MD 1411 CONCERNING SEVERE THUNDERSTORM WATCH 439...440... FOR PORTION OF THE MID-ATLANTIC
Mesoscale Discussion 1411 NWS Storm Prediction Center Norman OK 0349 PM CDT Mon Jul 03 2023 Areas affected...Portion of the Mid-Atlantic Concerning...Severe Thunderstorm Watch 439...440... Valid 032049Z - 032245Z The severe weather threat for Severe Thunderstorm Watch 439, 440 continues. SUMMARY...Damaging winds will continue to be possible across much of the Mid-Atlantic the remainder of this afternoon. There remains some potential for convection within the northern Blue Ridge to intensify as it moves east. DISCUSSION...The strongest storms within the Mid-Atlantic region have been in the Virginia Beach, VA vicinity into northeast North Carolina. The organized cluster of storms there have produced wind damage reports. This activity may move offshore in the next 1-2 hours. Convection has been more isolated in central Virginia, but MRMS radar has shown strong cores with some of these storms as they move eastward. The current activity will continue to pose a threat of damaging winds given the strong surface heating and steep low-level lapse rates. Earlier cloud cover has hindered convective development along northern portions of the Blue Ridge. As this cloud cover has dissipated, cumulus has become deeper in far northern Virginia/central Maryland. The moist airmass downstream will continue to destabilize over the next couple of hours. As such, eastern portions of Maryland into southern New Jersey should eventually get impacted by intensifying storms from the northern Blue Ridge along with storms moving in from central Virginia. ..Wendt.. 07/03/2023 ...Please see www.spc.noaa.gov for graphic product...

MD 1410 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF NORTHEASTERN NE...SOUTHEASTERN SD...SOUTHWESTERN MN...AND NORTHWESTERN IA
Mesoscale Discussion 1410 NWS Storm Prediction Center Norman OK 0348 PM CDT Mon Jul 03 2023 Areas affected...portions of northeastern NE...southeastern SD...southwestern MN...and northwestern IA Concerning...Severe potential...Watch unlikely Valid 032048Z - 032245Z Probability of Watch Issuance...20 percent SUMMARY...Scattered thunderstorms are expected during the next few hours. Local wind gusts and small hail are possible. Watch issuance is not anticipated. DISCUSSION...Several thunderstorms have developed along a cold front draped from south-central MN west-southwestward along the SD/NE border. The front continues to slowly sag southward, with the environment along and ahead of it generally characterized by MLCAPE around 2000+ J/kg and effective shear around 15 kts. Current VAD and short-term forecast profiles depict modest low-level shear with little shear above the boundary layer. While the primary belt of mid-level flow resides farther north, sufficient boundary-layer mixing should support continued updraft development and maturation through the afternoon. Multicell/pulse evolution is expected given the overall meager kinematic environment. Steep mid-level lapse rates and relatively high cloud bases might support local gusty winds and small hail prior to a general weakening trend closer to sunset. ..Flournoy/Grams.. 07/03/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0243 PM CDT Mon Jul 03 2023 Valid 032000Z - 041200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS NORTHEAST WY/WESTERN SD AND THE MID-ATLANTIC STATES... ...SUMMARY... A swath of severe wind gusts from 60-80 mph and isolated very large hail are probable across a portion of northeast Wyoming into western South Dakota this evening. Scattered damaging winds from strong to isolated severe gusts are likely across parts of the Mid-Atlantic States through early evening. ...Discussion... No appreciable changes were made to the previous convective outlook. ..Smith.. 07/03/2023 .PREV DISCUSSION... /ISSUED 1130 AM CDT Mon Jul 03 2023/ ...Lee of the Big Horns through SD... A shortwave trough over the northern Rockies will shift east and yield a strengthening mid-level speed max across eastern MT by this evening. Trailing portion of a cold front will become quasi-stationary across southern SD with post-frontal upslope flow expected over the Big Horns and Black Hills. A plume of enhanced low-level moisture near/north of the front in conjunction with steep mid-level lapse rates will support a corridor of MLCAPE from 1500-2500 J/kg. With weak low-level easterlies beneath the strengthening mid-level westerlies, hodographs should become quite elongated and nearly straight, yielding at least a few supercells with left/right-splits. Isolated very large hail is expected initially. The strong forcing for ascent and cold pool consolidation may result in a small MCS with potential for bowing structures centered on the western SD vicinity this evening. This would likely yield an increased severe wind threat of 60-80 mph gusts. Increasing MLCIN after sunset in conjunction with the narrowness of the buoyancy plume should yield a relatively confined swath/more isolated severe wind threat overnight into eastern SD. ...Mid-Atlantic States A slowly weakening mid-level trough over the Lower Great Lakes will gradually progress across the Northeast through tonight. Differential boundary-layer heating across a lee trough along the central to southern Appalachians will be the focus for scattered thunderstorms this afternoon. A belt of enhanced 35-45 kt west-southwesterlies was sampled at 2-5 km MSL in 12Z soundings across VA to the DE Valley. While this flow regime will slowly subside/shift east through the day, it will remain favorable for widely spaced multicell clusters that evolve into short-line segments spreading east towards the coast. Hodographs will be relatively straight and modestly elongated, especially with northern extent, but mid-level lapse rates will remain weak. This suggests severe hail will probably remain isolated, but even small hail should help to enhance water-loaded downdrafts. Multiple swaths of at least scattered damaging winds are likely through early evening. ...Deep South to OK... Remnants of a weakening cold front will serve as an effective surface trough/boundary-layer moisture gradient arcing west from the TN Valley to an MCV over western OK. Scattered thunderstorms are expected along this arc during the afternoon with moderately large buoyancy characterized by MLCAPE of 2000-3000 J/kg. Despite weak vertical shear, water-loaded downdrafts will support sporadic damaging winds through about dusk. ...MN vicinity... Scattered thunderstorms will develop along a cold front from northeast to southwest MN this afternoon. Deep-layer vertical shear will be rather weak, as the front remains displaced well east of stronger mid-level flow attendant to the SK/MB upper low. But large buoyancy with MLCAPE of 2500-3500 J/kg will support pulse to weakly congealing clusters along the front with primary threats of sporadic microbursts and hail. ...Central Rockies to northern Great Basin... Isolated to scattered high-based thunderstorm development is expected this afternoon. Inverted-V profiles with modest CAPE and large DCAPE, in combination with the southern periphery of 25-40 kt mid-level flow, will support the potential for at least isolated strong-severe outflow gusts of 55-70 mph.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1232 PM CDT Mon Jul 03 2023 Valid 041200Z - 051200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NORTHERN ARIZONA... The previous forecast (see below) remains generally on track. The main changes to the Day 2 Fire Weather Outlook Update were to expand Elevated highlights northeast into southwestern Colorado and add isolated dry thunderstorm highlights. Here, fuels are quickly curing and becoming receptive to wildfire spread. Latest guidance consensus depicts 15+ mph sustained west-southwesterly surface winds overlapping with 10-15 percent RH, warranting the northeastward expansion of Elevated highlights. Furthermore, high-based, relatively fast-moving thunderstorms developing off of the higher terrain in western Colorado will foster dry lightning potential during the afternoon hours. Lightning-induced fire ignitions may be further exacerbated by gusty and erratic thunderstorm winds, some of which may approach severe criteria. Please see the Day 2 Convective Outlook for more details pertaining to the severe thunderstorm threat. ..Squitieri.. 07/03/2023 .PREV DISCUSSION... /ISSUED 0200 AM CDT Mon Jul 03 2023/ ...Synopsis... Midlevel troughing accompanied by strengthening west-southwesterly flow aloft will develop over parts of the Southwest and Great Basin -- where a warm/dry antecedent air mass is in place. As the boundary layer deepens into the enhanced flow aloft, and the pressure gradient tightens in response to a developing surface low over the Four Corners region, 20 mph sustained west-southwesterly surface winds (with higher gusts) will overspread parts of northern AZ. These winds, coupled with widespread 10 percent minimum RH, will yield critical fire-weather conditions given increasingly dry fuels across the region. Additionally, locally elevated fire-weather conditions will continue across parts of southern CA away from the immediate coast, as onshore flow persists over the area. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Mon Jul 03 2023 Valid 041200Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS NORTHERN KANSAS AND SOUTHERN NEBRASKA... ...SUMMARY... Scattered severe thunderstorms are forecast over central Great Plains beginning late afternoon Tuesday into Tuesday night. Severe thunderstorm gusts will be the primary hazard. ...Synopsis... A weak upper trough is forecast to shift slowly eastward across New England Tuesday, while farther west, a more pronounced area of cyclonic flow will continue to expand across portions of the Intermountain West and northern/central Plains area. At the surface, a weak front will linger across the East Coast and Gulf Coast states, while a stronger cold front will move east across the Upper Midwest southwestward through portions of the central High Plains. ...Upper MS Valley southwestward to the central High Plains... Isolated to scattered showers/thunderstorms will probably be ongoing across the Upper Midwest near/behind the front during the morning. This early day activity will likely weaken with moderate destabilization forecast on the periphery of any morning convective outflow ahead of the front. A slowly advancing, northeast-to-southwest cold front will be the focus for renewed thunderstorm activity during the afternoon. While stronger flow aloft will remain to the west of the Upper Mississippi to Mid-Missouri Valley portion of the front, multicell storm clusters evolving with time will pose risk for locally damaging winds and hail. Farther to the southwest, into the central High Plains, easterly upslope flow just to the cool side of the front beneath 20 to 35 kt 500-mb westerlies will yield shear supporting a mix of supercells and multicells. Thunderstorms will likely develop near the higher terrain of the Colorado Front Range/higher terrain of southeast Wyoming by early afternoon. This convection will gradually push east into the adjacent High Plains by mid-late afternoon with a corresponding increase in storm coverage. Concurrently, weakening convective inhibition due to strong heating near the front over NE will lead to scattered thunderstorms developing by late afternoon over the Nebraska Sandhills. Forecast soundings show very steep surface-400 mb lapse rates (8+ deg C/km) ahead of the front. The latest model guidance suggests increasing storm coverage by early evening with several clusters evolving from northeast Colorado into northwest Kansas and a separate adjacent area over southwest into central Nebraska. Both regimes may merge during the evening with severe gusts being the primary hazard, including the possibility of peak gusts 70-85 mph. This notion of significant severe gusts seems supported by some of the latest CAM guidance. This severe cluster/MCS will push east near the Kansas/Nebraska border during the overnight with a gradual weakening trend expected. ...Portions of the East Coast Region and Southeast into north TX... Diurnal heating/destabilization near and ahead of the weak/slow-moving front extending southwestward across the Eastern Seaboard, and westward across the southeast will result in scattered thunderstorm development. While modest deep-layer shear suggests generally disorganized convection, moderate west-southwesterlies through the lower and middle troposphere may promote a few eastward-propagating clusters of storms, where potential for strong/gusty outflow winds may be relatively maximized. Overall however, hail/wind potential should remain isolated, confined to generally disorganized storms into the evening hours. Have added low-severe probabilities westward into the southern Great Plains to account for at least isolated thunderstorms developing during the late afternoon/early evening. A more deeply mixed profile compared to farther east (Mississippi/Alabama) may foster isolated severe gusts and perhaps marginally severe hail with the more intense storms. ..Smith.. 07/03/2023 Read more

MD 1392 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PARTS OF EASTERN TN...WESTERN AND CENTRAL NC...NORTHWESTERN SC...AND FAR SOUTHWESTERN VA
Mesoscale Discussion 1392 NWS Storm Prediction Center Norman OK 0454 PM CDT Sun Jul 02 2023 Areas affected...Parts of eastern TN...western and central NC...northwestern SC...and far southwestern VA Concerning...Severe potential...Watch possible Valid 022154Z - 022330Z Probability of Watch Issuance...60 percent SUMMARY...The severe risk will continue to increase through the early evening, and a watch may be needed for parts of the area within the hour. DISCUSSION...Latest visible satellite imagery shows an increasingly agitated boundary-layer cumulus field over parts of western NC this afternoon -- where a warm and moist air mass is in place (lower 90s temperatures and lower 70s dewpoints). Current thinking is that continued diurnal destabilization along with orographic ascent will support isolated to widely scattered thunderstorms through the early evening. The MRX VWP sampled a west-southwesterly, unidirectional wind profile with around 30-40 kt of effective shear. This wind profile, coupled with the destabilizing air mass, should support a mix of organized multicells and transient supercells capable of wind damage and marginally severe hail. A watch may be needed within the hour for parts of the area. ..Weinman/Hart.. 07/02/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...RAH...RNK...CAE...GSP...MRX...FFC...
