STP 07-30-2015: Subtropical Moisture Increased, but the Effects were Limited

Issue Date: Thursday, July 30th, 2015
Issue Time: 9:00 AM MDT


Yesterday was another pleasant day overall, providing for a great mid-week bridge to the downhill side of the work week. While subtropical moisture streamed overhead, it was again the general lack of instability and mid-/upper-level dynamics that kept showers/thunderstorms on the weak side. Mountain locations along the Front Range, Central Mountains, and Southeast Mountains experienced the most coverage of thunderstorms where orographic effects helped make up for the lack of other support. Also, the Raton Ridge and Southeast Plains along the CO/NM border received a few pockets of rainfall during the afternoon and evening hours, as stronger storms graced northern NM.

Rain totals and, for that matter, rain rates, were generally low. As of 7 AM, the only totals reported greater than 0.1 inches by CoCoRaHS observers were Chaffee County (0.77 inches) and Teller County (0.36 inches).

There weren’t any severe storm reports from yesterday, and no flash flooding was observed.
