342 pm pdt Thu jun 22 2017

Synopsis
Extended heat wave with widespread highs over 100 degrees and
warm nights through the end of the week. Isolated afternoon
thunderstorms possible over the mountains. Not as hot next week.

Discussion
Current temperatures ranging 104 to 108 in the valley at 3 pm and
those numbers will climb higher in the next several hours. Yesterday's
peak heat occurred near 5 to 6 pm. Will have to monitor record
highs for several locations. For example, modesto is currently at
105 degrees and their record is 106 (1954). Downtown sacramento is
at 105 and the record is 107 (1981). Redding is at 106 and the
record is 107 (2006).

Northerly winds have picked up this afternoon with strongest
winds over the north and west side of the valley. The high heat,
low relative humidity and increased winds will continue high fire
danger as the red flag warning continues.

Thunderstorm chances likely to be limited to the sierra south of
lake tahoe over the next few days.

Hot weather continues across the northern half of the sacramento
valley and in the mountains late this week while cooler weather
gradually returns to the delta and southern sacramento valley as
the delta breeze returns.

.Extended discussion (Monday through Thursday)
temperatures continue to cool Monday and Tuesday as an upper
level shortwave trough pushes the ridge axis east. Upper flow will
be mostly zonal over the area, so high temperatures will still
mostly remain a few degrees above normal through midweek. However,
low temperatures will finally fall to normal by Monday night due
to southerly winds and breezy delta winds which will finally allow
overnight relief from the heat in most areas. Dry weather
expected for interior norcal beginning Monday as the airmass
stables.

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.
