Moderate risk expanded into central Georgia. There were rumors going around on Twitter that the SPC was going to go high risk over portions of Mississippi and Alabama with the first Day 1 outlook. One person said the weather service in Birmingham talked them out of it while another said the area was drawn out, but a lead forecaster said no. All this supposedly in NWS chats.

Another "loaded gun" sounding out of LIX this morning. A little cap, steep lapse rates above a slower lowest level, enough shear for all modes of severe.
Jackson has more shear but less instability. So another potentially scary day up in South Mississippi. Y'all stay weather aware today.

I’m not a hydrologist and I realize a majority of Mississippi River water comes from up north in the spring. However, I’m on the levee every day and it continues to fluctuate back and forth close to flood stage. They predict a fall then N Mississippi, Louisiana, Arkansas, and Alabama get soaked again in this crazy stuck pattern. I have watched for weeks how these southern rain deluges contribute to constant fluctuations in the river forecasts and spillway openings. Now here we go again. I know the weather is being overshadowed by current world crisis but I think this pattern is unprecedented. What is this storm.....number 12 or so for the year? They just keep coming and it looks to continue.
