Marine Weather and Tide Forecast for Clearlake, CA

DISCUSSION

The Week Ahead
Upper level ridging continues to control the weather pattern around the area this Tuesday. Weak closed low is observed off SoCal's coast as well, and will slowly move eastward through Thursday. High temperatures will be continue to be "cooler" than the previous week, however still run around 10-20 degrees above normal, with several locations likely to meet or break previous high temperature records. As the aforementioned low moves inland, periods of breezy to gusty north to northwest winds will develop Wednesday and Thursday; strongest Thursday especially along the I-5 corridor and in the northern Sierra. Probabilities of gusts greater than 40 mph on Thursday are around 30-60% along and west of I-5. High temperatures cool Thursday with the northerly winds, but will quickly climb back to similar highs from Monday and today through the weekend.

As we move into Sunday and Monday, our upper level pattern will begin to change. A trough is forecast to deepen across the Gulf of Alaska and dig into the PacNW by Monday/into Tuesday. System is forecast to strengthen and tap into a plume of 150kg/m/s IVT, which will bring a shower chances, mainly in the northern Sacramento Valley, NE Foothills, and northern Sierra/southern Cascades and Coastal Range Monday afternoon into Tuesday. Cold air associated with the trough will also help introduce slight chances for mountain snow. Still too early to get exact details and accumulations down, however our confidence is increasing on a pattern change with cooler temperatures, beneficial rain and light snow moving back into the area next week.

As we continue to see well-above normal temperatures for this time of year, individuals should practice heat safety. Please be sure to stay hydrated and take breaks from being in the sun during the heat of the day. Always remember to use caution and wear a life jacket near area waterways.
