Street flooding was reported in some parts of Aurora, where as much as 1.5 inches of rain fell in about 30 minutes early on Thursday afternoon.

In Northern Colorado, a Flash Flood Warning was issued for the Cameron Peak Fire burn scar. The National Weather Service said rainfall rates there were exceeding 2 to 2.5 inches an hour. That warning was allowed to expire.

ALERTS: Latest Colorado weather alerts

Most of eastern Colorado can expect a half-inch to an inch of rain from this system, though some higher amounts are likely in southeastern Colorado.

The flood threat should be relatively low in northeastern Colorado, thanks to our relatively dry week so far and much lighter rainfall totals compared with last week. However, some pockets of flooding could be possible, especially in low-lying and flood-prone areas.

The rain should wrap up later Friday, and it looks like we'll have an overall drier weekend with only isolated storm chances both days.

Any rain at this point will only add to the list of rainfall records that eastern Colorado has set over the past few days.

Denver has picked up nearly 5 inches of rain so far this month, putting the city on pace for its wettest month on record. Some parts of the metro area saw more than 7 inches of rain during an exceptionally wet three-day period last week.

This week's rain will probably be enough to push Denver's monthly rainfall total well over 5 inches, marking one of our wettest months ever recorded with still nearly two weeks left in the month.
