AREA FORECAST DISCUSSION...UPDATED AVIATION NATIONAL WEATHER SERVICE ST LOUIS MO 808 PM CDT THU APR 18 2013 .SHORT TERM...(THROUGH LATE TONIGHT) ISSUED AT 317 PM CDT THU APR 18 2013 AT 19Z/2PM...THE SFC CDFNT WAS LOCATED FROM NEAR KPPQ-ENTERING THE WRN SUBURBS OF STL METRO-NEAR KFYG-REYNOLDS COUNTY MO. THIS CDFNT HAS BEEN ACCOMPANIED BY A SUDDEN WIND SHIFT OUT OF THE W AND AN INCREASE IN WINDS TO GUSTS TO 30-35 MPH AS WELL AS A SHARP TEMP DROP INTO THE 40S WITHIN A HOUR OR TWO. A NARROW LINE OF CONVECTION HAS DEVELOPED ALONG THE FRONT BUT THE AIR IT IS MOVING THRU IS VERY WELL WORKED OVER AND DO NOT ANTICIPATE MUCH STRENGTH TO DEVELOP IN THE CONVECTION ALTHOUGH A BRIEF HEAVY DOWNPOUR IS LIKELY. AT THE UPPER LEVELS...A DEEP TROF EXISTS OVER THE PLAINS AND HAS BEEN PROGRESSING SLOWLY NEWD...WITH THE CENTER OF THIS POWERFUL STORM SYSTEM OVER ERN NEBRASKA. ANOTHER SHORTWAVE EXISTS OVER ERN ALBERTA PROVINCE CANADA AND COULD PLAY A ROLE IN OUR WX FOR FRIDAY. THE CENTER OF THE STORM SYSTEM WILL CONTINUE TO PUSH NEWD AND INTO THE UPR MS VALLEY BY LATE THIS EVENING WITH THE TROF AXIS EXTENDING TO THE S NOT MOVING THRU OUR FA UNTIL FRIDAY MORNING. THIS WILL PROMOTE MORE CLOUDS THAN NOT THRU THAT TIME AND WILL GO WITH A MOSTLY CLOUDY FCST ALTHOUGH LOSS OF HEATING THIS EVENING COULD DEVELOP A FEW MORE HOLES IN THE SC CLOUD DECK TO OUR W IN ERN KS. MODELS SEEM TO HAVE A GOOD HANDLE ON EWD PUSH OF RAIN AND TSRA... WITH THE HEAVIER RAIN AND TSRA TO EXIT THE FAR ERN FA...AROUND MARION AND WASHINGTON COUNTIES IN IL...BY THE MIDDLE PART OF THIS EVENING OR AROUND 9PM. WHAT WILL BE IN ITS WAKE WILL BE A PERIOD OF LIGHT RAIN OR DRIZZLE WHICH IN ITSELF SHOULD BE SHORT-LIVED. THIS AREA OF DRIZZLE SHOULD FOLLOW CD FROPA OR WITHIN AN HOUR OR SO. WITH THE EXIT OF THE HEAVIEST RAINFALL RATES ASSOCIATED WITH TSRA BY 23Z/6PM...DO NOT ANTICIPATE EXTENDING THE FFA IN TIME AND WILL LIKELY TAKE A DEEP CUT TO IT BY THE 4PM PACKAGE ISSUANCE. TEMPS ARE QUITE CHILLY BEHIND THE CDFNT...AND COUPLED WITH WIND GUSTS OUT OF THE W AT 25-30MPH...IT WILL FEEL MUCH COLDER IN AREAS COMPARED TO WHAT WE HAD DEALT WITHIN 24HRS PRIOR. MOS MIN TEMPS FOR TONIGHT LOOK REASONABLE DESPITE HIGH LEVELS OF MIXING AND CLOUDS WITH KMCI ALREADY AT 38F EARLY IN THE AFTN! DO NOT SEE THE NEED FOR ANY FROST OR FREEZE HEADLINES WITH MINS AT OR ABOVE 32F EXPECTED AND WINDS TOO HIGH FOR FROST DEVELOPMENT. TES .LONG TERM...(FRIDAY THROUGH NEXT THURSDAY) ISSUED AT 317 PM CDT THU APR 18 2013 FRIDAY AND FRIDAY NIGHT...A NORTHWEST FLOW SHORTWAVE /CURRENTLY OVER ERN ALBERTA AND WRN SASKATCHEWAN/ WILL DIVE SEWD INTO THE MIDWEST IN THE WAKE OF A DEPARTING LOW PRESSURE SYSTEM. THIS FEATURE WILL PROVIDE FORCING FOR SCT SHRA ON FRIDAY ACROSS PARTS OF MO/IL/IA. DESPITE SOME MODEL DISAGREEMENT REGARDING HOW FAR SOUTH AND WEST THIS FEATURE WILL BE LOCATED BY FRIDAY AFTN...THERE IS GENERAL AGREEMENT REGARDING AN AREA OF DIVERGENCE ALOFT ACCOMPANIED BY FAVORABLE H7-H5 LAPSE RATES FOR ISO-SCT SHRA ACROSS EXTREME NERN MO AND WEST CENTRAL IL. RIDGE AXIS THEN BUILDS INTO THE REGION ON FRI NIGHT LEADING TO DECREASING WINDS. SKIES ALSO BEGIN CLEARING ON FRI NIGHT WHICH SHOULD LEAD TO FAIR RADIATIONAL COOLING CONDITIONS CONSIDERING THE DRIER AIR MASS THAT WILL BE IN PLACE BY THAT TIME. HOWEVER...THE VERY MOIST GROUND AND LARGE AREAS OF STANDING WATER FROM RECENT HEAVY RAINFALL WILL PROBABLY MODIFY THAT AIR MASS BY MOISTENING IT AT THE LOWEST LEVELS. DEPENDING ON HOW MUCH MOISTENING OCCURS AND OVER WHAT DEPTH...IT IS POSSIBLE THAT FOG COULD DVLP TOMORROW NIGHT AND INTERFERE WITH THE EXPECTED TEMPERATURE DROP. SATURDAY THROUGH SUNDAY NIGHT...SFC HIGH SHIFTS EWD ALLOWING A RETURN OF SLY TO SWLY WINDS. THE COMBINATION OF WINDS AROUND THE BACK SIDE OF THE HIGH PRESSURE CENTER ALONG WITH WINDS INDUCED BY A DVLPG SFC LOW ON THE LEE SIDE OF THE ROCKIES WILL PULL A WMFNT NEWD INTO MO ON SAT. IT LOOKS LIKE THE WARMEST TEMPERATURES WILL BE ACROSS CENTRAL MO AND THE ERN OZARKS. A BROAD BUT WEAK TROF WILL PASS ACROSS THE AREA ON SUNDAY AND COULD PROVIDE SUPPORT FOR ISO- SCT SHRA HOWEVER THERE IS LOW CONFIDENCE IN PCPN ATTM. MONDAY THROUGH WEDNESDAY...A STRONG LOW PRESSURE SYSTEM IS FCST TO DVLP INVOF THE FOUR CORNERS REGION EARLY NEXT WEEK AND PRODUCE WIDESPREAD PCPN ACROSS MO/IL. THIS SYSTEM WILL ALSO SEND ANOTHER CDFNT ACROSS THE AREA LEADING TO COOLER TEMPERATURES FOR THE MIDDLE OF NEXT WEEK. THERE ARE STILL SOME TIMING AND PLACEMENT DIFFERENCES BETWEEN THE GFS AND THE ECMWF HOWEVER BOTH MODELS ARE IN GENERAL AGREEMENT ON THE LARGE SCALE PATTN. ATTM TUESDAY LOOKS LIKE THE MOST FAVORABLE TIME PD FOR WIDESPREAD PCPN. KANOFSKY && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING) ISSUED AT 740 PM CDT THU APR 18 2013 POTENT COLD FRONT MOVED THRU EARLIER TODAY SWITCHING WINDS TO THE WEST. IT IS CURRENTLY ALIGNED FROM N CNTRL IL THRU SE IL THEN ALONG THE MS RIVER INTO LA. PRECIP ALONG THE FRONT IS SLOWLY MOVING EAST AND SHOULD EXIT S CNTRL IL THIS EVENING. THERE IS PLENTY OF LOW LEVEL MOISTURE ON THE BACKSIDE OF THIS SYSTEM THAT WILL CONTINUE TO MOVE IN FROM THE NW THRU THE FCST. SOME PATCHES OF VERY LIGHT RAIN AND/OR DRIZZLE EXIST ACROSS NE MO AND W CNTRL IL. THIS ACTIVITY IS NOT SIGNIFICANT ENOUGH TO CAUSE ANY ISSUES AT THE TERMINALS AND THEREFORE WAS NOT INCLUDED IN THE FCST. SATELLITE AND SFC OBS SHOW WIDESPREAD MVFR CIGS ACROSS THE ENTIRE MIDWEST. THE MVFR CIGS WILL BE THE RULE OVERNIGHT AND SHOULD GRADUALLY RISE THRU THE DAY FRIDAY. CIGS SHOULD BEGIN TO SCATTER OUT TOWARDS FRIDAY EVENING. AS THE MAIN STORM SYSTEM LIFTS INTO THE GRT LKS...THE PRESSURE GRADIENT WILL INCREASE KEEPING A GUSTY WRLY WIND THRU FRIDAY. SPECIFICS FOR KSTL... MVFR CIGS AND A GUSTY WRLY WIND WILL CONTINUE THRU TONIGHT AND INTO TOMORROW. CIGS AND WINDS SHOULD DIMINISH AFTER SUNSET. 2% && .LSX WATCHES/WARNINGS/ADVISORIES... MO...NONE. IL...NONE. && WFO LSX
