Hail and Damaging Winds in Nebraska, June 15, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
305 PM CDT THU JUN 15 2006

.SHORT TERM...EARLY ON...WINDS WILL REMAIN A PROBLEM. SEE NO REASON
TO BRING DOWN THE WIND ADVISORY NOW. WINDS STRUGGLING JUST A BIT WITH
SOME MIXING ISSUES DUE TO CLOUDS...BUT AN INCREASE IN H850 WINDS
AROUND 00Z SHOULD PROVIDE THAT EARLY EVENING TIME FRAME WITH THE
JUICE TO BE IN A LOW END WIND ADVISORY RANGE.

AT LAST MINUTE...HAVE INCLUDE ISOLATED/SCATTERED THUNDERSTORMS THIS
EVENING DUE TO DEVELOPING HIGH BASED CONVECTION NEAR GOODLAND.
40+ DEGREE DEWPOINT DEPRESSIONS FAVOR VERY LITTLE RAIN...AND
EXPECTED COVERAGE TO BE SPARSE. STRONG GUSTY WINDS WILL DRY
LOW LEVELS THE STORY.

THUNDERSTORMS LOOK LESS LIKELY TONIGHT...ESPECIALLY EARLY ON DUE
TO WARM MID LEVEL TEMPERATURES CAPPING THINGS OFF A BIT...AND
CLOUDS LIMITING WARMING. WEAK SURFACE BOUNDARY TO THE WEST OF THE
CWFA SHOWING SIGNS OF RETREATING...AND INITIALLY STORMS SHOULD
FIRE TO THE WEST. EXPECT THUNDERSTORMS TO ROLL NORTHEAST AT
FIRST...BUT GRADUALLY SHIFT EAST OVERNIGHT. KEPT THE HIGHEST
POPS IN THE NORTHWEST. SEVERE WEATHER LOOKS LIMITED TO LOCALIZED
WIND GUSTS.

FRIDAY COULD BE MORE ACTIVE...DEPENDING UPON JUST WHAT WE ARE
DEALING WITH IN THE MORNING. UPPER LOW IS A PRETTY GOOD SYSTEM
AND MOISTURE SHOULD BE A BIT BETTER. SHEAR LOOKS SUPPORTIVE AS
AS DOES A FAVORABLE JET STRUCTURE. NAM IS MUCH SLOWER AND FURTHER
WEST DURING THE DAY...AND THIS MAY IMPACT TEMPERATURES. AT ANY
RATE...LOOKS LIKE A GOOD BET FOR RAIN OVER MUCH OF THE CWFA...
AND PROBABLY A PERIOD OF SEVERE WEATHER...AND THUNDERSTORMS
ORGANIZE INTO A LINE AND POTENTIALLY STRONG WIND EVENT.

.LONG TERM...12Z SATURDAY THROUGH FRIDAY. PRIMARY FORECAST CHALLENGE
WAS IN REFINING PRECIPITATION OPPORTUNITIES AT THE BEGINNING AND
TOWARDS THE END OF THE FORECAST PERIOD.

AFTER A FEW STRONGLY CONSISTENT MODEL RUNS...CONFIDENCE IN FORECAST
FOR FIRST HALF OF THE PERIOD IS RATHER HIGH. HOWEVER...HAVE AVERAGE
CONFIDENCE AT BEST IN SECOND HALF OF PERIOD...ONCE AGAIN DUE TO
MODEL FLUCTUATIONS. OPERATIONAL MODELS AND VAST MAJORITY OF
ENSEMBLES SEEM TO HAVE A GOOD HOLD IN CUTTING OFF THE
SHORTWAVE...AND CLEARING THE CWFA TO THE SOUTH AND EAST BY EARLY
SUNDAY MORNING...WITH COLD FROPA BY MIDDAY SUNDAY. TAKING THE LEAD OF
THE GFS...UK AND GGEM...HAVE TONED DOWN POPS DRASTICALLY AFTER
SUNDAY MORNING. EXPECTATION IS THAT SKY COVER WILL DECREASE QUICKLY
SUNDAY AFTN ON THE BACKSIDE OF THE FRONT. WHOLEHEARTEDLY AGREE WITH
THE THINKING OF THE PREVIOUS SHIFT THAT COOLING BEHIND THE FRONT WILL
BE MEAGER AT BEST...AND GRIDS REFLECT AS SUCH.

NEXT WEEK HAS THE POTENTIAL TO BE QUITE WARM...ESP THE LATTER HALF.
RIDGE BEGINS BUILDING FROM CENTRAL AND SOUTHERN ROCKIES. H85 TEMPS
IN THE MID TO UPPER 20S CELSIUS ON WED/THU. BUMPED TEMPS A BIT BOTH
DAYS...WITH THE VERY REAL POSSIBILITY THAT THEY MAY HAVE TO GO
HIGHER IN THE COMING SHIFTS.

PINNING PRECIPITATION DOWN IN THE EXTENDED HAS BEEN A BIT MORE
DIFFICULT THAN I HAD ANTICIPATED. CURRENT THINKING (OF THE 12Z
OPERATIONAL GFS AT LEAST) HAS SFC FRNTL BNDRY REMAINING N OF THE
AREA...WITH CLOUD COVER AND PRECIP REMAINING NORTH INTO
THE N PLAINS. PREVIOUS MODEL RUNS HAD FAVORED A MORE COPIOUS AND
EXTENDED PERIOD OF RAINFALL. FOR NOW...HAVE CHOSEN TO ERR ON THE
SIDE OF CAUTION AND SIDE WITH DRIER PATTERN RECOGNITION OVER MODEL
SOLUTIONS...WITH THE IDEA THAT DAYS 6-7 BE MONITORED FOR MORE
CONSISTENT MODEL OUTPUT.
