Synopsis
Temperatures will warm up the next couple of days with highs into
the 70s. Afternoon showers and thunderstorms are expected over
the cascades today and Thursday. By Friday a weather disturbance
will take up residence over western washington resulting in a good
chance of showers and afternoon thunderstorms for most of the
inland northwest. The disturbance will drop south of the area for
the holiday weekend with a chance of showers mainly for Saturday.

Discussion
Today through Thursday: a very large low is wrapped up over the
eastern dakotas, and moisture from that low is wrapping around
over montana and moving into the inland NW from the east. As this
moisture moves across the region, there could be some morning
sprinkles, mainly over the northern mountains. For the afternoon,
a few showers are expected over the cascades, but with the
easterly flow, these will mainly be found west of the passes.

On Thursday, the flow reverses back to a more normal westerly
direction. Instability over the cascades will cause afternoon
showers and a few thunderstorms to develop. A few of these storms
could have some decent rains. But in general, the atmosphere isn't
moist enough to cause any widespread flooding concerns in the
cascades on Thursday. Rj
Thursday night through Sunday... One closed low will move out of
the region on Thursday and another wave will drop south along the
front of a building ridge Friday. This wave will deepen and close
off as it tracks through b.C. And drops south along the crest of
the cascades. This low will continue to drop south into california
on Sunday. Instability will increase with the closed low, as mu
capes increase to 600-1000 j kg and moisture will increase to
over 200 percent of normal. This is a good set-up for widespread
showers starting late in the morning, with a good chance of
thunderstorms from mid afternoon through the early evening. With
abundant moisture and slow movement these storms will have the
potential for frequent lightning and heavy rain. We will have to
monitor burn scars along the east slopes of the cascades for any
flash flooding.

The low pulls away from the region on Saturday a little slower
than previously expected. Moisture wrapping around the exiting
low will keep a good chance of showers and thunderstorms for most
place outside of the columbia basin. By Sunday and Monday any
showers and thunderstorms will be focused near the cascades, the
blue mountains, the camas prairie, and possibly up the southern
part of the wa id palouse and over into shoshone county. One
bright spot in the forecast is that temperatures will increase a
few degrees each day with highs pushing into the 70s on Saturday
and into the mid 70s Sunday and Monday.

Tuesday and Wednesday a split flow will be over the region. We
can't rule out a stray wave moving south along the id mt border
and for now will go very low end on pops and we will see how the
end of the extended period plays out. We do expected the warmer
temperatures to continue. Tobin

Aviation
18z tafs: scatter to broken mid high clouds will continue to move
east over the region with TAF sites remainingVFR through the
period. Some brief clearing will start over the id panhandle and
propagate across extreme eastern wa later this evening. Gusty
northeast winds will continue today across eastern washington and
the northern panhandle but taper off later this evening through
the early morning. Aky

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.
