ZCZC SPCFWDDY2 ALL FNUS22 KWNS 081646 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1046 AM CST Thu Feb 08 2018 Valid 091200Z - 101200Z Morning guidance suggests elevated fire-weather conditions may extend farther east into portions of northwest Texas. Here, a belt of westerly winds up to 15 mph, with some stronger gusts, will support downslope warming/drying. The result will be relative-humidity values falling into the teens and low twenties. This combination of wind and relative humidity, along with long-term drought, will support a broader area of elevated fire-weather conditions than previously forecast. ..Marsh.. 02/08/2018 .PREV DISCUSSION... /ISSUED 1152 PM CST Wed Feb 07 2018/ ...Synopsis... Quasi-zonal flow should transition to broadly cyclonic over the CONUS on Day 2/Friday as a shortwave trough moves southeastward over the Pacific Northwest. Mid-level westerly flow should gradually strengthen over the southern High Plains by Friday evening. At the surface, an area of low pressure is forecast to deepen over the central/southern High Plains through the period, with lee troughing extending southward from this low across eastern NM. ...Portions of the Southern High Plains... In response to a strengthening surface pressure gradient and modestly increasing mid-level westerly winds, strong/gusty winds around 15-20 mph appear likely across part of east-central NM Friday afternoon. Downslope warming/drying at low levels should reduce RH values into generally the 10-20% range for a few hours through peak heating. Coupled with dry/dormant fuels, these expected meteorological conditions should support an elevated designation across portions of east-central NM. ...Please see www.spc.noaa.gov/fire for graphic product...
