High Pressure
A small area of high pressure is building into the area behind the front that brought the rain and thunderstorms to the Finger Lakes yesterday.
Cooler air associated with the high pressure system moved in last night and has some areas off to a foggy start this morning. The fog, and some lingering low clouds, may take a bit of time to erode away. Areas that are not seeing any fog or residual cloudiness are sunny and will stay that way through the day.
Eventually, all the region will enjoy mostly sunny skies. Only a few small fair weather clouds here and there are expected, and no rain will fall.
Comfortable dewpoints in the mid 50s will be commonplace today and highs will top out in the mid 70s. Only a whisper of an easterly wind will blow with speeds under 5 mph.
The wind will turn to the southeast tonight and pick up a little speed. This will allow moisture to increase, both in the form of dewpoints and some clouds. Temperatures will reach their nighttime minimum around midnight in the low 60s. From there, temperatures will rise a couple degrees by dawn Friday.
While cloud cover will increase for Friday, some sun will probably poke through the clouds from time to time. A few isolated brief showers may pop up for the afternoon, but it will be far from a washout.
Dewpoints will be back into the mid 60s and highs will mostly be in the upper 70s and low 80s.
Weekend Weather & Next Week
There will be a better chance for scattered showers and perhaps a couple thunderstorms on Saturday as a front moves into the region.
Again, though, it should not be a washout of a day. The rain that falls will remain scattered. While most areas may end up seeing some rain, heavy or long-lasting rain is generally not expected.
High temperatures on Saturday will be held in check by the rain and clouds but should still reach the mid 70s. It will remain muggy with dewpoints in the mid and upper 60s.
A second front will slide through Saturday night with an isolated shower and a shift in the winds to the north. This will send dewpoints to near 50 on Sunday, with highs around 70 degrees. Like today, only a few stray clouds are expected, if even that.
Monday will be similar, but warmer. Start to finish sunshine is expected with highs ranging through the 70s. Most areas will be in the mid 70s.
Tuesday also looks dry and sunny, though a few more thin clouds and fair weather clouds are expected. Temperatures and humidity will increase, with highs in the upper 70s and low 80s and dewpoints reaching the low 60s.
Clouds will increase on Wednesday and some rain showers could even start to move in from the west late in the day. A strong front will cross the area Wednesday night into Thursday, possibly bringing some heavy rain. The timing and strength of the front are, of course, uncertain this far in advance.
Regardless of the timing and precipitation, this front looks like it will put an end to the mild September weather. Highs behind the front for late next week and into the final days of the month look to mostly be in the 60s with 40s and 50s for overnight lows.
