November 11, 2015 – Southern Iowa

November 11th presented an opportunity for the first chase in a while. A powerful system with a 120kt 500mb jet was moving into the Central Plains atop a deepening surface low that was going to pull 60 degree dewpoints into the target area. Coupled with a strong low level jet in the 60-70kt area provided more than adequate shear atop marginal to modest instability through southern Iowa and Northern Missouri.

Still recovering from the long drive back home on the 22nd, another chance for severe weather in Iowa presented itself for the 24th and only being home for 24 hours before heading back there made me question my sanity. Nevertheless, the storms are a callin’ and the forecast looked decent enough for me to pull the trigger.

June 20th through the 22nd looked like a decent opportunity for a three day chase. The 20th featured a belt of westerlies across the northern portion of the CONUS while a low with attendant cold front in the Dakotas was progged to drift to the southeast into the midwest. East of the front, the warm sector looked to be characterized by a moderately unstable airmass with MLCAPE approaching the 4,000 J/Kg area as temperatures were expected to be in the low 80s with low 70 dewpoints.

May 10th was the last day of my 5 day mini chasecation and although there was an enhanced risk of severe weather along the Missouri River into Iowa, having to work the following day limited how long I could hang out in the target area. Nevertheless, it was on the way home and I may as well give it a shot. SPC had outlined two areas of enhanced risk, along the Missouri River from Sioux Falls through Iowa  and the southern target in Texas near the Dallas-Fort Worth Metroplex.
