** SEVERE WEATHER OUTBREAK EXPECTED MONDAY AFTERNOON / EVENING **
A very dynamic system will be moving into the region tomorrow, which will bring numerous severe thunderstorms to much of central and portions of eastern Pennsylvania on Monday afternoon and evening. A strong cold front will cross the state, spawning a powerful squall line. Within the squall line, there may be circulations that could support weak spin-up tornadoes. Ahead of the squall line, any individual cells that develop can become supercells and can also produce weak tornadoes and damaging wind gusts. Tomorrow is one of the higher-end days that we've seen as of late, so it is important you stay tuned for updates and remain weather alert.
ZONE 3 (A)- Watching for *NUMEROUS* strong to severe thunderstorms. These storms may produce damaging wind gusts of 70 to 80 MPH. A few spin-up weak tornadoes are not ruled out, and if one were to occur, it would likely be low intensity (EF0-EF1). An isolated supercell could produce up to EF2 strength. Non-severe thunderstorms may still produce gusty winds, lightning, and heavy rainfall.
ZONE 2 (B)- Watching for *SCATTERED* strong to severe thunderstorms. These storms may produce damaging wind gusts of 55 to 70 MPH. A few spin-up weak tornadoes are not ruled out, and if one were to occur, it would likely be low intensity (EF0-EF1). Non-severe thunderstorms may still produce gusty winds, lightning, and heavy rainfall.
ZONE 1 (C)- Watching for *ISOLATED* strong to severe thunderstorms. These storms may produce strong wind gusts of 50 to 60 MPH. Non-severe thunderstorms may still produce gusty winds, lightning, and heavy rainfall.
Monday will be a good day to remain weather aware and stay tuned for updates. Be prepared for rapidly changing weather conditions. Make sure you have multiple ways to receive severe weather alerts. Remember, when you hear thunder, head indoors! Stay safe and stay tuned! ⚠️🌪️
