area forecast discussion

306 pm pdt Mon jul 22 2019

Synopsis
Hot temperatures this week with widespread valley temperatures
near 100 degrees. There is a slight chance of thunderstorms over
the central sierra late this week, though they will likely remain
east and south of our forecast area.

Discussion
Another hot day is expected today for interior norcal as the area
remains between strong high pressure centered over the desert
southwest and low pressure off the pacnw. Current temperatures
are around 5 to 8 degrees warmer than this time yesterday. Valley
temperatures will peak right around the century mark.

The weak trough pushing through the pacnw tomorrow will brush
norcal. This will increase onshore flow and create breezier winds,
keeping temperatures a few degrees lower than today. There are no
major fire weather concerns with these winds as they will be from
the south to east and gusts will only be around 15 to 20 mph.

Ensemble models continue to expand the monsoon high slightly
northwestward Wednesday and Thursday, though they have
continually backed off on the extend of the expansion. Flow will
become southwest over the forecast area, bringing some monsoon
moisture around the high. There is a slight chance of sierra
thunderstorms over the far southwest corner of our forecast area,
though they are likely to remain east and south of our area.

Temperatures will warm a few degrees back to near 100 degrees
across the valley. A slight delta breeze is expected to continue
each night, allowing overnight temperatures in the valley to
mostly remain in the 60s. Hec

Extended discussion (Friday through Monday)
High pressure over the desert southwest will continue to
influence our region as it slowly edges westward. Southwest flow
aloft should mostly keep monsoon moisture east of the forecast
area. However, there is a very slight chance of precipitation in
eastern tuolumne county on Friday.

Warm and dry conditions are expected across the region through
next week. Temperatures are forecast to be around normal for this
time of year. This weekend could be a few degrees above the
climatological average with several locations expected to reach
into triple digit temperatures. Sll

Aviation
Vfr conditions next 24 hours. Local southwest wind gusts 15-25 kts
near ksuu, otherwise sustained winds less than 15 kts. Southerly
winds increase tomorrow afternoon in the north valley with gusts
up to 20 knots possible.

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.
