Area Forecast Discussion National Weather Service Spokane WA 355 PM PST Fri Jan 22 2021

SYNOPSIS. A cold overnight with lows in the teens and single digits. Saturday will start off quite chilly, but most areas will experience sunny skies and light winds for much of the day. Another chance for snow will arrive Sunday into Monday, this time with most locations seeing some light snow. Additional snow chances will come in around the middle of next week.

DISCUSSION. Tonight through Saturday: A quiet weather pattern will be in place over the region through the next 24 hours. The cool, dry northerly flow is expected to continue. Winds through the Northern Valleys are expected to weaken as the thermal gradient in those areas loosen. Overall the main impact will be in Southeast WA and Lower ID Panhandle. The area was stuck under a low level cloud deck that moved very little today and is expected to continue tonight and through tomorrow. The area can expect another round of fog through the tomorrow with little improvement. With overnight lows hovering around freezing, icy patches on untreated surface could be impact. Overnight lows are expected to be in the teens with single digits in the Northern Valleys. Highs on Saturday will be in the upper 20s and mid 30s.

Sunday: The ridge will breakdown as a Low drops in along the coast stretching a trough along the entire West Coast. The stretching pushes the bulk of the moisture and energy well South of the Inland Northwest. The region will see minor impacts form this system as it move West to East. It is expected to bring light snow starting late Sunday and lasting through Monday AM. Ensembles have lessened the snow amount as it passses.It is expected to bring one to two inches for the Inland Northwest. The snow could make slick conditions for the morning commute on Monday. Lows will be in the teens to low 20s. Highs will be in the 20s to low 30s. /JDC

Monday to Friday: Snow chances are expected to gradually decline through the day Monday into Monday evening with the highest chances lingering across the mountains of northern Idaho. Still, this system will certainly warrant watching over the next few days to monitor the potential for travel impacts during the Monday morning commute.

From Tuesday through the end of the week, many extended range models are indicating a persistently active pattern. Between Tuesday night and Thursday the next system is forecast to move in. Initially, the Cascades are favored before snow chances are progged to eastward into Wednesday. Currently, amounts look to be generally light, but it will still bring the next potential for impacts from snow. An unsettled pattern remains entrenched across the Inland Northwest through the end of the week, and finer details should become clearer in the coming days. /KD

AVIATION. 00Z TAFS: A thick cloud deck is continuing to bring LIFR/IFR to marginal VFR conditions for LWS-PUW. PUW-LWS expected to keep ceilings through the period with moderate improvement. PUW could be impacted by vis restrictions due to fog overnight. VFR conditions expected for EAT-MWH. Marginal VFR conditions possible for GEG-SFF-COE as the cloud deck shifts North overnight. Overnight fog and ceilings expected to impact Northern valleys. VFR conditions expected by mid morning as drier air continues to move into the region. /JDC

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.
