AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DULUTH MN 233 PM CDT SUN JUL 16 2006 .DISCUSSION...ANOTHER WARM AFTERNOON WITH MANY 90S ACROSS OUR CWA. LAKE BREEZE KICKED IN EARLY THIS AFTERNOON...COOLING THE IMMEDIATE LAKESHORE AREAS UP THE SHORE...DOWN TO THE TWIN PORTS AREA. HUMIDITY IS A BIT HIGHER...AND THE HEAT INDEX IS AT OR IN SOME CASES SLIGHTLY HIGHER THAN YESTERDAYS VALUES AND WAS RUNNING FROM 90-103 MOST AREAS. A WEAK CONVERGENCE AXIS WAS DRAPED ACROSS OUR CWA...JUST NORTH OF KXVG-KCOQ EAST OVER LAKE SUPERIOR. CONVERGENCE ALONG THIS BOUNDARY IS WEAK IN THE LIGHT LOW LEVEL FLOW. THERE IS HOWEVER PLENTY OF INSTABILITY THIS AFTERNOON...WITH SBCAPES FROM 2000-2500 J/KG OVER MUCH OF OUR CWA...AND MLCAPES MORE VARAIBLE ACCORDING TO SPCS RUC ANALYSIS. THERE ARE POCKETS OF 2000-2500 J/KG. ONE OF THE LIMITING FACTORS IN GETTING THUNDERSTORMS TO DEVELOP HAS BEEN HIGH CIN VALUES. RUC FORECASTING DECREASING CIN VALUES...WITH LESS THAN 25 IN SPOTS OVER NORTHERN WISCONSIN WEST INTO NORTHERN MINNESOTA AT 19Z. HOWEVER...NAM BUFR SOUNDINGS SHOW A STRONG CAP REMAINING IN PLACE FOR THE REST OF THE AFTERNOON AND EVENING. 06Z NAM DID SHOW A WEAKENING CAP AROUND 22Z. THE TRUTH IS PROBABLY SOMEWHERE BETWEEN THE TWO EXTREMES. LATEST RADAR AND SATELLITE VISIBLE IMAGERY SHOW CU FIELD FORMING OVER NORTHERN MINNESOTA. HIGH CLOUDS HAVE BEEN INCREASING OVER OUR SOUTHERN MN ZONES INTO NORTHERN WISCONSIN...WHICH IS BLOW OFF FROM SOUTHERN-CENTRAL MINNESOTA SHOWERS/THUNDERSTORMS. WE WILL CONTINUE TO CARRY 20-40 PERCENT POPS TONIGHT WITH UNSTABLE AIRMASS IN PLACE AND A WAVE AND BOUNDARY TO MOVE THROUGH. INITIATION TIME OF STORMS IS NOT CLEAR CUT. A WAVE MOVING THROUGH SOUTH DAKOTA WILL HELP WEAKEN THE CAP AND PROVIDE LARGE SCALE LIFT LATER THIS EVENING...AND THE WEAK SURFACE BOUNDARY ALREADY IN PLACE COULD BE ENOUGH TO GET A FEW STORMS GOING AS WELL YET THIS AFTERNOON. 875/900MB WINDS WILL BE INCREASING THIS EVENING AS WELL TO 30-35KT...JUST AHEAD OF THE TROUGH BETWEEN 00-03Z. IF STORMS DO GO...THERE IS PLENTY OF SHEAR IN PLACE FOR ORGANIZED STORMS...WITH SEVERE WINDS AND SOME HAIL THE MAIN THREATS. THE COOL FRONT WILL MOVE THROUGH OUR CWA MONDAY MORNING...WITH HIGH PRESSURE BUILDING IN BRINGING COOLER TEMPERATURES AND LOWER HUMIDITY. LOW LEVEL FLOW WILL TURN BACK OUT OF THE SOUTH ON TUESDAY...WITH A CHANCE FOR MORE THUNDERSTORMS TUESDAY NIGHT INTO WEDNESDAY AS A TROUGH AND SHORTWAVE SWING THROUGH. A BLEND OF NAM/GFS MOS WAS USED FOR TEMPERATURES. && .POINT FORECAST TEMPS/POPS...
