AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
400 PM CDT THU JUN 19 2008

.DISCUSSION...
ONGOING SEVERE THUNDERSTORMS AND THUNDERSTORMS CHANCES THROUGH THE
PERIOD WILL BE THE FORECAST CONCERNS THIS FORECAST PACKAGE.

OF NOTE ON THE UPPER AIR CHARTS WERE TGE EMBEDDED SHORTWAVE TROFS
IN THE NW FLOW. LATEST SPC MESOANALYSIS AND RUC SOUNDINGS SHOW
LITTLE IN THE WAY OF CONVECTIVE INHIBITION WITH STEEP LOW LEVEL
LAPSE RATES. SFC BASED CAPE VALUES AT 20Z WERE AROUND 1500 TO 3000
J/KG. SHORTWAVE TROF ENERGY CONTINUES TO PASS ACROSS THE REGION
INTO THE EVENING HOURS AND WITH SUFFICIENT MOISTURE SCT TSRA WITH
SOME SEVERE THUNDERSTORMS EXPECTED TO CONTINUE INTO THE EVENING
HOURS AND THERE COULD BE SOME ISOLATED STORMS LATER TONIGHT.

THE PATTERN CONTINUES FOR FRIDAY...ALTHOUGH LOWER MOISTURE IS
AVAILABLE...ADDED LOW POPS FOR FRIDAY AFTERNOON AND CHANCE POPS
FRIDAY NIGHT. SATURDAY AFTERNOON...YET ANOTHER SHORTWAVE IN THE NW
FLOW WILL BRING A CHANCE FOR CONVECTION...THUS ADDED TO SATURDAY
AFTERNOON AND SATURDAY EVENING PERIOD. SUNDAY STILL LOOKS LIKE
HIGH PRESSURE WILL USHER IN DRY CONDITIONS. HIGHS FRIDAY THROUGH
SUNDAY SHOULD REMAIN IN THE 80S.

IN THE LONG TERM...STARTING SUNDAY NIGHT...THE MEAN MID
TROPOSPHERIC PATTERN HAS A RIDGE AROUND 105 WEST LONGITUDE AND A
TROF OVR THE GRTLKS AND OH/TN REGIO. SFC HIGH PRES HAS EAST OR
SOUTHEAST FLOW. ALTHOUGH THE RIDGE PATTERN REMAINS IN PLACE...DURING
THE DAY MONDAY...THE MID LEVEL RIDGE BEGINS TO BREAKS DOWN
TEMPORARILY WITH A TROF MOVING ACRS THE ROCKIES. THE CONVECTION
APPEARS TO BE TIED CLOSER TO THE SFC FRONT AND UPSLOPE FLOW AROUND
THE SFC HIGH OVER THE WESTERN PLAINS. THE ECWMF IS MORE
PROGRESSIVE WITH THE FRONT INTO THE FCST AREA MONDAY INTO MONDAY
NIGHT AND TUESDAY. MEANWHILE...THE GFS HOLDS OFF THE CONVECTION IN
OUR AREA WITH MCS ACRS THE NRN PLNS AND ACRS KS. HPC USED A BLEND
OF THESE MODELS ALONG WITH NCEP ENSEMBLES.

MONDAY THERE APPEARS TO BE A BETTER CHANCE OF TSRA TO THE WEST OF
THE FCST AREA...HOWEVER...SOME OF THE STORMS MAY MAKE IT FARTHER
EAST...SO BROUGHT IN LOW POPS INTO THE CWA. INCREASED CHC OF TSRA
MONDAY NIGHT INTO TUESDAY WITH THE PASSAGE OF THE MID LEVEL TROF.
THE SFC FNT IN THE VICINITY MAY BE ENOUGH TO LEAVE LOW POPS IN FOR
TUESDAY NIGHT. SINCE THE RIDGE IS NOT BROKEN DOWN ENOUGH THE FRONT
WILL NOT BE PUSHED FAR TO THE SOUTH...THE SFC FNT LINGERS IN KS/MO
AND BEGINS TO PUSH BACK THURSDAY...THUS THESE POPS MAY NEED TO BE
INCREASED.

&&

.AVIATION...
FOR TAF SITES KOMA...KLNK AND KOFK...THROUGH 20/18Z.

SCATTERED THUNDERSTORMS ARE POSSIBLE THROUGH THE EARLY EVENING. OUTSIDE
OF MVFR/IFR CIGS/VSBYS HAIL AND GUSTY WINDS IN THUNDERSTORMS...VFR
CONDITIONS SHOULD PREVAIL THROUGH FRIDAY NOON.
