Area Forecast Discussion National Weather Service Spokane WA 332 AM PST Wed Feb 19 2020

SYNOPSIS. The remainder of the week will be dry with near average temperatures. We can expect a good deal of sunshine and relatively light winds through Friday. The arrival of a storm system over the weekend is expected to bring increasing chances for rain and snow, and gusty winds Sunday into Monday.

DISCUSSION.

Today through Thursday: Ridge of high pressure influences Eastern Washington and North Idaho through this period. The result will be dry weather with some low clouds and fog in a few lowland and valley locations during the overnight and morning hours. At the surface the thermal ridge axis will remain west of the Cascade crest and thus influence low level winds to make them prevail generally from the East. Sunshine during the day with efficient radiational cooling during the nighttime hours will allow for high temperatures near normal with overnight lows more on the cool side of what would be considered normal. /Pelatti



AVIATION. 12Z TAFs: High pressure will keep VFR conditions at TAF sites for the next 24 hours. /Pelatti

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.

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 numerous 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.
