Forecast Discussion

A coastal low will continue to slowly make its way north along the eastern seaboard today into Friday. Several bands of precipitation will rotate in, with the heaviest bands moving in today. Steady rain will eventually give way to more showery type precipitation overnight into Friday. Temperatures will be warming enough today to allow for all rain; but as the low lifts north, colder air will filter in. This will allow for a transition to freezing or frozen precipitation after midnight tonight and continuing into Friday. A band of thunderstorms is rotating northwest this morning and models are indicating a continued chance through Thursday. Heavy rain may also bring a risk of flash flooding in neighboring ravines today w/ swollen water crossings expected today through tomorrow. Additionally, for elevations above 5000 feet, precipitation fell as freezing rain for a significant part of Wednesday before transitioning to rain. This has left a coating of water-logged ice on all surfaces making for extremely slippery surfaces. I strongly recommend bringing additional ice cleats or traction devices like Yaktrax, MICROspikes or an equivalent for any travel above 5000 feet.
