SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0352 PM CST Tue Mar 04 2025 Valid 061200Z - 121200Z The potential for critical fire weather conditions will persist through the end of the week, and into next week, as several mid to upper-level troughs move through an amplified pattern. ...Southern Plains and New Mexico... By early Day3/Thursday an upper ridge is expected to traverse the Central and Southern Plains, while a progressive trough enters the Southwest. Breezy west to southwest downslope winds and warm temperatures will accompany this feature, as a lee surface low deepens over eastern CO and the pressure gradient tightens across NM. Although some mid-layer cloud cover may initially inhibit mixing through the first half of the day, deeper mixing will allow for stronger gusts during the late afternoon hours. This will especially be true across southeastern NM, where low RH will overlap with deteriorating fuel states. A continuation of this pattern is expected D4/Friday as the first trough progresses eastward and another Pacific trough behind it digs southeastward over southern CA. The critical conditions D4/Friday will shift more over West TX, however, and wind speeds should decrease with far less of a pressure gradient present. These speeds appear they will be just high enough to continue with critical probabilities during this time across West TX. Fairly good agreement between global deterministic and extended ensemble solutions continues into D5/Saturday with the aforementioned trough and it's associated mid-level jet max impacting the Big Bend and Hill Country of TX. However, there is some disagreement at the surface concerning the progression of a cold front and placement of the tightest pressure gradient. For this reason only minor adjustments have been made to the low critical probabilities, and an increase in probabilities is not warranted at this time. By D8/Tuesday most solutions suggest yet another progressive trough impacting the Southwest and Southern Plains. Although there are still uncertainties regarding the depth and exact timing of this wave, confidence is high enough to conclude breezy and dry conditions will likely be present from southern NM, to West TX, and the TX Panhandle. A low Critical probability area has been included to account for this persistent pattern. ..Barnes.. 03/04/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 0135 CONCERNING TORNADO WATCH 21... FOR SOUTHERN MISSISSIPPI AND SOUTHERN ALABAMA
Mesoscale Discussion 0135 NWS Storm Prediction Center Norman OK 0214 PM CST Tue Mar 04 2025 Areas affected...southern Mississippi and southern Alabama Concerning...Tornado Watch 21... Valid 042014Z - 042145Z The severe weather threat for Tornado Watch 21 continues. SUMMARY...The greatest tornado threat this afternoon will be across southern Mississippi and southern Louisiana. DISCUSSION...The warm sector is slowly expanding eastward across southern Mississippi with upper 60s dewpoints now across southern Louisiana. Thunderstorms development continues along and slightly ahead of a cold front extending from near the ArkLaMiss to the central Louisiana Gulf Coast. A few embedded supercells have produced transient circulations and some severe wind gusts, but a strong, mature supercell has yet to form. This remains a possibility this afternoon as convection continues to develop and slowly deepen across southern Louisiana and Mississippi. The supercell tornado threat this afternoon will increase if a large enough area of greater instability (1000-1500 J/kg MLCAPE) can develop. However, this is seemingly less likely as eastward warm sector expansion remains slow with expansive cloud cover. Nonetheless, even without mature supercells, a damaging wind and embedded tornado threat will continue through the afternoon and into the evening with very strong low-level flow (70 knots at 1.5 km per JAN 19Z RAOB). ..Bentley.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0133 CONCERNING HEAVY SNOW FOR EASTERN SOUTH DAKOTA INTO FAR SOUTHWESTERN MINNESOTA AND FAR NORTHERN NEBRASKA
Mesoscale Discussion 0133 NWS Storm Prediction Center Norman OK 1025 AM CST Tue Mar 04 2025 Areas affected...Eastern South Dakota into far southwestern Minnesota and far northern Nebraska Concerning...Heavy snow Valid 041625Z - 042030Z SUMMARY...Localized moderate to heavy snowfall rates on the order of 1-2 inches/hour will be possible as snow bands develop across eastern South Dakota into far western Minnesota and far northern Nebraska. DISCUSSION...Transient snow banding has been observed across eastern SD into northern NE over the past couple of hours with surface observations and web cams under these bands showing localized areas of visibility reductions down to 1/4 to 1/2 mile. These bands are largely being driven by focused ascent within a 700 mb deformation zone augmented by modest warm advection/frontogenesis through the 850-700 mb layer. Additionally, steep lapse rates within this zone are supporting localized areas of convectively-augmented precipitation rates (as evidenced by recent lightning strikes over the SD/NE/IA border). This deformation zone will continue to be a preferential area of transient precipitation band development through the late morning and early afternoon hours. Areas to the north/northwest of the surface freezing line may experience periods of moderate to heavy snowfall rates (1-2 inches/hour) as transient snow bands emerge. Given surface gradient winds sustained at 20-25 mph (gusting to 30-40 mph at times), localized areas of whiteout conditions (visibility below 1/4 mile) appear possible under more organized bands. ..Moore.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product...
