Scattered showers with embedded heavy downpours have impacted a large majority of the area this morning, and will continue to do so during the early afternoon hours. Forecast models and regional observations are aligned in the idea that an area of steadier, heavier rain will begin to approach the region this afternoon. The rain may be torrential at times, with rapid rainfall amounts leading to localized flooding.
This rainfall will be occurring as a result of a strengthening low level jet, or the movement of air in the lower levels of the atmosphere. The strong low level jet is associated with a strong system aloft, passing along the East Coast today. The low level jet will transport moisture into the region rapidly, and enhance lift to help develop precipitation from southeast to northwest during the early to mid afternoon.
