SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0213 AM CDT Fri Aug 16 2024 Valid 181200Z - 191200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE MID-ATLANTIC AND CAROLINAS WEST-SOUTHWESTWARD INTO THE SOUTHEAST...AND ACROSS PARTS OF THE CENTRAL AND NORTHERN HIGH PLAINS... ...SUMMARY... A marginal severe threat is expected on Sunday from the Mid-Atlantic and Carolinas west-southwestward into much of the Southeast. A marginal severe threat will also be possible across parts of the central and northern High Plains. ...Mid-Atlantic/Carolinas/Southeast... An upper-level trough is forecast to move eastward into the southern and central Appalachians on Sunday. At the surface, an associated cold front is forecast to advance eastward into the Atlantic Coastal Plains, and southeastward into the southeastern states. Ahead of the front, surface dewpoints are expected to be in the 70s F, which will contribute to moderate instability across a broad area by afternoon. Isolated to scattered thunderstorms are expected to form near the boundary. Some convection may also develop southeastward into the moist airmass. Although the upper-level trough will likely provide some support for convective development, the area ahead of the trough from the Mid-Atlantic southeastward into the eastern Gulf Coast states is forecast to have marginal deep-layer shear for severe storms. A few isolated severe gusts will be possible near and after peak heating, mainly as low-level lapse rates become steep in the late afternoon. Further west into the lower Mississippi Valley, moderate instability is expected to develop by afternoon. Mid-level flow behind the trough will be northwesterly. This will result in stronger deep-layer shear, which should be sufficient for an isolated severe threat. The main uncertainty on Sunday in the lower Mississippi Valley is how instability will be distributed by afternoon. Some model solutions suggest that a cluster of storms will develop early in the day, which could negatively impact instability across parts of the region. Areas that can avoid this negative impact could have potential for severe wind gusts and hail during the afternoon. ...Central and Northern High Plains. An upper-level ridge is forecast to remain over the High Plains on Sunday. Beneath the ridge, a somewhat moist airmass should be in place with surface dewpoints mostly in the 50s and 60s F. As surface temperature warm on Sunday, isolated thunderstorm development will be possible across much of the central High Plains. Forecast soundings Sunday afternoon from eastern Colorado northward into western South Dakota have steep low-level lapse rates and moderate deep-layer shear. This suggest an isolated severe threat will be possible. However, subsidence associated with the ridge will negatively impact convective development, and any severe threat should remain marginal. ..Broyles.. 08/16/2024 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0132 AM CDT Fri Aug 16 2024 Valid 171200Z - 181200Z ...CRITICAL FIRE WEATHER AREA FOR SOUTHEASTERN OREGON AND NORTHERN NEVADA... ...CRITICAL FIRE WEATHER AREA FOR SOUTHWESTERN NEVADA AND PORTIONS OF CALIFORNIA... ...Synopsis... On Saturday, a mid-level shortwave trough is forecast to approach the northern California and Oregon coasts, with a fairly strong mid-level jet of 60-70 kts forecast to move northward from the San Francisco Bay area into southeastern Oregon. This trough and associated jet streak will bring critical fire-weather conditions across portions of southeastern Oregon and northern Nevada, as well as southwestern Nevada and the White/Inyo mountains of California. ...Dry/Windy... Two primary areas for critical fire-weather conditions are anticipated -- one over portions of northern Nevada and southern Oregon, and the other over southwestern Nevada and the White/Inyo mountain ranges of California. The strongest winds will likely be beneath the strongest flow of the mid-level jet streak and near the surface low in Oregon, forecast to be as high as 20-25 MPH with gusts up to 35 MPH possible. These winds will overlap with relative humidity values of 10-15% and ERC fuels near the 90th annual percentile. Some recent wetting rainfall has occurred over south-central Oregon, though modestly dry/windy conditions on Friday should result in at least some drying of fuels before Saturday. In southwestern Nevada and portions of the White/Inyo mountains in California, sustained winds of 20-25 MPH and relative humidity values of 10-15% will overspread fuels at or exceeding the 95th annual percentile, resulting in critical fire-weather conditions. Modifications to these areas may be needed with updated fuels and meteorological guidance. ..Halbert/Squitieri.. 08/16/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0103 AM CDT Fri Aug 16 2024 Valid 161200Z - 171200Z ...Synopsis... Broad, west-southwesterly mid-level flow will overspread portions of California and northern Nevada today, with a modest jet streak (with 40-45 kt winds) progressing east across the northern Great Basin. As this weak jet moves east, elevated fire-weather conditions are expected across portions of California and Nevada. ...Dry/Windy... South of this mid-level jet and north of a mid-level ridge centered over portions of Arizona and New Mexico, deep boundary layer mixing will result in dry and windy conditions across portions of California, Nevada, and Utah. Surface winds of 20-25 MPH and relative humidity values of 5-10% are expected, though will only overlap narrowly with a belt of receptive fuels across portions of Nevada and California. With winds and relative humidity being supportive of wildfire spread, but only modest fuel receptiveness, highlights have been limited to elevated conditions at this time. Recent wetting rainfall in eastern Nevada and western Utah will limit wildfire potential in these areas, though additional drying of fuels is expected given the dry/windy conditions. ...Dry Thunderstorms... The potential for some dry thunderstorms exists across portions of northern Wyoming and southeastern Montana. However, recent wetting rainfall and fuels guidance suggests there is minimal risk for wildfire spread and lightning-based ignitions at this time. ..Halbert/Squitieri.. 08/16/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0103 AM CDT Fri Aug 16 2024 Valid 161200Z - 171200Z ...Synopsis... Broad, west-southwesterly mid-level flow will overspread portions of California and northern Nevada today, with a modest jet streak (with 40-45 kt winds) progressing east across the northern Great Basin. As this weak jet moves east, elevated fire-weather conditions are expected across portions of California and Nevada. ...Dry/Windy... South of this mid-level jet and north of a mid-level ridge centered over portions of Arizona and New Mexico, deep boundary layer mixing will result in dry and windy conditions across portions of California, Nevada, and Utah. Surface winds of 20-25 MPH and relative humidity values of 5-10% are expected, though will only overlap narrowly with a belt of receptive fuels across portions of Nevada and California. With winds and relative humidity being supportive of wildfire spread, but only modest fuel receptiveness, highlights have been limited to elevated conditions at this time. Recent wetting rainfall in eastern Nevada and western Utah will limit wildfire potential in these areas, though additional drying of fuels is expected given the dry/windy conditions. ...Dry Thunderstorms... The potential for some dry thunderstorms exists across portions of northern Wyoming and southeastern Montana. However, recent wetting rainfall and fuels guidance suggests there is minimal risk for wildfire spread and lightning-based ignitions at this time. ..Halbert/Squitieri.. 08/16/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
