Mississippi Valley Severe Storm Update

By -
Here is my forecast for now through midnight.
Readers in east central and southeast Iowa should really keep an eye on the weather the next few hours. Giant hail (≥4") likely if supercell thunderstorms develop. So, I would urge you to put your car in the garage along with anything else that can be damaged by hail. I also believe it is quite possible for a tornado or two if supercell thunderstorms develop.

If you have friends/relatives in the purple area, please make sure they are aware of the threat.

Here is the radar at 3:37pm.

2am While the risk of tornadoes may continue during the night, this will have to end my coverage.  Note the risk of tornadoes farther east later today.  1:35am Wednesday: Tornado watch will likely be issued for the outlined area, including the Kansas City Metro. Make sure you have a way to receive tornado warnings the rest of the night.  11:55p Tuesday: New tornado watch has just been issued for most south central (including Wichita), southeast and east central Kansas.  This watch is in effect until 7am Wednesday.

--- This Forecast Has Been Updated  --- You Will Find the New Forecast Here After a quick look at the new data this evening, I believe the forecast is still good. There may be light amounts of freezing rain in north central Texas as far south as Waco. It will not be enough to cause power outages but -- if it occurs -- it will make roads very slick.  The snow amount forecasts haven't changed. I believe DFW will receive 1-3" with heavier amounts as you go northeast. I-30 will become a mess for its entire route.  --- original forecast still valid --- Here are the latest NWS winter weather warnings and watches as of 3:15pm Note: the white "hole" in southwest Texas will be filled in with a purple winter weather advisory for 1-3 inches of snow.  Color codes: Pink = winter storm warning  Dark green = winter storm watch Purple = winter weather advisory  Bright green = ongoing flood warning  Dark blue and bright turquoise = freeze warnings.  As expected, t...
