The chances of a tornado forming are low, but not zero.
Tornadoes are ranked on the Fujita Damage Intensity Scale as follows:
F0 – F1 Weak Tornado
F2 – F3 Strong Tornado
F4 – F5 Violent Tornado
Tornadoes in Utah are rare, but the Beehive State averages about two tornadoes per year, with only one F2 or stronger tornado every seven years.
Thunderstorms will likely develop this afternoon and evening. Isolated pockets of heavy rain with a chance to see some low-end supercells.
