Area Forecast Discussion National Weather Service Spokane WA 511 AM PDT Thu Apr 2 2020

SYNOPSIS. Unsettled and cool weather will persist. Expect hit or miss showers over the Inland Northwest through the upcoming week. Occasional light accumulations of snow will occur during late night and early morning hours.

DISCUSSION. Today through Friday: Hate to sound like a broken record, but unsettled conditions are expected through Friday. The backedge of the trough has kept showers going through the night stretching from Deer Park and Spokane into the north Idaho Panhandle. These will exit through the early morning hours into western MT.

Showers will develop again this afternoon. The main area of concern is across the Cascade crest and the Palouse/Spokane area into the ID Panhandle. Westerly flow will largely skip the east slope valleys and Columbia Basin. There is some instability this afternoon, but given we are warmer at 500 mb and there were no lightning strikes in our forecast area yesterday, do not think there will be thunder today. Have lowered daytime highs a few degrees given how cool we were yesterday and several models showing little if any warming at 850 mb. Valley temps in the 40s is expected with maybe around 50 around Moses Lake. This is about 10 degrees below average for this time of the year.

Showers decrease this evening, but pick up again overnight across NE WA and N ID as another trough moves into the area from the north. Showers will become more widespread through the morning and afternoon hours as the stronger energy from the trough pushes into northern WA. Widespread mountain showers is expected across the region. About the only place to not see a shower would be the already dry Columbia Basin around Moses Lake and towards Wenatchee and Ritzville. Friday high temps could be a few degrees colder than today, especially across the north where they will see the bulk of the clouds and showers.

West to southwest winds will increase Friday and continue through the evening. Gusts 25-35 mph is possible stretching from Wenatchee across the Waterville Plateau and into the Columbia Basin, Palouse and Spokane area.

Showers will decrease Friday evening. Clouds will be on the decrease as well. Temperatures 8-10 degrees below average with valley temps in the 20s is expected. Patchy freezing fog is also possible across the northern valleys. /Nisbet

Saturday through Monday: As the Low slowly slide down the coast, it will push warm, saturated air into the region. As Saturday remains fairly quieter weather, the main push of precip chances for the region is expected Sunday. Precip will begin in the Southern Washington and push North through the day. It will be mainly mountain snow for the high terrains. The amount of wrap around moisture is not expected to be significant and impacts expected to very minor to none. Portions of the Basin will start as snow early Sunday morning and transition to mostly rain as daytime temperatures climb into the upper 40s and 50s. The chances of precip are expected to slowly drop off through Monday as the Low shifts further South and a ridge of high pressure begins to build into the Pacific Northwest. Overnight lows will be in the range upper 20s and 30s.

Tuesday and Wednesday: The region is expected to be under the influence of the ridge for the next couple of days. Lingering snow showers are possible for the mountains but a dry Northwest flow pattern is keeping the confidence pretty low of on impacts. Temperatures are expected to trend upward reaching into the upper 50s and low 60s for most locations. Mostly clear skies are expected to allow for decent diurnal temperature swings as overnight temps will dip near freezing and upper 20s. /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.
