Topic: Persistent isobars over Oregon/Nevada/California border

[chman]

For months now, the Fronts map (https://www.wunderground.com/maps/) has had a dense set of isopleths over the border where California, Oregon and Nevada meet. Although today there is a High there, that is seldom the case, and wind maps (i.e. earth.nullschool.net) never show anything "interesting" there. Why is this happening? Tks.

The Rockies are a big block for weather systems
which then are forced to go around them

Shouldn’t that be reflected somehow in the New Pine Creek OR/CA weather? Shouldn’t the pattern change with time anyhow as the highs and lows throughout the region change? There was a high there yesterday and a low today but the map is the same. It doesn’t show up on https://www.atmos.illinois.edu/weather/tree/viewer.pl?launch/sfcslp or http://www.wpc.ncep.noaa.gov/sfc/satsfc.gif and doesn’t change at all when I animate the WU map.

I saw that too. When I was teaching my weather unit. It is a massive computer glitch. Hurricanes barely make that.

ah, that does look like a glitch in the (some?) models

or maybe its a big depression that has been dug into the Rockies to store North Korea's Nukes?
and that has affected the barometer reading there
