228 pm pdt Wed apr 18 2018

Synopsis
Light showers mainly over the mountains through Thursday. Low
snow levels with slippery roads higher elevations. Dry Friday
through early next week. A few showers possible over the northern
mountains middle of next week.

Discussion
Upper level low will drop south to near the bay area this
evening. Not much moisture associated with this system and its
quick movement will limit the time to pick up any additional
moisture. Despite a few radar returns this afternoon... Precip is
not reaching the ground at valley locations. Have seen light snow
begin during the past hour over the sierra along interstate 80
from blue canyon to donner pass and a period of light snow will be
possible through 8 pm then there should a break this evening.

Accumulations through the early evening should not be more than an
inch.

A few scattered mountain snow showers will continue into Thursday
afternoon with up to 2 inches of total accumulation... Best
chances south of interstate 80. Snow levels will be be drop to
4500 feet so there could be a few slick spots at pass level
overnight. High pressure builds behind the system on Friday with
dry and warmer weather returning through the weekend. Valley high
temps on Friday will be in the upper 70's and low 80's and low to
mid 80's for Saturday.

.Extended discussion (Sunday through Wednesday)
high pressure ridging will bring dry and warm conditions over the
weekend. Weak disturbances will flatten the ridge somewhat
bringing some high cloudiness to the region Sunday but daytime
high temperatures will remain well above normal. A weak
disturbance will bring just slightly cooler temperatures Monday
and Tuesday. An upper low along the coast will approach Wednesday,
bringing the potential for some showers over the mountains. Ek

Aviation
Vfr TAF sites next 24 hours. Winds generally below 10 knots.

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.
