SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Fri Jul 21 2023 Valid 221200Z - 231200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL PLAINS INTO THE UPPER MIDWEST...SOUTHEAST...AND ARIZONA... ...SUMMARY... Widely scattered strong to severe thunderstorms appear possible on Saturday across parts of the central Plains into the Upper Midwest, Southeast, and Arizona. ...Synopsis... An upper ridge will remain centered over much of the western CONUS Saturday, while broad upper troughing encompasses the central and eastern states. Modestly enhanced west-northwesterly mid-level flow should be present between these two features. Greater low-level moisture should remain confined to parts of the Southeast along and south of a convectively reinforced front. But, sufficient moisture across the central Plains and Upper Midwest should be in place to support at least isolated robust convection. ...Central Plains/Upper Midwest... Around 30-40 kt of northwesterly mid-level flow will remain over much of the central Plains into the Upper Midwest on Saturday. While low-level moisture may remain fairly shallow/limited by late July standards, steepened low/mid-level lapse rates and daytime heating should promote the development of weak to moderate instability by late Saturday afternoon. Large-scale ascent appears nebulous, but isolated to scattered convection may still develop along and southeast of a weak surface trough. With 25-40 kt of deep-layer shear forecast, a widely spaced mix of multicells and supercells may develop and spread southeastward through Saturday evening while posing an isolated threat for large hail and severe wind gusts. Based on latest guidance, have expanded the Marginal Risk to encompass more of the central Plains and Upper Midwest. ...Southeast... Scattered showers and thunderstorms may be ongoing Saturday morning across parts of MS/AL into GA and perhaps SC. The convectively reinforced outflow/front and a separate sea breeze will likely be foci for renewed convective development by Saturday afternoon. A belt of modest westerly mid-level winds at the base of the large-scale upper trough will exist across much of the Southeast. Plentiful low-level moisture, with surface dewpoints generally in the 70s, and ample diurnal heating will likely foster moderate to strong instability by early Saturday afternoon. Scattered to numerous thunderstorms should develop in this environment along and south of the front. Strong to locally damaging winds may occur with the more robust convection given the very moist profiles, and some clustering may occur. Isolated hail also appears possible with the strongest cores. At this point, not enough confidence exists to include greater severe wind probabilities. But, have expanded the Marginal Risk to include more of the Gulf Coast into north FL. ...Arizona... An upper-level anticyclone will remain centered near the Four Corners region Saturday. It appears that modest (15-20 kt) east-northeasterly mid-level winds will be present across parts of southern AZ and vicinity. As thunderstorms develop over the higher terrain, there may be enough low/mid-level flow to push this convection westward into the lower terrain of southern/central AZ. Very steep low/mid-level lapse rates with a well-mixed boundary layer and ample DCAPE should support some threat for severe winds if this occurs. With a better signal of this potential in recent high-resolution guidance, have added a Marginal Risk for severe/damaging winds. ..Gleason.. 07/21/2023 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1134 AM CDT Fri Jul 21 2023 Valid 211700Z - 221200Z ...17z Update... Across parts of the Northwest, morning surface obs showed a few areas of gusty winds through the Cascade Gaps and western Columbia Basin. Fair to moderate overnight humidity recoveries will quickly erode this morning, with afternoon RH values below 25% likely. Gusty west winds through the gaps are expected through the afternoon hours with brief, locally elevated, fire-weather conditions possible. The Elevated area over the Columbia Gorge was modified slightly for the latest guidance. Please see the prior discussion for more information. ..Lyons.. 07/21/2023 .PREV DISCUSSION... /ISSUED 1251 AM CDT Fri Jul 21 2023/ ...Synopsis... An upper-level ridge will remain across the West today, roughly centered within the Great Basin into the northern Rockies. In the Northwest, an upper-level trough will approach the area through the period. The strongest winds will reach western portions of the region around Saturday morning. At the surface, the pressure pattern for most areas west of the Divide will be diffuse. A thermal pressure trough will develop in the Columbia Basin. Fire weather concerns will generally be low across most areas with dry fuels given weak surface winds. Hot and dry conditions are likely within much of the Great Basin and Southwest. Where winds are locally stronger, localized elevated conditions may occur. ...Columbia Gorge... A few hours of marginally elevated fire weather conditions are possible during the afternoon. Confidence in RH reaching 15-20% is reasonably high, though some guidance shows only 20-25%. Winds will be the limiting factor. Only around 15 mph winds are expected with perhaps brief periods near 20 mph within the terrain itself. The potential for stronger winds will be limited as the surface trough will be modest and stronger mid-level flow will not arrive until after the diurnal RH minimum. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1116 AM CDT Fri Jul 21 2023 Valid 211630Z - 221200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MID-SOUTH/TENNESSEE VALLEY/SOUTHEAST...NORTHEAST STATES...AND SOUTHERN HIGH PLAINS... ...SUMMARY... Severe thunderstorms capable of wind damage and some hail are expected across the Mid-South and Tennessee Valley to the Southeast States, while additional severe storms will be possible across the Northeast and High Plains. ...AR into the Southeast States... A large MCS that tracked across southern OK last night is now over northern/central AR. This system and its attendant MCV will move into western TN this afternoon, where sufficient heating and a very moist air mass will support the potential for re-intensification. If this scenario occurs, locally damaging wind gusts would be the main concern. To the southeast of the MCS, a weak surface boundary extends across southeast AR into portions of MS/AL/GA. A very unstable air mass will become established this afternoon along this axis, where scattered thunderstorm development is expected. MLCAPE values around 3000 J/kg will combine with winds in the 5-7km layer around 30 knots to pose some risk of damaging wind gusts in the stronger cells. The risk of wind damage will increase later this afternoon if sufficient thunderstorm coverage can result in more organized outflows. ...New England... An upper trough is moving across the northeast states today, with an associated cold front currently extending across parts of eastern NY/PA. Clouds have been clearing ahead of the front across western New England, where temperatures will rapidly warm into the 80s. Ample low-level moisture is present from southern VT/NH southward, where upper 60s/lower 70s dewpoints will yield afternoon MLCAPE values of 1500-2000 J/kg. Forecast soundings show sufficient deep layer shear for a few organized/rotating storms capable of strong/damaging wind gusts and perhaps hail for a few hours this afternoon. ...Northeast NM... Weak easterly low-level upslope flow is present today over northeast NM, helping to transport 60s dewpoints westward toward the higher terrain. Thunderstorms are expected to form in the mountains near Raton and drift southeastward through the afternoon. Steep low-level lapse rates and 30-40 knots of effective shear will promote the development of a few supercells capable of large hail and damaging wind gusts. ..Hart/Thornton.. 07/21/2023 Read more

MD 1653 CONCERNING SEVERE THUNDERSTORM WATCH 526... FOR SOUTHEAST WYOMING INTO EASTERN COLORADO
Mesoscale Discussion 1653 NWS Storm Prediction Center Norman OK 0519 PM CDT Thu Jul 20 2023 Areas affected...Southeast Wyoming into Eastern Colorado Concerning...Severe Thunderstorm Watch 526... Valid 202219Z - 210015Z The severe weather threat for Severe Thunderstorm Watch 526 continues. SUMMARY...All severe hazards will remain possible this afternoon into the evening, particularly for southeast Colorado. The tornado threat will be maximized along/near a surface boundary from near Lamar to northeast of Pueblo. DISCUSSION...Numerous supercells continue in eastern Colorado into southeast Wyoming. The most intense of these storms are in southeast Colorado where surface heating has been greater. Strong northwesterly effective shear and MLCAPE of 1500-2000 J/kg (maximized in southeast Colorado with lesser amounts farther north) will continue to support supercells capable of severe wind gusts, large to very large hail, and perhaps a tornado or two. A surface boundary is evident within surface observations and local radar imagery in southeast Colorado. KPUX VAD profiles show slightly more enlarged low-level hodographs as a result. The tornado threat this afternoon will be maximized along/near this boundary. With time, storm interactions should lead to upscale growth into an MCS, a consensus scenario in high-resolution guidance. At that time, severe wind gusts (some exceeding 75 mph) would become the primary threat. For northeast Colorado into southeast Wyoming, the overall threat will be somewhat mitigated by lesser buoyancy and more stable air just to the east. ..Wendt.. 07/20/2023 ...Please see www.spc.noaa.gov for graphic product...

A new watch appears likely. DISCUSSION...A line of storms extending across northern GA and into far northeast AL is producing measured severe gusts over 50 kt at multiple observing sites. Westerly low-level winds will continue to feed unstable air into the region ahead of this line of storms as it moves southeastward this evening. Although effective shear is only on the order of 25-30 kt, similar deep-layer mean wind speeds will favor a forward-propagating system with strong to severe outflow. Given the uncapped air mass downstream with mid 70s F dewpoints and MLCAPE around 2500 J/kg, the threat may extend to the coast. As such, a continued severe risk is anticipated given ample instability and current organization of this system. ..Jewell.. 07/20/2023 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1651 NWS Storm Prediction Center Norman OK 0449 PM CDT Thu Jul 20 2023 Areas affected...Southwest Kansas...Oklahoma Panhandle...northern Texas Panhandle...northwest Oklahoma Concerning...Severe Thunderstorm Watch 527... Valid 202149Z - 202345Z The severe weather threat for Severe Thunderstorm Watch 527 continues. SUMMARY...All severe hazards will be possible late this afternoon and evening. Very large hail threat will focus in southwest Kansas near Dodge City. Tornado threat will focus along a surface boundary in the combined Panhandles. The primary hazard will eventually be severe (potentially significant) wind gusts as an MCS organizes and moves out of southeast Colorado. DISCUSSION...An ongoing, intense supercell continues across parts of southwest Kansas just north of Garden City. Hail of 1.75-2.5 inches has already been reported with this storm and current dual-pol radar presentation from KDDC would suggest very large hail remains a potential threat. Furthermore, a tornado has been reported with this storm as well. This storms and any other that develop nearby are the greatest short-term severe threat. Later this evening, convection that is ongoing in eastern Colorado is expected to grow upscale. Temperatures near 90F and dewpoints in the upper 60s to low 70s F will support moderate to strong buoyancy late this afternoon and evening. Combined with strong northwesterly effective shear, this environment will support potential for an intense line of storms capable of scattered severe wind gusts (some of which may exceed 75 mph). Given the linear storm mode expected, the tornado threat will be somewhat modulated. The greatest threat for a tornado or two would be along and just north of the surface boundary into the Texas/Oklahoma Panhandles. ..Wendt.. 07/20/2023 ...Please see www.spc.noaa.gov for graphic product...
