December 7: Cold Weather Ahead, Daily Links

WEATHER

The stubborn clouds of the past several days have finally broken up, allowing some weak December sun to shine through.  Despite the mix of clouds and sun overhead, temperatures will remain cool all day, only reaching the mid to upper 40s for highs:
wednesday-highs

Those temperatures will drop to near freezing tonight, with a very slight chance of a sprinkle or flurry as the next system makes its way through.  Futurecast is decidedly unimpressed with our precipitation chances overnight:

Cold weather settles in for the rest of the week…highs Thursday will top out around 40°:
thursday-highs
It will feel substantially colder than that, though — northerly winds at 10-15 mph will keep the wind chill around freezing all day!
thursday-wind-chill

We’ll start off near 20° for lows both Friday and Saturday mornings.  When temperatures drop to that level for the first time in a while, it’s time to think about the 4 P’s: plants, pipes, pets, and people.
Plants: Odds are you’ve already brought them in or given up on the garden for the winter, so I’m not too worried about this one.
Pipes: Make sure your outdoor faucets are winterized, but you don’t need to worry about your indoor plumbing at this point.
Pets: Don’t let the cold air catch your furry friends without preparation!  Outdoor animals need a shelter and some blankets to snuggle up in.  Or you can make them indoor animals for a couple of nights.
People: Check your furnace, if you haven’t already, and make sure your chimney is clear if you’re going to use the fireplace for additional heat.

The next chance of rain heads our way Sunday…there could be some sleet mixed in IF the rain starts in the morning, but for the most part we’re just looking at cold rain showers:

Another significant shot of Arctic air could head our way by the latter half of next week — that’s a LONG way off in forecasting terms, but the long-range forecast models have been consistently pointing toward that trend:

However, those forecast models have been inconsistently depicting the specifics of how cold it will be, how long it will last, and whether or not we’ll see any wintry precipitation.  We’ll keep an eye on it…
