SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1200 AM CST Tue Dec 03 2024 Valid 041200Z - 051200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough will rapidly amplify while impinging on the East Coast tomorrow (Wednesday), resulting in a surface cold front sweeping across the eastern U.S. as high pressure builds across the Plains states. Modestly dry and breezy conditions may precede the surface cold front over the Southeast, while some dry downslope flow occurs over the central High Plains by afternoon peak heating. Given modestly receptive fuels in both locales, the marginally dry and breezy conditions suggest that wildfire-spread potential should remain localized. ..Squitieri.. 12/03/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1200 AM CST Tue Dec 03 2024 Valid 031200Z - 041200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough will amplify over the northern Mississippi Valley while another trough ejects into the Atlantic today. As a result, surface high pressure will overspread the Southeast as a surface lee trough and accompanying cold front sweeps across the Plains states. Cool and/or moist surface conditions will limit widespread significant wildfire growth potential over most locales. Dry downslope flow is possible across portions of the central and northern High Plains behind the cold front, with dry northwesterly flow also likely during the afternoon over the southern Florida Peninsula. Beyond the modest dry and breezy conditions, fuels across the central/northern High Plains and southern Florida Peninsula are marginally receptive to fire spread, suggesting localized wildfire-spread potential. ..Squitieri.. 12/03/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1131 PM CST Mon Dec 02 2024 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible along the south Texas Coast. Severe thunderstorms are not expected. ...South Texas... Weak mid-level height rises are forecast across deep south Texas much of the period. With weak short-wave ridging expected to dominate, it appears the LLJ will be one mechanism for weak convection through the period. In addition, a coastal boundary will also focus weak surface-based convection, where surface dew points are able to hold in the mid 60s. Even so, low-level shear is forecast to remain seasonally weak, despite the presence of low-level warm advection. Latest model guidance suggests elevated convection may evolve along the cool side of the boundary as parcels lifted near 850mb do yield some MUCAPE, possibly enough for lightning discharge within the strongest updrafts. Of more concern will be the surface-based buoyancy that evolves near the coastal boundary, as mid 60s surface dew points advance inland along the south TX coast. Forecast soundings exhibit around 500 J/kg SBCAPE within this environment, but shear will remain weak. Latest thinking is any convection that evolves should remain unorganized and updrafts are expected to be weak. ..Darrow/Squitieri.. 12/03/2024 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0628 PM CST Mon Dec 02 2024 Valid 030100Z - 031200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Threat for lightning is limited tonight. ...01z Update... Notable mid-level short-wave trough is digging southeast across the OH Valley early this evening. Seasonally cool, lower/mid- tropospheric profiles are resulting in steep lapse rates in the lowest 3-4km across much of the Great Lakes. While this is proving favorable for lake convection, lightning within the deeper, most robust updrafts has been limited. While a few strikes can not be ruled out with this activity, the probability for thunderstorms is less than 10% tonight, and for this reason probabilities have been lowered. ..Darrow.. 12/03/2024 Read more
