EXPECT TEMPS TO REACH WELL ABOVE NORMAL AGAIN TODAY WITH MUCH OF THE AREA REACHING THE LOW TO MID 80S. THE CHANCE FOR SHOWERS WILL SNEAK BACK INTO THE FINGER LAKES REGION AND THE SOUTHERN TUG HILL PLATEAU LATE TONIGHT AS THE RIDGE SLIGHTLY BREAKS DOWN AND PUSHES EAST.
MID LEVEL RIDGING ACROSS THE REGION WILL CONTINUE TO DEFLECT THUNDERSTORM COMPLEXES TO OUR NORTHWEST OVERNIGHT.
TEMPERATURES ACROSS THIS AREA WERE COOLER THAN FORECAST AS WELL. THIS HIGH RESOLUTION MODEL/S OUTPUT MAY BE TRYING TO SUGGEST A COLD POOL DEVELOPING UPSTREAM AND BRINGING THE CONVECTION INTO THE FORECAST AREA.
EXPECT ANOTHER QUIET EVENING ACROSS THE REGION WITH WEAK HIGH PRESSURE IN CONTROL. OTHERWISE, IT SHOULD BE MOSTLY CLEAR WITH TEMPERATURES GENERALLY IN THE LOW TO MID 60S.
VSBL SAT IMAGERY SHOWED THAT ENUF MIXING HAD OCCURRED TO DISSIPATE THE LOW CLOUDS OVER NRN WI. THE LOW CLOUDS OVER SRN SECTIONS OF THE FCST AREA SHOULD MIX OUT BY EVENING. MAX TEMPS TO BE COOLER THAN SATURDAY DUE TO THICKER CLOUDS AND SPOTTY RAIN SHWRS MOVING INTO THE AREA. SUNDAY NIGHT THROUGH SATURDAY A SLOW MOVING FRONTAL SYSTEM WITH UPPER LOW SUPPORT WILL LIFT OVER THE NORTHERN PLANS THROUGH THE EARLY PART OF THE WEEK. PROGS HAVE PICKED UP A SLOWER TREND STARTING SUNDAY NIGHT AND HAVE DELAYED THE ARRIVAL OF THE MORE WIDESPREAD RAIN SUNDAY NIGHT DUE TO THE DELAYED NORTH MOVING WARM FRONT.
