As crawfish producers struggled to provide many of the crustaceans after a hot, dry summer, Louisiana Gov. Jeff Landry issued a disaster declaration for the industry and stated that the shortage affected the state’s economy and also “our way of life.” The Louisiana State University’s Agriculture Center estimated the potential loss to the state’s crawfish industry to be nearly $140 million. One year ago, a pound of boiled crawfish cost between $3 to $5, but restaurants were presently charging $10 to $12 per pound, as reported by The Advocate. The Associated Press, March 6, 2024

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1143 PM CST Wed Mar 06 2024 Valid 071200Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON INTO TONIGHT ACROSS PARTS OF THE EASTERN TEXAS PANHANDLE AND NORTHWESTERN OKLAHOMA INTO SOUTHERN KANSAS...AND ACROSS PARTS OF WEST CENTRAL INTO NORTH CENTRAL TEXAS... ...SUMMARY... A few thunderstorms may pose primarily a risk for severe hail and locally strong wind gusts across parts of the southern Great Plains this afternoon into tonight. ...Synopsis... Flow across the mid-latitude Pacific is becoming more amplified and, later today through tonight, models indicate this will include building mid/upper ridging spreading inland across the Pacific coast. Preceding this ridge, while one short wave trough digs near/west of the Sierra Nevada, toward the Southwestern international border, a downstream perturbation is forecast to accelerate east-northeastward out of the Southwest, into the southern Great Plains by early Friday. In the wake of a vigorous short wave trough slowly accelerating from southern Manitoba toward the southern Hudson/James Bay vicinity, a significant cold intrusion is already underway to the lee of the northern Rockies. As this air continues to nose southward through the high plains, modestly deep surface troughing will precede it across the southern Great Plains through lower Missouri Valley, but guidance suggests little in the way of embedded surface cyclogenesis through this period. One evolving wave along a developing frontal zone may shift from the Texas Panhandle/northwestern Oklahoma vicinity into the lower Missouri Valley late this afternoon through tonight. A narrow plume of better low-level moisture return may be ongoing across the lower Rio Grande Valley into the San Angelo/Abilene vicinity by 12Z this morning, before more substantive low-level moisture return commences across the western Gulf/northwestern Gulf coast and coastal plain toward the southeastern Great Plains/lower Mississippi Valley. Much of the this, however, may take place beneath relative warm layers in the lower/mid-tropospheric and layers further aloft, beneath low-amplitude subtropical ridging. ...Southern Great Plains... Considerable thunderstorm development may be ongoing by 12Z this morning, in response to ascent supported by lower/mid-tropospheric warm advection, beneath difluent high level flow, from parts of west central/northwest Texas into Kansas, Missouri and Arkansas. Steeper mid/upper level lapse rates supportive of somewhat better potential for severe hail in widely scattered stronger storms probably will be initially focused from the Kansas/Oklahoma border vicinity toward the Ozark Plateau. However, as convection across this region becomes more widespread and spreads northeastward, the initial risk for severe hail is expected to wane. There is considerable model output indicating that a more prominent cluster of convection may evolve through late morning into afternoon across parts of west central through north central Texas, perhaps aided by weak perturbation associated with the subtropical jet. This may include a gradually intensifying line, supported by better near-surface moist inflow along the leading (southern and eastern) edge of associated convective outflow, which may eventually pose at least some risk for severe hail and wind. However, this potential may be limited by generally weak lapse rates, particularly as it continues eastward through the day. While convective development to the south may impede better low-level moisture return, a narrow corridor of stronger pre-frontal daytime heating across the Texas Panhandle toward the Wichita, KS vicinity will provide at least one focus for stronger late afternoon into evening thunderstorm development. Beneath the leading edge of stronger mid/upper cooling associated with the troughing emerging from the Southwest, steepening lapse rates will contribute to an environment conducive to potential for at least severe hail, in the presence of sufficient shear for supercells. In the wake of early day convection, an appreciable increase in potential for strong/severe thunderstorm development will await mid-level forcing for ascent and cooling aloft associated with the primary short wave perturbation emerging from the Southwest. This may not reach the Edwards Plateau vicinity until mid/late evening, before spreading toward the Interstate 35 corridor of central into northern Texas overnight. But it appears that boundary-layer based instability will probably become supportive of supercells, beneath 60-70+ kt southwesterly mid-level flow. Low-level hodographs may not become particularly large, but some risk for a tornado and locally damaging wind gusts may accompany stronger cells, in addition to severe hail. ..Kerr/Weinman.. 03/07/2024 Read more

Thunderstorms are likely to increase overnight across the southern into central Great Plains and portions of the Ozark Plateau, with widely scattered stronger cells posing at least some risk for severe hail. ...01Z Update... A short wave impulse, within negatively-tilted larger-scale mid-level trough now shifting across the southern Atlantic Seaboard, remains fairly vigorous as it progresses east-northeast of the southern Appalachians. Associated forcing for ascent and mid-level cooling appear to have aided a recent increase in thunderstorm development across the South Carolina coastal plain. However, destabilization remains modest, with the onset of diurnal cooling likely to further limit destabilization into the North Carolina coastal plain, as the mid-level perturbation becomes increasingly sheared across the southern Mid Atlantic coast vicinity this evening into the overnight hours. In the wake of the larger-scale scale mid-level troughing, models suggest at least some low-level drying may occur tonight across much of the northern into northwestern Gulf Basin. However, modest low-level moistening which has already occurred inland of the northwestern Gulf coast is forecast to continue to advect northward/northwestward through the southern into central Great Plains and parts of the Ozark Plateau, downstream of large-scale mid-level troughing turning inland of the Pacific coast into the Southwest. Aided by large-scale ascent associated with lower/mid-tropospheric warm advection, beneath at least broadly difluent and divergent upper flow, destabilization is forecast to support an increase in thunderstorm activity overnight across a fairly broad area. While models suggest a narrow plume of better low-level moisture return across the lower Rio Grande Valley into the San Angelo/Abilene vicinity by daybreak Thursday, a combination of capping layers below the 700 mb level, and above 500 mb (beneath high-level ridging overspreading the southern Great Plains), might suppress thunderstorm intensities. Still, a relatively cool layer between (including temps around or below -15C) might support thunderstorm activity capable of producing small to marginally severe hail. Model forecast soundings indicate steeper mid/upper lapse rates associated with colder air aloft, supporting the development of larger elevated destabilization, north of the Red River into portions of south central/southeastern Kansas and southwestern Missouri. Coupled with at least modest cloud-bearing layer shear, scattered stronger cells overnight probably will pose at least some risk for severe hail. ..Kerr.. 03/07/2024 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0217 PM CST Wed Mar 06 2024 Valid 081200Z - 141200Z A mid-level trough will traverse the southern U.S. as a surface cold front sweeps across the southern Plains Day 3/Friday. Critically dry and windy conditions will likely coincide with the International border late Friday afternoon. It is unclear how much of this area may experience appreciable precipitation accumulations in the Thursday-Friday time frame, precluding the addition of 70 percent Critical probabilities at this time. Thereafter, another mid-level trough will approach the central CONUS and promote strong surface lee troughing across the Plains states early to mid next week. Downslope flow may support critically dry and windy surface conditions across the southern High Plains through at least Days 6-7/Monday-Tuesday, where 40 percent Critical probabilities have been introduced. There is also the possibility that these conditions may persist into Day 8/Wednesday. However, details on the exact timing and evolution of next week's mid-level trough remain uncertain, precluding higher Day 6-7 Critical probabilities and any Day 8 probabilities this outlook. The latest medium range guidance is also hinting at the possibility for Critically dry/windy conditions across portions of the central into northern Plains early to mid next week. However, these conditions may be preceded by appreciable rainfall accumulations, so Critical probabilities have been withheld until the impacts of any potential future rainfall become clearer. ..Squitieri.. 03/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

The latest medium range guidance is also hinting at the possibility for Critically dry/windy conditions across portions of the central into northern Plains early to mid next week. However, these conditions may be preceded by appreciable rainfall accumulations, so Critical probabilities have been withheld until the impacts of any potential future rainfall become clearer. ..Squitieri.. 03/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0217 PM CST Wed Mar 06 2024 Valid 081200Z - 141200Z A mid-level trough will traverse the southern U.S. as a surface cold front sweeps across the southern Plains Day 3/Friday. Critically dry and windy conditions will likely coincide with the International border late Friday afternoon. It is unclear how much of this area may experience appreciable precipitation accumulations in the Thursday-Friday time frame, precluding the addition of 70 percent Critical probabilities at this time. Thereafter, another mid-level trough will approach the central CONUS and promote strong surface lee troughing across the Plains states early to mid next week. Downslope flow may support critically dry and windy surface conditions across the southern High Plains through at least Days 6-7/Monday-Tuesday, where 40 percent Critical probabilities have been introduced. There is also the possibility that these conditions may persist into Day 8/Wednesday. However, details on the exact timing and evolution of next week's mid-level trough remain uncertain, precluding higher Day 6-7 Critical probabilities and any Day 8 probabilities this outlook.

MD 0195 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR FAR EASTERN GEORGIA INTO SOUTH CAROLINA
Mesoscale Discussion 0195 NWS Storm Prediction Center Norman OK 1241 PM CST Wed Mar 06 2024 Areas affected...Far eastern Georgia into South Carolina Concerning...Severe potential...Watch unlikely Valid 061841Z - 062045Z Probability of Watch Issuance...20 percent SUMMARY...Strengthening thunderstorms may pose a damaging wind and hail threat across parts of far eastern Georgia into portions of South Carolina over the next several hours. This threat is expected to remain sufficiently limited to negate the need for a watch. DISCUSSION...Shallow convection across central GA has shown signs of intensification over the past 30-60 minutes based on lightning and cloud-top temperature trends. This is likely in response to gradual destabilization across the region as temperatures warm into the low to mid 70s to the south of a lingering surface trough/frontal boundary. Low-level warming appears to be somewhat faster than depicted by recent guidance, suggesting that the downstream environment is becoming increasingly favorable for sustained convection. Although low-level winds are fairly meager based on regional VWP and ACAR observations, 30-40 knot winds above 3 km should elongate hodographs sufficiently to support organized convection. Semi-discrete cells and clusters appear most probable given the unfocused forcing for ascent under the based of a mid-level trough, and should pose a threat for severe hail (most likely between 1.0 to 1.5 inches) and damaging winds - especially by late afternoon when low-level lapse rates will be greatest. The nebulous forcing for ascent casts some uncertainty onto overall storm coverage, which is supported by recent CAMs. Because of this, the spatial threat should remain focused to far eastern GA into southern/eastern SC. Watch issuance is not anticipated given this limitation. ..Moore/Hart.. 03/06/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ILM...CHS...CAE...FFC...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0157 PM CST Wed Mar 06 2024 Valid 062000Z - 071200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN SOUTH FL...SC...AND WEST-CENTRAL TO NORTH TX... ...SUMMARY... Isolated severe thunderstorms are possible through early evening over parts of south Florida and South Carolina, and from late afternoon into tonight over west-central to northeast Texas. ...20Z Update... Across the FL Peninsula and SC vicinity, severe potential appears limited through about 23Z before convection shifts off the Atlantic coast. Over TX, initial cumulus development in the Concho Valley should be the precursor to a couple storms by early evening. Primary outlook change was to expand a bit east-northeast across a portion of the Red River Valley. Recent RRFS and 12Z MPAS runs, along with observational trends support potential for isolated thunderstorm development near the slowly advancing warm front. Lower-end severe hail and strong wind gusts appear possible. ..Grams.. 03/06/2024 .PREV DISCUSSION... /ISSUED 1006 AM CST Wed Mar 06 2024/ ...FL... A warm/moist air mass is present across the central/southeast portions of the FL Peninsula today, where pockets of daytime heating will yield afternoon moderate MLCAPE values around 2000 J/kg. At least isolated thunderstorms are expected to form across this area during the afternoon, tracking slowly eastward toward the coast. Forecast soundings suggest low/deep layer shear is not particularly strong, but given the favorable thermodynamics, a few strong to briefly severe storms capable of hail and damaging winds will be possible - especially near the east coast. The severe threat should diminish after sunset. ...SC... Multiple weak shortwave troughs are rotating across the Carolinas today. One feature is currently over western GA, accompanied by a cluster of showers. This activity will move into SC this afternoon, where daytime heating will help to steepen low level lapse rates and lead to at least marginal CAPE values. Low level winds will be quite veered and relatively weak. However, a storm or two may be briefly intense with gusty winds or hail. ...TX... Clear skies will lead of strong heating and steepening lapse rates across west-central TX today. Most CAM solutions suggest one or two storms could form in the well-mixed zone near San Angelo late this afternoon. Steep mid-level lapse rates would support a risk of hail or damaging wind gusts in these storms. After dark, a strengthening southerly low-level jet would likely allow this activity to become more numerous and spread northeastward toward the Red River. The overall severe threat would likely weaken after dark, but could still pose a risk of occasional hail or gusty winds. Read more
