FORECAST:

The upper level ridge offshore will continue to bring dry weather in a Northerly flow aloft with the FL well above the local peaks. We can expect some high overcast this am with a few low level stratus clouds trying to push in from the South, but they may not make it into our zone, or will burn off. Likely sunnier this afternoon as the ridge slowly begins to push more onshore. Unsettled again for Sunday but the ridge will begin to strengthen with more sun than cloud. Looking like a warm sunny pattern for the next week with some convective cloud development likely.
