Lightning and Hail Today; But Summer Weather Ahead

2pm Wednesday…

Scappoose and northern Sauvie Island just got pounded with 11 lightning strikes the past hour as a strong thunderstorm moved through.  Probably a bunch of hail too!


As expected, a real active midday today as the chilly upper level trough is moving overhead.  We’re actually on the backside of it this afternoon so theoretically the action should die down.  But we’re also headed into the peak heating of the day, so through 5-6pm just about anyone could sail hail or thunder.  As of 2pm there haven’t been any other lightning strikes detected by the system we use (WSI).

Enjoy the rain and hope your garden gets a good soaking because I see little or no rain in the next 7-10 days.  Here is the ECMWF meteogram showing the mild and dry weather after today, although I think it’s a little on the warm side for parts of next week.

    Wow! 0 – 100, & back to 0 all in about 2 minutes time!!

  2. Had nearly a dozen lightning strikes out here near BG. One was very close, I didn’t even have time to start recording.

    4.09″/hour peak rainfall rate. I can’t recall one that high ever, or in a very long time.

    Isn’t it a bit stretchy to talk about the upcoming “summer weather” when the warmest day on the 7-day is 78 degrees? Maybe if you qualified it by saying “early summer weather” it would be more reasonable…

  4. Only made it to 59 at my house. Peak wind of 22 mph with 0.38″ of rain so far.

    Peak rainfall rate was 2.73″/hour at 9 AM.

    Low windchill was 43 at noon. Brrrr

    Hey Mark, can you talk a little bit about why the short-term forecasting has had some difficulty predicting precip & temps with this system? I imagine it has something to do with the nature of the trough, but I’m curious because the ensembles that make up (Dark Sky) have been all over the place in the last 48 hours or so. Thanks!

    I think you could say that Stray had a KICK to it! Hahaah!

    At least I don’t have to water my tomatoes today, raining quite hard right now.

    Just heard a thunderclap here in Tigard. Some big cells nearby…

    Let’s see if this works. Intoxicated North Dakotans up close with a tornado. Warning – foul language, but I suppose that’s redundant with intoxicated North Dakotans.
