PM Update: Warm streak ends, cooler, drier air streaming in

Today concludes a stunning 10-day stretch of above average temperatures, all topping 60 degrees at Reagan National Airport. Since this morning’s high in the mid-60s, temperatures have tumbled some 15 degrees. Cool air continues to filter in overnight as skies partially clear. Seasonably cool conditions complement November’s final day, Wednesday.

Through Tonight: Partial clearing should promote a colorful sunset (post your pics to Twitter or Facebook). But if you haven’t been out since this morning, add a layer, as temperatures gradually dip through the 40s. It will be breezy as well, with winds from the southwest at 10 to 15 mph. Later at night, winds diminish a bit, with lows from the low-to-mid 30s in the cooler suburbs to the upper 30s downtown.

Wednesday: While not nearly as mild as the past 10 days, it’s still not a bad day. Skies are partly to mostly sunny, and temperatures manage to reach the low 50s. A breezing from the north around 10 mph adds a slight chill. As we’ve been used to 60s, you might consider an extra layer or heavier coat for this new weather regime, set to settle in for a while.
