Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1017 PM CST Thu Nov 08 2018 Valid 101200Z - 111200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Appreciable thunderstorm activity is not expected across the U.S. on Saturday; however, a few lightning strikes may be noted near Lakes Erie and Ontario. ...Discussion... Large-scale pattern will become increasingly hostile toward deep convection this weekend as dominant surface anticyclone settles into the MS Valley early, then shifts into the Middle Atlantic. While weak convection may evolve off the southern FL Peninsula it appears any showers that form over land will struggle to produce lighting. Farther north, very cold air will spread across the Great Lakes Saturday and surface-3km lapse rates are forecast to steepen significantly, especially across the lower Great Lakes. Convection will undoubtedly develop across Lake Erie and Lake Ontario and cloud heights may approach levels supportive of generating lightning. While a few strikes may be noted in the lee of these lakes, the greater threat will remain over the open water and coverage should remain too sparse to warrant 10% threat area at this time. ...MAXIMUM RISK BY HAZARD... Tornado: <2% - None Wind: <5% - None Hail: <5% - None ..Darrow.. 11/09/2018Read more
