SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0105 AM CST Mon Feb 19 2018 Valid 201200Z - 211200Z ...Synopsis... An upper-level trough over the West will weaken on Tuesday as a midlevel speed max ejects downstream across the Upper Mississippi Valley. At the surface, a low pressure system will lift northeast toward the Great Lakes with an associated cold front slowly advancing southeastward over the plains. ...Portions of Southern High Plains... Although the wind speeds aloft will be weakening compared to previous days, sufficient flow will likely yield sustained afternoon surface wind speeds approaching 20 mph through boundary layer mixing processes. Downslope westerly flow will also support warming/drying at the surface, resulting in afternoon RH values below 20% despite relatively cool temperatures across the region (generally at or below 60F). Overall, these meteorological conditions support elevated fire weather conditions given the dry fuels across the region. ..Jirak.. 02/19/2018 ...Please see www.spc.noaa.gov/fire for graphic product...
