Increasing Sunshine Monday

Monday is starting out where Sunday left off across the Finger Lakes, but the majority of the week will have very quiet weather.

Clouds and a few showers will continue this morning into the late morning and midday hours before our weather starts to shift. None of the rain will be heavy and not all locations will see precipitation.

This rain is being triggered by an area of enhanced winds within the jet stream. The jet stream, which is a current of air roughly 35,000 feet above the surface, will play a major role in keeping the rest of the week quiet.

Currently, the jet stream is entering the United States over the Pacific Northwest before shooting far north into Canada. The jet stream then comes back south into northern New York and New England. For areas south of the jet stream, which includes most in the country, the weather is quiet and mild.

As the area of enhanced winds travels along the jet stream, showers will move south and clouds will dissipate from north to south this afternoon.

Temperatures will top out with highs in the upper 60s to near 70 degrees. Clear skies this evening will lend to quickly falling temperatures. Most areas should bottom out in the upper 40s and low 50s overnight. Areas of fog are likely by Tuesday morning.

Sunny, Quiet Weather

The jet stream will gradually shift east over the next several days, allowing our weather to stay quiet while also warming up.

A daily pattern of morning fog quickly turning over to bright, sun-filled skies should set up for the remainder of the week and into the weekend. There will be very little day-to-day variability.

Tuesday and Wednesday should see high temperatures reach the low 70s. Thursday and especially Friday should reach the mid 70s.

Each day through Friday should have morning lows in the upper 40s and low 50s. The coldest temperatures, as usual, will be across the Southern Tier with the warmest readings near the lakes.

By the weekend, temperatures should warm up even more. Saturday’s high should come in near or just above 80 degrees while Sunday pushes into the low and mid 80s.

The next chance for rain should not come until Monday.

There is an added benefit to this weather pattern. While many factors affect fall foliage, a stretch of warm days, cool nights, and dry weather leading up to the turning of the leaves can be an important factor in contributing to vibrant colors.

Hopefully this pattern will set the stage for some great color in a couple weeks.
