NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
907 PM PST Wednesday Mar 4 2015 


Synopsis...an upper level ridge of high pressure will remain through 
the weekend maintaining a dry and generally mild weather pattern. 
The upper ridge will weaken early next week and a front may bring 
rain to the region by Tuesday. 
&& 


Evening update...only minor changes to the forecast this evening. Based 
on the last couple of nights...decided to go with persistence and add 
some patchy fog to the southern Willamette Valley. Otherwise...expect 
another mainly clear and chilly night across the region. Similar to 
last night...expect many of the outlying valleys to drop into the 
middle to upper 20s...with most Interior Valley and coastal locations 
dropping down near freezing. This should again allow for areas of 
frost early Thursday morning. Thursday should again see temperatures rise well into 
the 50s. Added a few more high clouds to the forecast Thursday...which are 
associated with a low pressure system moving onshore over northern 
British Columbia and the Alaska Panhandle. Pyle 


Previous discussion issued 200 PM Wednesday Mar 4... 
short term...models maintain a strong ridge over the Pacific northwest 
through Sat for continued dry weather. Model consensus is for the 
weak north offshore flow to switch around to a S flow along the coast 
Friday. Flow however appears to remain weak...so the main threat for 
marine clouds and fog should be limited to near the coast Friday night 
into Sat morning. Inland expect skies to remain mostly clear through 
this time. 800 mb temperatures expected to creep up a couple of degrees each 
day resulting in gradually warming daytime temperatures through Sat for 
inland areas. By Sat afternoon surface winds expected to veer around to 
the north again...which should allow coastal areas to shake most of the 
marine clouds by the afternoon. 


Long term...European model (ecmwf) and Gem maintain a strong upper ridge through Monday 
with offshore flow. 12z GFS broke ranks with other models in digging 
a trough and cold front down from the northwest Monday...but a look through 
the GFS ensemble members indicated quite a bit of spread in the 
solutions. Given the better consistency in European model (ecmwf)/Gem solution prefer 
to continue closer to those models. After dry and mild weather sun 
and Monday...a system expected is expected to eject out of the east 
Pacific trough weakening the ridge and bringing chances for rain for 
Tuesday and Wednesday. 
&& 


Aviation...VFR through Thursday. There may be some patchy fog 
tonight and Thursday morning...primarily in the southern Willamette 
Valley near keug. 


Kpdx and approaches...VFR continues under dry stable air mass. 
/Mh 


&& 


Marine...rather tranquil marine conditions for the next few days. 
Winds have eased over the waters as diurnal effects have 
decreased. The thermally induced trough along the coast will 
weaken and shift inland Thursday. NAM model still suggesting a wind 
reversal over the waters late Thursday and Thursday night. Weak surface 
gradients over the waters during the weekend and first part of 
next week. Significant model differences early to middle next week. 
Have leaned toward the European model (ecmwf) for the end of the extended period. 


Seas holding in the 3 to 5 foot range for the next few days. 
Spectral analysis suggests there will be multiple 2 or 3 foot 
components through at least Friday...primarily from the west-northwest and south-southwest.
