— Flooding is NOT expected today
Today’s precipitable water (PW) chart, shown below for several Colorado stations, shows everything one needs to know about today’s heavy rainfall chances. PW has sharply fallen over the past 24 hours and is not expected to recover today. Thus, despite the presence of an upper-level trough to the west, the odds of heavy rainfall are slim to non-existent. Instead, we expect gusty winds and scattered showers with perhaps a thunderstorm mixed in especially over eastern areas.
