MAIN CONCERN WILL REVOLVE AROUND HOW WELL MODELS HANDLE CONVECTIVE
EVENTS TODAY AND TONIGHT...THEN TEMPERATURES AS UPPER RIDGE
REBUILDS ACROSS THE PLAINS REGION.

LAST EVENINGS CONVECTIVE COMPLEX ABOUT TO PUSH EAST OF THE CWA AT
08Z WITH STRONGEST CLUSTER OVER SOUTHWEST IOWA AND EXTREME
SOUTHEAST NEBRASKA. 06Z RAP DOWNPLAYS CONVECTION FOR THE MORNING
PERIOD COMPARED TO NAM OR GFS WITH LATTER MODELS FOCUSING ON A
COMPLEX COMING OUT OF SOUTH DAKOTA. PLAN TO FOLLOW THE RAP TREND
THIS MORNING UNLESS NEW DEVELOPMENT INTENSIFIES TO THE WEST...WITH
POPS INCREASING DURING THE AFTERNOON AND TONIGHT. SOME SMALL
CHANCE OF MAINLY OVERNIGHT CONVECTION SUNDAY NIGHT INTO EARLY
MONDAY BUT WARM MID LEVELS AND STRONGER FLOW TO THE NORTHWEST
AHEAD OF A DEEP UPPER TROUGH WILL HINDER DEVELOPMENT.

CLOUDS AND PERIODS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
HOLD TEMPERATURES DOWN TODAY. WARMER TEMPS RETURN FOR SUNDAY AND
MONDAY ALTHOUGH WITH NO SURFACE FRONT IN THE AREA WILL BE LIMITED
TO THE LOWER 90S FOR MOST AREAS.

.LONG TERM...(MONDAY NIGHT THROUGH FRIDAY)
ISSUED AT 208 AM CDT SAT JUL 25 2015

NEXT COLD FRONT EXPECTED TO COME INTO THE AREA TUESDAY INTO
TUESDAY NIGHT WITH A BETTER CHANCE OF STORMS FOR THE AREA
ASSOCIATED WITH THE FRONT. SOUTH PARTS OF THE AREA COULD SEE
HOT TEMPERATURES AGAIN IN ADVANCE OF THE FRONT ON TUESDAY.
SOME LINGERING PRECIP IN THE FAR SOUTH ON WEDNESDAY BEFORE FRONT
PUSHES FURTHER SOUTH. DEEP UPPER LOW MOVING ACROSS CANADA WILL DIG
A TROUGH IN THE EAST AND RETROGRADE UPPER HIGH CENTER BACK TO THE
SOUTHWEST PART OF THE NATION WEDNESDAY NIGHT THROUGH FRIDAY WITH
SEASONAL TEMPERATURES EXPECTED DURING THAT TIME.
