Stalled boundary brings daily shower and thunderstorm chances this week

TODAY: Humid with clouds, breaks of sun, and showers or a t-storm. High: 81

TUESDAY: Humid with clouds, some sunshine, and a shower or t-storm. High: 81 Low: 65

FLASH FLOOD WATCH FOR MUCH OF EASTERN PENNSYLVANIA, NEW JERSEY, AND NORTHERN DELAWARE FROM 12 P.M. MONDAY THROUGH EARLY TUESDAY MORNING.

A front that arrived on Father's Day will be the gift that keeps on giving all week long. It stalls out across the area with ripples of low pressure riding along it, bringing daily shower and thunderstorm chances until a stronger frontal boundary kicks it out to sea Friday. Repeated rainfall over the same spots may lead to flooding with much of eastern Pennsylvania, New Jersey, and northern Delaware collecting between 1-3" with locally higher amounts where stronger thunderstorms develop.

Neither day will be a washout, including today when the wettest time-frame will be during the afternoon and evening. That's when some strong to possibly severe thunderstorms may develop. The Storm Prediction Center places the greatest odds for damaging wind gusts and large hail in the Delaware Valley and southern New Jersey. That's where there's a "slight risk," or level 2 out of 5. The threat for severe weather diminishes the farther north one travels.

It's rinse and repeat through Thursday and Friday when a stronger system will be sliding through the state, eventually kicking our stalled front out to sea and ending our stormy weather spell for the upcoming weekend. Rain and thunderstorms may be more numerous later Thursday and early Friday before drying out Friday night. The first weekend of summer Saturday and Sunday is trending dry, partly sunny, and seasonably warm with highs in the lower 80s.
