Watch for slick spots
High pressure over the Great Lakes is preventing the northward progression of a large storm system over the southeastern United States.
Precipitation will work hard to move north over the next 24-36 hours, but how successful it ends up being is questionable.
Saturday will remain a cloudy day with a couple shower or areas of drizzle. These will be most likely across the Southern Tier.
Temperatures today will reach the upper 30s to near 40 degrees, so precipitation will remain all rain.
By Sunday morning, low pressure will be along the coast of Delaware while the high pressure will be over Maine. Precipitation will continue to attempt to move into the Finger Lakes.
During this time, temperatures at the surface will be below freezing with morning lows in the mid and upper 20s. However, there will be warmer air aloft.
If precipitation makes it north of the NY/PA State Line, some freezing rain will be possible. This could mix with sleet or snow. The exact precipitation type is very uncertain.
Any precipitation that works in Sunday morning should be light, but even a glaze of ice can make travel difficult.
The National Weather Service may issue Winter Weather Advisories later today if confidence rises in an icing event.
In my opinion, it is best to prepare for the possibility of icy pockets through the late morning hours Sunday. Hopefully the precipitation fails to move far enough north though.
The potential also remains for a period of squally weather on Monday as a cold front moves through. The timing, intensity, and likelihood of such an event is still uncertain.
I’ll have another quick update early Sunday morning.
