Out ahead of the approaching cold front will be the place to be today, winds out of the south will help push temps into the upper 50’s and even low 60’s today, but trouble brews to our west. A look a temps across the NE today help to clearly define the location of our approaching cold front by this afternoon.
Near 30 degree temp difference out ahead of the front verses behind it, this cold front will be responsible for a much different day of weather tomorrow. Behind this front colder air riding on brisk NW winds will help fire up the first significant lake effect snow event for the snow belt regions of western NY. The low pressure system responsible for the incoming cold front will become cut off from the flow and slowly track east through New England. This will keep the atmosphere quite dynamic though Monday with snow squalls from the lakes and snow fall from the lift created by out cutoff low.
The areas that are most likely to see accumulating snowfall are the Catskills (especially western Catskills) with Delaware County currently under a Lake Effect Snow Advisory, the Taconic’s and the higher elevations and hill towns across our region. We will likely see flakes down to the valley floor but any accumulations in these areas look unimpressive at best with maybe a coating in areas that can get into a persistent squall. Below is a look at the GFS models thoughts on accumulations.
The cold front looks to sweep across our region between 11PM and 1Am, its passaged will be marked but a period of rain, followed by increasing winds out of the NW and temps falling quickly into the morning hours. Our day on Sunday and into Monday will be marked with a persistent NW wind, temps struggling out of the 30’s and 40’s, accumulating snow across our higher elevations, and periods rain and snow squalls across the valley locations.
