Organized thunderstorm potential is not expected the remainder of today or tonight. ...20z Update... The ongoing forecast remains on track and no changes have been made. For more details, see the previous discussion below. ..Leitman.. 02/01/2021 .PREV DISCUSSION... /ISSUED 0948 AM CST Mon Feb 01 2021/ ...Synopsis... The general thunder line was removed from the southeast Florida Peninsula as a surface cold front continues to usher convection away from the Florida Keys. As a high-amplitude mid-level trough and associated surface cyclone continue to advance eastward across the eastern U.S, cold surface temperatures and an eastward moving upper ridge across the central U.S will mitigate deep-moist convective development across the CONUS. A lightning flash or two may occur within the moist conveyer belt wrapping around the aforementioned surface cyclone along the New England Coastline through the remainder of the period. Similarly, a lightning flash cannot be completely ruled out across portions of the Pacific Northwest/northern California coastline this evening into tomorrow morning with the approach of an upper trough accompanied by scant buoyancy.
