STP 05-26-2017: Heavy Rain, Wind, Hail, Tornadoes All In The Mix On Thursday

Issue Date: Friday, May 26th, 2017
Issue Time: 10:45AM MDT

Summary:

A large disturbance moving in from the northwest began to affect Colorado on Thursday. Showers and thunderstorms were scattered west of the Continental Divide, and much more numerous to the east, especially across the Northeast Plains. Most activity was fairly benign with rainfall up to 0.5 inches commonly seen. However, a few storms farther east caused large hail (up to 3 inches near the KS border!), a few tornadoes and heavy rainfall exceeding 1.5 inches per hour. Highest observed rainfall amounts were about 0.75 inches. However, in rural areas of Washington and Yuma counties, heavier rainfall likely occurred.

In addition to the precipitation, strong winds affected many locations yesterday. Some wind damage was observed over the Southwest Slope, while elsewhere wind gusts in the 45-60 mph range were common across higher elevation locations.

A high pressure ridge briefly setup shop across Colorado on Wednesday, providing plenty of sunshine along with some locally gusty winds. Many lower elevation locations approached the 90F mark, notably Pueblo and Grand Junction. A few light rain and snow showers moved into northwest Colorado overnight as a large disturbance approached the region. However, with a dry atmosphere only a few hundredths of an inch of precipitation was observed.

STP 05-24-2017: Isolated Showers, But Overall Pleasant Tuesday

Issue Date: Wednesday, May 24th, 2017
Issue Time: 10:20AM MDT

Summary:

After a long stretch of active weather, Tuesday was much quieter statewide. A few afternoon cumulus clouds were able to form given the high soil moisture. However, these managed to produce only isolated rain showers mainly along and east of the Continental Divide. Lucky locations received up to 0.1 inches of rainfall. For everyone else, it was a pleasant Tuesday.

In anticipation of the upcoming snow melt, this morning’s check of the statewide snowpack, below, shows conditions that are almost exactly in sync with the long-term climatology. We will be monitoring temperatures and precipitation over the coming weeks to inform of potential snow-melt related flooding.

STP 05-23-2017: Another Round Of Afternoon and Evening Showers

Issue Date: Tuesday, May 23rd, 2017
Issue Time: 9:40AM MDT

Summary:

Active weather continued across most of Colorado on Monday, as an upper-level disturbance and accompanying surface cool front moved across the state from the north. With ample early heating, even a few weak thunderstorms got into the mix especially across southern areas.

Precipitation started in the early afternoon hours along the Wyoming border, then spread rapidly southward. Rainfall amounts in the 0.15 to 0.30 inch range were typical. However, over the Palmer Ridge, Southeast Plains and Southeast Mountains a few locations received closer to 0.5 inches of rainfall. Gusty winds up to 60 mph accompanied at least one storm along the Kansas border in the mid-afternoon, prompting a brief severe thunderstorm warning. For everyone else, just another orderly rainfall event in what is becoming quiet an active May.

Snow mixed in with the rain above 9,000 feet (lowering to about 7,500 feet by evening). However, only limited accumulations were reported, generally below 3 inches.
