After a cool July 4th, sunshine and warmer temperatures are forecast, but Tropical Storm Elsa looms

After the coolest July 4th in 29 years, look forward to more seasonable temperatures this week but also the possibility of heavy rain from a tropical storm, according to the National Weather Service.

Sunday’s high of 68 made it the coolest Independence Day in Boston since 1992, when the temperature was 62, meteorologist Kristie Smith said. The coolest Fourth of July on record in the city was in 1978, when it was just 60.

Monday is expected to be “much more pleasant,” Smith said, with sunshine and a high in the upper 70s but also with a chance of afternoon showers.

Tuesday’s and Wednesday’s temperatures will make a sharp turn upward, with highs close to 90 and the chance of a thunderstorm, she said.

The highs on Thursday and Friday are expected to dip to the upper 70s to low 80s, Smith said, and Tropical Storm Elsa, which was over Jamaica and Cuba on Sunday, could move northward, bringing heavy rain to the Boston area.

“There’s just a lot of uncertainty,” she said. “The greatest impact we see is heavy precipitation.”

Cuba evacuated 180,000 people amid fears Sunday that Elsa could cause heavy flooding after battering several Caribbean islands, killing at least three people.

The Cuban government opened shelters and moved to protect sugarcane and cocoa crops ahead of the storm. Hundreds living in mountainous areas took refuge in natural caves prepared for the emergency.

The storm’s next target was Florida, where Gov. Ron DeSantis declared a state of emergency in 15 counties, including Miami-Dade County, where a high-rise condominium building in Surfside collapsed last week. Florida officials have warned that winds could hamper search-and-rescue operations there.
