SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0202 AM CDT Mon May 20 2024 Valid 211200Z - 221200Z ...Synopsis... Moderate mid-level flow will remain across the Southwest on Tuesday with single-digit relative humidity across New Mexico. As deep mixing develops during the afternoon, some of this stronger flow will mix to the surface. In addition, a secondary lee cyclone is expected to develop in the TX/OK Panhandle vicinity. This will also aid in stronger surface winds. 15 to 25 mph sustained surface winds are expected across much of New Mexico. Locally critical conditions are probable and a Critical delineation may be needed at a later time, but for now, it is unclear where within the broader Elevated area, the greater threat may be. ..Bentley.. 05/20/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0202 AM CDT Mon May 20 2024 Valid 201200Z - 211200Z ...Synopsis... A mid-level jet streak will overspread the Southwest this afternoon as a mid-level trough amplifies across the western CONUS. A deeply mixed boundary layer is expected across Arizona and New Mexico with temperatures in the 90s. Some of this stronger flow will mix to the surface amid the deep boundary layer. In addition, lee cyclogenesis will tighten the pressure gradient in the region and aid in stronger surface winds. Sustained surface winds of 25 to 30 mph are expected across New Mexico with some sustained winds over 30 mph in northern Arizona. Single-digit relative humidity is also expected across most of the region. Fuels have started to dry to critical levels across portions of eastern and northern Arizona. Therefore, a Critical delineation is warranted. ..Bentley.. 05/20/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0137 PM CDT Thu May 16 2024 Valid 171200Z - 181200Z ...NO CRITICAL AREAS... ...2000Z Update... A surface low will deepen in the lee of the northern Rockies over the High Plains of southeast Montana and northeast Wyoming Friday in association with an approaching mid-level trough. The resulting pressure gradient will support breezy westerly sustained surface winds around 20 to 30 mph from central Montana into Idaho and southwest Wyoming. There's still some disagreement on how low RH will drop across northeast Idaho and far western/southwestern Wyoming, as mentioned in the previous forecast. Regardless, recent rainfall over this region and relatively low fuel receptiveness will limit the overall fire spread threat. ..Barnes/Nauslar.. 05/16/2024 .PREV DISCUSSION... /ISSUED 0122 AM CDT Thu May 16 2024/ ...Synopsis... A pronounced mid-level trough will eject into the northern Plains today, supporting strong surface lee troughing over the northern High Plains tomorrow (Friday). A widespread, strong surface wind field will develop over Wyoming and points eastward as a result. However, guidance varies considerably in terms of how low RH will drop by afternoon peak heating, with some guidance members showing RH dropping as low as 15 percent in some spots, while other members show RH staying well above 25 percent in many locales. When also considering recent rainfall that portions of the northern Plains has received in the past week, fuel receptiveness to wildfire spread should also be mediocre. Fire weather highlights have been withheld given the aforementioned uncertainties with RH and fuels. Nonetheless, localized instances of wildfire growth cannot be ruled out where dry fuel beds exist given the strong winds. ...Please see www.spc.noaa.gov/fire for graphic product...

MD 0802 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR SOUTHEAST TEXAS INTO SOUTHWEST LOUISIANA
Mesoscale Discussion 0802 NWS Storm Prediction Center Norman OK 0112 PM CDT Thu May 16 2024 Areas affected...southeast Texas into southwest Louisiana Concerning...Severe potential...Watch likely Valid 161812Z - 162045Z Probability of Watch Issuance...80 percent SUMMARY...Storms are likely to develop after 19Z from southeast Texas into southwest Louisiana. Large hail as well as damaging gusts will be likely, and a brief tornado will be possible as well. DISCUSSION...A line of storms stretching from central into northeast TX continues to shift east/southeast, with prominent outflow. Although the air mass ahead of this line continues to gradually destabilize due to heating, a surge of rich boundary layer moisture is moving in from the southwest, and this will provide a greater contribution. GPS PWAT values will increase rapidly by over 0.50" as the mid to upper 70s F dewpoints arrive. Indicative of this robust moisture are cells forming within the warm advection zone just off the LA Coast. Therefore, as the primary line of storms moves in from the northwest, strengthening may occur especially where the line intersects the warm front, with additional cells forming along the length of the warm front. Damaging hail and wind will be likely. Low-level shear along the warm front may support a brief tornado or two as well, with 0-1 SRH values above 100 m2/s2. ..Jewell/Jewell.. 05/16/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1226 PM CDT Thu May 16 2024 Valid 171200Z - 181200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN PARTS OF THE GULF COAST STATES... ...SUMMARY... Scattered severe thunderstorms with a few tornadoes, very large hail, and damaging winds are possible across parts of the Gulf Coast States on Friday through Friday night. ...South-central to Southeast States... A messy severe weather setup is expected on Friday into Friday night amid a series of low-amplitude impulses ejecting within and around the positive-tilt, southern-stream shortwave trough across the southern Great Plains. Synoptic surface pattern appears nebulous and likely driven on the mesoscale by several rounds of convection today through the end of D2. Primary changes with this outlook are to expand severe probabilities west and east, while reducing probabilities across the northern portion of the threat area. An MCS or clustered remnants of an early morning one should be ongoing at 12Z Friday across parts of the central Gulf Coast region. Outflow from this preceding D1 activity will serve as the focus for renewed thunderstorm development later in the day. Most guidance suggests a separate area of upstream convection may be ongoing or will develop by midday across parts of south TX and the TX Gulf Coast along and behind the composite outflow/cold front that will surge southeast in TX on D1. With the fastest mid-level southwesterlies expected to overlie the western to central Gulf Coast during the first half of the period, supercells capable of very large hail will be possible. This threat should be focused in a narrow corridor along the TX Gulf Coast initially, and then develop later in the afternoon to evening in the central Gulf Coast. Some of this latter activity will have relatively greater potential for tornado/wind threats, focused along the outflow in the wake of the early-morning MCS. Additional isolated to scattered thunderstorm development should occur within the post-frontal/outflow air mass centered on parts of the Red River Valley and in south-central TX near the Rio Grande. This activity will likely be aided by the embedded low-amplitude impulses within the southern-stream shortwave trough. Residual buoyancy should be adequate for an isolated hail/wind threat amid more muted deep-layer shear closer to the trough axis. ...Northern Great Plains... A vigorous, northern-stream shortwave trough will move across the northern Rockies into the Prairie Provinces and adjacent parts of MT/ND through early Saturday. Primary surface cyclone will occlude over SK/MB, with secondary cyclogenesis occurring near the SD/WY/MT border area along the trailing Pacific cold front. With only modified moisture return ahead of the front, MLCAPE will remain rather weak. Initial convective development will probably occur within the post-frontal upslope flow regime during the early to mid afternoon. This activity should spread east and likely expand during the late afternoon into the evening. With deeply mixed thermodynamic profiles ahead of the front, and steep lapse rates being maintained behind it, high-based thunderstorms with amalgamating outflows are expected. While the bulk of strong 700-500 mb westerlies will lag behind the front, the strengthening flow should support a threat for strong to isolated severe surface gusts before convection wanes after dusk. ..Grams.. 05/16/2024

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1141 AM CDT Thu May 16 2024 Valid 161700Z - 171200Z ...1700Z Update... A cold front has moved through most of the Permian Basin this morning, with a dryline already pushing eastward into the lower Trans Pecos and Big Bend region. This eastward moving trend of the dryline will continue through afternoon as mostly clear skies allow for good to excellent mixing conditions. Very warm afternoon temperatures from the Davis Mountains southward into the Big Bend, along with dewpoints in the upper teens to low 20s, will result in RH dropping as low as the single digits. West to northwest sustained 15-20 mph winds are still anticipated, with localized Critical sustained winds of 20-25 mph later this afternoon near and south of the Davis Mountains. The only minor change to the Elevated area was to eliminate a small portion of the northern extent based on the current position of the cold front and its slow progression to the south throughout the afternoon. ..Barnes/Nauslar.. 05/16/2024 .PREV DISCUSSION... /ISSUED 0121 AM CDT Thu May 16 2024/ ...Synopsis... A mid-level trough will traverse the southern Plains as a weak surface low develops near the Rio Grande today. Behind the low, isallobaric and downslope northwesterly flow will overspread the Trans Pecos region of Texas during the afternoon. 15+ mph sustained northwesterly surface winds will coincide with 10-20 percent RH and dry fuels, warranting the continuation of Elevated highlights. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1133 AM CDT Thu May 16 2024 Valid 161630Z - 171200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON INTO EARLY TONIGHT FROM CENTRAL/SOUTHEAST TX INTO SOUTHWEST LA... ...SUMMARY... Thunderstorms capable of large hail and damaging winds are expected to increase across parts of central/southeastern Texas into southwest Louisiana this afternoon into tonight. A couple of tornadoes are also possible. ...Central TX to southern LA through tonight... Multiple clusters of thunderstorms are ongoing this morning across north and central TX, generally along and to the immediate cool side of a composite outflow boundary. Rich low-level moisture (100 mb mean mixing ratios 16-18 g/kg), steep midlevel lapse rates of 8-9 C/km and large buoyancy (MLCAPE near or above 3000 J/kg) are present south of the storms, along with sufficient deep-layer shear for organized clusters/supercells. Thus, some upscale growth and increased storm organization is expected from late morning into the afternoon, as storms move east-southeastward along the moisture/buoyancy gradient across central and southeast TX. Damaging wind of 60-75 mph will be possible with embedded bowing segments, while isolated very large hail will be possible with supercells on the south flank of the larger storm cluster(s). A couple of tornadoes will also be possible with embedded circulations and/or favorable storm interactions near or south of the composite outflow boundary. One or more clusters/bowing segments could persist into tonight across southern LA. Other storms will likely form immediately ahead of the primary shortwave trough moving from southern NM toward west TX. Given the ongoing reinforcement of the rain-cooled air mass, any convection this afternoon from the Permian Basin into the Edwards Plateau will likely be elevated atop the outflow spreading southwestward. Wind profiles will favor supercells, with the primary threat of large hail. ...Elsewhere... No substantial changes to the low-end severe threats in the MRGL areas across the Ozarks, WI, and southeast FL. ..Thompson/Thornton.. 05/16/2024
