From Grey to Blue

Wednesday is off to a cloudy and, for some, foggy start. That will not last as high pressure builds in and sunshine returns to the Finger Lakes.

Area of locally dense fog have formed across the region this morning. In areas where it is not foggy, skies remain overcast and grey.

The fog and cloud cover should start to dissipate during the mid and late morning hours. By the early afternoon, skies will start to turn sunny.

The second half of the day will be filled with sunshine and mild temperatures.

Look for afternoon highs to top out mostly in the mid 70s.

Temperatures overnight will drop back into the upper 40s and low 50s. Localized areas of fog will be possible again early Thursday morning.

Warming Up

Thursday will be similar to the second half of Wednesday, with bright sun-filled skies, light winds, and temperatures in the mid 70s.

Friday, too, will be quite sunny. A few high, thin clouds will pass through from the northwest, but these should not filter the sunshine much, if at all.

Temperatures Friday will get a bit of a boost from a west-southwest wind. Look for highs to be near or slightly above 80 degrees.

Saturday will be the warmest upcoming day. Some high thin clouds will again be possible but will have little impact on the warming effect of the sunshine.

Look for highs Saturday to push into the mid and upper 80s. With dewpoints pushing into the 60s, it will start to feel muggy out.

With the heat and humidity, a stray afternoon pop-up shower or storm cannot be ruled out, but there will be little going on in the atmosphere to trigger any action.

Storm Chances Increase Towards Memorial Day

Temperatures on Sunday and Monday will probably not get quite as warm as on Saturday.

However, there will still be plenty of warm, muggy air in place to prime the atmosphere for thunderstorm development.

Current projections show a couple of small disturbances aloft in or near the Finger Lakes which could serve as triggers for thunderstorm development.

The severe threat remains very questionable. While there will be plenty of fuel for the storms and some support for severe weather from the winds aloft, there are too many variables this far out to be sure of any threats.

Timing, location, areal coverage, and strength of storms are all significant question marks at this point.

Continue to monitor the forecast for the Memorial Day weekend.
