Everything about this forecast has been wrong. This has been the wettest winter I have ever seen. My yard has been soupy all winter because it won't quit raining. But yet we were suppose to have a dry winter. LOL!!!!

wrong forecast

wet and cold instead of promising sun and warm. no one could give a good forecast anymore :(


This weather prediction has been everything but correct. The sun has barely shown its face the first week of February.

Snow Chances

We have a chance for snow in Georgia next week. If it happens, it will be our first snow of the year. If your living in Georgia, keep your fingers crossed for this one


it's 28 degrees F at 0530 in the AM

Sun...finally!!! Yes

So the sun finally came out here in Georgia. I think Beauregard Lee saw his shadow. So 6 more weeks of winter. Oh well.


I’ve got itty bitty pea plants that survived the (very mild) winter in Upstate SC. With >normal temps forecast for February, I’m going to peel back the plastic cover and cross my fingers. Fresh peas! What could be better?

SNOW AT 8:00

It was snowing at 8:00 today a little bit, now its raining a little.


3" of snow in Henderson, NC


Snow in Raleigh, NC!!
