ZCZC SPCFWDDY2 ALL FNUS22 KWNS 160703 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0203 AM CDT Wed Aug 16 2017 Valid 171200Z - 181200Z ...Synopsis... As one mid/upper trough shifts eastward into the northern Plains and another trough approaches the British Columbia coast, a mid/upper ridge is expected to briefly build into portions of the Northwest on Thursday. In the wake of the leading trough, a cold front is expected to move through portions of the northern Rockies and northern High Plains, resulting in some increase in the fire weather threat. ...Montana into the far western Dakotas... A relatively dry and breezy post-frontal regime will result in a threat of elevated fire weather conditions across much of Montana east of the Continental Divide. Sustained winds of 15-20 mph are possible as RH values drop to near or below 20% during the afternoon. While locally critical conditions are possible, confidence in sustained winds exceeding 20 mph is too low for an upgrade at this time. Elevated conditions may spread into adjacent portions of Wyoming and the western Dakotas, depending on the timing of the frontal passage during the afternoon. ...Washington/Oregon/Idaho... Locally elevated conditions will be possible across portions of central/eastern WA/OR in the lee of the Cascades, and also across portions of the Snake River Valley in Idaho. RH may fall to near critical thresholds across these areas, though wind speeds are expected to remain relatively light outside of localized terrain-favored locations. ..Dean.. 08/16/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
