7 Day Cloud Forecast For The Solar Eclipse

We are still 7 days out, but all eyes are on the CLOUD FORECAST for next Monday! I've been pretty worried about the pattern lately, but I'm starting to get a little more optimistic. Typically, when a ridge of high pressure aloft moves close to us, we get hot and sunny. Heading into next week, we have an upper-level high pressure SW of us... nudging in our direction. That's the good news, but the bad news is if we are stuck on the perimeter of the ridge. That will leave us in a path of storm complexes or Mesoscale Convective Systems (MCS). Here's the GFS model for next Monday:
My hope is that the ridge builds in enough to keep the storms WELL to our north. The latest data shows that could happen:
Even if this happens, some HIGH clouds may linger into the early afternoon. If this occurred, we may still see the eclipse through the high, then clouds (optimism). Here's a look at the Euro and GFS cloud cover at eclipse time. The upper-left shows total cloud cover. The upper-right shows medium cloud cover. The lower-left shows low level cloud cover. The lower-right shows high clouds:

Here's the GFS:
 Here's the Euro model:

We are still 7 days out! We will update you every day as we get closer to the eclipse.
