ECMWF Weekly Maps

The usual, 4 maps of the upcoming 4 weeks off last night’s 00z ECMWF.  Trend remains similar to what we saw from Sunday night’s runs:  Cool troughing through the next 2 weeks, then more ridging over most of North America with the West Coast on the western edge of that…I interpret that as “warmer rainy weather”.  Probably no “near snow” setups beyond mid March if this is correct.

    A inch of snow works for me!

    A very cold airmass will remain parked over the area as a secondary shortwave moves through Sunday. Showers will be enhanced late Sunday
    morning through and Sunday evening with this disturbance. Snow levels will be especially low…with possibly sticking snow in the
    Willamette Valley. In areas where the snow will stick…snow amounts
    will be low…less than an inch…with breaks between the snow
    showers.

  2. A bright sunny morning with a low of 29°.

    Cold weather and snow showers works for me!

    Generally…expect cold
    air and snow showers in lower elevations..

    Really like this thought!

    Another thought…here’s the 12z 4km WRF-GFS snowfall forecast from 4pm Saturday to 4pm Sunday. When I start seeing “fingers” of snow moving out into the valley hills as I see here, that’s when we get very close to sticking snow in the lowest elevations.

    Let’s shoot for a late March heat wave, as in 3-5 days in the mid 70s!!!
