Wider weather episode

A low pressure system dropped southeast across the Great Basin on February 15 as a northwesterly flow prevailed over our area. Upslope clouds banked up along the Tehachapi as the result of the persistent northwest flow and resulted in fog and drizzle across the Tehachapi valley between the late morning and early afternoon which adversely impacted travel along State Route 58. The fog lifted into a low cloud deck during the afternoon and visibility improved.
