Flooding threat persists in Finger Lakes Friday afternoon

Friday Flash Flood Potential

The Finger Lakes region is once more under the gun for flash flooding this afternoon as yet another round of rain and thunder move through the region.

Showers and thunderstorms are expected to develop over the Finger Lakes during the early afternoon hours, roughly along a line from Oswego to Canadaigua to Dansville to Olean.

The flash flood threat will be greatest to the east of this line as storms strengthen and track eastward. Further west, the flooding threat is minimal with just some scattered showers and lighter thunderstorms.

The flash flood threat will be elevated for areas that had torrential rain yesterday and Wednesday night. This includes places such as Penn Yan, Geneva, and Moravia, which continues to be hit hard time and time again this year.

For other areas in the eastern Finger Lakes that have not seen quite as much rain (less than 3 inches), the flood potential is set at low, which is a step below the more soaked areas. The threat yesterday was elevated to high.

I incorporated both the chances for thunderstorms and recent rainfall amounts in setting the threat levels today to really specify which areas were most at risk.

The thunderstorms today should not be as widespread as they were on Thursday, but the heaviest could have similarly torrential downpours. There is also a minimal threat for some strong winds.

Many areas in the eastern 2/3rds of the Finger Lakes will see additional rain today. Probably only a few areas will see the same level of rain as on Thursday.

Thunderstorms should rumble east by dinner time, with just some scattered showers and lighter storms lingering into the evening.

Weekend Weather Looking Better, But Not Perfect

Today’s showers and storms will be triggered by an area of low pressure moving along the frontal boundary that has been draped over the area much of the week.

This low will finally give the front the kick it needs and will remove it from our area.

Less humid air will work in behind the low on northwest winds. Before the dry air completely arrives though, a few scattered rain showers will persist into Saturday morning. By the afternoon hours though, the sun should be shining.

Look for highs on Saturday to be in the mid 70s with noticably lower humidity levels and a fresh breeze.

Sunday will start out sunny and dry with temperatures warming quickly from the low 60s in the morning. Some low 80s will show up by the afternoon.

Also showing up will be some scattered showers and thunderstorms, particularly over the more western portions of the region. These showers and storms will track east during the evening and overnight hours with rain and thunderstorms likely on Monday.

Thankfully, even though more rain is not good news, the atmosphere will not be as primed for the type of torrential rains we have seen, so the flood threat should hopefully remain minor.
