Clouds Persist Despite High Pressure
A large area of high pressure is moving into the Finger Lakes region, but a continued northerly flow off of Lake Ontario will make it hard for any sunshine to make it out.
Instead, Tuesday will feature more of the same with plenty of low-level clouds and some spots of drizzle.
With the clouds and north wind in place, temperatures will only rise a few degrees from the relatively warmer morning lows.
Temperatures will take all day just to rise from the mid 30s to an afternoon high around 40 degrees.
As the high pressure passes through, the wind will eventually swing around to the south this evening. The drizzle should end and at least some of the cloud cover will start to break up.
This should allow temperatures to slip back into the upper 20s tonight with the south wind preventing temperatures from falling much further.
A Window for some Sun
The Finger Lakes will then have a brief window for some sunshine during the first part of the day on Wednesday.
Skies may even become mostly sunny for a time before thin clouds high in the atmosphere begin to filter in from the west by the late morning.
The clouds should increase and thicken Wednesday afternoon as the next weather system presses east into our region.
With the extra sunshine and continued southerly flow, temperatures should be able to reach the upper 40s on Wednesday. One or two places along or north of I-90 could even touch 50 degrees.
Rain Moves Back In
Rain will start to move back into the Finger Lakes as early as the late afternoon on Wednesday, when a few scattered showers may impact more western areas.
Generally, though, most of the Finger Lakes should remain dry until after about 8 pm, when more widespread rain showers move in.
After an initial batch of widespread, steadier light rain, on and off showers will continue throughout the night and well into the day on Thursday.
Rainfall amounts are expected to be light, with most areas seeing a couple of tenths of an inch of precipitation.
All of the precipitation is expected to fall as rain with temperatures around 40 degrees Wednesday night and into the mid 40s on Thursday.
If precipitation lingers long enough Thursday evening, a few snowflakes may start to mix in over the higher elevations of the eastern Finger Lakes, but with no accumulation expected.
Friday will turn sunny behind this system before another storm system moves in for the weekend.
