Area forecast discussion

Synopsis...a warming trend will take place through at least the
middle of next week with above normal temperatures all of next
week. Dry weather will persist across central California through
Discussion...today will be characterized with relatively cool
weather. However, high pressure ridging will be the dominant
feature beginning Sunday and continuing for the next several days.
Thus, a warming trend with dry conditions is in store for next
week. We anticipate above average temperatures by Monday and will
continue for much of next week, although a slight lowering in
temperatures is in store for Wednesday and the end of the week due
to a weakening in the longwave ridge pattern. Nonetheless, warmer
than average temperatures will likely continue through next
weekend as the high pressure ridge is forecast to rebuild over the
western U.S., And models are in decent agreement in keeping this
high pressure ridge parked over the western states.
Besides the overall high pressure pattern, one feature to note
for at least Monday and Tuesday, will be another episode of
offshore, or easterly, winds over the mountain areas, especially
south of Sequoia np. This is not an unusual or uncommon pattern
during this time of year, although precipitation has remained
well below average during the last 30 days. At this time, it does
not appear winds will be strong enough, nor does it appear
relative humidity will be low enough for a sufficient duration
over a widespread area to warrant highlights for our area.
However, this particular pattern still bears watching over the
next few days as many areas received little or no precipitation
even with the recent storm.
Otherwise, a warm and benign weather pattern will likely continue
through next weekend.
VFR conditions are expected to prevail during the next 24 hours
across the central California interior.
