SPC MD 1410MD 1410 CONCERNING SEVERE THUNDERSTORM WATCH 426... FOR PARTS OF WEST CENTRAL THROUGH NORTH CENTRAL NEBRASKA 
Mesoscale Discussion 1410 NWS Storm Prediction Center Norman OK 1048 PM CDT Tue Jun 30 2026
Areas affected...parts of west central through north central Nebraska
Concerning...Severe Thunderstorm Watch 426...
Valid 010348Z - 010545Z
The severe weather threat for Severe Thunderstorm Watch 426 continues.
SUMMARY...A swath of potentially damaging wind gusts appears likely to overspread the region through midnight-2 AM CDT.
DISCUSSION...03Z surface observations indicate that a 2-4 mb 2-hourly surface pressure perturbation has developed with an evolving cluster of storms now beginning to propagate east-northeast of the Cheyenne Ridge vicinity. This includes rises centered near/north of Akron CO and falls east-northeastward across Ogalala through North Platte NE, with perhaps a developing wake low near Pine Bluffs NE.
Rapid destabilization has occurred the past few hours in a narrow corridor east-northeast of the evolving cluster in response to low-level moistening, including surface dew point increases of 8-12 F, which now appears to be supporting CAPE up to 3000 J/kg. A meso-beta scale cyclonic circulation has become better defined, and there appears considerable potential for further convective intensification and at least a bit further upscale growth. An ongoing increase in severe wind gusts appears likely to continue at least several more hours, with a continuing risk for large hail as well.
