First Fall cold front arrives today

A seasonably strong Fall cold front arrives in central Virginia today. As of this update, the front is already moving through the Valley of western Virginia, with dense fog and light rain, as well as cooler temperatures moving in behind the front. Here is the surface observation picture as the cold front is just moving into the Valley:

Temperatures to our northwest are already in the 40s and 50s this morning behind the front, and that's where we'll be Friday morning!

As for today, though, the rest of us in Virginia will see the increasing cloud-cover from the west through the first half of the day, with the front clearing the state to the southeast by sunset. Expect scattered showers and thunderstorms along and behind the front this afternoon and evening in most of central Virginia, with overcast skies and cooler temperatures. High temperatures Friday and Saturday will remain cooler-than-normal for mid-September in the 60s (average highs for those dates: 81 degrees). As for morning low temperatures, we'll be noticeably cooler in the 40s and low 50s, so it's safe to turn off the A/C and open the windows! A word of caution, though...mold spores are an issue right now after recent heavy rainfall, and if you have an allergic reaction to mold, you don't want to open all the windows and let the mold spores indoors. In addition, it's ragweed season, and if you're allergic to that, keep the windows closed! If you do open windows through the weekend with cooler temperatures, then you WILL need to keep running that A/C to filter your in-house air and remove the invading allergens.

Nevertheless! Enjoy the first taste of Fall through this weekend!
