Interesting and helpful. I think this week we may be posting some interesting lows. I need to go outside and toss more mulch on some of my tender perennials, or I guess I should just plan on growing some new ones this coming season.

Suggle up; stay indoors; stay warm!

I agree ncrescue and I wonder, given the wildchild polar jet stream that has been entirely weird for 2 years now, if we are headed (or arrived already) for a less temperate climate with much greater extremes. Not just here in the Carolinas.
To me, the last two years weather extremes have felt distinctly Southern New England but precip. channeled by the wayward jet stream has increased as it draws moisture up from the GOM.
So what I'm planting, planning to plant is going in not as deeply as I might have installed it 20 years ago.
It might require some winter protection to the plant/shrub base but that's to be anticipated.
While I'd love to have some type of greenhouse, what I have is a 2 car oversize garage facing south east and it
serves better than a glasshouse for more insulation from these wild swings in temperatures.

I honestly don't think we can rely on historical data much anymore as it relates to temperatures/rainfall and extremes
because the extremes are becoming more frequent.

I'll add that planning for extremes is next to impossible.

Didn't get that extra mulch down before the rains started, so I imagine I will be planting seeds of those tender perennials this spring!

I get so bored when I have to stay indoors. I even started working on my income tax! Gotta be bored to do that!

I see 9F this morning. Been there for several hours now. I'm more concerned about water lines bursting than plants surviving. I can't be there to unwrap them anyway, so they're on their own.

It was 4 degrees here in Fountain Inn, SC this morning at 5AM when I got called in to work and probably colder by sunrise.

I've been busting and freezing my butt at work all morning due to this extreme cold. I work for a waste water company.

My water was fine this morning, I just hope it stays that way, it's a balmy 18 degrees now, in the sun.

Well, lunch break is almost over, got to get back at it!

We ended up at 5F here.
I kept my plants wrapped as we did not get above freezing and it is predicted to be 14F tonight.

Attached is the summary graph of the recent cold event at three different weather stations in the area: Raleigh-Durham Airport (KRDU), Lake Wheeler Rd Field Lab (LAKE), and North Durham Water Reclamation Facility (DURH).

Overall, there were 40 hours below freezing and 29 hours below 20F at KRDU.

Well, that data matches what my small cheap thermometer said. I live down the street from the Lake Wheeler Road Field Lab and I wondered if my equipment was accurate since everyone else was talking about it being colder than 10 degrees. I heat the greenhouse with an old wood burning stove so I had to go out and throw wood on the fire every hour and a half, so each time I checked the temps on the way. A roaring fire kept the greenhouse above 45 - so it was all worth it.

And today I may lose plants due to flooding. Hope those Cardinal flowers at the lake have good roots!

Its been a crazy stretch of weather here with the cold and then that nasty storm the other day.

As far as the cold is concerned, it was so fascinating to get rain one day and the next day be so cold that the ground is frozen solid under your feet.
