FTB 05-24-2017: Sunny And Warm, Though Only For A Day

Issue Date: Wednesday, May 24th, 2017
Issue Time: 10:08AM MDT

— Flooding is NOT expected today
— Elevated fire danger across the Southwest Slope

It is a “severe clear” morning across Colorado and surrounding states on this Wednesday. Precipitable water values have dropped to 0.4 inches or lower statewide as a transient ridge builds into the region, if only for a day. Subsidence will allow for much warmer temperatures today than the past few days. Even so, only slightly above normal temperatures are expected, a testament to just how chilly the weather has been over the past week or so.

Moving our eyes farther northwest (see water vapor image below), we see across southwest Canada and the US Pacific Northwest the disturbance that will affect our weather starting on Thursday. The first wave of dynamics from this storm will move into northwest Colorado later this evening and into the overnight hours. With little moisture to work with, only light rain and snow showers are expected. Things will change markedly tomorrow as moisture returns in abundance. Stay tuned to tomorrow’s Flood Threat Bulletin for details.

For today, flooding is not expected statewide.
