Perfect Fall Weather

Soil moisture played a big role overnight in keeping temperatures in the lower 50s as opposed to the upper 40s. Still, it's a crisp morning, and you may even need a light jacket if you're headed to work or an early class. Today will be the coolest day of the week as an upper air trough continues to deepen to our east. Weak cold air advection aloft will continue throughout the day, which should prevent deep mixing from taking place. As a result, highs will top out near 74 despite full sunshine. Winds will be slightly weaker than yesterday but still gusting near 15 mph at times this afternoon. Another good radiational setup will be in the cards with light winds, clear skies, and very dry air. I don't say it's ideal because of the residual soil moisture. This will likely keep lows in the upper 40s instead of the mid 40s. Look for the low tomorrow morning to be a chilly 48.
