Synopsis
Dry conditions with warmer temperatures are expected under a
ridge of high pressure through Tuesday. This will increase
mountain snowmelt and lead to rises on local rivers and streams
in the cascades and across the northern mountains of washington
and idaho. A strong cold front will bring breezy conditions
Tuesday evening and Wednesday along with much cooler temperatures.

Cooler and unsettled weather will likely persist until next
weekend.

Discussion
A few minor updates for high temperatures this afternoon to keep
all sites a degree or two warmer than yesterday. The warm
temperatures are eating away at the high elevation snowpack and we
are seeing the response on the river gauges. Many basins in the
cascades and which are fed from british columbia are rising
quicker than expected and river forecasts have been nudged upward.

The okanogan and stehekin rivers are now expected to achieve
minor flood stage by Tuesday morning and have been upgraded to
flood warnings. The kettle river remains in a watch due to some
uncertainty on timing and levels but will be monitored very
closely for changes.

Two other basins that are on my radar are the entiat and methow.

Expect these basins to reach bankfull but lower chances for
flooding at this time. The moyie and kootenai rivers in north
idaho will also be swollen from snowmelt yet remain forecast to
stay below flood stages. /sb
forecast focus outside hydrology will be on the winds for Tuesday
night and Wednesday as a strong cold front presses through
cooling temperatures 20 to 30 degrees from Tuesday to Wednesday.

If the front was coming through during peak heating... Wind
forecast would be a touch easier but the late evening/night timing
suggest the potential for valleys to decouple yet given its
strength, could uncouple for a few hours. More to come in the
afternoon update.

Aviation
18z tafs: a ridge of high pressure will remain over the region.

Some high cirrus at times, otherwise clear skies and light winds
will prevail through 18z tue. /sb

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.
