AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 234 PM CDT MON JUN 17 2013 .DISCUSSION... ISSUED 220 PM CDT MON JUN 17 2013 SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT MAIN CONCERNS THIS PERIOD WILL BE WITH COVERAGE OF PRECIP ACRS OUR SOUTHERN COUNTIES TONIGHT...ASSOCIATED WITH AN MCV OVER MISSOURI... AND WITH A WEAK SURFACE BOUNDARY FORECAST TO EDGE INTO OUR AREA TUESDAY AFTERNOON. AFTER THAT...SOMEWHAT COOLER AND LESS HUMID WEATHER WILL FOLLOW INTO THURSDAY BEFORE HEAT BUILDS NORTHWARD INTO THE REGION FOR THE END OF THE WEEK AND NEXT WEEKEND. WATER VAPOR LOOP SHOWING THE CONVECTIVE COMPLEX FROM LAST NIGHT PRODUCING A DISTINT MCV OVER PARTS OF WESTERN MO WITH NEW CONVECTION DEVELOPING TO ITS EAST INTO EAST CENTRAL AND SE MO AND TRYING TO DEVELOP A BIT FURTHER NORTH INTO SOUTHERN ILLINOIS. LOOKING NORTH... SEVERAL LOW AMPLITUDE SHORTWAVES TRACKING E-SE ACRS THE NORTHERN PLAINS. ONCE SUCH WAVE PUSHING ACRS WISCONSIN WITH A WEAK SFC BOUNDARY SHIFTING SOUTH DOWN LAKE MICHIGAN...WHICH SHORT TERM MODELS SUGGEST WILL PUSH ACRS EXTREME SOUTHERN LAKE MICHIGAN LATER THIS EVENING. THE AIR MASS AHEAD OF THIS FEATURE NOT PARTICULARLY CONDUCIVE TO WIDESPREAD CONVECTION DEVELOPING AHEAD OF IT SO OTHER THAN SOME SLIGHT CHANCE (ISOLATED WORDING) FOR THIS EVENING ACRS THE FAR NORTH...IT STILL APPEARS THE BETTER PROBABILTIES FOR EVENING CONVECTION WILL BE TIED TO THE MISSOURI MCV AS IT TRACKS ESE WELL TO OUR SOUTH. THE NORTHERN STREAM WAVE ACRS NORTH DAKOTA LOOKS A BIT MORE IMPRESSIVE THAN WHAT MODELS WERE DEPICTING AT THIS TIME YESTERDAY. MODELS CONTINUE TO BRING THIS WAVE ESE INTO THE LAKES REGION TUESDAY AFTERNOON WITH A WEAK COLD FRONT EDGING SOUTH INTO OUR AREA. CONVERGENCE ALONG THE BOUNDARY IS NOT VERY IMPRESSIVE AT ALL BUT WITH THE TIMING OF THE BOUNDARY INTO OUR AREA DURING PEAK HEATING...IT STILL WARRANTS SLIGHT CHANCE (ISOLATED COVERAGE) FOR TUESDAY AFTERNOON. SOMEWHAT COOLER AND LESS HUMID AIR WILL FILTER SOUTH ACRS THE AREA IN THE WAKE OF THE SHORTWAVE TUESDAY NIGHT INTO WEDNESDAY BRINGING QUIET AND PLEASANT WEATHER FOR THE REMAINDER OF THE SHORT TERM PERIOD. LONG TERM...FRIDAY THROUGH MONDAY LONGER RANGE MODELS...AT LEAST THE GFS AND UK...WERE MUCH MORE AGGRESSIVE WITH THE RETROGRESSION OF THE SUBTROPICAL RIDGE ACRS THE CENTRAL U.S...TAKING THE STRONGER 500 MB FLOW FURTHER NORTH AWAY FROM OUR AREA. THE 12Z ECMWF NOT NEARLY AS STRONG WITH THE UPPER RIDGE AS IT TAKES A SERIES OF SHORTWAVES FROM THE LONGWAVE TROF ACRS THE PACIFIC NW AND TEMPORARILY FLATTENS THE RIDGE AXIS TO OUR WEST...KEEPING THE AMPLITUDE MUCH FLATTER OVER THE LOWER 48...WHICH GIVES OUR AREA A BETTER CHANCE FOR SEEING SCATTERED CONVECTION...ESPECIALLY ACRS THE NORTH DURING THE WEEKEND. LOOKS AS IF THE GFS SOLUTION MAY BE OVERDONE...COMPARED TO WHAT IT WAS SHOWING THE PAST SEVERAL RUNS. SO FAR THIS SPRING...THE SHORTWAVES EJECTING ENE FROM THE WESTERN U.S. TROFS AND THEIR ASSOCIATED CONVECTION HAVE BEEN SUCCESSFUL IN KEEPING THE AMPLITUDE OF THE RIDGE ACRS THE CENTRAL PORTION OF THE COUNTRY FLATTER. WILL TEND TO SIDE MORE WITH THE ECMWF THIS PERIOD BUT IT WON'T MAKE MUCH OF A DIFFERENCE IN THE EXTENDED PORTION OF THE FORECAST WITH HOT WEATHER RETURNING FOR THE WEEKEND AND THE HIGHER RAIN CHANCES ACRS THE NORTH. SMITH && .AVIATION... ISSUED 1204 PM CDT MON JUN 17 2013 MAIN CONCERN WITH 18Z TAF SET INVOLVES POTENTIAL FOR POP-UP CONVECTION. MIDDAY SURFACE MAP SHOWS A COUPLE WEAK BOUNDARIES OVER CENTRAL ILLINOIS AND LATEST VISIBLE SATELLITE SHOWING CUMULUS STARTING TO DEVELOP ALONG THEM. THE BOUNDARIES SHOULD NOT MOVE MUCH DURING THE AFTERNOON...BUT DRIER AIR IS SPREADING SOUTHWARD TOWARD THEM. THUS...AM THINKING THAT ONLY KSPI/KDEC/KCMI MAY SEE A THREAT OF THUNDER THIS AFTERNOON...AS THEY ARE CLOSEST TO THE BOUNDARY. COVERAGE CURRENTLY NOT EXPECTED TO BE ENOUGH TO WARRANT MORE THAN A VCTS MENTION AT THESE SITES. ANY THUNDER NEAR THE TAF SITES SHOULD FADE WITH SUNSET. LATE IN THE PERIOD...MAY SEE SOME MVFR CONDITIONS AT TIMES JUST BEFORE SUNRISE...BUT DO NOT THINK IT WILL GET AS WIDESPREAD OR DENSE AS THIS MORNING...DUE TO HIGHER RANGES BETWEEN TEMPERATURE AND DEW POINT.
