300 am pst Fri feb 22 2019

Synopsis
Brisk north winds decrease today. Next chance of precipitation
will return over the weekend and continue into next week.

Discussion
Clear skies cover the region early this morning as clouds are
limited to areas east of the sierra crest. Current temperatures
are chilly across most of the region, ranging from the teens and
20s in the mountains to the 30s to around 40 through the central
valley. Breezy northerly winds continue along the western edge of
the sacramento valley holding temperatures in the mid 40s. Areas
of frost will be likely along the eastern edge of the valley where
the north winds have been lighter.

Dry weather will continue today as the region will be under
short-wave ridging between systems, the first exiting socal and
moving into arizona and sonora while the next upstream system
drops down the british columbia coast.

The upstream low is forecast to stall over the pacnw during the
weekend as the omega block sets up along 140w-150w. Flow breaking
under the block will bring light amounts of precipitation to
mainly the northern half of the forecast area on Saturday and
Sunday. A weak to moderate ar is then forecast to transit norcal
from later Sunday through Monday bringing a better chance of
precipitation across the region.

.Extended discussion (Tuesday through Friday)
the forecast remains on track this morning, with an active
weather pattern continuing to look likely for the extend portion
of the forecast. Wet weather starts Monday as a low slides into
southern or and northern ca, tapping into some tropical moisture
bringing widespread valley rain and mountain snow to the region.

This system will continue to linger over the area through Tuesday;
however, models still struggle with how far north or south it
will go. The latest data suggests that precip will last into
Wednesday, but once again, the ECMWF and the GFS are not in
agreement with timing and strength.

Beyond Wednesday, models continue to struggle with the forecast
but northern ca may experience a brief period of dry weather on
Thursday. For Friday, models are hinting at large low moving into
the region which could bring another round of rain and snow.

Aviation
Northerly winds will prevail today, before becoming light and
variable as we head into the evening and overnight hours.VFR
conditions are expected.

Sto watches warnings advisories None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
