Update on Tuesday's Rain

As an area of low pressure out in the planes states continues to spin about and move east/northeastward, a trailing cold front will move through later tomorrow allowing for rain along and ahead of front.  The rain is expected to start after midnight and last through late morning/early afternoon in most areas.  Here's a snapshot from the RPM model, depicting what the radar will look like:

RPM radar reflectivity valid 6AM Tuesday 10/14

As with the last system, this system is moving relatively quickly, and coming in at a time where the atmosphere isn't "charged" so there's really no threat for heavy rain amounts.  Overall a good tenth of an inch to quarter of an inch of rain is possible, with higher amounts north of the Quad Cities.

After the front moves through, temperatures are cooling down!
