Turning Hotter

Friday will be another warm day in the Finger Lakes as the temperature continues to rise beneath high pressure.

Temperatures are starting on the cooler side of things again this morning but will be able to rise in a hurry this morning, even with some of the sunshine getting filtered by high, thin clouds.

These clouds are on the edge of some thunderstorms over Michigan associated with a weather system that will arrive in our area on Saturday.

The cloud cover should lessen some this afternoon and no precipitationĀ is expected today.

Temperatures will range mostly through the upper 80s to near 90 degrees with some of the typically warmer areas getting just above 90 degrees.

Humidity will still be quite low with dewpoints in the 50s.

Temperatures will not be so cool tonight with overnight lows in the remaining in the upper 60s.

Saturday’s Storm Chance

The aforementioned weather disturbance will slowly drift southeast towards the Finger Lakes, finally arriving in our area for Saturday.

Skies will start the day mixed with some clouds and some sun. A brief shower may also be possible.

Temperatures will warm into the mid or upper 80s for the afternoon, which will provide a little fuel for some thunderstorm development.

Unfortunately, the best chance for thunderstorms may end up just south of the Finger Lakes, closer to the NY/PA state line. As I pointed out in yesterday’s drought report, these areas have seen more rain this summer and are not classified as being in the pre-drought phase, while the rest of the Finger Lakes is.

Still, a stray storm may be possible in the Finger Lakes itself, especially for more southern areas. One or two storms could briefly become robust with some strong wind gusts.

Heat Breaks Tuesday

Sunday and Monday will continue to have warm and increasingly humid weather.

Both days will have a minute chance for a shower or thunderstorm during the afternoon, but the majority of the region will not see any rain either day.

Temperatures Sunday will be a touch cooler than on Monday, with mid and upper 80s being replaced by low 90s.

A cold front will then approach the region on Tuesday. This system looks to be the most robust weather system we have seen in several weeks, but the timing of the front will determine what type of weather we see.

Even if the front passes early in the day, there will be a chance for some heavy thunderstorms. An afternoon frontal passage could mean more robust action. This is still several days away, so there is plenty of time to work out the details.

Temperatures behind the front look to be closer to normal, at least for a few days if not longer.
