Three Days of Tornado and Severe Thunderstorm Threat

Outside of some small areas of the northern United States, the tornado threat has been quite limited (for the first half of June) the last week. That changes to a more normal pattern through Wednesday.

Today and Tonight
Below is the tornado risk map. Brown, 5%, is the significant threshold. Please note it includes the Denver area as well as I-70 from Denver to Goodland, Kansas.
NWS Storm Prediction Center
Below is the hail risk map. Yellow, 15%, is the significant threshold for 1" or larger hail. In addition to a large area where hail is expected, the hatched areas is where hail could be larger than 2 inches.

Tuesday and Tuesday Night

SPC issues combined risk maps for the second day of the forecast.
For Tuesday, the biggest risks appear to be damaging thunderstorm winds plus some isolated tornadoes.

The primary threat Wednesday is thunderstorms with wind gusts to 60 mph.

I'll update all of this the next three days.
