God bless the IEM data plotter. For the NC State climate reporting site
On a certain date, what is the chance a temperature below a certain
threshold would be observed again that spring season

Regarding ATL area, it seems that today's freeze wasn't the latest but was one of the latest on record. We dipped below freezing at 1 am and came above at just after 8, meaning we had 7 hours below plus the frost. Cherry trees were wilted looking until the sun hit them but it's also going to set the lawns back even more.
 
Just remember this is normal, plants will regrow, it's great walking weather, it feels like fall, and it's so much fun!
I’m glad you’re starting to understand ? beautiful morning for sure .. great for a nice warm cup of coffee with the heat on ... hopefully everyone protected what they could that could die in this type of weather round two tonight!
 
We just tied a record low
Yes isn’t that what we’ve been cheering about all morning? I’m talking about global warming you know making our averages warmer over time and now has made our climo snow less I think it was 4 inches last year but new climo has made it like 3.3 now .. something like that .. it hits hard in the winter time and probably is what’s causing these past few bad depressing winters around here

We just had a wall to wall below normal winter and almost no snow so "averages going up" doesn't exactly explain the lack of snow especially given we have had winters with AN temps and AN snow. Additionally 1/1/90-12/31/99 was the worst decade for snow we averaged something like 2 inches so this recent GW train that is causing less snow doesn't entirely fit that narrative. Broad brushing GW for our lack of snow is the easy way to explain it but there is likely something deeper that has favored SE ridging/PVs going into other continents/a general lack of a -NAO/and west coast troughing. Maybe the answer ties back to GW I'm not sure but you can see clear decadal or multidecadal flips in the 500mb height anomalies globally and right now we are in one that stinks.

Lol feels like we switched it every break in the North Atlantic has lead to a -NAO it seems
