Temperatures are set to top 70 degrees today, kicking off a warm and dry week, the National Weather Service said.

Clouds moving into the region late this morning will largely dissipate by the afternoon, leaving mostly sunny skies. A high pressure system just offshore will help temperatures climb above 70 degrees inland, meteorologist Charlie Foley said. A light wind coming off the water will keep areas along the coast slightly cooler, forecasters said. Boston is expected to reach 69 degrees.

Tuesday will be a near carbon copy of today, with more sunny skies, no precipitation, and temperatures along the coast in the upper 60s and low 70s inland. Those conditions will continue through the week and into the weekend, Foley said.

“This is going to be a fairly prolonged dry spell,” Foley said.

The high pressure system parked over the region combined with already dry conditions does increase the odds for brush fires. Since March 1, Boston Logan Airport has had 3.14 inches of rain less than normal, Foley said. It doesn’t appear April showers will kick in for the last days of the month, either.

“March started off dry and April will be even dryer,” Foley said.

Though some wind is possible Wednesday, Foley said, a lack of gusty winds will help keep fire risks down, despite such dry conditions.

“We’re not looking for any strong winds, which is a good thing,” he said. “Until we get into full green, which generally occurs around mid- to late May, folks should be careful in the woods.”
