WESELY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
645 PM CDT MON APR 8 2013

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 415 PM CDT MON APR 8 2013

PRIMARY FORECAST CONCERNS LIE WITH INCREASING PRECIPITATION
CHANCES...AND PRECIPITATION TYPE.

SATELLITE IMAGERY SHOWING THE STORM SYSTEM OF INTEREST CURRENTLY
SPINNING OVER THE WRN UT/AZ BORDER...LEAVING SOUTHWESTERLY FLOW IN
PLACE ACROSS THE CENTRAL PLAINS. INCREASED LIFT OUT AHEAD OF THE
SYSTEM HAS ALREADY RESULTED IN THUNDERSTORM DEVELOPMENT OFF TO THE
WEST OF THE CWA...WITH DRY CONDITIONS CURRENTLY IN PLACE OVER THE
CWA. CLOUD COVER HAS BEEN VARIABLE THROUGH THE DAY...AND AFTER
STARTING THE DAY WITH WIDESPREAD LOW LEVEL STRATUS AND AREAS OF
FOG...THE NORTHERN HALF OF THE CWA AT LEAST SAW SOME SUN...THE SRN
HALF DIDNT FARE AS WELL WITH THAT STRATUS LINGERING
AROUND...KEEPING TEMPERATURES IN THE LOWER 60S VS MID 60S/NEAR 70
FURTHER NORTH.

THE SHORT TERM PERIOD WILL BE DOMINATED BY THE UPPER LEVEL LOW TO
THE WEST...WHICH BY 12Z TUESDAY IS EXPECTED TO ONLY HAVE SHIFTED
IN  THE FOUR CORNERS REGION...AND BY EVENING IS STILL WELL TO THE
WEST OF THE CWA...SET UP OVER COLORADO. LOOKING AT
TONIGHT...STRONG/SEVERE THUNDERSTORMS STILL A CONCERN...EVEN WITH
THE CLOUD COVER THROUGH THE DAY STILL SEEING DECENT AMOUNTS OF
INSTABILITY IN PLACE AS DEWPOINTS HAVE REACHED INTO THE 50S/60S. A
COUPLE OF SFC BOUNDARIES ACROSS THE CWA WILL BE WORTH KEEPING AN
EYE ON...A STATIONARY FRONT DRAPED ACROSS THE NRN CWA...AND A
BOUNDARY CAUSED BY THE HEATING DIFFERENCES ACROSS NC KS...WHERE
TEMPS VARY FROM THE LOW 60S TO LOW 70S. MODELS CONTINUE TO SHOW
ACTIVITY PICKING UP ACROSS THE CWA THIS EVENING/TONIGHT...AIDED BY
INCREASED LIFT VIA A 40-50KT LLJ NOSING INTO THE AREA FROM THE
SOUTH. IN ADDITION TO ACTIVITY DEVELOPING OVER/NEAR THE CWA...WILL
HAVE TO WATCH THE ACTIVITY ONGOING TO THE WEST...AND ITS EASTWARD
PROGRESSION TOWARD/THROUGH THE CWA. WOULD THINK WITH THE
BOUNDARIES IN THE AREA AND THE WAA/MOISTURE ADVECTION VIA THE
JET...THAT THIS ACTIVITY COULD MAKE IT THIS FAR EAST.

INTO TOMORROW...WHILE INSTABILITY /BOTH LOW LEVEL AND ELEVATED/
LINGERS IN THE AREA BUT DOES START TO PUSH OFF TO THE EAST THROUGH
THE DAY AS THE COLD FRONT AND COLD AIR PUSH MOVE IN. MODELS
REMAIN IN DECENT AGREEMENT WITH THE TIMING OF THE FRONT...BY 12Z
HAVING STARTING MOVING INTO NWRN PORTIONS OF THE CWA. BY MID
AFTERNOON...THE FRONT IS EXPECTED TO HAVE MOVED THROUGH MOST OF
THE CWA...WITH GUSTY NORTHWEST WINDS BUILDING IN BEHIND. KEPT THE
FALLING TEMPERATURES GOING THROUGH THE DAY...HIGHS FOR THE
MAJORITY OF THE CWA WILL BE MET IN THE MORNING. INHERITED WX GRIDS
OF THUNDER/RAIN TRANSITIONING OVER TO SLEET/FZRA AS COLDER AIR
BUILDING IN THE LOWER LEVELS...WITH FORECAST SOUNDINGS CONTINUING
TO SHOW A WARM NOSE IN THE MID LEVELS...AND SAW NO REASON TO MAKE
ANY SIGNIFICANT CHANGES TO THAT LINE OF THINKING. DEBATED A WINTER
WX ADV FOR AT LEAST NORTHWESTERN SECTIONS OF THE CWA TOMORROW FOR
A COMBO OF THE WINTRY PRECIP AND WINDS...BUT THERE CONTINUES TO BE
ENOUGH VARIATION BETWEEN MODELS THAT CONFIDENCE IN THE AMOUNT OF
SLEET/FZRA IS NOT VERY HIGH...BUT MENTION REMAINS IN THE HWO MID
SHIFT CREW WILL HAVE TO CONSIDER IT...DEPENDING ON HOW THIS
EVENING/OVERNIGHT ACTIVITY PANS OUT. LATE IN THE AFTERNOON...UNTIL
THE FRONT CLEARS THE CWA...CANT RULE OUT THUNDERSTORM
CHANCES...AND IF THINGS SLOW DOWN AT ALL...STRONG/SEVERE
THUNDERSTORMS WILL AGAIN BE A POSSIBILITY...THOUGH THE BETTER
CHANCES SHOULD BE TO THE E/SE OF THE CWA.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 415 PM CDT MON APR 8 2013

WINTRY WEATHER CONDITIONS WILL RETURN THROUGH MID WEEK AS AN
UPPER LOW PRESSURE SYSTEM CURRENTLY IN THE SOUTH CENTRAL ROCKIES
LIFTS NORTHEAST ACROSS THE CENTRAL PLAINS. MODELS ARE FAIRLY
CONSISTENT WITH THE TRACK OF THE SYSTEM WITH THE UPPER LOW
ORIENTED IN COLORADO 00Z WEDNESDAY...WITH THE SYSTEM MOVING INTO
NEBRASKA DURING THE DAY WEDNESDAY. MODELS BEGIN TO DIVERGE WITH
THE TRACK OF THE SYSTEM WEDNESDAY NIGHT WITH THE LOW EITHER
LIFTING NORTHEAST TOWARDS SIOUX FALLS OR DEVELOPING A SECONDARY
LOW CIRCULATION FARTHER SOUTH TOWARDS THE KANSAS CITY AREA.

BASED ON THE CURRENT TRACK...THE SFC COLD FRONTAL BOUNDARY WILL
PRETTY MUCH BE THROUGH OUR CWA BY 00 WED...WITH THE H85 FRONT
STILL  ALONG OUR EAST/SOUTHEAST ZONES. ELEVATED INSTABILITY
REMAINS PRESENT FOR A FEW HOURS IN THE EVENING AND HAVE MAINTAINED
A TSTM MENTION FOR IN OUR SE CWA EARLY TUESDAY EVENING.
OTHERWISE...WE ARE GENERALLY LOOKING AT MAINLY WINTRY WEATHER PCPN
EVENT AS COLD AIR SETTLES IN AT THE SFC WHILE A RATHER DEEP
WARM/ABOVE FREEZING LAYER IS PRESENT AROUND H8. WITH DENDRITIC
MOISTURE LACKING AND PRESENCE OF WARM LAYER MID LAYER ABOVE THE
COLD SFC/LLVL TEMPS BELOW FREEZING...WE ARE LOOKING AT THE
POTENTIAL FOR SEVERAL HOURS OF SLEET/FREEZING RAIN...UNTIL
DENDRITIC MOISTURE ARRIVES AND UPPER LOW MOVES IN. UNCERTAINTY
REMAINS ON HOW MUCH FREEZING RAIN OR SLEET WILL ACTUALLY
ACCUMULATE...BUT CANNOT RULE OUT SOME LIGHT ICING WITH THE
FREEZING RAIN ALONG WITH SOME LIGHT SLEET ACCUMULATIONS.

THE MIXED PCPN WILL GRADUALLY TRANSITION TO SNOW TUESDAY NIGHT OR
EARLY WEDNESDAY MORNING...WITH INTERMITTENT SNOW CONTINUING
THROUGH WEDNESDAY NIGHT BUT THIS WILL ULTIMATELY BE DEPENDENT ON
THE TRACK OF THE UPPER LOW...AS A FARTHER NORTHEAST TRACK WILL
LIMIT SNOW AMOUNTS AND A FARTHER SOUTH TRACK WILL PROVIDE MORE
POTENTIAL FOR ACCUMULATING SNOWFALL. NATIONAL GUIDANCE SUGGESTS AN
INCH OR SO POSSIBLE FOR OUR FAR NORTHERN ZONES FOR STORM TOTAL
SNOWFALL...WHEREAS SPC SNOW PLUMES FROM SREF SUGGESTS HIGHER
AMOUNTS FARTHER SOUTH WITH SEVERAL INCHES POSSIBLE. GIVEN
UNCERTAINTY FOR THIS TIME FRAME WILL MAINTAIN SOME LIGHT SNOW
ACCUMULATIONS FOR MOST LOCATIONS AND THIS WILL NEED TO BE TWEAKED
WITH TIME AS SYSTEM ARRIVES.

WINDS WILL BE ANOTHER CONCERN IN A TIGHT PRESSURE GRADIENT
FOLLOWING  FROPA WITH SFC LOW TO THE EAST AND A 1035MB SFC RIDGE
NOSING INTO THE ROCKIES. THE GREATER PRESSURE RISES TUESDAY
EVENING ARE FCST ACROSS KS AND BREEZY/WINDY CONDITIONS ARE
EXPECTED TUESDAY NIGHT AND ALSO AGAIN ON WEDNESDAY IN THE TIGHT
GRADIENT.

FLURRIES REMAIN IN OUR EASTERN ZONES FOR THURSDAY ON THE BACK SIDE
OF THE LOW...WITH THE FORECAST DRYING OUT FOR THURSDAY NIGHT.

MINIMAL CHANGES WERE MADE TO THE INIT FOR THE EXTENDED PORTION OF
THE FORECAST. TEMPERATURES REMAIN WELL BELOW NORMAL THROUGH MUCH
OF  THE WEEK AND WILL MAKE A RUN TOWARD SEASONAL NORMALS OVER THE
WEEKEND. CONFIDENCE IS NOT HIGH ON PCPN SATURDAY NIGHT...BUT
WEATHER PATTERN DOES APPEAR TO TURN MORE ACTIVE TOWARD THE END OF
THE WEEKEND AND EARLY NEXT WEEK AS AN UPPER LOW CROSSES THE
NORTHERN PLAINS WITH ASSOCIATED SFC BOUNDARY ACROSS THE CENTRAL
PLAINS.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY EVENING)
ISSUED AT 645 PM CDT MON APR 8 2013

DETERIORATING CONDITIONS ARE EXPECTED AT KGRI OVER THE NEXT 24
HOURS AS A STRONG COLD FRONT CROSSES THE TERMINAL. AHEAD OF THIS
FRONT...EXPECT VFR CIGS FOR THE NEXT FEW HOURS...BEFORE SOME
THUNDERSTORMS DEVELOP AND CIGS FALL CLOSER TO MVFR LEVELS.
THUNDERSTORMS ARE THEN EXPECTED TO INCREASE IN COVERAGE AND
INTENSITY DURING THE OVERNIGHT HOURS...BUT DUE TO UNCERTAINTY IN
TIMING AT THE TERMINAL...KEPT IN THE CIGS AND VSBYS IN THE MVFR
RANGE. WINDS WILL ALSO BE ON THE INCREASE OVERNIGHT...INCREASING
OUT OF THE NORTH TO 22G28KT BY 09/12Z. EXPECT THE COLD FRONT TO
CROSS THE TERMINAL ABOUT THIS TIME...AND FOR ANY THUNDERSTORMS TO
TRANSITION TO LIGHT RAIN OR POSSIBLY EVEN A WINTRY MIX OF
PRECIP...WITH IFR CIGS BEHIND THE FRONT.
