Area forecast discussion, Jun 13, 1:55 PM CDT, 2 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 154 PM CDT (1254 PM MDT) SAT JUN 13 1998 ...MAIN PROBLEM IS THIS AFTERNOON AND TONIGHT...STORMS AND THE SEVERITY THEREOF... NICE UPPER SYSTEM MOVING EAST TOWARD THE CWA AT THIS TIME AS SFC LOW SPINS UP IN NORTHEAST CO. JET PUNCHING IN OVER SOUTHERN PORTIONS OF CWA WITH COLD POOL PROGGED (BY EXTRAPOLATION...NOT BY MODEL) TO PASS OVER NORTHERN SECTIONS OF CWA. BEST PRESSURE FALLS INDICATE THAT LOW WILL TRACK EAST ACROSS SOUTHERN NEBRASKA... LIKELY PULLING WARM FRONT NORTH TOWARD SOUTHERN NEBRASKA AS WELL. LIKE THE SPC OUTLOOK FOR MODERATE...MAY HAVE MOVED IT A BIT FARTHER NORTH AND WEST...BUT NOT MUCH. CAP STILL FORMIDABLE...BUT EXPECT IT TO BREAK WITH STRENGTH OF SYSTEM. CONVERGENT AXIS EXTENDING FROM SOUTHEAST PANH OF NEBRASKA DOWN INTO NORTHWEST KANSAS...AND EXPECT INITIAL THUNDERSTORM DEVELOPMENT ALONG THAT AXIS AROUND 4 TO 5 PM. THINK STORMS WILL RAPIDLY BECOME SEVERE WITH WIND FIELD AND CAPE TO SUPPORT ISOLATED TORNADOES ALONG AND NEAR THE WARM FRONT...ESPECIALLY. WILL NEED TO WATCH NORTH OF THE WARM FRONT AS WELL...SEEING THAT BOUNDARY LAYER IS NOT WHAT ONE WOULD CALL STABLE. STILL...HIGHEST THREAT CLOSER TO WARM FRONT. TONIGHT EXPECT NUMEROUS THUNDERSTORMS...WILL GO WITH CATEGORICAL FOR ALL BUT PANHANDLE COUNTIES. WOULD LIKE WORDING OF SEVERE IN FOR ALL AREAS. AS LOW PULLS EAST...WINDS SHOULD REMAIN HIGH AND SWITCH TO NORTHWEST...CONTINUING THAT WAY INTO SUNDAY. MODELS DIFFER ON DETAILS FOR THIS AFTERNOON AND EVENING...AND I AM DEVOTING MOST OF MY TIME TO MESOANALYSIS OF THE SHORT-TERM SEVERE THREAT...SO WILL HAVE LITTLE INPUT TO 2ND THROUGH 4TH PERIODS. BEST GUESSES AT NUMBERS BELOW...BUT I HAVE PUT LITTLE TIME IN ANALYZING LATER PERIODS. PRELIMINARY GUIDANCE FOR COORDINATION ONLY. OFFICIAL FORECASTS CONTAINED WITHIN PRODUCT OMAZFPNE.

NEZ004>010-022>029-035>038-056>059-069>071-141200- SEVERE WEATHER OUTLOOK FOR WESTERN AND NORTH CENTRAL NEBRASKA... NATIONAL WEATHER SERVICE NORTH PLATTE NE 1130 AM CDT (1030 AM MDT) SAT JUN 13 1998 THIS OUTLOOK PERTAINS TO THE FOLLOWING NEBRASKA COUNTIES... ARTHUR BLAINE BOYD BROWN CHASE CHERRY CUSTER DEUEL FRONTIER GARDEN GARFIELD GRANT HAYES HOLT HOOKER KEITH KEYA PAHA LINCOLN LOGAN LOUP MCPHERSON PERKINS ROCK SHERIDAN THOMAS WHEELER ...STORM SPOTTER ACTIVATION WILL BE REQUIRED THIS AFTERNOON AND TONIGHT IN WESTERN AND NORTH CENTRAL NEBRASKA... THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS OVER PART OF THE OUTLOOK AREA FOR THIS AFTERNOON AND TONIGHT. THIS AREA IS GENERALLY EAST AND SOUTH OF A LINE FROM CURTIS TO NORTH PLATTE TO DUNNING TO BURWELL. THE REMAINDER OF THE OUTLOOK AREA HAS A SLIGHT RISK FOR SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT. EVEN THOUGH THE TERM SLIGHT IS USED TO DESCRIBE THE RISK FOR THE REMAINDER OF THE AREA...IT REFERS MAINLY TO AREAL COVERAGE. PLEASE UNDERSTAND THAT SEVERE STORMS ARE EXPECTED OVER THE ENTIRE OUTLOOK AREA THIS AFTERNOON AND EVENING...AND ON INTO THE NIGHT FOR NORTHCENTRAL NEBRASKA. AN UPPER LEVEL STORM SYSTEM WILL MOVE EAST OUT OF THE CENTRAL ROCKIES AND INTO NORTHEAST COLORADO THIS AFTERNOON...THEN MOVE EAST ALONG THE NEBRASKA/KANSAS BORDER OVERNIGHT. IN ADDITION...A STRONG SURFACE LOW PRESSURE SYSTEM WILL MOVE FROM NORTHEAST COLORADO INTO SOUTHWEST NEBRASKA THIS AFTERNOON...AND ALSO MOVE EAST ALONG OR JUST NORTH OF THE NEBRASKA/KANSAS STATE LINE TONIGHT. THE COUNTERCLOCKWISE CIRCULATION AROUND THE SURFACE LOW PRESSURE SYSTEM WILL BRING WARM AND MOIST AIR NORTHWARD INTO THE REGION THROUGHOUT THE DAY...AND THE UPPER LEVEL SYSTEM WILL BRING COLDER TEMPERATURES ALOFT. THIS COMBINATION WILL RESULT IN AN UNSTABLE AIRMASS...CAPABLE OF PRODUCING SEVERE THUNDERSTORMS OVER THE ENTIRE OUTLOOK REGION. THE WIND FIELD WILL ALSO BE CONDUCIVE TO SEVERE THUNDERSTORM FORMATION...ESPECIALLY IN THE MODERATE RISK AREA. THERE...THE COMBINATION OF THE WIND PROFILE...MODERATE LOW LEVEL MOISTURE AND WARMTH...AND PROXIMITY TO A WARM FRONT THAT WILL DEVELOP AND MOVE NORTHWARD INTO THE AREA THIS AFTERNOON...WILL RESULT IN CONDITIONS FAVORABLE FOR TORNADOS. STRONG STRAIGHT-LINE WINDS AND LARGE HAIL ARE ALSO POSSIBLE. IN THE REMAINDER OF THE OUTLOOK AREA...TORNADOES ARE POSSIBLE BUT LESS LIKELY...WITH THE MAIN THREATS BEING LARGE HAIL AND STRAIGHT-LINE WINDS. PLEASE STAY IN TOUCH WITH WEATHER INFORMATION THIS AFTERNOON AS CONDITIONS COULD DETERIORATE QUICKLY ONCE THUNDERSTORMS BEGIN. INITIAL THUNDERSTORM DEVELOPMENT IS EXPECTED OVER THE EASTERN NEBRASKA PANHANDLE AND SOUTHWEST NEBRASKA BY 5 PM...WITH STORMS MOVING AND DEVELOPING EASTWARD AN NORTHEASTWARD AS THE EVENING PROGRESSES.
