Severe Storms

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CDT Sat Apr 19 2025 Valid 211200Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm potential appears low on Monday. ...Ohio Valley... An upper shortwave trough over the mid/upper MS Valley will lift east/northeast across the Great Lakes/OH Valley on Monday. A belt of enhanced mid/upper southwesterly flow will overspread much of the Midwest/Ohio Valley ahead of the upper trough. At the surface, low pressure over southern WI will lift northeast into Ontario/Quebec and a trailing cold front will move across the Ohio Valley. A narrow corridor of modest boundary layer moisture will overspread portions of KY/IL/OH/MI ahead of the front. Modest destabilization may allow for isolated diurnal thunderstorm development across the Ohio Valley. Poor lapse rates and weak instability should temper overall severe potential, but a few strong storms may produce gusty winds or small hail. ...Southeast TX to TN Valley... The southwest extent of the Ohio Valley cold front will stall across the region. Large-scale ascent will be nebulous across the region as the main upper shortwave trough continues to lift well to the northeast. Nevertheless, diurnal heating and low to mid 60s F dewpoints along the surface boundary will support isolated thunderstorm development. A few stronger storms could produce gusty winds or small hail, but overall severe potential appears limited given a lack of stronger forcing. ..Leitman.. 04/19/2025 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0214 AM CDT Sat Apr 19 2025 Valid 201200Z - 211200Z ...Synopsis... A mid-level trough will progress toward the OH Valley, encouraging the deepening of a surface cyclone as it tracks from the southern Plains to the Great Lakes tomorrow (Sunday). Another mid-level trough will eject into the Atlantic from New England, promoting deep-layer offshore flow across the region. Dry southeasterly surface flow is expected across western portions of the Florida Peninsula again Sunday afternoon. 10-15 mph sustained winds amid 25-40 percent RH will support Elevated fire conditions given dry fuels. Solidly Elevated meteorological conditions are also likely across coastal New England in association with the deep-layer offshore flow. However, recent appreciable rainfall accumulations will likely dampen fuels to the point where any wildfire-spread potential that manifests will likely be localized in nature. ..Squitieri.. 04/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
