Weekend Weather Forecast
An area of high pressure is moving through the region while low pressure moves from the northern Plains into Canada.
Between these two systems, a broad area of southerly flow has developed across the middle of the nation. A leading edge of warmer air is pushing through the Upper Great Lakes this Friday morning.
Clouds associated with the increasing temperatures are spilling over into our region and will keep skies more cloudy than not throughout today. There may even be a brief spit of rain near Lake Ontario, but even if showers show up on radar, most will not be reaching the ground.
We will not get into the southerly flow today with our winds remaining from the northwest. Speeds will generally be under 10 mph, so it won’t be as breezy as the last couple days. Temperatures will stick to the mid and upper 50s, though.
Winds will turn to the south tonight, causing temperatures to rise slightly between midnight and dawn. Most areas will stay in the 40s, and many will be near or above 45 degrees at sunrise.
A few more stray showers will be possible overnight and even very early Saturday morning. Most areas will not see any rain, though.
There should be an increase in sunshine on Saturday, though clouds will still be mixing in. Afternoon highs will be between 65-70 degrees for most areas.
The south wind will increase to 10-15 mph Saturday night, holding temperatures in the low and mid 50s for many areas. Parts of the Southern Tier into Cortland County may still slip back into the 40s.
Winds will continue to increase on Sunday, turning quite blustery. Wind speeds may approach 20 mph with gusts nearing 40 mph.
Skies will be mostly cloudy on Sunday as a new low pressure system approaches. Rain should hold off until after sunset except in western areas like Rochester and the Genesee Valley.
As long as the rain does indeed hold off, afternoon highs should be quite warm, between 70-75 degrees.
Cool, Unsettled Weather
Rain will become widespread Sunday night with some heavier pockets possible. The rain will continue at least into Monday morning, and possibly longer.
Localized rain amounts could exceed 2 inches, but most areas should see a half inch to an inch of rainfall.
Monday will be another windy day, this time with northwest winds. Speeds may again be near 20 mph with gusts around 40 mph.
With clouds, rain, and strong northwest winds, high temperatures should be held to the mid 50s at most.
A completely different low pressure system will move into the Upper Great Lakes on Tuesday, swinging our winds back around to the south. Temperatures should be able to nose back up around 60 degrees, but scattered showers will put a cap on how warm it gets.
This system will redevelop to our northeast on Wednesday and only slowly move into Canada on Thursday, strengthening as it does so.
Scattered showers are very likely on Wednesday. Thursday’s showers may concentrate in the lake effect areas as the warm waters of Lake Ontario enhance the atmosphere’s ability to produce rain.
Temperatures both days will range through the 50s. Thursday’s west-northwest winds may be a bit blustery, but not as strong as Sunday and Monday.
Yet another system will move in for Friday with some showers, which may linger into the early part of next weekend.
Beyond that, high pressure should take over for a mostly quiet final week of October. Some warmer temperatures may be possible once the high passes to our east and the southerly return flow settles in.
