SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0113 AM CDT Fri Aug 11 2017 Valid 111200Z - 121200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF OREGON... ...Synopsis... A persistent Rex block over the Pacific Northwest will gradually break down today, as a relatively amplified trough approaches the coast. The residual mid/upper low at the base of the block will slowly lift northeast from northern California into Oregon. To its east, a weak/sheared impulse will remain quasi-stationary over Idaho and Wyoming, as a stronger wave drops south from Canada towards northern Montana. ...Pacific Northwest to the northern Rockies... The threat of new fire starts and erratic behavior will increase considerably once again today. The aforementioned low lifting into Oregon will focus convection from the eastern slopes of the Cascades to the Columbia River. While a few cores will produce wetting rainfall (with precipitable-water values around 0.7-0.9 inches), a combination of very dry fuels, scattered storm coverage, and dry/deep boundary-layer profiles supports a critical designation over Oregon. Elsewhere, other disturbances over the region will encourage thunderstorm development along higher terrain; however, storm coverage over sufficiently dry fuels should remain isolated to widely scattered at most. ..Picca.. 08/11/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
