MD 0129 CONCERNING TORNADO WATCH 18... FOR EASTERN OKLAHOMA INTO FAR WESTERN ARKANSAS
Mesoscale Discussion 0129 NWS Storm Prediction Center Norman OK 0622 AM CST Tue Mar 04 2025 Areas affected...eastern Oklahoma into far western Arkansas Concerning...Tornado Watch 18... Valid 041222Z - 041445Z The severe weather threat for Tornado Watch 18 continues. SUMMARY...A squall line with history of damaging winds may remain severe as it approaches the Arkansas border. DISCUSSION...Surface analysis shows a warm front remains over northeast OK and extending southward roughly near the OK/AR border. Pressure falls are currently strong in this region with over 2 mb falls per hour noted. As such, it is likely that the low-level jet is transporting higher theta-e air northward, perhaps just off the surface. Therefore, while surface observations otherwise indicate weak/marginal instability extending into the northwest AR area, it is not inconceivable that the line remains severe into those areas with damaging wind potential. Depending on storm trends, an additional small watch cannot be ruled out. ..Jewell.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LZK...SHV...TSA...OUN...

MD 0130 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR ARKLATEX INTO THE SABINE VALLEY AND VICINITY
Mesoscale Discussion 0130 NWS Storm Prediction Center Norman OK 0749 AM CST Tue Mar 04 2025 Areas affected...Arklatex into the Sabine Valley and vicinity Concerning...Severe potential...Watch likely Valid 041349Z - 041545Z Probability of Watch Issuance...80 percent SUMMARY...A severe wind, and eventually tornado risk exists over the area, ahead of the cold front and near and south of the warm front. A watch may be considered. DISCUSSION...Although a greater threat of severe storms including tornadoes is expected into the afternoon, some severe risk may persist with the ongoing early day activity as a line of storms continues east out of TX and eastern OK. 12Z soundings indicate a capping inversion near 700 mb, by virtue of relatively cool surface conditions near the warm front. However, very strong southerly winds above the surface with the low-level jet, as well as areas of daytime heating will allow for a growing area of concern across the developing warm sector, including much of LA and into MS. In the near term, robust storms persist along the cold front over northeast TX, with a few counties width of warm sector west of the warm front. At least a few hours of severe risk likely remains in this area, prior to expected diurnal maximum, and a watch will likely be needed to address this early threat. ..Jewell/Smith.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0657 AM CST Tue Mar 04 2025 Valid 041300Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM SOUTHEASTERN OKLAHOMA/NORTHEASTERN TEXAS EAST-SOUTHEASTWARD TO SOUTHERN ALABAMA AND WESTERN PARTS OF THE FLORIDA PANHANDLE... ...SUMMARY... Severe thunderstorms with a threat for tornadoes, damaging winds, and isolated hail are possible today from eastern portions of the southern Plains into the lower Mississippi Valley and Southeast. A couple strong tornadoes will be possible. ...North and East Texas and Oklahoma eastward to the southern Appalachians/Southeast... Water-vapor imagery shows a large-scale mid to upper-level trough moving east across the central and southern High Plains this morning. Several embedded perturbations are rotating through the larger-scale upper feature with the most notable feature being a 100+ kt 500-mb speed max forecast to move from south-central TX through the lower MS Valley and into the TN Valley/Mid South tonight. Meanwhile a deepening surface low will move from KS into the mid MS Valley during the period as a cold front sweeps east across the Mid South and central Gulf Coast later today/tonight. A severe squall line is ongoing this morning from central TX north-northeastward into eastern OK. Intense shear profiles within an adequately unstable warm/moist sector will favor severe gusts with the bowing segments as this mature squall line rapidly moves east across eastern OK/TX this morning. A risk for a few tornadoes will accompany the band of storms as this activity moves east across the Ark-La-Tex and into the Ark-La-Miss during the day. Forecast soundings show very large hodographs which will support storm-scale rotation with the stronger cells either embedded within or that can develop ahead of the squall line. Strong tornado potential exists given the wind field across the lower MS Valley where diurnal destabilization and northward-returning Gulf moisture will aid in storm intensity/coverage. This activity will likely maintain a linear mode tonight as it moves east across the central Gulf Coast states into the TN Valley. A continued risk for damaging gusts and tornadoes will become the primary severe hazards. Have expanded Slight-Risk and Enhanced-Risk equivalent severe probabilities farther east across southern AL and southwestern GA where confidence in a surface-based severe threat appear greatest. ...Eastern Kansas to western Illinois... As the upper low pivots eastward across Oklahoma and Kansas through the day, and into Missouri by evening, cold air aloft accompanying the low will yield steep mid-level lapse rates. Any daytime heating in the wake of initial/prior convection across the northeastern Kansas vicinity could yield enough CAPE for isolated, low-topped convective redevelopment. Assuming this scenario manifests, a couple of the strongest storms could pose marginal risk for hail/wind and possibly a tornado. Any such risk would taper by evening. Farther east, across Missouri and into western Illinois, elevated storms east of the primary zone of convection may pose limited/local risk for marginal hail during the morning and into the afternoon hours. ..Smith/Bentley.. 03/04/2025 Read more

MD 0128 CONCERNING TORNADO WATCH 18... FOR NORTH TEXAS INTO SOUTHEAST OKLAHOMA
Mesoscale Discussion 0128 NWS Storm Prediction Center Norman OK 0513 AM CST Tue Mar 04 2025 Areas affected...north Texas into southeast Oklahoma Concerning...Tornado Watch 18... Valid 041113Z - 041315Z The severe weather threat for Tornado Watch 18 continues. SUMMARY...Damaging winds likely to persist across north Texas into southeast Oklahoma. A brief tornado remains possible as well. DISCUSSION...A squall line has gained strength and speed over the past few hours, and will continue to push east across northern TX and southeastern OK. Widespread strong to damaging winds are likely, with substantial/cold downdrafts augmenting the already strong boundary-layer wind gusts well ahead of the line. Recently, a gradually deepening line of convection was noted near Waco, stretching north and intersecting the squall line as it moves into the Metroplex. This intersection may prove favorable for enhanced severe winds over 75 mph, along with stronger cyclonic shear. Given the continued push to the shortwave trough and strong low-level jet, this line should remain severe for several more hours. ..Jewell.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product...

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0353 AM CST Tue Mar 04 2025 Valid 071200Z - 121200Z ...DISCUSSION... In the wake of renewed cyclogenesis across and north of the Canadian Maritimes, it appears that a broad area of lower mid-level heights will linger across the Great Lakes and Northeast late this week through the coming weekend. This may contribute to the maintenance of a confluent mid-level regime to the east of the Rockies, as much of the western and southern U.S. remains under the influence of one prominent belt of westerlies emanating from the mid-latitude Pacific. One embedded short wave trough digging into the Southwest with an evolving mid-level low by early Friday is forecast to progress across the southern Rockies by 12Z Saturday. Subsequent development across and east of the southern Great Plains over the weekend into early next week remains much more unclear. ECENS/ECMWF-based guidance suggests that this feature emerges as an increasingly sheared perturbation across the southern tier, supportive of only low amplitude frontal wave development, until progressing across and east of the south Atlantic Seaboard. GEFS/GFS-based guidance forecasts similar shearing across the southern Great Plains, before phasing with an amplifying wave within the cyclonic regime initially confined to the Great Lakes vicinity. This would probably be accompanied by more substantive cyclogenesis, with a moistening and destabilizing warm sector which could become supportive of organized severe weather potential. Thereafter, through the early to middle portion of next week, models indicate that, as the persistent area of lower mid-level heights retreats to the north and east, mid/upper flow may become more supportive of strong cyclogenesis across Nebraska into the mid/lower Missouri Valley by late next Tuesday night. However, it appears that this will occur before the boundary-layer over the northwestern Gulf recovers sufficiently to support a substantive moist return flow. Read more

SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0203 AM CST Tue Mar 04 2025 Valid 061200Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Widely scattered weak thunderstorm activity is possible Thursday across parts of central California through the Great Basin and parts of the southern Rockies. ...Discussion... As the center of a broad and deep, occluding cyclone migrates into southwestern Quebec by early Thursday, a significant trailing cold front is forecast to have overspread much of the Gulf Basin. It does appear that the boundary layer may begin to undergo substantive modification across the southwestern Gulf Basin, northward toward lower Texas coastal areas by late Thursday night. However, dry,stable conditions are likely to prevail across much of the southern Great Plains, as renewed cyclogenesis occurs to the lee of the Colorado Rockies. Beneath a generally confluent mid-level flow regime, it still appears that the cyclone, and supporting mid-level short wave perturbation emerging from larger-scale troughing progressing inland of the Pacific coast, will weaken while shifting eastward through the central Great Plains Thursday night into early Friday. Trailing the lead short wave, models indicate that a more prominent mid-level short wave trough will dig inland across central/southern California and into the lower Colorado Valley by 12Z Friday. Cold mid-level air overspreading central California through the southern Great Basin and portions of the southern Rockies, in association with these developments, is likely to contribute to weak destabilization with daytime heating. It appears that this will become sufficient to support widely scattered weak thunderstorm activity. ..Kerr.. 03/04/2025 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0140 AM CST Tue Mar 04 2025 Valid 051200Z - 061200Z ...NO CRITICAL AREAS... ...Synopsis... Upper ridging will build over the Plains states as a mid-level trough ejects into the Atlantic and a second upper trough amplifies across the Southwest tomorrow (Wednesday). As such, relatively more quiescent wildfire-spread conditions are likely across the southern Plains compared to previous days. Broad northwesterly mid-level flow may transport downward via a mixed boundary-layer mixing across the southern Plains. However, marginal RH and the recent occurrence of appreciable rainfall accumulations precludes Elevated highlights at this time. Dry and occasionally breezy conditions will also return to eastern New Mexico ahead of the aforementioned approaching upper trough. However, surface winds appear too weak on a widespread basis to justify the addition of fire weather highlights this outlook. ..Squitieri.. 03/04/2025 ...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 0132 AM CST Tue Mar 04 2025 Valid 041200Z - 051200Z ...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHWESTERN TEXAS TO THE TEXAS HILL COUNTRY... ...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST NEW MEXICO INTO SOUTHERN TEXAS... ...Synopsis... A mid-level trough will traverse the Mississippi Valley as a surface low tracks toward the Great Lakes while deepening today. The net result will be intense isallobaric flow, transporting a dry low-level airmass across portions of the southern High Plains into southern Texas. The combination of very strong winds/low RH overspreading critically dry fuels across western into southern Texas will promote extreme wildfire-spread potential. Meanwhile, a plume of low-level dry air will advect northward across portions of the central Appalachians as the surface low approaches. The accompanying dry and breezy conditions atop dry duels over the central Appalachians will promote some potential for wildfire spread in this region as well. ...Southern High Plains into southern Texas... Though the surface low will drift away from the southern Plains through the period, the gradual intensification of the low will slow the weakening of the surface wind field. Furthermore, daytime boundary-layer mixing will encourage some downward momentum of stronger flow aloft. As such, portions of western into southern Texas will see multiple hours of sustained west-northwesterly surface winds well over 30 mph coincide with very low RH (i.e. 10-15 percent over several locales). Such conditions, particularly over the Edwards Plateau into the Central Texas Hill Country and South Texas Brush Country, are anomalously favorable for very rapid wildfire spread/extreme fire behavior. Given the very dangerous wildfire-spread conditions, Extremely Critical highlights have been maintained for this region. Furthermore, Extremely Critical highlights have been introduced to portions of southeast New Mexico into the Trans Pecos and Permian Basin regions in southwestern TX. An 850 mb speed maxima pivoting around the backside of the mid-level trough will overspread the mixed boundary layer, with downward momentum transport fostering 30 mph sustained northwesterly surface winds amid 15 percent RH. A complicating factor to this outlook is the development and progression of ongoing strong thunderstorms across portions of western into northern Texas. Additional storms may produce an abundance of rainfall in some locations, dampening fuels sufficiently to reduce wildfire-spread potential to some degree. As such, considerable modifications to the ongoing fire weather highlights may be needed for the Day 1 Outlook Update. ...Central Appalachians... By afternoon peak heating, Rh will drop to around 30-35 percent in spots as sustained southerly winds increase to around 15 mph. During the mid-afternoon time frame, some moistening of the surface airmass will occur as surface wind speeds increase, so the window of opportunity for favorable wildfire-spread conditions is not expected to be particularly long-lived. Nonetheless, these aforementioned conditions should overspread fuels that are quite dry, warranting the continuance of Elevated highlights. ..Squitieri.. 03/04/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
