Possible Freezing Rain, Flooding Concerns

Cold east winds, blowing out of the Gorge to set the stage for possible Tuesday morning freezing rain in Portland and Salem.   

Precipitation is expected to return early Tuesday morning and may fall as freezing rain, depending on temperatures.  Hours of freezing rain are possible into early afternoon and possibly longer near the gorge in places like Camas, Troutdale and Gresham.  Ice will be possible at elevations near and lower than 2,000 feet.  During the afternoon, south winds should bring warming temps, changing most of the valley to rain.

The Gorge will likely see a bad ice storm with 24 hours of possible ice accumualtion from freezing rain Tuesday into Wednesday afternoon.  Significant ice accumulations of .75" are expected.  Conditions could get bad enough for I-84 closures.  

Flooding rains and rapid snow melt continue to be a concern.  A FLOOD WATCH is posted for much of our region.  Inches of metro valley rain will fall Tuesday through Thursday. The metro valley could see 2-3" of rainfall, while 3-5" fall at the coast and 4-7" hit the Coast Range.  Rising snow levels to 8,000' will melt mountain snowpack while heavy rains fall.

 Keep updated as weather will be a top story through mid-week.

Mild February, early spring possible

By Rod Hill on 03-Feb-18 17:45.

The outlook from the National Weather Service calls for above normal temperatures for Portland during the month of February.  The outlook for rainfall is less confident but leans toward drier than normal precipitation.  Forecast models also point towards warm and drier than normal weather through the first 20 days

Triple treat for January’s second full moon

January’s second full moon will be a triple treat: it will be this month’s second full moon; the second perigee full moon; and best of all, there will be a total lunar eclipse!

Rod Hill's Winter Outlook 2017-2018

By Rod Hill on 25-Oct-17 20:20.

Like many forecasters that attempt long-range, seasonal forecast, I rely heavily on the projected Enso Cycle, which is a reference to projected water temperatures in the equatorial region of the Pacific Ocean.


Saturday Flooding Concerns

By Rod Hill on 20-Oct-17 10:40.

Forecast models show a long stretch of steady, heavy rainfall arriving Friday overnight and continuing into early Sunday morning.  New rainfall on top of what fell Thursday could equal 7" or more over the mountains (snow levels will rise back above 7,000 feet), 3-4" or more at the coast


Mt. Hood First Snowfall

By Rod Hill on 19-Sep-17 09:46.

Mt. Hood picks up the first snowfall of the early fall season!  Timberline Lodge at 6,000' reports .27" of total moisture from Sunday night through Monday night.  Surface reports show 2-3" of wet snow on the ground.


Hot back half of summer

By Rod Hill on 26-Aug-17 10:13.

Portland likely to see 90 degree heat this weekend with temps Sunday rising to near 100 degrees. As of Saturday morning, August 26th, PDX has hit 90 or better 15 days.


Rare heavy mid-May snowstorm

By Rod Hill on 17-May-17 10:35.

A rare snowy morning in May at Timberline Lodge. Not rare because of the snow, but rare because of the depth. According to auto-snow weather stations at 6,000’, Timberline has 28” of new snow over the past 36 hours! The Monday night - Tuesday night snowstorm hit Mt.


Trying to reach 70 degrees.

By Rod Hill on 21-Apr-17 07:38.

After a chilly 30 something start, much of the Willamette Valley and southwest Washington will warm to near 70 degrees this afternoon. Sunny skies and developing east winds will bring the warmth. Compared to April of 2016, we have been forced to hold our patience this spring for the arrival of warm weather.


February all-time record for rain in jeopardy

By Rod Hill on 20-Feb-17 08:15.

Heavy rain on this Monday morning, February 20th, has pushed total rainfall at PDX over 9.00" for the month and into 2nd place on the all-time February wet record list! Less than an inch of water is needed to break the all-time February rainfall record of 10.03" set back in 1996.


East winds to bring snow or ice

By Rod Hill on 31-Jan-17 07:46.

Cold east winds becoming gusty Tuesday night and blowing 40-50 mph near the gorge Wednesday and Thursday will set the stage for more winter weather over the Portland and Salem metro areas.  At this point, any moisture before Thursday night will be light and scattered, meaning no problems are expected.
