ZCZC SPCFWDDY2 ALL FNUS22 KWNS 161830 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1230 PM CST Tue Jan 16 2018 Valid 171200Z - 181200Z ...NO CRITICAL AREAS... Locally elevated fire weather conditions may occur Wednesday afternoon across parts of the FL Panhandle. High temperatures across this region are expected to remain cool, generally in the mid to upper 40s, owing to the passage of a cold front on Day 1/Tuesday. Still, a very dry post-frontal airmass coupled with modest diurnal heating may allow RH values to fall into the 25-30% range for a couple of hours Wednesday afternoon. Northwesterly surface winds should modestly increase to around 10-15 mph in combination with the marginally lowered RH values to support locally elevated fire weather conditions where fuels are dry. However, there is some uncertainty regarding light post-frontal precipitation potential across parts of the FL Panhandle late Day 1/Tuesday into early Day 2/Wednesday. Given this uncertainty, and the marginal forecast winds/lowered RH values, will defer possible introduction of an elevated area to a future update. ..Gleason.. 01/16/2018 .PREV DISCUSSION... /ISSUED 0124 AM CST Tue Jan 16 2018/ ...Synopsis... The highly amplified deep-layer trough is forecast to exit the eastern half of the CONUS throughout the period. To the west, another shortwave trough will enter the Pacific Northwest, with a ridge developing over the northern Rockies. At the surface, high pressure will build into the upper Great Basin, resulting in a surface pressure gradient that may allow offshore winds of 10-20 mph and lowered RH to develop briefly across southern CA late Wednesday night into early Thursday morning. However, recent heavy rainfall in this region has rendered fuels generally unreceptive to large-fire potential, and therefore no areas have been highlighted. ...Please see www.spc.noaa.gov/fire for graphic product...
