FOX 12 FORECAST - COOLER SUNDAY, LIKELY DRY UNTIL EVENING

Saturday, September 25th, 4:45 P.M. 

It has been another very warm late September day, temperatures are peaking in the low-mid 80s west of the Cascades.  The coastline is much cooler today, mainly around 60 degrees because the dry/warm easterly wind is gone.  I expect cool marine air to surge inland this evening, and that leads to a much cooler day Sunday.  Temperatures drop back to normal under partly cloudy skies Sunday.

A weak weather system arrives tomorrow evening along the I-5 corridor.  The first real chance for showers is around 5pm or so, but by 8-10pm we expect widespread light rain everywhere west of the Cascades.  Showers arrive much earlier (midday) along the coastline for a gray day out there.  A 2nd system moves inland later Monday for more showers.  Cool showers continue Tuesday.  In general you can expect rain at times from tomorrow evening through Tuesday evening with a total of 1/2” to 1” in the metro area.  We may see a thunderstorm at some point Monday or Tuesday afternoons.  Snow will also drop as low as 6,000’ Tuesday which is roughly the timberline around Mt. Hood.  This should finally finish off the fire season in the Cascades as well with another 2-3” rain on the way up there.

Other than some light rain Thursday, the 2nd half of the week and next weekend turn drier.  The first weekend of October might turn out to be quite warm.
