KEY MESSAGES

DISCUSSION

Visibilities have begun to drop yet again this evening just after sunset. We have another Dense Fog Advisory through 10 AM as models again are showing a 40 to 60 percent chance of 1/4 mile or less in visibility in the South Valley around Hanford and Visalia by sunrise. Once the sun rises, the visibilities will gradually improve by Friday afternoon. Other than the fog, we are seeing temperatures warm up this weekend thanks to the strengthening ridge of high pressure. There is a 45 to 90 percent chance of highs of at least 75 degrees this weekend.

The temperature roller coaster continues with highs dropping Monday and Tuesday as a shortwave trough slides through northern California. However, no precipitation is expected with this system and winds are not expected to be as gusty in the Sierra Crest or the Mojave. Another ridge slides in Wednesday bringing temperatures back up.

Before you complain, we are actually looking at a deep trough sliding in late Thursday into next Friday through next weekend that will bring in the next chance of rain. Latest CPC outlooks are highlighting a 60 to 70 percent chance of above average precipitation in both the 6-10 and 8-14 day outlooks mainly based on this system. However, the CPC also keep us under a strong signal for above average temperatures in the 6-10 day outlook which weakens to a 33-40 percent chance in the 8-14 day outlook.
