Severe Thunderstorm Watch in Effect for Central Indiana A severe thunderstorm watch remains in effect until midnight, covering much of central Indiana. The primary threats include damaging winds and very large hail. Forecasters warn that some thunderstorms could become severe, with isolated tornado risks, particularly near and north of Interstate 70. The Storm Prediction Center has issued Level 1-3 severe risk alerts for Indiana, with the highest risk (Level 3) spanning from Indianapolis to much of north-central Indiana. This area is expected to experience the strongest and most consistent storms. Level 3 zones, marked in orange, indicate scattered to numerous severe storms, while Level 2 (yellow) and Level 1 (green) zones suggest isolated or stray severe storms. However, being in a high-risk zone does not guarantee severe weather, as most areas will see rain and thunderstorms, though not all will face severe conditions. Storm activity is expected to intensify starting around 4-5 p.m., with scattered strong storms possible across northern Indiana, especially between 6 p.m. and midnight. These storms will move west to east, posing the highest risk of hail, damaging winds, and isolated tornadoes. A 20-mile north-south adjustment may occur for the initial wave of storms, leaving the southern half of Indiana relatively unaffected. After 10 p.m., additional waves of rain and storms will develop across northern Indiana, though these will be slightly weaker. These storms will bring widespread gusty winds. Over time, these waves will consolidate into a large band of heavy rain and storms, moving southward and gradually weakening. By Friday morning, severe threats should subside, though leftover rain and thunderstorms may linger through the morning commute, particularly south of Indianapolis.#indianapolis #storm_prediction_center #matt_standridge #central_indiana #interstate_70
Pittsburgh: Severe Weather Alert Day Sunday Afternoon A severe weather alert has been issued for Sunday afternoon in the Pittsburgh area, with scattered strong thunderstorms expected to develop late in the afternoon and continue into the evening. The primary threat from these storms includes damaging wind gusts, heavy downpours, and isolated instances of small to medium hail. Lightening is also a concern with any thunderstorm activity. Temperatures are projected to rise significantly on Sunday, with the day starting in the low 50s and climbing to mid-70s by late afternoon. However, the most active weather will occur after 4 p.m., when showers and thunderstorms are expected to form and move across the region. The earliest storms may arrive north of Interstate 80 around 3:30 to 4 p.m., gradually drifting southward and reaching the Pittsburgh area between 5 and 6 p.m. Areas south of Interstate 70 could see increased chances of severe weather after 6 p.m. The National Weather Service warns that the strongest thunderstorms will peak between 5 and 9 p.m., with the most intense activity likely near and north of I-80. While the severe weather threat is expected to diminish by 9 p.m., scattered showers and thunderstorms may linger until around 2 a.m., with the last remnants of rain clearing by Monday morning. Rainfall totals are anticipated to range from a half inch to an inch across the region, with isolated areas, such as Greensburg, possibly seeing up to an inch of rain. While these amounts are not considered life-threatening, they could lead to localized flooding, particularly in low-lying areas. The weather system will bring a sharp cooldown following the storm, with Monday morning temperatures dropping to the low 40s.#national_weather_service #interstate_80 #pittsburgh #interstate_70 #greensburg
Line of Strong Storms Tonight Followed by Snow on Monday A wind advisory is active across central Indiana from 11 a.m. Sunday to 8 a.m. Monday, with gusts reaching 40 to 50 mph expected. A line of strong to severe thunderstorms is anticipated to move through the region early Tuesday night. Today’s weather will feature mostly cloudy skies, with high temperatures climbing into the lower 70s. Gusty winds will persist during the day, though the period will remain dry before the storm system arrives. Tonight, a squall line will traverse central Indiana from 8 p.m. to 1 a.m. Monday. The National Weather Service has issued an enhanced risk of severe storms for areas along and south of Interstate 70. Damaging winds are the primary threat, with the possibility of embedded spin-up tornadoes within the storm line. Temperatures will drop rapidly behind the storm, with overnight lows expected in the upper 20s. Tomorrow, a lull in precipitation will occur in the early morning, followed by scattered snow showers or snow squalls. On-and-off snow is anticipated throughout the day, with snowfall amounts ranging from a light dusting to 1 inch, and isolated areas potentially receiving up to 2 inches. High temperatures will technically occur at midnight, but daytime peak temperatures will remain in the low to mid-30s. The 7-day forecast indicates another clipper system could bring a rain/snow mix to the start of Wednesday. Temperatures will gradually warm as the week progresses, with a string of days reaching 60 degrees by the end of the week and the start of the following weekend.#national_weather_service #wind_advisory #central_indiana #interstate_70 #squall_line
