The first cleared night of very cold air advection into the San Joaquin Valley. High N-S pressure gradients maintained wind mixing for the Central and West Side of the Valley moderating morning minimum temps following high temps Thursday the 10th only in the upper 40s to around 50. Min Temps ranged from 26-32 with the lowest readings in the center of the Valley in the mid to upper 20s...South Valley temps were in the upper 20s to 32F. |

Another night in the current "cold" episode. A weak vorticity max in the NNW-SSE flow aloft generated a low cloud field that resulted in some terrain-induced precipitation...snow flakes observed on the South San Joaquin Valley floor from Tipton to Porterville...and around the upwind slopes of the S.Sierra and Tehachapi Mtns. The cloud cover minimized radiational cooling despite Friday afternoon max temps only around 50 degs F. Dew points remaining in the 20s and overnight min temps reflecting the higher dew points. Temps initially dropped to as low as 32F as early as 1800 PST but then bounced up with the arrival of clouds...staying in the upper 20s to mid 30s for much of the night and dropping only to the upper 20s with a few colder areas spiking downward to the mid 20s at dawn. |

Coldest night thus far in the episode as winds went to calm, clear skies all night, and ridging aloft providing weak northeast flow over the S.Sierra Nevada. Durations less than 32F began 1800-2000PST and lasted through 0900PST. Durations 27F or lower from 0000 to 0800PST. Min Temps in the citrus belt 23-27F. |

What started as a potential for the coldest night of the current cold episode for the Central and South San Joaquin Valley moderated in the very early morning hours. Monday afternoon Max Temps were only in the upper 40s with residual, trapped air in the S.J.Valley Air Basin. Dewpoints were in the low to mid 20s with a rogue 19F at Lemoore at sunset. 24-Hr Change indicated temps similar to Sunday Afternoon but dewpoints were 1-5F lower. 32F was reached by 1900PST in coldest locations and 27F as early as 2200PST. NE wind flow aloft was the likely culprit for initially lowering dewpoints but around 0300PST flow reached sufficient strength to effectively stop and/or slow temp falls. Representative minimums around the S.J.Valley were 27-32F with a few coldest locations down to 24-26F...primarily the center and west side of the Valley. |

While protection measure still needed, strong inversions over area citrus provided the ability to minimize any damage to crops to only unprotected areas. Minimum temperatures solidly ranging from 25-29F.

The current cold episode continues with a very strong mid-winter persistent ridge over the area.

Patchy dense morning fog developed this morning in the Central and South Valley. |

Following daytime highs in the 60s in the Central S.J.Valley and the low to mid 70s in the South Valley, overnight minimums were generally in the mid 30s to lower 40s. A couple of citrus locations managed to drop to 32F but only low-lying CIMIS stations showed sub-freezing minimums around 31F. Last of the "cold episode" as moderating cloud cover brought minimums all into the 40s for the morning of the 24th. |

A moist Westerly flow with the primary baroclinic zone north of the area brought overnight very light rain/mist
to the area. Light winds with the dissipating frontal band has allowed low-level moisture to reside the Valley thereby lowering visibilities with residual low ceilings/fog. |
