MODELS APPEAR IN GOOD AGREEMENT THROUGH PERIOD. GFS QPF LINING UP BEST WITH WHAT IS HAPPENING CURRENTLY SO WILL USE FOR DETAILS. IN THE NEAR TERM WILL BE WATCHING BAND OF TSRA FROM VCNTY SFC LOW OVER FAR NE ND EASTWARD ALONG SURFACE BOUNDARY ALONG MN/CANADIAN BORDER. AIRMASS HAS JUST ENOUGH INSTABILITY AND CAPE (400JKG) AIDED BY 35KT LOW LEVEL JET AND SHORT WAVE ENERGY. MODELS SHIFT FEATURES EAST BY 12Z SO WILL MONITOR TRENDS FOR AM MENTION. OTHERWISE COLD FRONT THROUGH DVL WITH RUC INDICATING FRONT THROUGH FA BY 15Z. STRONG COLD ADVECTION DURING DAY WILL PUT THE KIBOSH ON TEMPERATURE RECOVERY TODAY. ALSO DEEPER LAYERED DROPS INTO FA LATE AM INTO THE AFTERNOON AND WITH COLD CONVECTIVE TEMPERATURES WILL SEE CLOUD COVER FURTHER INHIBITING TEMPERATURE RECOVERY.

AIRMASS REMAINS SLIGHTLY UNSTABLE HOWEVER ANY CAPE SHIFTS EAST AND LOW LEVEL CONVERGENCE WILL BE LACKING SO ON THE FENCE WITH LATER PERIOD T MENTION. WIND ALSO AN ISSUE. NOT A CLEAR CUT ADVISORY SITUATION FOR A COUPLE OF REASONS. LOW LEVEL COLD ADVECTION OUT RUNS PERIOD OF STRONGEST WINDS WHICH MAY LIMIT DOWNWARD MOMENTUM TRANSFER. ALSO CLOUDS MOVING IN MAY LIMIT MIXING POTENTIAL. WILL STILL BE WINDY GRANTED BUT AT THIS POINT WILL LIMIT ADVISORY TO AREAS WEST OF VALLEY AND DAY SHIFT CAN ADJUST IF STRONGER WINDS CAN SHIFT EAST INTO VALLEY. AS TROUGH DIGS INTO THE GREAT LAKES TONIGHT MODELS SHOW IMPULSES SLIDING DOWN BACK SIDE OF FEATURE TO KEEP SOME POPS GOING ACROSS THE EAST TONIGHT. CLOUDS AND/OR WIND WILL LIMIT TEMPERATURE DROP EVEN AS COLD AIR CONTINUES TO FILTER IN. COLD ADVECTION LEVELS OFF MONDAY HOWEVER WITH MOIST LAYER AND CONVECTIVE TEMPERATURES AROUND 50 WILL LIKELY SEE MORE CLOUDS THAN SUN LIMITING RECOVERY. SURFACE RIDGE AXIS RIGHT OVER VALLEY REGION AT 12Z TUESDAY AND WITH DRY...COOL AIRMASS WILL NEED TO MENTION POTENTIAL FOR FROST. MID LEVEL RIDGE AXIS SHIFTS OVER FA WITH COLUMN WARMING TOWARDS MIDWEEK ALONG WITH INCREASED MIXING. THIS SHOULD GET TEMPERATURES BACK TOWARDS AVERAGE.
