Active Pattern Yields Little Precipitation

A broad area of low pressure is moving into the Upper Great Lakes while a train of small disturbances is passing to our southeast.

This set up will bring us a cloudy, breezy, and increasingly humid day, but with little to no rain to show for it.

Most of the region is starting out cloudy, though there are a few breaks in the clouds. As the morning goes on, the clouds should thicken further. Overcast skies will continue into the afternoon.

Rain is generally not expected though, with just a few drips here and there on occasion.

South winds will blow at 10-15 mph with gusts of 25-30 mph. These winds will bring in some extra humidity, with dewpoints rising to the low 60s. Afternoon high temperatures will be similar to yesterday with most areas in the mid to upper 70s.

The clouds and wind will continue overnight, keeping temperatures in the 65-70 degree range. The chances for a shower will creep up slightly after midnight.

Sunshine will again be limited on Wednesday as the Great Lakes low tracks northeast into Canada. A few late morning or early afternoon showers will be possible as a disturbance passes through, but the best chance for rain will be late in the day.

A cold front will press through the region during the late afternoon and early evening, triggering some showers and thunderstorms. Even if most of the region ends up seeing some rain, amounts will likely be under a quarter inch for most. Severe storms are not expected.

Otherwise, Wednesday will continue to be breezy with south winds gusting over 30 mph, especially during the morning. High temperatures will be in the 70s for higher elevations, but low to mid 80s from Elmira to Rochester to Syracuse.

Quiet and Cooler into the Weekend

Some sunshine will return on Thursday as it darts in and out of some clouds. Clouds will increase for the afternoon as a disturbance rides along Wednesday’s front, which will be located along the Mid-Atlantic and New England coast.

A few showers from that disturbance may clip areas such as Elmira, Ithaca, and Cortland by Thursday evening, but they should be long gone by Friday morning as high pressure builds in.

Friday and Saturday should have ample sunshine, and even Sunday should at least start out sunny.

High temperatures on Thursday may still sneak into the 80s for the typically warmer lower elevations of the central and northern Finger Lakes. Higher elevations should be in the mid and upper 70s.

Friday will lose several degrees with the warmest areas near or just above 75 degrees, and higher elevations just getting above 70 degrees.

After several nights with lows in the 60s, Friday night will drop well into the 50s. A few valleys in the Southern Tier could reach the upper 40s.

Highs on Saturday will be a couple degrees cooler still, with upper 60s in the higher elevations ranging to the low and mid 70s elsewhere.

An incoming weather system on Sunday will bring temperatures back up to the upper 70s and low 80s. Rain currently looks like it will hold off until Sunday night or Monday, with another period of cooler temperatures behind it for early next week.
