Boulder was under a flash flood warning into Saturday night, with a high likelihood of more rain on top of an already saturated and flooded landscape through late in the day Sunday.
The Boulder area breathed a sigh of relief earlier Saturday under partly cloudy skies, but clouds built in as the day went on, bringing with them a few scattered showers and highs in the upper 70s.
There remained a chance of thunderstorms in the evening, with rain showers likely along with isolated thunderstorms possible after midnight.
Rain showers are likely Sunday, with a chance of thunderstorms. It will be cooler, with highs in the mid-60s and the chance of precipitation at 60 percent.
A flash flood watch, said National Weather Service program manager Byron Louis, would likely remain in place into early evening hours.
"The possibility of flooding will linger through the rest of the day, for the most part," Louis said.
Monday should mark the beginning of significant improvement, with temperatures in the mid-to upper-- 70s, and the chance of rain at just 20 percent. It gets even better after that, with temperatures near 80 and very little chance of rain.
"Once we get through this next system, we'll be in good shape, and then it looks completely dry, Tuesday through Friday," NWS meteorologist Scott Entrekin said.
Although the rain is expected to finally let up, the danger of flooding from water already on the ground remains.
NWS meteorologist Kyle Fredin said "pretty much all of northeast Colorado" is under a flash flood watch until Wednesday morning.
Fredin said the alerts concerning possible flood activity are subject to frequent revision.
"They've just been non-stop," Fredin said. "Another wave of watches and warnings could be coming up.
