After experiencing warm temperatures most of this week, a cold frontal passage last night ushered in more fall-like weather. A high-pressure system will settle in to the region, bringing with it a much colder and drier air mass. While temperatures Monday through Thursday were 10°F above normal mid-60°Fs, temperatures this weekend could be as much as 10°F below normal. With clear skies and low wind speeds, the conditions tonight will be ideal for radiative cooling, allowing temperatures to drop into the mid 40°Fs.
The rest of the weekend should continue to have mostly sunny skies, with the possibility of a few high clouds on Saturday. Temperatures will warm back up to more seasonable values in the early part of next week, with the next chance for precipitation coming Wednesday or Thursday.
