SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0115 PM CST Sun Dec 17 2023 Valid 181200Z - 191200Z ...NO CRITICAL AREAS... Fire-weather concerns appear negligible over the CONUS with weak winds, cooler temperatures and widespread precipitation. See the previous discussion. ..Lyons.. 12/17/2023 .PREV DISCUSSION... /ISSUED 0140 AM CST Sun Dec 17 2023/ ...Synopsis... Upper ridging will become established across the western and central CONUS as a mid-level trough amplifies over the Appalachians tomorrow/Monday. Surface high pressure and cooler air will continue to overspread the Rockies to East Coast areas, as appreciable precipitation accumulates over much of California. When also considering marginal fuel statuses across the U.S., the threat for significant wildfire-spread potential currently appears negligible. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1114 AM CST Sun Dec 17 2023 Valid 181200Z - 191200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM NEW JERSEY INTO SOUTHERN NEW ENGLAND... ...SUMMARY... A few damaging gusts are possible from the eastern shore of New Jersey into southern New England Monday morning. A few isolated lightning flashes are possible along the northern/central California coast. ...Northeast... A strong coastal low, oriented near NJ/DE Monday morning, will continue to modestly deepen as it lifts north/northeast through the period. Very strong deep-layer south/southeasterly flow ahead of the low and the associated shortwave trough will be oriented over the offshore waters and overspreading New England. While this will allow for 50s F dewpoints to spread across parts of southern New England, very moist and warm low/midlevel thermodynamic profiles are forecast. Widespread showers and cloud cover will preclude much heating, and low/midlevel lapse rates will remain poor. As a result, instability will remain meager. Nevertheless, strong ascent may be sufficient for a few lightning flashes and perhaps a stronger convective element or two moving onshore from the New Jersey to southern New England coast. With forecast winds in the 925-850 mb layer well over 50 kt, strong/damaging gusts are possible despite the overall poor thermodynamic environment. ...Northern/Central CA... A shortwave trough will move onshore during the afternoon and into the nighttime hours on Monday. Cool temperatures aloft and strong large-scale ascent may be sufficient for a few lightning flashes through the afternoon hours. ..Leitman.. 12/17/2023 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1038 AM CST Sun Dec 17 2023 Valid 171700Z - 181200Z ...NO CRITICAL AREAS... Cool temperature, weak winds and recent/ongoing precipitation over much of the CONUS will keep fire-weather concerns minimal through the forecast period. ..Lyons.. 12/17/2023 .PREV DISCUSSION... /ISSUED 0140 AM CST Sun Dec 17 2023/ ...Synopsis... A progressive upper pattern will characterize the synoptic environment over the CONUS today, with multiple mid-level troughs traversing the eastern U.S. as a third mid-level trough impinges on the California coastline. Regardless, surface high pressure and associated cooler air will surge southeast across the Rockies toward the Mississippi Valley, with wet conditions likely along the West Coast, mitigating major wildfire-spread concerns across the CONUS. ...Please see www.spc.noaa.gov/fire for graphic product...
