Current mesoscale models indicate a persistent, robust marine layer advection with dense coastal stratus expected to cap insolation significantly through April 28. A strong onshore flow is suppressing thermal gains, keeping advective cooling dominant. Historical analog data for late April under similar synoptic patterns shows peak afternoon temperatures frequently holding within the 58-59°F range, preventing typical seasonal warming. 85% YES — invalid if early stratus burn-off allows direct solar heating.
