NWS Forecaster Discussion




Area forecast discussion...update 
National Weather Service Pendleton or 
1040 am PDT Wednesday Jul 1 2015 


Updated for aviation discussion 


Short term...today through Friday...Ridge of high pressure over the 
region will intensify slightly through Friday. This will allow 
temperatures to climb enough to warrant another round of heat 
advisories for portions of the forecast area through Friday. Some 
convective moisture will try and lift northward into southern Oregon 
over the next couple of days. At best thinking that we will see some 
late day cumulus buildups over central Oregon but no thunderstorms. 


&& 


Aviation...18z tafs...VFR conditions to prevail over the next 24 
hours with clear skies...except a few scattered clouds at kbdn...krdm 
20z-04z. Surface winds will range 5-10 kts. Weber

&& 


Fire weather...fire weather watches have been posted for several 
zones in our forecast area...namely the areas across the Columbia 
Basin and surrounding valleys as well as the Columbia Deschutes 
plateau. The watch begins in the eastern Columbia River gorge on 
Thursday expanding to other areas on Friday. Decisions will be made 
on whether the watch for the Columbia River gorge will be upgraded 
to a warning on Thursday or cancel. At this time...it appears the 
winds will be relatively light on Thursday and may not meet the 
criteria for red flag. Will wait for the 18z runs and analyze 
closer before making this decision. It is the Holiday weekend...so 
even marginal wind and relative humidity threat will be considered for red flag.

Previous discussion... /issued 300 am PDT Wednesday Jul 1 2015/ 


Short term...today through Friday...high pressure aloft will 
amplify some today and become stronger with stronger subsidence of 
air aloft. This will result in a warming trend for the next few 
days. Expect high temperatures to top out between the upper 90s to 
lower 100s in the lower elevations and mostly 80s to lower 90s in 
the mountains. The hottest day will be on Friday with the warmest 
850 mb temperatures in eastern areas....and on Thursday along the 
Cascade east slopes. The ridge will weaken on Friday by afternoon 
with an increasing west to northwest flow aloft. This will bring in 
some cooler marine air through the passes and gaps in the Cascades 
onto the east slopes and adjacent valleys. Thus temperatures may 
actually be cooler along the Cascade east slopes...especially in 
southern and central Washington and the eastern Columbia River 
gorge. In eastern areas on Friday very hot temperatures will 
continue. Will adjust temperatures downward on Friday for the 
aforementioned areas along the Cascade east slopes and adjacent 
valleys. A heat advisory will remain in effect for the lower 
Washington Columbia Basin and then added to it will be north central 
and central Oregon at noon today. Then the northern Blue Mountain 
foothills and the Yakima and Kittitas valleys will be added to the 
heat advisory area at noon on Thursday. The heat advisory will then 
end for central and north central Oregon at 8 PM Thursday as cooler 
begins to filter through the gaps and passes of the Cascades. The 
remainder of the heat advisories will then end at 8 PM Friday. There 
are numerous fire weather watches in effect for portions of the fire 
weather district...mainly in areas where it will become breezy with 
very low humidities such as the lower Columbia Basin...central 
Oregon fire zones and through the eastern Columbia River gorge and 
the lower Columbia Basin. The fire weather watches are all expected 
to end at 8 PM Saturday...for now. 88 


Long term...Friday night through Tuesday...a weak and flat 
middle/upper level high pressure ridge will be over the region Friday 
night. The ridge axis will be oriented from the Great Basin to the 
west-northwest, which puts the forecast area in a west-northwest 
flow aloft resulting in downslope winds east of the Cascades for dry 
conditions Friday night. This pattern persists Saturday for dry 
conditions. The GFS hints at an influx of middle level moisture for a 
slight chance of afternoon/evening thunderstorms in central Oregon 
on Sunday through Tuesday. Polan
