Summer 2022 is one that Pacific Northwest seasonal forecasters would like to have back. On the heels of a very wet and cool spring, and with La Nina conditions persisting in the Tropical Pacific, forecasters favored near or slightly below-average temperatures this summer. Instead, we’ve had well-above-average temperatures ever since late June, with an astonishing […]
6:30 pm EDT Most wildfire starts during Pacific Northwest summers occur on just a couple of days, when large dry lightning outbreaks impact the region. The most extreme dry lightning outbreaks can cause hundreds of starts over a period of hours. A moderate dry lightning outbreak occurred on August 9th and 10th, when a deep […]
I’m writing this blog from a hotel in Greenwich Village in New York City! I flew in here on Wednesday afternoon to spend a few days in the city before going to the Hamptons Jazz Festival on Long Island, a summer-long jazz festival hosting some of the biggest names in jazz.

The flooding forced the evacuation of 10,000 citizens and the National Guard rescued 87 […]
We are finally starting to see some summer-like weather over the Pacific Northwest. I went for a nice bike ride on Sunday down to West Point in Discovery Park, and the weather was absolutely perfect, with highs touching 70 degrees at Sea-Tac and a mix of clouds and sun. Tons of riders were out on the Burke-Gilman […]
La Ninas typically feature cool and wet springs, and the 2021-2022 La Nina has had that in spades. According to Chief Fox12 Meteorologist Mark Nelsen, Portland just experienced its wettest April on record, the coolest April since 2011, and, as denizens of the Portland metropolitan area know all too well, had a very rare April […]
