Expect a few strong to marginally severe storms across the plains this afternoon with damaging winds and hail up to one inch in diameter. The strongest storms will mainly remain east of the urban corridor. The flash flood potential in the mountains is expected to be low today with only marginal moisture and instability along with decent storm motions. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Saturday through Monday will be a very wet period before a slight drying and warming trend will start on Tuesday. Storms that form Saturday through Monday will be strong with heavy rain likely in the mountains, foothills, and I-25 corridor. This may lead to flooding due to the very wet ground that will not be able to take much more water. The most likely day for flooding will be Sunday but the flooding risk will exist on Saturday and Monday as well. The recent burn areas will see an elevated risk of flash flooding each of those three days. Some of the storms on Saturday through Monday may reach severe limits with hail and damaging wind gusts being the primary threats. Tuesday through the end of next week will see scattered showers and storms form most afternoons. There may be a limited risk of burn area flash flooding each day with some storms producing small hail and gusty winds. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed across the northeast plains this afternoon, mainly sections east of the Interstate 25 corridor. Reports of hail and damaging winds will be appreciated. $$
