NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
657 PM PST Tuesday Jan 27 2015 


Synopsis... 
areas of low clouds and fog will persist across portions of 
inland northwest as high pressure remains in place. A couple of 
weak storm systems will affect the area tonight and on through 
Thursday and bring a small chance of showers and cooler temperatures 
to the region. A ridge of high pressure will then rebound late in 
the week for drier weather and more fog, before breaking down next 
weekend. The next best threat of precipitation, including possible 
rain and snow, arrives on Sunday and beyond. 




&& 


Discussion... 
evening update sent to introduce areas of dense fog earlier in the 
evening and issue dense fog advisory. As the upper level ridge 
flattens tonight, we are seeing boundary layer winds switching 
around to the W/SW. Low clouds and fog that have been persistent 
over the lower Columbia Basin are now sloshing to the north and 
east. High clouds are masking the lower deck per satellite imagery 
but cams and observations suggest the low clouds are making it 
into the West Plains at this hour and will continue east into 
Spokane-cd'a overnight. The worst visibilities on a widespread 
basis remain over the Columbia Basin but trends this evening will 
be monitored closely and may need to expand advisories into Moses 
Lake area, Spokane, and perhaps the Palouse. 


Meanwhile, low clouds never cleared out of the northern valleys 
but did lift into a stratus deck for the time being with the 
exception of the us95 corridor. Visibilities of 1/4 mile have been 
rather consistent through the entire day at the Sandpoint and 
Bonners Ferry airports. We are not seeing widespread restrictions 
on Road levels for valleys of northern Washington so will leave 
them out of any advisories at this time. Models also hint a light 
north winds developing in the boundary layer as a weak midlevel wave 
passes through and this may bring enough downsloping to improve 
conditions somewhat overnight across northern Lincoln County. /Sb 


&& 


Aviation... 
00z tafs: a moist boundary layer trapped under an inversion with 
no weather systems strong enough to disturb the near surface layer 
will promote continued widespread IFR and LIFR conditions at or 
near all taf sites through the next 24 hours. The kgeg and kpuw 
and klws taf sites will experience a brief period of VFR 
conditions this evening while mid level cloud cover exists but 
after 06z this cloud cover will thin and allow radiational cooling 
to drop temperatures back to saturation and return fog and stratus 
to these sites. Moderate improvement is possible after 21z 
Wednesday but this is a low confidence forecast. Kmwh and keat in 
the deepest stagnant air will likely remain under IFR and LIFR 
conditions through the taf period. /Mjf
