The potent mix of severe weather ingredients continues after darkness, putting several Midwestern and Plains states on high alert.

Earlier, for only the second time in U.S. history, the Storm Prediction Center issued a high-risk warning more than 24 hours in advance, said Russ Schneider, director of the center, which is part of the National Weather Service. The first time was in April 2006, when nearly 100 tornadoes tore across the southeastern U.S., killing a dozen people and damaging more than 1,000 homes.


Forecasters say life-threatening tornadoes are likely beginning this afternoon. Storms will also bring large hail and damaging winds.

Big weather day in store for the Nation’s mid-section where the SPC has outlined a high risk for severe weather across the area including the eastern half of Nebraska, eastern half of Kansas, and a chunk of northern Oklahoma. Of course, the high risk areas are surrounded by a moderate risk area as well. CAPE values expected to reach into the range of 2500 to 4000, so tremendous instability. Helicity values also climbing into the 300 to 600 range, so the recipe for severe weather seems to be coming together

Looks like our best chances for rain will come late in the day on Monday and into Tuesday. While there is some risk of severe weather for Monday and early Tuesday, SPC did not outline a specific area for a slight risk. Main threat should be in the form of damaging wind with embedded severe thunderstorms. Rainfall amounts late Monday and into Tuesday could be respectable with 1 to 2 inch amounts possible with the stronger storms.

The upper trough moves by Tuesday taking the rain east of us and returning us to a dry pattern on Wednesday. James Spann

  1. Watch my RT’s throughout the day, as I do it within seconds/ minutes as they come in. I also monitor maps:

  2. Severe weather carries on = Be Alert TX, OK, KS, NE, SD, IA, MO, MN

    Areas to watch currently 1245pm CDT 4/14/2012: North Texas, West/Central Oklahoma, South east / Central Kansas , northward through central Nebraska into south dakota… Also watch Missouri, Iowa, Minnesota.

    These storms will be intersecting the above named areas in the near term *day or less from now*…. have severe weather plans ready just in case…. damaging winds, large hail, and possible tornadoes are associated with this storm system.

  3. UPDATE — Have your severe plans ready — TX, OK, KS, NE, IA, MN, SD, WI

  4. Be on the ALERT — Minnesota and Wisconsin

    The track of the current storms in Nebraska, Kansas is heading east northeast — this means South Dakota, Minnesota, and Wisconsin — time to prepare for imminent severe weather is NOW — there are possible tornadoes, also for SURE damaging winds and hail.

    Make sure to secure loose outdoor items, protect the car (if you have one) and make any last minute preparations in case the severe weather turns violent in these areas.

  5. Chicago north to Milwaukee west to Madison Wisconsin = BE ALERT NOW

    watch chicago webcams to see the storm roll in : and get the word out to anyone up in the area — chicago north to Milwaukee — also north Central Michigan.

    If you live north of Chicago all the way to Milwaukee Wisconsin — west to Madison Wisconsin… prepare now.. damaging winds, large hail, and possible tornadoes are heading your way.

    Also be prepared in central Wisconsin.. north towards the border of Michigan and Canada…

    Further west.. Minnesota later tonight..
