Today and tonight…High pressure will continue to dominate at the surface while the cold front to the east slides father to the east. Northwest flow aloft will continue today but will slowly begin to flatten out overnight but more so on Saturday. This will keep things on the cool and dry side for the most part today however we will begin to moderate late this afternoon and tonight as LL winds back around to the southwest and south. This will begin to increase the surface moisture over the area leading to lows tomorrow morning running about 10-14 degrees warmer than this morning’s lows.
This weekend we will continue to see temps moderate with both lows and highs running above normal. There is still the possibility of a few showers early Saturday. A weak impulse will drop down through the area just before the mid-level flow goes zonal early Saturday. There is still a question of how much moisture will be available to squeeze out but will add slight chance of showers across the northern half of the area for Saturday. Rain chances will begin to slowly increase overnight Sunday as increasing lift and moisture over the area leads to showers and possibly a few thunderstorms but the bulk of the rain will likely remain just north of the area.
Next week looks active and wet. With that disturbance closing off just west of the Baja region it will be rather slow to lift out. This will keep the area under southwest flow with deep pacific moisture in the mid and upper levels streaming in while Gulf moisture will continue to pump into the area. The main issue will be the development of a weak frontal boundary Monday that will sag south towards the region Tuesday but will stall before reaching the coast. This along with the abundant moisture and broad lift aloft will lead to scattered to numerous showers and embedded thunderstorms on and off through the entire week. By the end of the work week we could see rainfall totals range from 1.5 to 5 inches with isolated higher amounts; the most likely area to see these higher totals will be along and north of the 10/12 corridor.
