NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
235 am PDT Sat Aug 1 2015 


Synopsis...an upper level ridge of high pressure over the region 
will continue to bring warm temperatures to the inland areas through 
the weekend. The ridge of high pressure will move east of the 
region early next week and bring a gradual cooling trend. Monsoonal 
moisture from the south will bring a slight chance of a shower or 
thunderstorm to the Oregon Cascades late in the weekend and early 
next week. 
&& 


Short term...fog channel on satelite pictures showed a narrow band 
of stratus along the coast. Most of the clouds appeared to be just 
offshore along the Oregon coast...but inland a little on the S Washington 
coast. With a northerly flow in the boundary layer it may be 
difficult to get clouds or fog to push much inland...so expect 
clouds this morning on the coast mainly to just be patchy, 


Water vapor picture showed the upper ridge axis remained across far 
southern Oregon. Models continue to agree that the strong ridge will 
slowly shift north over the region today and finally shift east tonight and 
sun. With only minor changes seen in 1000-500 mb thickness values 
and 800 mb temperatures...highs today are likely to cool only marginally with a 
slightly improved onshore flow. This results in another very hot day 
for much of the forecast area...and a continuation of heat 
advisories and warnings. As the ridge shifts north later today and 
tonight the upper level flow will open up to the S. Models agree in 
streaming some high level moisture north in this flow tonight through 
Sun night. Some instability is seen in model soundings aloft...but 
it is not clear if there is sufficient dynamics to overcome a middle 
level warm layer. For now will keep a slight chance for 
thunderstorms over mainly the Oregon Cascades from this afternoon 
through Sun night. 


As the ridge shifts east sun and Monday...upper heights begin to drop off 
and low level onshore flow strengthens. This will bring about 
gradual cooling for sun and Monday. 800 mb temperatures around 19 degree c suggest 
highs down around 90 in the inland valleys by Monday. 


&& 


Long term...no changes. Previous discussion follows...a few model 
discrepancies start off the extended period. Both the 12z GFS and 
European model (ecmwf) show an upper level trough approaching the region from the 
northwest late Monday...but the European model (ecmwf) deepens the low by early 
Tuesday whereas the GFS just skims the top of the Pacific northwest 
early next week. The models then have timing issues on bringing a 
trough over the area late next week. Overall...we will see a general 
cooling trend through the week with high temperatures returning back 
to normal. Could see a threat for Cascade thunderstorms Monday 
evening and again Tuesday afternoon and evening. We may also see some 
showers clip the SW Washington and northwest Oregon coast by Wednesday and 
Thursday if the European model (ecmwf) solution comes to fruition. /27 


&& 


Aviation...VFR conditions continue today and tonight for the 
inland terminals. Gusty north winds will return this afternoon and 
evening. Narrow band of marine stratus remains primarily just 
offshore along much of the Washington and Oregon coasts and is 
continuing to slowly expand. This is a rather shallow layer...with 
latest satellite derived cloud top estimates sitting around 1500 
feet. Increasingly north winds after 18z increase chances for stratus to 
push away from coast. 


Kpdx and approaches...VFR conditions with weaker northerly winds 
overnight starting to increase for the afternoon hours around 17z 
Saturday. Cullen 


&& 


Marine...gusty north winds persist this weekend with high pressure 
offshore and thermal trough inland. Overall wave component 
dominated by north to northwest wind wave and fresh swell...and these are 
responsible for steep seas especially over the central Oregon 
waters. Little change in the pattern for Saturday and much of 
Sunday...namely choppy conditions and gusty winds between north and 
northwest...particularly in the afternoon and evening hours each day. No 
changes to the advisories this evening as these look to remain on 
track. Cullen
