After 2 hard days of driving we arrived in North Platte, Neb., late Tuesday. The day’s storms were farther west, yet, but did blow over us late in the evening with striated shelf clouds, frequent lightning and 60-mph wind gusts propelling dust across the parking lots outside our hotel. It looks like very similar supercells — produced largely by upslope flow against the higher terrain of the High Plains/Rockies and then spun by strong winds aloft changing direction and/or speed with height — are likely over the next 3 days in this same general region, perhaps sinking southward with time.
We hope to have more photos posted in days to come.
