SYNOPSIS. Periods of drizzle and light rain will persist over the north Idaho Panhandle today and tonight. The next round of widespread precipitation is expected over the weekend. Light snow accumulations are expected in the mountains with rain in the valleys. Drier weather is expected Monday and Tuesday followed by chances for rain and snow Wednesday and Thursday.
Today and tonight: Bands of light precipitation over the central Idaho Panhandle early this morning are expected to slowly migrate north today and tonight. The focus for this rain and high mountain snow is the remnant of a stalled front. The models are in decent agreement that low level isentropic ascent in the vicinity of this washed out boundary will slowly lift toward the Canadian border this afternoon into tonight. A couple inches of snow will be possible above 4000 feet in the mountains around Sandpoint and Bonners Ferry by Friday morning. The lower elevations of far north Idaho and northeast Washington can expect periods of drizzle or light rain with temperatures in the mid 30s this morning rising toward 40 by the afternoon. A bank of fog and low clouds continues to reside around Tri Cities and Walla Walla. A weak push of north winds overnight cleared the fog and low clouds from Wenatchee and Ephrata. The fog briefly left Moses Lake, but appears to have returned (as of 2 AM). Portions of Columbia Basin that remain free of low clouds and fog today will have a good chance of climbing into the 40s this afternoon while areas that remain stuck in fog and low clouds will likely remain in the 30s.
Friday: A slow moving area of low pressure will approach the coast on Friday. Our region is expected to remain dry during the day with increasing chances for precipitation Friday night. We will be keeping a close eye on temperature trends in the Columbia Basin and along the East Slopes of the Cascades. At this time, it looks like the majority of the region will be above freezing as precipitation arrives Friday night into Saturday morning so we are not mentioning freezing rain. Aside from the potential of some light snow in the Methow Valley, we think most lowland precipitation Friday night into Saturday will be rain. /GKoch
Saturday and Saturday Night: Low pressure system will near the northern CA/southern OR border Saturday. As it does, pieces of energy will move up in the southwest flow and bring widespread valley rain and mountain snow to the region. Snow levels will be fairly high . starting out between 3500-4000ft and rising slightly through the day, and then lowering even further overnight. While most mountain passes will see snow, the only one where there could be more than an inch or two and possible minor impacts would be Lookout Pass.
Sunday through Wednesday: A ridge of high pressure will build along the west coast starting Sunday. Chance of precipitation as well as sky cover will decrease through the day. The ridge will slowly shift east through Tuesday keeping our forecast dry. There looks to be a weather disturbance that moves through the ridge in the Wed/Thur timeframe. There are still discrepancies as to how this will pan out, and wouldn't be surprised if in the end the ridge prevails. The blend has decreased its chance of precip with this system. The ensembles are showing higher heights by the end of the week, so the ridge will likely set back up.
Stagnant conditions will be possible starting Saturday and continuing into next week. Light winds with mixing heights below 2k ft is expected.
Temperatures will likely remain at or above average for this time of the year. Valley temps during the day in the mid 30s to lower 40s, and lows in the mid 20s to lower 30s. /Nisbet
AVIATION. 12Z TAFs: Various levels of low and mid level clouds across Washington and north Idaho make for a difficult set of TAFs. The Spokane and Coeur d'Alene areas experienced a bit of light rain overnight which wet the ground enough to generate areas of fog around the metro. The KGEG, KSFF, and KCOE forecast is low confidence of patchy morning fog with improving conditions through the day. The Moses Lake TAF is also difficult with a few of the web cams in the area showing transient fog. In general the fog bank that has plagued the Columbia Basin has eroded with a weak push of drier air from the north overnight, but this dry push is expected to decrease today which may promote fog expansion today and tonight. /GKoch

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.
