Updated aviation and marine discussions
Discussion Current satellite imagery are showing some stratus
continuing just north of the umpqua divide and in the valley just
west of the cascade foothills. This stratus is continuing to
evaporate. Additionally, there are some higher clouds as well
that are moving to the southeast. Overall, a rather benign night
is expected. The forecast looks like it's in pretty good shape,
and no changes are needed. To learn more about the upcoming warm-
up, please read the previous discussion below. -schaaf

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.|
Marine... Updated 1030 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
Winds have diminished some below gales this evening but gusty north
winds and steep to very steep and hazardous seas are likely to
continue south of CAPE blanco into Friday.
Mainly small craft advisory conditions are expected Saturday into
Saturday night. After that, 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 keene
aviation... For the 23 06z tafs... A drier air mass is moving over the
region, and we expectVFR conditions at all terminals through
Friday. There is a chance that low clouds and or fog could form at
the coast and coastal valleys, but favored guidance supports clear
skies so expect koth to stayVFR overnight. Gusty north winds will
again impact the coast Friday afternoon. Keene
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
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

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
