Good morning, Central Coast!
As we kick off our Wednesday, cloud cover is looming for the commute hours. Thankfully, most spots are just under those clouds, fog is limited to a few spots, no big concerns for your morning commute.
Today temps will continue a slow warming trend as the lingering low pressure pushes east and a ridge of high pressure draws closer.
Sunshine will be the story by midday, and highs will be in the 80s in the interior valleys. Low 70s and upper 60s for our coastal valleys. Beaches will be the coolest spots with highs in the low 60s.
Thanks to a ridge of high pressure, temps are set to climb quickly Thursday and peak Friday. As we warm up with a ridge low-pressure system is expected to break from the main steering flow of the jet stream and become a cutoff low. Without that push from the jet it will stall just offshore of Baja and bring another wrinkle into the forecast.
While inland valleys will experience considerable heat and even some potential records, coastal areas will see milder conditions thanks to some morning marine layer intrusions. Gusty northerly winds are also anticipated at times.
Saturday will see temperatures trend downwards but remain well above normal, around 8 to 15 degrees above average.
The forecast for Sunday through Monday becomes more uncertain due to the nature of the cutoff low, which is favored to move west over land just south of our region. This scenario would bring southerly flow, an increase in moisture, and instability, along with a significant drop in temperatures, especially on Monday when highs are likely to be several degrees below normal. There's currently a small chance of showers or thunderstorms Saturday afternoon through early Monday, with the greatest chance of convection over the mountains.
Looking further into next week, some forecast models hint at an unseasonably cold pattern with more chances for precipitation.
Have a wonderful day, Central Coast!
