Monday may be Snowy!

    We should see some light snow today, and into tonight. Amounts should generally be less than 3in , the heavy snow may come later Sunday-Monday.  The snow Sunday- Monday will be Lake Effect snow, this is caused by cold air passing over a relatively warm lake.  Usually the heaviest Lake Effect stays North of Syracuse , but on Sunday night the winds will shift to a North-West flow. This usually sets up a heavy band in Syracuse and across the South Central NY.  There is potential for this band to become intense , mainly depends on exact wind direction and amount of moisture in the atmosphere.

     As seen above in the forecast sounding there will be both a favorable cold wind flow over Lake Ontario, and a very moist atmosphere.  Although it is nearly impossible to predict the exact location of the band this far in advance. It seems likely that areas in Onondaga, Cayuga, Madison, and Cortland Counties will see a very cold and snowy Monday AM.  The rest of next week looks like an average week, with a few more chances for snow and temperatures in the 20s , by the end of next week we should warm slightly into the the mid to upper 30s.
