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.

Synopsis Isolated showers and a thunderstorm or two will be
possible around the trinity alps this afternoon. Otherwise hot
and dry conditions will prevail across northwest california this
week. The exception will be at the coast, where cooler
temperatures will accompany nighttime and morning clouds and fog.

Discussion An upper-level trough continues to lift east-
northeastward over oregon and idaho later this afternoon.

Lingering forcing and instability associated with this trough will
likely help spark a few robust showers or even a thunderstorm or
two around the trinity alps this afternoon. The activity should
not product too much lightning or heavy rain, as was the case on
Sunday afternoon. Aside from this localized precipitation this
afternoon, expect dry weather for our region for the next several
days, with the focus turning to heat for inland areas.

Temperatures once again breached 100 degrees for some of the
interior valleys, including ukiah, covelo, hoopa, hayfork, and
douglas city to name a few. High pressure aloft centered across
the southwestern united states will build following the
aforementioned trough, and that will only result in hotter
temperatures tomorrow and Wednesday, so the heat advisory for interior
mendocino, del norte, humboldt, and all of trinity county will
remain in effect. This kind of heat, although not uncommon for
our region in mid- summer, will present a risk to anyone sensitive
to hot temperatures, as well as even healthy and strong folks who
have to spend long periods of time outdoors exposed to the sun.

Take necessary precautions and do not underestimate this heat.

Some upper-level troughiness tracking southward out of the gulf of
alaska and toward the pacific northwest later this week may try to
put a slight dent in the heat. However, the latest model guidance
appears to keep the dome of hot weather holding strong across
california and the southwest into the end of the week. Thus, later
forecasts may need to bump temperatures up and extend heat
advisories for Thursday and Friday.

Meanwhile, coastal areas will remain pleasantly cool and largely
under the influence of marine air. Morning clouds and afternoon
sun will largely be the rule for the rest of the upcoming week;
however, some areas of offshore flow around crescent city and
shelter cove should keep those areas a bit clearer for the mid to
late week period. Aad kr

Aviation Lifr stratus has dissipated on land for the most part
this afternoon, leavingVFR conditions at cec and acv. This stratus
remains just barely offshore though, and will quickly move back
inland in the late afternoon early evening. Lifr conditions are
expected most of the night again, complete with substantial
visibility restrictions due to fog. Clouds will likely clear again
late tomorrow morning or early in the afternoon.VFR conditions will
continue at uki. Brc

Marine A prolonged period of seasonably moderate strong
northerlies will persist through the week ahead. Although marginal
at this time, a small craft advisory is in effect across the outer
coastal waters of northwest california. Fresh wind gusts will
strengthen through Tuesday with gales possible by Wednesday. As
would be expected, seas will build and become steep, with heights
around 10 to 14 feet across the outer waters and 6 to 10 feet
nearshore. A small craft advisory may be needed across the nearshore
zones as conditions deteriorate with possible gales offshore mid to
late this week. Kml

Fire weather No major changes to the forecast package this
afternoon thus we will continue to headline isolated thunderstorms
over trinity county through the early evening. Do not expect as
prolific lightning as we had on Sunday, with just a few weaker
storms relegated mainly to areas around the trinity alps and
perhaps around trinity center.

The thunderstorm threat will be replaced by hot and dry weather
for the rest of the week. Temperatures of 95 to 110 and afternoon
rh in the teens can be expected for much of the interior, with
the hottest days coming on Tuesday and Wednesday. Fortunately, winds
will remain generally light and driven by terrain influences,
with onshore flow in the afternoons and offshore flow at night.
