AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
340 AM CDT SAT AUG 29 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 339 AM CDT SAT AUG 29 2015

PATCHY FOG OVER NORTH CENTRAL NEBRASKA AGAIN THIS MORNING. WILL
CARRY THROUGH MID MORNING. HAVE RETAINED PATCHY FOG OVER NORTH
CENTRAL NEBRASKA AGAIN TONIGHT. SOUTHERLY FLOW TODAY AND GOOD
INSOLATION OVER THE WEST WILL SEE TEMPERATURES RISE INTO THE 90S
MOST AREAS AS THE UPPER RIDGE BUILDS INTO THE NORTHERN PLAINS.
MOSTLY CLEAR SKIES AGAIN TONIGHT WITH PATCHY FOG OVER NORTH CENTRAL
NEBRASKA TOWARDS SUNRISE. LIGHT AND VARIABLE WINDS AND TEMPERATURES
RADIATING OUT WITH LOWS IN THE 50S AND 60S.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 339 AM CDT SAT AUG 29 2015

UPPER LEVEL RIDGING WILL BE IN PLACE ACROSS THE CENTRAL PORTIONS OF
THE UNITED STATES THROUGH THE WEEKEND. THE COMBINATION OF STRONG
CAPPING ALOFT AND NO DISCERNIBLE SURFACE BOUNDARIES...SHOULD KEEP
ANY TSTM ACTIVITY AT BAY AND WILL CONTINUE THE DRY FORECAST. ON
SUNDAY LOWERING PRESSURE ALONG THE FRONT RANGE WILL CREATE A
TIGHTENING PRESSURE GRADIENT FROM EAST TO WEST ACROSS THE REGION. AS
A RESULT GUSTY SOUTHERLY WINDS ARE EXPECTED TO DEVELOP. INDICATIONS
ARE THAT 30 MPH GUSTS APPEAR POSSIBLE ACROSS NORTH CENTRAL
NEBRASKA...WITH 25 MPH GUSTS LIKELY ACROSS CENTRAL AND SOUTHWEST
NEBRASKA.

THE FIRST IN A SERIES OF SHORTWAVES ALOFT WILL MOVE THROUGH THE
NORTHERN PLAINS MONDAY INTO MONDAY NIGHT. THIS WILL DRIVE A WEAK
COLD FRONT INTO NORTH CENTRAL THROUGH SOUTHWEST NEBRASKA MONDAY
AFTERNOON AND EVENING. THIS COULD BE THE FOCUS FOR A COUPLE OF
ISOLATED TSTMS...BUT CAPPING ALOFT REMAINS A CONCERN AND WILL NOT GO
BEYOND JUST A SLIGHT CHANCE FOR RAINFALL AT THIS TIME.

AS MENTIONED A SERIES OF SHORTAVES ALOFT WILL MOVE INTO THE PACIFIC
NORTHWEST AND THROUGH THE NORTHERN PLAINS NEXT WEEK. THESE WILL HAVE
LITTLE IMPACT ON OUR WEATHER...WITH WARM SOUTHERLY FLOW MAINTAINING
NEAR TO SOMEWHAT ABOVE NORMAL HIGH TEMPERATURES IN THE UPPER 80S TO
LOWER 90S. BY LATE IN THE WEEK...A MORE SIGNIFICANT SHORTWAVE ALOFT
WILL DRIVE A COLD FRONT INTO THE REGION...AND WITH BETTER UPPER
LEVEL FORCING EXPECT A CHANCE FOR TSTM ACTIVITY TO RETURN.

ABOVE 95 PERCENT AND ONE RAPID REFRESH MODEL SHOWS VISIBILITY AT OR
