— Flooding is NOT expected today
As shown in the visible satellite image, below, a pronounced disturbance is currently moving into the Central Rockies from the northwest. Although it will produce mainly an increase in clouds for Colorado today, it is expected to cut off from the main steering flow by tomorrow. In turn, depending on what exactly transpires with it over the next 3-7 days, it could lead to some more interesting weather for us in the days ahead (see this afternoon’s Outlook for more info).
For today, expect slightly above normal afternoon temperatures along with partly to mostly cloudy skies by afternoon. Isolated, higher-elevation rain and snow showers are possible this evening and into the early overnight hours as some mid-level moisture gets pushed upslope over our Rockies. But very little precipitation accumulation is expected. Thus, there is NO flood threat today.
