Marine Weather and Tide Forecast for Soda Springs, CA

DISCUSSION

A high amplitude upper level ridge from the Eastern Pacific extending north towards the Alaska Peninsula continues through Friday morning resulting in a warming trend. Afternoon highs will increase to 5-10 degrees above average with typical westerly winds the next few days.

On Friday afternoon, a weak upper level shortwave trough pushes through the PacNW, increasing our typical afternoon westerly winds. Gusts will be in the 20-30 mph range with a 10-50% chance of exceeding 40 mph. The main areas of concern will be north of I-80, especially mountain ridges and eastern slopes. Temps will briefly stop their gradual increase with this system.

The ridge quickly returns on Friday evening and continues a slow eastward trajectory towards the Desert Southwest. More warmer and drier air moves in leading to higher afternoon temperatures through early next week. W Nevada and NE California valleys have a high (60-90%) chance of reaching their first 90 degree days of the season on Monday and Tuesday. The NV Basin and Range lowest valleys may reach the mid-90s by Monday. Moderate HeatRisk is very likely over western NV lowest valleys on both days. Temperatures have a 50-60% chance of breaking the record highs.

By next Wednesday, the backside of the ridge starts to pull subtropical moisture from the Gulf of California towards W NV bringing back clouds and low rain and thunderstorm chances (below 10%) into the forecast. Anyway, the cloud cover will help drop temperatures back into the 80s for valley locations, but we remain 10-15 degrees above average.
