Synopsis
Cool and mostly cloudy weather can be expected Sunday into Monday
with a small chance of showers. A slow warming and drying trend
is expected for the rest of the week. By the week's end, look for
temperatures to surge well into the 70s.

Discussion
Tonight through Sunday night: a dirty northerly flow will remain
across the region through the weekend as mid and high level
moisture stream in from bc. This pattern will be slow to move as a
cutoff low slowly lifts out of the 4 corners region as a ridge of
high pressure spans the eastern pacific. A weak ripple in the flow
along with some surface based instability will be responsible for
light sprinkles across north idaho. The moisture looks to thin
briefly this overnight into Sunday, then as another ripple brushes
the northern mountains on Sunday afternoon into evening and added
a small chance of mountain showers. Temperatures will gradually
warm while winds remain light. Rfox.

Monday through Saturday... A weakening and stretching warm front
moves through on Monday bringing a thick band of mid level clouds
with it and a chance of sprinkles. Models show slightly deeper
moisture over the northern mountains into the idaho panhandle where
light rain of less than a tenth of an inch is possible. This will
provide a one day halt on our warming trend. An upper ridge
builds Tuesday through Friday bringing a warming trend with highs
Thursday and Friday warming into the mid to upper 70s with the
warmest spots in the lower 80s. Partly cloudy skies Tuesday will
give way to clear or mostly clear skies Wednesday through Friday.

The ridge flattens on Saturday as a mid level wave tracks north of
the area into british columbia. This should usher in slight
cooling but with continued dry conditions. Jw

Aviation
18z tafs: bands of mid level clouds will continue to spill in from
the north and bring a mid to high overcast at the TAF sites.

Isolated mountain showers are possible, although it should remain
dry at the TAF sites. Winds will remain light with a light east
wind, turning more northerly overnight. Rfox.

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.
