REMAIN HIGH BETWEEN 1-1.5 INCHES.  DEPENDING ON THE
CLOUDCOVER...THERE IS THE POTENTIAL FOR INSTABILITY TO INCREASE TO
1000-2500J/KG AND LI/S AROUND -4 TO -8.  DEEP LAYER SHEAR IS AROUND
25 TO 30KTS.  AHEAD OF THE COLD FRONT WILL MAINTAIN CHANCE FOR
SHOWERS AND THUNDERSTORMS.  SEVERE STORMS WILL BE CONDITIONAL ON
HEATING TODAY.  SPC HAS A MARGINAL RISK FOR SEVERE STORMS...WITH THE
SLIGHT RISK NOSING IN TOWARD JEFFERSON COUNTY.  THE DEVELOPMENT OF
THUNDERSTORMS IS PROBLEMATIC TOO IN REGARD TO HEAVY RAIN.  UNTIL WE
SIGNIFICANTLY DRY OUT...STORMS THAT FORM IN THE MOIST AIR WILL BE
CAPABLE TO PRODUCE LOCALLY HEAVY RAIN.

TONIGHT...THE PROGRESS OF THE COLD FRONT IS SLOW...GENERALLY PUSHING
ACROSS SOUTHEAST NEBRASKA TOWARD FALLS CITY. INCLUDED HIGHER POPS
IN SOUTHEAST NEBRASKA AND SOUTHWEST IOWA WITH SPOTTIER
PRECIPITATION FARTHER NORTH. SOUTHWEST FLOW ALOFT WILL ABOVE THE
SURFACE FRONT AND MOISTURE IN THE AREA WILL KEEP THE SHOWERS AND
THUNDERSTORMS GOING NEAR THE KANSAS AND MISSOURI BORDERS FRIDAY
THROUGH SATURDAY MORNING...HOWEVER DRY AIR AND WEAKER FORCING
SHOULD LIFT THE COVERAGE OF PRECIPITATION FARTHER NORTH. IMPACTS
OF THE APPROACHING TROF SATURDAY AFTERNOON SHOULD INCREASE SHOWERS
AND THUNDERSTORMS ACROSS THE SOUTHWEST TOWARD FAIRBURY.

.LONG TERM...(SATURDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 345 AM CDT THU MAY 7 2015

SATURDAY NIGHT...THE CLOSED H5 LOW MOVES INTO THE WESTERN PLAINS.
THIS SHOULD PRODUCE WIDESPREAD SHOWERS AND THUNDERSTORMS ACROSS
THE AREA WITH THE RAIN LIFTING NORTH AND THE DRY SLOT WORKING INTO
THE SOUTHWEST TOWARD FAIRBURY. THE SURFACE LOW IS FORECAST TO
TRACK FROM SOUTHWEST NEBRASKA TOWARD NORTHEAST NEBRASKA. SEVERE
STORMS WILL BE SOMETHING MONITOR WITH THE TRACK OF THIS STORM.
WRAPAROUND MOISTURE IS PROGGED TO AFFECT NORTHEAST NEBRASKA MONDAY
WITH SOME NEGATIVE H85 TEMPERATURES MONDAY MORNING. STILL PLENTY
OF TIME TO ADD A MIX IF NEEDED.

.AVIATION...(12Z TAFS FOR KOFK...KLNK AND KOMA.)
ISSUED AT 634 AM CDT THU MAY 7 2015

ONLY ISOLATED SHOWERS ARE EXPECTED AT TAF SITES EARLY IN THE TAF
PERIOD. VFR CIGS AT KLNK AND KOMA WILL PREVAIL...WITH MVFR CIGS AT
KOFK THROUGH 18Z. THEN A COLD FRONT DRIFTING SOUTH WILL TURN WINDS
TO THE NORTHWEST BY 22Z AT KOFK...THEN KLNK AND KOMA SHORTLY AFTER
00Z. A FEW THUNDERSTORMS MAY DEVELOP ALONG THIS FRONT...BUT
COVERAGE IS EXPECTED TO BE ISOLATED ENOUGH AT TAF SITE TO PRECLUDE
A MENTION AT THIS TIME.
