Storm System Approaches

Friday is off to a cloudy start as moisture left behind by last night’s cold front is trapped beneath an incoming high pressure system.

The clouds will gradually erode away this morning as dry air works into the region. A few areas may stay cloudy into the midday hours. Sunshine will win out by the afternoon, though.

With high pressure moving in from the west and yesterday’s cold front pressing east, our winds today will be from the north, albeit at light speeds.

The north wind will keep areas close to the shore of Lake Ontario cool with highs in the mid and upper 40s. The remainder of the Finger Lakes should be near or just above 50 degrees.

Temperatures will take a quick dive into the 30s this evening before the freefall is halted be incoming clouds and a southeast breeze. There may even be a couple degrees of warming before dawn Saturday.

Saturday continues to be a tricky day to nail down the details for.

A warm front will slowly move northeast toward the region. Rain out ahead of the front will arrive sometime in the early or mid afternoon hours, spreading from south to north. At first, the rain may not reach the ground.

Temperatures will depend on how this process unfolds. Once the rain starts trying to fall, temperatures will cool due to the evaporation. Right now, the best chance for 50 degree temperatures is north of I-90 and especially east of about Geneva.

The heaviest rain will move in during Saturday night. The warm front will move through with a few thundery downpours possible. Many places should see over a half-inch of rain Saturday afternoon and Saturday night, and some localized amounts of an inch or more are possible.

Once the front moves through, south and southwest winds will increase. Top gusts will come Sunday during the day, clocking in around 45 mph.

Warm air will surge northward on Sunday, but may not completely penetrate the Finger Lakes. Areas west of Seneca Lake should push into the 60s or even hit 70 degrees, while areas to the east are more likely to see 50s.

Showers will continue through the day with a chance for scattered thunderstorms as well. The best chance for thunderstorms will be in the afternoon as the cold front moves through.

Temperatures Reset

Behind the cold front, temperatures will fall back into the 40s Sunday night. Cloud cover and continued showers should keep temperatures from dropping into the 30s.

Monday will be a cloudy day with on and off showers. The chances for rain will be greater the farther northeast you are in the region.

Winds will be from the west, bringing in cool, but not overly cold air. Temperatures Monday will not move much as a result, with highs in the mid 40s.

Clouds and a few showers will linger into Tuesday as well. Temperatures will remain stagnant, with lows in the mid and upper 30s and highs in the low and mid 40s.

By Wednesday, a new weather system will be passing to our south. At this time, it looks like precipitation will be limited to some drizzle and light rain showers. It will be another day of morning lows in the in mid and upper 30s and afternoon highs in the low and mid 40s.

Finally, by Thursday, sunshine should return to the area as high pressure builds in behind Wednesday’s system. Lows will start close to 30 degrees and afternoon highs should reach the upper 40s to near 50.

Quiet weather is expected Friday and Saturday as temperatures start to increase. A cold front will be possible Sunday, boosting temperatures further before it passes through.
