SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1254 AM CST Mon Dec 11 2023 Valid 121200Z - 131200Z ...NO CRITICAL AREAS... ...Synopsis... An upper-level cyclone will be positioned across parts of the Northeast with a cutoff low developing in the Great Basin in a quasi-Rex Block pattern. Surface high pressure will continue to be the predominant feature over much of the CONUS. Fire weather concerns will likely remain minimal on Tuesday for most areas. Offshore pressure gradients in southern California will increase very late Tuesday into Wednesday morning. However, RH recovery overnight and only marginal increases in the wind should keep fire weather concerns low through the end of the period. ..Wendt.. 12/11/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1127 PM CST Sun Dec 10 2023 Valid 111200Z - 121200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected in the U.S. today and tonight. ...DISCUSSION... At mid-levels, west-northwesterly flow will be present today across much of the continental United States, as a trough of low pressure moves eastward across the eastern U.S. At the surface, a large area of high pressure will move northeastward across the Southeast. This will suppress moisture return from the Gulf of Mexico, keeping a relatively dry and cool airmass in place over much of the nation. For this reason, thunderstorm development is not expected across the U.S. today and tonight. ..Broyles/Wendt.. 12/11/2023 Read more

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0654 PM CST Sun Dec 10 2023 Valid 110100Z - 111200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS FAR EASTERN NORTH CAROLINA... ...SUMMARY... A marginal tornado threat is expected to continue this evening near Cape Hatteras. Elsewhere across the continental United States, a severe threat is not expected. ...Far Eastern North Carolina... At the surface, a cold front is currently located in western North Carolina, in the vicinity of Greensboro and Charlotte. Thunderstorms are ongoing well to the east of the front across eastern North Carolina, where surface dewpoints are in the mid 60s F. In addition, the Morehead City WSR-88D VWP has 0-3 km storm-relative helicity near 400 m2/s2. This suggests that a marginal tornado threat should continue this evening, as storms move northeastward across the Outer Banks. The tornado potential will be minimal, and is expected to gradually diminish as the cold front approaches the coast later tonight. ..Broyles.. 12/11/2023 Read more
