SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0141 PM CST Sat Nov 23 2024 Valid 241200Z - 251200Z ...NO CRITICAL AREAS... ...20z Update... No changes. Despite the prevalence of strong winds and low humidity for several hours across the southern High Plains, overlap with dry fuels is minimal. See the previous discussion. ..Lyons.. 11/23/2024 .PREV DISCUSSION... /ISSUED 1157 PM CST Fri Nov 22 2024/ ...Synopsis... A mid-level trough will eject into the Plains states, resulting in the eastward progression of a surface low from the central Plains into the MS Valley. An eastward-sweeping surface cold front will accompany the surface low, with dry downslope flow expected across the southern High Plains. Elevated fire weather conditions are likely across far southeastern New Mexico into Far West Texas by afternoon peak heating. However, fire weather highlights have been withheld this outlook given the marginal receptiveness of fuels. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0120 PM CST Sat Nov 23 2024 Valid 251200Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible late Monday into Monday night from the Sabine Valley into parts of the Mid-South. ...Synopsis... A mid/upper-level low initially over parts of SK/MB is forecast to move southeastward toward the upper Great Lakes on Monday, as a leading shortwave trough ejects eastward across parts of the Midwest and Ohio Valley. A surface low is generally forecast to deepen and move northeastward from the mid MS Valley region towards the lower Great Lakes, though guidance continues to vary somewhat regarding the timing and strength of this low. A trailing cold front will move across parts of the lower Great Lakes, OH/TN Valleys, and lower/mid MS Valleys. Across the West, a weakening mid/upper-level low is forecast to gradually move southeastward towards parts of the Pacific Northwest coast. ...Sabine Valley into the lower MS Valley/Mid-South/TN Valley... Low-level moisture return will continue on Monday along/ahead of the front, with 60s F dewpoints spreading from east TX into parts of the Mid-South, and lower/mid 50s F dewpoints potentially reaching into parts of the Ohio Valley. Isolated thunderstorms may develop (mainly later in the forecast period) within the richer moisture along/ahead of the front from the Sabine Valley into the Mid-South/TN Valley. Deep-layer shear will become increasingly favorable with time, and a strong storm or two cannot be ruled out, but most current guidance suggests that weak buoyancy/lapse rates will tend to limit storm organization and intensity. ...Ohio Valley... Guidance generally suggests that low-level moistening will be insufficient to support deep convection with northward extent along the front into the Ohio Valley, resulting in low thunderstorm potential. The most aggressive guidance (with respect to the strength of the surface low and frontal convergence) does depict some potential for weak low-topped convection with localized gusty winds spreading eastward with the front from late afternoon into the evening. ..Dean.. 11/23/2024 Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1058 AM CST Sat Nov 23 2024 Valid 241200Z - 251200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Sunday. ...Synopsis... On Sunday, a deep-layer cyclone is forecast to remain offshore of the Pacific Northwest, with multiple midlevel shortwave troughs potentially moving inland along the south/east periphery of the cyclone. Farther east, a strong mid/upper-level jet is expected to shift eastward over the south-central Plains, resulting in amplification of a shortwave trough moving across the Canadian Prairies and northern Great Plains. A surface low initially located over KS is forecast to move northeastward through the period, as a trailing cold front advances southward across the Plains. Low-level moisture return is expected to commence across south TX into the ArkLaTex, though this early-stage moisture appears insufficient to support deep convection across the region through the end of the period. Farther west, buoyancy may become sufficient to support weak convection with sporadic lightning flashes near the OR/northern CA coast, as multiple waves of precipitation move onshore in association with the offshore mid/upper-level low/trough. Weak convection could also accompany the midlevel shortwave trough moving from the northern Rockies into the north-central Plains, but instability currently appears too weak to support lightning potential with this activity. ..Dean.. 11/23/2024 Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1056 AM CST Sat Nov 23 2024 Valid 231700Z - 241200Z ...NO CRITICAL AREAS... ...17z Update... No changes were made to the prior forecast. A few hours of locally elevated fire-weather conditions are possible in the lee of the Laramie Range and across the interior highlands of southeastern WY. Strong zonal mid-level flow and downslope pressure gradients will support several hours of very strong winds and mountain wave activity. While RH and winds are likely to exceed critical criteria, area fuels vary substantially. Short-hour and frost-cured fuels at lower elevations could support some risk given the little recent precipitation. However, the broader lack of receptive fuels suggests any fire-weather threat that does develop will be isolated. ..Lyons.. 11/23/2024 .PREV DISCUSSION... /ISSUED 1157 PM CST Fri Nov 22 2024/ ...Synopsis... A mid-level ridge will progress across the central CONUS as a mid-level trough overspreads the Interior West today. Surface high pressure will prevail across the Southeast, accompanied by a weak surface wind field. Surface lee troughing is expected in the Plains, where low-level moisture return will also occur. Appreciable precipitation accumulations are also likely over the northwestern CONUS.
