Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1253 AM CDT Wed Sep 11 2019 Valid 111200Z - 121200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER MUCH OF WESTERN NEBRASKA...AND SMALL ADJACENT PARTS OF WYOMING AND COLORADO... ...SUMMARY... Severe thunderstorms capable of producing large hail, damaging wind gusts, and a tornado or two are possible mainly over parts of the central and northern Plains. More isolated and/or marginal severe storms are possible extending eastward across the southern Great Lakes and to the East Coast from Virginia to New Jersey. ...Synopsis... A shortwave trough will progress east across the Rockies, with a 50-60 kt midlevel speed max moving from the central High Plains during the day to the central Plains by Thursday morning. Modest westerly winds aloft will extend across the Great Lakes, north of a gradually weakening upper high over the Southeast. At the surface, low pressure will move from northeast CO across NE, with a stationary front roughly from northern NE, IA and into southern WI. Early day storms and outflow may change the position of this front. During the evening and overnight, a cold front will move east across the central Plains behind the low. Dewpoints in the 65-70 F range will be common south of the stationary front and ahead of the cold front, aiding the development of ample instability supporting strong to severe storms from eastern WY into southern WI. ...Eastern WY...far northeast CO...NE... An outflow boundary now over west-central NE and northeast CO is expected to mix during the day, and may retreat north as southerly winds increase ahead of the upper trough. Heating south of the outflow (and ahead of the developing cold front over eastern WY) along with ample moisture will lead to strong instability. Low-level winds will veer with height, but will remain relatively weak below 700 mb resulting in long, mostly straight hodographs as the upper jet overspreads the High Plains. Storms are expected to form over eastern WY by early afternoon, and over northeast CO and western NE near a triple point. Supercells capable of very large hail will be possible, with perhaps brief tornadoes although effective SRH will average 100-150 m2/s2 prior to 00Z. Thereafter, storms are expected to merge into an MCS with damaging wind the main concern. ...Upper MS Valley and Great Lakes... Storms may be ongoing early in the day as an MCS (now over SD/MN/IA) continues east along the instability gradient. Southwest winds at 850 mb will also maintain warm/moist advection into the region, supporting continued development or rejuvenation of the pre-existing system. Damaging winds appears to be the main concern. ...PA and NJ southwestward into northern GA... Although beneath an upper ridge, the air mass will remain moist and the region will experience strong heating. MLCAPE of 2000-3000 J/kg will develop, and will conditionally favor pulse storms capable of marginally severe wind or hail over the Appalachians. Storm mode over northern areas such as PA and NJ may trend toward multicells with 20-30 kt mid to high-level flow. The severe threat will be tied to the diurnal cycle, and will dwindle by early evening. ..Jewell/Squitieri.. 09/11/2019 Read more

MD 1953 CONCERNING SEVERE THUNDERSTORM WATCH 643... FOR PARTS OF SOUTHEASTERN SOUTH DAKOTA...SOUTHWESTERN MINNESOTA...NORTHEASTERN NEBRASKA...NORTHWESTERN IOWA
Mesoscale Discussion 1953 NWS Storm Prediction Center Norman OK 1131 PM CDT Tue Sep 10 2019 Areas affected...Parts of southeastern South Dakota...southwestern Minnesota...northeastern Nebraska...northwestern Iowa Concerning...Severe Thunderstorm Watch 643... Valid 110431Z - 110600Z The severe weather threat for Severe Thunderstorm Watch 643 continues. SUMMARY...An evolving cluster of storms may continue to pose a risk for strong surface gusts east of Sioux Falls SD, near the western Minnesota/Iowa border area through 1-2 AM CDT. It is not certain that a new severe weather watch will be needed farther east, but trends will continue to be monitored for this possibility. DISCUSSION...Vigorous thunderstorm development persists, southeast and south of a lower/mid tropospheric cyclonic vorticity center which has become increasingly evident in radar imagery, currently east of Mitchell SD. This is also near the nose of a strengthening and gradually veering southerly low-level jet (40-50 kt at 850 mb), but generally to the cool side of the effective warm frontal zone (across southeastern South Dakota) and a southeastward advancing outflow boundary (across north central Nebraska). Low-level shear is strong ahead of the convective outflow across southeastern South Dakota, where modest near surface easterlies veer to southerly and southwesterly aloft. However, north of the surface front, near surface thermodynamic profiles are cool and stable to surface-based convection. The risk for tornadoes appears low, but the environment may be conducive to strong surface gusts as activity spreads east of the Sioux Falls area, near the western Minnesota/Iowa border area through 06-07Z. This leading convection has been advancing eastward roughly with the modest 20-30 kt westerly deep-layer ambient mean flow, but some eastward acceleration is possible during the next couple of hours. ..Kerr.. 09/11/2019 ...Please see www.spc.noaa.gov for graphic product...
