NEAR ST LOUIS.
WARM...MOIST SOUTHERLY WINDS STREAMING NORTHWARD AHEAD OF THE LOW
WILL UNDERCUT A BAND OF FAST...COOL...WEST-SOUTHWESTERLY JET STREAM
FLOW.
THUNDERSTORMS ARE NOW FORMING ALONG AND AHEAD OF THE COLD FRONT
PROGRESSING EAST ACROSS THE OZARKS AND MID MISSISSIPPI VALLEY.
OTHER STORMS WILL CONTINUE TO FORM OVER A LARGE AREA OF
MOIST...UNSTABLE CONDITIONS FROM EASTERN ARKANSAS AND SOUTHEAST
MO...ACROSS PARTS OF SOUTHERN ILLINOIS...SOUTHERN INDIANA...WESTERN
AND CENTRAL KENTUCKY...AND WESTERN TENNESSEE.
CONDITIONS WILL ONCE AGAIN BE FAVORABLE FOR THE DEVELOPMENT OF
LONG-LIVED ROTATING THUNDERSTORMS THAT COULD PRODUCE FAST-MOVING AND
POTENTIALLY DEADLY TORNADOES...IN ADDITION TO LARGE HAIL AND
DAMAGING WIND. THE STORMS MAY EVOLVE INTO AN EXTENSIVE BAND THIS
EVENING...WITH AN ASSOCIATED THREAT FOR DAMAGING WIND... HAIL...AND
TORNADOES SPREADING EAST ACROSS THE REMAINDER OF THE OHIO VALLEY AND
INTO PARTS OF THE TENNESSEE VALLEY LATER TONIGHT.
STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS POTENTIALLY

REVIEW SEVERE WEATHER SAFETY RULES AND TO LISTEN TO
RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR POSSIBLE
WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.

Those poor folks. That late winter is giving a double-whammy.
And then the pattern will reload for another outbreak in my neck of the woods on Memorial Day where we’ve already had one touchdown in Minneapolis last weekend. Could be some across NE-IA-northern IL-lower MI Sunday then shifting to the eastern Daks-NE-MN-WI on Monday.
And New Englanders brag about having such bad weather.
Perhaps that “End of the World” prediction wasn’t wrong. Look at all that Rapturing going on
I do hope everybody gets to “batten down the hatches” and comes through safe and sound.

All we can do is pray, – But if our prayers are no heard, the we l have to act, then why not establish, right now, what that action may or may not be?
New Englanders do not brag about their bad weather. We cite its unpredictability, our little New Hampshire mountain does have the worse weather in the world, year-in-and-year-out, and if you do not like the weather hereabouts, you only need to wait awhile. It’s been 58 years since a major tornado here, true, but it still holds some records, I believe, for duration, length of the track and the like. Just setting the record straight.
KFVS Channel 12 is in the thick of things at the present time. There are tornadoes on the ground in Missouri and Southern Illinois with large hail. There are tornadoes currently reported North, South, and Southwest of us right now. Families are taking shelter here.

So long as the cold pool conveyor is in place, this will continue. I have seen this movie many times before, although this year is unreal in terms of duration.

Funnel Cloud 6 miles northeast of Tamaroa, Illinois
Keep an eye out and be ready to duck and cover, ya’ll.
No joking or smilies about that. In my neck of the woods, we’re under a watch right now and a few miles up the road they’re under a warning. I think my area is going to get passed by on either side by the strongest cells.
Expected and received. Nasty weather.

This is about 150 miles east.
Any word from ppl/viewers/posters in Indiana?

Indy 500 is this weekend too (Sunday)
Sirens reported going off in Marion county (Indianapolis) by TV8.
We have live tornadoes on the ground in California. North of Chico and heading NE.
One was chased by a father and his boy (who was on the phone w/KHSLTV-Chico).
Trees torn up, barn roofs torn off, tractor damaged, etc. Mostly in farmland.
1 mile South of Butte College heading towards Table Mountain.
So that’s where Anthony has been …
BTW, listening to TV8 I haven’t heard much (any!) reference to either ‘storm chasers’ or storm spotters – I guess these ‘Northern states’ don’t make much use/any use of that resource (heavy reliance on RADAR and public/law enforcement reports; have they had NWS spotter training like ham radio spotters receive in Texas? Years ago I attended a spotter/Skywarn class given at Mountain View College in Dallas by Alan R. Moller, now retired, from the NWS office in Ft. Worth).
The stations in DFW will have live camera video from in-car units and a few professional storm chasers as well as these storms unfold in the DFW area.

Here’s an appreciable hail video.
This might be of some interest, the historical origins of SKYWARN and associated training (due in no small part to Alan Moller and his work among others):
Storm Spotting and Public Awareness since the First Tornado Forecasts of 1948

ABSTRACT (partial excerpt)
The history of storm spotting and public awareness of the tornado threat is reviewed. It is shown that a downward trend in fatalities apparently began after the famous ‘‘Tri-State’’ tornado of 1925.
Storm spotting’s history begins in World War II as an effort to protect the nation’s military installations, but became a public service with the resumption of public tornado forecasting, pioneered in 1948 by the Air Force’s Fawbush and Miller and begun in the public sector in 1952.
The current spotter program, known generally as SKYWARN, is a civilian-based volunteer organization.
Responsibility for spotter training has rested with the national forecasting services (originally, the Weather Bureau and now the National Weather Service). That training has evolved with (a) the proliferation of widespread film and (recently) video footage of severe storms; (b) growth in the scientific knowledge about tornadoes and tornadic storms, as well as a better understanding of how tornadoes produce damage; and (c) the inception and growth of scientific and hobbyist storm chasing.

The paper linked above contains some interesting charts including:
a) count of tornadoes historically/year (increasing, with a notable jump indicated in the 1950’s. Post WWII modified military RADARa came into use for meteorology before the advent of the dedicated model WSR-57 so-named for its adoption in 1957 as the national standard NWS meteorological RADAR)
b) fatalities/yr (decreasing) among others.

A good place to keep up on information on the recent tornadoes is a site called Radio Reference.com, police/fire and emergency services. If you have family out there, it is a good place to find and listen for information on their whereabouts. There is also an option to listen to the storm chasers as they chase the tornadoes, but I haven’t picked up any radio chatter on that feed. I guess there are a little busy at the moment.
