— A LOW<\/strong> flood threat has been issued for the Southeast Mountains, Northern Mountains, Northeast Plains, Raton Ridge and Southeast Plains<\/em><\/p>\n
Today the 500mb High will continue to strengthen, and the majority of the state will be under the influence of the clockwise flow. Over the far southeast corner of the state, there’s still some westerly flow with yesterday’s front draped over the central eastern plains. Monsoon<\/span> moisture has started to fill in statewide as shown by dew points<\/span> > 50F over eastern Colorado and at a few stations over the southwest corner. PW<\/span> has risen to 0.60 inches over Grand Junction and 0.92 inches at Denver. Dew points<\/span> should remain high throughout the day as the surface flow will be favorable for moisture advection<\/span> in a post-frontal, upslope flow environment. With slow steering flows under the building ridge and some mid-level energy in the area, widespread<\/span>, heavy rainfall producing storms are forecast today. Additionally, a couple severe thunderstorms<\/span> will be possible over the eastern plains.<\/p>\n Storms over the mountains will pop by early afternoon and are forecast to be widespread<\/span> in nature. It is likely that outflow boundaries<\/span> will help to produce additional storm coverage in the moisture-rich environment. A couple stronger thunderstorms possible with the main threats being hail and brief outflow<\/span> winds. Best chance for these storms will be over the Southwest Slope high terrains and southern Front Range. A MODERATE flood threat has been issued for these areas due to a higher likelihood for stronger and training<\/span> storms producing heavy rainfall.<\/p>\n Rainfall might not be as easy to come by over the adjacent plains today as Denver’s sounding this morning showed a decent cap<\/span>, which could inhibit convection<\/span> this afternoon. Morning model guidance has also quieted over the far eastern plains. Should an outflow boundary<\/span> from a storm to the north or enhanced convergence from a developing Denver Cyclone<\/span> be able to trigger convection<\/span> with the eroding cap<\/span>, a couple severe thunderstorms<\/span> may be possible over this forecast region later this afternoon and evening. This would also hold true for any storms that track into the state off the Cheyenne Ridge. On top of severe weather, these storms will also be capable of producing very heavy downpours, so a LOW flood threat has been issued.<\/p>\n Finally, further south over the far Southeast Plains, it is possible that a convergence boundary may move northward from New Mexico and Oklahoma late this afternoon. It may be able to help break the cap<\/span> over the area, if it does so, a couple severe thunderstorms<\/span> may be possible. In addition to hail and strong outflow<\/span> winds, heavy rainfall would be likely due to dew points<\/span> in the low to mid-60s. Less confidence that the boundary will make it northward into the state, so only a LOW flood threat has been issued.<\/p>\n For more information on today’s flood threat, see the map below.
