DISCUSSION

Key Points:

* Above normal daytime temperatures Thursday through Saturday * Chances for showers and slight chance for thunderstorms on Saturday, with highest chances across Northern California * Chances for showers Sunday and cooler temperatures. * Showers linger into Monday

The upper low has moved east of the area. Skies will gradually clear this morning and early this afternoon. Expect cool morning temperatures, followed by high temperatures slightly above normal. This pattern will continue on Friday with daytime temperatures trending warmer. Some localized morning frost is possible on Friday in western valleys, such as in the Illinois and Applegate valleys.

A weak upper low moves into northern and central California Friday night and Saturday. Meanwhile a broad trough associated with a low to the northeast over Canada settles over the region. Models and ensembles show moisture moving up from the south and into the area on Saturday with chances for showers (20-50%) and slight chances (10-20%) for thunderstorms. These chances are highest across Northern California. However, showers may extend northward into portions of southern Oregon, especially from the Cascades east.

The upper low to the south moves eastward Saturday night but a broad upper trough remains in place Sunday into Monday. This pattern with bring additional showers to the area. Highest chances for showers (30-60%) are expected from the Cascades east and over northern California with less chances (15-30%) west of the Cascades in southwest Oregon. The National Blend of Models indicates a low chance (10%) for isolated thunderstorms on Sunday and Monday as well. Temperatures will trend cooler on Sunday and Monday with near or slightly below normal highs.

For Tuesday and Wednesday, ensembles favor warmer temperatures and low chances (5-20%) for showers.
