Severe Weather Liveblog is a collective effort to keep Kossacks safe when a large severe weather outbreak takes place. These blogs will be posted as needed, based on user-interaction (comments) and evolution of the severe weather event.

If you have emergency information that needs to be added to the diary (reports of tornadoes on the ground, emergency information telephone numbers, etc.), please indicate so in the subject line of the comment to lessen the delay in posting it to the diary.

Right now, aside from myself, the editors of Severe Weather Liveblog are not4morewars, boatsie and Predictor. If you'd like to help, drop me a message.

Please keep in mind that any Severe Weather Liveblogs posted are not places for tasteless cracks at other people's expense. Post cheap political/social shots towards those affected at your own risk.

A rather strong line of thunderstorms is moving through Mississippi and Louisiana right now, and the SPC has issued a Severe Thunderstorm Watch as a result. The main threat with this line of storms will be strong winds (with wind gusts of 75+ MPH possible), although some large hail and maybe an isolated tornado can't be ruled out.

Here is the line as of 136PM CST:

Watches


Red = Tornado Watch ... Blue = Severe T'storm Watch ... Click image to go to SPC watch page.

Updates

UPDATE 1 (145PM CST)

Here's one of the storms moving into Jackson, MS right now:

The NWS warning associated with these two storms say that 70+ MPH winds are possible.

UPDATE 2 (206PM CST)

My apologies for messing up the time conversions. I'm back in Eastern Time at home for spring break, so I might screw up occasionally with the times.

There are two tornado warnings in effect for counties in Central Mississippi right now. Here's the radar, with the red polygons indicating the tornado warnings:

Here's the velocity image for the one near Jackson, MS. Red is wind moving toward the radar, green is wind moving away from the radar. That little hook you see in the image southwest of Brandon is where the radar indicates rotation in the thunderstorms, meaning that a tornado can form or already has formed.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
