Dry conditions with temperatures well above normal this Monday. Cooling trend starting on Tuesday with below seasonal conditions by Thursday. 2. The next storm arrives on Wednesday with significant precipitation amounts from an Atmospheric River on Thursday and Friday. && .DISCUSSION... A high pressure ridge over now sits over the West Coast as much of the San Joaquin Valley reaches the 80 degree mark. While the southern portions of Central California favors 80 degree temperatures, the north valley will join the group as peak heating occurs this Monday. Afterward, slow cooling will start with high temperatures falling below seasonal normal values (upper 60s) by Friday. Probability of Exceedance of reaching 70 degrees has values below 5 percent starting on Friday and continues that trend through early next week. The return of wet weather will be of higher concern as a winter-like storm pushes through Central California later this week. Ensemble moisture analysis continues to show a change to wet weather starting on Wednesday(Nov 12th) afternoon with the bulk of the storm expected by Thursday Morning. Ensemble analysis has shown minimal deviation from the solution of introducing unsettled conditions on Wednesday and having the heaviest precipitation cross Central California on Thursday. Probability of Precipitation (PoP) of receiving a tenth of an inch in 6 hours starts out below 10 percent on Wednesday and increases to around 60 percent by Thursday morning. PoP of exceeding one half of an inch reaches to 80-90 percent Thursday afternoon with PoP of exceeding a one inch of rain range between 40 to 70 percent for area in the foothills and Sierra Nevada. The Valley only show values in the lower to mid teen (percentages). While ensemble moisture analysis is showing some uncertainty of the magnitude and strike zone of a moderate Atmospheric River, models do suggest that Central California will receive a significant portion of that moisture. Snow levels show less ensemble model uncertainty as confidence is high that snow levels will start above 8000 feet at the start of the storm and drop to around 6000 feet by early Friday Morning. While snow levels and overall temperatures see a marked decrease, precipitation from the Atmospheric River will see a decreasing trend as amounts taper-off. Ensemble show linger showers extending into Saturday with conditions drying out on Sunday as a ridge of high pressure returns to the area. && .AVIATION...
