Discussion 22 12z NAM in. 22 12z GFS in through 18hr.

Partly cloudy skies linger this morning in the wake of the front
that moved through yesterday. The upper trough supporting the
front has also moved off to the east, and precipitation has ended
over the area.

The precipitation was unusually widespread and heavy for an august
system with wetting rains reported across southern oregon... Even
in lake county. The heaviest reported rain total was 0.99 inches
at the silver butte raws in douglas county. Many locations in
oregon reported totals exceeding 0.50 inches, with lighter amounts
in northern california.

That will be it for a while, as the next week looks dry with hot
temperatures returning to inland locations.

An upper ridge will build in today along with a thermal trough
offshore, and skies will clear just about everywhere over the
land areas. 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 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.

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 models are hinting that this may occur as early
as next Thursday. There is not enough confidence in the forecast
to add any convection just yet, but it will be something to
monitor closely.

Aviation For the 22 12z tafs... A mix of lifr and ifr CIGS are
spread across most of southern oregon and portions of northern
california this morning. Along the coast, CIGS have cleared out
for the most part with some MVFR CIGS still lingering off the coast
over the waters. Look forVFR conditions over all areas during the
late morning through tonight as some very dry air moves into the area.

Marine Updated 830 am pdt Thursday 22 august 2019... North winds
have returned to the waters this morning as a thermal trough
strengthens inland. The thermal trough will then persist in the area
into early next week.

Winds will rapidly increase today, reaching gale force with very
steep hazardous seas south of CAPE blanco this afternoon. Winds will
diminish very slightly on 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 won't be as strong, so
gales will most likely end. 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. -dw

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.
