Strong storm moves in late Sunday night

The last week of September is going to bring in heavy rain and cooler temperatures.

PORTLAND, Ore. — The first day of astronomical fall brought in a thick cloud deck that kept us cooler from what we have been seeing the last few days. Highs on Saturday afternoon topped out near 70 degrees around the metro area.  A system will be moving through Saturday night that could bring in some light showers around the valley, but a stronger front will be working its way through late Sunday night and into Monday morning with heavy rainfall. 

Rainfall amounts from Sunday night into the middle part of next week could easily go over 2" of rain just in the valley alone. Those rainfall amounts could get even higher with the threat of thunderstorms in the for the early part of next week too. 

Even though the first week of fall is going to be cool and wet, some models are pointing to warmer weather by the early part of October with highs around the low to mid 70s. 

Enjoy the rest of your weekend,
