Saturday Evening Update; Left All Alone

A busy day in the weather center today!  FOX12 will be constructing a news set and weather center in the same location that we currently do news from.  We call it Studio A.  So most of the current sets were moved from into the other studio to allow a month or so for construction in here.  But the weather center was left…all by itself in this huge room.  That, and a temperature of 64 degrees in here, is making me feel isolated and cold!  The picture pretty much tells the story, suddenly our “big” weather center looks very small.  You can see where the main anchor desk was on the white, unpainted floor area.  Also notice the entire colored, 12 foot high backdrop is gone behind us:


We’ll be moved onto tables for a month or so and then we should be into shiny new headquarters by late summer.

Weatherwise, a bit of a change in the last 48 hours.  Models are again trying to build an upper level ridge much closer to the West Coast for the upcoming week.  If so, we’ll be within 5 degrees of that 90 degree mark the entire week.  In fact it’s interesting how little marine influence we get over the upcoming week.    No low clouds even close to the Oregon coastline mean another clear and cool night tonight, then a sunny start with temps up in the lower 80s again for Sunday.  Expect warming temps on Monday.

Tuesday is an interesting day…a weak upper level trough offshore swings up along the Oregon Coast, then up to around Vancouver BC by early Wednesday morning.  This gives us 3 weather “events”.

  1. Weak offshore flow on Tuesday…a +18 or +19 with flat or easterly gradient will push us into the lower 90s for one day.
  2. Thunderstorms may break out from northern Oregon (Tuesday evening) through western Washington (overnight into Wednesday AM).  Isolated stuff, details to be ironed out later.
  3. Marine push behind the trough Tuesday night.  Although not strong, it should be enough to drop temps 6-10 degrees for Wednesday.

You can see the relatively stable pattern for Thursday-Saturday following on the 500mb anomaly map (ECMWF) next Friday morning:


It shows an upper level high over Alaska with another upper-low out over the Eastern Pacific…a “Rex Block” sort of pattern which tends to be stable.

Here are the two ensemble charts from the 12z ECMWF and 12z GFS:

tseries_850t_000-384_Portland tseries_850t_000-360_Portland

Both show above normal temps for the next week, then cooler about 8 days from now.  Other than that chance for a thundershower later Tuesday or Tuesday night, the dry spell will continue.

I’ll be on vacation for the next two weeks, so no new posts until July 29th.  Enjoy our fine summer weather!

    Thanks Mark,
    I wish I could make the event this year, but do to a massive store remodel in progress, 12 hour days and no vacation through mid August for me. You on vacation just might elevate our chances for a good thunder storm outbreak! PS, drink a couple of Steve P’s Widmers for me!!!

    When can we hear the new podcast?

  10. Greg Carstens says:

    Oh geeze Mark. You and Karl gone at the same time??? We might now be in store for more excitement then we could ever think of being able to handle…lol.

    Tuesday night into Wednesday morning. Hmm I guess I might want to try and stay up late for nocturnal thunderstorms but then again it is always fun to watch lightning flash through the window at night and listen to how long the thunder lasts.

    The NWS says it will probably be high based convection and those types of storms I have found to be less dramatic than the low based variety.

  11. Thanks Mark! I’ll be on vacation too within 10 days, albeit a short one…
