Most areas will not see rain Friday or Saturday as temperatures soar.
Temperatures today will be a couple of degrees warmer than they were on Thursday. For the southern half of the Finger Lakes, this means mostly mid 80s, while the northern Finger Lakes, and urban areas, reach the upper 80s.
It will be noticeably more humid though, with dew points well into the 60s. The heat index will rise to 90 degrees in some areas a result.
Precipitation will be quite limited today. Yesterday’s rain and thunder focused across the western parts of the region. Today, the focus will be near the New York/Pennsylvania line and into the far eastern Finger Lakes.
The trigger for today’s showers and storms is a weak disturbance situated southeast of Cleveland this morning. This disturbance is weaker than a second one further east over Pennsylvania, which already has a few light showers with it.
Because it will be hot and humid, even this weak disturbance should be able to touch off a few showers and storms. Winds in the atmosphere are light, which is just one of a number of variables detrimental to storm growth and duration today.
As a result, any storms that do form may only last an hour or two before dissipating, and the general coverage of the storms will be widely scattered. Any storms that linger into the evening will quickly dissipate by 7 or 8pm as the atmosphere cools.
Overnight lows will drop into the low and mid 60s, but sunny skies will warm temperatures very fast Saturday morning. By midday, most areas will be well into the 80s. Highs Saturday will top out near 90 degrees for much of the northern Finger Lakes, and even some of the urban areas across the southern FLX. Elsewhere, the temperature will fall just shy of 90 degrees.
It will be even more humid on Saturday. This will push the heat index into the mid 90s. Remember to be smart and safe in this high heat, and to check on the elderly. Keep your pets safe and cool, too.
At this time, there does not look to be anything to trigger showers and storms Saturday afternoon. With as hot and humid as it will be though, one or two storms could still briefly pop up, especially closer to Lake Ontario along the lake breeze.
Showers and storms will become much more numerous on Sunday afternoon and into parts of Monday. Neither day looks like a total wash out, but most areas will probably see at least some precipitation during that time. Temperatures Sunday will be similar or just a bit warmer than today, with highs near 80 on Memorial Day. Warm weather continues into next week.
