AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
644 PM CDT TUE JUL 14 2015

.SYNOPSIS...
ISSUED AT 327 PM CDT TUE JUL 14 2015

UPPER LEVEL SYNOPTIC FLOW BEEN RATHER STEADY STATE OVER THE PAST
SEVERAL DAYS WITH A STRONG RIDGE OF HIGH PRESSURE CENTERED OVER THE
SOUTHERN PLAINS...WITH TROUGHS OVER THE PACIFIC COAST AND EASTERN
CONUS. SEVERAL WEAK MID TO UPPER LEVEL PERTURBATIONS EMBEDDED WITHIN
THE ANTICYCLONIC FLOW HAVE BEGUN TO SLOWLY SUPPRESS THE STRENGTH OF
THE RIDGE FROM THE INTERMOUNTAIN WEST INTO THE HIGH PLAINS...HOWEVER
HOT CONDITIONS PERSIST FOR MUCH OF THE CENTRAL CONUS. CLOSER TO THE
CWA MID TO UPPER LEVEL CLOUD COVER HAS BEEN SLOWER THAN ORIGINALLY
FORECAST. AS A TEMPERATURES ARE RUNNING A FEW DEGREES WARMER THAN
SUGGESTED BY MORNING FORECAST GUIDANCE...GENERALLY IN THE LOW TO
UPPER 90S.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 327 PM CDT TUE JUL 14 2015

WEAK MID-LEVEL PV ANOMALY APPROACHES FROM SOUTHWEST LATER THIS
AFTERNOON AND EVENING. THE INCREASING DCVA ALOFT WILL HELP
SPARK ISOLATED TO SCATTERED THUNDERSTORM DEVELOPMENT FROM THE HIGH
PLAINS INTO WESTERN NEBRASKA. IN ADDITION TO CONVECTION ALREADY
DEVELOPING AND MOVING OFF THE FRONT RANGE...HI-RES MODELS HAVE
FAVORED THE NOSE OF THE STEEPEST LOW LEVEL LAPSE RATES IN NORTHEAST
COLORADO/NORTHWEST KANSAS/SOUTHWEST NEBRASKA FOR INITIAL CONVECTIVE
DEVELOPMENT THEN SLOWLY TRACK THE CONVECTION NORTHEAST. ALTHOUGH
SHEAR IS MEAGER...MLCAPE AOA 1000 J/KG AND INVERTED-V SOUNDING
PROFILES WILL PROMOTE THE POTENTIAL FOR STRONG WIND GUSTS THROUGH
THE EVENING. LOW LEVEL SOUTHERLY FLOW JUST OFF THE SURFACE INCREASES
AFTER DARK. WAA/ISENTROPIC ASCENT NORTH OF A DEVELOPING SFC LOW AND
WARM FRONT IN WESTERN KANSAS WILL HELP GENERATE AND SUSTAIN MORE
WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY OVERNIGHT. THE OVERALL
SEVERE THREAT DECREASES AS CONDITIONS BECOME MORE STABLE. HOWEVER
INCREASING PWATS ASSOCIATED WITH A SURGE OF MID TO UPPER LEVEL
MONSOONAL MOISTURE FROM THE SOUTHWEST...ALONG WITH SLOW STORM
MOTIONS...SUGGEST THE THREAT FOR LOCALLY HEAVY RAINFALL OVERNIGHT.

SYNOPTIC PATTERN ALOFT REMAINS RELATIVELY UNCHANGED FOR WEDNESDAY
WITH A STATIONARY RIDGE AXIS UP THE PLAINS STATES. UPSLOPE FLOW
BECOMES ESTABLISHED OVER THE CWA AS AN AREA OF SURFACE LOW PRESSURE
CONTINUES TO SLOWLY DEEPEN OVER WESTERN KS WITH AN ATTENDANT WARM
FRONT STRETCHING ACROSS NORTHERN KANSAS TO NEAR THE NEBRASKA BORDER.
NORTH OF THE FRONT NORTHEASTERLY SURFACE FLOW WILL ADVECT DEEPER
MOISTURE BACK INTO THE CWA...WITH MID TO UPPER 60S DEWPOINTS LIKELY
FOR MUCH OF THE AREA BY THE AFTERNOON. A BRIEF LULL IN THUNDERSTORM
ACTIVITY IS EXPECTED AS THE OVERNIGHT/EARLY MORNING CONVECTION
PUSHES EAST. MID TO UPPER LEVEL MOISTURE TAP FROM THE SOUTHWEST
KEEPS UPPER LEVEL CLOUD COVER IN PLACE AND LIMITS HIGHS TEMPS TO 10F
OR SO COOLER THAN TODAY. HOWEVER THE POOLING OF RICH LOW LEVEL
THETA-E AIR IMMEDIATELY NORTH OF THE WARM FRONT SHOULD STILL
SUFFICIENTLY DESTABILIZE THE ATMOSPHERE AND PROMOTE THE DEVELOPMENT
OF ADDITIONAL SHOWERS AND STORMS BY THE AFTERNOON AND INTO THE
EVENING HOURS. THE MOST FAVORABLE AREA FOR CONVECTIVE INITIATION
WILL BE FROM SOUTHWEST INTO CENTRAL NEBRASKA WHERE STRONG TO SEVERE
STORMS WILL BE POSSIBLE. MODEL SOUNDINGS SUGGEST STRONG LOW-LEVEL
VEERING WIND PROFILES IN ADDITION TO 35-40 KTS OF DEEP LAYER SHEAR.
DAMAGING WINDS AND LARGE HAIL WILL BE THE PRIMARY THREATS. AT THIS
TIME THE TORNADO THREAT LOOKS TO STAY JUST SOUTH AND EAST OF THE CWA
WHERE LOW LEVEL HELICITY VALUES WILL BE MAXIMIZED IN THE VICINITY OF
THE WARM FRONT. THE NORTHWARD PROGRESSION OF THE WARM FRONT WILL
NEED TO BE CLOSELY MONITORED...AS WELL AS THE POSITION OF ANY
REMNANT OUTFLOW BOUNDARIES FROM EARLY DAY CONVECTION.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 327 PM CDT TUE JUL 14 2015

00Z THURSDAY AND BEYOND.  ALOFT...BROAD UPPER LEVEL RIDGE WILL
EXTEND NORTH ACROSS THE CORNBELT WHILE A TROUGH OF LOW PRESSURE
EXTENDS SOUTH ACROSS THE WESTERN STATES.  A SECOND TROUGH WILL
RESIDE OVER THE NORTHEASTERN SEABOARD...WITH CLOSED LOW PRESSURES
NOTED NORTHEAST OF HUDSON BAY...OVER NORTHERN BRITISH COLUMBIA...AND
CENTERED OVER THE CENTRAL ALEUTIANS.

A SHORTWAVE WILL HELP TO SUPPRESS THE RIDGE TEMPORARILY TO THE SOUTH
OF THE FORECAST AREA LATE WEDNESDAY NIGHT AND EARLY
THURSDAY...HOWEVER TEMPERATURES WILL WARM ALOFT ONCE AGAIN BEHIND
THE DEPARTING WAVE BY THURSDAY AFTERNOON.  THE WARMING TEMPERATURES
SHOULD HELP LIMIT CONVECTIVE CHANCES THURSDAY...HOWEVER ACROSS NORTH
CENTRAL NEBRASKA A SLIGHT CHANCE REMAINS AS AN ADDITIONAL
DISTURBANCE CROSSES THE NORTHERN PLAINS.  A MODERATE TO STRONGLY
UNSTABLE ATMOSPHERE WILL LIE OVER THE REGION...WITH AMPLE SHEAR FOR
SEVERE STORMS.

FOR THE REMAINDER OF THE EXTENDED...RIDGE AMPLIFIES TO THE EAST OF
THE FORECAST AREA AS A TROUGH OF LOW PRESSURE CLOSES OFF THE PACIFIC
NORTHWEST COAST.  WARM CONDITIONS ARE FORECAST INTO THE WEEKEND.
DAILY THUNDERSTORM CHANCES CANNOT BE RULED OUT AT THIS TIME...AS
OCCASIONAL LOW -AMPLITUDE WAVES COMBINE WITH A WAFFLING NORTH TO
SOUTH FRONT TO BRING ISOLATED STORMS TO THE REGION.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)
ISSUED AT 640 PM CDT TUE JUL 14 2015

ISOLATED TO SCATTERED THUNDERSTORM COVERAGE IS EXPECTED OVERNIGHT
THROUGH WEDNESDAY AFTN. THIS ACTIVITY IS ASSOCIATED WITH
INCREASING LOW LEVEL MOISTURE AND AN UPPER LEVEL DISTURBANCE
ACROSS THE COLORADO ROCKIES CARRYING SUBTROPICAL MOISTURE.

THE SREF SUGGESTS THE POTENTIAL FOR MVFR CIGS WEDNESDAY 15Z-00Z
BETWEEN HIGHWAY 20 AND INTERSTATE 80 ASSOCIATED WITH INCREASING
LOW LEVEL MOISTURE.
