A northerly breeze and highs in the mid-60s will ensure a fall-like feel to the day, said Meteorologist Rich Wirdzek.
Morning sun will give way to some clouds in the afternoon, and temperatures will fall though the 50s this evening.
Tonight, clearing skies and a lighter breeze will lead to "an exceptional cooling process," he said.
"It will by far be the coolest night we've had since Spring with lows dipping into the low 40s, with some upper 30s in outlying and low lying areas," Wirdzek said.
Saturday will start off chilly, but temperatures will recover nicely for the afternoon with wall-to-wall sunshine. Highs will be close to 70.
Sunday will be mostly sunny and a little warmer, with highs in the mid-70s.
