SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0154 PM CST Sun Nov 10 2024 Valid 102000Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for severe thunderstorms appears minimal through tonight. ...20Z Update... Other than minor changes to the general thunder area based on current observations, the previous forecast reasoning remains valid. ..Wendt.. 11/10/2024 .PREV DISCUSSION... /ISSUED 1039 AM CST Sun Nov 10 2024/ ...Discussion... An upper low now crossing the Upper Mississippi Valley is forecast to gradually devolve into an open wave, as it crosses the Upper Great Lakes region and shifts across the Ottawa River and St. Lawrence Valleys, and Lower Great Lakes through the end of the period. As this occurs, a surface cold front will similarly progress eastward across the Upper Great Lakes and Midwest region today, reaching the central and southern Appalachians by 11/12Z (Monday morning). Ahead of the front, a relatively moist boundary layer but weak lapse rates aloft will permit only weak warm-sector instability. While a more tropical low-level airmass will reside in the vicinity of the Lower Mississippi Valley, in part due to east-southeasterly advection associated with the presence of Tropical Storm Rafael sitting nearly stationary over the central Gulf, weak shear precludes appreciable severe potential. Farther north, stronger flow aloft will be offset by lower theta-e/weak CAPE as compared to areas farther south. As such, severe weather is not anticipated. Read more

SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0116 PM CST Sun Nov 10 2024 Valid 121200Z - 131200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN HIGH PLAINS... ...SUMMARY... Isolated severe hail will be possible in parts of the southern High Plains Tuesday evening. ...Southern High Plains... A mid-level trough will move into Rockies on Tuesday, as a broad belt of low-level flow strengthens across the Great Plains. At the surface, a cold front is forecast to advance eastward into the southern and central High Plains on Tuesday. Moisture advection ahead of the front will result in a north-to-south corridor of maximized low-level moisture across west Texas, where surface dewpoints are forecast to be in the 50s F and lower 60S F. MUCAPE is expected to increase into the 1000 to 1200 J/kg range along the moist axis by late afternoon, as mid-level lapse rates steepen due to the approach of the trough. Low-level convergence ahead of the front is forecast to become maximized early Tuesday evening, which should result in isolated to scattered thunderstorm development across the southern High Plains. NAM forecast soundings in the eastern Texas Panhandle at 03Z on Tuesday have effective shear near 40 knots, with 3-6 km lapse rates near 7 C/km. This may support isolated supercell development, with a potential for severe hail. The storms are expected to be elevated and marginal in nature, due to factors such as the late arrival of the trough, and relatively weak instability. ..Broyles.. 11/10/2024 Read more

A trough will move inland across the western US on Monday, bringing enhanced westerly flow aloft across the Great Basin in addition to potential for rain/snow showers. An increase in southwesterly surface winds will overlap dry conditions across portions of southern Nevada. Though relative-humidity reductions to around 15-20 percent are likely with sustained winds 10-15 mph (gusting higher), fuels in the region are largely unreceptive to fire spread.
