Hi and a good Thursday to you all! Some of you are waking up to a winter wonderland out there as most of the northern counties received much snow from yesterday's cold front system. It all began on Wednesday afternoon and into the night hours. Some areas received more than 6" of snow and actually I have one of a my good friend in Starkville who measured 5" of snow in his yard. Around Jackson, we only received traces of snow. I expected more and we should have received more, but it switch from snow to rain for the most part. I saw this switch happened right before my eyes and I knew that it would be bad as far as accumulations go. I believed it switch back to snow during nightfall, but by then most of the rain was heading toward the east. Still, we were able to get traces of snow and it sure wasn't enough to cancel classes or work although roads will be slippery today. I am going to try to put some pictures of this winter storm up later today, so please be sure to drop back and view some of the pictures.
Right now, current temperatures are holding steady in the lower 20s in the Jackson area and across most of the northern and central half of Mississippi. Wind chill is in the teens. Although cloudy for right now, we should see sunny skies later today but I don't think it'll give us much in terms of warmth. After today, we are going to start a warming trend and we will end up being in the 60s by Sunday! Talk about your early spring!

What's Happening Atmospherically
We are still getting some very cold air advection(850mb) pouring in here which will be the main factor for our cold weather conditions today. The cold front that brought in precipitation and snow has moved off toward the east and behind it, cold air has maintain its stay along with high pressure. This high pressure will give us sunny and dry weather for the remainer of the week making for a rather quiet period compared to yesterday's snow. Oh by the way, did I mention we are going to have temperatures in the 60s late this week!

The reason for this period of warmer and drier conditions is due to a lack of blocking in the North Atlantic. By analyzing the Madden-Julian Oscillation, as meteorologists we have observed that the lack of blocking in the North Atlantic would lighten up and decrease a bit therefore allowing for typical La-Nina conditions. This season we are in a La-Nina pattern. During La-Nina conditions, typically you have warmer and drier conditions here in the Southern Region but of course this winter season has certainly strayed away from that. So, what this means for you and I is that for the next few days we will experience warmer and above normal temperatures. Maybe the groundhog prediction of an early spring will come true after all.lol For Saturday highs, we will be at our normal highs for this time of month. Then on Sunday, we will be above normal temperatures and the ECMWF(European model) shows this warm weather continuing throughout early next week as well. By Sunday, models forecast that we could be all the way into the upper 60s. So if you are tired of this cold and wet winter, get ready to celebrate because warmer conditions are ahead. Below is a picture of 6-10 day outlook of this month. The orange shaded area means region with above normal temperatures. The blue stands for below normal and the unshaded area stands for normal.
Today
I highly doubt if we get above the freezing mark today. We are still stuck in the lower 20s and it's past noon. Highs were supposed to get up into the mid 30s. I think we will fall short of the freezing mark and stay in the upper 20s or lower 30s today in the Jackson area. Along with strong winds blowing from the north at 10 to 15mph, it will make the air feel like it is in the teens. This is definitely the day to wear all of your winter gear and pull that sweater out of the closet that your grandma gave to you this Christmas. Clouds should begin to clear off by late this afternoon or evening. You will still need to be safe on the road as we will be below freezing for most the day.

Tonight
Again I would like to reiterate driving safely tonight as temperatures will be below freezing keeping roads iced over. With clear skies tonight, I believe temperatures could drop below twenty degrees for some areas. So, I am going to forecast for the Jackson region with temperatures down in the teens tonight. It is going to make for a very cold night. So please stay warm in your house and stay snuggle up under your blankets. Also, just a quick reminder. Don't forget to pray for those who don't have a warm home or blanket to sleep under. Those who are living out on the street in this cold weather. Continue to pray and thank God for your blessings. Winds should become calm by the end of the night.

Friday's outlook
Look for yet another cold day on Friday as temperatures will strive to rise into the upper 40s. Sunny skies should help to brighten up your day if this cold weather doesn't do it.

Stay warm and God bless!
