The week will start off hot and may get hotter as the days pass, before rain impacts from Hurricane Beryl are felt across the region, according to the National Weather Service.

The Boston region will be placed under a heat advisory as of Monday at noon, NWS Meteorologist Kyle Pederson told the Herald, and though it’s currently slated to end Tuesday at 8 p.m., the advisory may extend through Wednesday.

“The heat index is going to get into the upper 90s, especially in the suburbs of Boston,” from Monday through Wednesday, Pederson said, and “Wednesday looks the hottest of the three for the heat index.”

“Boston itself will be a little cooler since it’s right on the water, but you go a few miles inland and It’s going to be hot,” he said.

According to the heat advisory, it will be dangerously hot in southern Worcester, central Middlesex, western Norfolk, northern Bristol, and western Plymouth counties, as well as parts of Rhode Island and Connecticut.

The weather service warns the weather conditions “may cause heat illnesses.”

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the advisory reads, in part.

Monday will be hot and humid, Pederson said, with high temperatures in the low 90s expected under mostly sunny conditions. NWS forecasts are calling for patchy fog before 7 a.m. on Monday morning, and more fog early morning on Tuesday.

Temperatures on Tuesday will climb further, into the mid-90s, with similar humid conditions and mostly sunny skies.

Wednesday it could hit 97 degrees, Pederson predicts.

Thursday could bring some relief from the heat, with temperatures forecast in the middle 80s, but it could also bring the first scattered effects of Tropical Storm Beryl, which is expected to return to hurricane strength before its Monday morning landfall in Texas’ gulf region.

“That moisture left over from Beryl could come up this direction and we could see some heavier rain later this week. Details are still fuzzy, but we’re looking like a Thursday-Friday-Saturday time frame,” Pederson said.

NWS shows the chance of rain on Thursday at 40% and that the day will otherwise be mostly sunny.

More rain is possible Friday and Saturday — a 30% and 40% chance, respectively, according to NWS — with temperatures again climbing toward the 90-degree range. Sunday currently shows as mostly sunny with high temperatures near 90 degrees.

NEW YORK (AP) – Amtrak rail service between New York and Boston was restored after a lightning strike was believed to have caused a circuit breaker to malfunction, the rail service announced Saturday night.

The malfunction caused a power outage on all tracks between Penn Station in New York and Union Station in New Haven, Connecticut, beginning Saturday afternoon.

Amtrak announced the service had been restored in a statement posted on its website.

Evening trains between Boston and Virginia were operating on schedule Saturday. Most trains were expected to be on schedule Sunday, although some Sunday train services were cancelled and others were expected to operate on a modified schedule, the company said.

Customers with reservations on affected trains would be accommodated on trains with similar departure times or on other days, the rail service said Saturday.

Amtrak said it would waive additional charges for customers attempting to change reservations.
