Currently
Happy Thursday to you all and I hope all is going well for you. Today is starting off for as being mostly cloudy and quite WARM. It actually feels like an early spring day outside minus the ample amount of sunshine. Temperatures are already in the mid 60s and like yesterday's forecast discussion, I do look forward to seeing temperatures reach the near 70s today. We are still maintaining breezy conditions with winds from the southwest at 10 to 15mph and even gusting at times at 20mph. Although it is quite warm this morning, as we go throughout the day we will see temperatures drop rather rapidly, as well as a chance to receive some afternoon showers.

What's Happening Atmospherically
We are certainly having roller coaster temperatures of late as temperatures are warm one day and cold the next. By yesterday, highs came about to 65 degrees and today will be even warmer. We had a strong warm front that push through yesterday and has now push toward northeast. It really brought out the above normal temperatures but as of today we will have a cold front dragging right behind it. By 1:00p.m. today, surface maps forecasts that the main low pressure system will be in eastern TN and southern Kentucky region, but also connected to it will be another low pressure that is going to be located in LA. How this low pressure systems affects us is by: 1. unseasonably-like temperature currently and throughout the morning, 2. scattered showers in the afternoon, 3. and will issued back in cooler weather. Although both the NAM/GFS models are not exactly clear on when the rain will be out, they do agree that there will be scattered afternoon showers. These will linger throughout the day and into the night hours. We are not expecting too much regarding the amount of precipitation, but we could see anywhere from 0.01 to 0.05 inch. Scattered showers will continue to linger through early Friday morning. Both the Canadian/NAM model show a rain-free weekend but the GFS does show possible return-flow out from the Gulf which could give us another round of showers Friday night.
The other main story of today is declining temperatures. Temperatures will decline throughout the day as MOS forecasts 50s by 7:00 tonight and mid 40s around midnight. Cold air will once filter back in into our forecast and by tomorrow we will have highs back around normal. The cold air will really be evident in north MS as it will be a 10-15 degree difference in temperature compared to the temp here.

Today
Scattered afternoon showers later as temperatures will reach in to the upper 60s and possibly into the 70s depending on if there are any breaks in the clouds to allow sunshine. Have your umbrella in hand and raincoat as both showers and clouds linger into our Thursday night. Winds will be from the southwest at 10 to 15mph.

Tonight
Rain will still be scattered through the area along with colder and windy conditions. A shift in wind direction will occur as winds will change from the southwest to the northwest as cold air filters back into our weather. Lows in the 40s.

Friday's outlook
Lingering shower in the early portion of the morning but clearing off leaving temperatures to be around normal this time of year. Be sure to join me tomorrow for your Face of the Sky forecast. God Bless!
