Warming temps, heavy rains next week to bring flooding concerns

By Rod Hill on 2017-01-13

All forecast eyes are on rising snow levels to 6,000 or 7,000 feet next week, along with 50 degree valley temperatures and inches of rain. The combo may be more than enough to cause high water problems, including river flooding.  

Forecast models show likely rain returning Monday night, falling steady all day Tuesday as warmer air returns and heavy rains Wednesday as a Pacific front pushes inland. Valley rain totals Monday night through Thursday could reach 2-3 inches, while the mountains pick up 5-6 inches or more. The warm, wet combo would quickly melt all of the valley snow and much of the Coast Range snow pack as well as lower elevations of the Cascades.  Rapid rises in rivers & streams should be expected.  Stay updated with the forecast here at PortlandWeather.com

GRADUAL WARMING FOR SOME, BUT NOT ALL

By Rod Hill on 2017-01-08

ICE STORM WARNING IS IN EFFECT

Expecting a checkerboard pattern of valley warming today.   Early this morning, temperatures have climbed above freezing at PDX, Hillsboro, Beaverton and Estacada to name a few locations. 

Much of the Portland metro will continue to see freezing rain showers this morning and possibly into the afternoon.   Windy areas on the east side are most likely to see ice accumulation through the day. East winds are gusting 40-50 mph near the gorge and 15-30 mph over downtown Portland.  

The warm up timing is a tough call.  Please check conditions before traveling. 

A WINTER STORM WARNING continues for the gorge where temperatures will hold in the 20s today with ice and snow.

SNOW & ICE STORM THIS WEEKEND - JAN 2017

By Rod Hill on 2017-01-06

Watches are posted from Longview to Portland to Eugene for a weekend Winter Storm, bringing snow and freezing rain accumulation.  Look for a period of increasing snow to begin Saturday afternoon, changing to freezing rain toward evening.  Ice accumulation will be likely Saturday overnight and Sunday morning for much of the region.  Areas near the Gorge may see Winter Storm conditions last into Monday.  Other locations, such as Salem will see Sunday warming and all moisture change to rain. 

In general, 1-3" of possible snow is in the forecast Saturday afternoon into early evening.  A transition to freezing rain Saturday night will bring ice accumulations of .25 - .75", coating trees, powerlines and roadways. If true, the valley would see a major ice storm, lasting well into the day Sunday for areas near the gorge. 

The central Gorge, including Hood River will see mostly now, with 6-12" expected!  West Gorge cities such as Corbett could see 2-5" of snow with an inch of ice accumulation on top.  Coast Range cities will see 3-4" of snow with .25-.75" of ice coming Saturday night. 

All areas should plan for at least some snow accumulation, followed by ice.  Sunday will find a wide variety of weather with possible 40s and rain in Salem, while Portland stays near freezing with icy weather not breaking until Sunday night.  The coast will see nothing but rain while the Gorge waits until Monday or Monday night to warm above freezing.

Portland Weekend Snow Chance - Dec. 30, 2016

By Rod Hill on 2017-01-01

Saturday Night, Sunday Snow Chance Update:  Saturday 9:45 a.m. 

PORTLAND LIKELY TO STAY MORE WET THAN WHITE, AS GROUND TEMPS WILL LIKELY STAY ABOVE FREEZING. 

Likely Saturday evening rain and snow showers and maybe all snow north near Longview.  Confidence is now strong that Portland and other low elevation areas of the Willamette Valley will stay above freezing until Sunday night.  A mix of rain and snow is expected for the Rose City as ground temps hold above 32 degrees.  The heaviest moisture will fall during the morning hours, light showers will be possible into Sunday night.  

Elevations near and above 300 feet and north of Vancouver, will have the best chance of seeing freezing temps with a dusting to 2" of snow on the ground.  High hills may see up to 3" but the moisture looks to be limited and temps at 1,000' may in spots hold just above 32 degrees.  Morning west winds may also act to keep some high elevation spots above 32 degrees.  Colder east winds will develop during the afternoon as moisture becomes light and scattered. 

Saturday night and Sunday travel to the coast:  2-4" of snow over the Coast Range with possible dustings at the beach!  Monday flurries will be possible. 

Saturday night and Sunday Gorge travel:  1-3" of possible snow, including Hood River.

Saturday night and Sunday Cascades:  6-10" of snow, amounts could be higher, but total moisture seems to be limited.  Snow levels will be below 500 feet.

Sunday Morning Snow Update - Jan 1, 2017

By Rod Hill on 2017-01-01

Live cameras this morning show 2-3" of snow on the ground over the Coast Range near 500 feet.  Cascade foothill cameras show 1-3" on the ground from near 1,000 feet.  Cascade passes as of 9:30 this Sunday morning show 4-6" of snow with higher amounts up high. The hills of the Willamette Valley in wine country show a dusting to 1" of fresh snow.  Other snow reports include:  Amboy, Rainier and Kalama with 4-5" on the ground, Woodland Hills at 1,000' 6" of snow, Scappoose hills, 2-3" of snow and Skyline in the West Hills at 750', 3" of new snow!

Metro areas from Longview to Portland to Salem will hold in the mid to upper 30s Sunday afternoon with a mix of rain and snow showers in the air.  Afternoon moisture amounts will be light.  The city center of Portland may see a light dusting of snow in the grass at times, otherwise wet conditions, not white are expected. 

Temperatures will drop into the low to mid 20s Sunday night into Monday morning with snow flurries expected, but no accumulation.  Keep an eye on next weekend.  The temperature forecast is uncertain as heavy Pacific moisture is tracking to push inland.  Will it be heavy rain or heavy snow and ice?  Keep updated.

Wednesday PM Ice and Snow Threat

By Rod Hill on 2016-12-14

POSSIBLE WINTER WEATHER UPDATE:  Wednesday 5:35 am  (Dec. 14, 2016)

A low pressure center will track over Klamath Falls to Burns to Boise, Wednesday afternoon through Thursday morning.  The track will stay well south of the Portland and Salem metro areas.  A big snow storm is not expected, however hours of light snow Wednesday afternoon and evening will be enough to cover roadways and make travel difficult through Thursday morning. 

This storm will give our region a "glancing" blow.  Total accumulation may be as little as 1 - 3" on the ground over the Portland area. Lighter amounts will be west and north of Portland, while heavier amounts will be south and east of the Rose City.  Salem will see 2-4" of snow, Cascade foothill communities such as Silverton could see 4" or more of snow.  To the north, Longview will see flurries at most.  The Coast Range may see only 2-3" of snow and the Cascades a good 6" or more.

Portland Winter Storm Likely Thursday

By Rod Hill on 2016-12-07

WINTER STORM CONDITIONS LIKELY THURSDAY FOR PORTLAND BUT SALEM MAY SEE ONLY RAIN

Gusty east winds blowing out of the gorge will pick up Wednesday afternoon and blow through the day Thursday.  Wind gusts near the gorge may reach 50 mph.  The east wind will play a role in setting up cold temperatures as Pacific moisture arrives Thursday morning.

Forecast models now show possible dry weather over Portland early Thursday into mid or late morning.  Light snow or flurries will be possible before heavier moisture arrives before the noon hour.  Sleet or freezing rain will be likely near the gorge, over Portland and north into Vancouver much of the afternoon.  Ice accumulations of .20" will be possible.  Areas near Wilsonville and south to Salem may end up seeing mostly a rainy day.  However, scattered cold pockets, especially near the mountains may see snow accumulation up to 4" and or an icy mix.  All areas except the mouth of the gorge will change to rain during the evening hours.  I am not sure when Troutdale and other east county locations make the change over to all rain. 

At this point, the most certain points of Thursday's forecast is the expected rain over Salem and a period of icy weather over Portland or at least near the gorge.  Please watch temperatures and updates as the potential winter storm develops.
