Particularly hazardous thunderstorms are possible Friday for the Front Range and High Plains. Hazardous thunderstorms are possible for portions of the Great Plains, Central US, Utah, and Arizona. Heavy rain is possible for the Central US.

Front Range & High Plains/Great Plains & Central CONUS:Strong low-level moisture surging northward into the Front Range and High Plains region will interact with favorable upslope flow and bring the potential for strong to severe thunderstorms across the region on Friday, mainly during the afternoon and evening hours. Large hail will be the main severe threat, though some of the more organized thunderstorms could produce damaging winds and perhaps an isolated tornado. Further east, across the Central Plains and into the central U.S., thunderstorms are expected to be ongoing Friday morning. This activity should mostly be sub-severe, but storms could re-intensify during the afternoon and evening hours. Damaging winds and moderate to large hail will be the main threats.

Central CONUS: Multiple rounds of showers and thunderstorms or possibly a complex of thunderstorms are expected to move eastward across eastern Missouri, southern Illinois, and southwestern Indiana Friday morning through evening. A narrow swath of heavy rainfall across this region will be possible and could produce accumulations of 1-3 inches.

Utah & Arizona:An upper level low pressure area is forecast to move into the southwestern United States on Friday. Thunderstorms are expected to develop across portions of southern Utah and Arizona, especially during the late morning through early evening hours. A few of the stronger storms could produce gusty winds and hail.
