Area forecast discussion
National Weather Service San Joaquin Valley - Hanford California
357 PM PDT Thursday may 23 2013
Synopsis...
low pressure over the Pacific northwest is bringing a cool onshore
flow to the central California interior. Temperatures will remain
near normal through early next week.
&&
Discussion...
in the short term...the main concerns have been the gusty
conditions in the Kern desert and Tehachapi Pass areas and the
cooler temperatures. With a northwest flow in place above US winds
are flowing over the Tehachapi Mountains and sinking on the
eastern slopes making for gusty conditions especially in the
Mojave area. A Wind Advisory is in effect there until 9 PM this
evening but my relief will need to monitor the situation for
possibly temporally extending the advisory. As far as the cooler
temperatures go the San Joaquin Valley will again have another
cool morning with lows in the middle to upper 40s. With winds
virtually non existent today compared to yesterday mixing will be
minimized and along with mostly clear skies radiational cooling
will therefore be maximized. Some areas could potentially flirt
with near record low temperatures.
Temperatures will gradually and slightly be on an upward swing
for the remainder of the week and over the weekend but will
continue to remain near normal. Skies will also remain mostly
clear through the weekend. With an Omega block firmly in place
over the central U.S. A system over the Pacific west which has been
spinning in place for the last few days will begin to move
southward and will increase the clouds and cool temperatures
beginning Monday. The only question is will any precipitation
occur. At this time the current thinking is that with little
atmospheric moisture present measurable precipitation will be
unlikely. However...having said that there will be a good chance
for very light sprinkles especially Fresno northward Monday night
through Tuesday. With shortwave impulses moving through the area
temperatures next week will remain well within normal ranges and
clouds will be more likely.
&&
Aviation...
wind gusts of 35 knots or greater can be expected through and below
the mountain passes of Kern County through 04z Friday. Otherwise...
VFR conditions will prevail across the central California interior.
