AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
337 AM CDT THU JUN 17 2010

.DISCUSSION...
UPPER LOW HAS NOT MADE TOO MUCH PROGRESS THROUGH PAC NW THE PAST 24
HOURS AND ON H5 ANALYSIS WAS LOCATED OVER EASTERN OREGON AS OPPOSED
TO WESTERN WASHINGTON 24 HOURS AGO. BEST HGHT FALLS TO THE
SOUTH/EAST OF THE SYSTEM WHICH LOOKS TO MOVE THE LOW MORE EASTWARD
INTO WYOMING THIS MORNING BEFORE LIFTING NORTHEAST TO NEAR THE
NDAKT/SASK BORDER OVER THE NEXT 24 HOURS OR SO. AT SFC...06Z
ANALYSIS HAS PAIR OF LOWS OVER HIGH PLAINS...ONE OVER SE
MONTANA...THE OTHER NEAR THE COMMON BORDER OF WY/CO/NE. THIS HAD
PULLED LLVL MOISTURE AXIS BACK INTO CENTRAL/NORTHERN PANHANDLE AHEAD
OF AN APPROACHING FRONT. ASCENT OVER THIS FRONT/MOISTURE SOURCE
SEEMED TO KICK OFF ROUND OF TSRA WHICH IS MOVING THROUGH THE BLACK
HILLS ATTM. 88D MOSAIC SEEMS TO BE SHOWING THE FRONT BEGINNING TO
ACCELERATE THROUGH FAR SOUTHEAST CORNER OF WYOMING. THE FRONT SHOULD
CONTINUE TO TRACK EASTWARD THROUGH CWA TODAY AS THE UPPER LOW
ROTATES INTO EASTERN MT. STRONG WESTERLIES ROTATING AROUND THE
SOUTHERN PERIPHERY OF THE LOW LOOK TO MIX DOWN ALONG STEEPING LOW
LEVEL LAPSE RATES THROUGH THE MID TO LATE MORNING. STRONGEST
DOWNSLOPE WINDS LOOKS TO AFFECT AREAS OFF THE FRONT RANGE OF ROCKIES
INTO FAR NW NEB...BUT BUFKIT/GUIDANCE SEEM TO BE LEANING TOWARD ADV
WINDS FOR NW PORTION OF CWA WITH MOMEMTUM XFER SHOWING GUST
POTENTIAL NEAR 50 MPH IN FAR NW CORNER. WILL ISSUE ADVY FOR THIS
MORNING THROUGH THE LATE AFTERNOON HOURS. DRY WESTERLY FLOW BEHIND
FROPA SHOULD KEEP THREAT OF PCPN OFF TO THE EAST OF THE CWA.
SOUTHERN ADVANCEMENT OF THE FRONT LOOKS TO GET HUNG UP ACOSS WC KS
INTO SOUTHEAST NEB AND AS SOUTHERLY JET FIRES AGAIN TONIGHT ELEVATED
CONVECTION LOOKS POSSIBLE NORTH OF FRONT ACROSS SOUTH CENTRAL AND
SOUTHEAST NEB SO PLAN TO KEEP FCST DRY ATTM. NEXT CHANCE FOR PCPN
LOOKS TO BE FRIDAY NIGHT AS THERE LOOKS TO BE A COLISION OF FRONTS
ACROSS SOUTHERN NEB WITH 50KT PLUS LLVL JET ONCE AGAIN PROVIDING THE
EXTRA LIFT NECESSARY FOR LATE NIGHT CONVECTION. ONE FRONT WILL BE
FORCED SOUTHWARD BY THE NORTHERN PLAINS UPPER LOW MOVING OFF TOWARD
THE WESTERN GREAT LAKES WHILE INCREASING LLVL WAA ACROSS SW HIGH
PLAINS LOOKS TO FORCE COLD FRONT BACK NORTHWARD INTO NORTHERN KS AS
A WARM FRONT. THIS FRONT SHOULD THEN SETTLE BACK INTO NORTHERN KS ON
SATURDAY LEAVING MAINLY A QUIET AND SLIGHTLY COOLER DAY WITH LATE
AFTERNOON CONVECTION MOST LIKELY TO START IN FAVORED POST FRONT
AREAS OF NORTHEAST COLORADO AND THE CHEYENNE RIDGE. THIS SHOULD
TRACK EASTWARD THROUGH THE NIGHT AND THE CHANCE POPS INTO SUNDAY
MORNING LOOK ON TRACK. FOR THE NEXT FEW DAYS...BC MOS AND COOLER
GUIDANCE DID WELL FOR TEMPS ON TUESDAY AND PLAN TO LEAN THAT WAY THE
NEXT FEW DAYS WITH TEMPS GENERALLY IN THE UPPER 70S TO LOWER 80S
NORTH...80S SOUTH.

WEST.
