Looking Toward Friday
High pressure will pass by to our north today, bringing quiet, pleasant weather today as a proverbial calm before the storm.
The northern half of the region is starting off with sun this morning while thick clouds still blanket more southern areas. These clouds are associated with the stalled frontal boundary to the south and may prove to be hard to dislodge.
Still, even southern areas should see at least some breaks of sun this afternoon as the dry air associated with the high pressure erodes away at the overcast.
Winds will blow from the east-northeast today with speeds around or just over 5 mph.
The air will not be humid with dewpoints in the 50s to near 60 degrees. Afternoon highs will mainly stick to the mid 70s.
Skies will be mostly clear overnight with lows dropping to the upper 50s and low 60s.
Sunshine early Thursday will be replaced with clouds as moisture associated with Tropical Storm Debby begins to move north while a frontal system approached from the west.
Winds will turn to the southeast and increase to 10 mph. Dewpoints will rise into the 60s with highs in the mid 70s. A few rain showers will begin to show up during the second half of the afternoon, potentially with some brief downpours.
Rain will increase Thursday night, especially toward the predawn hours of Friday morning. Overnight lows will be in the mid and upper 60s with southeast winds persisting.
Friday will be a washout with steady rain likely throughout the day. As the low pressure center associated with the remains of Debby move near or directly overhead, a band of particularly heavy rain just west of the center will move through.
Gusty winds will also be possible along and east of the low pressure track, with gusts to 40 mph possible.
Unfortunately, it looks like Debby will make a direct hit on the Finger Lakes, with widespread rain amounts of 2-4 inches. Within the small but intense band of heavy rain, localized amounts of 6 inches are possible.
The Weather Prediction Center has our region in a Level 3 of 4 for flash flooding on Friday, and it seems very likely that numerous flooding events, some serious, will occur. The exact location of the highest risk is still unknown, but is most likely to occur somewhere within our region.
The rain will taper off quickly overnight Friday as a front moves through. By Saturday morning, the rain should be ended, but residual flooding may still be ongoing.
Staying Cooler
Saturday and Sunday are both looking quiet in the wake of Debby.
Saturday should start out with temperatures in the low 60s. Afternoon highs will make it into the mid 70s.
There should be a mix of sun and clouds. A stray spit of rain cannot be ruled out in the afternoon, especially near Lake Ontario.
Sunday will be similar, with sun and clouds and a stray lake induced shower possible. Morning lows will range through the 50s, and afternoon highs will be in the low to perhaps mid 70s.
The chances for a few showers will increase on Monday and Tuesday. Neither day looks overly active, though, and most areas will probably stay dry both days.
Temperatures will remain unchanged with lows in the 50s and highs in the mid 70s.
Random spits of rain will continue to be possible through the middle and end of next week. No major weather systems are expected though, giving the region a needed break.
Temperatures will slowly creep up, with upper 70s toward the middle of the week and perhaps reaching 80 degrees late in the week and next weekend.
Humidity levels will remain low throughout next week as well, with dewpoints mainly sticking to the 50s.
