.DISCUSSION...
Low pressure troughing aloft continues to cause below normal
temperatures and elevated winds throughout the region, with the
strongest winds along the mountain ridges and into the Mojave
Desert Slopes. Along with these winds, dry air will continue to
lead to lowered afternoon RH`s especially in the Mojave Desert,
which will continue to see low teens into the single digits
through the week. This will lead to an elevated fire risk,
though because the winds won`t be as strong as the winds seen
over the last few days, red flag conditions are not likely to be
met. Tomorrow afternoon, a strong shortwave rotating around the
trough axis may provide a small amount of energy and moisture,
enough to develop some isolated thunderstorms along the Sierra
Nevada crest, mainly north of Madera County and at the highest
elevations. Current chances for thunderstorms are 10-15%
tomorrow afternoon.

This troughing is expected to stick around over the west coast
through the week and may begin to weaken by this coming weekend
as ridging from the south may raise 500mb heights over Southern
and Central California. As the ridge strengthens, temperatures
will become above normal once again, with the Valley in the
upper 90`s by next weekend. The Climate Prediction Center also
has the CWA in leaning above normal temperatures for the 8 to
14 day outlook due to this possibility.
