The long standing Iowa bust curse has ended!
Scott Kampas and I intercepted a tornado... near Charles City, Iowa on Friday, June 11 (near the town of Riceville, IA and later, Leroy, MN). This was the first Iowa tornado intercept for both of us ever - and officially breaks the five year stint of convective-free; and or convectively messy chases to the Hawkeye state. While I still find Iowa annoying (the masses of flys, odd roads within towns such as Charles City, and the like); the Friday chase was both enjoyable and satisfying. Scott and I ended up following the cell north into S. CEN. MN towards our original target region of Albert Lea. The surface conditions relative to the storm were amazing ... considering LCLs were at 1000mb; and exhibited multiple "scud-puppies" (which looked like multiple vortices) at treeline and ground level. Scott phoned this into NWSFO La Crosse, WI (as we were in their CWA); which somewhat debunked public reports of multiple tornado sightings. The chase concluded in Rochester, MN at a local Subway on some local road... followed by a breathtaking rainbow (with lightning between the bow); and "stormset" (sunset).
I phoned Vince Miller; whom provided us with an idea of what to expect on Saturday. Being primarily w/o data (very "Hoadley'esque these days; myself especially); Scott and I had a feeling Kansas would be the main play, but were not certain. Vince mentioned E. CEN. Kansas E of I-35 as being the focus for convective development on Saturday... yet it wasn't until the following morning at the Osceola, Iowa library that we became thrilled at the potential Saturday held. Two plays; one in S. CEN. KS near ITC; the other near Concordia to Manhattan in NE/N. CEN KS. We favored the N target due to a nice 850/700mb jet streak/wave progd. for early evening; that coupled with excellent surface flow; possible outflow boundary from early morning convection sinking southward (this hurt us later); and a nice theata-E tongue pointing right towards the Junction City, KS region and points northward. South we proceeded; forgoing the first TOR warned convection of the day in S. CEN. NE. Waited, waited, and waited some more at Junction City, KS; then in a 10-minute timeframe... our storm initiated and exploded just to our N. Scott and I headed N on HW77 and intercepted the storm; just as it became undercut by a southward moving bow echo. Shucks... we *almost* had a tornado with this storm. Had it not been undercut, a significant tornado would have been very possible.
Blew off this storm and headed W towards Concordia on HW24. TOR warned storm which was pretty for about 15 minutes before it too was undercut. Nice meso(s) with this tail end line storm... but no dice. Called off the chase in Concordia with a breathtaking sunset and lightshow above the KFC sign. The real kicker came about 15 hours later... following staying the evening at "The Big Inn" at Greenwood, NE... we departed back to IA (where Scott's car was stationed) due to academic and work related commitments. As we pressed E on I-80 near OMA; strong E/SE backed winds were noted; but the temp and Td were not extremely conducive (in our minds) for convective initiation until late in the day (when we couldn't chase)... alas, we headed E across the 18 state SLGT risk region (only hitting four states during the trip home)... and then heard about the tornadic supercells after the fact.
Never fails! Ah well; it was a great weekend, and now its time to get back to reality. Academia, work, and other random duties will keep me home for a good portion of the rest of the spring... *unless* its on a weekend and its another June 24, 2003!
Many thanks to Vince Miller, Chris Novy, Mark Sefried, Bill Reid, Jim Leonard, and Scott Weberpal for intput, nowcasting at times, and interesting inter-cell phone debauchery.
Scott K.... Excellent job navigating and thank you for tolerating my jackassery within the vehicle ;0)
