Severe Thunderstorm Warning 166, NWS Goodland, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
200 PM MDT SAT JUL 5 2003

FORECAST CONCERNS ARE ON THE CHANCES OF ISOLATED CONVECTION AS WELL
AS CONTINUATION OF ABOVE NORMAL TEMPERATURES THROUGH THE NEXT 7
DAYS.

TONIGHT...BEST INSTABILITY AXIS EXTENDS FROM NORTHEAST TO SOUTHWEST
WHERE CURRENT SATELLITE HAS TOWERING CUMULUS DEVELOPING ABOUT 3
HOURS EARLIER THAN THIS TIME YESTERDAY. HOWEVER...AS WAS THE CASE
LAST NIGHT CIN VALUES JUST A BIT TOO MUCH FOR SCATTERED ACTIVITY AS
VALUES ARE GREATER THAN 50 J/KG PER 12Z ETA. WILL KEEP ANY POPS VERY
LOW AND ONCE SUNSET APPROACHES DONT EXPECT TO SEE MUCH OF ANYTHING
LEFT. WINDS WILL CONTINUE FROM THE SOUTH TO SOUTHWEST WITH WINDY
CONDITIONS EARLY EAST AND SOUTH OF THE SURFACE BOUNDARY. MINS NEAR 65
WEST TO NEAR 70 EAST.

SUNDAY...SURFACE TROUGH LINGERS ACROSS THE AREA WITH INSTABILITY
AXIS ONCE AGAIN SETTING UP FROM NORTHEAST TO SOUTHWEST ACROSS THE
AREA. CIN VALUES ARE LESS THAN 30 J/KG FROM NEAR KMCK THROUGH KGLD
TO NEAR TRIBUNE. COULD SEE A FEW STORMS NORTH OF THE INTERSTATE IN
THIS INSTABILITY AXIS AS FURTHER SOUTHWEST 700 TEMPS GREATER THAN
+16C. WITH SOME INCONSISTENCIES REGARDING CIN VALUES AND 700 TEMPS
FROM 00Z RUNS TO 12Z RUNS WILL ONLY KEEP SLIGHT CHANCE POPS AT THIS
POINT. OTHERWISE...CONTINUED HOT. LOOKS LIKE A CHANCE OF POPS WILL
BE NEEDED SUNDAY NIGHT AS A MODEST 500 VORT MAX/LOW LEVEL JET...AND
INCREASING 250 JET WINDS ASSIST SOME EVENING AND OVERNIGHT PRECIP
ALONG THE 700 MB THETA-E AXIS. THE SUGGESTION OF PRECIP IS ADVERTISED
BY THE ETA/NGM/GFS. WILL TREND TOWARD THE WARMER ETA/UKMET WITH
READINGS 100 TO 105. LOWS AGAIN 65 WEST TO NEAR 70 EAST.

MONDAY...STATIONARY FRONT STRUGGLES TO PUSH THROUGH THE AREA...
GETTING HUNG UP FROM NORTHEAST TO SOUTHWEST ACROSS THE AREA.
MOISTURE AND LIFT ARE ALL PRESENT ONCE AGAIN WITH THE QUESTION BEING
HOW STRONG IS THE CAP. LATEST ETA SHOWS 30-50 J/KG OF CIN SO SLIGHT
CHANCE WORDING IS WARRANTED ONCE AGAIN. HIGH TEMPS A BIT COOLER WITH
LOWER 90S NORTHWEST TO NEAR 100 EAST/SOUTHEAST.

TUESDAY...WEAK FRONT BACKS INTO NORTHERN PART OF THE AREA BUT RELIEF
FROM HEAT ALSO NIL AS 850 TEMPS SUPPORT HIGHS NEAR 100 ONCE AGAIN.
WITH 700 MB TEMPS GREATER THAN +16C WILL PULL CHANCES OF PRECIP.
WILL NEED TO WATCH NORTHERN PART OF THE AREA THOUGH AS SLIGHTLY
COOLER TEMPS ARE FORECAST AND THE FRONT AS A FOCUS.

IN THE EXTENDED FORECAST (WEDNESDAY-SATURDAY)...UPPER LEVEL RIDGE IS
THE DOMINANT WEATHER FEATURE DURING THE 4 TO 7 DAY PERIOD. LATEST
LONG RANGE GUIDANCE REMAINS IN GENERAL AGREEMENT WITH PREVIOUS RUNS
IN KEEPING THE FORECAST AREA HOT AND DRY. TEMPERATURES THROUGH THE
PERIOD AROUND THE 100 DEGREE MARK WITH OVERNIGHT LOWS IN THE LOW/MID
60S WEST TO NEAR 70 EAST. CONVECTIVE CHANCES CLOSE TO NIL GIVEN 700
TEMPS +16C AND HIGHER. WILL KEEP FORECAST DRY.

.GLD...NONE.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GOODLAND KS
1022 AM MDT SAT JUL 5 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST KANSAS...EXTREME
SOUTHWEST NEBRASKA...AND EAST CENTRAL COLORADO.

.DAY ONE...TODAY AND TONIGHT

A VERY WARM AND DRY AIR MASS SITUATED ACROSS THE TRI STATE AREA WILL
MAKE IT DIFFICULT FOR THUNDERSTORMS TO DEVELOP TODAY. HOWEVER...
ISOLATED STORMS CANNOT BE RULED OUT. IF ANY STORMS DEVELOP...THE
MAIN THREAT WOULD BE DAMAGING WIND AND POSSIBLY SOME LARGE HAIL.

HEAT WILL ALSO BE A CONCERN AGAIN TODAY ACROSS THE TRI STATE AREA.
TEMPERATURES ARE FORECAST TO RANGE FROM THE UPPER 90S IN FAR EASTERN
COLORADO TO 103 AT HILL CITY...SO DRINK PLENTY OF WATER TO REMAIN
HYDRATED. IF YOU FEEL FAINT IN THE HEAT...GO INSIDE AN AIR
CONDITIONED BUILDING IMMEDIATELY. ON AVERAGE HEAT KILLS 175 CITIZENS
NATIONWIDE EACH YEAR...SO TAKE THE THREAT OF DANGEROUS HEAT
SERIOUSLY.

HIGH TEMPERATURES AND LOW RELATIVE HUMIDITIES WILL PRODUCE EXTREME
FIRE CONDITIONS TODAY. ALL OUTSIDE BURNING SHOULD BE AVOIDED IN
AREAS WITH EXTREME FIRE DANGER.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR A TROUGH OF LOW PRESSURE
IN EASTERN COLORADO SUNDAY AFTERNOON AND MOVE ACROSS THE TRI
STATE AREA SUNDAY EVENING. THESE STORMS WILL LIKELY BE HIGH BASED
WITH THE MAIN THREAT BEING DAMAGING WIND. AN ISOLATED STORM COULD
PRODUCE LARGE HAIL. LATE DAY THUNDERSTORMS WILL BE POSSIBLE THROUGH
TUESDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY OR TONIGHT.
