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.
