Daily forecast discussion…

That weak disturbance that was in the southern Plains, is moving north and east and is heading into the great Lakes, there is also a piece that broke off the disturbance that is passing just to our south.

High pressure is supplying plenty of sun with temperatures a little warmer than yesterday the surface chart and satellite imagery is showing, a weak disturbance is approaching this is heading into the great Lakes, there is also a piece that broke off the disturbance that is passing just to our south.

Clouds will be on the increase, then rain showers will develop late today, these will move north and east tonight into Saturday. We will have a little cold air wedged in, that will allow for a bit of freezing drizzle/rain.  The ice won’t be heavy but some could see upwards of tenth of an inch, especially in the higher elevations and those sheltered valley locations. It doesn’t take much ice to cause issues, so the NWS has issued Winter Weather Advisories for parts of the region. Temperatures will be warming so the ice will change over to plain rain. The 2^nd piece of this system will pass just to our west on Sunday, this will allow for more in the way of widespread rain for the region for Sunday into Monday, there will be a southern flow that will usher in much warmer temperatures for Sunday. These mild temperatures will hang round through Tuesday.

With the rain and snowmelt, flooding will be a concern for some areas.  

Most of Monday into Tuesday looks to be dry, then another system will approach bringing rain showers later afternoon these will be move west to east, by the time for New Years Eve celebrations we can expect rain to be an issue.  The rain will go into New Year’s Day, then cold air is going to wrap in behind the system, changing rain over to a mix and some snow on the backside for parts of New York State and northern Pennsylvania this will be especially true for the higher elevations. We can also expect lake effect snow downwind of the Great Lakes. All of this will move east during the day. Bringing a mix and some snow to northern parts of New England.  Areas south of this should see just rain that will be winding down during the day.

High pressure will be building in behind bringing in colder weather. The weather will be unsettled for Friday into next weekend.
