On this date in 2000 deadly tornadoes ripped through the deep South. Tuscaloosa, Alabama killed twelve. High winds & severe thunderstorms roared up and down the East coast. Often with severe weather in colder months record warmth moves unusually far north and back in 2000 on this date Boston set a record high of sixty degrees ahead of the cold front. The Metro Area was under a tornado watch in the morning and behind the front we had snow showers in the evening as temperatures plummeted. National hit sixty for a high, but not a record and recorded a low of twenty nine degrees. A winter storm watch was posted for our area the next day at noon for that night. We saw a pattern shift after that warm December day. Just two days later we had one to three inches of snow. Highs held in the twenties and thirties for the rest of the month except on Christmas Eve day when we only hit forty degrees.
We have had a very mild December so far. The high temperature has been averaging eight degrees above the climatic average high. There are signs of a pattern shift after this Thursday's cold front. The models have been hinting at this shift for some time now but have not settled on just how dramatic of a change it will be. Suffice to say, if you are a snow lover after Thursday we will at least be in the ball park of receiving winter precipitation if some sort if a storm were to develop and track south and east of us. Even after the 'pattern change' it looks like we could warm up again and have rain between Christmas and New Year's as a storm tracks west of the mountains but stay tuned that's a long way off.
