It is a rainy Tuesday morning across the Finger Lakes as a storm system passes by to our west.
The rain should continue until the noon to 2pm time frame, after which it will move out of our region. The rest of the day should be mostly cloudy and comfortable, with highs around or just above 50 degrees.
After a quiet night, a storm system will develop over the middle of the country on Wednesday. This storm system will push a warm front through on Wednesday afternoon. Unseasonably high moisture levels will accompany this front with another area of rain.
The heaviest rain will likely push from the Mid Atlantic into New England, but showers should break out across the Finger Lakes Wednesday afternoon. This will likely be a quick shot of rain, but some of it could come down hard at times. By the late afternoon and evening hours, the rain will taper to a few scattered showers.
Temperatures Wednesday afternoon will reach the mid 50s, but after the rain ends, warmer air will flood the region. Temperatures will rise Wednesday night. By dawn of Christmas Eve, most of the Finger Lakes will already be in the 60s.
How high the temperature goes on Thursday may have to do with how much sun breaks out and how quickly a cold front moves through. Currently, mid to upper 60s look likely, but I would not be surprised to see some spots hit 70 degrees. A few showers will be possible along the front, with cooler weather starting to work in by Thursday evening.
The temperatures for Christmas and the weekend are highly uncertain. Much colder air will be lurking just to our northwest, while the very warm air settles just to the south. More rain is likely on Christmas Day and Sunday as storm systems ride along the temperature boundary.
Eventually, it looks like the cold air may win out for a change. Temperatures for the last few days of 2015 may end up closer to normal. This could be a sign of things to come, with multiple indications starting to show in the models of a pattern flip towards winter. Stay tuned.
