An uncharacteristically strong storm for mid-summer is currently located in Nevada and will sweep a cold front through our area late tonight and early Friday. Temperatures will be knocked below average for tomorrow and showers will likely occur during most of the day, becoming stronger by the afternoon and early evening as any surface heating combines with cooling aloft to destabilize the atmosphere.
Showers may continue Friday night into early Saturday morning before drier air moves into the area and leads to very pleasant weekend weather with seasonably cool temperatures. Another storm will pass well to our north by Monday morning keeping these cool temperatures around for the beginning of the workweek. A ridge is then forecast to build over our area by midweek bringing hot temperatures by the July 4th holiday.
There is some model consensus with respect to monsoonal moisture from the south sneaking under the ridge by next weekend, which not coincidentally is climatologically expected around the beginning of July. If this occurs, the moisture will bring an end to the mostly dry week as showers will become stronger and more likely during the holiday weekend.
