Sleet, Freezing Rain and Flooding Possible This Weekend in CNY

We have a chance of sleet, freezing rain, localized flooding and temperatures ranging from the low 30's to the upper 70's.

The National Weather Service out of Binghamton says rain is expected to develop Sunday night and Monday, ahead of a slow moving cold front. Some of this rain could be heavy, with the potential for 1 to 2 inches of rainfall. If rainfall of this magnitude materializes, minor flooding would be possible.

A warm front will set up across Central New York Friday night through Saturday. Temperatures will be very mild on the south side of the front, while areas to the north will be significantly cooler and experience more shower activity.

On Saturday afternoon the National Weather Service says temperatures will likely fall
throughout the afternoon. A concern is the low-level cold air could be cold enough for a change to sleet and freezing rain across Finger Lakes northeastward into the Rome and Syracuse areas. It is somewhat concerning that the model that fairs well in these situations the NAM is most aggressive with the influx of low- level cold. A potential 30-40 temperature spread across the region is very possible with 60`s and even 70`s south of the boundary and 30`s or 40`s north of the boundary for highs.

The front will start to wobble through the region on Sunday with temperatures in the 30's and 40's north of the boundary and 50`s and 60`s south of it On Sunday. Cold air is showing up down the Poconos and northward into the Catskills and a warm-up from
Binghamton westward toward Elmira. The exact location of the front is still highly uncertain. Southerly winds will be on the increase ahead of the cold front with 20-25 mph gusts Sunday night and Monday.

Sunday into Monday expect a widespread 1- 2-inch rain event across the region. The system along with lingering cold may keep the strongest winds over 25 mph aloft and should keep the threat of thunderstorms in check as well. However, both the NAEFS and GEFS show several locations with the potential of minor to perhaps localized moderate flooding across the region.

Rain will mix with and change over to snow showers Monday night into Tuesday.
