.KEY MESSAGES...
1. Dry and windy conditions create significant
fire risk this weekend, particularly in Eastern Kern and
Southeastern Tulare Counties.

2. Below normal temperatures continue across the area.

3. Practice safety around lakes, rivers and streams, as water
is still running cold.

.DISCUSSION...
The large area of low pressure troughing over the western US
will continue to support gusty afternoon and evening winds
today. This will particularly be the case along the Mojave Slope
(~40MPH gusts) and San Joaquin Valley north of Visalia (~20MPH
gusts), where latest NBM and HREF guidance from this morning
indicates winds will approach (but not meet) Wind Advisory
thresholds. This sentiment is subject to change following newer
model guidance and continued monitoring of surface observations,
however. Whether a Wind Advisory is issued or not, dry air
across the region still presents an elevated fire risk when
combined with the afternoon and evening winds. This pattern is
likely to continue into tomorrow, as a small low pressure
anomaly within the larger troughing pattern quickly slides
across our region from the Pacific Northwest.

Below normal temperatures are expected to continue into the next
7 days as the trough remains aloft, though with weaker winds due
to a less intense pressure gradient in said trough. RH`s will
also remain in the teens to single digits in the desert and dry
out in the Valley into the 15-25% range. By next weekend, it is
expected to move east and ridging will begin building in its
place. This will lead to a warm-up in temperatures throughout
the region, and will approach the seasonal normals for this time
of year. Long term models have this ridge gaining strength and
above normal temperatures gaining a foothold once again by the
week after next, which is also seen by the Climate Prediction
Center as they have our area in the leaning above normal
temperatures category for the 8 to 14 day outlook.
