Weekend Cooling Trend, Memorial Day Should be Sunny and 75

Weakening high pressure and increasing onshore flow will bring a cooling trend to Pasadena through the weekend, National Weather Service forecasters predict. Memorial Day is expected to be sunny and 75.

A persistent marine layer will expand into the San Gabriel Valley by Friday and Saturday, making for ‘May gray’ mornings that give way to sunny skies.

A warming trend is expected by next Tuesday.
