Tuesday-Wednesday Weather

A narrow wedge of high pressure is squeezing into the Finger Lakes between low pressure over the Atlantic and low pressure over the Upper Great Lakes.

Most of the area is still cloudy this morning, but some clearing took place overnight for the far eastern Finger Lakes. These areas are cooler this morning but starting with some sun.

Overall, there will be more clouds than sun throughout the region today, but most areas should see a bit of both.

Rain will be hard to come by today, but a stray shower or two will pop up late this afternoon. The best chance for rain looks to be across Ontario, Livingston, Yates, and northern Steuben counties.

Temperatures will rebound with the lack of rain and partial sunshine, despite little to no wind blowing. Look for highs mostly in the low 60s with a few upper 50s in the southwestern quadrant of the region.

Skies will see more clearing overnight, but a few clouds will still be scattered about. No precipitation will fall overnight. Temperatures will fall to near or just above 40 degrees.

Wednesday will start off with a good deal of sunshine. By midday, skies will turn mostly cloudy as fair weather cumulus clouds develop and become rather thick.

Winds will be light and variable again, but a bit stronger than today. Temperatures will gain a couple more degrees, mostly reaching the mid 60s.

Unsettled Weather Returns

Scattered showers will develop Wednesday afternoon and continue into the evening. Not all areas will see rain during this time, but it will not be too uncommon.

The rain should increase in coverage after midnight Wednesday night, becoming a widespread steady rain by Thursday morning.

The trend in the models has been to push the precipitation eastward, so the southwestern quadrant of the region may dry out as early as noontime Thursday. If trends continue, steady precipitation Thursday afternoon may even become limited to the I-81 corridor.

Rain showers, mixing with snow at times, will rotate back into the region Thursday night and into Friday. This precipitation will not be as steady as the initial rain, but will make for another pair of chilly, damp days.

High temperatures both Thursday and Friday will struggle to the mid 40s with morning lows in the mid 30s.

The rain should pull out for Saturday, leaving a mix of sun and clouds. Temperatures will bounce back with the removal of the rain, settling on highs in the mid 50s, which is spot on the climatological daily average high.

A new batch of unsettled weather will spread some scattered showers in for Sunday and Monday, but neither day looks like a complete washout. Temperatures will stick close to average, with mid 50s Sunday and perhaps upper 50s Monday.

Unsettled weather will continue next week with highs staying near or a touch below average.
