Final mild day before cold front brings widespread rain and cooler temperatures

Needed Rainfall

A strong cold front will bring an end to our warm, sunny weather, but not before one final day of mild temperatures.

This front is draped from a low pressure just north of the Great Lakes, south through the Great Lakes, Ohio Valley, and into the Gulf States. Out ahead of this front, a small disturbance is riding north along the Eastern Seaboard.

The small disturbance could trigger a few scattered showers. Most areas will probably stay dry, though, and there should be plenty of sunshine mixing with the clouds.

As the front slowly presses eastward, warm air will remain in place over the Finger Lakes on the back of south winds. Wind speeds will be similar to the breeziness of the weekend, with gusts of 25-30 mph.

High temperatures will range from the low 80s in the north to the upper 70s across the south.

Winds will remain blustery through the overnight with temperatures staying in the mid and upper 60s. Between about 5-9 AM, the cold front will move through with a band of showers and a quick drop to around or just below 60 degrees.

A few scattered showers will linger for the midday and first part of the afternoon. If a little sunshine works its way through the clouds, temperatures may bounce back into the low and mid 60s.

Late in the afternoon, low pressure will ride north along the front and rain will become widespread and steady, lasting through the night.

Most areas along and east of a Canandaigua-Dansville-Wellsville line should see at least a half-inch of rain. Some areas that are considered in a moderate drought in the southern and southeastern Finger Lakes could see an inch or more of rain.

The rain will taper off from west to east early Wednesday morning, though a few showers will linger.

Cool Pattern

Behind the rain, Wednesday afternoon should turn partly cloudy with highs reaching into the mid 60s.

Thursday will also be partly cloudy with highs mostly in the low 60s. A few stray showers off Lake Erie could be possible in the western Southern Tier.

Quiet conditions Thursday night will allow temperatures to drop back into the mid 40s, though some pockets will likely get colder. Frost is not expected, though.

Another weather system will swing through on Friday with scattered rain showers. A few lake effect showers will linger into Friday night near the shores of Lake Ontario and Lake Erie. Most of the Finger Lakes should turn partly cloudy, though.

Low temperatures Saturday morning will range from the upper 30s in the Southern Tier through the 40s further north.

A few more showers will be possible on Saturday as another piece of atmospheric energy moves through. Highs will only be in the low 50s thanks to the clouds and showers.

Sunday looks dry with highs bouncing back to around 60 degrees. Temperatures will remain in this neighborhood through most of next week. There will be more chances for rain next week, most likely coming on Tuesday.
