Severe Storms for the Rockies Front Range, Sunday
Lingering energy behind the cold front is going to bring enough instability for storms to develop along the front range of the Rockies in Wyoming and Colorado, Sunday. The coverage area for the Marginal risk, issued by the SPC, is mainly in Colorado for isolated but strong storms.
Damaging wind and large hail are the main threats. Downdraft wind could be nearing 60-70 mph as the storms move and hail could be upwards of 1″ in diameter. This would be the size of a quarter if large stones develop.
By this afternoon, scattered storms start to develop along the I-25 corridor in southern Wyoming and in the eastern plains of Colorado.
The movement of the storms in Wyoming will be to the southeast while the storms in Colorado will be tracking from west to east.
Stepping into the evening hours, storms are likely to hold their structure even past sunset in Colorado while moving into Nebraska and Kansas.
By midnight, the threats will be a lot lower when it comes to severe concerns but steady rain is still going to be tracking along the I-70 corridor.
The storms are looking to put down 1″ to 1.5″ of rainfall accumulation. The activity should be over by the time we get into Monday morning.
