What follows record-dry April weather? A summerlike May Day
Spring has turned sharply warmer/drier compared to March and early April. Now it appears this unusual pattern continues into the first half of May.

The Ides of March? Beware of rain, but no dangerous weather
If you’ve lived here more than a year, you know our springs swing from wet to dry, cold to warm. We just had warm and mainly dry...you know what comes next!

New weather podcast episode just dropped. Spring has sprung! We cover this weekend, wet weather next week, and that sub-par "planetary parade" last week. Always lots of fun... Best to watch it here, www.kptv.com/podcasts/wea... but it should have already dropped into your favorite audio feed too.

Put a fork in it...winter is over in the lowlands west of the Cascades. But that doesn't mean the chance for a wet morning snowfall is gone (remember that spring snow in early April 2022???) New weather blog post this evening... www.kptv.com/2025/02/27/w...

First Alert for strong south wind later today and tonight
It's a First Alert Weather "afternoon and night" as strong southerly wind gusts arrive. There will be scattered power outages overnight and into the Tuesday morning commute

The big message? Confidence up that we've got a widespread snow/freezing rain event Thursday to Friday morning in the I-5 corridor, Gorge, and coastline. Have option to work from home? Plan on doing that Thursday. And yes, most schools likely close Friday. More later in a wx blog post

I interrupt your doomscrolling to bring even more doom. January 2025 was the warmest January on record globally - breaking the January record set just last year.

Sorry kids and teachers! “Sleddable” snow unlikely rest of this week in the I-5 corridor. Just finished a new weather blog post www.kptv.com/2025/02/04/s...

Because most of the showers have been over and west of the Coast Range, the best accumulations have been out there as well. This will be the case tonight and Tuesday too

New weather blog post. Big message? Kids, you need get your homework done tonight, but I'll try to get a bit more snow midweek. Plus, some of the driest parts of Oregon have a tremendous snowstorm on tap next 3 days www.kptv.com/2025/02/03/s...
Spots of snow Monday morning, but possibly more substantial snow Wednesday
Kids, get your homework done. Most of you will be headed to school the next two days, but we should at least see some flakes in the air

Working on weather blog post later this evening, but forecast hasn't changed. Cold showers (mainly snow) come/go Sunday night through Wed lower elevations. Could impact mainly morning commutes. Watching closely to see if cold arctic air pours through Gorge later next week and causes trouble 😲

Record snowfall fell across several southern states last week, including as far south as some Gulf Coast beaches.
Some locations accumulated 10.0 or more inches, recording more snow so far this winter than many locations up north, including Chicago!

Working on winter wx presentation (it's boring right now). Biggest snowstorms in Portland's history; 3-day totals. We know it used to snow a lot more 150 years ago, but look at some of those storms! Honorable mentions (not in Top 5) are January 1980, January 2017.

25° at PDX this morning, edged out Sunday's 26° for coldest of winter...so far. Not pipe-busting cold, especially with days in the 40s, in fact good for our gardens. Repeated cold nights like this really keeps them in dormancy well

...more than Portland's combined winter (0) plus last winter's total (1.6")
Pensacola, Florida now has more snow this winter than Seattle. :/

We may have called it episode 125 in the podcast, but episode 124 has dropped! We dive into the models for clues on whether a cold snap is ahead. Plus we're bringing back the term of the week AND as always-- cool viewer photos!
