AREAS AFFECTED...PARTS OF SERN NEB AND ADJACENT N CENTRAL/NERN KS
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 032207Z - 032330Z
SCATTERED STRONG/LOCALLY-SEVERE STORMS CONTINUE TO DEVELOP ACROSS
THIS REGION. WHILE SEVERE POTENTIAL SHOULD REMAIN CONFINED TO A FEW
OF THE STRONGEST STORMS...THREAT POSSIBLY PERSISTING INTO THIS
EVENING COULD REQUIRE WW ISSUANCE.
LATEST RADAR LOOP REVEALS SCATTERED SHOWERS AND STORMS ACROSS THE
SERN QUARTER OF NEB AND INTO ADJACENT N CENTRAL/NERN KS...ON THE SRN
AND WRN FRINGE OF THE UPPER LOW NOW CENTERED JUST W OF OMA /OMAHA
NEB/. DAYTIME HEATING HAS CONTRIBUTED TO THE DEVELOPMENT OF 1000 TO
1500 J/KG MIXED-LAYER CAPE...MAINLY FROM CENTRAL KS/S CENTRAL NEB
WWD. WITH ROUGHLY 30 KT NWLYS ACROSS THE CENTRAL PLAINS...SHEAR IS
SUFFICIENT GIVEN THE DEGREE OF INSTABILITY TO SUPPORT
ORGANIZED/WEAKLY ROTATING STORMS. WSR-88D CONFIRMS THIS...WITH
VELOCITY DATA REVEALING WEAK ROTATION WITH STORMS NOW OVER JEWELL
AND NWRN CLOUD COUNTY.
WITH A MODEST INCREASE IN THE SLY LOW-LEVEL JET FORECAST ACROSS KS
TONIGHT...STORMS MAY PERSIST WELL INTO THE EVENING. GREATEST SEVERE
POTENTIAL APPEARS TO EXIST ACROSS N CENTRAL KS OVER THE NEXT COUPLE
OF HOURS -- WHERE A THREAT FOR PRIMARILY LARGE HAIL IS EVIDENT.
WHILE COVERAGE OF STRONGER CELLS REMAINS LIMITED...AN INCREASE IN
THE NUMBER OF STORMS COULD REQUIRE WW ISSUANCE.
