a warming trend will continue through the week and into the weekend
as high pressure builds over the area. By Thursday...daytime high
temperatures through the valley will reach above normal values with
this trend continuing into at least early next week.
some middle level clouds along and east of the Sierra this as morning
as an upper level low digs south over California. Otherwise mainly clear
skies across the central California interior. Wind flow will turn
north and offshore today as surface high pressure builds towards
the Pacific northwest in the wake of the upper low. The wind flow will
turn stronger offshore tonight over central California as the high
builds southeast in the Great Basin. This will set up a Santa Ana wind
pattern over scal by the end of today and overnight. The offshore
flow will continue into the weekend as another cold upper low
moves through the north rockies and supplements the Great
Basin surface high. Models show the stronger pressure gradients
developing tonight across southeast California. The stronger offshore winds
should develop tonight through Thursday morning. Expect gusty east
winds especially through the Kern County mountains overnight into
Thursday morning. At the same time a ridge over the coast will
build inland over bringing above normal temperature by Thursday.
The downsloping wind flow will provide warmer and dryer conditions
Thursday and Friday towards the south end of the valley and valley
slopes of the Kern County mountains.
The medium range models and their ensemble members are in
excellent agreement in keeping the ridge in place over the western
Continental U.S. Through the weekend and into the early portion of next week.
As a result...dry weather and unseasonably warm temperatures are
expected to prevail across our area through at least the middle of
Aviation... VFR conditions will prevail throughout the central California
interior during the next 24 hours.
