Sunny and Warm
High pressure remains overhead as it sprawls across the eastern half of the United States.
This high will continue to deliver sunny, very warm weather before the pattern starts to break down late this week, then completely collapses this weekend.
Skies are clear for most of the Finger Lakes again this morning, with just a few patches of fog and low clouds. These will quickly burn off by mid-morning, leaving blue skies and sunshine for the rest of the day.
Winds will be light again today as well, going from mainly calm this morning to gentle from the north this afternoon.
Temperatures will add a few more degrees onto the highs with many areas getting to or above 80 degrees. Only higher elevations will end up just short of 80 degrees.
Skies will remain clear tonight, with evening temperatures in the low and mid 60s and overnight lows between 55-60 degrees.
Wednesday will be more of the same, only with light south winds as the high pressure system drifts off the Mid-Atlantic coast.
The south winds will give the northern tier of the Finger Lakes a boost into the mid 80s, especially along and north of I-90 and in the Genesee Valley. A few locations in the broad valleys of the Southern Tier may also sneak towards the mid 80s.
Most of the rest of the region should have temperatures just a degree or two warmer than today, at or just above 80 degrees.
Wednesday night will be warm with lows averaging out around 60 degrees. Some clouds will start to move in after midnight but should remain thin at first. Thin clouds will persist into Thursday morning but will gradually become thicker as the day goes on.
The loss of the full sunshine will knock temperatures back a bit with highs mostly in the upper 70s.
Friday will remain mild as well with highs well into the 70s. However, a slow moving cold front will start to move in and at least some rain showers should start to arrive before sunset.
Rain will increase Friday night as the front continues to creep eastward. By Saturday morning, the front should be overhead, where it may stall out as low pressure rides north along the front. Widespread rain is likely on Saturday, some of which may be heavy and long lasting. As things stand now, Saturday looks to be a washout.
Temperatures will not recover on Saturday. After starting in the low 50s, afternoon highs will struggle to reach the upper 50s. Later in the day, west and southwest winds will increase behind the front.
Clouds and showers will continue Saturday night and into Sunday. Again, the rain may continue to be widespread and long-lasting but should be lighter than Saturday’s. Southwest winds will increase, with gusts over 30 mph likely.
Sunday will be the coldest day yet this season, with highs struggling to even get above 50 degrees. Despite continuing clouds and showers, temperatures Sunday night will drop to the upper 30s and low 40s.
Monday will be showery, but less so than Sunday. It will remain cold and breezy with highs around 50 degrees.
Showers, enhanced by Lake Ontario, may linger well into next week until temperatures slowly trend back toward average values. High temperatures may not make it back into the 60s until Thursday or Friday.
