Over the next 24 to 36 hours our weather will be showery at times. We may even at times see an isolated thunderstorm in the mix. Overall, tranquil in comparison to the active time we will see on Christmas Day and into the overnight. This variety of weather will be due to a very strong low pressure system that will move through our area. Here are the players in our weather stage. 1. The low pressure itself will move from around the Greenville area around 6pm to the Nashville area by the wee hours of the 26th. 2. To the east of the low pressure will be the warm front. 3. To the south of the low pressure we will see the cold front. 4. The warm sector to the SE of the low pressure. 5. The cold air NW of the low pressure . . . . . and now here is how the weather show.
Ok, our first subject "Low Pressure" this is the main churn that keeps the air mass moving right along the aforementioned track. This is the engine to mix the air masses that are in place.
Subject 2, "Warm Front" . . . . . this front will usher into the area some very unstable tropical air. Along the front as it moves northward through the day we will see the potential of strong to severe storm development. Some of these could produce severe weather mainly in the form of strong and gusty winds, along with a few isolated tornadoes.
Subject 3, "Cold Front" . . . . . along this cold front and/or slightly ahead of it we could see the development of a line of storms known as a "squall line". Along this squall line we could see some strong to severe storms. Main culprits being hail and some strong and gusty winds. There could also be a few isolated tornadoes along this line.
Subject 4, "warm sector" . . . . . This is where it could get very interesting. This is the best area for development of "Supercells". These supercells could most likely produce tornadoes. These supercells may even at times be capable of producing a strong tornado.
Subject 5, "Cold air" . . . . . The cold air NW of the low will mix with some moisture and most likely will produce some mixed precipitation from the Memphis area and northwestward later in the evening and into Wednesday morning. There could be some significant snowfall amounts for West Tennessee and Northern sections of Arkansas. As for this area when it reaches most of our viewing area on Wednesday. The moisture will be lacking, however we could still see some snow showers. Temperatures will be in the 30s for the most part. Accumulation looks to be minimal.
