This storm has been a roller coaster on the models and Saturday things trended slightly colder than previous runs on Friday. It is now clear that some areas in PA are in store for a major ice storm. Where? Take a look at our updated map and the key in the text below.

AREA A – A short period of snow could break out Mid-Monday Evening, only accumulating to at most an inch. Precipitation type will then switch to sleet for a few hours before Midnight Tuesday and potentially lasting until 2am, followed by an extended period of moderate to heavy freezing rain lasting through the night into Mid-Tuesday Morning. Ice accretion between .2″-.4″ is anticipated, and the melting process will likely last into Wednesday. Traveling will be near impossible Tuesday and scattered power outages are likely.

AREA B – Sleet pellets are likely as the storm moves in Monday Evening before precipitation type quickly changes over to Freezing rain about Mid-Monday Evening. Freezing rain will continue through about just after midnight before temperatures rise above freezing. Ice accretion between .1″-.25″ is anticipated. Some melting will take place but icy conditions will likely stick around into Tuesday until about noon causing rough and potentially hazardous traveling conditions. Isolated power outages are likely.

AREA C – A period of freezing rain is likely Monday Evening before turning to plain rain just before midnight. Ice accretion between .05-.15″ is anticipated, however much of it will melt after temperatures rise above freezing early Tuesday Morning.
