Area Forecast Discussion National Weather Service Sacramento CA 310 AM PDT Thu Jul 9 2020

SYNOPSIS. Dry weather with seasonably hot temperatures for the next week.

DISCUSSION. Clear skies cover the region early this morning. The Delta Breeze is a bit stronger early this morning compared to early Wednesday, and current temperatures are running a bit cooler compared to 24 hours ago where its influence is present. Elsewhere, current temps are running slightly warmer compared to yesterday.

Hot and dry weather will continue across the region through the upcoming weekend. Temperatures will remain a little above average today and Friday, then warm a bit over the weekend as ridging over the Southwest extends slightly north and westward. Highs over the weekend are forecast to be around 5-10 degrees above average with much of the Central Valley in the 100 to 105 range beginning Saturday and continuing into early next week. At least a trickle of a Delta Breeze is expected to continue over the weekend which will help overnight lows in the valley to make it down into mostly the 60s to lower 70s. Heat risk looks like it will stay mostly in the low to moderate category into early next week.

EXTENDED DISCUSSION (Monday THROUGH Thursday). Upper level troughing will remain in place over the PacNW for the extended period with upper level ridging over the four corners region. This will bring zonal to slight troughing over NorCal and keep a quiet weather pattern in place. Highs will be warm running 5 to 10 above normal for the start of the period but will fall to near normal by the end of next week as more troughing builds over the west coast. Some light north winds are expected Tuesday, otherwise we will see light onshore flow except through the Delta where gustier winds are expected. -CJM

AVIATION. VFR conditions the next 24 hours. Winds remain under 10 kts except thru the Delta where gusts up to 25 kts will be 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.
