Weather Discussion for Wednesday June 12, 2019

Normal high/ low temperatures for June 10-June 17  (high/low) Redding 91/62 Chico 90/57, Quincy 81/42, Chester 76/40, Susanville 79/46, Grass Valley 80/51, Weaverville 84/44, Mt. Shasta 77/45 Yreka 80/45, Alturas 77/41

High pressure is along the coast.   Over the next few days this high will move a little to the west (see map below).   This morning's satellite picture (below) shows some sub tropical moisture has moved northward over the Sierras.  This moisture will fuel afternoon cumulus clouds over the mountains through Friday with isolated thunderstorms possible north and east of Redding.   Temperatures will continue 8 to 12 degrees above normal.

Saturday through next week the high will continue to dominate our weather.   We will see sunny skies with continued above normal temperatures.  Gusty north winds are expected Sunday through Tuesday.

  1. If the HP has a clockwise movement what is pushing the subtropical moisture nord?
    Thank u

  2. It was hard to show on the map but there is a very very weak upper level low pressure area passing under part of the ridge which had enough strength to pull some moisture north. Nice catch.

    1. Can u recommend any chart that can be used to see these upper level low pressure thanks
