SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0229 AM CDT Mon Jun 24 2024 Valid 261200Z - 271200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF PA INTO NORTHERN NJ AND SOUTHEAST NY... ...SUMMARY... Scattered damaging winds are possible over parts of the Northeast and northern Mid Atlantic on Wednesday. ...Upper Ohio Valley into the Northeast/Mid Atlantic... A mid/upper-level shortwave trough is forecast to move from the upper Midwest toward the lower Great Lakes and Northeast on Wednesday. Rather moist low-level westerly flow will support potential for moderate diurnal destabilization from OH into parts of the Northeast and northern Mid Atlantic. Scattered thunderstorm development will be possible Wednesday afternoon along/ahead of a cold front across parts of OH/PA and southern NY, which will spread eastward into the evening. Strengthening flow in the 700-500 mb layer will support sufficient effective shear for storm organization, with potential for a few organized clusters and perhaps a couple of supercells. Damaging wind and perhaps isolated hail will be possible, along with some potential for a brief tornado if a supercell can be sustained. A Slight Risk has been added for parts of PA into southeast NY and northern NJ, where the most favorable overlap of instability, storm coverage, and strengthening low/midlevel flow is currently anticipated. Diurnal storm coverage becomes increasingly uncertain with southward extent, but at least an isolated severe threat could extend into parts of the Mid Atlantic during the late afternoon and evening. ...Lower Ohio Valley into the Ozarks vicinity... Uncertainty regarding storm potential and evolution is quite high from the lower Ohio Valley vicinity into the Ozarks. There is some potential for an MCS (or its remnant) to be ongoing at the start of the period. An outflow-influenced front will be draped somewhere across the region through the day, to the south of a reinforcing cold front that will move southward from the upper Midwest. Northwesterly mid/upper-level flow will be in place across the region, though the strength of the flow and any embedded shortwave troughs may also be influenced by antecedent convection and potential development of any MCVs. Some redevelopment of storms will be possible near the front and any remaining outflow boundaries. The northwesterly flow regime may provide sufficient effective shear for some storm organization, with one or more clusters possible with a threat of damaging wind and perhaps some hail. ...Southeast WY/northeast CO into central High Plains... Moist low-level southeasterly flow is expected on Wednesday from eastern CO/WY into the NE Panhandle, in the wake of a cold frontal passage. Moderate destabilization will be possible during the afternoon within this regime. While the region will initially be under the influence of an upper-level ridge over the southern Rockies, guidance suggests potential for a low-amplitude shortwave trough to crest the ridge from WY into western NY. This will support potential for at least isolated thunderstorm development. Midlevel flow may remain rather modest, but sufficient veering with height will support sufficient effective shear for storm organization, including some supercell potential with a threat of large hail and localized severe gusts. A strengthening nocturnal low-level jet could support some upscale growth, which could spread at least isolated severe-gust potential into parts of southwest NE and western KS. ..Dean.. 06/24/2024 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0137 AM CDT Mon Jun 24 2024 Valid 251200Z - 261200Z ...NO CRITICAL AREAS... ...Synopsis... An upper-level ridge will build into the Great Basin and extend into the Northwest on Tuesday. Overall, mid-level winds will be weaker across these areas than on previous days. There is some potential for subtle shortwave troughs within the flow to enhance winds in parts of northwest Nevada and southeast Oregon. An upper-level trough will approach the Northwest late in the period. The surface pressure pattern will be rather nebulous for much of the day. A surface low will deepen within the Columbia Basin vicinity, but this will primarily occur during the evening/overnight. At this time, only locally elevated fire weather conditions are expected from parts of northern Nevada into southeast Oregon and southern Idaho. A plume of mid-level moisture will push farther north and west as well. A weak shortwave trough is expected to promote thunderstorms along the Sierra Front in Nevada. The areas where confidence in storm coverage is highest will see an increase in PWAT values to near/over an inch. Drier storms could occur farther east in an area where mid-level moisture is less, but confidence in coverage is also much lower. ..Wendt.. 06/24/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Though surface winds will be slightly weaker than on Sunday, 15-20 mph winds can generally be expected given the lingering presence of the synoptic features described earlier. Stronger winds do appear probable in the Snake River Plain due to terrain effects and favorable orientation of the mid-level winds. RH of 15-20% will be common by the afternoon.

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0135 AM CDT Mon Jun 24 2024 Valid 241200Z - 251200Z ...Synopsis... An upper-level trough will continue eastward into the Northern Plains today. Upper-level winds across the Northwest into the northern Great Basin will remain modestly strong into the afternoon. Similarly, a modestly strong surface pressure gradient will remain across these areas before weakening overnight. ...OR/CA/NV into Snake River Plain... Though surface winds will be slightly weaker than on Sunday, 15-20 mph winds can generally be expected given the lingering presence of the synoptic features described earlier. Stronger winds do appear probable in the Snake River Plain due to terrain effects and favorable orientation of the mid-level winds. RH of 15-20% will be common by the afternoon. Elevated fire weather is expected with the greatest potential for locally critical conditions in the Snake River Plain. ..Wendt.. 06/24/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
