AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
157 PM CDT FRI AUG 8 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 353 AM CDT FRI AUG 8 2014

THE MODEL CONSENSUS AND THE RAP MODEL INDICATE THE ONGOING MCS
WILL DRIFT EAST TODAY AND REACTIVATE THIS AFTERNOON. THIS PLACES
THE BETTER RAIN CHANCES ACROSS THE NCNTL ZONES NORTH OF
INTERSTATE 80. THERE ARE INDICATIONS OF DIURNAL INSTABILITY IN
THE PANHANDLE AND SWRN NEB THIS AFTERNOON...ESPECIALLY GIVEN THE
5 PERCENT SEVERE WEATHER OUTLOOK SPC SUGGESTED. UPPER LEVEL
SUPPORT IN THIS AREA LOOKS VERY WEAK TO NON-EXISTENT. THE RAP
MODEL MAINTAINS BETTER FORCING FARTHER EAST ACROSS THE NCNTL
ZONES WITH THE LEFT FRONT PORTION OF 500 TO 300 MB WIND MAX
POSITIONED THERE.

THE FORECAST USES 50 PERCENT OF THE RAP AND 50 PERCENT OF THE
OTHER MODELS FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS
TODAY WHICH BECOME ISOLATED TONIGHT.

HIGHS TODAY RANGE FROM THE MID 80S SOUTH TO UPPER 70S NORTH WITH
HIGH HUMIDITY.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 353 AM CDT FRI AUG 8 2014

ACTIVE PERIOD CONTINUES DURING THE LONG TERM FORECAST...HOWEVER
MODELS HAVE NOT BEEN VERY GOOD WITH TIMING/PLACEMENT OF UPPER
LEVEL DISTURBANCES WHICH LEADS TO A LOW CONFIDENCE FORECAST.

UPPER LEVEL PATTERN ON SATURDAY SEES AN ELONGATE AND SHALLOW
RIDGE ACROSS THE SOUTHERN PLAINS...WITH A TROUGH ACROSS THE
NORTHERN ROCKIES. AFTER SOME LINGER SHOWERS PUSH EAST IN THE
MORNING...A BRIEF BREAK IN ACTIVITY IS EXPECTED DURING THE DAY.
SOME SUN WILL HELP TO WARM TEMPS INTO THE 80S...THEN MODELS BRING
A FAIRLY STRONG DISTURBANCE ACROSS THE AREA. MODELS IN AGREEMENT
WITH THE WAVE MOVING ACROSS THE ROCKIES DURING THE DAY WITH
THUNDERSTORM DEVELOPMENT ACROSS THE WEST FOR THE AFTERNOON. THE
ACTIVITY SHOULD PUSH EAST OVERNIGHT. SOUTHERLY WINDS AHEAD OF THE
WAVE WILL HELP MOISTEN/SUSTAIN MOISTURE IN THE LOWER LEVELS...AND
THUNDERSTORMS LOOK LIKELY...HOWEVER WILL CAP POPS AT 50 PERCENT
DO TO RECENT COVERAGE OF ACTIVITY WITH THE STRONGER WAVES.

THE WAVE WILL EXIT SUNDAY MORNING WITH A WEAK COLD FRONT TO PUSH
ACROSS THE AREA LATER IN THE DAY. MOISTURE REMAINS AVAILABLE AND
ANOTHER ROUND OF STORMS WILL BE POSSIBLE.

BY MONDAY THE RIDGE BEGINS TO REBUILD ACROSS THE ROCKIES. THIS
WILL SET UP NORTHWEST FLOW ACROSS THE HIGH PLAINS. TYPICAL SUMMER
TIME PATTERN WITH PERIODIC CLIPPERS TO RIDE ON THE PERIPHERY OF
THE RIDGE. WILL HAVE TO MONITOR TIMING...HOWEVER FORECAST FAVORS
A TYPICAL DIURNAL PATTERN OF AFTERNOON THUNDERSTORM DEVELOPMENT
IN THE WEST THEN MOVING EAST IN THE EVENING. TEMPS EARLY IN THE
WEEK SHOULD HOLD IN THE 80S WITH LOWS AROUND 60.

BY MID WEEK THE RIDGE BEGINS TO BREAK DOWN AND SLIDE EAST AS A
TROUGH DEVELOPS ACROSS THE PAC NW. TEMPS SHOULD SEE AN UPWARD
TREND...WITH SOME HIGHS INTO THE LOWER 90S ACROSS THE SOUTHWEST.
PERIODIC UPPER LEVEL DISTURBANCES WILL CONTINUE THE NEED FOR AT
LEAST SOME LOW POPS.

ISSUED AT 151 PM CDT FRI AUG 8 2014

THE CENTER OF AN UPPER LEVEL LOW PRESSURE SYSTEM WILL SLOWLY TRACK
ACROSS SOUTHERN SOUTH DAKOTA THIS AFTERNOON AND EVENING.
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS MOST OF
