COOLER...BELOW NORMAL HIGHS.

WE`VE HAD A SEVERAL ROUNDS OF PRECIPITATION TODAY WITH THE MAIN AREA
OF HEAVY RAIN PER WSR-88D RADAR SOUTH OF NEBRASKA CITY. AT
20Z...SCATTERED SHOWERS CONTINUED AS FAR BACK AS LOGAN
IOWA...TO OMAHA AND LINCOLN. THE 12Z OAX SOUNDING FROM THIS
MORNING WAS CUT SHORT DUE TO THUNDERSTORM CONTAMINATION.

FROM THE UPPER AIR MAPS...THERE WAS UPPER LEVEL DIVERGENCE WITH THE
RIGHT REAR ENTRANCE REGION OF THE JET AND THIS LIFT CONTINUES WITH A
MAXIMUM SHIFTING INTO MISSUOURI THIS EVENING. THE H5 LEAD TROF
HAS BEEN MOVING THROUGH...WITH THE MAIN H5 TROF STILL OVER
NORTHERN MINNESOTA INTO SOUTH DAKOTA. WATER VAPOR SATELLITE
IMAGERY/LIGHTNING SHOWS MID LEVEL MOISTURE OVER THE PLAINS WITH
THUNDERSTORMS CLUSTERED OVER SOUTHEAST NEBRASKA/SOUTHWEST IOWA
INTO NORTHWEST AND PARTS OF KANSAS. DEWPOINTS WERE STILL IN THE
70S OVER FAR SOUTHEAST NEBRASKA AND SOUTHWEST IOWA...HOWEVER DRIER
60S WERE WORKING IN WITH THE COLD FRONT AND THE BRISK NORTH WINDS.
SMOKE WAS CREATING HAZY CONDITIONS AND REDUCED VISIBILITIES FOR
PARTS OF NORTHEAST NEBRASKA.

THE LATEST SPC MESOANALYSIS HAS THE MAX MLCAPE TO THE SOUTH OF THE
FORECAST AREA...HOWEVER THE 2.2 INCH MAX PWAT IS STILL ACROSS
SOUTHEAST NEBRASKA AND SOUTHWEST IOWA. FORCING IS WEAKER...HOWEVER
THERE IS STILL SOME FORCING ALOFT WITH THE WARM AIR ADVECTION AND
LINGERING H85 AND H7 MOISTURE. WILL CONTINUE TO NUDGE POPS DOWN
DURING THE EVENING AS THE COLD FRONT PUSHES INTO KANSAS AND
MISSOURI. BRISK NORTH WINDS WILL GRADUALLY DECREASE AFTER
MIDNIGHT AND SURFACE HIGH PRESSURE WILL BE BUILDING IN. SOME PATCH
FOG IS POSSIBLE WITH THE WET GROUND AND DECREASING WINDS ALOFT.

SMOKE HAS BEEN REDUCING VISIBILITIES AND OUR COOP OBSERVER IN
BLOOMFIELD CAN NOW SMELL THE SMOKE. THE SMOKE FORECASTS SHOW SMOKE
IN PARTS OF OUR AREA TONIGHT AND TUESDAY. WILL INCLUDE IT IN THE
ZONE FORECAST FOR PARTS OF NORTHEAST NEBRASKA THIS EVENING.
FORECASTERS CAN ASSESS IF THE SMOKE IS THICK ENOUGH TO INCLUDE
TUESDAY.

THE NEXT LONGWAVE TROF TRACKING THROUGH CANADA INTO THE PLAINS
WILL RETURN DEEPER MOISTURE TUESDAY NIGHT AND WEDNESDAY. THE 18Z
NAM IS MORE AGGRESSIVE WITH THE NORTHWARD PROGRESS OF THE
PRECIPITATION AHEAD OF THE FRONT. DO HAVE SOME RAIN CHANCES FOR
FAR SOUTHEAST NEBRASKA AND SOUTHWEST IOWA FOR NOW. SCATTERED
THUNDERSTORMS ARE MENTIONED WITH THE SHORTWAVE ON THURSDAY.

COOLER...BELOW NORMAL HIGHS IN THE 70S ARE FORECAST TUESDAY
THROUGH THURSDAY.

ISSUED AT 1158 PM CDT MON JUL 6 2015

NORTHERLY WINDS WILL CONTINUE TO USHER IN REDUCED VISIBILITIES FROM
CANADIAN HAZE/SMOKE ACROSS THE REGION. MAINLY MVFR CONDITIONS ARE
ANTICIPATED...HOWEVER VISIBILITIES WILL TEMPORARILY DIP INTO IFR
RANGE THROUGHOUT THE NIGHT. FURTHER REDUCTION IN VISIBILITIES COULD
OCCUR AS SMOKE AIDS IN THE DEVELOPMENT OF FOG.  CONFIDENCE REMAINS
LOW AS TO WHEN HAZE/SMOKE WILL FINALLY CLEAR OUT OF THE REGION.  FOR
NOW THINKING CONDITIONS WILL IMPROVE TO VFR LEVELS TUESDAY
AFTERNOON...BUT WILL CONTINUE TO MONITOR AND UPDATE THE FORECAST AS
