Today’s warm temperatures and high winds may feel nice, but they’ve also created conditions for fires to start and spread.

Thanks to gusty winds between 30 and 40 miles per hour and low humidities, the National Weather Service issued a hazardous weather outlook for the entire state, warning of fire weather conditions lasting through tonight.

Throughout the state, highs are expected to reach 80 degrees, meteorologist Bill Simpson said. The air will be dry, too, with dewpoints only in the 20s.

Though much of the region’s foliage has bloomed, reducing the risk of fire, hilly, higher terrain in areas like Worcester and the Blue Hills haven’t yet greened up, leaving them more vulnerable to the spread of fires, Simpson said.

“Usually, two ingredients for fires to spread are very low humidity and windiness,” Simpson said. The spring “green-up” can limit the spread of fires, though, he said.

In Boston, it’ll be the nicest day of the week, Simpson said.

Don’t worry about the wind ruining outdoor plans tonight—the winds should die down this evening around 6 p.m., Simpson said.

A mild night will give way to another nice day Friday, with clear skies, highs in the low to mid-70s, and cooler temperatures along the coast, thanks to a sea breeze.

Saturday will feel much like Friday, with highs in the low 70s. Temperatures will cool back to Boston’s normal high of 65 degrees Sunday as clouds increase and bring the chance of a sprinkle or two during the day.

The workweek kicks off a warming trend through the middle of next week, forecasters said. Monday also has a slight chance for showers with seasonal highs between 65 and 70 degrees. Look for highs in the 80s on Tuesday and Wednesday, forecasters said, accompanied by mild nights.
