the spell of 70+ degree temps has ended for the time being, with the
airmass behind yesterday`s cold front shaving off about 10 degrees
in high temps going into the weekend (low to mid 60s, maybe a few
upper 60s by monday). drier low levels remain in place with
dewpoints in the 40s and surrounding soundings shows fairly dry
conditions below 850 mb. hi-res models continue to show some
spurious light showers/sprinkles for later this afternoon into
sat afternoon as an elevated warm front attempts to work north
towards the region. 295-305k isentropic surfaces show decent
lift and low cpds, but then impacts of dry air below that leads
to a lower confidence forecast on measurable precip. northern
areas will be on the edge of the rrq of a 90 kt jet streak which
may help give a little more kick to the lift. model blend has
backed off on timing of arrival overnight with differences in
models on where and when some light shower activity could take
shape with some indications of a diurnal uptick by the hrrr/rap
in the afternoon. will continue with no more than chc pops into
saturday afternoon with best chances on saturday. hopefully,
whatever is around will be gone by the time trick or treaters
hit the streets.
trough currently moving onshore in s california will move northeast
in a weakened state, but will enough lift to bring another chance
for showers sunday afternoon, possibly lingering into monday.
thereafter, the deeper trough that has been discussed at length for
days will become the main challenge through much of the upcoming
week with focus on mid week. energy is still on the edge of the best
upper air sampling, but hopefully better agreement starts over the
weekend into early next week as it moves east. best signals still
point towards mid week being on the wetter side, but the main upper
low may remain sw of the area. while severe weather threat may be
low, still expected one or more rounds of precip. the active pattern
will likely persist into next weekend, but low confidence exists
given the plethora of differences in models.

vfr conditions expected through this taf period. did add mention
of prob30 for light rain showers for ksbn after 12z sat however
confidence is not high as guidance has been hinting that the
better precipitation chances may stay further west. do think
that it would not be impossible that a few sprinkles or showers
may make its way into ksbn area tomorrow. light easterly winds
are expected to continue through this forecast period.
