PACKAGE. BEST CAPES AND INSTABILITY LIES OVER EASTERN COLORADO AND

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GOODLAND KS
1040 AM MDT SAT JUL 22 2000

HERE IS THE HAZARDOUS WEATHER OUTLOOK FOR NORTHWEST KANSAS...
SOUTHWEST NEBRASKA...AND FAR EASTERN COLORADO.

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND EVENING.

HIGH PRESSURE CONTINUES TO BUILD INTO MUCH OF THE TRI-STATE AREA
FROM THE NORTHEAST LATE THIS MORNING. THE ATMOSPHERE CONTINUES TO
SLOWLY STABILIZE AS DRIER AIR WORKS INTO THE AREA. A WEAK UPPER
LEVEL DISTURBANCE IN THE AREA MAY PRODUCE A FEW THUNDERSTORMS LATER
THIS AFTERNOON.

FURTHER SOUTH AND WEST...OVER FAR EASTERN COLORADO AND GREELEY COUNTY
KANSAS...THE ENVIRONMENT IS A BIT MORE FAVORABLE FOR THUNDERSTORMS TO
DEVELOP. AN INSTABILITY AXIS CONTINUES TO DEVELOP IN THIS AREA WHERE
MID LEVEL MOISTURE IS MORE ABUNDANT. ADDING A FAVORABLE WIND PROFILE
TO STRONG DAYTIME HEATING WILL YIELD THUNDERSTORM DEVELOPMENT THIS
AFTERNOON AND EVENING. THE PRIMARY THREAT WOULD BE LARGE HAIL AND
DAMAGING WINDS. A TORNADO IS ALSO POSSIBLE.
