Rain showers will be persistent across the Finger Lakes on Monday, but gradually improving conditions are on the way.Low pressure making its way across the Great Lakes has hooked up with a stream of moisture from the Plains. This will result in on and off showers throughout the day Monday, with steadier rain moving in tonight.
The daytime hours on Monday will not be a washout. Showers will be scattered, and there should be ample dry time between batches of showers.
Temperatures are starting the day in the low and mid 40s. With the clouds and showers, expect only a few degrees of temperature rise, with highs in the mid and upper 40s.
Rain will increase this evening into the overnight as the low pressure system approaches with its cold front. Colder air will work in after midnight, and the rain could change to a bit of snow before it ends. This is most likely across the higher elevations of the eastern Finger Lakes, where a fresh coating could fall.
A slot of dry air will work in Tuesday morning, putting an end to the precipitation and resulting in a little sun. Clouds will rethicken briefly during the midday hours and a brief shower will remain possible. By later in the afternoon though, the sun will return as high pressure starts to build in. Temperatures will be a bit cooler on Tuesday, with highs in the mid 40s.
High pressure will take over by Wednesday with a good deal of sunshine. Temperatures Wednesday will still be cool, with highs in the mid and upper 40s after starting in the upper 20s. The high will then set up over northern New England, resulting in a southerly component to our wind for the remainder of the week.
This should bring moderating temperatures to the Finger Lakes, with highs into the 50s Thursday and Friday, with 60s a decent bet for the weekend. Morning lows will mostly be in the 30s. The weather should be sunny and dry into the weekend.
