Area Forecast Discussion
National Weather Service Sacramento CA
330 AM PDT Sat Aug 15 2020

.SYNOPSIS...
Prolonged heatwave will impact the region through the middle of
next week. Daytime temperatures will be 10 to 20 degrees above
normal with limited overnight relief. Slight chance of afternoon
showers/thunderstorms over the mountains this weekend into
Monday.

&&

.DISCUSSION...
Water vapor imagery this morning shows fairly dry conditions of
northern CA as we remain trapped between high pressure over the
desert southwest and a closed low over the Pacific. Guidance
continues the same trend noted by the evening shift, where
heights/thicknesses for tomorrow have increased by 1 to 2 degrees
C at the 850mb level. Opted to start with yesterday's temperatures
and then nudged them up by a few degrees. Most climate sites have
the chance to either tie or break records if the forecast pans
out. Highs for the Valley are forecast to range from 105 to 112
degrees while the foothills range from 95 to 105. Not much more
relief will be found in the higher elevations either as temps
range from 85 to 95 degrees. In addition to the heat tomorrow,
models continue to show elevated instability which could lead to a
slight chance of afternoon showers or thunderstorms over the
higher elevations of the Coastal Range and Sierra Nevada.

Saturday night and into Sunday, the offshore closed low will move
a touch closer to the north coast. Models are hinting at height
falls and short wave trough sliding coast. Temperatures will
likely reflect Friday's forecast, but there's some concern about
potential cloud cover. Guidance from the CAMs suggest the chance
for showers and thunderstorms; spreading from south to north
Sunday morning and into the afternoon. PWATs are around an 1 inch,
but the moisture is found in the upper levels. Should convection
occur, isolated dry thunderstorms are not out the question for
portions of interior NorCal. As a result, have issued a Fire
Weather Watch for this threat as fires could rapidly grow given
the heat, primed fuels, and unstable nature of the atmosphere.

Beyond Sunday, there is a slight chance for thunderstorms over the
Sierra and southern Cascades. If storms form they should stay
confined to the terrain. Heights are forecast to rise Monday and
Tuesday as high pressure builds over the Great Basin area. High
temperatures will generally be in the 105 to 110 degree range for
the Valley. Unfortunately, we won't see much in terms of
overnight relief as highs will span the 70s and 80s until
midweek. As a reminder this is a significant and dangerous heat
event. Heat related illness to humans and animals is likely with
extended outdoor exposure. Heat is the number one weather-related
killer in the U.S. Take necessary precautions to stay hydrated,
cool, and safe during this prolonged heatwave.

&&

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)...

Ensembles in general agreement weakening the center of strong
high pressure, and shifting it eastward from southern Nevada back
toward the Four Corners region later next week as a trough
approaches the PacNW. The result is expected to be a gradual
easing of temperatures across interior NorCal, back to only
around 5 degrees above average by next weekend. Deeper moisture
and instability is forecast to be east of the region.

&&

.AVIATION...

VFR conditions next 24 hrs. Isolated afternoon thunderstorms
possible over higher elevations of the Coast Range and northern
Sierra Nevada 21Z-03Z. Isolated high-based thunderstorms possible
after 06Z Sunday. Surface wind generally below 10 kts.
&&

.STO WATCHES/WARNINGS/ADVISORIES...
