ROCHESTER, N.Y. – A ridge of high pressure continues to slowly move east across the Great Lakes. What has changed is the gusty wind has diminished significantly, but the dry Arctic air remains through this Sunday night into Monday morning.
With a deep snowpack, light winds, and very dry airmass, we have the ingredients for temperature to dramatically fall overnight. This drop in the mercury will be highly dependent on the amount of cloud cover during the overnight as the clouds act as a blanket over the atmosphere and can reduce the amount of outgoing heat. In any event many communities, especially south of Rochester, will find the temperature plummeting well below zero. There is no threat of a record for Monday morning as the coldest temperature ever recorded on this date is -22 degrees which was set back in 1934. That is the coldest temperature measurement in recorded history for Rochester.
Monday should bring breaks of sunshine for the morning with the clouds increasing for the afternoon. The high temperature will approach 20 degrees. Tuesday will likely feature a few snow showers for the morning, but little or no accumulation is expected. It will turn noticeably milder for Tuesday with the high temperature in the mid-30s. This will likely be the first time the temperature has risen above freezing in almost two and a half weeks!
