SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1148 PM CDT Wed Aug 07 2019 Valid 081200Z - 091200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE OHIO VALLEY INTO CENTRAL NEW YORK AND PENNSYLVANIA... ...SUMMARY... Areas of hail and strong wind gusts are likely from the Ohio Valley eastward into central New York and Pennsylvania. Isolated severe hail is possible across parts of the High Plains. ...Synopsis... A broad area of cyclonic flow aloft will stretch from the upper MS Valley across the Great Lakes and the Northeast. A leading wave will move across New England during the day, with a secondary stronger wave moving into western NY and PA by 00Z. A cold front will progress across Lakes Ontario and Erie by 18Z, and will trail westward across central OH and IN. Ahead of the front, widespread low to mid 60s F dewpoints will exist beneath cool profiles aloft supporting strong to locally severe storms. To the west, an upper ridge will exist over the Rockies, with northwest flow over the Plains. A weak area of low pressure will exist over the TX Panhandle and western OK, with a stationary front extending eastward over northern OK or near the KS border. Ample low-level moisture will exist over the central Plains, with easterly winds north of the front aiding destabilization across the High Plains late in the day. ...OH Valley into the Northeast... An arcing line of storms is likely to develop by 18Z from western NY into northwest PA along the cold front, with additional development westward into OH and IN later in the afternoon. Northwest flow aloft will have a large component perpendicular to the boundary, with strong winds in the upper levels. This suggests the dominant storm mode will be cellular, with large hail likely. Little low-level shear/SRH suggests very low tornado risk, though damaging winds will be possible as storms form during peak heating with steep boundary layer lapse rates and 25-30 kt westerly 850 mb winds. ...Central and northern High Plains and northern Oklahoma into southern Kansas... Strong heating will occur beneath the upper ridge, while easterly surface winds maintain 50s dewpoints into eastern WY and CO. This will support afternoon development over the higher terrain, with activity slowly moving eastward through evening. Weak low-level winds beneath modest mid to upper flow will support a few slow-moving cells or propagating outflows, with marginal hail or wind will be possible. To the east into OK and KS, convection is likely to be ongoing early in the day north of the front from KS into western MO in a warm advection regime. Heating will occur upstream across TX and OK, resulting in areas of strong instability. New development is likely during the late afternoon and evening along the east-west front, with locally severe wind gusts or hail possible. ..Jewell/Cook.. 08/08/2019 Read more

MD 1672 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHERN SD...NORTHERN NE
Mesoscale Discussion 1672 NWS Storm Prediction Center Norman OK 1113 PM CDT Wed Aug 07 2019 Areas affected...Southern SD...Northern NE Concerning...Severe potential...Watch unlikely Valid 080413Z - 080545Z Probability of Watch Issuance...20 percent SUMMARY...Some hail threat, along with gusty winds, are possible with storms along the SD/NE border region for the next several hours. Severe thunderstorm watch is not anticipated. DISCUSSION...Weak warm advection appears mostly responsible for recent elevated convection along the SD/NE border. This activity is developing just north of a weak front that is sagging slowly south across the central Plains. Forecast soundings across the central Plains exhibit more than adequate cloud-layer shear for sustained updrafts; however, forecast hail algorithm is not particularly aggressive with with values generally on the order of 1" or less. Even so, hail likely accompanies more organized supercells. Will continue to monitor this region but it remains unclear whether this activity will achieve sustained severe levels warranting a severe thunderstorm watch. ..Darrow/Hart.. 08/08/2019 ...Please see www.spc.noaa.gov for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Wed Aug 07 2019 Valid 080100Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL PLAINS... ...SUMMARY... Scattered storms are expected tonight across parts of the Central Plains, with hail or wind possible. Otherwise, a decreasing severe threat is expected across the Great Lakes, Mid Atlantic, and Lower Mississippi Valley where isolated strong wind gusts remain possible. ...Central Plains... A moist and unstable air mass remains over much of the central states, with sporadic storms across many states. One possible corridor of focused severe threat is expected to develop along and north of a stationary front extending from eastern CO across KS and into southwest MO. Southwesterly 850 mb winds are expected to increase tonight, which will increase warm advection near this boundary. The steep lapse rate environment beneath modest northwest flow aloft should support scattered storms in a northwest-southeast zone along the front, with hail and locally damaging wind gusts possible. ...WI.. Cooler and drier air will continue to surge across WI behind a cold front, and will continue to support scattered thunderstorms. The instability axis currently extends northeastward out of IA and into WI, and this is where isolated marginally severe storms are possible. A weakening trend is expected with the loss of heating, thus the threat may only exist for a couple hours. ..Jewell.. 08/08/2019 Read more

MD 1671 CONCERNING SEVERE THUNDERSTORM WATCH 560... FOR EASTERN NORTH CAROLINA...A SMALL PART OF NORTHEASTERN VIRGINIA
Mesoscale Discussion 1671 NWS Storm Prediction Center Norman OK 0615 PM CDT Wed Aug 07 2019 Areas affected...eastern North Carolina...a small part of northeastern Virginia Concerning...Severe Thunderstorm Watch 560... Valid 072315Z - 080015Z The severe weather threat for Severe Thunderstorm Watch 560 continues. SUMMARY...A lingering, isolated severe threat exists, although the majority of the severe threat has diminished across WW 560. DISCUSSION...A loosely organized band of storms continues to persist along and ahead of an outflow/mature cold pool moving through eastern North Carolina. Though moderate instability remains in place along and ahead of the band of storms, weak low-level shear was continuing to support limited organization and outflow-dominant activity containing mostly sub-severe wind gusts. Still, an isolated severe gust will remain possible over the next hour or so as storms forward-propagate toward the Outer Banks. Farther north, a very isolated severe threat will remain across northeastern Virginia along a slowly southward-moving outflow between LKU and EZF. A spatially focused pocket of instability remains in place in this region - which has mainly been unaffected by more substantial convective overturning to the east. This threat is not sufficient to necessitate a continued WW, though wind/tree damage cannot be completely ruled out. ..Cook.. 08/07/2019 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1670 NWS Storm Prediction Center Norman OK 0556 PM CDT Wed Aug 07 2019 Areas affected...eastern Maryland...Delaware...New Jersey...eastern and southern New York...Connecticut...Massachusetts...southern New Hampshire...and southern Vermont Concerning...Severe Thunderstorm Watch 561... Valid 072256Z - 080000Z The severe weather threat for Severe Thunderstorm Watch 561 continues. SUMMARY...The severe threat continues across remaining portions of WW 561. Clearing of the Watch behind an extensive band of storms entering the discussion area may continue. DISCUSSION...Storms have gradually grown upscale into convective bands across the southern half of the discussion area (from near Long Island, NY southwestward through Delaware), with more scattered convection located across southern New England and east-central New York. These storms remain in a moderately unstable pre-convective environment characterized by 2000-3000 J/kg MUCAPE, with modest shear resulting in mostly outflow-dominant storms. Damaging wind are the main threats, though isolated instances of large hail cannot be ruled out. West of these storms, convective overturning has lowered the severe threat, and these portions of WW 561 have been canceled early. As storms approach open waters of the far northwestern Atlantic, additional clearing will likely be needed. ..Cook.. 08/07/2019 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1668 NWS Storm Prediction Center Norman OK 0257 PM CDT Wed Aug 07 2019 Areas affected...the Mid-Atlantic into portions of the Northeast Concerning...Severe Thunderstorm Watch 561... Valid 071957Z - 072130Z The severe weather threat for Severe Thunderstorm Watch 561 continues. SUMMARY...The severe weather threat continues in watch 561. Damaging winds and large hail are the primary threats. DISCUSSION...Numerous storms and storm clusters have developed from northern Virginia northeastward to southern Vermont and New Hampshire. These storms have produced numerous wind damage reports up to this point with a measured severe wind gust of 59 mph in Delaware and 63 mph in Massachusetts. There have been no severe hail reports up to this point which is likely due to the hot lower-tropospheric airmass. However, some MESH cores have suggested hail to near 1 inch, so would still anticipate at least an isolated severe hail threat to continue into the evening. The greatest severe weather threat will likely be in southeast New York and New Jersey for the next 1 to 2 hours where instability and storm coverage is greatest, and mid-level winds have increased to 45 to 50 knots (per DOX/DIX/OKX VWP). ..Bentley.. 08/07/2019 ...Please see www.spc.noaa.gov for graphic product...
