The mid-level ridge today moves ever so slightly to the west near the Four Corners. The slight movement will allow for an increase in shower/storm activity to reach the Plains from the higher terrain, as opposed to yesterday in which most storms resided over the High Country. Though, any storms will be limited rain producers given weak flow. Highs today …

Today's pattern is very similar to Friday, except for a warmer airmass over the area. The deepest moisture and lift/forcing continues to be located over the higher terrain west of Denver and over the south/southwest part of the state. To that end, we can once again expect the best chance of any storms today over the High Country and especially …

GOES-East mid-level water vapor imagery this morning shows that high pressure is situated over northeast Texas. Clockwise flow around this high is currently driving a highly visible pipeline of monsoon moisture into …

This is a textbook pattern you would see in a meteorology textbook of heavy rainfall potential, especially for the intermountain West. At 250 mb, there is a jet streak positioned west-east from Idaho into the Dakotas. To the south, …

Aweak but noticeable cold front slides south this afternoon from Wyoming and Nebraska. Ahead of the front, temperatures will again be hot in the mid to upper 90s. The approach of the front, however, will usher in cooler temperatures on Sunday, a welcomed change, but also widespread showers/storms this afternoon/tonight.
