The Weather Service issued a flood watch effective from 6 p.m. through late Tuesday night for the entire state, except for the Cape and Islands.

This afternoon showers will give way to heavy rain between 5 p.m. and 8 p.m. that will continue through the night. At times, one inch of rain may fall per hour, the forecasters said.

The rain will taper off Tuesday morning, but showers and thunderstorms could return Tuesday afternoon.

Overall 1 to 2.5 inches of rain is expected to fall through Tuesday evening.

“This may result in significant urban flooding,” the Weather Service said, “as well as flooding of rivers and streams.”

The forecasters urged people in flood-prone areas to protect items that could be damaged by rising waters and have a safe place to go if flooding happens. They also advised people that roads may be closed due to flooding.

Tuesday will be cool and damp as the mercury won’t top 65 degrees in Boston.

Once this system moves out of the region Wednesday, with only a chance of showers and thunderstorms remaining, conditions should improve as temperatures reach 80 in Boston.

We’ll be able to see clearly once the rain is gone Thursday and Friday, as skies clear and temperatures reach the low 70s.

Downpours on Friday caused flooding from Fall River to Billerica, and the Weather Service said that a record 3.07 inches of rain had fallen at Logan International Airport on Friday. The previous record for June 7 was 2.89 inches, set in 2006.

The rainfall also broke records in Worcester and Providence. The highest rainfall in the state during the 24 hours starting late Friday morning was 5.4 inches, recorded in Hudson, the Globe reported Saturday.
