What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

726 pm pdt Wed jun 20 2018

Short term Showers and thunderstorms developed this afternoon
across the region associated with an upper level trough and
strong short wave. The activity continues this evening with
storms moving slowly northeast. Up to this point most reports
have been heavy rain, small hail and gusty winds to 40 mph. With
strong dynamics aloft expect showers and storms will continue into
the overnight period. High temps today were in the 80s to mid 90s
and with cloud cover increasing it will likely be a warm night.

Lows in the upper 50s and 60s. The upper trough will be over the
forecast area through afternoon with showers and thunderstorms as
the airmass will remain unstable. The trough moves east into
idaho by evening and expect activity should decrease quickly.

Temps will be about 5-10 degrees cooler. Fair weather Friday with
a weak upper level ridge over the area. 94

Marginal risk of severe thunderstorms through this evening...

short term... Tonight through Saturday... A shortwave is moving
onshore northern ca early this afternoon. Ahead of this feature,
initial showers thunderstorms have developed across southern
sections of central or. Coverage and intensity of storms will
increase through the afternoon as peak heating is reached. High
resolution models continue to show the thunderstorms forming into a
complex early this evening, moving northward late evening overnight.

Will use the highest pops across central or and the associated
highlands, with less coverage further north through the evening with
some increase in coverage overnight as the shortwave moves gradually
to the east. With sufficient deep layer shear through at least
early this evening, strong to locally severe storms will be
possible with gusty winds and hail the main threats. Thunderstorm
coverage will decrease some overnight, but at least a slight chance
of storms will linger with residual instability. Lows tonight will
be unseasonably warm, especially north of central or, with lower
elevation lows in the mid 60s to around 70.

The shortwave will continue to move east Thursday, exiting the
area Thursday night. Pops will remain quite high from the blue
mountain foothills eastward with likely pops through Thursday
afternoon. With some instability, chances of thunderstorms will
continue. With the greatest shear to the east, do not expect
strong severe storms Thursday. Areas to the west will experience a
slight chance of residual showers early, ending by afternoon.

Residual activity in the evening across the eastern mountains will
end by the overnight as shortwave ridging drier NW flow enters
the region. Dry conditions will prevail Friday and Saturday under
nw flow. In the wake of the system, windy conditions will prevail
on Friday Friday evening with some local gusts approaching
advisory criteria. Above normal temperatures Thursday will cool
slightly Friday and Saturday.

Long term... Saturday night through Wednesday... Saturday night an
upper trough will be departing the area while an upper ridge
builds along the coast. Do not expect any precipitation Saturday
night except perhaps in eastern wallowa county in the early
evening but have gone with dry forecast. Sunday will see the ridge
move overhead for a dry and warm day with highs in the 80s and
lower 90s. The ridge will move off to the east Sunday night as a
trough moves to the coast. The trough will move east gradually and
come ashore Monday night and then through the area Tuesday. Most
of the energy and moisture with the trough will remain up in
british columbia so our area should remain dry. The trough will
bring breezy west to northwest winds of 10 to 20 mph Monday in the
late afternoon and evening. After the trough departs on Tuesday
models have some timing differences but it appears that a westerly
flow will be over the area on Tuesday night followed by a weak
trough that arrives Wednesday. All models continue fair and dry
weather Tuesday night and Wednesday. After the warm day on Sunday,
temperatures will drop back to the mid 70s to mid 80s Monday and
then to the mid 70s to lower 80s with mid 60s to mid 70s in the
mountains on Tuesday and Wednesday.

Aviation... 00z tafs...VFR conditions will be prevalent for the
next 24 hours. Scattered thunderstorms have developed over central
oregon and the ochoco-john day highlands this afternoon and will
continue through 04z followed by a couple more hours of rain showers
at krdm and kbdn. Thunderstorms and showers may also get into kdls
and kykm from 02z-08z. Believe that at kpsc, kalw and kpdt, bands of
precipitation from dissipated thunderstorms will bring showers from
07z-17z. Brief MVFR ceilings and MVFR ifr visibilities with gusts to
35 kts are possible with thunderstorms. Skies will be clearing after
18z. Winds will generally remain under 15 kts through 18z tomorrow
morning then will increase to 10 to 20 kts with gusts to 25 kts at
kdls, kalw, kpsc and kpdt.
