREQUENCY OF SLEET APPEARS POSSIBLE. SOME FREEZING RAIN CANNOT BE RULED OUT BUT THE DEPTH OF THE COLD AIR BENEATH THE WARM NOSE ALOFT WILL LIMIT ITS FREQUENCY. ..MOSIER.. 02/21/2013 ATTN...WFO...LSX...DVN...SGF...EAX...OAX...TOP...

fishnut Posted February 21, 2013 Share Posted February 21, 2013 Snow has subsided a bit here in Emporia... I expected Moderate/Heavy snow for most of the morning hours through about 3PM... What happened? Seven inches in two hours this morning in Topeka. We're temporarily in the dry air now. Link to comment Share on other sites More sharing options...

jcwxguy Posted February 21, 2013 Share Posted February 21, 2013 Storm total here in Mcpherson 13.80" with 1.50" of liquid equivulant Link to comment Share on other sites More sharing options...
Siberian Express Posted February 22, 2013 Share Posted February 22, 2013 Snowing, at 6:30am, measured 4.5". Nice powder coating over the existing pack, pretty high ratio 15:1 or so, I'd guess. One good thing, there is no real wind with this system up here. Link to comment Share on other sites More sharing options...

prinsburg_wx Posted February 22, 2013 Share Posted February 22, 2013 Nice, where are you at again in MN? I think Siberian Express lives by Red Wing...I had about 3" here, still snowing lightly. Link to comment Share on other sites More sharing options...
Crazieman Posted February 22, 2013 Share Posted February 22, 2013 14.2 inches, making it the 2nd largest in Wichita history. I don't know the moisture content offhand. Link to comment Share on other sites More sharing options...
Chad A Posted February 22, 2013 Share Posted February 22, 2013 Just over 5 inches in Lincoln, more to our northeast towards Omaha as a short lived TROWAL seemed to set up around Omaha - boosting their reports to 8 and over. The dry slot killed us. Actually a Double whammy of dry did us in. That cold dome of high pressure over IA east of the low - dewpoints barely above 0. Advect that at the surface into the cyclone on easterly winds... no matter what the mid level waves threw at us early - no snowfall accumulations as it was drying out before hitting the surface. I think the models had a good handle on that... That continued until we got enough forcing late (same forcing causing thundersnow I believe, but angled northward) morning to overcome the dry low levels... then after that went thorugh, our mid levels dried out... heck even though it was still snowing. We were showing mod snow with 1/2 and sometimes 1/4 mile visibilities but the dendrites were so horrible we weren't accumulating as much as you would think just looking at observations and radar. I think that is attributed to not deep enough moisture... they looked like tiny needles...so fine it looked like fog. Maybe 2 or 3 inches of that by 3 pm. Wasn't until the 500 mb low got closer did we start to see better accumulating snow about 5 pm. Anyway, it covered the ground white, so I'm happy.

Siberian Express Posted February 23, 2013 Share Posted February 23, 2013 I think Siberian Express lives by Red Wing...I had about 3" here, still snowing lightly. Yep, a few miles SE of Red Wing. Ended with 6" and it warmed up quick and really compacted. Link to comment Share on other sites More sharing options...
