.UPDATE...
THE SYNOPSIS...NEAR TERM AND SHORT TERM SECTIONS HAVE BEEN UPDATED BELOW.

&&

.SYNOPSIS...
ISSUED AT 234 PM EDT SUN JUN 23 2013

OCCASIONAL UPPER LEVEL WEATHER DISTURBANCES MAY AFFECT THE AREA INTO
THE MIDDLE OF WEEK. A COLD FRONT IS EXPECTED TO MOVE THROUGH AROUND
THURSDAY OR FRIDAY. IN THE WAKE OF THIS FRONT...HIGH PRESSURE WILL
BUILD INTO THE AREA BY NEXT WEEKEND.

&&

.NEAR TERM /REST OF THIS AFTERNOON AND TONIGHT/...
ISSUED AT 234 PM EDT SUN JUN 23 2013

SCATTERED CONVECTION EXPECTED TO CONTINUE FOR THE REST OF THE
AFTERNOON ASSOCIATED WITH A WEAK UPPER LOW...MODERATELY UNSTABLE AIR
MASS...AND LITTLE CAP. MOST OF THE ACTIVITY SHOULD DIMINISH AFTER
SUNSET...HOWEVER THERE IS POTENTIAL FOR ADDITIONAL CONVECTION LATER
TONIGHT AS A REMNANT MVC FROM DISSIPATING COMPLEX OVER EASTERN
IOWA/MISSOURI MOVES INTO THE AREA. FOR THAT REASON...WILL KEEP
CHANCE POPS GOING THROUGHOUT THE TONIGHT PERIOD. HEAVY RAIN IS
POSSIBLE WITH PRECIPITABLE WATERS AROUND 1.75 INCHES.

GFS MOS LOWS TONIGHT LOOK REASONABLE BASED ON LOW LEVEL THICKNESSES.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
ISSUED AT 234 PM EDT SUN JUN 23 2013

MODEL DATA SUGGEST THE LOCAL AREA WILL REMAIN ON THE PERIPHERY OF AN
UPPER RIDGE THAT WILL GRADUALLY SHIFT WESTWARD TOWARDS THE SOUTHERN
ROCKIES BY THE MIDDLE OF THE WEEK. THIS WILL GRADUALLY VEER THE
UPPER FLOW TO A MORE NORTHWEST DIRECTION WITH TIME...BUT LITTLE IN
THE WAY OF LOWERING HEIGHTS/THICKNESSES EXPECTED DURING THIS PERIOD.
AS A RESULT...THERE WILL BE A CONTINUED THREAT FOR POTENTIAL MCS
ACTIVITY INTO THE MIDDLE OF THE WEEK AS STEEPER LAPSE RATES ADVECT
INTO THE AREA. MODEL DATA SEEM TO SUGGEST THE BEST THREAT FOR
CONVECTION WILL BE ON MONDAY AND WEDNESDAY...HOWEVER CONFIDENCE IN
LOCATION AND TIMING OF THESE POTENTIAL SYSTEMS AT THIS POINT IS LOW.
FOR NOW...WILL BROADBRUSH CHANCE POPS ALL PERIODS.

BASED ON PROGGED LOW LEVEL THICKNESSES...THE GFS MOS TEMPERATURE
GUIDANCE LOOKS PRETTY GOOD...SO WILL NOT STRAY TOO MUCH FROM THEM.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...

ISSUED AT 219 PM EDT SUN JUN 23 2013

ECMWF AND GFS DEPICT A WARM AND MOIST PATTERN CONTINUING THROUGH
THE WORK WEEK BEFORE A COLD FRONT AND AREA OF HIGH PRESSURE

CONTINUE CHANCES FOR TSRA THROUGH SATURDAY AS THIS PATTERN
PERSISTS. A RIDGE OF HIGH PRESSURE AND A SURFACE HIGH PRESSURE
BUILDS ACROSS THE AREA ON SATURDAY NIGHT AND SUNDAY...FINALLY
BRINGING THE PRECIP CHANCES TO AND END AS LESS HUMID AIR ARRIVES ON
NORTHERLY WINDS.
