Dangerous Heat in the Western U.S.; Flash Flooding Possible Across Portions of the South

High temperatures in the 90s to 100s and warm overnight temperatures will continue across parts of the Interior Northwest, central California, and the Great Basin. Thunderstorms and heavy rain may produce scattered flash flooding across much of the Southern Rockies into the Southwest, particularly over sensitive burn scars in New Mexico, and across the Southeast into the Carolinas.

The start of "Meteorological Spring of 2019" (March, April and May) was a cool and wet across most of south Central and southeast Colorado, as periodic weather disturbances moved across the Rockies, bringing abundant  snowfall to areas over and near the higher terrain, especially along and west of the Continental Divide. This snowfall produced an unprecedented amount of avalanches across Colorado's "High Country" throughout the month of March. This pattern also produced an extremely powerful low pressure system across southern Colorado on March 13th, bringing strong and damaging winds and widespread rain to the southeast Plains, blizzard conditions over El Paso County, and dropping feet of snow over the mountains. The "bombogenesis" event of March 13th also set records as it produced the lowest surface pressure ever recorded (970.4 mb in Lamar) in the state, along with several records of the strongest wind gusts across southeast Colorado, including a record setting 96 mph wind gust at the Colorado Springs Airport. 

April of 2019 was roller coaster month for temperatures,  especially across the southeast Plains, as  weather systems moving across the Rockies brought periods of unseasonably warm weather followed by periods of unseasonably cool weather to the region. These systems also brought bouts of rain and snow, especially for areas over and near the higher terrain.  May of 2019 continued to be a roller coaster month for weather across the state, with a few spells of warm and dry weather, along with periods of unseasonably cold and strong weather systems bringing abundant rain and snow across the area, as well as bouts of severe weather across the southeast Plains. 

For the Spring of 2019 as a whole, near normal to below normal temperatures were experienced across south central and southeast Colorado. As for precipitation, generally above normal precipitation was experienced across the area, save for pockets of at and below normal precipitation  across the southeast Plains. 

The following graphics indicate seasonal temperature and precipitation departures from normal across the state throughout the Spring of 2019.

 

The preliminary average temperature for the Spring of 2019 in Alamosa was 42.7 degrees, which is 0.5 degrees above normal. Alamosa recorded 3.15 inches of precipitation throughout the Spring.
