Change is definitely in the air for the second half of the weekend.  After staying well past its welcome, this unsettled and moist air mass is on its way out, replaced by a cooler and drier one that sticks around for a few days.  Expect refreshingly cool 60s, plenty of sun and a pesky breeze (good for kites, right?) today and tomorrow. We’ll lose the wind by Tuesday, but may have to wait until Wednesday for temperatures to warm back into the 70s.

Today (Sunday): Any cloudiness that lingers for early-risers quickly breaks up as drier air works in behind last night’s cold front. Two things you’ll note as you step outside, besides skies becoming partly to mostly sunny, are the drier air and the wind.  A stiff breeze from the northwest, gusting near 30 mph, ushers in that fresh feeling with highs reaching the mid-to-upper 60s. Confidence: High

Tonight: Mostly clear skies and diminishing winds invite a bit of a chill.  Temperatures fall quickly in the dry air, and we’ll see them drop all the way to the upper 30s to mid-40s (suburbs to city).  We should keep just enough of a breeze to prevent temperatures from dropping even further. Confidence: High

Tomorrow (Monday): We really get into the cool air tomorrow, and while it’s still plenty bright, temperatures aren’t able to respond much.  Highs only reach the low-to-mid 60s under partly to mostly sunny skies. The wind doesn’t do us any favors either, remaining a bit gusty out of the northwest. Confidence: High

Tomorrow night: Another cool and dry overnight, perhaps even qualifying as “cold.” Skies remain mostly clear, and with the wind dying down we could see a few areas of frost in outlying areas. Lows dip to the mid-30s in the coolest suburbs, to the low 40s downtown. Confidence: Medium-High

A LOOK AHEAD

Tuesday is still on the cool side, but we do see the beginnings of our return to more seasonable temperatures.  Winds are light, and with mostly sunny skies highs should reach the mid-to-upper 60s. It’s not as cool Tuesday night, either. Expect partly to mostly cloudy skies with lows in the 40s. Confidence: Medium-High

We start the day Wednesday with our next system far enough to the northwest to allow us partly to mostly sunny skies and highs rising into the 70s. By afternoon or evening, however, it could be close enough for increasing clouds and maybe a shower to the west. Confidence: Medium
