| *** Restricted Field Day***
*****Restricted Field Day due to strong morning inversions*****Allocation reductions are also in place *****Gradients have relaxed over the region today with our ridge shifting a little eastward. However record afternoon max temps could be broken again today as forecasted afternoon temps are to peak around the mid to uppers 70s...Morning and overnight inversions will continue to trap daytime pollutants which will be slow to mix out during the day.
*** Restricted Field Day***
The pattern is expected to stay dry and unseasonably mild as a large West Coast ridge dominates however by Wednesday/Thursday our ridge is expected to flatten slightly leading to some cooling leading into the weekend. Dispersion and air quality will likely deteriorate this week due to lack of mixing.
