AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN 339 PM CDT TUE AUG 22 2006 .DISCUSSION...TONIGHT THROUGH FRIDAY STRONG WARM ADVECTION IS OCCURRING ACROSS THE DAKOTAS ATTM IN RESPONSE TO A CONFLUENT JET PATTERN ACROSS THE WESTERN GREAT LAKE REGION INTO SOUTHWEST MANITOBA. THE GFS AND NAM/WRF HAVE BOTH BEEN QUITE ERRATIC ON PLACEMENT OF VARIOUS SYNOPTIC FEATURES AS A RESULT OF LARGE CONVECTIVE FEEDBACK PROBLEMS. WE ENDED UP TURNING TO THE NGM FOR A SIGNIFICANT PART OF OUR NWP GUIDANCE. THE CONSISTENT FEATURE OF ALL MODEL RUNS FROM MONDAY ON HAS BEEN THE EVENTUAL DEVELOPMENT OF A STRONG LOW LEVEL JET WITH A 45 TO 55 KNOT SPEED CORE. THE LOW LEVEL JET INITIALLY IS ORIENTED SOUTH TO NORTH OVER EASTERN SOUTH DAKOTA..BUT BECOMES TILTED INTO A WEST- SOUTHWEST TO EAST-NORTHEAST ORIENTATION TOWARDS SUNRISE WEDNESDAY. THIS LOW LEVEL JET IS SEEN DRIVING A LARGE FLUX OF MOISTURE INTO OUR WESTERN CWA COUNTIES EARLY THIS EVENING...SETTING THE STAGE FOR THE EVENTUAL DEVELOPMENT OF A STRONG BOW ECHO WHICH WILL CROSS OUR CWA OVERNIGHT. PWAT VALUES INCREASE FROM THEIR CURRENT VALUES OF 0.50 TO 0.60 INCHES TO 1.75 INCHES OVERNIGHT...A REMARKABLE INCREASE. HEAVY RAINFALL RATES...LARGE HAIL AND DAMAGING WINDS HAVE BEEN WORKED INTO OUR GRIDS FOR SUCH AN OUTCOME. VARIOUS MODEL OUTPUT FROM 12Z AND 18Z TODAY SUGGEST DEEP LAYER SHEAR (I.E. ZERO TO 6 KM) WILL PEAK AT 55 TO 65 KNOTS BETWEEN 06Z AND 15Z WEDNESDAY OVER OUR EAST CENTRAL MN COUNTIES INTO A FEW OF OUR WISCONSIN COUNTIES. WHAT IS EVEN MORE IMPRESSIVE IS THAT 40 KNOTS OF THIS SHEAR IS DIAGNOSED TO BE IN THE 0-1 KM LAYER. ALL OF THIS SUGGESTS A VERY FORMIDABLE BOW ECHO WHICH WILL LIKELY TRANSLATE FASTER THAN THE MEAN WIND SPEED AND FEATURE WIDESPREAD DESTRUCTIVE WIND POTENTIAL. FEEL THAT CONVECTIVE POTENTIAL WILL REALLY DROP OFF AFTER MIDMORNING WEDNESDAY AS AIRMASS GETS WORKED OVER...BUT WE CARRY POPS OVER THE REMAINDER OF THIS FORECAST SEGMENT IN DEFERENCE TO OUR NEIGHBORS. LONGER TERM...FRIDAY NIGHT THROUGH WEDNESDAY STILL QUITE A BIT OF VARIATION AMONG MODELS AND DPROG OF GFS AT LEAST IN THE BEGINNING OF THE LONGER TERM. PRECIPITATION EVENT SHOULD BE NEARING ITS END FRIDAY NIGHT OR SATURDAY AS TROUGH MOVES THRU. GFS LOOKS QUITE STRANGE FOR AUGUST WITH DEEP CLOSED LOW MEANDERING EAST ALONG CANADIAN BORDER EARLY IN WEEKEND...A PATTERN MORE TYPICAL OF LATE SEPTEMBER. SHOULD SEE A DRYING PERIOD BEGINNING SATURDAY AND CONTINUING INTO EARLY NEXT WEEK AS RIDGING BEGINS TO OUR WEST && .MPX WATCHES/WARNINGS/ADVISORIES... MN...NONE. WI...NONE. && WET/BAP
