National Weather Service San Joaquin Valley - Hanford California
246 am PDT Sat Mar 15 2014
a ridge will provide dry conditions and well above normal
temperatures for the weekend. Warmest day will be Sunday
approaching near record levels in the San Joaquin Valley and
surface high pressure will build over the Great Basin today behind
an upper trough moving over the northern rockies. This will
provide a weak offshore flow and dry conditions across central
California through the weekend. Meanwhile an upper ridge along the
east Pacific will build inland over the west resulting in a warmer
air mass. Springlike temperatures will continue for the weekend
with near record highs possible on Sunday. An upper trough will
move into the Pacific northwest Sunday night. Models have trended
drier with this trough. However a strong upper level jet with this
system will likely provide breezy to windy conditions Monday
afternoon especially along the High Sierra and Kern County mountains
and desert. A dry northwest flow aloft will prevail across California
for much of next week. The 12z extended models and ensemble means
prognosticated a weather system bringing some precipitation mainly over
the Sierra Nevada Wednesday night and Thursday. However the 00z
models runs have trended weaker and drier with the upper trough
with no measurable quantitative precipitation forecast. Thus no drought relief for central
California over the next week or so.
VFR conditions will prevail over the central California interior
through the next 24 hours.
