Lower dewpoints remain on Tuesday…

Today’s weather will be nearly identical to yesterday’s, again with pleasant temperatures and low humidity. The difference is we won’t have a breezy day like we saw Monday. Mostly clear skies follow overnight, and not quite as cool as it was Monday night.

Temperatures notably increase mid-late week as wind direction shifts to the SW and invites a warmer flow in ahead of the next cold front. This front is due to arrive Thursday night with perhaps an isolated or stray shower possible, then cooler once again to end the week and begin the weekend. The back half of the weekend could feature scattered showers and thunderstorms later in the day, and showers may continue into Monday.
