Heat Advisories
For the second day in a row, Heat Advisories are in place across the Finger Lakes.
High pressure to our south continues to keep our region devoid of any precipitation while also providing a steady supply of heat and humidity.
Overall, today will be a couple of degrees hotter than yesterday, and then tomorrow will eclipse today by another degree or two.
Many places will be in the upper 80s to low 90s today. With dewpoints between 65-70 degrees, this will send heat indices ranging through the 90s.
Clouds will be limited to some upper level clouds this morning and some fair weather clouds this afternoon. None of the clouds should do much to block the sunshine or reduce temperatures.
Winds will be light with speeds mainly under 5 mph. What little wind there is will come from the north and northwest, produced by Lake Ontario.
Skies will clear tonight with warm and muggy conditions persisting. Overnight lows will mostly be in the mid and upper 60s.
Wednesday will turn out very similar to today, with plenty of sunshine, heat, and humidity. More areas will be at or above 90 degrees, and a few of the warmer pockets of the region could sneak into the mid 90s.
Dewpoints will remain high, sending heat indices to near 100 in some areas. Another Heat Advisory will be needed for tomorrow.
The pattern will start to erode Wednesday evening as some showers and thunderstorms move into far western areas. These are not expected to make it east of Canandaigua Lake before dissipating overnight.
However, their presence will mark a further increase in humidity, with dewpoints rising to the upper 60s and low 70s overnight. Low temperatures will be close to those muggy dewpoints as well.
Turning Stormy
Thursday morning should remain dry with temperatures quickly pushing towards the 80s. However, widespread showers and thunderstorms are then expected to develop during the afternoon, capping the rising temperatures in the mid and upper 80s.
While there is not much wind support in the atmosphere, the heat and humidity may contribute to some localized strong to severe storms with strong winds. Frequent lightning and heavy downpours will also be possible. These will continue into Thursday evening.
Rain amounts on Thursday will vary greatly across the region, and a few pockets may end up with little to no rainfall. Most areas, however, should see at least some rain.
Friday will be more of the same with showers and storms, especially in the afternoon. Temperatures will have an even smaller window of opportunity on Friday and should peak in the low 80s. It will remain excessively humid with dewpoints around 70 degrees.
There will be more in the way of wind in the atmosphere on Friday, which could lead to a greater severe risk than on Thursday. This is far from certain, though, so continue to monitor the forecast.
Saturday and Sunday will see continued showers but with a decrease in thunderstorms. Temperatures will continue to fall, with highs in the mid 70s on Saturday and low 70s on Sunday.
Both days this weekend will have rain at almost any time, so it may not end up being great for outdoor activities. Again, continue to monitor the forecast for updates.
Cool, unsettled weather will stick around throughout next week. It will probably not rain consistently every day, but the mid-week especially looks to have a high chance for rain.
Temperatures will stick to the 60s and low 70s for highs next week. With plenty of clouds, nighttime temperatures will remain in the 50s with little chance for anything colder.
