FORECAST:

The upper ridge will maintain until the middle of next week in a Rex Block pattern. The flow for today will be Northwesterly aloft. We will need a strong off shore flow or some precipitation to help with the smoke issue. Will update the forecast later in the weekend. Update- Northerly flow aloft will continue into the middle of the week according to the latest models. The upper ridge will strengthen and move farther North Monday and Tuesday. We may see some stronger offshore flow by Wednesday. An upper trough is forecasted for Friday/Saturday which will hopefully clear out most of the smoke, lets keep our fingers crossed.

    High pressure again for today.

    High may weaken a bit later today with possibly some slightly cooler temps.

    Rex Block Friday thru Monday.
