Discussion Afternoon temperatures will be slightly cooler
today, due to the passage of a week cold front overnight.
Scattered valley rain and high mountain snow showers will linger
over the region through late morning.
A ridge of pressure is still expected to build over the northern
rockies Tuesday and Wednesday. This will allow for a warming and
drying trend to return to the region. Wednesday is expected to be
the warmest day of the week, with temperatures upwards of 10
degrees above normal. Thursday will be the start of a series of
weather disturbances moving into the inland pacific northwest.
This first system will bring cooler and wetter conditions, with
snowlevels lowering to around 5000 to 6000 feet.
A reinforcing shot of cold air will drop out of canada by late
Friday. This will begin to lower snow levels below 5000' and by|
Sunday morning, rain should transition to snow at valley level.
This is not an overly cold system compared to the previous two of
this season. That said, expect high temperatures from Friday
onward to average 10 to 15 degrees below normal. Overnight lows
during this timeframe will be at or slightly above seasonal
average due to cloud cover. It is still too early to talk
precipitation totals, but suffice it to say that the weekend will
Aviation Lingering valley rain and high mountain snow showers
will continue for the northern rockies through 14 1700z this
morning. Expect widespread mountain obscurations through much of
the day today. A ridge of high pressure will build over the region
this evening, and strengthen through the day Tuesday.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
