DISCUSSION
A warming trend takes place this weekend, but with mainly seasonal temperatures. Yesterday's highs were from around 5 to 10 degrees below average, with the warmest valley locations in the lower 90s while locations in the Mojave Desert rose to the mid to upper 90s. A slight warming trend is in store for the desert with a few locations returning to the century mark today and Sunday. The chances of a triple digit reading in this particular area are at 25-35 percent today and 50-60 percent Sunday. Breezy conditions will develop again this afternoon and evening in the prone areas towards the passes in the higher terrain adjacent to the west side of the San Joaquin Valley, Lake Isabella, and along the Mojave Desert slopes but with gusts generally below advisory levels. Dry conditions will otherwise prevail for the next 5-6 days.
By next week, temperatures will warm slightly with highs in the upper 90s by the middle of the week in the San Joaquin Valley. Although, there is a chance of triple digits (30-40 percent) in many valley locations, mainly Fresno southward from Wednesday through Friday. Highs will also be in the triple digits in the Mojave Desert; probabilities are generally 70-80 percent for Monday until next Saturday. There will be a lowering trend in humidity with the warmup through late next week, with minimum values lowering to the teens in the San Joaquin Valley and near 10 percent in the Mojave Desert by the middle of the week. The ridge of high pressure strengthens with its center returning to the Four Corners region, and a slight chance of thunderstorms returns to the Sierra Nevada crest by Friday and next Saturday.
