  1. @weatherwiz Mesoscale Discussion 1570 NWS Storm Prediction Center Norman OK 1215 PM CDT Wed Jul 10 2024 Areas affected...Parts of central/northern New York Concerning...Tornado Watch 517... Valid 101715Z - 101845Z The severe weather threat for Tornado Watch 517 continues. SUMMARY...Discrete storms in central New York will encounter increasingly favorable environment for tornadoes as the move northeast the next 1-2 hours. DISCUSSION...A few discrete storms have formed north-northeast of Binghamton. With the more dense cloud cover shifting northward, temperatures are beginning to rise into the low to mid 80s F ahead of these storms. Given the favorable storm mode and low-level shear near the warm front (effective SRH around 200 m2/s2 per objective mesoanalysis), the tornado risk with these storms will likely increase over the next 1-2 hours. ..Wendt.. 07/10/2024 ...Please see www.spc.noaa.gov for graphic product...

  3. Mesoscale Discussion 1569 NWS Storm Prediction Center Norman OK 1152 AM CDT Wed Jul 10 2024 Areas affected...South-central Pennsylvania...central Maryland...northern/central Virginia Concerning...Severe potential...Watch likely Valid 101652Z - 101845Z Probability of Watch Issuance...80 percent SUMMARY...Widely scattered to scattered storms will pose a threat of mainly damaging winds and a tornado or two. A severe thunderstorm watch is likely for parts of Virginia into south-central Pennsylvania. DISCUSSION...A very moist airmass is in place across the Mid-Atlantic. Dewpoints are in generally in the low/mid 70s F. Morning observed soundings from the region suggest even limited heating would lead to surface-based destabilization. Current surface observations already show temperatures in the upper 80s to low 90s F which should be sufficient. Visible satellite shows a few updrafts beginning to deepen within the Blue Ridge. Modest mid-level ascent will occur this afternoon, particularly for northern Virginia into south-central Pennsylvania. Coupled with the approach of a cold front from the west, widely scattered to scattered storms are expected. The greatest potential for supercells will be in south-central Pennsylvania into central Maryland/northern Virginia where effective shear will be 35-40 kts. Farther south, multicells will be the predominant mode. Damaging wind gusts will be the primary hazard this afternoon. A low-end tornado threat will also be present for northern Virginia into south-central Pennsylvania, where low-level shear will be slightly greater nearer to the surface low. This is also supported by KCCX/KLWX VAD data. A severe thunderstorm watch is likely for parts of the Mid-Atlantic, though uncertainty is greater with southern extent. ..Wendt/Guyer.. 07/10/2024 ...Please see www.spc.noaa.gov for graphic product...

  4. Updated morning AFD from LWX NEAR TERM /THROUGH TONIGHT/... A stout inversion just off the surface this morning has led to widespread low stratus across Central to Northern VA as warm air advects atop this layer. Increasing southerly winds through the day will eventually mix out these clouds by around noon time. Still on track for hot and very humid conditions this afternoon, with peak heat indices of 100-105 west of the Blue Ridge, and 105-110 to the east. Heat Advisories continue for most of the area, with Excessive Heat Warnings along the I-95 urban corridor from Baltimore to Fredericksburg into Southern MD. The continued evolution of the parameter space this evening continues to favor the development of a line of showers and thunderstorms ahead of a cold front sweeping through the area. Aided by subtle mid-level height falls, lee troughing east of the Blue Ridge, and abundant instability given the high heat/humidity will favor an increasing risk for strong to severe thunderstorms. SPC has upgraded to a Slight Risk (level 2 of 5) across northern VA into northern MD (I-66 north to the MD/PA border). Damaging wind gusts are going to be the primary threat. A tornado or two is also possible, especially in north-central MD where 25-30 kts of 0-1 and 0-3 km shear are present. As for thunderstorm timing, expect convection to begin to bubble over areas just east of Alleghenies (ahead of the dry slot) early to mid-afternoon before advancing toward the I-81 corridor and Blue Ridge around 20-22z/4-6pm. Beyond this point convection continues east toward the metros between 22-2z/6-10pm. Convection gradually wanes before midnight with any severe threat wrapping up after sunset. Convection looks to be fairly progressive with most of the guidance either forming a line or a combination of multicellular clusters. Even with that said, any thunderstorms that due form will be efficient rain producers given PWAT values upwards of 2.2 inches.

  8. Large tornado on the ground west of Evansville in Indiana Severe Weather Statement National Weather Service Paducah KY 430 PM CDT Tue Jul 9 2024 INC051-129-092200- /O.CON.KPAH.TO.W.0117.000000T0000Z-240709T2200Z/ Gibson IN-Posey IN- 430 PM CDT Tue Jul 9 2024 ...A TORNADO WARNING REMAINS IN EFFECT UNTIL 500 PM CDT FOR SOUTHWESTERN GIBSON AND NORTHEASTERN POSEY COUNTIES... At 429 PM CDT, a confirmed large and extremely dangerous tornado was located near Mount Vernon, moving north at 25 mph. This storm has a history of producing a large tornado. This is a PARTICULARLY DANGEROUS SITUATION. TAKE COVER NOW! HAZARD...Damaging tornado. SOURCE...Public confirmed tornado. IMPACT...You are in a life-threatening situation. Flying debris may be deadly to those caught without shelter. Mobile homes will be destroyed. Considerable damage to homes, businesses, and vehicles is likely and complete destruction is possible. The tornado will be near... Poseyville, New Harmony, and Blairsville around 435 PM CDT. Cynthiana around 445 PM CDT. Other locations impacted by this tornadic thunderstorm include Griffin. This includes Interstate 64 in Indiana between Mile Markers 5 and 17.
  9. Sneaky severe threat tomorrow? SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... The remnants of Beryl are expected to pass well to the north across the Great Lakes into New England. However, some of the enhanced synoptic flow may extend southward into the local area. This would be able to interact with the persistent hot, humid, and unstable thermodynamic environment. With that said, the atmosphere is certainly ripe for more widespread showers and thunderstorms. Along or just ahead of a cold front, the latest high-resolution guidance favors a later show than usual with a north/south band of convection pushing eastward to around I-95 by the early/mid evening. This should continue a slow but steady march eastward to the Chesapeake Bay before exiting after midnight. The Storm Prediction Center has upgraded most locations up to a Marginal Risk for severe thunderstorms. The current exceptions would be the Allegheny Mountains and far southern Maryland. Damaging wind gusts are the primary threat, but a brief isolated tornado cannot be ruled, especially for the more northern locations. Vertical shear is a bit stronger coupled with decent cyclonically curved low-level hodographs. Any threat for severe thunderstorms should halt by the overnight hours.
  10. Looks like some random showers and thunderstorms developing across the region. Good luck getting under one

  21. Mesoscale Discussion 1489 NWS Storm Prediction Center Norman OK 1111 AM CDT Sun Jun 30 2024 Areas affected...Portions of central/eastern NC/VA...MD...and DE Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 301611Z - 301815Z Probability of Watch Issuance...80 percent SUMMARY...Thunderstorms are expected to develop over the next couple of hours, posing a risk for damaging wind gusts. A watch will likely be needed for portions of the region withing the next 1-2 hours. DISCUSSION...Portions of northern VA into MD/DE continue to experience greater cloud cover at midday due to earlier day convection. The airmass across this area has been slower to recover as heating has been somewhat slower than surrounding areas. Instability increases with southward extent, and to the east of a surface trough, across southeast VA into northeast NC. With time, much of the region should achieve moderate to strong destabilization given surface dewpoints in the mid 70s F and temperatures climbing into the upper 80s/low 90s F. Vertical shear will be strongest (around 25-30 kt effective shear magnitudes) across northern VA/MD/DE, while decreasing with southward extent into NC. Convection may first develop in the uncapped and moderately unstable airmass near the surface trough across parts of NC into southeast VA. As airmass recovery continues across northern portions of the MCD area, additional storms are expected to develop over the higher terrain of northern VA and shift east through late afternoon/early evening. Thunderstorm clusters will mainly pose a risk of damaging gusts, with potentially some better organized/more intense bowing segments possible further north where better shear overlaps the moderately unstable airmass. Regardless, portions of the MCD area will likely need severe thunderstorm watch issuance within the next 1-2 hours. ..Leitman/Gleason.. 06/30/2024 ...Please see www.spc.noaa.gov for graphic product...
