SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0207 PM CDT Thu Sep 12 2024 Valid 131200Z - 141200Z ...NO CRITICAL AREAS... No changes to the ongoing forecast. ..Wendt.. 09/12/2024 .PREV DISCUSSION... /ISSUED 0136 AM CDT Thu Sep 12 2024/ ...Synopsis... As the upper trough and the associated cold front continue to the east, high pressure will quickly develop behind them over much of the Great Basin and Intermountain West. A much cooler and quiescent air mass will also develop, keeping winds relatively light with increasing relative humidity. Additionally, precipitation associated with the upper trough should moderate fuels across much of the West and Plains. A few stronger gusts may remain across parts of the southern High Plains and eastern WY. Pockets of lower RH may also remain in place temporarily before moisture increases later tonight. However, the expected duration and coverage of these locally stronger winds and drier conditions should be brief. With only modest overlap of dry and windy conditions atop dry fuels, fire-weather concerns are too localized for any highlights. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1224 PM CDT Thu Sep 12 2024 Valid 131200Z - 141200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN PARTS OF THE TN VALLEY TO THE FL PANHANDLE... ...SUMMARY... A couple brief tornadoes and locally damaging winds are possible across a part of the Southeast on Friday morning into the afternoon. ...Synopsis... The remnants of TC Francine will begin the day somewhere across eastern Arkansas and slowly drift east through the day while weakening. A belt of moderate mid-level flow will persist across the southern periphery of this remnant low. Farther west, a strong mid-level trough across the northern Rockies will weaken and move into the Canadian Prairies. A remnant surface cold front will traverse the Northern Plains through the day on Friday. ...Portions of the Southeast... A plume of tropical moisture will remain from the Florida Panhandle into central Tennessee on Friday. A mostly uncapped airmass is expected through the entire convective period. However, some greater instability is likely during the afternoon with some surface heating. However, given the limited inhibition, convective overturning is expected before more substantial instability can develop. Nonetheless, an extended period of 1000 to 1500 J/kg MLCAPE with 25 to 30 knots of effective shear will support some multicell clusters or occasional supercells. This may result in a brief tornado or two and the potential for locally damaging wind gusts, primarily during the afternoon/early evening on Friday. ...Northern Plains into the central Plains... A line of thunderstorms will likely develop along a cold front in North Dakota and South Dakota on Friday. However, instability will be relatively limited and elevated (500-800 J/kg MUCAPE). This weak instability combined with limited upper-level synoptic support, should mitigate any severe weather threat. Farther south, a few thunderstorms are possible in the Texas Panhandle and into western Oklahoma in the vicinity of a dryline/weak surface low where temperatures are expected to warm into the low 90s. While a few storms may develop, significant inhibition/dry air entrainment will likely keep the threat for more robust/severe convection muted. ..Bentley.. 09/12/2024 Read more
