Sniffing Out Arctic Air

I know it's been awhile since I last opined about the weather, but an Arctic intrusion is likely to rudely remind us all that the 3 coldest months of the year are just around the corner.  I simply wanted to give y'all a "heads-up" as to the situation as I haven't really heard too much scuttlebutt about such cold.  Remember, it's been quite warm the last several weeks as you know.  Here is the warmth depicted graphically:
Yes...it has been warm.  But all of that will change beginning this weekend.  It will be a step down process with a reinforcing shot of truly modified arctic air invading Sunday afternoon.  The polar air coming Friday and Saturday will be chilly but the real slap will be Monday!  Here is Saturday morning's temperature anomaly...
Note what lurks in the plains and Rockies...That will arrive Sunday afternoon but will really be felt Monday compared to averages!

However, another warm spell will give relief quickly from the cold come the few days following Thanksgiving...However, look what is back in the Dakotas and high plains drifting our way!
Although the cold will not affect us here in the east as much as the impact will be felt further west, compared to what we've experienced to this point in November, this will feel COLD!  The graphic below is from the Euro, a 7 day average for the 1st 7 days of December.  That is a very cold continental US 7 day map!  Keep in mind, this is in °C!
So...the bearer of bad news?  Well, not so much as I believe December for us here in PA will end up a degree or so either side of normal...but again considering how warm both October and November have been, it will feel quite cold to us.  I will also leave you with another type of "Cold Shot" many of you might enjoy...I know I do!

Stevie Ray Vaughn...enjoy!

And enjoy your upcoming Thanksgiving week and remember to give thanks in some small way for all of which with we are blessed...

AA:  A step down to colder weather the next couple of weeks.  Sunday-Monday will be quite chilly.  Then a moderation before some serious chill will invade the 1st week of December.  Walks will be brisk in the lot; but they will be!
