Big 24 Hour Change

Ok take yesterday and today, now bottle up both days and set it on the shelf because we won't be seeing the weekends weather for a few days. The next 24 hours is a major transition day for us in the weather world. Expect winds to slowly shift more to the SE as a High pressure system shifts east of our region. Winds alone can be a big story line because with a shift in the wind we will also begin to see a pull of more moisture from the Western side of the Gulf of Mexico. Dewpoint temps are in the 20s now but I'll expect Dewpoint temps to be in the lower 50s by Tuesday morning. As I wrote about yesterday, because of the major influx of moisture, instability, and shear (upper level change of winds), the Storm Prediction Center has issued a slight risk for the Lower Mississippi River Valley (which includes the Pine Belt). Day 3 refers to Tuesday with Sunday being Day 1. I have also noticed the models have slowed down the frontal movement, but the back end of the front has exited quicker. In other words, I'll be looking for our main rain event coming into play Tuesday PM and into Wednesday AM, but our precip should clear out by Wednesday PM. Tuesday's impact looks like a squall line event, which we could see pass through between 6pm Tues and 6am Wed., and my main concern is wind and heavy rain (flash flooding). Of course with other variables factored in the slight chance of a tornado is in my thoughts. As this is the first severe weather threat for the season, I hope you will stay up-to-date with this blog and our live weathercast . Thank you for reading!
