STP 05-16-2015: Upper Trough on the Move, Another Day of Showers and Thunderstorms

Issue Date: Saturday, May 16th, 2015
Issue Time: 9:00 AM MDT

Summary:

Yesterday featured quite the array of weather, from sunny skies and warmth, to severe thunderstorms, and even snow over the western mountains above 8500 feet. As the upper trough moved east, its attendant dry slot worked in over the eastern half of Colorado, and combined with a developing surface low, acted to mix out moisture over eastern Colorado. This kept rain rates, and thunderstorm coverage, much lower than what could have been, and thus rain totals (and rain rates) were more of the light-to-moderate side of things. For a look at yesterday’s liquid precipitation totals, be sure and check out the radar-estimated precipitation map below.

As far as severe local storm reports are concerned, yesterday provided a fair amount of hail reports of 1+ inches. Those include:

1.50 inch: SE of Julesburg (Sedgwick County)
1.25 inch: 6 miles ESE of Fairfield (Phillips County), NW of Dacono (Weld County), 4 miles WSW of Arapahoe Park (Arapahoe County), and 5 miles NNE of Parker (Douglas County)
1.0 inch: Julesburg (Sedgwick County), 5 miles SSE of Greeley (Weld County), and 1 mile NW of Frederick (Weld County)

No flash flooding occurred yesterday.
