area forecast discussion

845 am pdt Sat jul 22 2017

Discussion The latest visible image shows clear skies over most
of the forecast area. The exception is from about brookings south
where marine stratus has been creeping slowly north towards
brookings. It could sneak into brookings for a hour or two this
morning, otherwise it will remain clear. Temperatures on average
will be 3-5 degrees warmer then yesterday for inland locations. At
the coast they will be similar to yesterday. Made some adjustments
to the sky cover to reflect the latest satellite image.

The main concern ahead will be thunderstorms from Sunday
afternoon through at least Wednesday. Please see previous
discussion for details on this. -petrucelli

Aviation 23 12z TAF cycle... Except for the coastal waters
beyond 20 nm and the extreme southern coast up to brookings, the
region will remain clear with offshore flow at the coast. North
winds are expected to gust to near 30 knots at the coast this
afternoon and evening. Fb

Marine Updated 200 am pdt Saturday 22 july 2017... The thermal
trough will strengthen overnight through the weekend, and by
Saturday morning will be producing gusty north winds and steep seas
south of gold beach this morning, with hazardous areas expanding
north to CAPE blanco this afternoon. Winds and seas will strengthen
even more tonight and Sunday, with gales and very steep and
hazardous seas developing over much of the area. The thermal trough
will persist into early next week, though it will weaken Tuesday and
Wednesday. -fb

Prev discussion issued 634 am pdt Sat jul 22 2017
discussion... High pressure will provide dry, hot and sunny
weather today with another similar day on tap for Sunday. Many
areas across the rogue, illinois, and lower klamath river valleys
will be hovering around the century mark - so be careful out there.

Chill out and take a drink of cool water. Relax in the shade.

Also, wear your life preservers in those chilly lakes and rivers!
that water can be a little too cold for comfort and can lead to
troublesome swimming.

Late in the day Sunday the region will come under the influence
of a closed upper low that moves into position just off the
northern california coast. Abundant cumulus and some late day and
evening thunderstorm chances are on tap for areas from northern
california and along the cascades. Atmospheric moisture in these
areas will be fairly low so some dry lightning is possible. Over
the west side from near brookings to grants pass, medford and
ashland, there will be a slight chance for storms and these would
contain higher moisture as models are showing nearly an inch of
precipitable water. Some storms and or showers may continue
overnight.

Not a whole lot changes into Monday but the atmosphere should be a
little juicier so storm coverage is expected to be greater. The
upper low will stay put but should be wobbling around a little of
cape mendocino into Monday night. Nocturnal storms again are
probable and or lingering overnight showers and some remaining
cloud cover.

And... The thunder threat will continue into Tuesday as the upper
low heads inland over northern california. The ec model wants to
move the low through a bit quicker than the other solutions, but
it looks like the low may hang around long enough to warrant
mentioning thunder across some areas even into Wednesday as well.

For now we're leaving Wednesday alone. Stavish
fire weather... Updated 630 am Saturday 22 july 2017... There are 3
main items of interest in the forecast: easterly winds with moderate
ridge top humidity recoveries today including a moderate to strong
chetco effect near brookings today and Sunday, hot inland
temperatures through Monday, and especially a chance to chance of
thunderstorms Sunday afternoon through Tuesday evening including the
possibility of overnight thunderstorms.

Humidity recoveries will be at their worst this morning, but not so
poor as to warrant issuing any warnings. Northeast winds will become
breezy this morning and will be at least as strong on tonight, but
humidity recoveries will not be as poor due to increasing dew
points.

The hotter temperatures and increasing moisture are accompanying the
approach of an upper level trough to the northern california coast.

This is a classic pattern for the development of thunderstorms in
our area. Mid-level moisture will increase from the southeast. The
slight chance of thunderstorms begins on Sunday afternoon... Except a
better chance in the vicinity of crater lake. There is also a
slightly enhanced risk for the higher terrain from modoc county
northwestward across south central oregon fire weather zone 624.

Thunderstorms on Sunday are likely to be neither especially dry or
especially wet. There is a lingering slight chance of showers and
thunderstorms overnight into Monday with a shortwave disturbance or
two likely to track across our area.

The probability and coverage of thunderstorms are expected to be at
a peak on Monday evening. The increase in instability will be
accompanied by an increase in moisture. There is substantial model
difference in which areas will have the highest probability of
thunderstorms, but general agreement on widespread coverage that
includes most of SW oregon down to the coastal zones of curry
county. With the upper low forecast to still be centered over the
northern california coast, there is a high probability of isolated
nocturnal thunderstorms Monday night. The risk will continue on
Tuesday though perhaps with the highest probability east of the
cascades as the low pushes slowly eastward.

As a result we have issued two fire weather watches, both for
abundant lightning and dry fuels. The first one is for Sunday
afternoon through Sunday evening and will affect an arc of an area
from the warner mountains then NW into the fremont-winema nf into
the crater lake and eastern umpqua nf. The second fire weather watch
for Monday covers a wider area and includes most of zones 624 and
625 in oregon and 285 in california, and the cascades and eastern
zone 622 in jackson county.

Be advised that thunderstorm potential covers a much larger area
than described in the fire weather watches. The watch area reflects
our forecast where lightning coverage equals to or exceeds lal of 3.

Thunderstorm threat appears over by Thursday as the low is forecast
to move east of the forecast area and westerly flow develops over
the area. This however will likely lead to breezy west winds during
the second half on next week. Fb
