It’s that time of year again. The time of year when the “wedge” of colder air stuck against the mountains to the west can keep us cooler than expected. Highs during the day today didn’t get too far past 60, which is the coolest since early May. (Note: Actual highs were in the mid-60s near midnight.) While we’re stuck in the wedge through the evening, a cold front helps clean out the atmosphere tonight.

Through Tonight: Fog and drizzle continue to be an issue this evening and into the night, and a brief shower is possible. A cold front passing late tonight should eventually start to get the atmosphere mixed up. By morning, skies are clearing, and winds are out of the northwest. Lows range across the 50s.

Tomorrow (Tuesday): It’s often hard to kick out the cooler air stuck against the mountains, but gusty northwest winds should help. After some morning cloudiness, we trend partly sunny with time, and highs are near 70. Winds are around 10 mph with gusts past 20 mph.
