I’ve shown this image in previous posts; it’s the 6-10 day forecast 500mb heights and deviation from average. You can see the negative anomaly centered over the northern Rockies. This is quite a change from what we’ve seen the past few weeks. Basically the Western USA is going to get a sudden cool down next week. We can turn off the sprinklers and garden soaker hoses. That’s a combination of much cooler temps plus off/on rain beginning Monday or Monday night. You definitely need to enjoy the sunshine this weekend. Sunday looks perfect with strong offshore flow (gorge east wind). WRF-GFS cross section shows 35-40 kt. wind well above the surface Sunday PM.
I’ve been a bit lazy blogging the last few nights…under the weather, especially tonight. Feels like some laryngitis approaching…
