SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0234 PM CDT Sat Mar 29 2025 Valid 301200Z - 311200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL AND SOUTHERN NEW MEXICO INTO FAR WEST TEXAS... The previous forecast (see below) remains generally on track. The primary change made to this outlook was to expand Critical probabilities into central and eastern New Mexico. Here, the latest guidance consensus shows 20-25 mph sustained westerly surface winds, overlapping with 10-15 percent RH and dry fuels, necessitating this northward Critical expansion. Dry, locally breezy conditions may also develop by afternoon peak heating across portions of the Mid Atlantic, though these conditions appear too brief to warrant Elevated highlights this outlook. ..Squitieri.. 03/29/2025 .PREV DISCUSSION... /ISSUED 0130 AM CDT Sat Mar 29 2025/ ...Synopsis... A belt of strong midlevel westerly flow will redevelop across the southern Rockies and adjacent High Plains during the afternoon, while a lee cyclone/trough persists over the southern High Plains. ...Southern New Mexico into the Texas Trans-Pecos... During the afternoon, deep boundary-layer mixing will extend into the base of the strong midlevel jet streak. This, coupled with a modest pressure gradient peripheral to the lee cyclone/trough, will favor 20-25 mph sustained westerly surface winds (with higher gusts) amid single-digit to lower teens RH. Given dry/receptive fuels across the area, critical fire-weather conditions are expected. ...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 0227 PM CDT Sat Mar 29 2025 Valid 311200Z - 011200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS A LARGE PART OF THE EASTERN U.S. INTO THE CENTRAL GULF COAST... ...SUMMARY... Strong/severe thunderstorms are forecast Monday from portions of the Northeast southwestward to the central Gulf Coast region. ...Synopsis... A surface low is forecast to intensify as it moves northeastward from the Lower Great Lakes into southeast Canada through the day Monday morning in tandem with a leading shortwave trough. A trailing cold front is expected to push east/southeast into the upper OH River Valley and lower MS Valley/Southeast early Monday morning as a second low-amplitude wave traverses the eastern CONUS. Thunderstorm potential will be focused along this front as it continues to push into New England, the Mid-Atlantic, and into the southeast states through the late afternoon and evening hours. ...Central Gulf States... Strong to severe thunderstorms may be ongoing by 12z Monday as a squall line forced along the cold front continues to push southeast across MS and AL. A combination of rich low-level moisture ahead of the line, diurnal heating, strong low to mid-level flow, and broad scale ascent ahead of the secondary upper wave should help maintain convective intensity into the afternoon hours. A corridor of damaging/severe winds, and potentially embedded tornadoes, appears probable from central MS into AL and western GA. ...Central Appalachians... Thunderstorm development along the front is expected by early to mid-afternoon from the upper OH Valley southward into the Mid-Atlantic region. Returning moisture through the Carolinas northward into eastern PA/western NY, combined with mid-level lapse rates around 7 C/km, should support sufficient buoyancy for deep convection, though buoyancy values should diminish with northward extent across the central Appalachians. Moderate flow within the lowest few kilometers should support a damaging wind threat as convection matures along the front across the upper OH Valley. Further south, stronger ascent ahead of the secondary upper wave should promote better storm organization, including the potential for semi-discrete cells and/or organized linear segments. Medium-range guidance suggests low-level winds will strengthen across the Mid-Atlantic region as a weak secondary low deepens through late afternoon in the lee of the Appalachians, which may support an enlargement of the 0-3 km hodograph and a locally higher tornado threat across the Carolinas into VA. ..Moore.. 03/29/2025 Read more

A surface low is forecast to intensify as it moves northeastward from the Lower Great Lakes into southeast Canada through the day Monday morning in tandem with a leading shortwave trough. A trailing cold front is expected to push east/southeast into the upper OH River Valley and lower MS Valley/Southeast early Monday morning as a second low-amplitude wave traverses the eastern CONUS. Thunderstorm potential will be focused along this front as it continues to push into New England, the Mid-Atlantic, and into the southeast states through the late afternoon and evening hours. ...Central Gulf States... Strong to severe thunderstorms may be ongoing by 12z Monday as a squall line forced along the cold front continues to push southeast across MS and AL. A combination of rich low-level moisture ahead of the line, diurnal heating, strong low to mid-level flow, and broad scale ascent ahead of the secondary upper wave should help maintain convective intensity into the afternoon hours. A corridor of damaging/severe winds, and potentially embedded tornadoes, appears probable from central MS into AL and western GA. ...Central Appalachians... Thunderstorm development along the front is expected by early to mid-afternoon from the upper OH Valley southward into the Mid-Atlantic region. Returning moisture through the Carolinas northward into eastern PA/western NY, combined with mid-level lapse rates around 7 C/km, should support sufficient buoyancy for deep convection, though buoyancy values should diminish with northward extent across the central Appalachians. Moderate flow within the lowest few kilometers should support a damaging wind threat as convection matures along the front across the upper OH Valley. Further south, stronger ascent ahead of the secondary upper wave should promote better storm organization, including the potential for semi-discrete cells and/or organized linear segments. Medium-range guidance suggests low-level winds will strengthen across the Mid-Atlantic region as a weak secondary low deepens through late afternoon in the lee of the Appalachians, which may support an enlargement of the 0-3 km hodograph and a locally higher tornado threat across the Carolinas into VA. ..Moore.. 03/29/2025 Read more
