SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0148 PM CDT Mon Jul 24 2017 Valid 251200Z - 261200Z No changes to the ongoing forecast are necessary. See below for more details. ..Picca.. 07/24/2017 .PREV DISCUSSION... /ISSUED 0314 AM CDT Mon Jul 24 2017/ ...Synopsis... Little change to the overall pattern is expected on Tuesday, as a slow-moving upper trough edges eastward into northern California and the Great Basin, while an upper ridge remains in place across the Southwest into portions of the southern/central Plains. At the surface, a trough will extend across much of the Plains south of a surface low near Hudson Bay, while high pressure settles into the Northeast. Generally weak surface features are expected across most of the West. ...OR/Northern CA eastward into southern MT... Scattered to numerous thunderstorms are again expected from OR/northern CA eastward into southern MT, with the slow-moving upper trough and embedded smaller-scale features remaining in the vicinity. Thermodynamic profiles are again expected to support a mix of wet and dry thunderstorms, with perhaps a slight tendency for greater rainfall potential given gradually increasing moisture with time and low-level cooling in some areas from repeated rounds of convection. Given uncertainties regarding the dryness of the thunderstorms, no critical area has been introduced for the threat at this time, though there will definitely be a threat of lightning-induced ignitions in areas where rainfall remains relatively light. ...Portions of eastern MT into the western Dakotas... Locally elevated conditions will be possible across portions of eastern MT into the western Dakotas within a dry post-frontal airmass. However, winds are not expected to be particularly strong and confidence in the concurrence of stronger winds and near-critical RH is too low for an elevated area at this time. ...Please see www.spc.noaa.gov/fire for graphic product...
