Quick Sunday Updates
The weather has held out quietly this morning, but rain chances will slowly increase over the next 12 hours.
A stalled out front to the north, plenty of atmospheric moisture, and a slow moving low pressure system will combine to bring rain into the Finger Lakes.
The rain chances will gradually increase this afternoon across the southern half of the region in the form of showers and thunderstorms. This evening and overnight, the rain will spread north into the rest of the area. Rain will continue through Monday morning, though there may be some occasional breaks. Lightning will be less common overnight into Monday, but localized downpours will continue.
Less certain is how Monday afternoon will play out as the front sinks southward. The rain will gradually end from northwest to southeast, but how quickly it does so remains to be seen. A washout of an afternoon remains possible, but not a guarantee, especially in the southeastern quadrant of the region (roughly speaking from central Seneca County south and eastward.
The axis of the heaviest rainfall, on the order of 2-4 inches, will stay just south of the area across northern Pennsylvania. Some parts of the Southern Tier could sneak above two inches, in addition to some localized pockets due to downpours.
I will have my normal weekday morning blog post tomorrow around 8 AM.
