Well, let me ask you this: Let聮s say you聮re confronted with a 聯sudden weather change.” What exactly are you going to do? Run for the car? Pull out an umbrella? I mean, weather happens. Better to be prepared for it than expect to dodge it.
Suunto Core Watch

That said, I聮m more than a little bit of a weather junkie, so there certainly are some things you can do. I do like the weather radio bit, for instance. Midland makes a pretty good one called the 74-250C ($35; midlandradio.com), which receives all the NOAA weather channels. I won聮t guarantee reception everywhere, but you should do OK in most places.
I also think it reasonable to have a pocket altimeter. Any garden-variety altimeter watch offers that feature, because, after all, an altimeter is simply a barometer with different calibration. Brunton聮s Nomad V2 Pro ($139; brunton.com) is accurate and compact, although not wristwatch-size. It also has a compass feature, so is a useful gadget. Suunto聮s Core I find rather pricey at $250 (suunto.com), but it聮s a nice instrument and very accurate. But an altimeter/barometer doesn聮t 聯forecast” the weather any more than a watch forecasts the future. They simply detect changes in barometric pressure, which in turn may indicate changes in the weather.
But there are lots of other resources. You have a Washington state address so maybe you do a lot of trips around here. The regional National Weather Service web site (wrh.noaa.gov/sew/) offers detailed forecasters聮 short- and long-term discussions, giving you a heads-up on weather that聮s a week out. This is a tough area in which to forecast, but I聮ve found their forecasts for 48 hours and less to be extremely accurate. Those from 48 to 96 hours are reasonably accurate; anything from 96 hours out is a decent guess but subject to change. The forecasters would agree with this assessment, I聮m sure. So right away you can leave the house with a good snapshot of what聮s going to happen. The weather radio may give you more updates.
Then, I always recommend learning to read the weather yourself. Really, 聯sudden” weather changes aren聮t that sudden. There typically are lots of atmospheric tips that something is in the works. Get a copy of KING-TV weather guy Jeff Renner聮s excellent book, Mountain Weather: Backcountry Forecasting and Weather Safety For Hikers, Campers, Climbers, Skiers, and Snowboarders. It聮s $15 (), and with a few reads you聮ll be divining the sky like a seasoned pro.
