929 PM PDT Mon Mar 30 2015

Cooler but still above normal weather expected this week. Weak
weather systems may bring a few intermittent showers to the
mountains Tuesday and Wednesday along with cooler temperatures.
Another chance of precipitation arrives next weekend.


A system along the coast is bringing high clouds and gusty winds
through the delta and over the ridges.

On Tuesday that weak system will pass by to the north and may
bring a few showers over parts of Shasta County. Areas to the south
will be remaining dry but much cooler by 8 to 15 degrees with the
greatest cooling occurring in the mountains. Northerly winds are
expected to develop during the day and should become breezy over
the north by late morning before impacting the southern areas.

Another shortwave will move through the area on Wednesday but the
greatest impact looks to be keeping temperatures cool over the
region. Some showers look possible over the mountain areas late in
the day and through the evening hours before any threat diminishes.

On Thursday with the system well east of us we will start to warm
a little. Breezy northerly winds will occur throughout the valley.
Some winds along the west side of the valley may reach wind
advisory criteria.


.Extended Discussion (Friday through Monday)

High pressure remains in place Friday and could result in
continued breezy north to northeast winds. Longer range models
are suggesting a transition to a cooler and unsettled pattern
this weekend and early next week, with improving confidence. The
exact strength of this this system is still not certain, but the
potential for some showers and cooler temperatures is looking
higher. The ECMWF and GEM continue to be wetter than the GFS, and
bring the potential for a more extensive, widespread system
through early next week. Snow is even a possibility with this cool
system, especially if the ECMWF is on track. Will be watching to
see how this system evolves over the coming days. EK



VFR conditions will continue the next 24 hours. Next system may bring
light showers to northern mtns late tonight into Tue. Gusty winds
through the delta and over the mountains with gusts around 25 kts
in the delta and 40 kts over ridges.
