MESOSCALE DISCUSSION 0590
NWS STORM PREDICTION CENTER NORMAN OK
0614 PM CDT TUE MAY 10 2016

AREAS AFFECTED...CENTRAL/SOUTHERN NEBRASKA AND FAR NORTHERN KANSAS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

VALID 102314Z - 110045Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...ISOLATED THUNDERSTORMS ARE POSING A HAIL THREAT IN THE
DISCUSSION AREA ATTM.  TRENDS ARE BEING MONITORED FOR A POSSIBLE
SEVERE THUNDERSTORM WATCH ISSUANCE.

DISCUSSION...A COUPLE OF STORMS IN THE DISCUSSION AREA HAVE MATURED
AND POSE PRIMARILY A HAIL THREAT...WITH ISOLATED SEVERE WIND GUSTS
ALSO POSSIBLE.  THESE STORMS ARE IN AN ENVIRONMENT CHARACTERIZED BY
WEAK TO MODERATE MID-LEVEL INSTABILITY /AROUND 1000-1500 J/KG
MUCAPE/ AND 30-40 KNOTS OF DEEP SHEAR.  LOW-LEVEL SHEAR IS A BIT
WEAK DUE TO WEAK LOW-LEVEL WIND FIELDS...BUT THE AFOREMENTIONED
CAPE/SHEAR COMBINATION AND CONVERGENCE ALONG A SOUTHWARD-MOVING COLD
FRONT WILL SUSTAIN ONGOING CONVECTION DURING THE EVENING.  AT THIS
TIME...CONVECTIVE COVERAGE OF STORMS IS IN QUESTION...AND ANY
INCREASE WOULD REQUIRE A SEVERE THUNDERSTORM WATCH ISSUANCE.  TRENDS
ARE BEING MONITORED.
