AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
311 AM CDT WED JUN 13 2007

.SYNOPSIS...
SEMI STATIONARY FRONT EXTENDS NORTHEAST TO SOUTHWEST THROUGH
CENTRAL NEBRASKA SOUTHWEST INTO SOUTHEAST COLORADO. EXTENSIVE SHOWERS
AND EMBEDDED THUNDERSTORMS CONTINUE TO DEVELOP WITH ADDITIONAL
RAINFALL TO KEEP INHERIT FLASH FLOOD WATCH GOING ACROSS THE
SOUTHWEST AND INTO NORTH CENTRAL TODAY AS SATURATED GROUNDS TO
GET MORE RAINFALL.

&&

.DISCUSSION...
MODELS IN AGREEMENT WITH BLOCKING PATTERN OVER THE CONUS TO LINGER
IN THE NEAR TERM. WATER VAPOR IMAGERY AT THIS TIME SHOWS UPPER LOW
OVER NRN NM DRIFTING TO THE SOUTHEAST AS POSITIVELY TILTED RIDGE
AXIS EXTENDS NORTHEAST FROM THE SOUTHERN PLAINS TO THE WESTERN
GREAT LAKES. TODAY THE H5 LOW IS FORECAST TO CLOSE OFF WHILE
LIFTING NORTHEAST INTO THE PLAINS. MODEL CONSENSUS INDICATES SPLIT
FLOW PATTERN WILL KEEP PRIMARY UPPER LOW TO THE SOUTH THROUGH
THURSDAY BEFORE IT DRIFTS SOUTH BEYOND. THE TROPICAL MOISTURE
FEEDING INTO THE PLAINS WILL KEEP EFFICIENT RAIN MAKERS IN THE
PICTURE AS RFC 3HR FFG THROUGH EVENING INDICATES AROUND A HALF
INCH OF RAIN REQUIRED FOR ADDITIONAL FLOODING OVER MUCH OF
SOUTHWEST NEBRASKA ESPECIALLY IN CHASE...HAYES...PERKINS...KEITH
AND LINCOLN COUNTIES. RAINFALL REPORTS FROM CHASE COUNTY INDICATE
OVER 11 INCHES OF RAIN HAS FALLEN IN THE CHAMPION AREA.

THIS MORNING FLOODING CONCERNS LINGER WITH DRIER AIR POSSIBLY
WORKING INTO THE FAR SOUTHWEST THAT WOULD CUT DOWN ON RAINFALL
POTENTIAL. FURTHER NORTHEAST INCREASING CONVERGENCE ALONG THE
SURFACE BOUNDARY WILL ENHANCE RAINFALL POTENTIAL TODAY. MODELS ARE
GENERATING MORE THAN ENOUGH RAIN WITH THE SLOW BREAKDOWN IN THE
BLOCKING PATTERN FOR AREAS EAST OF 83 TO GET RAIN THURSDAY AS THE
DEFORMATION ZONE SHIFTS EASTWARD SLOWLY. THURSDAY THE SPLIT FLOW
PATTERN BECOMES MORE ESTABLISHED WITH THE UPPER CLOSED LOW TO
DRIFT SOUTH ACROSS OKLAHOMA. THE SURFACE FRONT WILL THEN BECOME
LESS DEFINE AND WASHOUT AS CONVERGENCE ALONG THE BOUNDARY WANS
WITH THE APPROACH OF THE NEXT BOUNDARY FROM THE NORTHWEST.

FRIDAY THROUGH SATURDAY THE UPPER RIDGE BUILDS ACROSS THE WEST
WITH TEMPERATURES REBOUNDING INTO THE 90S FOR THE START OF THE
WEEKEND. GUIDANCE NUMBERS MAY BE TOO WARM FRIDAY GIVEN THE MASS OF
WATER WOES EXCEPT FOR THE FAR NORTHWEST INTO THE PANHANDLE.

FOR THE LONG TERM SUNDAY THROUGH MONDAY FEW CHANGES MADE A RIDGE
BREAKS DOWN AND UPPER TROUGH DEVELOPS ACROSS THE WEST THAT WILL
LEAD TO TIMING ISSUES WITH WAVES LIFTING OUT TO ENHANCE LIFT FOR
STORM DEVELOPMENT INTO THE START OF THE NEW WORKWEEK.

&&

.AVIATION...
PERIODS OF HEAVY RAIN...SHOWERS AND THUNDERSTORMS WILL CONTINUE
TODAY ALONG THE ERN PTNS OF TWB ROUTES 098...274 AND 264. VFR AND
MVFR CONDITIONS ARE EXPECTED ON THE WRN PTNS OF THOSE ROUTES. FLIGHT
CONDITIONS WILL GENERALLY IMPROVE WEST TO EAST TODAY BUT THE DRIER
AIR AND IMPROVED FLIGHT CONDITIONS ARE EXPECTED TO MOVE ONLY VERY
SLOWLY EAST.
