SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0222 AM CDT Tue May 21 2024 Valid 221200Z - 231200Z ...Synopsis... A broad upper trough will encompass the central and western CONUS Wednesday. The strongest mid-level flow is expected to extend from the Southern Plains through the Upper Midwest and Great Lakes regions, and across the Pacific Northwest near the base of mid-level cyclone. A deeply mixed air mass will remain present over the Desert Southwest, while a cold front dives southward into portions of the Southern and High Plains. Further west across portions of NM and AZ, sustained westerly surface winds near 15 mph are expected where increasingly receptive fuels and single-digit RH will be present. Localized wind speeds may briefly approach or exceed 20 mph across southern NM Wednesday afternoon, but the probability of this occurring for more than 3 hours across a broad region is too low to introduce a Critical area at this time. ..Barnes.. 05/21/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 0864 CONCERNING TORNADO WATCH 273... FOR SOUTHWESTERN NEBRASKA INTO NORTHWESTERN KANSAS
Mesoscale Discussion 0864 NWS Storm Prediction Center Norman OK 0129 AM CDT Tue May 21 2024 Areas affected...southwestern Nebraska into northwestern Kansas Concerning...Tornado Watch 273... Valid 210629Z - 210730Z The severe weather threat for Tornado Watch 273 continues. SUMMARY...A cluster of intense storms continues moving eastward across southwestern Nebraska and adjacent northwestern Kansas. All-hazards severe risk is evident. DISCUSSION...A well-organized, broadly rotating storm is currently observed crossing the Hayes/Hitchcock County vicinity in Nebraska, with trailing storms extending southwestward to Cheyenne County Kansas. The storms are ongoing just north of the conglomerate surface front/outflow lying west-southwest to east-northeast across northwestern Kansas and into central and southeastern Nebraska. As such, this region is on the northern gradient of surface-based instability, and thus capable of producing all-hazards severe weather -- given favorably strong/sheared background flow. This convection should maintain intensity as it shifts eastward toward -- and eventually into -- WW 274, aided by the observed 60-kt low-level jet. ..Goss.. 05/21/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0140 AM CDT Tue May 21 2024 Valid 211200Z - 221200Z ...Synopsis... An upper trough will progress eastward today traversing the Rockies, while a mid-level jet slowly exits the Desert Southwest and High Plains. The entrance region of this jet, however, will remain over NM and far eastern AZ for most of the day. Deep westerly to southwesterly flow is still expected across the aforementioned states, albeit slower/weaker than Monday. West to southwest surface winds around 15 to 20 mph will develop this afternoon across much of NM and AZ, and RH will drop into the low teens to single digits. Sustained wind speeds across northern NM may briefly exceed 20 mph, where momentum transfer through a deeply mixed boundary layer and a tighter pressure gradient will reside. A Critical area does not appear warranted at this time, though, considering the duration of the higher speeds and less receptive fuels across this region. ..Barnes.. 05/21/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
