SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0244 PM CDT Sat Sep 06 2025 Valid 062000Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE NORTHERN MID-ATLANTIC REGION INTO NEW ENGLAND... ...SUMMARY... Scattered severe thunderstorms are possible from eastern Pennsylvania and New Jersey into New England this afternoon. The primary hazards will be strong to severe gusts capable of wind damage, isolated hail, and a tornado or two. ...20z Update... A severe convective line has evolved across the New England region earlier than anticipated by most guidance - even recent CAM solutions - and has a history of producing severe gusts and wind damage. Across New England ahead of the line, skies are gradually clearing with temperatures warming into the low 80s. This is supporting a gradual increase in MLCAPE that should maintain the squall line as it approaches the coast through early evening. Any appreciable tornado potential appears highest across this region based on recent radar trends that depict meridionally-oriented segments of the line that may support brief circulations. Severe risk probabilities have been adjusted to reflect these recent convective trends both ahead of and behind the line. Further to the southwest, more transient, but at times intense, convection continues to develop along the cold front from the Mid-Atlantic into the Southeast. Isolated instances of severe hail/wind will remain possible through the evening hours as thunderstorms develop within a buoyant, but modestly sheared environment. ..Moore.. 09/06/2025 .PREV DISCUSSION... /ISSUED 1103 AM CDT Sat Sep 06 2025/ ...The Mid Atlantic Region into New England... A large upper trough is present today over the Great Lakes region. At the surface, the effective low-level baroclinic zone extends from MD into eastern PA/NY and New England. To the east of the boundary, at least broken sunshine will help to steepen low-level lapse rates and destabilize the air mass. Thunderstorms have already begun to form along this zone, with intensification to scattered strong/severe storms by mid-afternoon. Mid-level lapse rates are not particularly steep, but southwesterly winds aloft are strong and deep layer shear will support rotating/bowing structures capable of damaging wind gusts and some hail. A tornado or two will also be possible. Model guidance is in agreement that the corridor of concern is rather narrow, with the main risk between about 19-23z. Refer to MD #2042 for further details.

A pronounced mid-level trough will progress inland from the West Coast while upper ridging continues over the Rockies tomorrow (Sunday). Upper support from the aforementioned trough will encourage locally dry and breezy conditions across western into northern parts of the Great Basin. Of somewhat greater concern is the potential for lightning strikes atop dry fuels over parts of the northern Rockies. By late afternoon, a dry boundary layer extending up to 700 mb will become established, which may encourage a wet/dry thunderstorm mix. Isolated dry thunderstorm highlights have been added where thunderstorms are expected to traverse the driest fuel beds. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
