Area forecast discussion, Jul 22, 1:08 PM CST, 1 hour 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 208 PM CDT WED JUL 22 2009 .DISCUSSION... EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP AGAIN THIS AFTERNOON...AS INSTABILITY INCREASES AND A SHORTWAVE MOVES ACROSS CENTRAL MN. THE LOW FREEZING LEVEL HEIGHT OF ABOUT 8500-9000 FEET WILL BE CONDUCIVE TO A HAIL THREAT WITH THE THUNDERSTORMS THAT DEVELOP. FUNNEL CLOUD REPORTS ALSO MAKE SENSE GIVEN THE AXIS OF SURFACE VORTICITY THAT LIES ALONG THE WEAK TROUGH EXTENDING FROM NEAR MORA...TO THE TWIN CITIES...TO MANKATO. HOWEVER...THE STORMS THUS FAR HAVE QUICKLY BECOME OUTFLOW DOMINATED...WHICH MINIMIZES THE TOUCHDOWN THREAT. CONVECTIVE ACTIVITY WILL WANE AFTER SUNSET...WITH THE NEXT CHANCE OF SHRA/TS ARRIVING LATE THURSDAY AND FRIDAY AS A MID LEVEL LOW DIVES SOUTHEAST FROM MANITOBA ACROSS NORTHERN MINNESOTA...AND PUSHES A COLD FRONT ACROSS THE UPPER MIDWEST. ALTHOUGH THE FRONT WILL BE PAST THE FORECAST AREA BY SATURDAY...THE AFOREMENTIONED LOW WILL SPIN OVER THE GREAT LAKES REGION THROUGH THE WEEKEND AND BRING THE POTENTIAL FOR ISOLATED SHOWERS AND THUNDERSTORMS...MAINLY ACROSS WEST CENTRAL WISCONSIN ON SATURDAY AFTERNOON. OTHER THAN A ROGUE SHOWER OR TWO IN WEST CENTRAL WI...EXPECT SUNDAY TO BE A DRY DAY. BY NEXT WEEK...THE GREAT LAKES LOW WILL BECOME PART OF THE LARGER LOW DOMINATING CANADA. THE WESTERN PERIPHERY OF THE LOW WILL PIVOT SOUTH ACROSS THE NORTH CENTRAL CONUS DURING THE FIRST HALF OF THE UPCOMING WEEK. THIS WILL TRANSLATE TO SPORADIC PRECIPITATION OPPORTUNITIES AS EMBEDDED IMPULSES MOVE ACROSS THE REGION...ALONG WITH BELOW NORMAL TEMPERATURES. HIGHS WILL LIKELY NOT ESCAPE THE 70S ACROSS MUCH OF THE FORECAST AREA FROM WEDNESDAY THROUGH MONDAY. HAVE ALSO RETAINED 20-30 POPS FROM MONDAY THROUGH WEDNESDAY. && .AVIATION.../18Z TAF ISSUANCE/ DISTURBED UPPER LEVEL PATTERN REMAINS OVER THE AREA THROUGH EARLY EVE. COUPLED WITH A WEAK SFC BOUNDARY OFFERING LOW LEVEL CONVERGENCE AND POOLING OF INSTABILITY...SCATTERED THUNDERSTORMS ARE ALREADY DEVELOPING IN NRN MN AND WI. THESE SHOULD EVOLVE SOUTH INTO ERN MN AND WRN WI THROUGH MID AFTN. WITH THE TIMING OF THESE IN THE FIRST SIX TO NINE HOURS...HAVE FOCUSED THE WINDOW ON MENTIONING RAIN AT ERN MN AND WRN WI TAF SITES. HAVE HIGHLIGHTED THUNDER IN THE WI TAF SITES BUT IS VERY POSSIBLE AT ERN MN SITES DUE TO THE LOW FREEZING LEVELS OFFERING SUFFICIENT CHARGE DISTRIBUTION FOR LIGHTNING. THERE COULD ALSO BE AT LEAST SOME SMALL HAIL WITH ANY STORMS THIS AFTN. ALL IN ALL...COVERAGE SHOULD BE NEAR 20-30 PERCENT IN ERN MN TO 30-50 PERCENT IN WRN WI. STORMS WILL FADE WITH THE LOSS OF HEATING INTO THE EVENING. WINDS WILL BE SOMEWHAT VARIABLE AT TIMES THIS AFTN AND BE GUSTY NEAR ANY STORMS. THESE WILL BECOME VERY LIGHT ONCE AGAIN TONIGHT AND WITH RESIDUAL MOISTURE IN THE WAKE OF THE SCT SHOWERS THIS AFTN AND EVE...SOME FOG IS AGAIN POSSIBLE IN ERN MN AND WRN WI. NOT AS IDEAL OF A SETUP...BUT SOME DENSE FOG NEAR WI TAF SITES IS POSSIBLE.
