SPC 1930Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0214 PM CDT Wed Oct 23 2024 Valid 251200Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No severe thunderstorms are expected on Friday. ...Synopsis... Minimal thunderstorms will occur across the CONUS on Friday, with high pressure over much of the Plains and East. The exception will be from the Ozarks into the OH Valley where a narrow plume of low 60s F dewpoints will exist ahead of a weak cold front. Here, a few hundred J/kg of MUCAPE may develop during the afternoon, with weak lift possibly aiding isolated thunderstorm activity. The most favorable l…

SPC Day 2 Fire Weather Outlook Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0132 PM CDT Wed Oct 23 2024 Valid 241200Z - 251200Z Dry return flow ahead of an approaching cold front will result in elevated to locally critical fire weather conditions in portions of Oklahoma, Kansas, and the Texas Panhandle tomorrow. Latest high-resolution guidance indicates higher dewpoints will return to portions of eastern Oklahoma, eastern Kansas, and western Missouri than previously forecast, leading to a westward shift of the Elevated area. While RH will be around elevated criteria, temperatures will be well above normal in addition to the strong south…

SPC Day 2 Fire Weather Outlook Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1149 PM CDT Tue Oct 22 2024 Valid 241200Z - 251200Z ...Synopsis... Large-scale critical fire-weather conditions are currently not anticipated on Thursday. However, elevated-to-locally-critical fire-weather conditions may develop across portions of the Southern Plains. Here, a weak frontal boundary will weaken and dissipate in response to a developing lee cyclone. Strong, gusty southerly winds will take hold by the afternoon, with winds gusting around 30 mph at times. Additionally, residual circulations associated with the dissipating surface front will help dr…

Large-scale critical fire weather conditions are not anticipated on Wednesday. A surface high pressure will move across the central United States today in the wake of a departing mid-level shortwave. This will reinforce the dry airmass entrenched across the central U.S. However, slightly cooler temperatures, especially as you go farther north, will act to limit relative humidity from falling low enough to support critical fire weather conditions. Across the Northeast,…

Thunderstorm potential appears negligible today through tonight. ...Lower Great Lakes to northern New England... A broad mid/upper-level trough will progress across parts of southeast Canada and over the Great Lakes into the Northeast by Thursday morning.

SPC Day 3-8 Fire Weather Outlook Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0346 PM CDT Tue Oct 22 2024 Valid 241200Z - 301200Z Fire weather concerns will remain low in the extended. High pressure will build in across the CONUS through the mid to late week, with occasional shortwave progression across the northern periphery bringing a more zonal westerly flow pattern across the Rockies. This may bring potential for breezy conditions across portions of the northern and central Plains, primarily on D3 - Thursday. A period of Elevated to Critical winds and relative humidity will be possible in the Texas and Oklahoma Panhandles. Recent …

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0342 AM CDT Tue Oct 22 2024 Valid 251200Z - 301200Z ...DISCUSSION... Severe weather concerns will be minimal D4/Friday to D7/Monday as a mid-level trough amplifies across the Northeast and a strong surface high pressure center moves across the eastern CONUS in its wake. By late in the weekend to early next week, lee troughing will return to the Plains as a trough traverses the western CONUS. There is still considerable uncertainty regarding the timing and evolution of this trough, but in general, there is a consistent signal for a strong trough to eject out of the western CONUS in…

Large-scale critical fire weather conditions are not anticipated across the contiguous United States today. A surface cold front will move southward across the Plains today in the wake of a mid-level short-wave trough moving northeast toward the Great Lakes. Winds will increase and become gusty behind the front, however, a cooler airmass should allow relative humidity to remain above critical thresholds. ..Marsh.. 10/22/2024 ...Please see www.spc.noaa.gov/fire for graph…

Severe thunderstorms are not expected today through tonight. ...North-central States... Primary thunder potential should occur through about midday in association with a shortwave trough progressing from the Mid-MO Valley to the central Great Lakes. Despite dampening of this wave, sufficient forcing for ascent amid weak elevated buoyancy should yield at least isolated storms centered on the Mid-MS Valley. Modest cloud-bearing shear within the high-based/low-topped …
