Low pressure continues to organize over the Ohio Valley and track northeastward. Some high clouds ahead of this storm will overspread our area tonight, but those clouds will be thin, so temperatures will still be cool and comfortable.
There may be a few hints of sun Friday morning, before the clouds thicken up over CNY. While the heaviest and steadiest rain should end up west of our area, we expect a few showers to impact us during the day Friday, especially during the afternoon. The pressure difference between the storm mentioned above and high pressure to the east of New York State, will create a southeast wind over us. Over higher elevations, the north ends of the Finger Lakes and the Mohawk Valley, east-southeast winds of 15-25 mph are likely through the day Friday. With the heavier rain holding off until later in the day, temperatures should be able to warm into the mid 70s.
The rain should get heavier Friday night, along with a few rumbles of thunder. Rainfall amounts could approach an inch over parts of the area by the time things are winding down Saturday morning. Following the rain, most of CNY will likely lie in an oasis of relatively quiet weather as our surface storm moves off to the northeast and an upper low remains to our west. While, spotty showers are possible Saturday, much of the daylight hours will be dry. Eventually the upper low will move overhead and slow down. Consequently, the threat for scattered showers (mainly fueled by daytime heating) and thunderstorms will increase Sunday. The upper low will be slow to move meaning cool and unsettled weather may persist into early next week.
