CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 190019Z - 190215Z

SUMMARY...THOUGH STORM COVERAGE IS UNCERTAIN, SOME INCREASE IN
SEVERE POTENTIAL IS ANTICIPATED IN PARTS OF NORTH-CENTRAL NEBRASKA
OVER THE NEXT FEW HOURS. A WATCH IS POSSIBLE.
DISCUSSION...SIGNS OF CONVECTIVE DEVELOPMENT ARE EVIDENT ON VISIBLE
SATELLITE NEAR A WEAK SURFACE LOW IN NORTH-CENTRAL NEBRASKA. SOME
HIGH-BASED ACTIVITY IS ALSO PRESENT FARTHER SOUTHWEST NEAR NORTH
PLATTE. STRONG BUOYANCY HAS DEVELOPED IN CENTRAL NEBRASKA WHERE

THE LOW-LEVEL JET MAY HELP INITIATE ADDITIONAL STORMS BY MID/LATE
EVENING.
