DENSE FOG OVER THE SOUTHERN HALF OF THE AREA THIS MORNING WAS
CONSTRAINED TO THE HUMID AIRMASS AHEAD OF THE COLD FRONT. THAT
FOG HAS SINCE DISSIPATED WITH THE MORNING INSOLATION AND
MIXING.
SFC HIGH SETTLES INTO THE AREA TODAY, WITH SUBSIDENCE KEEPING
SKIES MOSTLY CLEAR. THE WIDESPREAD SUNNY SKIES WON'T BE ENOUGH
TO MAKE UP FOR THE SLIGHTLY COOLER AIR IN PLACE TODAY BEHIND
THAT COLD FRONT. HIGH TEMPERATURES WILL RANGE FROM NEAR 80 TO
MID-80S ALONG KANSAS AND SOUTH DAKOTA. NORTHERLY WINDS OF 5-10
MPH WILL BECOME LIGHT AND VARIABLE OVERNIGHT. MODEL GUIDANCE HAS
SOME FOG DEVELOPMENT IN SOUTHERN IOWA AND NORTHWEST MISSOURI
OVERNIGHT WHERE DEWPOINTS WILL REMAIN HIGHER. HAVE ADDED PATCHY
FOG IN OVERNIGHT TO WESTERN IOWA.
THURSDAY
HIGH TEMPS WILL MOSTLY MIRROR THOSE OF TODAY. LIGHT NORTHERLY
WINDS WILL BECOME SOUTHERLY AS RETURN FLOW DEVELOPS IN THE
AFTERNOON/EVENING. MOSTLY CLEAR SKIES PERSIST. IT'LL BE ANOTHER
PLEASANT DAY!
FRIDAY
SOUTHERLY WINDS PICK UP THE PACE (10-15 MPH) AS TEMPS PUSH JUST
ABOVE SEASONAL NORMS. ISOLATED AFTERNOON POPS (10-20%) GROW TO
30-60% NORTH OF THE PLATTE RIVER OVERNIGHT WHEN THE LLJ KICKS
INTO GEAR. HEIGHT FALLS ARE ASSOCIATED WITH A SHORTWAVE PUSHING
THROUGH THE DAKOTAS, INITIATING FORCING FOR ASCENT. MOST WILL
BE DRY, BUT THERE WILL BE LESS SUNSHINE. SHOULD STORMS
MATERIALIZE, THEY MAY BE ABLE TO GROW SEVERE BY TAPPING INTO 2K
J/KG OF CAPE AND SHEAR VALUES NEAR 50 KNOTS.
THE WEEKEND
HIGHS PUSH INTO THE 90S FOR SATURDAY AS TRANSIENT RIDGE PASSES
THROUGH THE HIGH PLAINS. SUNSHINE AND 20 KNOT SOUTHERLY WINDS
SERVE AS WINGMEN.
SUNDAY WILL BE WARMER WITH NEAR RECORD HIGHS. OMAHA CURRENTLY
FORECAST FOR 97. THE STANDING RECORD AT EPPLEY IS 99F SET IN
2013.
NEXT WEEK.
A NEW PATTERN DEVELOPS EARLY NEXT WEEK AS A CUT-OFF LOW WORKS
THROUGH THE PRAIRIE PROVINCES OF CANADA. THIS SHOULD DAMPEN THE
RIDGING AND LEAVE THE CORN BELT UNDER THE INFLUENCE OF
SOUTHWESTERLY FLOW ALOFT. THIS SHOULD RE-ESTABLISH THE BUSY
PATTERN AND BRING BACK THE DAILY CHANCES OF SHOWERS AND
THUNDERSTORMS (20-40%). SIGNALS FOR SIGNIFICANT RAINFALL ARE
BEST BY THE END OF NEXT WEEK... ESPECIALLY IN IOWA.
SUNDAY WILL BE THE HOTTEST DAY OF THE WEEK, BUT NEXT WEEK'S
NUMBERS REMAIN ABOVE EARLY SEPTEMBER NORMS.

WEDNESDAY. SKIES REMAIN MOSTLY CLEAR. THERE IS A LOW CHANCE OF
