Temperatures this afternoon have touched 80 at Key Field and I expect a couple more locations to hit 80 today as the warm and humid air is continuing to surge in our direction today and through the middle of the week. We will be keeping highs in the 80s until Thursday.
Thursday is when the weather will become very active as a strong upper level low will be passing over us. As of now, models have slowed the timing down and have come into good agreement that the squall line with the cold front will arrive after midnight for all of us. There could still develop supercells ahead of the main line, but it appears this will be a mostly squall line event. However, even with that said, we may develop breaks in the line to allow storms to rotate and develop tornadoes, so all modes of severe weather are still likely from about 10pm Wednesday until 6pm Thursday. Along with severe weather will be the possibility of heavy rainfall and flooding.
Our system Thursday is one to pay attention to, as the Storm Prediction Center already has all of East Mississippi along and west of Highway 15 under their slight risk category for severe weather, and this will most likely be expanded and even upgraded to a moderate risk, so make sure you are prepared for severe weather. Remember that straight line winds can cause as much damage as a tornado. You will want to make sure your NOAA Weather Radio is working properly, and of course stay with us as Jeff and I keep you updated leading into and through the storm.
This system will exit late Thursday and we will clear out and cool down a bit for Friday before we warm back up towards 80 to start next week.
