<br />r <br /> <br />thundershowers developed during the night of July 27 along the Front Range which produced heavy <br />amounts of precipitation. <br /> <br />On July 28, tropical moisture was present at all levels within the atmm,phere across the state. The <br />easterly surface flow of moist air continued as the cool front became quasi-stationary (Kelsch, 1997). <br />This large-scale scenario changed very little during the day. Thunderstorms developed along the <br />Front Range in the afternoon of the 28th. The thunderstorm cells formed a line and began moving <br />slowly toward the east-northeast away from the foothills. As the thunderstorms moved cast, they <br />produced a southeasterly outflow which enhanced the low-level upslope back toward thc foothills <br />(Kelsch, 1997). The regeneration of storm cells due to the southeasterly outflow was one process <br />working to generate the quasi-stationary storm complex. In addition, southwest-northeast bands of <br />convective enhancement appeared to join forces with the low-level southeasterly flow which may <br />have helped produce the excessive precipitation observed in Larimer und Weld Counties (Kelsch, <br />1997). <br /> <br />In general, the large-scale atmospheric condition described here-in set I he stage for the very heavy <br />precipitation that was observed across the state in late July and August. <br /> <br />Atmospheric scientists are further investigating the large-scale atmospheric conditions associated <br />with the 1997 flood season. Detailed meteorological analy"" will be available when these studies <br />are complete. This report does not attempt to duplicate those efforts. <br />
