SYNOPSIS. Dry weather and above normal afternoon temperatures can be expected over the district today and Friday. A weak cold front will move through the region late Friday night into Saturday and bring a chance of light precipitation to mainly the higher elevations from Fresno county northward. Otherwise, much of this weekend will be dry with seasonable temperatures. Monday through Wednesday will be much cooler and unsettled with a daily chance of showers and higher elevation snow.
DISCUSSION. Fine weather is on tap for the central California interior today and Friday with plenty of sunshine and springlike afternoon temperatures. High temperatures will be above 70 degrees the next two days in the San Joaquin Valley and lower foothills. Friday will be the warmer day with thermometer readings rising into the mid to upper 70s in the warmest locations. A weak cold frontal passage Saturday morning will bring an end to our very mild afternoons. High temperatures Saturday and Sunday will be much closer to normal over much of the CWA. Otherwise, this weekend will not be all that bad to get any yard work done if you haven't taken advantage of the nice weather lately to do so.
An upper level ridge of high pressure will be responsible for our pleasant weather today and Friday, even though the ridge axis shifts eastward into the Great Basin tonight. A southwest flow aloft will reside over the CWA Friday ahead of that weak Pacific cold front referenced earlier in this discussion. The upper level trough associated with this cold front will move inland Friday night and exit quickly into Nevada by midday Saturday. Moisture and dynamics are pretty limited with this system, so the precipitation it brings will be fairly light and generally confined to the higher elevations from Fresno county north when the front breezes through the CWA Saturday morning. Another short wave ridge will move rapidly in behind this system Saturday afternoon.
A southwesterly flow aloft will become reestablished over central California by Sunday ahead of yet another upper level trough over the Eastern Pacific. This will be the trough that will become a pattern changer for us, and in a very good way. How good? Well, for starters, the trough will open the door for successive upper level troughs to move through central California early next week with episodes of wet weather. Monday through next Thursday will be considerably cooler with a daily chance of showers in the lower elevations and beneficial snow in the mountains. High temperatures in the 4 to 7 day period will likely run several degrees below normal. In Fresno, for example, the probability that the high temperature on Tuesday and Wednesday will be lower than 60 degrees is 82 percent and 83 percent, respectively. The normal high in Fresno those days is 67 degrees.
Additionally, the cold air accompanying these troughs will likely bring accumulating snow down to or just below pass level as early as Tuesday morning. In fact, last night's run of the NBM indicates that there is a 95 percent probability that at least a dusting of snow will occur over the Kern county mountain passes by daybreak Tuesday. The atmosphere might also be unstable enough early next week to generate isolated afternoon thunderstorms with small hail in the San Joaquin Valley and lower foothills. Skiers should be delighted to know that these cold upper level troughs will produce generous snow in the Sierra above 6,000 feet next week. A deeper snowpack over the Sierra is just what we need to get us through the dry Summer months. All in all, it looks like we're finally going to transition to a very active weather pattern after this weekend.
