Updated aviation discussion
Discussion 22 12z nam GFS ec in.

Partly cloudy skies linger this afternoon, mostly over the umpqua,
but the air mass is drying out rapidly. The weather will be more
summer like through next Wednesday night... Dry and hot.

An upper ridge is building over the area along with a thermal
trough offshore, and skies are clearing at this time. A strong
warming trend will affect all areas through Friday. By that time
highs will be 5-10 degrees above normal.

Short waves moving over the top of the ridge will keep it from
building any further this weekend, and this will put the brakes
on the warming trend. Saturday and Sunday highs will be about the
same as the Friday highs. A dry cold front will move through
Saturday. It won't bring any cooling, but it will bring gusty
winds to the east side Saturday afternoon and evening.

The ridge will build in more strongly next week, and the thermal
trough will move inland. That's when it will get really hot over
the area. Another strong warming trend will occur Monday into
Tuesday, and the Tuesday highs will be 10-15 degrees above normal.

The medford high will be near 100 degrees Monday and will exceed
it Tuesday. Wednesday will be similar to Tuesday with mostly clear
skies and hot temperatures.

At some point the ridge will break down and the possibility of
thunderstorms will enter the forecast with slightly cooler
temperatures. The latest GFS run shows that lis will remain
positive Wednesday afternoon and evening with pws of around 0.5
inches, which is too stable and dry. However, on Thursday
afternoon and evening there is a significant area of negative lis
east of the cascades and pws rise to near an inch. That is
sufficient for thunderstorm activity and thus will add a slight
chance of thunder at that time and location.

Aviation For the 23 00z tafs... Some clouds are lingering in the
umpqua basin this afternoon, remnants of the moisture that arrived
yesterday. All other locations areVFR, and a much drier air mass is
moving in, so we don't expect clouds to reform tonight at terminals.

The one possible exception is the umpqua basin near krbg, where
confidence is only moderate that we'll remainVFR through the night
there. Gusty north winds will again impact the coast Friday
afternoon. Keene

Marine Updated 130 pm pdt Thursday 22 august 2019... The thermal
trough has returned and will persist into early next week, although
there will be periods of weakening and strengthening over the next
several days.

Gale force winds and very steep and hazardous seas are likely to
develop south of CAPE blanco this afternoon and evening. Winds will
diminish very slightly Friday morning, but seas will remain steep
north of CAPE blanco and steep to very steep with gales south of
cape blanco through Friday evening.

Later Friday evening, the thermal trough is expected to weaken, so
gales will most likely end around that time. However, conditions
hazardous to smaller craft are likely to persist. Winds will
strengthen again Sunday with an area of gales possible again south
of CAPE blanco from Sunday afternoon through Monday evening. The
thermal trough is expected to push inland and weaken late Tuesday or
Wednesday, allowing conditions to improve for the latter half of
next week. -bpn

Fire weather Updated 200 pm pdt Thursday 22 august 2019... A
strong warming and drying trend will begin on Friday. The warmest
and driest conditions are likely on Tuesday, but improvement during
the remainder of the week will be barely noticeable.

While the passage of a weak, dry cold front on Saturday will not
bring any cooling, it will bring gusty westerly winds east of the
cascades with afternoon and evening speeds stronger than normal at
12 to 18 mph with gusts up to 25 mph.

Associated with the warming and drying trend will be night into
morning northeast winds of 5 to 15 mph over the coast range with
moderate mid slope and ridge humidity recoveries tonight through
Monday night.

The air mass will remain stable at least through Tuesday night, and
likely through Wednesday night. Model uncertainty increases beyond
day 5 with differences in the track of a closed low over the
pacific. -dw
