AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
230 PM CDT THU APR 6 2006

THE FORECAST FOR THIS CYCLE FOCUSES ON SEVERAL PARAMETERS TONIGHT
THROUGH FRIDAY. DISPOSITION OF THE HIGH WIND WATCH AND WARNING IS A
PRIORITY ALONG WITH THE COVERAGE...TYPE AND CHARACTER OF
PRECIPITATION.

.NEAR TERM...
    STRONG COLD ADVECTION IN THE LOWER 100MB OF THE TROPOSPHERE WILL
ALLOW FOR THE 45-55KT WIND AT 800MB TO MIX DOWN TO THE SURFACE...
ESPECIALLY IN THE WESTERN HALF OF THE STATE. KNOCKING OFF SOME FOR
FRICTION...WE ARE STILL CONSIDERING HIGH END ADVISORY CRITERIA IN
THE CENTRAL AND NORTH CENTRAL ZONES TO LOW END WARNING CRITERIA IN
THE WEST AND SOUTHWEST.
    TURNING ATTENTION TO PRECIPITATION...THE STORM SYSTEM CROSSING
NEBRASKA IS LIKELY TO PRODUCE THUNDERSTORMS INITIALLY WITH ELEVATED
CONVECTION IN THE WRAPAROUND OVER NORTHERN AND WESTERN NEBRASKA
UNTIL ABOUT 06Z WHEN IT STRATIFIES. BECAUSE 850-700MB THICKNESS IS
AT OR BELOW 1545M AT 12Z...SNOW WILL PROBABLY MIX WITH THE RAIN IN
THE WEST UNTIL EARLY FRIDAY AFTERNOON. THEN...THE PRECIPITATION IS
EXPECTED TO TAPER OFF FROM THE NORTH.
    A QUIET PERIOD IS THEN EXPECTED SATURDAY AND SUNDAY WITH WARMER
TEMPERATURES AS AN UPPER RIDGE MOVES OVER THE PLAINS.
&&

.EXTENDED...
    RETURN FLOW BEGINNING SUNDAY WILL BRING GULF MOISTURE UP INTO
CENTRAL AND WESTERN NEBRASKA AHEAD OF ANOTHER FRONT/STORM SYSTEM.
THE FRONT IS EXPECTED TO CROSS NEBRASKA MONDAY NIGHT AND TUESDAY.
CONVERGENCE WITH THE SYSTEM AND ELEVATED FRONTOGENESIS WILL GENERATE
ENOUGH LIFT FOR PRECIPITATION TO DEVELOP. THE 800MB BASED LIFTED
INDICES INDICATE INSTABILITY...SO THE CHARACTER OF THE PRECIPITATION
WILL BE CONVECTIVE. THUS WE ARE PUTTING IN A CHANCE FOR
THUNDERSTORMS MONDAY NIGHT AND TUESDAY ENDING TUESDAY NIGHT. THEN IT
APPEARS THAT THE NEXT CHANCE IS LATE THURSDAY OR FRIDAY WITH ANOTHER
SYSTEM. FOR THE TIME BEING...WE WILL GO WITH A TOKEN MENTION OF A
SLIGHT CHANCE IN NORTH CENTRAL NEBRASKA THURSDAY AFTERNOON AND
EVENING.
&&

.SYNOPSIS...
    AT 19Z...6.7U IMAGERY SHOWED A MATURE CYCLONE OVER THE
YELLOWSTONE PARK REGION. THE COMPOSITE RADAR IMAGE SHOWED
THUNDERSTORMS ACROSS THE MIDDLE OF SOUTH DAKOTA AND IN CENTRAL
KANSAS. CONVECTIVE DEVELOPMENT WAS ALSO INDICATED IN SOUTHWEST
NEBRASKA IN THE AREA OF ELEVATED FRONTOGENESIS INDICATED BY 6.7U
IMAGERY. ANALYSIS OF THE 19Z MSL DATA SHOWED A 988MB LOW PRESSURE
CENTER IN NORTHWEST KANSAS NEAR HILL CITY AND ANOTHER 989MB CENTER
IN CENTRAL NEBRASKA SOUTHEAST OF KEARNEY. A COLD FRONT WAS STRETCHED
FROM THE KANSAS LOW INTO THE OKLAHOMA PANHANDLE WEST OF GAGE. THE
DRY LINE RUNNING FROM EAST OF HAYES AND GREAT BEND KANSAS TO JUST
WEST OF WICHITA.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE NORTH PLATTE NE
612 AM CDT THU APR 6 2006

WESTERN CHERRY-
612 AM CDT THU APR 6 2006 /512 AM MDT THU APR 6 2006/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF WESTERN AND
NORTH CENTRAL NEBRASKA.

.DAY ONE...TODAY AND TONIGHT.

THERE IS A MODERATE RISK OF SEVERE WEATHER EAST OF A LINE FROM
ONEILL TO BURWELL. A SLIGHT RISK OF SEVERE WEATHER EXISTS EAST OF
A LINE FROM VALENTINE TO BROKEN BOW.

A STRONG LOW PRESSURE SYSTEM WILL MOVE OUT ONTO THE HIGH PLAINS
LATER TODAY. IN ADVANCE OF THIS SYSTEM...WARM MOIST AIR WILL BE
TRANSPORTED NORTHWARD INTO MAINLY THE EASTERN HALF OF THE STATE.
BEHIND THE SYSTEM...DRIER AIR WILL MOVE INTO THE WESTERN HALF OF
THE STATE WHICH WILL SET THE STAGE FOR THE POTENTIAL FOR SEVERE
WEATHER DEVELOPMENT THIS AFTERNOON. THIS BOUNDARY BETWEEN THE
WARM...MOIST AIR AND THE DRY AIR...CALLED A DRY LINE...WILL MOVE
INTO PORTIONS OF CENTRAL NEBRASKA BY AFTERNOON. AN UPPER LEVEL
DISTURBANCE WILL TRAVERSE THIS SAME AREA DURING THE AFTERNOON AND
WILL WORK IN TANDEM WITH THE DRY LINE TO PRODUCE A SCATTERED LINE
OF THUNDERSTORMS...MOST LIKELY EAST OF A LINE FROM VALENTINE TO
NORTH PLATTE. THESE STORMS WILL DEVELOP RAPIDLY...AND WILL HAVE
THE POTENTIAL TO PRODUCE LARGE HAIL AND DAMAGING WINDS.

IN ADDITION...WINDS IN THE LOWEST PORTION OF THE ATMOSPHERE WILL
BE SUPPORTIVE OF THUNDERSTORMS HAVING THE CAPABILITY OF PRODUCING
TORNADOES...MAINLY IN AN AREA EAST OF A LINE FROM BROKEN BOW TO
BURWELL TO ONEILL. THOSE PLANNING ACTIVITIES IN THIS AREA WILL
NEED TO CLOSELY MONITOR WEATHER CONDITIONS THROUGH THE DAY.

TONIGHT...AS THE LOW PRESSURE SYSTEM MATURES...WIDESPREAD SHOWERS
AND THUNDERSTORMS WILL DEVELOP FURTHER WEST...ACROSS MUCH OF
WESTERN AND NORTH CENTRAL NEBRASKA. WINDS WILL ALSO INCREASE
DRAMATICALLY OVERNIGHT...WITH WINDS SPEEDS OF 35 TO 45 MPH
POSSIBLE BY MORNING...WITH SOME GUSTS EXCEEDING 50 MPH.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND
TONIGHT...MAINLY EAST OF A LINE FROM NORTH PLATTE TO VALENTINE.
