| Message 1’s will be allowed to expire at 2:00 AM as the threat for heavy rainfall from potential thunderstorms has diminished. Scattered to widespread light to moderate rain showers will continue likely overnight and produce minor runoff but flash flooding from heavy rainfall is not expected. Creeks and streams will be running high area wide due to rain this evening and overnight with additional rain showers into tomorrow morning. Rainfall amounts through 1:30 AM in the District typically ranged from 0.75-1.50” with isolated higher amounts under thunderstorms and another 0.25-0.75” of rain is possible through mid-morning Thursday with additional rain through the afternoon and evening. Rain showers will continue to impact the District on Thursday as a low pressure system churns to the S/SE of Colorado with thunderstorms possible once again from late morning into the early evening capable of producing heavy rain. The strength/severity of the storms is expected to be weaker than Wednesday. Due to all the rain recently, the ground is becoming saturated and it may not take as much rain during the day Thursday to produce excessive runoff and Message 1’s are expected to be issued once again. |
WORST CASE SCENARIO: Weak to moderate thunderstorms are able to develop with the potential for heavy rainfall of 0.3-0.8" in 10-30 minutes.
