Sunshine replaces showers, but won’t last long

Windy as Sunshine Returns

The weather across the Finger Lakes will slightly improve today, but it will only be a temporary change.

Low pressure is situated to the north, just across Lake Ontario this morning. Clouds and scattered showers are rotating around the low through the Finger Lakes.

Meanwhile, an area of high pressure over the Southeast extends north into the Upper Great Lakes and is shoving the low away.

There is a sharp cutoff between cloudy skies and sunshine over southern Ontario and western Pennsylvania. This clearing will steadily push east today. By the early afternoon, most of the region should be sunny.

The drawback to having the high literally push the low away will be a period of blustery west winds. Gusts could reach 40 mph during the midday and afternoon hours.

Temperatures will jump into the mid and upper 60s once the sunshine works out this afternoon.

Unsettled Father’s Day Weekend Weather…and Beyond

The high pressure system will move out over the Atlantic Ocean tonight and early Saturday, opening our region back up to an active weather pattern.

A frontal boundary will set up from eastern Canada, through the Great Lakes, and into the Midwest and Great Plains.

Showers will return as early as the overnight period tonight with a few showers linger into the early morning hours Saturday.

A break in the precipitation should settle in for the late morning and early afternoon. A bit of sunshine will be possible in this time, boosting temperatures into the low 70s.

Scattered showers will pop up again during the second half of the afternoon and may transition into a more widespread evening rain. A couple heavier downpours and a rumble of thunder or two will also be possible through the overnight. Some areas could see between a half-inch and one inch of new rainfall Saturday night.

The evolution of the rain chances for Sunday remain uncertain. As subtle disturbances move along the front, rain chances will increase. However, resolving these small systems is difficult for the weather models more than a day or so in advance.

In a worst-case scenario for Father’s Day, another batch of widespread rain with embedded downpours will move through during the afternoon hours. In a best-case scenario, most of the activity stays south and we only have to contend with a stray shower here and there.

Temperatures Sunday will of course depend largely on how much rain is or isn’t falling throughout the day.

Unfortunately, this pattern will hold for most of the upcoming week. It will not necessarily rain every day, but the number of wet days should outnumber the dry. Most of the systems rolling through during the next week are also small and weak which keeps confidence in the day to day weather low. Stay tuned.
