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.

Spring so far? About as normal as it gets! The next week or so look pretty close to normal; no extremes. Rainfall will be near average and temperatures close as well

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.

Winter is over in the lowlands west of the Cascades Winter is over in the lowlands west of the Cascades, but what does that mean?

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

Windy! A sort of "Baby Bomb Cyclone" (yes, I made that up) arrives on PACNW coastline overnight. Details on timing and strength in my weather blog post this morning www.kptv.com/2025/02/24/f...

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

Widespread snow or freezing rain later this week I was hoping that we could avoid a significant snow/ice event this winter, but now it appears something significant weatherwise is looming for Thursday and Friday

Quick explanation plus a "best and worst case scenario" later this week in my weather blog this evening. Sorry about the poor timing florists and bakeries! www.kptv.com/2025/02/10/w...

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! β€œSleddable” snow unlikely rest of this week 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

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

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...

New weather podcast just dropped. Of course it's all about the upcoming snow setup, plus an introduction to our newest team member, meteorologist Payton Major. She grew up right here in Beaverton! Plus, Camila went on quite a rant about those weather apps. Video here: www.kptv.com/podcasts/wea...

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 😲

Snowfall totals map pf rare and historical snowfall event across the South from January 20th through the 22nd, 2025.

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.

25Β° at PDX this morning, edged out Sunday's 26Β° 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

Gloomy again today under the inversion/clouds/fog in western valleys, EXCEPT a small area downtown Portland eastward to the mouth of the Columbia River Gorge (some dry east wind). 3 dots are Hillsboro, PDX, & Troutdale. Drove with sunglasses first 1/2 of commute, then it got dark... Sunnier tomorrow

A historic damaging wind event in southern California this evening with at least two fires raging. The gusts 70-80+ in some flatland locations (Burbank Airport) are particularly amazing
