• Sailing is all about the Weather.

    Big into the exploration of Atlantic Hurricanes since Katrina came uninvited into his world, James (Jim) Gurley (JamesG161) has followed every Tropical Storm birthed in Atlantic, Gulf and Caribbean waters since. Being a boater, he knows that we often need more time to prepare than we get from the TV weather folk. Jim relies on the science of storm development to share early warning info with friends and fellow boaters.

    Early in 2018, Jim and John Shepard, (JSSailem) started to chat about the weather data available. John asked Jim to help forecast Pacific NW storms, and this morphed into discussions on weather forecasting.

    For John, sailing in the PNW is sometimes hit and miss. One day is ugly, then a string of beautiful days but no wind, followed by a series of blue-sky days and 12 knot breezes. Being ready for those great sailing days means you need to look to the Pacific Ocean and what is brewing. John has been into Pacific NW Weather since the 1970’s when his first PNW November storm hit bringing more than 40 days and 40 nights of continual rain.

    Together we want to share information, new APPs, safety, and thoughts about letting the weather help you. Identify some of the resources for sailors and help prepare you for your next sailboat outing.

    It is far better to go out on the water knowing what to expect in weather terms, than to be out on the water and see dark ominous clouds suddenly appear, unprepared.

It is shaping up to be a series of hot - cool Extremely HOT days as July comes to an end and August begins. As I was reviewing the Western Pacific Storms, Rufus sent me his forecast for the PacificNW coast from BC to Oregon.

Here are his insights. May need a cool beverage to review this 3 week look at the temps.

Monday July 28

Several hot cycles are charting over the next 20 days, with “breaks” in between. Keep the ice handy.
The upper-level High pressure ‘dome’ currently setting over the SE United States - resulting in triple-digit temps - is charting to shift to the western US in several days. Be ready for triple-digit temps, esp in western OR & SW WA.
  • This week, July 28-Aug 1: Turning hot Tue & Wed; temps in the 90s in western OR; high 80s around the Puget Sound. Cooler in Friday. Thunderstorms possible along the OR Cascades, with a very slight chance for a storm cell to drift over western valleys on Thu.
  • Aug 2,3 weekend: Pleasant summer temps in the 80s, as an onshore flow taps down summer heat.
  • Week of Aug 4-8: Slowly heating up during the week, with temps rising into the 90s by the end of the week. Note that southern BC and the far north corner of WA may experience some cloudiness as weak system slides to the east of the BC Coastal Mountains.
  • Weekend of Aug 9,10: Heat build-up continues, with upper 90s the rule in western OR and east side. Heating up to the north, as well. Possible for a triple-digit reading in Medford and maybe as far north as Eugene.
  • Week of Aug 11-15: Triple-digit temps in many western locations, including Portland area. The extreme heat could last 3-4 days. Latest model runs are tapping down the threat for 103-106 degrees, but that has been on the charts, at times. Either way, this could shape up to be miserable weather. Southern BC will also be hot.
We will monitor this situation closely, per usual, and keep Patrons posted as to what could become a major summer weather event.
