STP 06-27-2017: Scattered Showers over Southeastern High Country and Plains

Issue Date: Tuesday, June 27th, 2017
Issue Time: 10:27AM MDT


The persistent weather pattern, marked by a weak upper-level ridge centered west of Colorado, continued its hold again yesterday. West of the Continental Divide, it was extremely warm and dry with Grand Junction reaching a high of 98F. East of the divide, the day began with very high low-level moisture. Dewpoints were 60F at Pueblo and surrounding regions at 9am. Over the Palmer Ridge and Northeast Plains, much of this low-level moisture quickly mixed out in the late morning hours limiting the number of scattered storms in the afternoon. However, a storm that formed in Wray reported ping pong sized hail around 4pm, causing broken windows and was accompanied by a small funnel cloud.

Upslope flow triggered a handful of severe thunderstorms storms south of I-70 and over the Southern high country where high moisture did not mix out. Near Durango, a spotter reported 0.61 inches in a 25 minute period. Most other storms dropped 1-1.5 inches of rain with storm centers closer to 2 inches. Under the stronger cells, 1-1.75 inch hail was also reported. There were two flash flood warnings and advisories issued over burn scars due to the slow moving storms. One warning over the Junkins Burn Scar and an advisory for the Waldo Canyon burn scar outside of Colorado Springs.

No flooding occurred yesterday (at least as of this morning). Please see the STP map below for a look at 24-hour precipitation totals.
