ALY LONG TERM /THURSDAY THROUGH SUNDAY/...
BY FRIDAY NIGHT A STORM SYSTEM WILL BE MOVING INTO THE WESTERN GREAT LAKES WITH A WARM FRONT APPROACHING THE ALBANY FORECAST AREA. OVER RUNNING PRECIPITATION IS EXPECTED FRIDAY NIGHT AND SATURDAY.
PRECIPITATION TYPE BASED ON 00Z GFS AND 00Z/EURO USING TOP DOWN METHODOLOGY PRODUCES A MIXED BAG. INITIALLY STARTING AS SNOW AND SLEET FRIDAY NIGHT...TRANSITIONING TO SLEET AND FREEZING RAIN EARLY SATURDAY...TO MOSTLY RAIN BY LATER SATURDAY.
MODEL SOLUTIONS START TO DIVERGE BY LATER SATURDAY. BOTH MODELS HAVE THE WAVE MOVING THROUGH THE GREAT LAKES BUT MAIN DIFFERENCE IS THAT 00Z/GFS SOLUTION IS ABOUT 300 MILES EAST OF 00Z/EURO WITH TRACK OF SURFACE WAVE. THE TRAILING COLD FRONT IS ALSO ABOUT 300 MILES FURTHER EAST IN THE 00Z/GFS. THIS HAS IMPLICATIONS FOR SUNDAY BECAUSE BOTH MODELS HAVE SECONDARY LOW DEVELOPMENT ALONG THE TRAILING COLD FRONT.
THIS LOW DEEPENS AS IT MOVES FROM THE SOUTHEAST U.S. NORTH NORTHEASTWARD. 00Z/EURO WOULD TRACK THE LOW WEST OF INTERSTATE 81 ACROSS LAKE ONTARIO BY MONDAY MORNING...WHILE 00Z/GFS HAS THE LOW MOVING SOUTHEAST OF CAPE COD. QUITE A SPREAD.
