North winds have decreased overnight as pressure gradients weakened in response to the upper lows continued southeastward movement. They should stay elevated at least the morning hours before becoming light this afternoon. Sunny skies and warm temperatures also continue under this weather pattern with decent dispersion expected.
*** Permissive Burn Day ***
A series of low pressure areas will keep temperatures tame and dispersion good across California this week. Some shower and thunderstorm activity will follow the lows, but as was previously stated most of the impacts will be to the higher elevations except towards the latter half of the week when clouds and showers become more widespread.
