While Tornadoes, Rightly, Were the Primary the Primary Story Today,  Floods Will Be the Story the Remainder of the Week This is forecast by the NWS as a "once in a generation flood in the Lower Ohio Valley. The green tint is the geographic extent of the forecast flooding with this event. The boxes represent the highest stage currently forecast for the major  rivers. Purple is major or record flooding. Red is "moderate" flooding. The brown tint represents flood warnings already in effect. 

6:25pm These are rare and should be seriously considered in your plans into this evening.  3:55pm, a new tornado watch issued.  4:24pm Please get your shelter ready! If you live in a mobile home, you can find your nearest public shelter here . 

Catastrophic flooding is forecast for the pink area of western Kentucky during the next five days.   The red dots are where major flood is forecast to occur on major rivers with river gauges.  The blue is where "considerable" flooding is forecast. 

A tornado outbreak of strong tornadoes is forecast to occur today and tonight.  Hatching is where strong tornadoes are forecast to occur. The purple area has the highest risk. 

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 is the overnight tornado threat we've been talking about.  I am now providing additional updates on Twitter/X   @usweatherexpert .  --- original posting (still valid) --- Now until 7a Wednesday The tornado risk has decreased in Oklahoma south of I-40. 7am to Noon Wednesday For Wednesday morning, there is a significant chance of tornadoes in western and, especially, northern Missouri. It is unusual to have tornadoes during the morning....

Wednesday is going to be another day with the potential for destructive tornadoes.  You can find suggestions for your home tornado shelter and insuring that you receive warnings during the night,  here .  If you live in a mobile home and don't have a shelter at your mobile home park, you can find a map and list of public shelter s   here .  On my 4-point scale, here is the color code: Red, hatched = high  risk of strong tornadoes.  Yellow, hatched = enhanced risk of strong tornadoes.  Brown = significant risk of tornadoes.  Of course, I will update this forecast tomorrow morning. As far as timing is concerned, here is a general idea.

Late season snow forecast for the Upper Midwest. A foot of snow may fall in southeastern North Dakota. 

Once in a Generation Flooding Expected! The purple area over western Kentucky and adjacent areas is where catastrophic flooding is forecast to occur. The blue area is where major flooding is forecast. This forecast is valid from tomorrow until April 6.  The red dots represent river gages that are forecast to measure "above flood stage" conditions. Orange is minor flooding.  The #1 cause of fatalities in flooding is driving or walking into a flooded area! If you live in an area where flooding as occurred at one time or another in the past, remember:  Create a "go kit," that would include family heirlooms and other valuables, clothing for 3-4 days, medical needs (medicines, etc.). Make sure your car is completely fueled. Get some extra cash from the ATM. Keep your phone and laptop charged. 

Here's an updated tornado forecast made at 12:45am Tuesday. There is an enhanced risk of strong tornadoes in the yellow, hatched area.  There is a significant risk of tornadoes in the brown area. Any thunderstorms in the brown area, and especially, the yellow area have the risk of large hail. I'll cover that in an update later today.  Immediately below is a posting about tornado preparations since this is the first tornado situation of the year in Kansas.
