WW 490 SEVERE TSTM KS 141655Z - 150000Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 490 NWS Storm Prediction Center Norman OK 1155 AM CDT Fri Jul 14 2023 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southern and eastern Kansas * Effective this Friday morning and evening from 1155 AM until 700 PM CDT. * Primary threats include... Widespread damaging winds and scattered significant gusts to 85 mph likely Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible A tornado or two possible SUMMARY...A complex of severe storms will move rapidly southeast across the watch area this afternoon, with intense damaging wind gusts up to 85 mph expected. Large hail will also be possible with isolated supercell storms that develop in advance of the complex of storms. The risk for a tornado or two will exist, especially along the leading edge of storms with embedded bowing segments. The severe thunderstorm watch area is approximately along and 90 statute miles north and south of a line from 35 miles north of Dodge City KS to 50 miles east of Emporia KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 489... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 75 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 30040. ...Bunting Read more

MD 1550 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PARTS OF SOUTHERN/CENTRAL MN INTO NORTHWESTERN WI
Mesoscale Discussion 1550 NWS Storm Prediction Center Norman OK 0310 PM CDT Fri Jul 14 2023 Areas affected...Parts of southern/central MN into northwestern WI Concerning...Severe potential...Watch unlikely Valid 142010Z - 142245Z Probability of Watch Issuance...20 percent SUMMARY...A couple instances of marginally severe hail and locally damaging gusts are possible across parts of southern/central MN into northwestern WI into early evening. A watch is not expected. DISCUSSION...A few loosely organized thunderstorms are tracking eastward across parts of southwestern/south-central MN this afternoon -- generally focused along a NNE/SSW-oriented surface trough. Ahead of this activity, differential heating along the northern edge of widespread cloud coverage should provide a favorable corridor across parts of southern/central MN into northwestern WI for the maintenance of this activity into the early evening time frame. A plume of steep midlevel lapse rates across the area and an elongated/straight hodograph (around 30 kt of effective shear) could support marginal supercell structures and loosely organized clusters capable of producing marginally severe hail and locally damaging winds. Overall, the severe threat is expected to remain too marginal/isolated for a watch. ..Weinman/Bunting.. 07/14/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0251 PM CDT Fri Jul 14 2023 Valid 142000Z - 151200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER CENTRAL TO EASTERN KANSAS...WESTERN MISSOURI...AND NORTHERN OKLAHOMA... ...SUMMARY... Severe thunderstorms producing damaging winds, including some over 75 mph and large hail are forecast today over portions of the central and southern Plains. Isolated damaging gusts or marginal hail will also be possible over parts of the Mid Atlantic and southern New England, the Great Lakes, and the Mid-Mississippi Valley. ...KS/MO/OK... A substantial MCS is currently moving southeastward across central KS with additional activity extending east along I-70 into northeast KS. The air mass ahead of these storms remains strongly unstable with a warming air mass and 70s F dewpoints. Earlier, GBD measured a wind gust of 52 kt near the tail end of the MCS, with 63 kt measured at TOP and various KS mesonet locations over 60 mph. For more information see mesoscale discussion 1547. ...MN into WI... Heating near a surface trough with steep low-level lapse rates and sufficient instability may favor isolated hail or gusty winds, and a Marginal Risk has been added to this region, generally north of the existing cirrus canopy where heating is strongest. ..Jewell.. 07/14/2023 .PREV DISCUSSION... /ISSUED 1130 AM CDT Fri Jul 14 2023/ ...Central and southern Plains... An ongoing cluster of severe storms was located over southwest/south-central NE at 16z, with a history of large hail and, more recently, severe gusts. This small complex is within a zone of warm advection in the 850 to 700-mb layer, and will likely continue moving southeastward along an instability gradient this afternoon and evening. Aided by steep lapse rates in the midlevels and strong-locally extreme MLCAPE across central KS/central and eastern OK this afternoon, an expected evolution into a fast-moving MCS with significant severe wind gust potential is anticipated. The Enhanced Risk was expanded west over KS based on morning CAM guidance, and also adjusted slightly southward over OK. The Slight and Marginal Risk areas were also expanded south as well-organized and fast-moving MCSs often persist longer than reflected in some operational guidance. Given the CAPE-shear parameter space, supercell potential will also exist with this MCS and an attendant risk for large hail. Farther west, isolated supercell development appears possible across southeast WY/northeast CO late today, along the southern fringe of stronger WNW mid-level flow. Large hail will be possible. ...MO/IA/IL/WI... A cold front will move into parts of southern IA, northern MO, northwest IL, and southern WI by afternoon, and scattered thunderstorm development is expected in the vicinity of the front. Moderately strong westerly mid-level winds and ample CAPE will promote a few organized clusters capable of hail and damaging wind gusts for a few hours through this evening. ...East Coast from NC to New England... Diurnal heating of a moist air mass (dew points averaging upper 60s-mid 70s) will lead to moderate CAPE across a rather large area this afternoon. A weak shortwave trough will approach the mid-Atlantic states this afternoon, contributing to the development of widely scattered thunderstorms from NC across the Mid-Atlantic into southern New England. Winds aloft will be relatively weak (25-30 knots), but the potential will exist for a few slow-moving multicell clusters capable of gusty/damaging winds this afternoon and early evening. Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0243 PM CDT Fri Jul 14 2023 Valid 151200Z - 161200Z ...NO CRITICAL AREAS... The previous forecast remains on track. See the discussion below for more details. ..Karstens.. 07/14/2023 .PREV DISCUSSION... /ISSUED 1218 AM CDT Fri Jul 14 2023/ ...Synopsis... The western upper-level ridge will undergo some amplification on Saturday. Late Saturday into Sunday morning, a shortwave trough is expected to being moving into the Northwest. At the surface, the high pressure system in the intermountain region will generally remain in place. Fire weather concerns are again expected to be minimal for most locations. Some enhancement to the northwesterly mid-level winds is possible in the eastern Great Basin and Four Corners. Locally elevated conditions will be possible during the afternoon. The strengthening winds aloft over the Northwest will not be favorably timed for fire weather concerns. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1223 PM CDT Fri Jul 14 2023 Valid 151200Z - 161200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER MUCH OF THE LOWER GREAT LAKES...OHIO AND TENNESSEE VALLEY REGIONS...AND OVER THE SOUTHERN HIGH PLAINS... ...SUMMARY... Scattered storms, a few producing damaging gusts, are possible from the Lower Great Lakes across parts of the Ohio and Tennessee Valleys toward the southern Appalachians. Isolated hail is also possible late over the southern High Plains. ...Synopsis... A deep upper low will remain over the Manitoba/Ontario area with a broad area of cyclonic flow aloft over the northern Plains, Great Lakes and Northeast. The southern periphery of the stronger flow aloft will sweep east across the OH and TN Valleys during the day, with a wave ejecting northeastward toward the Mid Atlantic overnight. Winds around 850 mb will increase out of the south late in the day and overnight ahead of the upper wave, enhancing warm/moist advection and lift. At the surface, a cold front will stretch roughly from OH into TN by late afternoon, with dewpoints near 70 F. A warm front will also lift northward overnight across PA and NY, aided by the stronger flow off the surface. A surface low will develop over OH, and will deepen a bit overnight into western NY. ...Lower Great Lakes southward into northern AL/GA/SC... A morning MCS may affects parts of southern MO, western TN and KY Saturday morning, and may provide a further focus for redevelopment during the day and during the evening across TN, northern AL and GA. Predictability is low for this scenario but ample moisture and instability will be present to support a conditional wind threat in this corridor, possibly extending into the western Carolinas overnight. During the day, areas of rain and storms will exist in association with the upper trough and cold front, moving across IN, OH, KY, with stronger activity possible during the diurnal cycle over OH and eastern KY. Locally strong gusts or marginal hail will be possible but neither CAPE nor shear will be very strong. During the evening, low-level shear will increase as the low deepens and winds just off the surface increase to over 30 kt. This will increase SRH, but at a time when low-level instability will be minimized. Still, rising dewpoints may yield SBCAPE sufficient for a few ongoing cells to acquire rotation, with either enhanced wind gust potential or a brief/weak tornado. ...Southeast CO...eastern NM...western TX Panhandle... Low-level moisture will surge northwestward during the evening and overnight from the TX Panhandle into NM and southeast CO, where a steep lapse rate environment will remain. A few elevated cells capable of large hail are forecast mainly after 03Z, moving southeastward out of CO/NM and into the TX Panhandle through Sunday morning. ..Jewell.. 07/14/2023 Read more

Watch issuance is possible. DISCUSSION...A cluster of strong to severe thunderstorms has recently developed across eastern SD, with several reports of severe hail in the last hour. Moderate buoyancy and unidirectional wind profiles with around 30-40 kt of effective shear are supporting occasional supercell structures, and some hail threat may continue as storms approach southwest MN, where a similar environment is in place. Farther north, strong to potentially severe storms are moving from eastern ND into western MN, and may pose a localized hail threat in the short term. With time, some clustering and modest upscale growth of convection is possible. While relatively dry conditions are noted across parts of central MN, steep low/midlevel lapse rates could support some damaging wind threat with any upscale growing cluster by early evening. Watch issuance is possible for some portion of western/central MN, depending on short-term observational trends. ..Dean/Guyer.. 07/13/2023 ...Please see www.spc.noaa.gov for graphic product...
