STP 06-26-2015: One Hail Of A Day

Issue Date: 6/26/2015
Issue Time: 9:03AM

Active weather continued across the state on Thursday, as unseasonably high low-level moisture levels produced many a thunderstorm. Although there was plenty of heavy rainfall to go around (more on that later), the theme of Thursday was: hail. Almost every single strong thunderstorm deposited hail. By far the most menacing of the storms was the cell near Keenesburg that produced multiple reports of tennis ball size, or 2.5 inch diameter, hailstones. Many broken windows were reported, though perhaps Mother Nature spared us the worst with the storm traveling over relatively sparsely populated areas.

Heavy rainfall was also observed across many parts of the state. Thankfully, most of the heavy rainfall occurred in very short spells, on the order of 15-30 minutes due to a general lack of wind shear. The highest observed 24-hour totals came in from the Northeast and Southeast Plains were Kit Carson and Prowers counties received over 2 inches. However, short-term heavy rainfall also occurred over the San Juan mountains and the Grand Valley, where many locations picked up 0.25 to 0.75 inches over a matter of 15-45 minutes.

Meanwhile, without widespread rainfall, the very high river levels continue to slowly fall across the state. This morning, only one gage officially remained in Minor flood stage: the Arkansas River at La Junta.

No official reports of flash flooding were received yesterday. For estimated rainfall in your area, be sure to check out the rainfall map below.
