SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0354 PM CDT Mon Apr 01 2024 Valid 031200Z - 091200Z A large-scale upper-level trough will be positioned over the central CONUS on D3/Wed, with a high amplitude ridge positioned over the West. By D4/Thu another upper-level trough will enter the West Coast while the general upper-level pattern shifts east. Strong mid-level flow associated with this trough will begin overspreading the southern/central CONUS by D5/Fri and persist through D7/Sun. Thereafter, evolution of the upper-level pattern becomes more uncertain. D5/Fri - D7/Sun: Southern/Central High Plains: Medium-range guidance continues to depict agreement in the potential for multiple days of wide-spread fire-weather conditions across the Southern/Central High Plains and adjacent regions. The aforementioned strong southwesterly mid-level flow should persist atop boundary layer conditions that are well-mixed. This will promote sustained winds exceeding 20 mph and RH values falling below 15% each day. Fuels are presently at least marginally receptive to large-fire spread, with ERC values exceeding 90% in at least localized areas of the region. For this outlook, the 40% and 70% probabilities have been maintained on D5/Fri and D6/Sat, and 40% probabilities have been introduced for the region on D7/Sun. These delineations have been confined to the most probable areas for critical fire-weather potential based on depictions/spread in the medium-range guidance. ..Karstens.. 04/01/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 0324 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR FAR EASTERN KANSAS INTO WESTERN MISSOURI
Mesoscale Discussion 0324 NWS Storm Prediction Center Norman OK 0301 PM CDT Mon Apr 01 2024 Areas affected...Far eastern Kansas into western Missouri Concerning...Severe potential...Tornado Watch likely Valid 012001Z - 012130Z Probability of Watch Issuance...95 percent SUMMARY...Storms capable of all severe hazards will move into far eastern Kansas and western Missouri later this afternoon. A tornado watch is likely within the next hour. DISCUSSION...Storms have initiated in far northeast Kansas and have moved into northwest Missouri. Additional storms are likely to move into western Missouri from north-central Oklahoma/southeast Kansas over the next few hours. While timing of storm arrival in southwestern Missouri is not certain, weak convection with lightning has developed in northeastern Oklahoma and is moving northeast. That all said, the severe risk for far eastern Kansas and western Missouri will be increasing late this afternoon into the evening. Large/very-large hail, damaging winds, and tornadoes will all be possible. Low-level shear, particularly for southwest Missouri, will initially be weak. However, the low-level jet will increase by early evening. A tornado watch is likely within the next hour. ..Wendt/Thompson.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0322 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR MUCH OF OK AND NORTHWEST TX
Mesoscale Discussion 0322 NWS Storm Prediction Center Norman OK 0155 PM CDT Mon Apr 01 2024 Areas affected...Much of OK and Northwest TX Concerning...Severe potential...Tornado Watch likely Valid 011855Z - 012100Z Probability of Watch Issuance...95 percent SUMMARY...Supercell thunderstorms are expected this afternoon from northwest Texas across much of Oklahoma. Threat with these storms will include very large hail (3"+), strong gusts (60-80 mph), and tornadoes. DISCUSSION...Recent surface analysis places a triple point low about 20 miles west-northwest of END, with dryline extending southwestward from this low through southwest OK and into southwest TX. Thunderstorms have developed in the vicinity of this surface low, amid persistent low-level convergence and warm-air advection. There is still some low-level stability remaining within the air mass. As such, this initial development is likely elevated, but steep mid-level lapse rates and strong deep-layer vertical shear are more than sufficient for updraft organization. Large to very large (1" to 2.75") is possible with this activity. Continued low-level moisture advection and filtered heating will likely lead to gradual air mass destabilization, with additional storms developing later this afternoon along and ahead of the dryline as the shortwave (and associated ascent) continues to lift northeastward. This activity would likely be surface based and capable of all severe hazards, including very large hail (3"+), strong gusts (60-80 mph), and tornadoes. A Tornado Watch will be issued soon to cover these potential hazards. ..Mosier/Thompson.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TSA...FWD...OUN...SJT...LUB...

MD 0321 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PARTS OF WEST AND CENTRAL TEXAS
Mesoscale Discussion 0321 NWS Storm Prediction Center Norman OK 0213 PM CDT Mon Apr 01 2024 Areas affected...Parts of west and central Texas Concerning...Severe potential...Watch likely Valid 011913Z - 012045Z Probability of Watch Issuance...80 percent SUMMARY...Monitoring the area for increasing severe-storm potential. Large hail and severe gusts are the main concerns. A watch is likely in the next 30 minutes or so. DISCUSSION...Isolated storms are developing along the dryline this afternoon, and this activity will generally spread east-northeastward through the afternoon -- in conjunction with an approaching lobe of midlevel ascent. While initial storms may be high-based with a localized severe risk, the risk will gradually increase over the next few hours as storms move into moderate/strong surface-based buoyancy and rapidly increasing deep-layer shear. Generally straight hodographs will favor large to very large hail and severe winds with supercells and organized clusters. A watch is likely in the next 30 minutes or so. ..Weinman/Thompson.. 04/01/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...SJT...LUB...MAF...
