Heat Arrives Today, Humidity Tomorrow

A large area of high pressure has taken up residence just off the coast of North Carolina.

Meanwhile, an area of low pressure over the Plains will merge with the remains of Tropical Storm Cristobal as both move north towards the Midwest.

Both of these factors result in a broad southerly flow across the eastern United States, leading to an increase in temperatures and humidity.

The temperatures will come up before the humidity does, with a hot but dry day today.

Highs will push into the mid and upper 80s, and a few places may reach 90 degrees. With dewpoints only in the 50s, it will not be a muggy heat. There will be few clouds and little wind for relief though.

Some thin clouds will work in overnight and south winds will increase. Dewpoints will rise into the 60s overnight, keeping temperatures in the mid 60s.

Wednesday will see temperatures quickly warm as the south winds become blustery. Gusts could hit 30 mph.

Dewpoints will continue to rise to around 70 degrees, making it feel very muggy. Temperatures will push into the upper 80s and low 90s.

There is a small chance for an isolated afternoon thunderstorm, especially across the Southern Tier. Any storm that pops will have a chance for frequent lightning and strong winds. Most areas should not see any rain, though.

A cold front will move through overnight. Some thunder will be possible, especially over Western New York, but the front should be late enough in the night that the thunderstorms should be weakening. Eastern areas may see little to no rain.

There are still some uncertainties with the rain chances, though, so be sure to check back tomorrow morning.

Temperatures Retreat

Wednesday night will be very warm with most areas staying in the low and mid 70s into Thursday morning.

Less humid and slightly cooler air will work in during the day, though. Temperatures will top out around 80 degrees as dewpoints fall back into the 50s.

West and southwest winds will gust between 30-40 mph on Thursday. Morning clouds will give way to afternoon sunshine.

Sunshine is likely on Friday before an increase in clouds Saturday and perhaps a few showers on Sunday.

Temperatures will continue to retreat, though the weekend will be much cooler than Friday.

Friday will have highs in the mid 70s, while Saturday and Sunday only reach the mid 60s. Lows Saturday and Sunday will be between 45-50 degrees.

Next week, temperatures will slowly increase, spending most of the week in the 70s. Rain showers will be possible next week, but it is too early to pinpoint when.
