AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
354 AM CDT SUN MAY 24 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 350 AM CDT SUN MAY 24 2015

A WARM FRONT WILL LIFT NORTH ACROSS THE REGION TODAY...WITH
SOUTHERLY WINDS AND A WARMER AIRMASS EXPECTED IN ITS WAKE. AS A
RESULT...DESPITE THE CONTINUED CLOUD COVER...EXPECT TEMPERATURES
TO CLIMB SEVERAL DEGREES ABOVE SATURDAYS UNSEASONABLY COOL
READINGS...WITH AFTERNOON HIGH TEMPERATURES TOPPING OUT NEAR 70
ACROSS THE MAJORITY OF THE FORECAST AREA.

OTHER THAN TEMPERATURES...PRECIPITATION CHANCES HAVE PRESENTED
QUITE A CHALLENGE THIS MORNING...AS WHILE PLENTY OF MOISTURE AS
WELL AS SOME MODEST INSTABILITY/SHEAR WILL BE IN PLACE...THE LACK
OF A SIGNIFICANT FORCING MECHANISM COULD HELP KEEP CONVECTIVE
ACTIVITY TO A MINIMUM. DESPITE THIS...THE NORTHWESTERN PORTIONS OF
THE FORECAST AREA REMAINS IN A MARGINAL RISK FOR SEVERE WEATHER
FROM SPC...SO WILL NEED TO MONITOR THIS AREA AS IF SOME CLEARING
AND RAPID WARMING OCCURS...WE COULD SEE A FEW MARGINALLY STRONG TO
NEAR SEVERE STORMS RAPIDLY BUILD DURING THE LATE AFTERNOON
HOURS...ESPECIALLY ACROSS THIS AREA WHERE FORCING FROM A PASSING
SHORTWAVE COULD PROVIDE A SPARK FOR CONVECTION LATER TODAY.

THAT SAID...DESPITE THE FAIRLY MODEST PRECIPITATION CHANCES IN THE
FORECAST FOR MUCH OF THE LOCAL AREA TODAY...DO NOT ANTICIPATE
MUCH IN THE WAY OF OVERALL RAINFALL ACCUMULATION...AS THE LOCAL
AREA SEEMS TO BE POISED BETWEEN BETTER CHANCES WITH THE SHORTWAVE
TO OUR WEST THIS AFTERNOON/EVENING...AND THE FOCUS OF THE LLJ AND
AN ADDITIONAL SHORTWAVE TO OUR EAST TONIGHT. EVEN SO...LIGHT
ACCUMULATIONS WILL BE POSSIBLE THROUGH THE SHORT TERM PERIODS...SO
WHILE CHANCES FOR PRECIPITATION WERE TWEAKED DOWNWARD FOR THE
MOST PART...STILL EXPECT A POTENTIALLY UNSETTLED 24 HOURS WITH LIGHT
RAINFALL ACCUMULATIONS POSSIBLE ALONG WITH LOTS OF CLOUD COVER.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 350 AM CDT SUN MAY 24 2015

UNSETTLED WEATHER WILL CONTINUE TO AFFECT THE AREA THROUGH THE WEEK.
MODELS CONTINUE TO HAVE THE MAIN FEATURES THAT ARE SIMILAR...BUT THE
DETAILS HAVE SOME MINOR DIFFERENCES. THIS PROVES TO BE A CHALLENGE.
EVEN WITH CHANCES FOR SHOWERS AND THUNDERSTORMS NEARLY EVERY
PERIOD...IT WILL NOT BE RAINING ALL OF THE TIME.

THE FIRST UPPER LEVEL LOW MOVES THROUGH THE AREA MONDAY. EXPECT
PRECIPITATION ACROSS THE AREA MUCH OF THE DAY. BY MONDAY NIGHT THE
WAVE MOVES TO THE EAST AND EXPECT PRECIPITATION TO BE GRADUALLY
ENDING. THERE COULD BE A LITTLE THAT LINGERS INTO TUESDAY IN THE
SOUTH AND EAST. A SURFACE HIGH PRESSURE SETTLES INTO THE AREA
TUESDAY AFTERNOON AND TUESDAY NIGHT AND EXPECT DRY CONDITIONS FOR
TUESDAY NIGHT.

THE NEXT UPPER WAVE STARTS TO MOVE IN WEDNESDAY AFTERNOON. THE
MORNING COULD BE DRY...BUT WITH THE WAVE MOVING INTO THE AREA IN THE
AFTERNOON THUNDERSTORMS FROM THE HIGH PLAINS ARE EXPECTED TO MOVE
INTO THE AREA. THE WAVE SHOULD MOVE THROUGH THE AREA WEDNESDAY
NIGHT. FROM WEDNESDAY NIGHT THROUGH SATURDAY AN UPPER LEVEL WAVE
MOVES GRADUALLY THROUGH THE PLAINS. WILL KEEP FAIRLY DECENT CHANCES
FOR PRECIPITATION AS THE WAVE MOVES THROUGH THE AREA. THE MAIN
TROUGH IS THROUGH THE AREA ON SATURDAY.

&&

.AVIATION...(FOR THE 06Z KGRI/KEAR TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1230 AM CDT SUN MAY 24 2015

IFR TO LIFR CIGS ARE EXPECTED TO PERSIST ACROSS THE TERMINALS
OVERNIGHT AS PLENTY OF LOW LEVEL STRATUS WILL CONTINUE TO STREAM
ACROSS THE REGION. MAY EVEN SEE SOME MVFR OR IFR VSBYS DEVELOP IN
AREAS OF BR/-DZ...BUT OPTED TO STICK TO THE OPTIMISTIC SIDE OF
GUIDANCE UNTIL MORE WIDESPREAD BR IS ACTUALLY OBSERVED.
OTHERWISE...CIGS ARE EXPECTED TO LIFT SOME DURING THEY DAY ON
SUNDAY AS THE WINDS SHIFT AND BECOME MORE SOUTHERLY...BUT STILL
REMAIN MVFR THROUGH THE END OF THE PERIOD WITH A SHRA OR EVEN TSRA
POSSIBLE DURING THE LATER HALF OF THE PERIOD.
