AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
254 PM CDT SUN MAY 8 2016

.SHORT TERM...(TONIGHT THROUGH WEDNESDAY)
ISSUED AT 253 PM CDT SUN MAY 8 2016

12Z UPPER-AIR ANALYSIS AND MORNING WATER VAPOR IMAGERY INDICATE THAT
THE UPPER LOW OVER THE LOWER CO VALLEY IS IN THE PROCESS OF
REFORMING OVER THE CNTRL HIGH PLAINS. MEANWHILE...A MID-LEVEL JET
STREAK AND ASSOCIATED LOW-AMPLITUDE SHORT-WAVE TROUGH OVER THE
CNTRL/SRN HIGH PLAINS WILL TRANSLATE NEWD INTO THE MID MO VALLEY BY
TONIGHT. WHILE THE PRIMARY SURFACE LOW IS FORECAST TO REMAIN OVER
WRN KS TONIGHT...THE INFLUENCE OF THIS LATTER UPPER-AIR FEATURE WILL
PROMOTE THE DEVELOPMENT OF A MESOLOW NNEWD ALONG AN INVERTED TROUGH
THROUGH CNTRL NEB...WITH A WARM FRONT LIFTING NWD THROUGH PORTIONS
OF ERN NE/SWRN IA.

MID-AFTERNOON SURFACE OBSERVATIONS AND OBJECTIVE ANALYSIS INDICATE
THAT CONSIDERABLE LOW-LEVEL MOISTENING AND RESULTANT AIR MASS
DESTABILIZATION IS OCCURRING ACROSS SRN INTO CNTRL NE...INVOF THE
DIFFUSE WARM FRONT. CONVECTION-ALLOWING MODEL GUIDANCE REMAINS
CONSISTENT IN SUGGESTING INITIAL STORM DEVELOPMENT LATER THIS
AFTERNOON ACROSS PORTIONS OF WRN INTO N-CNTRL KS. OTHER STORMS MAY
BEGIN TO DEVELOP BY LATE AFTERNOON INTO EARLY EVENING ALONG A WEAK
INVERTED TROUGH OVER CNTRL NE. THESE DATA SUGGEST THAT THE KANSAS
STORMS MAY GROW UPSCALE INTO AN MCS WITH EMBEDDED BOWING
STRUCTURES WHICH WOULD BEGIN TO IMPACT OUR SOUTHWESTERN COUNTIES
BY 8 TO 9 PM. THESE STORMS ARE THEN EXPECTED TO RAPIDLY SPREAD
NEWD ACROSS THE REMAINDER OF OUR AREA OVERNIGHT. SHOULD THIS
SCENARIO UNFOLD AS FORECAST...THE PRIMARY SEVERE WEATHER HAZARDS
WOULD BE LARGE HAIL AND DAMAGING WIND GUSTS. HOWEVER...A TORNADO
OR TWO IS POSSIBLE WITH ANY MATURE STORMS THAT CAN FAVORABLY
INTERACT WITH THE NWD-MOVING WARM FRONT.

MONDAY AND MONDAY NIGHT...A VORTICITY LOBE AND ASSOCIATED JET STREAK
OVER THE SRN HIGH PLAINS MONDAY MORNING WILL EJECT NEWD THROUGH THE
MID MS VALLEY...CONTRIBUTING TO THE EWD DEVELOPMENT OF THE PARENT
UPPER LOW THROUGH THE MID MO VALLEY INTO MIDWEST. THE PRIMARY
SURFACE LOW WILL GRADUALLY FILL WHILE DEVELOPING FROM WRN INTO NERN
KS. AN INVERTED TROUGH WILL STRETCH FROM THIS CYCLONE NWWD INTO THE
NRN HIGH PLAINS.

WE COULD SEE A TEMPORARY BREAK IN SHOWER AND TSTM ACTIVITY MONDAY
MORNING IN THE WAKE OF THE LEAD SHORT-WAVE TROUGH. HOWEVER...LARGE-
SCALE FORCING FOR ASCENT WILL INTENSIFY BY AFTERNOON...YIELDING
LIKELY SHOWERS AND THUNDERSTORMS BY AFTERNOON INTO THE FIRST PART OF
MONDAY NIGHT...ALONG AND EAST OF THE INVERTED SURFACE TROUGH. SEVERE
WEATHER POTENTIAL MONDAY AFTERNOON AND EVENING WILL BE LARGELY
DICTATED BY THE AMOUNT OF SURFACE HEATING THAT CAN OCCUR. WHILE
VERTICAL SHEAR WILL NOT BE PARTICULARLY STRONG...THE PRESENCE OF
STEEP LAPSE RATES AND A REASONABLY MOIST BOUNDARY LAYER WILL BE
SUPPORTIVE OF SOME SEVERE STORM THREAT ACROSS CNTRL AND SRN PORTIONS
OF THE CWA. LARGE HAIL WILL BE THE PRIMARY HAZARD.

PRECIPITATION CHANCES SHOULD BEGIN TO TAPER OFF LATE MONDAY NIGHT
INTO EARLY TUESDAY AS THE STRONGER FORCING FOR ASCENT SHIFTS EAST
OF THE AREA.

TUESDAY INTO WEDNESDAY...THE AFOREMENTIONED UPPER-AIR SYSTEM
SHIFTING TO OUR EAST WILL UNDERGO RAPID WEAKENING WHILE EJECTING
ACROSS THE GREAT LAKES AHEAD OF AN AMPLIFYING UPSTREAM TROUGH OVER
THE NRN AND CNTRL PLAINS. THIS SYSTEM WILL BE ATTENDED BY A
SURFACE LOW TRACKING ACROSS THE DAKOTAS...AND A TRAILING COLD
FRONT WHICH WILL SWEEP EWD THROUGH THE MID MO VALLEY TUESDAY
NIGHT. WE WILL MAINTAIN SLIGHT CHANCE POPS ACROSS NRN AND CNTRL
COUNTIES TUESDAY...THOUGH THE BEST MEASURABLE PRECIPITATION
POTENTIAL WILL BE TUESDAY NIGHT INTO WEDNESDAY AS THE COLD FRONT
MOVES THROUGH THE AREA.

HIGHS MONDAY AND TUESDAY WILL BE GENERALLY IN THE 70S...COOLING TO
60S BEHIND THE COLD FRONT WEDNESDAY. OVERNIGHT LOWS WILL BE IN THE
50S.

.LONG TERM...(WEDNESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 253 PM CDT SUN MAY 8 2016

THE MID-LEVEL TROUGH OVER THE N-CNTRL U.S. AT THE ONSET OF THE
EXTENDED PERIOD WILL TRANSLATE EWD THROUGH THE GREAT LAKES WITH NWLY
FLOW BECOMING ESTABLISHED FROM THE NRN ROCKIES TO MID MS VALLEY INTO
NEXT WEEKEND. A LOW-AMPLITUDE PERTURBATION TRACKING THROUGH THE
DAKOTAS INTO UPPER GREAT LAKES FRIDAY INTO FRIDAY NIGHT WILL DRIVE A
COLD FRONT THROUGH THE MID MO VALLEY...SUPPORTING SLIGHT CHANCE POPS
ACROSS THE ERN CWA. ANOTHER SHORT-WAVE TROUGH WILL FOLLOW THE TRACK
OF THE FORMER --THROUGH THE DAKOTAS INTO THE UPPER GREAT LAKES-- NEXT
WEEKEND WITH SLIGHT CHANCE TO LOW CHANCE POPS AGAIN WARRANTED.
NEAR NORMAL HIGH TEMPERATURES AROUND MID WEEK ARE EXPECTED TO COOL
TO SLIGHTLY BELOW NORMAL --I.E. LOW TO MID 60S-- LATE NEXT WEEK
INTO NEXT WEEKEND.

.AVIATION...(18Z TAFS FOR KOMA...KLNK...KOFK THROUGH 18Z MONDAY)
ISSUED AT 1243 PM CDT SUN MAY 8 2016

VFR CONDS ARE EXPECTED THROUGH THE AFTN. AN INCREASE IN SCT
SHRA/TSRA ARE EXPECTED THIS EVNG AND WILL LIKELY AFFECT ALL 3 TAF
SITES. HAVE INCLUDED A TEMPO GROUP FOR NEAR THE GREATEST
CONFIDENCE IN TIMING. OTHERWISE A GOOD DEAL OF SHRA ARE EXPECTED
OVERNIGHT. WE WILL LIKELY SEE SOME MVFR CIGS DVLP THIS EVNG WITH
SOME IFR CONDS POSSIBLE AT KLNK/KOFK OVERNIGHT AND INTO MON MRNG.
SOME IMPROVEMENT IN CIG CATEGORY IS EXPECTED BY MID MON MRNG.
