The ridge of high pressure responsible for the heat the last few days is beginning to break down allowing high clouds to roll in helping to keep our temperatures down a bit. Highs on Thursday were in the low to even upper 90s depending on where you are and it will still be on the warm side on Friday with highs right around 90 degrees give or take.

The cooling trend will continue into the weekend only topping out in the mid 80s on Saturday and upper 70s on Sunday.  The reason for the cooler weather is all thanks to an area of low pressure over the Eastern Pacific breaking away at the ridge.  The low will eventually move through the Northstate and give us a chance for isolated showers and thunderstorms on Monday in the valley and mountains.  We may even see some isolated activity in the northern mountains as early as Saturday and Sunday but the best chance will be on Monday.

The storm will be to our east by Tuesday giving the Sierra a continued chance for isolated thunderstorms but the rest of us should be dry with gusty north winds unfortunately drying things out and increasing the fire danger.  We should return to the mid 80s by the middle of next week as high pressure starts to rebuild.
