.DISCUSSION...

...Today-Monday...
Mostly clear skies, along with afternoon temperatures climbing
into the mid to upper 60s at the time of this writing prevail
across interior NorCal. Low pressure off the coast of Baja
California, and upper level ridging strengthening in the eastern
Pacific have allowed for light southerly winds to develop, with
winds much weaker compared to yesterday`s breezy to gusty
afternoon. Monday we will see similar weather conditions across
the area as the low pressure to our south will begin to slowly
move east. While no precipitation is expected, some elevated
instability may make its way into the portions of the Sierra,
mainly south of US50. Chances are less than 5% for precipitation
or thunder and therefore not in the official forecast, but the
small chance is worth noting.

...Tuesday-Saturday...
As the low moves further east on Tuesday, we will see high
temperatures slightly cool across the region, although they will
still be above-normal. By mid-week, EPAC ridging strengthens and
will remain in firm control of the weather pattern. High
temperatures will climb back into the mid to upper 70s and
eventually breaking the 80 degree mark by the weekend. With the
above normal temperatures, HeatRisk products are beginning to make
their way into the forecast. By this weekend, Minor HeatRisk is
likely across most of the Valley and into the foothills. As a
reminder, warmer temperatures will likely lead to increased water
activities, so if you plan on hitting the local waterways, expect
very cold water temperatures, always wear a life jacket, and cold
water can cause hypothermia causing even experienced swimmers to
quickly lose muscle control.

.AVIATION...

VFR conditions are expected over the next 24 hours, with winds
less than 12 kts. Additionally, there is a 15 to 30% chance of
patchy MVFR conditions due to low cloud development in the Valley
between 12 and 15Z Monday.
