Hail in Nebraska, April 1, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
134 PM CST SAT APR 1 2006

.SHORT TERM...ISSUE IS THE SEVERE WEATHER POTENTIAL TONIGHT.

PRETTY SHARP UPPER LEVEL WAVE COMING THROUGH EASTERN COLORADO
AND NEW MEXICO ON WATER VAPOR THIS MID AFTERNOON. STRONGER JET
LEVEL WINDS SEEN ON THE WIND PROFILERS COMING THROUGH WITH THE
WAVE. DEEP SURFACE MOISTURE CONFINED TO OKLAHOMA SOUTH...BUT
SLOWLY MOISTURE HAS BEEN SPREADING NORTH INTO KANSAS. STRONG
SOUTH WINDS EXPECTED THROUGH THE AFTERNOON.

THIS EVENT IS A QUICK HITTING BUT POTENTIALLY INTENSE WIND
EVENT FOR THE CWFA. WAVE WILL CONTINUE TO LIFT OUT...AND NARROW
MOISTURE AXIS WILL SURGE NORTH IN RESPONSE TO DEEPENING SURFACE
LOW EXPECTED IN WESTERN/NORTH CENTRAL KANSAS BY LATE EVENING.
SEVERE WEATHER PARAMETERS SUPPORT SUPERCELL POTENTIAL...BUT
EVOLUTION OF THE SYSTEMS LOOKS MORE LINEAR WITH EMBEDDED
SUPERCELLS BY LATE EVENING AND EARLY SUNDAY MORNING. SURGE OF
MID LEVEL DRY AIR BY 09Z WILL BE CHANGE POINT TO A FAST MOVING
LINE EVENT CAPABLE OF PRODUCING DAMAGING WINDS. MARGINALLY SEVERE
HAIL POSSIBLE NORTHERN 1/2 OF CFWA...WITH SLIGHTLY LARGER HAIL
POSSIBLE SOUTH. HAVE CONTINUED WITH AN ISOLATED TORNADO IN THE
SOUTHERN CWFA...BUT CONFIDENCE IS LOW...BUT NOT LOW ENOUGH TO REMOVE
IF SOME BOWING SEGMENTS AND EMBEDDED SUPERCELLS DO DEVELOP. DO
ANTICIPATE A SEVERE WEATHER WATCH LATE THIS EVENING...AND ADDED
SEVERE MENTION IN THE SOUTHEAST CWFA. ALSO...PRECIPITABLE WATER
VALUES APPROACH 1.5 IN THE SOUTHEAST CWFA...AND MODELS ARE
CONSISTENT THIS WILL BE AN EFFICIENT RAIN PRODUCER. ADDED QPF
TO THE FORECAST...INCLUDING OVER ONE INCH IN THE SOUTHEAST 1/2
OF THE CWFA.

AS THE LOW SLIDES BY AROUND SUNRISE SUNDAY...MODELS ARE ALL
CONSISTENT WITH PRIMARILY WESTERLY FLOW OVERTAKING THE REGION
BY MID MORNING. REMOVED ANY SEVERE POTENTIAL FOR EARLY SUNDAY
AND SWODY2 NOW HAS THAT TREND. LINGERING PRECIPITATION ON SUNDAY
POSSIBLE...AND PRIMARILY SHOWERS PER MID LEVEL LAPSE RATES...BUT
HESITANT TO COMPLETELY PULL THUNDER MENTION THIS TIME OF YEAR AND
THIS TYPE OF SYSTEM. WINDS MAY BE THE BIGGER CONCERN BY SUNDAY
AFTERNOON...AS WESTERLY FLOW IS WELL ALIGNED THROUGH 700 MB.
HOWEVER...SPEEDS DON/T SHARPLY INCREASE WITH HEIGHT. LOOKS LIKE
BORDERLINE WIND ADVISORY POTENTIAL FOR THE AFTERNOON AND EARLY
SUNDAY EVENING.

NICE DAY MONDAY WITH A LOT QUIETER WEATHER.

.LONG TERM...12Z TUESDAY THROUGH FRIDAY. THE AXIS OF THE UPPER LEVEL
RIDGE ENTERING THE HIGH PLAINS LATE MONDAY WILL MOVE ACROSS THE
REMAINDER OF THE PLAINS ON TUESDAY AND THEN MOVE EASTWARD INTO THE
MISSISSIPPI VALLEY TUESDAY EVENING. AS THE RIDGE DEPARTS TO THE
EAST...A STRONG CLOSED LOW PRESSURE SYSTEM OVER THE WEST COAST WILL
PROGRESS INLAND INTO THE WESTERN STATES. PRESSURE FALLS OVER THE
PLAINS STATES AHEAD OF THE APPROACHING LOW PRESSURE SYSTEM LATE
TUESDAY WILL STRENGTHEN THE LOW LEVEL SOUTHERLY FLOW OVER THE
SOUTHERN AND CENTRAL PLAINS WHICH WILL ENHANCE ADVECTION OF MOISTURE
AND INSTABILITY INTO THE FORECAST AREA. SLIGHT CHANCES OF SHOWERS
AND THUNDERSTORMS WILL DEVELOP AFTER SUNSET TUESDAY EVENING. CHANCES
OF SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO WEDNESDAY AS THE
INCREASINGLY MOIST SOUTHERLY LOW LEVEL FLOW INTERACTS WITH SHORTWAVE
ENERGY EMBEDDED IN A SOUTHWEST FLOW ALOFT AHEAD OF THE APPROACHING
LOW PRESSURE SYSTEM. ADDITIONALLY...STRONG WARM AIR ADVECTION WILL
PUSH HIGH TEMPERATURES INTO THE LOWER TO MID 70S ACROSS THE ENTIRE
FORECAST AREA...WITH TEMPS POSSIBLY CLIMBING INTO THE UPPER 70S TO
NEAR 80 DEGREES OVER THE FAR SOUTHWEST ZONES.

THURSDAY LOOKS TO BE THE MOST ACTIVE DAY OF THE LONG-TERM. DURING
THIS TIME...THE PROGRESSIVE STRONG CLOSED LOW PRESSURE SYSTEM WILL
MOVE THROUGH SOUTH DAKOTA AND WILL DRAG A COLD FRONT THROUGH THE
CENTRAL PLAINS. THE BEST DYNAMICS ASSOCIATED WITH THIS SYSTEM
PRELIMINARILY APPEAR AS THOUGH THEY WILL PASS TO THE NORTH AND THE
SOUTH OF OUR AREA. SURFACE DEW POINTS IN THE LOWER 50S OVER THE
EASTERN FORECAST ZONES WILL ALLOW FOR THE MOST CONCENTRATED ACTIVITY
IN THAT REGION WITH THE POSSIBILITY OF SOME SEVERE HAIL AND WINDS.
THE ACTIVITY WILL BEGIN TO DECREASE ACROSS THE AREA FROM WEST TO
EAST THURSDAY AFTERNOON. RESIDUAL SHOWERS WILL REMAIN OVER THE AREA
THURSDAY NIGHT AS MOISTURE WRAPS AROUND THE CLOSED LOW PRESSURE
SYSTEM WHICH WILL BE MOVING INTO WESTERN IOWA. THE DEPARTING LOW
PRESSURE SYSTEM WILL BE FOLLOWED BY SHORT WAVE RIDGING WHICH WILL
PREVAIL OVER THE PLAINS ON FRIDAY BRINGING A BRIEF RETURN TO FAIR
WEATHER.
