It was a hard blow this morning to our town hearing that the missing little boy’s father confessed to killing him.  Our town people have been searching night and day in very cold weather.  I just do not understand it! 😡

That is horrible to hear. I hope for the rest of his life it's 33f and raining.

Temp and dewpoint both stuck at 41 currently with a very heavy drizzle falling along with some  dense fog.  If it was still St. Patty's Day, I would think I drank too much and woke up in Ireland.

(Except for the fact they are actually several degrees warmer right now).

Interesting (discussion from OHX):

Quote
Area Forecast Discussion
National Weather Service Nashville TN
336 PM CDT Sat Apr 7 2018

.DISCUSSION...

This was not just an atypical day...it was record setting. Well,
almost. Afternoon temps have been stuck in the 30s (!!) which
would be enough to smash the record low max temps for the
day. However, temps were in the 40s (above these "cold records")
just after midnight, thus no records were set during daylight
hours today. Nonetheless, temps in the 30s with wind chills under
30 at mid afternoon on an April 7th is remarkable. And the
occasional reports of flurries across the south and east counties
at mid afternoon were special, too.

Temp never left the mid 30’s here. Clouds finally breaking for a clear sky and calm wind- not so nice for blooming plants.

As bad as this cold snap is, it can't hold a candle (or icicle) to April 2007.  I looked back on some weather records from an old weather station I had back then, and on 4/7/2007 (yep, that's today!) we dropped to a low of 26.  I did not get above freezing until noon the following day, and only achieved a high of 40 around 5 p.m. in the afternoon.  That night we dropped to a low of 23!  No wonder every tree was fried to crisp, and many trees died outright.  The length of time below 32 literally froze the sap in the trunks of many trees, doing irreparable damage. 

One night around 28 doesn't seem too bad now.

That might do some damage to all things green and growing.  Hopefully, you won't be that cold for a long time.  Length of time below freezing plays a big part in how much damage is done.

We are no where near our forecasted high if 45. Currently at 37. My Japanese Maples are almost sure to be toast. Though, one of the has fully leafed out and should be good to go. The others will be crippled, at 20ft tall, there is no way to prevent the damage.

Most trees are ok above 28F.  Below 28, damage begins.  If you stay there for hours, the damage becomes extensive to any foliage or flowers that have opened.  If you drop below 25 and stay there for several hours, some twigs and branches are damaged due to the sap freezing in the cambium (the living tissue that transports water and nutrients in plants).  The longer you stay deep into the 20's, the more damage occurs to plants primed for spring growth. 

Currently, we are cloudy with some drizzle falling here with a temp of 37F.  The longer the clouds linger, the less the temperature drops.  Other than that hope, we are screwed.  ::candle::

I had 21 degrees for a low on the second night of the 2007 freeze. I remember walking outside early that morning and smelling the burst cellulose. It smelled very strongly of fresh cut lumber and grass. Our hickory tree lost all of its foliage and didn’t get it back all year. Not expecting anything like that tonight.

March 2007 had been so freakishly warm that the trees were mostly leafed out by this date in April. So, it was a one-two punch worst case scenario for the trees. At least the foliage is well behind where it was at that point.

I will have to agree with Bruce this time. Models are leaning toward a widespread severe threat or two or three over the next couple weeks. Question is does it make it to the Mid South or Southeast.Might be a lot of model watching going on.

Woke up to 31F this morning, and not the 26 forecast by the NWS. Models missed the mark with yesterday's highs, but got it right last night.  By late yesterday afternoon, most short term models like the HRRR and RAP were showing lows closer to freezing in East TN, rather than the mid 20's.  Clouds didn't clear out here until around 4am, which probably helped.

KY didn't fare so well.  Morning temperatures there had dropped into the low and mid 20's, and even to 19 at Monticello in Wayne County.  Same for the plateau in TN.  Most reporting stations in mid and west TN were between 26 and 32.

All the foliage on my oak and hickory trees turned black and died that spring, and the trees had to set new buds and start over.  I remember by early to mid May, some trees were just leafing out again, making for a bare and ugly spring.  Several hickory trees in my neighborhood died that summer due to the freeze and the drought that followed.  Of all my years in TN, that was the worst for anyone with a green thumb.

It has been below freezing out here since about 10:00 PM last night.  We hovered around 27F for hours.  High clouds encroaching from the SW helped keep us from disaster ... but there will still be  foliage damage.
Hire the left-handed --- its fun to watch them write.
