ZCZC SPCFWDDY2 ALL FNUS22 KWNS 220822 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0322 AM CDT Sat Jul 22 2017 Valid 231200Z - 241200Z ...Synopsis... On Sunday, an upper trough is expected to move eastward across portions of British Columbia and Alberta, while a slow-moving upper trough further to the south will approach the northern California coast. Some slight weakening of the upper ridge over the Great Basin and central/northern Rockies is possible in response to these features. At the surface, a low pressure area is expected to strengthen late in the period across the southern Canadian Prairie provinces, as a trailing cold front approaches portions of the northern High Plains by Monday morning. ...Southern OR/Northern CA into the Great Basin... Limited but sufficient monsoon moisture will support isolated to widely scattered thunderstorms on Sunday afternoon/evening from portions of northern CA/OR into the Great Basin. Relatively slow storm motions may allow for localized wetting rainfall, but thermodynamic profiles will support some dry thunderstorm activity, so an isolated dry-thunderstorm area has been included to cover this threat. The upper trough approaching northern CA has some potential to increase thunderstorm coverage across portions of this area, though this remains uncertain given some guidance indicating this system will stall off the coast. ..Dean.. 07/22/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
