An upper-level low hasn’t quite given up yet. It will return on Monday, bringing more changeable weather once again. Clouds will be frequent, with the sun making only occasional, brief appearances. There will also be a slight chance of showers as the day progresses. By Tuesday, however, the high-pressure system will have fully taken hold again, bringing bright sunshine under an increasingly cloudless sky. We’ll start Wednesday just as nicely, and it will stay that way until around noon. But a strengthening wind already signals a significant cold front, which will reach us from the west starting in the late afternoon and pass over us during the night into Thursday. Behind the front, we’ll remain in a cold, damp northwesterly flow until the weekend, with further snow showers extending down into the low-lying valleys.
