An overcast morning will transition into the nicest day of the week, as clouds break and temperatures could top 70 away from the coast, the National Weather Service said.

Just under 2 inches of rain fell across Cape Cod and the islands in a dreary and cold Tuesday, meteorologist Bill Simpson said. Despite near continuous drizzle in Boston through last night, Logan International Airport recorded only 0.13 inches of rain.

The heavy cloud cover at daybreak has already showed signs of thinning during the morning commute. By mid-morning, skies will be mostly sunny, Simpson said.

Today’s temperatures will be 20 to 30 degrees higher than Tuesday’s, forecasters noted in a discussion posed on the weather service website. Cities like Lawrence and Fitchburg will see highs reaching 70 degrees, forecasters said. Temperatures will likely reach the mid-60s in places along the coast, including Boston.

Showers could develop after midnight and linger into Thursday morning’s commute, Simpson said, though skies will again clear. On Thursday, temperatures are expected to stay a bit cooler than today, with inland highs reaching the mid-60s.

On Friday, temperatures will be seasonal, in the upper 50s, Simpson said. There’s a slight chance of showers in the morning, though skies will clear after 10 a.m., forecasters said.

This weekend will see sunny skies and temperatures in the 60s, Simpson said.
