I have watch the weather very close since I was 16 years old in the piedmont region where I was born, and for the last 20 years on the Georgia coast. keeping up daily with the almnacs and daily city papers; I put into use our "nature signs as taught to me by my parents and grand parents who had a strong influence on me. I have never seen a weather predicting site any better than from Andrew. I have shown others printed facts to show its not get guess work. I was luckly to have found you last year. I have always made my winter prediction in by about the same time last year. we both predicted the same winter. have not made mine as of yet. 2nd week in july is my date. I and my friends and family are a big watcher of your reports.
for now I am feeling cold again for wivter.
thanks and keep up the great work.
