Chilly & Breezy Thursday
An area of high pressure will be the dominate weather force in the Finger Lakes for the next two days, bringing a nice warm-up Friday after a chilly Thursday.
Lake effect precipitation has dried up over the Finger Lakes overnight and skies have become mostly clear as the high begins to build in.This high pressure system is still back over the Midwest, placing our region on the cold side of the system.
Temperatures this morning are in the low and mid 30s with a few places starting in the upper 20s.
Northwest winds will remain in place ahead of the high pressure with gusts of 25-30 mph from Cayuga Lake westward and 30-35 mph to the east. This will keep the cold air in place throughout the day.
High temperatures will range throughout the low 40s. Higher elevations may not get beyond 40 degrees.
By the evening hours, high pressure will pass through Pennsylvania, causing our wind to turn first to the west, then southwest. Temperatures will quickly drop into the mid and even low 30s this evening, but then should hold steady overnight.
Much Warmer Friday
Friday will start with more sunshine and a strengthening southwest wind.
While the wind Thursday will hold temperatures to a rise of only about 10 degrees, on Friday, we should see a jump of 25-30 degrees throughout the day.
High temperatures Friday afternoon will top out in the upper 50s and low 60s across the area, which is much closer to normal for mid-October.
Wind gusts on Friday should top out between 20-25 mph.
The sunshine will probably not hold the entire day though. Thin cirrus clouds will announce the approach of a new weather system. These clouds should thicken late in the day and a couple of showers may start to arrive as soon as the evening.
With the increase in cloud cover and continuation of the southwest wind, temperatures Friday evening will only drop back into the upper 40s and low 50s with Saturday morning lows generally at or above 45 degrees.
Unsettled, Cool Weekend
A cold front will move through the Finger Lakes during the first half of Saturday, bringing an abrupt end to the warmer weather.
Temperatures should still reach the low and mid 50s on Saturday ahead of the front.
Showers will be likely, though it will probably not be a steady rain. A period of fewer, lighter showers seems likely during the afternoon and the precipitation may cease all together during the evening.
Temperatures will fall back into the mid 30s by Sunday morning and lake effect will develop across our area.
A spray of rain and snow showers will develop during the predawn hours on Sunday and persist through the morning. The precipitation should break up with the daytime heating, though high temperatures Sunday will struggle even to make it to 40 degrees.
More gusty winds are likely Sunday as well, with top gusts of 30-40 mph commonplace.
