Area forecast discussion, Jun 3, 3:35 PM CDT, 3 hours 25 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
235 PM MDT (335 PM CDT) THU JUN 3 1999

THE UPPER LOW WAS DRIFTING SOUTH OVER CALIFORNIA EARLY THIS
AFTERNOON. THE AVN...NGM AND ETA HAVE VERIFIED THE POSITION OF THE
LOW QUITE WELL THROUGH 3/18Z. THIS SYSTEM WAS BECOMING CUT OFF FROM
THE FLOW AND SHOULD LINGER OVER THE SOUTHWEST UNTIL ANOTHER SYSTEM
EJECTS THE CUT OFF LOW EAST BY EARLY SUNDAY ACCORDING TO MODEL
CONSENSUS.

AHEAD OF THIS SYSTEM...GULF MOISTURE HAS BEEN SPREADING NORTH ACROSS
THE FORECAST AREA. THE NGM AND AVN HAVE BEEN TOO DRY THE LAST
SEVERAL RUNS...INCLUDING THIS MORNINGS RUNS. SO HAVE CHOSEN THE ETA
AS THE MODEL OF CHOICE...WHICH IS STILL TOO DRY. DEW POINTS 65-70
EAST OF A LINE FROM IML TO CBK. THE AIRMASS HAS BECOME VERY UNSTABLE
WITH LIS NEAR -10 NEAR HLC.

MAJOR QUESTION IS IF AND WHEN THE CAP WILL BREAK. MODIFIED SOUNDING
INDICATED THE CAP SHOULD BREAK BY 00Z. LOOK FOR TO CONVECTION TO
INITIATE ALONG THE DRY LINE BY THIS EVENING AND THEN MOVE EAST.
GIVEN RELATIVELY WARM MID LEVEL TEMPS...EXPECT OVERALL COVERAGE TO
REMAIN SCATTERED. GIVEN SIGNIFICANT VEERING IN THE LOWER
LEVELS...AND PER COORDINATION WITH SPC...WILL HIGHLIGHT TORNADOES
MOST ZONES FOR THIS EVENING.

FOR FRIDAY...EXPECT VERY LITTLE CHANGE WITH MAINLY EVENING
THUNDERSTORMS.

FOR SATURDAY...THE NGM WAS THE ODD MODEL OUT IN EJECTING THE UPPER
LEVEL SYSTEM TOO FAST AND BRINGING COOLER AIR IN ON SATURDAY. EXPECT
TEMPERATURES SHOULD BE ABOVE 75 DEGREES.

.GLD...TORNADO WATCH UNTIL 9 PM MDT (10 PM CDT) FOR ALL OF NORTHWEST
       KANSAS COUNTIES EXCEPT GREELEY.
