stormchase around the Midwest just a few days after the devastating deadly
outbreak of late April 2011. Using NOAA's SPC guidance and some mobile
internet we purchased from a Radioshack (before the days of 4G phones), we
predicted and hunted down this lonely supercell in NE Texas near
Longview/Ore City, with dangerous positive-flash lightning barrages, newly
forming RFDs, redeveloping mesocyclones, day darkness and scud funnels.
Tornados were reported to the SPC but we didn't see any given the base was
incredibly low and was often obscured behind trees.
We also repositioned a
lot as we were worried about getting munched by hail. We saw a few
scud-funnels though. Temperature in the warm plume was around 28-30C with
around 20C dewpoints, with between 2000 and 2500 Joules of CAPE.
