NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Friday Oct 31 2014 


Synopsis...a trough will linger over the Pacific northwest tonight. 
Saturday and Saturday night should be mostly dry as the trough 
shifts south of the region. Another front will approach the area on 
Sunday with rain developing. This will be the first in a series of 
weather systems that will bring rainy and breezy weather to the area 
through next week. 


&& 


Short term...the frontal band is weakening and shifting eastward with 
decreasing showers across western Washington late this afternoon. Satellite 
imagery indicates the trough is in the process of splitting so the 
shower coverage should decrease considerably through the evening. 
The exception could be around western Snohomish County northward if a 
convergence zone forms as advertised by the hrrr. This is highly 
uncertain given the lack of flow through the Strait but the hrrr 
does show converging winds at 925 mb. The 4km WRF-GFS/NAM-12 also 
show some localized quantitative precipitation forecast over the north interior early in the evening. 
Given that the northern branch of the upper trough is still offshore 
tonight and models show some spotty quantitative precipitation forecast...it seems reasonable to 
keep the chance probability of precipitation in place. 


The GFS/European model (ecmwf) indicate the upper trough will continue to split with 
almost all the energy to the north and S of western Washington. Forecast probability of precipitation were 
removed for most the interior Saturday and Saturday night. Some low 
chance probability of precipitation were maintained along the coast. There should be some 
partial sunshine during the day but the cooler air mass will keep 
highs limited to the low to middle 50s. 


Models are in good agreement that the next system will arrive 
Monday. Rain should reach the coast during the morning or near 
midday...then spread inland late in the day. Warm advection rain 
will persist Monday night through Tuesday over the entire area. 
Higher probability of precipitation are already in place during this period. 


Long term...global models agree on a wet pattern next week. The 
warm front moving through on Monday will be followed by a moist cold 
front. Some model runs including the 12z GFS show the main frontal 
band stalling over western Washington Monday night into Tuesday with locally 
heavy rain. See Hydro discussion below. 


Models diverge on the pattern by Wednesday. The European model (ecmwf) maintains the 
wet southwesterly flow pattern while the GFS is dry with more ridging. Other 
models like the Canadian show some break in precipitation but bring 
rain back into the area later in the day. Regardless...wet weather 
will resume Thursday and Friday as a stronger area of low pressure 
tracks near or to the north of western Washington. Both the Canadian/European model (ecmwf) show a 
deeper low closer to our area which bares watching as breezy or 
windy conditions are possible. Mercer 


&& 


Hydrology...the threat of river flooding has ended and the warning 
for the skokomish was dropped earlier today. A lull in precipitation 
is expected tonight through early Sunday so flooding is not 
expected. 


Rain will develop late Sunday and persist at times through the end 
of next week. The Monday through Tuesday period may have locally 
heavy rain...especially along S/SW facing mountain slopes. Some of 
the more flood prone rivers such as the Skokomish River will need to 
be watched in this pattern. 


In relation to the recent rain and expected upcoming wet 
pattern...the threat of landslides will also need to be monitored. 
The latest USGS 3/15 day precipitation threshold was surpassed but 24 
precipitation amounts were less than a couple inches at sea-tac 
which mitigates but does not eliminate the threat of landslides. 
More rain is anticipated next week so the landslide threat needs to 
be monitored as soils will approach near saturation. Mercer 


&& 


Aviation...moderate southwest flow aloft will weaken tonight and 
become light northwesterly Saturday afternoon as a weak upper trough 
moves through the area. The air mass is slightly unstable and moist 
with scattered showers. Drying will occur tonight and Saturday with 
partly sunny skies on Saturday. 


Ksea...VFR conditions this evening though a chance of a shower could 
briefly bring ceilings down to MVFR. There will probably be several 
hours of low end MVFR or IFR later tonight before improving to VFR 
Saturday afternoon. Light southerly wind becoming light northerly 
overnight. Chb 


&& 


Marine...pressure gradients are light today and there are no 
advisories in effect. The trough just offshore is forecast to be 
weak by the time it moves ashore tonight...so no advisories for that 
either. Weak high pressure will build Saturday. 


A series of stronger systems is likely for next week beginning 
Sunday. Small Craft Advisory winds are in the grids and forecasts 
for several periods centered around Sunday night and again 
Wednesday. Chb 


&& 


Sew watches/warnings/advisories... 


Washington...none. 
Pz...none.
