    As of 07:00 Hrs this am we have some thin high cirrus cloud and unlimited visibility.

For the forecast, the upper level ridge will bring dry and warmer weather today in a Northwest flow aloft. The FL should rise to around 1800 meters in the afternoon and the flow becoming Southeasterly.  We will likely see some cirrus cloud spin off from an upper level trough moving into our zone by Saturday morning, so some thin high cloud in the mix for today. Saturday looks to be overcast with the FL possibly reaching 2000 meters with some spotty precipitation. A wetter front moves in for Sunday with light rain in the forecast and the FL topping out at around 1900 meters. A cooler upper level low will arrive for Monday into Tuesday with unsettled weather and the FL dropping to around 1600 meters. Enjoy today before some wet warm weather moves in.

    Sunny with cirrus clouds for today, a weak weather system approaching the coast for tomorrow.

    High pressure will begin to move East today.

    Warm air mass for Saturday with light precipitation in a Southerly flow.

    Cooler wet weather forecasted for Sunday, the upper level low will move through by Monday.

    Unsettled for Monday with an upper level low passing through.
