NWS Quad Cities, IA wrote its last area forecast discussion before the first event at Jun 26, 6:29 AM CST, 2 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 729 AM CDT FRI JUN 26 2015 .SYNOPSIS... ISSUED AT 325 AM CDT FRI JUN 26 2015 SEVERE MCS IS MOVING SOUTHEAST ACROSS EXTREME EASTERN KS AND WESTERN MO BUT WAS MOVING SOUTHEAST WHERE THE HIGHER CAPE AND MOISTURE WAS LOCATED. TO THE NORTH OF THE BOWING LINE THERE WAS AN AREA OF STRATIFORM RAIN AND A FEW EMBEDDED LIGHTNING STRIKES IN EXTREME SOUTHERN IA AND THIS WAS SPREADING EASTWARD. IN THE MEANTIME...SCATTERED SHOWERS WERE LOCATED IN NORTHERN IA BUT THE LOW LEVELS WERE QUITE DRY AND MOST OF THIS WAS ALOFT. A COUPLE OF OBSERVATIONS SITES DID HAVE 10SM -RA. THIS WAS AHEAD OF AN UPPER LEVEL TROUGH DIVING SOUTHEAST OUT OF THE DAKOTAS. ON THE WEATHER MAP...A NEARLY STATIONARY EAST-WEST FRONTAL BOUNDARY EXTENDED FROM SW KS TO CENTRAL MO AND TO VA. THE NOCTURNAL LOW LEVEL JET WAS VEERED INTO MO. HIGH PRESSURE WAS LOCATED IN THE NORTHERN GREAT LAKES REGION. 3 AM TEMPERATURES IN THE DVN CWA RANGED FROM 60 AT FREEPORT TO 70 AT KEOKUK. READINGS WERE IN THE COOL 40S AROUND THE NORTHERN GREAT LAKES REGION ASSOCIATED WITH THE CANADIAN HIGH. && .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 325 AM CDT FRI JUN 26 2015 FORECAST FOCUS ON SHOWERS AND A FEW THUNDERSTORMS TODAY BUT THEN DRY AND COOLER TONIGHT. TODAY...OPERATIONAL MODELS TAKE THE NORTHERN FRINGES OF THE MO MCS ACROSS OUR FAR SOUTHERN COUNTIES THIS MORNING. HOWEVER...CONSIDERING THIS IS STRATIFORM TYPE PRECIPITATION THE MODELS SEEM TO BE OVERDOING THE QPF. THE HEAVY RAIN IS TIED TO THE SEVERE MCS WELL TO OUR SOUTH WHERE PWATS ARE 2 INCHES. THERE MAY BE A FEW EMBEDDED LIGHTNING STRIKES BUT FOR THE MOST PART THIS IS LIGHT TO MODERATE RAIN. IN THE NORTHERN CWA...FORECAST SOUNDINGS INDICATE THE LOW LEVELS ARE QUITE DRY UNTIL LATER THIS MORNING AND AFTERNOON WHEN MOISTENING OCCURS. THEREFORE I WILL HAVE CHANCE POPS FOR A TIME THIS MORNING THEN GO WITH SCATTERED SHOWERS. ASSUMING SOME BREAKS IN THE OVERCAST THERE MAY BE JUST ENOUGH INSTABILITY TO HAVE ISOLATED WEAK THUNDERSTORMS THIS AFTERNOON (SBCAPES WILL BE ABOUT 500 J/KG). THESE SHOWERS WILL BE GENERATED BY A DEEPENING UPPER LEVEL TROUGH DIVING SOUTHEAST OUT OF THE DAKOTAS. TEMPERATURES WILL BE HELD IN CHECK DUE TO PLENTY OF CLOUDS AND A NORTHEAST WIND. AFTERNOON HIGHS WILL BE IN THE MID 70S. THIS IS ROUGLY 10 DEGREES BELOW NORMAL FOR LATE JUNE. TONIGHT...AS THE UPPER LEVEL TROUGH DIGS STRONGLY INTO THE OHIO VALLEY SUBSIDENCE IN IT'S WAKE WILL BRING CLEARING SKIES AND DRIER AIR INTO THE DVN CWA...ON NORTHERLY WINDS. ANY LINGERING SHOWERS WILL END THIS EVENING. THIS UPPER LEVEL PATTERN LOOKS ALMOST FALL-LIKE WITH A DEEP TROUGH IN THE EAST AND A BIG RIDGE IN THE WEST. TIME TO OPEN THE WINDOWS AS MINIMUM TEMPERATURES DROP INTO THE 50S. .LONG TERM...(SATURDAY THROUGH THURSDAY) ISSUED AT 325 AM CDT FRI JUN 26 2015 ACTIVE NORTHWEST FLOW ALOFT TO DOMINATE THROUGH THE PERIOD WITH PERIODIC RAIN CHANCES AND NEAR TO BELOW NORMAL TEMPS. SATURDAY...LOOKS TO BE BEST DAY OF THE WEEKEND BY FAR WITH WEAK HIGH PRESSURE IN CONTROL PROVIDING AMPLE SUNSHINE AND COMFORTABLE HUMIDITY LEVELS WITH AID OF DRYING ON NORTHERLY WINDS. HIGHS SHOULD GENERALLY BE IN THE UPPER 70S TO AROUND 80. SUNDAY...GENERAL CONSENSUS ON SUNDAY BEING UNSETTLED/WET WITH THE PASSAGE OF AN UPPER LEVEL DISTURBANCE AND ATTENDANT SURFACE COLD FRONT. THE AMOUNT OF HEATING/DESTABILIZATION AND MOISTURE RECOVERY WILL LOOM LARGE IN DETERMINING THE POTENTIAL FOR ANY STRONG TO POSSIBLY SEVERE STORMS DURING THE AFTERNOON. MONDAY THROUGH FRIDAY...STAGNANT HIGH AMPLITUDE UPPER PATTERN TO FEATURE WESTERN RIDGE /HEAT DOME/ AND EASTERN TROUGH. THE END RESULT FOR OUR CWA IS A CONTINUATION OF ACTIVE NORTHWEST FLOW FOR MOST IF NOT ALL OF NEXT WEEK. WHILE THIS WILL SPELL PERIODIC RAIN CHANCES THERE WILL BE A LOT OF DRY TIME AS WELL. TRYING TO PIN DOWN THE MORE FAVORABLE PERIODS FOR RAIN CHANCES IS THE MAIN CHALLENGE GIVEN MODEL DIFFERENCES WITH TIMING OF WEAK DISTURBANCES IN NORTHWEST FLOW LARGELY ATTRIBUTED TO POOR RESOLUTION OF THESE LOW AMPLITUDE WAVES. BLANKETING THE LONG TERM WITH RAIN CHANCES IS THE UNFORTUNATE BY-PRODUCT OF SUCH A DILEMMA... BUT AGAIN DO ANTICIPATE THERE TO BE MANY DRY HOURS. AS FOR TEMPS GENERALLY EXPECT PERSISTENCE WITH HIGHS MAINLY IN THE 70S/NEAR 80 AND LOWS IN THE 50S/60S. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SATURDAY MORNING) ISSUED AT 728 AM CDT FRI JUN 26 2015 OCNL MVFR/IFR CIGS THIS MORNING IN SHOWERS AND FOG THEN VFR CIGS IN SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS THIS AFTERNOON. CLEARING TONIGHT AS HIGH PRESSURE BUILDS INTO THE AREA. NORTHEAST WINDS AROUND 10 KNOTS TODAY THEN NORTH LESS THAN 10 KNOTS TONIGHT. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE. IL...NONE.
