A cold front pushed through eastern Colorado overnight, with a moist and unstable airmass spreading across the region in its wake. This will set the stage today for areas of showers and thunderstorms to develop across much of eastern Colorado, with a widespread threat for locally heavy rain developing. The best chances for heavy rain were along and west of the interstate 25 corridor and across the far southern sections of the southeast plains, near the frontal boundary. With the heavy rain, an elevated threat for flash flooding is expected across the burn scars and over areas already saturated from recent heavy rains. Persons living in or near these areas should remain weather alert. Area rivers are already running high from recent rains. Additional rains today over the Pikes Peak and lower Arkansas River Valley could lead to additional spikes in river levels. Those planning outdoor activities near the rivers should be prepared to move to higher ground should the ne! ed arise. Area temperatures will be below average across southeast Colorado today, with highs generally warming into the 60s and 70s, with some 50s over the higher mountain locations.
