Saturday Update

A complex weather setup is beginning to reveal itself this morning over the Finger Lakes as low pressure brings a cold front into the area.

Complicating the picture is leftover rain and thunderstorms from activity that developed yesterday over the Midwest and Great Lakes. Now that Saturday morning is here and the set up is unfolding, here are some pertinent updates for today.

  • Some thunderstorms are already ongoing near and north of I-90 this morning. These areas may see several rounds of thunderstorms before noon.
  • Rain and thunderstorms will increase region-wide during the late morning and early afternoon along the front, and will progress towards the east through the mid-afternoon.
  • From roughly Corning to Auburn and points eastward, the precipitation may be delayed enough to allow the atmosphere time to prime itself for some isolated severe thunderstorms during the early to mid-afternoon. Damaging winds will be the primary threat.
  • A flood watch is in effect for the northern and northwestern Finger Lakes, including the following counties: Cayuga (northern), Genesee, Livingston, Monroe, Ontario, Wayne, and Wyoming. Repeated thunderstorms in these areas may bring pockets of flash flooding. Isolated flooding outside of these areas will also be possible.
  • Most of the rain should be out of the Finger Lakes region before 5 PM, though isolated showers will linger into the evening hours.
