Even as the last days of summer count down, temperatures will be more fitting for July or August this weekend in the northeastern United States.
Temperatures are forecast to trend upward for the last official days of summer this weekend.
Highs are projected to range from near 80 in northern New England to near 90 in the major Interstate-95 cities of the lower mid-Atlantic region on Saturday and Sunday.
It is conceivable that a long stretch of dry weather gripping the region may allow temperatures to climb into the 90s in some of the major cities, which could challenge daily record highs in some cases.
Many of the records late this week and this weekend were set during a vicious late-season heat wave that lasted many days 124 years ago in 1895. The records set during that period are in the middle 90s, which may be tough to match.
Nights this weekend into early next week will be cool, but the evenings will feel more like the middle of summer until after the sun goes down.
An area of high pressure will set up shop at most levels of the atmosphere in the Northeast promoting dry and mild weather into this weekend.

The same area of high pressure will help to protect the region from Humberto, which is spinning toward Bermuda.
As Humberto approaches Bermuda, AccuWeather forecasters continue to keep a close eye on a tropical disturbance located in the central Atlantic.
Initially, the high pressure area will bring down cool air.
"Before the heat builds, the pattern will bring cool nights and mornings with comfortably warm afternoons," according to AccuWeather Senior Meteorologist Dave Dombek.
Through Thursday, highs will generally range from the middle 60s across northern New England to near 80 around the lower part of the Chesapeake Bay. Nighttime lows will range from the middle 30s over northern Maine with a touch of frost to the upper 50s in southeastern Virginia.

Storms will tend to avoid much of the northeastern United States through this weekend.
"In some places, such as around New York City, it may not rain through Monday," Dombek said.
The pattern through this weekend will promote nearly ideal weather conditions for outdoor projects that may have been put off. This includes painting, driveway sealing, concrete work and harvesting crops. Some construction projects that may have fallen behind over the summer may get back on track.
Of course, the weather will be great for outdoor fun, such as golfing, fishing and ball games.
Remember if attending ball games during the afternoon hours to wear sunscreen and sunglasses. Short-sleeve and lightweight clothing may help you stay comfortable.
Despite the storm-free pattern, there will be some issues for travelers and beach goers.
For those heading to the beach, keep in mind that Hurricane Humberto will stir rough surf and strong rip currents while spinning hundreds of miles offshore.
These conditions will build in mid-Atlantic and New England waters during the middle and latter part of this week and may not improve until this weekend.
Because the nights are getting longer and the air has more time to cool to the saturation point, when compared to July, this means that fog is likely to form during at least some of the late-night and early-morning hours. The fog may not be limited to the river valleys and can be dense enough to impede driving and in some cases trigger airline delays.
Are there any big blasts of chilly air in sight?
There is some indication that the warmth may be less persistent during the last week of September.
"We should see a return of the back-and-forth warm and cool pattern over the northern third to half of the Central and Eastern states late in September," according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.
"However, there is no lock-on signal for persistent chilly weather or progressively colder conditions just yet," AccuWeather Senior Meteorologist Brett Anderson added.
As a result, it's possible temperatures may be no lower than average for the Northeast for the entire period as a whole from now through early October.
This means that except for the normally cold spots of northern New England and northern New York state, frost does not appear likely through the first part of October in the Northeast.
AccuWeather meteorologists will continue to monitor the weather conditions for any sign of rain or frost for your outdoor projects, gardening and crop concerns.
Autumn officially arrives at 3:50 a.m. EDT, on Monday, Sept. 23.
