Well, that wasn't much fun.
At 11:55, the temperature had warmed to 9°C before cratering. Six hours later it was 1°C with wind gusting over 55 kph and snow flurries. The forecast was bleak, so I went out and gathered remaining tomatoes and peppers (need to find recipe for fried green tomatoes!). Not fun at all!
Forecast is predicting a overnight low of -2°C and one to three inches of wet, wind-driven snow (gusts to 50 kph) by midday. As the National Weather Service's Area Forecast Discussion from this afternoon wrote:
Coming right on the heels of yet another mild stretch in our exceptionally warm fall to date, this short stretch of wintry conditions will feel more harsh than it typically would by this late into November.
IOW, seasonal weather is going to feel a lot colder because there hasn't been any transition, just an abrupt change. Oh well!
