Forecast Discussion:

A soaking rain will develop across the region starting tonight. Widespread rain will overspread the area from west to east around or just after midnight. The rain will fall heavy at times, especially early Sunday. It is safe to say that Sunday morning will be a total washout for all locations in the Southern Tier. The steady rain will taper to showers after 3 p.m. Sunday afternoon. Overall, 0.5-1" of rain is expected during this time frame.

In addition to the rain, temperatures will be cool on Sunday with highs maxing out near 50 degrees. There will also be a breezy southeast wind at 10-20 mph.

Scattered showers will stick around for Sunday night before a second round of rain arrives early Monday morning.

Monday looks to start off wet with widespread rain during the morning, tapering to scattered showers by mid afternoon. Temperatures will be unseasonably cool with highs in the upper 40s to low 50s.

Tuesday will likely be the driest day of the week under partly sunny skies.

The rest of the forecast isn't favorable for any outdoor activities. We will enter a prolonged stretch of clouds, showers and gloomy conditions. A storm system will meander around the northeast from Wednesday through the weekend. This will keep the clouds locked in place along with frequent rain showers, especially Thursday, Friday and Saturday. Temperatures during this period are expected to remain at or just below average-- near 60.
