We don’t remember having several nights of sub-freezing weather last winter, at least not six consecutive days in a row. Fortunately, we took precautions for possible freezing weather starting as early as November, draining the spa, and flushing the motor home plumbing. No sense in waiting until the last minute. We got this image of the birdbath next to the RV drive yesterday morning (about 10:30 AM) still frozen solid - one big ice cube.
The forecast is for warmer conditions returning by mid-week or so. Not so much sub-freezing nights and warmer days (up to the 60s or so). Click on the image to enlarge.
