MD 1338 CONCERNING TORNADO WATCH 437... FOR DEEP SOUTH TEXAS
Mesoscale Discussion 1338 NWS Storm Prediction Center Norman OK 1144 PM CDT Wed Jun 19 2024 Areas affected...Deep South Texas Concerning...Tornado Watch 437... Valid 200444Z - 200645Z The severe weather threat for Tornado Watch 437 continues. SUMMARY...Occasionally strengthening showers and thunderstorms may continue to be accompanied by potential for a brief, weak tornado into the 1-3 AM CDT time frame. DISCUSSION...As Alberto slowly progresses toward the Mexican Gulf coast, a broad belt of moderately strong cyclonic easterly low-level flow (including 40-50 kt around 850 mb) will likely be maintained to its north, across and inland of Deep South Texas coastal areas into the overnight hours. Beneath this regime, moderately large clockwise-curved low-level hodographs may be maintained at least several more hours. Coupled with the potential for appreciable upward vertical motion within the lowest couple of kilometers above ground level, aided by the instability associated with a tropical moist boundary layer (including upper 70s to near 80F surface dew points), this will continue to contribute to an environment supportive of occasionally intensifying low-level mesocyclones within scattered inland progressing convection. ..Kerr.. 06/20/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1244 AM CDT Thu Jun 20 2024 Valid 211200Z - 221200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE NORTHERN PLAINS... ...SUMMARY... Scattered strong to severe storms will be possible from the northern High Plains into the upper Mississippi Valley on Friday, with a few strong storms over parts of the Northeast. A few severe gusts are also possible over parts of the eastern Great Basin. ...Synopsis... On Friday, and upper high will be centered over the OH/TN Valleys, and will gradually build westward across the southern Plains. To the north, the tail end of a broad, low-amplitude trough over eastern Canada will skirt the Great Lakes and Northeast, with 30-50 kt midlevel winds and slight cooling aloft. Farther west, the upper trough over the Great Basin will eject into the Rockies by 00Z, and amplify Friday night as it moves into the northern Plains enhancing large-scale ascent. Steep lapse rates and over parts of the Four Corners states will favor strong gusts with storms. At the surface, high pressure will extend from the mid MS Valley to the Mid Atlantic, with southerly winds across the Plains. Low pressure will develop over the central High Plains, and will move into SD overnight. A warm front will extend east of the low, across northern NE and into southern MN/WI Friday morning, moving north into SD and central MN by Saturday morning. The combination of increasing lift and moisture advection will favor areas of strong to severe storms mainly over far eastern WY, SD, MN, and parts of NE. To the east, a weak surface trough will remain from the lower Great Lakes into parts of the Northeast, again providing a focus for scattered daytime storms as the air mass remains unstable. ...Northern High Plains to the upper MS Valley... Early day thunderstorms are expected over southern parts of MN and perhaps into WI, north of the warm front. Lapse rates appear to be poor at that time, with minimal hail potential. However, as the warmer air lifts north, storms along the zone from northeast SD across southern MN see an uptick in storm intensity with hail threat initially. With time, and as the low develops, an MCS will be possible, with risk of damaging winds. Farther to the southwest, diurnal storms will form over the high terrain of eastern WY into north-central CO, and likely produce hail and wind as they move across western and into central NE. Ample instability will remain overnight ahead of High Plains activity to support a hail and wind risk as it persists all night across SD and into MN. ...Lower Great Lakes into the Northeast... A moist air mass and heating will again result in several daytime thunderstorms over the area, from eastern OH into southern New England. Forecast soundings indicate perhaps poorer midlevel lapse rates overall compared to the previous day, with more of a subsidence inversion around 700 mb. However, heating will easily support at least isolated development by early afternoon along the weak front. Isolated to scattered strong to damaging gusts will be the primary concern. ...UT...northern AZ...western CO into WY... Thunderstorm probabilities will be quite high on Friday over this region, owing to cool air aloft with the upper trough and plentiful midlevel moisture with PWAT of 0.75-1.00 inches. This should favor scattered afternoon development over a large area, with strong to severe outflows possible. ..Jewell.. 06/20/2024 Read more

Storms may produce scattered damaging gusts over parts of the Northeast on Thursday. Scattered severe storms are also expected over parts of the central High Plains. ...Northeast... Upper anticyclone currently centered over the middle Atlantic will gradually build west across the CONUS during the day1 period. As this occurs, some flattening of the height field is expected over southern QC into New England. Modest 500mb flow will extend along the international border, but much weaker mid-level winds will be noted over the lower Great Lakes into southern New England. This stronger flow over Canada will encourage a surface cold front to advance south into northern ME, arcing west along the international border into southern lower MI by 18z, with subsequent southeast movement expected across the Northeast into the early evening. This boundary will serve as the focus for convection later today as surface temperatures quickly soar through the 80s into the lower 90s. Additionally, while deep-layer shear will not be particularly strong along the northern fringe of the upper High, PW values are seasonally moist with 1.5-2 inches expected south of the frontal zone. Damaging winds are the primary risk with convection today. ...Central High Plains... Weak 12hr mid-level height rises are forecast across much of the interior western US through early evening as an upper trough repositions itself from WA/OR into CA. This will ensure a corridor of modest southwesterly flow at mid-levels from the Four Corners region into the central High Plains. Within this flow a few weak disturbances may track across the central Rockies into the Plains. Each of these features could encourage robust convection. Latest guidance suggests a weak lee cyclone will evolve over northeast CO by late afternoon in response to one of these features. LLJ is also forecast to respond across western KS into SD. As a result, an easterly boundary-layer component will be noted across the NE Panhandle into eastern WY. NAM forecast sounding for CYS at 22z exhibits negligible inhibition but MLCAPE on the order of 2000 J/kg with 35kt surface-6km bulk shear. HREF guidance strongly suggests convection will evolve over the higher terrain of south-central WY/CO fairly early, then propagate downstream, growing upscale into a possible MCS within the warm-advection zone. Convection should advance into the central Plains after sunset aided by strengthening LLJ. Initial storm mode should be supercellular and large hail is expected. Severe wind gusts could materialize along the leading edge of the MCS if it matures as expected. ..Darrow/Thornton.. 06/20/2024 Read more

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1252 AM CDT Thu Jun 20 2024 Valid 201200Z - 211200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE NORTHEAST AND OVER THE CENTRAL HIGH PLAINS... ...SUMMARY... Storms may produce scattered damaging gusts over parts of the Northeast on Thursday. Scattered severe storms are also expected over parts of the central High Plains. ...Northeast... Upper anticyclone currently centered over the middle Atlantic will gradually build west across the CONUS during the day1 period. As this occurs, some flattening of the height field is expected over southern QC into New England. Modest 500mb flow will extend along the international border, but much weaker mid-level winds will be noted over the lower Great Lakes into southern New England. This stronger flow over Canada will encourage a surface cold front to advance south into northern ME, arcing west along the international border into southern lower MI by 18z, with subsequent southeast movement expected across the Northeast into the early evening. This boundary will serve as the focus for convection later today as surface temperatures quickly soar through the 80s into the lower 90s. Additionally, while deep-layer shear will not be particularly strong along the northern fringe of the upper High, PW values are seasonally moist with 1.5-2 inches expected south of the frontal zone. Damaging winds are the primary risk with convection today. ...Central High Plains... Weak 12hr mid-level height rises are forecast across much of the interior western US through early evening as an upper trough repositions itself from WA/OR into CA. This will ensure a corridor of modest southwesterly flow at mid-levels from the Four Corners region into the central High Plains. Within this flow a few weak disturbances may track across the central Rockies into the Plains. Each of these features could encourage robust convection. Latest guidance suggests a weak lee cyclone will evolve over northeast CO by late afternoon in response to one of these features. LLJ is also forecast to respond across western KS into SD. As a result, an easterly boundary-layer component will be noted across the NE Panhandle into eastern WY. NAM forecast sounding for CYS at 22z exhibits negligible inhibition but MLCAPE on the order of 2000 J/kg with 35kt surface-6km bulk shear. HREF guidance strongly suggests convection will evolve over the higher terrain of south-central WY/CO fairly early, then propagate downstream, growing upscale into a possible MCS within the warm-advection zone. Convection should advance into the central Plains after sunset aided by strengthening LLJ. Initial storm mode should be supercellular and large hail is expected. Severe wind gusts could materialize along the leading edge of the MCS if it matures as expected. ..Darrow/Thornton.. 06/20/2024 Read more
