Area Forecast Discussion
National Weather Service Sacramento CA
212 PM PDT Sun Sep 6 2020

.SYNOPSIS...
Dangerous, record-breaking heatwave will impact the region through
the weekend into Tuesday. Critical fire weather concerns will
return Monday night through early Wednesday with north to east
wind and low humidity. Smoke and haze from wildfires will continue
to impact air quality and temperatures.

&&

.DISCUSSION...
Strong high pressure will bring record heat to the interior
valley the today and Monday with temperatures 108 to 112 over the
central valley. Smoke, especially from the creek wildfire has
been impacting some of the temperatures so far today. The thicker
blanket of smoke is expected to continue to move northeast and
east during the afternoon clearing from the valley which will
allow temperatures to rapidly heat up this afternoon.

On Monday night a low pressure area moving south through the
Eastern Great Basin and Rockies will result in strong surface high
pressure developing over the Great Basin. This will bring breezy
to windy conditions late Monday night and Tuesday and high fire
danger to the region. The good news is that it will also bring in
some cooler air into the region. Have adjusted timing for
Excessive Heat Warning as a result dropping the Warning late
Monday evening for the mountains, central and north Sacramento
valley and adjacent foothills late in the evening since it will be
slow to cool off. Further south at this time will be borderline
for the warning to continue so have kept it going for now. The bad
news is that the cooler air will allow for stronger winds to
develop on Tuesday. Expect northerly winds for the valley around
15 to 30 mph with gusts up to 35 mph. The strongest winds will be
over the westside of the valley. Northeast to east winds for the
Mountains and foothills around 15 to 35 mph with gusts up to 50
mph. Local favored locations will likely have stronger winds and
the lighter winds are expected over portions of the lower
elevations of the motherlode. The winds will decrease Tuesday
night for most areas but will increase once again in the mountains
and foothills for areas prone to easterly winds.

Lighter winds on Wednesday will remove the high fire danger.
Temperatures will generally cool slightly over Tuesdays highs in
the north and mountains with a little bit better cooling over the
southern valley and delta areas.

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...

temperatures with them running about 5-10 above normal. Upper
level ridging slowly pushes east into next weekend but will still
dominate our weather.

smoke. Winds remain below 10 knots.
