** SEVERE WEATHER THREAT THIS AFTERNOON / EVENING (SUNDAY 6/14) **
We have a rather unique setup coming this afternoon and evening as a cold front with stronger wind shear and rising temps/humidity will lead to growing instability throughout the afternoon hours, spelling the risk for strong to severe thunderstorms.
Looking over the model guidance, there will be the risk for a squall line to move through western/central Pennsylvania, while there may be the risk for multi/supercells forming off of a convergence boundary in central Pennsylvania, moving into portions of south-central and southeastern Pennsylvania. If a mesolow develops in northwestern PA, this could increase the tornado risk even farther in northwestern PA within the squall line.
BEST TIMING: A 'best' timing graphic will be followed shortly after this post for a lot of the towns/cities in Pennsylvania.
⚠️Like any other severe weather day, take all alerts very seriously. If a tornado/severe watch is issued, this means you should be prepared as the atmosphere is conducive to stronger thunderstorms. If a tornado/severe warning is issued, this means severe weather is imminent, and it is urgent that you take shelter in a sturdy building. ⚠️
(ZONE 2, RED): Scattered strong to severe thunderstorms are expected. The strongest storms may pack wind gusts of 60 - 65 mph with hail up to penny-sized. Brief tornadoes may be expected within the line of storms (primarily western PA). Non-severe impacts may include torrential downpours and lightning.
(ZONE 1, YELLOW): Isolated strong to severe thunderstorms are expected. The strongest storms may pack wind gusts of 55 - 65 mph. A brief tornado is possible in the strongest, rotating storm. Non-severe impacts may include torrential downpours and lightning.
-> Keep in mind, severe weather does not impact every house or neighborhood. Unless it is a large outbreak, severe weather impacts will differ even across small areas. It is always good to be prepared by having multiple ways of receiving severe weather alerts and a shelter to take cover in when severe weather strikes.
