I am again posting an animation of the water vapor satellite picture. This is because the low pressure area is very weak and the water vapor shows it better. To answer the question from the comments of the last blog. This water vapor image is from the upper levels of the atmosphere and focuses on moisture at that level. Approximately 30000 feet. This image is from this morning to get an updated image click the link above.
A weak upper level low pressure area is just off the coast and will move across Northern California today. The low will trigger thunderstorms over the foothills and mountains with an isolated thunderstorm possible in the north end of the valley. Temperatures today will be slightly above normal.
Tuesday will be sunny with above normal temperatures and light winds. Wednesday there will be some afternoon cumulus and isolated thunderstorms over the higher elevations north and east of the valley. Temperatures Tuesday and Wednesday will be about 5 degrees above normal.
The map below shows the weather pattern we will be under Thursday through the weekend. Strong high pressure will be over the western U.S. with a low pressure area moving into Canada. Inland areas will have clear skies with temperatures 3 to 5 degrees above normal. Winds will light nights and mornings increasing in the afternoon from the south and southwest.
