AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
1220 PM CDT THU MAY 3 2012

.AVIATION...18Z KGRI TAF. IFR CEILINGS TO CONTINUE THROUGH
19Z...WITH VFR CONDITIONS EXPECTED THEREAFTER AS STRATUS
DISSIPATES ACROSS THE AREA. SURFACE WINDS WILL REMAIN LIGHT AND
VARIABLE FOR THE MOST PART BEFORE BECOMING MORE ESTABLISHED FROM
THE SOUTH/SOUTHEAST BY 14Z FRIDAY. SIGNIFICANT VISIBILITY
RESTRICTIONS ARE NOT ANTICIPATED THROUGH THE NEXT 24 HOURS.

&&

.PREV DISCUSSION... /ISSUED 1032 AM CDT THU MAY 3 2012/

UPDATE...MORNING SURFACE ANALYSIS INDICATES AN AREA OF LOW
PRESSURE OVER CENTRAL KANSAS...WITH AN INVERTED TROUGH/EFFECTIVE
DRY LINE EXTENDING NORTH FROM THE LOW INTO NORTH CENTRAL KANSAS AND
SOUTH CENTRAL NEBRASKA. AS OF 15Z THIS BOUNDARY WAS NOTED
EXTENDING FROM NEAR KK82...TO KHSI AND KGRI...TO KOLU. LOW LEVEL
MOISTURE FLUX...ALONG WITH WEAK THERMAL ADVECTION AND RESULTANT
ISENTROPIC UPGLIDE AND SATURATION...HAS RESULTED IN STRATUS
DEVELOPMENT ACROSS THE SOUTHEASTERN ONE-HALF OF THE CWA THIS
MORNING. VISIBLE SATELLITE IMAGERY ALSO INDICATES WEAK CONVECTIVE
DEVELOPMENT WITHIN THIS STRATUS FIELD...BUT THIS CONVECTIVE
ACTIVITY REMAINS VERY WEAK WITH KUEX INDICATING NOTHING IN THE WAY
OF PRECIPITATION ACROSS THE AREA. WENT AHEAD AND TWEAKED SKY GRIDS
TO BETTER REFLECT CURRENT CEILINGS WHICH HAVE OVERTAKEN THE AREA.
12Z NAM AND 06Z OPERATIONAL GFS ALSO SHOW THESE LOW CLOUDS WITH
FORECAST CROSS SECTIONS FROM BOTH MODELS SUGGESTING THIS STRATUS
DECK SHOULD BREAK APART EARLY THIS AFTERNOON AS DIABATIC HEATING
PROMOTES INCREASING CONVECTIVE DEVELOPMENT. A WEAK CU FIELD SHOULD
RESULT BY EARLY TO MID AFTERNOON FOR LOCATIONS NEAR AND SOUTHEAST
OF THE SURFACE BOUNDARY...MUCH LIKE YESTERDAY WITHIN THE PLUME OF
INCREASED LOW LEVEL MOISTURE. A LOW LEVEL INVERSION SHOULD KEEP
DEEP CONVECTION AT BAY THROUGH MUCH OF THE AFTERNOON...BUT AGAIN
LIKE YESTERDAY...DIABATIC HEATING ALONG WITH INCREASED LOW LEVEL
CONVERGENCE AND RESULTANT FORCING ALONG THE SURFACE BOUNDARY...COULD
RESULT IN ISOLATED BUT ROBUST CONVECTIVE ACTIVITY BY LATE
AFTERNOON...WITH THE GREATEST THREAT FOR AFTERNOON SEVERE WEATHER
LIKELY RELEGATED TO OUR EAST/SOUTHEAST...AGAIN WITHIN THE PLUME OF
INCREASED LOW LEVEL MOISTURE.

PREV DISCUSSION... /ISSUED 408 AM CDT THU MAY 3 2012/

THE GFS SUGGESTS AT LEAST 4500 J/KG OF SURFACE CAPE ESPECIALLY
ACROSS THE THE SOUTHEAST PORTION OF THE FORECAST AREA. STILL SOME
CONCERN FOR SEVERE WEATHER POTENTIAL DURING THE AFTERNOON AND
EVENING HOURS TODAY.

FOR THE REMAINDER OF THE SHORT TERM PERIOD...UPPER LEVEL SHORT WAVE

THURSDAY NIGHT AND LINGERING THROUGH SATURDAY NIGHT.

LONG TERM...SUNDAY THROUGH WEDNESDAY.

AN UPPER LEVEL TROUGH WILL BEGIN TO PUSH EASTWARD ACROSS THE
WESTERN HALF OF THE CONUS. BOTH THE GFS AND THE ECMWF SUGGEST A
PORTION OF ENERGY FROM THE TROUGH WILL BREAK OFF IN THE FORM OF A
CLOSED LOW AND REMAIN ACROSS THE SOUTHWEST PORTION OF THE CONUS BY
MONDAY. THE MAIN SURFACE TROUGH WILL PUSH NORTHEAST WARD ACROSS
WYOMING AND THE DAKOTAS. AT THE SURFACE...A LOW PRESSURE SYSTEM
WILL BECOME VERTICALLY STACKED WITH THE UPPER LEVEL LOW AND PUSH A
COLD FRONTAL BOUNDARY THROUGH THE CENTRAL PLAINS BY SUNDAY
AFTERNOON.
