Severe Storms

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1228 PM CDT Wed Mar 27 2024 Valid 281200Z - 291200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Thursday. ...Synopsis... A deep upper-level trough is forecast to move eastward across the eastern CONUS on Thursday, as another deep upper-level trough gradually moves eastward across the West. A surface cyclone is forecast to amplify and move northeastward just offshore of the Carolina coast, as a trailing cold front sweeps through the Florida Peninsula. While a favorable overlap of buoyancy and deep-layer shear will be in place across the FL Peninsula prior to the frontal passage, weakening large-scale ascent across the warm sector is currently expected to limit storm coverage and intensity. Otherwise, elevated convection may persist through the day across parts of the coastal Carolinas. Across parts of the Northwest, Great Basin, and northern Rockies, cold temperatures aloft associated with the upper-level trough may support weak convection capable of sporadic lightning flashes. Gusty winds may accompany convection across parts of eastern NV and western UT, but weak instability should limit the severe threat. ..Dean.. 03/27/2024 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1151 AM CDT Wed Mar 27 2024 Valid 271700Z - 281200Z ...NO CRITICAL AREAS... ...17z Update... No changes, see the previous discussion. ..Lyons.. 03/27/2024 .PREV DISCUSSION... /ISSUED 0149 AM CDT Wed Mar 27 2024/ ...Synopsis... Deep-layer northwesterly flow will overspread the southern High Plains as a mid-level trough traverses the Lower Mississippi Valley today. Dry downslope flow will develop across southeastern New Mexico into western Texas this afternoon, promoting conditions favorable for wildfire spread. By afternoon peak heating, 20-25 mph sustained west-northwesterly surface winds will overlap with 10-15 percent RH for at least a few hours. Given that these Critical meteorological surface conditions will overlap fuels that are at least marginally receptive to fire spread, "high-end" Elevated highlights have been maintained. ...Please see www.spc.noaa.gov/fire for graphic product...
