For the forecast, a mix of sun and cloud this morning before a weakening cold front moves onshore this afternoon for a quick burst of precipitation in a SW flow aloft. The FL should rise to around 1000 meters with the passage of the front then drop back down to near surface this evening. Monday will see unsettled conditions in the morning with clearing by the afternoon as a ridge of high pressure begins to build in the area. The ridge strengthens for Tuesday with mostly sunny skies in the morning, some cloud developing later in the day as a weak short wave trough brings cloudy skies to the area for Wednesday. The ridge rebounds for Thursday into Friday with above normal Temps.
Guesstimates: 5-10 cm by Monday morning.                                                                                                                                                                                                                                                                    

    Weakening cold front will bring overcast skies and light precipitation this afternoon.

    Clouds in the morning Monday with the ridge building for the afternoon.

High pressure builds for Tuesday.


    Weak short wave trough moves in on Wednesday from the large low to the Northwest.
