  1. I also found this one from the Reno radar back in 2008: http://apollo.lsc.vsc.edu/classes/remote/lecture_notes/radar/88d/KRGXDomeFailure.pdf Radome was smashed, then a few days later another high wind event finished the job.
  2. Thanks for posting this link. In the past I've looked for some of his papers, but had no luck finding them (at least online).
  3. One of the tornadoes in Indiana came from a storm that was embedded in moderate rain (Holton EF-3). It didn't have a long life (compared to the other supercells) but it was deadly. I was away from my computer for about an hour that afternoon (1:30-2:30 or so) and remember seeing how much had changed on the radar in that span of time (the lead supercell in southern Indiana had developed and was producing tornadoes). That's the most impressive radar display I've seen for this area since the WSR-88Ds were installed in the 90s.
  4. Check this page for trouble tickets at ASOS sites http://www3.amss.nws.noaa.gov/amsstt.nsf/wFramesetTickets?OpenFrameSet Right now, that site isn't listed as having an issue, but will likely show up since it has the $ maintenance indicator in the metars.
  5. 4 PM obs: CVG 100 LUK 102 (Lunken Field) DAY 100 FFO 101 (Wright-Patterson) CMH 99 LCK 100 (Rickenbacker) IND 104 GEZ 103 (Shelbyville) BAK 102 (Columbus, IN) MIE 103 BMG 101 HUF 104 SDF/LOU/LEX 100 EVV/HNB 106
  6. It's been like that for at least 2 weeks. Need to check the station locator history (it's down as well).
  7. This website was created to post the findings of the reanalysis team, but nothing is happening there so far: http://www.tristatetornado.org/ The powerpoint presentation by Doswell is still available through archive.org http://web.archive.org/web/20080307215010/http://apollo.lsc.vsc.edu/ams/AMS+VP/Storm+Conference/NESC+Presentations/32ndNESC_Presentation/Banquet/Doswell.ppt Reanalysis of surface data revealed that the storm likely formed ahead of the low and just north of the warm front. Information collected a few years ago pointed to a single tornado with a path of about 234 miles (there was still some data voids).
  8. Here's the updated tornado track placefile for GrLevelX that now includes surveys from all of the affected areas. There was some missing information, such as the start/end times for the tornadoes in the MRX area. A tornado listed in Ewing, VA didn't have any path information, so a short segment is drawn here. I tried to avoid straight lines for the longer tracks, so those contain multiple lat/lon values. The tool tip (mouse hover) contains the intensity, time, length, width and fatalities/injuries (if that was available). Some of the shortest tracks don't show up at the default zoom value, so zooming is required to see them. 030212 Tornado Tracks Placefile.txt
  9. Video of the Crittenden, KY tornado crossing I-75
  10. Wilmington is adding maps and radar images today http://www.erh.noaa.gov/iln/events/20120302/
  11. I've been working on a GRLevelX placefile that contains the tornado tracks from March 2/3. Right now it only includes survey results from ILN, LMK and PAH. Also the tornado near Charlotte, NC. 030212 Tornado Tracks Placefile.txt
  12. PUBLIC INFORMATION STATEMENT...UPDATED NATIONAL WEATHER SERVICE WILMINGTON OH 425 PM EST MON MAR 5 2012 ...UPDATED INFORMATION ON CAMPBELL/PENDLETON COUNTY EF3 TORNADO IN KENTUCKY WHICH ALSO MOVED THROUGH CLERMONT/BROWN COUNTIES IN OHIO... LOCATION...NEAR PEACH GROVE KENTUCKY TO NEAR HAMERSVILLE OHIO DATE...MARCH 2 2012 ESTIMATED TIME...440 PM EST MAXIMUM EF-SCALE RATING...EF3 ESTIMATED MAXIMUM WIND SPEED...160 MPH MAXIMUM PATH WIDTH...1/4 MILE PATH LENGTH...23 MILES BEGINNING LAT/LON...38.84N / -84.35 W ENDING LAT/LON...38.90N / -83.98 W * FATALITIES...3 * INJURIES...UNKNOWN * THE INFORMATION IN THIS STATEMENT IS PRELIMINARY AND SUBJECT TO CHANGE PENDING FINAL REVIEW OF THE EVENT(S) AND PUBLICATION IN NWS STORM DATA. ..SUMMARY THE NATIONAL WEATHER SERVICE IN WILMINGTON OH HAS CONFIRMED AN EF3 TORNADO FROM NEAR PEACH GROVE KENTUCKY TO NEAR HAMERSVILLE OHIO ON MARCH 2 2012. ** UPDATED INFORMATION BELOW ** AN ADDITIONAL STORM SURVEY WAS CONDUCTED ON MONDAY MARCH 5TH TO DETERMINE IF THE EF3 TORNADO THAT AFFECTED CRITTENDEN/PINER/MORNING VIEW KENTUCKY WAS THE SAME TORNADO THAT AFFECTED PEACH GROVE KENTUCKY AND ACROSS THE RIVER INTO MOSCOW AND HAMERSVILLE OHIO. THE SURVEY FOUND THAT THERE IS A DEFINITE BREAK IN THE DAMAGE PATH ACROSS SOUTHWEST CAMPBELL COUNTY...WHICH IS CORROBORATED BY EYEWITNESS REPORTS SOUTH OF CLARYVILLE THAT THE FUNNEL WAS NOT IN CONTACT WITH THE GROUND AS IT CROSSED AREAS OF SOUTHWEST CAMPBELL COUNTY. THEREFORE...THE TWO EF3 TORNADOES ARE COUNTED AS SEPARATE TORNADOES...AND NOT ONE CONTINUOUS DAMAGE PATH. THE TORNADO TOUCHED DOWN INITIALLY IN SOUTHCENTRAL CAMPBELL COUNTY KENTUCKY NEAR PEACH GROVE ROAD /HIGHWAY 154/ AND CROSSED FISHER ROAD NORTHWEST OF PEACH GROVE...KENTUCKY. THE TORNADO CROSSED INTO PENDLETON COUNTY AFTER PRODUCING HIGH-END EF3 DAMAGE ON REIS RIDGE ROAD NEAR THE CAMPBELL AND PENDLETON COUNTY LINE. IN PENDLETON COUNTY...THE TORNADO MOVED ACROSS MAYS ROAD PRODUCING SIGNIFICANT AND WIDESPREAD EF2 TO LOW-END EF3 DAMAGE. THE TORNADO THEN CROSSED THE AA HIGHWAY IN PENDLETON COUNTY...AND EVENTUALLY THE OHIO RIVER AFTER CROSSING KENTUCKY HIGHWAY 8 IN PENDLETON COUNTY. THIS TORNADO HIT MOSCOW OHIO WHERE EF3 DAMAGE WAS NOTED...AND CONTINUED ON THE GROUND ACROSS CLERMONT COUNTY AND LIFTED SOUTH OF HAMERSVILLE IN WESTERN BROWN COUNTY. THIS TORNADO CAUSED EXTENSIVE DAMAGE TO STRUCTURES AND TREES ALONG ITS ENTIRE PATH ON BOTH SIDES OF THE RIVER. NUMEROUS HOMES WERE VERY HEAVILY DAMAGED OR DESTROYED...WITH MANY LOSING ROOFS...HAVING COMPLETE EXTERIOR WALL FAILURE...AND EVEN SOME MODULAR HOMES WERE COMPLETELY REMOVED FROM THEIR FOUNDATIONS...LIFTED...AND THROWN IN EXCESS OF 100 YARDS WHERE THEY WERE DESTROYED. ALSO OF NOTE ON THE SURVEY...WAS THE PRESENCE OF A LARGE AREA OF /NON-TORNADIC/ STRAIGHT-LINE WINDS ESTIMATED IN EXCESS OF 100 MPH ON THE SOUTHERN FLANK OF THE TORNADIC DAMAGE. THIS WAS PARTICULARLY NOTICEABLE IN PENDLETON COUNTY NEAR PEACH GROVE. THIS WIND DAMAGE ALSO CONSISTED OF NUMEROUS BARNS AND OUTBUILDINGS DESTROYED...AND CONSIDERABLE HOME AND TREE DAMAGE. THE DEGREE OF DAMAGE WITHIN THE TORNADIC CIRCULATION SUPPORTS WIND SPEED ESTIMATES UP TO 160 MPH...NEAR THE TOP OF THE EF3 CRITERIA.
  13. Here's two videos I created from radar loops of the supercell pair that moved through Northern Kentucky and Southern Ohio yesterday. The lead storm's hook echo passed about 5-6 nautical miles from the TCVG radar with enhanced reflectivity at the end of the hook curl. Check the 1080p option to see the full size. Scans from the TCVG radar From the KILN radar
  14. First severe thunderstorm warning just went up north of Springfield, MO for quarter size hail. Storm topping out at about 37,000 feet.
  15. AVSET is supposed to reduce volume scan time, but I'm not sure of it's status. http://www.roc.noaa.gov/wsr88d/NNOW/AVSET.aspx http://www.roc.noaa.gov/wsr88d/NewRadarTechnology/NewTechDefault.aspx From the AMS Radar Conference paper listed there: "The basic premise of AVSET is to terminate the current volume scan after the radar has scanned all of the elevations with operationally important returns. In other words, once the data collection elevation overshoots the significant radar returns, the volume scan is terminated because there is no operational benefit realized by continuing the execution of the current volume scan, and a new volume scan is begun. The net effect of AVSET is to shorten the elapsed time between data collection on low elevation angles during periods when no significant data are available on the higher elevation tilts."
