A large area of high pressure in the upper atmosphere is building over the Northeast for the new week ahead – and in the summer, that usually means heat.
Underneath this area of high pressure, temperatures will be on the rise up to 10 degrees above average. That may not seem like much, but given it's the middle of July and average temperatures are around their maximum for the year, it means several days of sultry weather are ahead.
How High Will Temperatures Rise?
In general, it looks like temperatures will top out in the lower to mid 90s Monday through Thursday from Hartford, Conn. and Providence, R.I. to New York City, Philly, and Washington D.C. Heat index values at times may reach into the upper 90s to lower 100's.
For New York City and parts of southern New England, it appears this will qualify as a heat wave, which is three or more consecutive days with highs in the 90s in this region of the country. The Big Apple topped out at 90 degrees Sunday.
Farther to the north and across the interior Northeast, upper 80s and low 90s are expected in Boston, Burlington, Vt., Albany, N.Y. and Pittsburgh, Pa.
It won't be just the Northeast sweating through the week ahead. Parts of the Great Lakes and Ohio Valley will also see temperatures in the upper 80s and low 90s. This includes Chicago, Detroit and Cincinnati.
Hot Month Already
Thanks to a hot start to July, temperatures this month in the Northeast are already running several degrees above average.
In southern New England, the average temperature so far this month is five to six degrees above average in Boston, Hartford and Providence.
Farther south, the first 13 days of July have been three or four degrees above average in New York City, Newark and Philadelphia.
