1057 AM CDT THU MAY 20 1999

...A FEW SPOTTERS MAY BE NEEDED THIS AFTERNOON AND EARLY
THIS EVENING...

VERY UNSTABLE AIR ACROSS SOUTHWEST KANSAS CONTINUES THIS AFTERNOON
WHILE AN UPPER LEVEL DISTURBANCE IS MOVING NORTHEAST ACROSS THE
AREA.  THIS WOULD NORMALLY SIGNAL A STRONG RISK FOR SEVERE STORMS BY
AFTERNOON.  HOWEVER...DIFFICULTIES TODAY REVOLVE AROUND WIDESPREAD
CLOUD COVER.  AS LONG AS THE CLOUD REMAINS...HEATING BY THE SUN WILL
BE REDUCED WHICH WILL SERVE TO LIMIT THE INSTABILITY AND INHIBIT THE
SEVERITY OF ANY STORMS THAT DEVELOP.  MOST AREAS SOUTH AND EAST OF A
DIGHTON...GARDEN CITY...ULYSSES...ELKHART LINE WILL WANT TO HAVE A
FEW STORM SPOTTERES AVAILABLE.  ESPECIALLY IF THE AFTERNOON BRINGS
A LOT OF SUNSHINE TO THE AREA.

AS MENTIONED EARLIER THIS MORNING...THE MAIN THREAT WITH ANY STORMS
THAT DEVELOP WOULD BE FROM HAIL AND STRAIGHT LINE WIND.
