Of course, the purpose of this chase wasn't to find a tornado but to do some field testing. That said, it would have been nice to bag one of the large tornadoes in northern Kansas such as the one below.
Tomorrow still looks like a major severe weather event. Please stay tuned.
How do they determine F-rating on tornadoes that stay in open fields? Since wind speed is usually determined by damage sustained (from my understanding) - in areas where there are open fields and damage cannot be assessed, how do they determine the tornado rating? Seems like the one near Cunningham yesterday just spun itself in one place for quite awhile, which would also be different damage than a quickly-moving tornado.
If there is a mobile Doppler, they can use those winds as they did for Wichita's tornadoes a week ago Sunday. Mobile Dopplers are near the large tornadoes a surprisingly large percent of the time these days.
More heavy rain (snow in the mountains) forecast. Rains have already begun over the southern two-thirds of the state. See 3:15pm radar below. In addition, there is small risk of a tornado, especially tomorrow morning, in coastal areas of Southern California, shown in dark green.
7am Sunday Unfortunately, the forecast is on track. Heavy to, in spots, torrential rain is falling in southeast California and parts of Arizona. Flash flood watches and warnings are in effect. Please check with your local trusted source of weather information in order to make sure you have the latest information for your home or business. Again, I strongly discourage travel today and tomorrow. 5:15pm Saturday This is a terribly serious situation as the crest will be very close to the record stage! Many more evacuation orders will be issued. It is vital to have a "go kit." Scroll down to the link to show you what to gather. 12:15p: After I prepared the forecast below, an updated rainfall amount forecast for Arizona came in. More than 8" of rain is forecast to fall in there next three days! This may cause catastrophic flooding in a few spots with widespread serious flooding. Please see preparedness recommendations below. -- original post -- This is the flash flood ...
The tornado forecast is unchanged from yesterday. The brown area has a significant risk of tornadoes and the hatching indicates they could be strong. During the next three days, more than five inches of rain is forecast to fall in Iowa (orange). The result is a serious flood risk over Iowa and into northwest Missouri in the dark blue. In the pale blue, there is a lesser flood risk.
On the other hand, a spring drive thru the beautiful Gyp Hills is always worth a trip.
ReplyDeleteLove the Gyp Hills.
ReplyDeleteAny preliminary data on the Bennington area tornado? It sure looked like a monster on radar and in the social media photos I've seen.
ReplyDeleteNo. NWS hasn't looked at it yet.
