area forecast discussion
national weather service medford or
857 pm pdt Tue jul 16 2019

Discussion An update to the forecast is not necessary this
evening. The previous discussion covers the main items of
interest. Low clouds are expected to thicken along the coast
overnight, then an occluding front will arrive at the coast early
Wednesday afternoon. It will weaken through Wednesday night into
early Thursday morning with light showers mainly north of our
area but a slight chance to chance will extend from coos county
into douglas county. Elsewhere in our area, clouds will be mainly
partly cloudy with temperatures remaining near normal.

The air mass will dry Thursday into Saturday morning with
temperatures still remaining near normal. At least a modest
warming trend is likely for Saturday into early next week. The
main uncertainty regards the extent to which instability and mid-
level moisture will increase Sunday through early next week, with
some potential for afternoon and evening thunderstorms as the
steering flow aloft backs from westerly to southwesterly. We will
be watching this closely. Based on the latest data, the increased
probability of thunderstorms early next week looks to be modest
though highest east of the cascades.

Aviation For the 17 00z tafs... .Along the coast and over the
coastal waters... Areas of MVFR ifr CIGS vsbys will persist into
Wednesday morning. The ifr conditions wil clear by late Wednesday
morning, but areas of MVFR CIGS will persist into Wednesday evening.

Over the remainder of the area,VFR conditions will prevail through
Wednesday evening.

Marine Updated 200 pm pdt Tuesday 16 july 2019... A thermal
trough will develop near the coast today, weaken Wednesday then
strengthen Thursday into Friday. Conditions will be hazardous to
small craft due to north winds and steep, choppy seas from gold
beach southward this afternoon into Wednesday morning. Advisory
conditions will likely return over a broader portion of the waters
Thursday afternoon into Friday evening, with gales and very steep
hazardous seas possible south of gold beach.

Prev discussion issued 242 pm pdt Tue jul 16 2019
discussion... Stable conditions will be present in northwest flow
through Saturday. The tail end of a weak front brings light
showers to much of the coast late Wednesday, moving inland
Wednesday night, bringing a slight chance of showers inland to
the cascades and down to the umpqua divide Thursday morning.

Morning cloud cover and northerly flow, except for the southern
coast where an offshore component will bring a weak chetco
effect, will keep temperature below normal through Friday.

Offshore flow spreads across the east side Friday night as a weak
ridge builds over the region and a thermal trough deepens and
spreads up the coast. This will bring temperatures to above normal
for the first time since near the beginning of july Saturday.

A turn to a more southerly flow starts to feed moisture into the
region with increased mid level moisture wrapping around the low
in the great basin Saturday evening. This will bring an area of
weak instability from the crater lake area and to the southeast
Sunday afternoon, and have added a slight chance of thunderstorms
to that area. However, confidence is low at this time. This area
of instability remains over the northern cascades early next week,
but do not have enough confidence to add any chance of
thunderstorms at this time.

Fire weather... Updated 200 pm pdt Tuesday 16 july 2019... Cool
conditions with breezy afternoon winds continue under the general
upper troughing regime in the pacific northwest. A thermal trough
will develop Thursday into Friday, and some northeast winds will
begin to affect the forecast area, especially in western siskiyou
county and the coast range in curry county. Temperatures will trend
higher to above normal values by the weekend, and enough moisture
could arrive by Sunday afternoon to bring a slight chance of
thunderstorms to areas east of the cascades. Keene

Mfr watches warnings advisories
Or... None.

Ca... None.

Pacific coastal waters... Small craft advisory until 11 am pdt
Wednesday for pzz356-376.

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.
