Flash Flooding Possible in the Southwest; Very Hot in the South and Northwest

Monsoonal activity will elevate the potential for flash flooding impacts especially in complex terrain, burn scars, and urban areas across much of the Southwest and Intermountain West along with the central and southern Rockies into next week. Very hot conditions cover much of the interior Northwest, south-central, and southeast portions of the CONUS into the weekend. Read More >

The start of "Meteorological Summer 2020" (June, July and August) continued the roller coaster type of weather pattern as the previous month of May across south central and southeast Colorado, with periods of warm and dry conditions followed by periods of cool and wet conditions, as a few weather systems moved across the state. On June 9th, measurable snowfall was recorded across portions of south central and southeast Colorado, especially across Northern El Paso County and the Palmer Divide. June also brought a few days of severe weather across the region, and produced localized areas of heavy rainfall. July of 2020 continued the roller coaster type of weather pattern through the first half of the month, with hot and dry conditions followed by cooler and wetter conditions, especially across the southeast plains, where a few frontal passages brought bouts of severe weather to eastern Colorado. The latter portion of July saw an increase in monsoonal moisture across the state, with cooler and wetter conditions experienced into the end of the month. August of 2020 saw its share of severe weather across south central and southeast Colorado, most notably on August 5th, when destructive hail of up to 2 inches in diameter pounded southwestern portions of Colorado Springs. However, most of August of 2020 will be remembered for being generally hot and dry, with several major wildland fire starts across northern and western portions of Colorado, including the Pine Gulch fire in western Colorado, which has grown to be largest wildfire on record in Colorado.

For the Summer of 2020 as a whole, above to well above normal temperatures were experienced across all of south central and southeast Colorado, with mainly below to well below normal precipitation, save for portions of the southeast plains, which saw at or above normal precipitation.   The following graphics indicate seasonal temperature and precipitation departures from normal across the state for the Summer of 2020.
