Enjoy the warmth while it lasts.
Today’s temperatures will reach into the low 70s, but on Tuesday Western New Yorkers will wake up to snow.
“It will be quite a shock in the morning when they wake up,” said National Weather Service meteorologist Jim Mitchell.
The 40-degree temperature swing isn’t out of the ordinary for April, according to Mitchell.
Today’s temperatures are 20 degrees above normal, and Tuesday’s will be 20 below normal.
“Typical April-type pattern,” Mitchell said. “Go from nice and balmy and warm and summery to wintery.”
The swings are due to cold air to the north, and warm air to the south.
After a balmy day today, a strong cold front will come through tonight, with rain showers falling overnight, before it switches to snow, or perhaps sleet or freezing rain.
Snow will begin between 4 and 6 a.m. Tuesday, with temperatures around freezing, and then will drop to 20 degrees on Tuesday night and Wednesday morning, which will be close to record cold for Wednesday.
Snow will be heaviest in the morning and will taper off in the afternoon. Accumulations will be slight because the ground is warm, but the lower elevations could see one to two inches, and the higher elevations could see two to four inches.
