The overall theme of the extended will be the changing temperatures. We begin under high pressure to the north, allowing for temperatures to gradually tick upward through mid week. We will range in the upper 60s to low 70s today, with highs finding the upper 70s to around 80 on Thursday. A cold front then passes, ushering in cooler Canadian air this weekend. Looking below, these could be the coolest temperatures we have seen since the late Spring. Most locations will range 10-20+ degrees below average Saturday & Sunday mornings (as seen below).
Looking at Saturday night lows from the NWS, mid to upper 30s can be expected across the higher terrain, while low 40s here in the valley. Even cooler temperatures will be possible, depending how quick cloud cover clears out and high pressure sets up across the area. Things will likely be closer to the low 30s in the high terrain and upper 30s across the valley, but time will tell. Either way, this leaves a concern for frost and near freezing temperatures. Those who have sensitive plants, start planning for these conditions now.
Along with the cold front Friday, increased cloud cover will be across the area, where locations in the far north could see a few sprinkles/light showers. The expectation elsewhere will mainly be a mix of clouds and sunshine with highs in the low 70s. Chilly fall temperatures then arrives thereafter.
