Thunder and Downpours For Some Wednesday P.M.

Interesting development in the past two runs of mesoscale models, showing quite a bit of thunderstorm action popping up over the Cascades and Eastern Oregon tomorrow.  Then both our RPM and the WRF-GFS take the energy west over Western Oregon.  Seems increasingly likely that SOMEONE west of the Cascades, probably south of the Portland metro area, will get a soaking within the next 24 hours.  Take a look at the rain forecast from the RPM:

RPM_12KM_Precip_NWOR

and the WRF:

wrf_Rain_Wed_PM

Note they both keep action south of the metro area.

One sure sign that something exciting is going to happen tomorrow afternoon/evening?  I don’t work tomorrow.  I won’t be  west of the Cascades, and won’t even have cell phone coverage from around 1pm-9pm.  I’m going on the yearly recreation trip with my kid’s school.  It’s at the old Rajneeshpuram (now Washington Family Ranch) which is way out in the middle of nowhere.

If thunderstorms do develop west of the Cascades, the First Live Local weather team will be Tweeting and posting updates to Twitter and Facebook.  Both are FOX12WEATHER.

    That’s what we call a bust. Forecasts this time of year usually are. Nobody got soaked and the models were totally wrong even though it was short term.

  2. High Desert Mat says:

    Nonstop thunder and lightning ⚡ for the last hour and a half. Rattling the house.

  3. WEATHERDAN says:

    Cloudy but still 70 in Salem this afternoon. except for a couple of spritzes of rain Salem has been dry all week. Decent holiday weekend weather coming up as well. Sure better than some years. Peace.
