Possible fog for July 4th fireworks

by Christina Favuzzi, KSBY Forecaster

The high pressure ridge that brought those muggy conditions this week is moving out of our area. Now an approaching low pressure system will lower the marine layer Friday night, bringing cooler conditions for the coast and valleys this weekend.

Paso Robles is the hottest spot on the Central Coast this weekend with highs in the low 90s. San Luis Obispo will be in the mid 70s and beaches will be in the 60s. Santa Maria and Santa Barbara will have highs in the low 70s.

Fourth of July fireworks conditions are a bit of a toss-up. The marine layer shelf will hover between 500 and 800 feet which may interfere with fireworks viewing.

Expect average temperatures through next week with overnight and morning cloud cover that will clear in the afternoon hours.

Muggy air moves out and coastal clouds move back in

by Dave Hovde, KSBY Meteorologist

The upper level flow which has been pumping sub-tropical moisture muggy air into the Central Coast is finally turning more W-SW which will eliminate the high clouds but also help to foster more low clouds near the surface.

The onshore flow will be dominant thru the holiday which means night and morning clouds at the beaches with some places only clearing partially. This will produce a cooling trend at the beaches and near coastal valleys but inland temps will still hover in the 90s (just getting less muggy).

The coastal clouds could have an impact on fireworks displays, typically you’d like the deck above 500ft so fireworks go off underneath any clouds but at this point it simply looks very close to that level.

We’ll see a trough off the coast with a weaker ridge to the east much of next week setting the stage for mild conditions more typical of early summer with no threat of thunderstorms. Night and morning clouds near the coast with near average temperatures.

Shower chances diminishing as 4th weekend nears

by Dave Hovde, KSBY Meteorologist

Plenty of subtropical mid to high-level clouds pushed over the area today. We saw sprinkles and a few rain showers and there were reports of thunder especially in the NE portion of the area earlier today. This monsoon moisture is actually decreasing the amount of coastal low clouds and fog along the immediate shoreline.

The high pressure ridge responsible for the hot and muggy weather weakens Thursday for generally cooler weather heading into the July 4 weekend.

The Fourth of July will see marine low clouds in the night and morning hours with partial afternoon clearing at beaches and partly cloudy skies elsewhere with temperatures closer to seasonal averages.

Weather changes for holiday weekend

by Christina Favuzzi 

Warm, muggy air will move over our area tomorrow and throughout the week. That’s due to a high pressure system hovering over the great basin.

Expect triple digit heat in areas of the interior valleys of San Luis Obispo County Wednesday. Humid, unstable air from the southeast will bring a slight chance of rain and thunderstorms Wednesday.

Look for cooler temperatures later in the week and into the July 4th weekend. Possible fog for fireworks but pleasant temperatures in the mid-70s for the majority of the Central Coast for the holiday. Weekend temperatures for Paso Robles will top out in the low-90s but much cooler temperatures in Santa Maria with highs of in the high-60s.

Hot weather inland continues with rain chance

by Dave Hovde, KSBY Meteorologist

High pressure is getting stronger Wednesday, while muggy sub-tropical air continues over the Central Coast. It’ll be another hot day inland with triple digit highs for the interior valleys and much cooler in the coastal valleys and the beaches thanks to onshore winds there.

The big issue is the chance of showers, there is enough sub tropical air pumping into the area that showers and a slight chance of showers are in the forecast (generally Santa Maria and south, and a better chance inland and at higher elevations). The showers can’t be ruled out elsewhere however.

The ridge is expected to finally weaken by Friday for generally cooler weather for the holiday weekend.

Fourth of July marine low clouds are expected to roll in for the annual fight between the fireworks and the clouds.

Sub-tropical air continues to push in and rain is possible again

by Dave Hovde, KSBY Meteorologist

Hot weather returned to inland areas today and Tuesday looks even warmer. Paso Robles hit 105 on Monday and more of that flavor is on the way until later this week, in fact humidity looks to be on the increase as well. Some of the lows this week in the valleys will be in the 60s.

Closer to the ocean, night and morning marine low clouds and afternoon onshore winds will keep the beaches and coastal valleys from getting very hot.

The upper level ridge is so amplified that we are in the return flow area, and southerly flow will pull instability into the area and models are showing some Wednesday and Thursday potential for showers and thunderstorms.

The ridge breaks down as the week ends for cooler weather and marine low clouds for the 4th near the coast during the night and morning hours.
