PM Update: Glorious weather stays mild into Thursday ahead of gusty shower threat

Today featured near-perfect fall weather, and mild conditions aren’t in a hurry to leave. Our high temperatures this afternoon in the mid-60s to near 70 could even move upward a bit tomorrow before a front moves into the region. The front, being driven by a powerful storm heading east across the country, promises to bring a gusty shower threat that probably holds off till tomorrow evening or night.

Through Tonight: Good evening for a bike ride or long walk to wind down from work? With temps slowly falling into the 50s after dark, I think so. Partly cloudy skies and temperatures slowly dropping to lows in the mid-40s to near 50 rule the night.

Tomorrow (Thursday): Clouds increase during the day, but we should end up with a fair amount of sunshine overall. Highs top out in the rather lovely upper 60s to low 70s. As we get into afternoon and evening, a line of showers and embedded t’showers will be approaching quickly from the west. Right now, it appears this threat concentrates after 6-8 p.m. through midnight or so, but these things tend to speed up more often than slow down. While it’s getting late in the year for severe weather, the system’s dynamics may overcome many other negatives to produce at least an isolated wind damage threat with stronger activity.

Tropics: Hurricane Rafael is racing away into the north Atlantic, and is expected to become a powerful extratropical storm shortly. Satellite imagery of the system is quite impressive this afternoon, as the transition occurs.

Pollen update: All pollen types, including mold spores, are currently low.
