SPC Jul 10, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0226 AM CDT Sun Jul 10 2022 Valid 121200Z - 131200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHEAST... ...SUMMARY... Thunderstorms associated with a wind-damage threat are expected across parts of the Northeast on Tuesday. Marginally severe wind gusts may also occur in parts of the central Appalachians. ...Northeast.., An upper-level trough will move eastward through the eastern Great Lakes on Tuesday, as an associated 55 to 65 knot mid-level jet translates eastward across the Northeast. At the surface, a cold front is forecast to move eastward into the central and northern Appalachians. Ahead of the front, surface dewpoints in the mid to upper 60s F will likely contribute to a corridor of moderate instability by midday across parts of Pennsylvania and New York. Thunderstorms are expected to develop along the front during the afternoon, and move eastward toward the Atlantic Coastal Plains. GFS forecast soundings along and ahead of the front from southern Pennsylvania to eastern New York have 0-6 km shear in the 40 to 50 knot range. At low-levels, winds are veered to southwest. This combined with steep low-level lapse rates will likely support a wind-damage threat with multicells that organize into short line segments. Further southwest into eastern Kentucky and West Virginia, isolated thunderstorms will be possible during the afternoon along and ahead of the front. Although a few strong wind gusts will be possible, relatively weak deep-layer shear will keep thunderstorms unorganized. ..Broyles.. 07/10/2022 Read more CHECK UPDATE ZOOM GRAPHIC
