Portland Weather Forecast

Today's Forecast

Thursday, May 23rd 5:30pm

Record breaking rain on Wednesday. The Rose City picked up 1.19" and more is on the way.

For the month of May we now have 2.55" of rain that's over 3/4 of an inch above normal. Another round of rain will sweep across the region tonight. An unseasonably cold upper level low remains planted over The Pacific Northwest.

The low will drift to the east on Friday taking the heaviest precipitation with it. Temperatures will begin to warm and we should even see a few sun breaks. Heading into the Memorial Day Weekend expect continued partly to mostly cloudy skies. Temperatures will reach the middle to upper 60s. Not great but at least better than the last few days.

Intense thunderstorm upstages cruise ship entertainment (Photo Gallery)

By Scott Sistek Published: May 23, 2013 at 9:55 AM PDT

It's not often entertainment on board a cruise ship can be upstaged but on this particular night, Mother Nature gave it a shot.

Make that, several shots...

I took this video as the Disney Fantasy sailed into the Gulf of Mexico on May 1 just hours after it left a very hot and muggy Cozumel, Mexico.

(How hot? I went back and checked when I got home and it was 86 degrees with a 73 degree dew point that evening. Or as this Seattleite said: About 3 degrees cooler than molten lava. Though I'm sure many of the Florida residents on the ship probably thought it was a bit chilly.)

Weather Blog Brrr! Portland coldest major city in the nation Wednesday

Does it feel a bit like January out there Wednesday? Your skin did not deceive you.

A cold system from the Gulf of Alaska had settled into the Pacific Northwest, bringing not only a steady winter-like rain but has kept temperatures stuck in the 40s(!) through much of the day.

In fact, at 1 p.m., Portland was hovering at 46 degrees -- about the average high for mid-January.

The Rose City would finish the day with a high of 50 degrees --- the second coldest May day on record -- for any date! It shattered the daily record for coldest high temperature on May 22 which had been a "balmy" 55.

It was so chilly in the Northwest that Portland was given the "honor" as the coldest major city in the United States! (Even colder than Seattle (52) and Anchorage (54), although if you add in smaller cities, tied with Spokane, Washington, also at 50.)

Weather Blog How tornado victims got 36 minutes of precious warning time (Photo Gallery)

Thirty-six minutes.

That might not seem very long -- roughly about the time it takes to wade through your hourly drama if you blaze through commercials. But compared to a few decades ago, 36 minutes of time might have saved countless lives during the devastating tornado that struck Moore, Oklahoma on Monday.

Years ago, the residents of Moore would have likely had no idea the tornado was coming until the twister was sighted, giving people barely a few minutes' notice. But thanks to advancements in technology, tornadoes rarely sneak up on anyone anymore.

In fact, forecasters as early as Wednesday began sounding the alarm for a potential severe weather breakout on Sunday and Monday. And, on Friday, the forecasts became more specific. On Monday, a Tornado Watch, which indicates conditions are right for tornadic development, was issued at 1:10 p.m. for much of Oklahoma, including the greater Oklahoma City area.

Weather Blog "What does ''EF-4'' mean?' and other tornado questions answered

By Scott Sistek Published: May 20, 2013 at 4:10 PM PDT

With tornadoes in the news lately I figured it'd be a good time to post answers to some frequently asked questions about the powerful storms:

What does "EF-4" mean?

WIth the devastating tornado in Moore, Oklahoma, you'll be hearing a lot of about "EF" ratings -- that's from the Enhanced Fujita Scale that rates tornadoes on a scale of 0 to 5, 5 being the strongest.

The Moore tornado was given a preliminary rating of EF-4 ("Devastating") with estimated tornadic wind speeds of up to 200 mph, although many are thinking that rating could be increased to an EF-5 ("Incredible") once more damage assessment is done.

Sadly, it's not the first time Moore has had to deal with such a catastrophic storm. On May 3, 1999, Moore was struck by an EF-5 tornado which recorded the strongest wind speed ever registered near Earth's surface. this map provided by the National Weather Service in Norman, Oklahoma shows just how close the two tracks were.
