TODAY

REGIONAL RADAR THIS MORNING SHOWING AREA OF ELEVATED CONVECTION
LIFTING NEWD ACROSS THE CWA WITH AREAL COVERAGE GRADUALLY SHRINKING
AND EXPECT THE PCPN ACTIVITY...PER LATEST HRRR...EXITING THE CWA
DURING RUSH HOUR.

MAIN ISSUE TO CONTEND THEN IS TIMING COLD FRONT/TSTM REDEVELOPMENT
THIS AFTN. MSAS CURRENTLY SHOWING THE COLD FRONT HAS ALREADY DROPPED
INTO THE DAKOTAS/UPPER MID WEST WITH PCPN ACTIVITY TRYING TO DEVELOP
ALONG THE LEADING EDGE OF THE BNDRY. HRRR/RAP13 IN AGREEMENT THE
BNDRY WILL BE QUICK IN NATURE AND SHOULD BE CROSSING INTO THE NRN
CWA SHORTLY BEFORE NOON. AS THE FRONT CONTINUES TO MOVE SOUTH EXPECT
CONVECTION TO INTENSIFY LATE THIS AFTN ALONG AXIS OF STEEP 0-3KM
LAPSE RATE. AMPLE MOISTURE WILL BE IN PLACE AS WELL TO THE SOUTH
WITH PWS AROUND 1.5" AND KI VALUES APPROACHING 40.

AS FOR TEMPS...QUITE POSSIBLE THAT THE NRN CWA WILL SEE DAYTIME
HIGHS REACHED BY EARLY AFTN WITH NEAR STEADY TEMPS THEREAFTER.

DEE

TONIGHT THROUGH SUNDAY

COLD FRONT MAY BE VERY NEAR I80 THEN QUICKLY PUSHES SOUTH OF THE
AREA BY 06Z AND BEYOND. WILL MAINTAIN 50 TO 70 PERCENT CHANCE OF
STORMS ALONG THE FRONT...WITH LINGERING SHOWERS ENDING IN THE FAR
SOUTHEASTERN AREA BEFORE 7 AM SATURDAY.

BREEZY CONDITIONS EXPECTED BEHIND THE FRONT THAT LINGERS INTO
SATURDAY MORNING...ALONG WITH MORNING CLOUDS...BUT SKIES QUICKLY
BECOME SUNNY BY SATURDAY AFTERNOON WITH WINDS DIMINISHING.
SOMEWHAT COOL DAY SATURDAY WITH HIGHS IN THE MID TO UPPER 60S.

SUNDAY SHOULD BE A REALLY NICE DAY...ALTHOUGH INCREASING HIGH
CLOUDS COULD OCCUR. WINDS BECOME SOUTHEAST AND TEMPS INCREASE INTO
THE UPPER 60S TO LOWER 70S.



.LONG TERM...(SUNDAY NIGHT THROUGH THURSDAY)
ISSUED AT 333 AM CDT FRI MAY 29 2015

NORTHWEST FLOW ALOFT EARLY IN THE PERIOD MAY ALLOW A WEAK SYSTEM
TO MOVE INTO EASTERN NEBRASKA BY DAYBREAK MONDAY BRINGING A
CHANCE FOR PRECIP. ANOTHER WEAK SYSTEM COULD ALSO AFFECT THE SAME
AREA MONDAY NIGHT...ALTHOUGH IT COULD VERY WELL REMAIN TO THE
NORTH. RAIN CHANCES CONTINUE WEDNESDAY INTO THURSDAY.
