Temps should get into the upper 70s and low 80s head of the front, but as it moves in, expect a good chance for showers and thunderstorms.
Another storm system is expected to move in Friday and Saturday.
There are a lot of shower and storm chances for the week ahead. Today's high will be 87 with a south southwest wind of 5 to 11 miles per hour, and new rainfall amounts between a tenth and quarter of an inch.
Meteorologist John Homenuk of New York Metroweather said severe thunderstorms and potentially strong wind gusts, large hail, unsafe lightning and "even a tornado or two" could develop later in the day in Pennsylvania and Southern New York. At 1:20 a.m. Friday, the Central Nebraska Regional Airport in Grand Island reported a peak wind speed of 64 miles per hour.
"Scattered severe thunderstorms with damaging wind gusts and large hail are possible this afternoon and evening", NWS said in a Hazardous Weather Outlook statement.
One final round of storms is possible after midnight, the weather service said. The main threat is damaging, straight-line wind (30 percent chance), possibly from a squall line moving out of Ohio/West Virginia. Some threat may extend downstream out of the watch into northern IN/southwest MI, but no watch issuance is expected in that area at this time. Highs Tuesday are forecast in the low to mid 80's.
