Norman is a difference of what, 30 miles? And most likely to see an EF2-3? How do you figure that out? Link to comment Share on other sites More sharing options...

So you can predict not only tornado damage ratings in advance but their location to within 20 miles? Alrighty. Link to comment Share on other sites More sharing options...

AgeeWx Posted April 17, 2013 Share Posted April 17, 2013 New MD for the Tornado Watch previously issued, saying pretty much what the 18Z SGF sounding indicates. 291 ACUS11 KWNS 172038 SWOMCD SPC MCD 172038 ILZ000-MOZ000-ARZ000-OKZ000-KSZ000-172215- MESOSCALE DISCUSSION 0497 NWS STORM PREDICTION CENTER NORMAN OK 0338 PM CDT WED APR 17 2013 AREAS AFFECTED...WRN AND CENTRAL MO/EXTREME ERN KS/W CENTRAL IL CONCERNING...TORNADO WATCH 114...

SUMMARY...ENVIRONMENT REMAINS CONDUCIVE FOR SEVERE TSTM DEVELOPMENT ACROSS WW 114 THROUGH THE LATE AFTERNOON...WITH ALL FACETS OF SEVERE WEATHER REMAINING A THREAT. DISCUSSION...MID AFTERNOON SURFACE ANALYSIS COMBINED WITH TRENDS IN REGIONAL RADAR IMAGERY INDICATED AN OUTFLOW BOUNDARY ATTENDANT TO TSTMS LOCATED E OF THE KANSAS CITY METRO AREA MAY BE TENDING TO TEMPER THE NWD MOVEMENT OF THE WARM FRONT INTO NWRN MO. AT 2015Z...THIS BOUNDARY EXTENDED FROM EAST CENTRAL KS THROUGH BATES COUNTY MO TO PETTIS COUNTY MO. THIS FRONT THEN EXTENDED GENERALLY EWD ALONG AND N OF THE I-70 CORRIDOR AS A WARM FRONT. THE WARM SECTOR HAS BECOME MODERATELY TO VERY STRONGLY UNSTABLE WHILE EFFECTIVE BULK SHEAR HAS INCREASED TO 40-50 KT. THUS...SUPERCELLS REMAIN LIKELY WITH STEEP MIDLEVEL LAPSE RATES ALSO ENHANCING THE POTENTIAL FOR VERY LARGE HAIL. THE DISCRETE STORM LOCATED IN ERN ST CLAIR TO SWRN BENTON COUNTIES MO APPEARS TO BE LOCATED WITHIN A ZONE OF LOW LEVEL CONFLUENCE THAT EXTENDED FROM SWRN MO TO 15 E KSZL.

wxmeddler Posted April 17, 2013 Share Posted April 17, 2013 I can't tell what's going on with the Frederick cell.. It's too close to the radar! The velocity has greens (winds towards the radar) 300° around it. Talk about convergence. Link to comment Share on other sites More sharing options...
