NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
200 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. 
&& 


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...generally VFR clear through Thursday and beyond. Very diffuse 
surface thermal low situated from the north Oregon Coast Range to the 
S Oregon coast early this afternoon. This feature will drift back 
to the coastline tonight for very light offshore flow. May be 
some patchy fog tonight...primarily along the S Washington and north Oregon 
coast near the bays. 


Kpdx and approaches...VFR continues under dry stable air mass. 
Weishaar. 


&& 


Marine...rather tranquil marine conditions for the next few days. 
North wind to peak this evening...especially over the southern waters with 
gusts to 20 knots possible. Wind diminishes overnight tonight. 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 1 or 2 foot 
components through at least Friday...primarily from the west-northwest and south-southwest. 
Weishaar 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...none.
