Area Forecast Discussion National Weather Service Spokane WA 1041 AM PDT Wed Oct 21 2020

SYNOPSIS. A cold front will deliver the mountains a shot of early season snow today. A stronger and colder storm on Friday will likely bring widespread snow to the the Inland Northwest including many lowland locations. Temperatures over the weekend will be unseasonably cold and records will be possible Sunday and Monday. Next week is expected to be dry and stable with temperatures gradually rebounding close to average by mid to late week.

DISCUSSION.

Bands of elevated/forced rain and snow showers are slowly sagging southeast across Eastern Washington and North Idaho. The expectation is this activity will continue to weaken and/or move out of the area but be replaced with some surface based convection this afternoon that may linger a bit on into the early evening. In addition there could be and isolated weak shallow low topped thunderstorm or two mixed in near or over North Idaho. May tweak the forecast this morning to better address this activity. /Pelatti

AVIATION. 18Z TAFs: Bands of rain and snow showers will move southeast and either move out of the area or diminish in intensity this morning with some spottier and isolated rain showers this afternoon with an isolated afternoon weak shallow low topped thunderstorm or two mixed in near or over North Idaho thus spotty MVFR/IFR near the more intense activity. In addition breezy north winds will occur this afternoon and evening. By about 06Z Thursday some clearing should be underway allowing VFR conditions to prevail. /Pelatti

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.
