337 ACUS01 KWNS 261931 SWODY1 SPC AC 261930 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0130 PM CST Tue Nov 26 2024 Valid 262000Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the continental U.S. today and tonight. ...20z Update... The previous forecast remains on track with no changes needed. Occasional lightning flashes are possible late this evening across the inter-mountain West as an upper trough shifts east, but coverage is expected to remain very isolated (sub-10% coverage). Forecast thoughts regarding shallow frontal convection across the Southeast remain valid (see previous discussion below). ..Moore.. 11/26/2024 .PREV DISCUSSION... /ISSUED 1009 AM CST Tue Nov 26 2024/ ...Synopsis... Fast zonal winds aloft are present across much of the CONUS today, with a strong cold front moving eastward across the eastern states and eventually offshore today. Weak CAPE and poor lapse rates are expected to preclude organized thunderstorm development along the front until it moves offshore and over the Gulf Stream waters. $$
