Oct 15: Rain and Wind Approaching!

A strong upper level low continues to push a frontal passage eastward into slowly departing high pressure causing southerly flow, rain and wind. The main area of precipitation is currently over western Maryland and central PA. This will slowly filter eastward into New Jersey today as early as this afternoon but definitely by nightfall. The heaviest periods of rain and wind will occur overnight but should clear by rush hour from SW to NW. Although there might be some lightning, Severe Thunderstorm Warnings will likely be triggered for wind (if triggered). This is the 12Z high-res 4km NAM showing expected precipitation intensity at 1AM tomorrow morning:

Expect temperatures to drop after this frontal passage. A few inches of rain are possible as well as isolated instances of 40-60mph wind gusts. The NWS SPC has a small chance of isolated tornadoes as well so please be safe! JC
