Forecast Discussion:

A low pressure system is moving through the Great Lakes and will slide eastward into our area overnight. The leading edge of precipitation will start off as snow and should begin after ~3am west of Binghamton. A trace to 1” of snow is possible by sunrise for places near/west of Binghamton. Overnight lows will be in the upper 20s to low 30s.

Light snow will move east through the morning Thursday. However, as the atmosphere warms, the snow will change to a mix of sleet, freezing rain and rain before warming enough to support only rain for most of the area by around midday. Snowfall accumulations near/west of I81 should be around a trace-1” with perhaps a few isolated spots higher than that. The snow or wintry mix could persist a bit longer toward the Catskills where slightly higher accumulations of snow are possible in this area. I think 1-3” should be sufficient at this time. Something VERY important to note: accumulations of snow everywhere will be HIGHLY sensitive to the time at which the mixing begins. If the warm air slows down, and the atmosphere stays colder, slightly higher snowfall, sleet or freezing rain accumulations would result. The opposite is true if the warm air arrives faster. This would drastically, or completely, reduce, or eliminate sleet, freezing rain or snowfall accumulations. Rainfall accumulations could range from 0.33-0.75” with a few spots possible reaching 1”. Highs will be in the upper 30s to low 40s. Please monitor the forecast.

The chance of rain and snow showers will return Thursday night. Lows will be in the 30s. Occasional, scattered rain or snow showers will be around the area Friday. The chance of precipitation is 40%.

Saturday may bring a few sprinkles, but it looks like we’ll see more dry time than wet. A few sprinkles or showers could hang around Sunday, but it does not look like a washout. The chance or rain is 30% Highs will be around 55 Saturday and near 50 Sunday. By next Monday & Tuesday sunshine returns and highs rise through the 50s.
