Heavy rainfall possible in the East next week
A significant storm system is expected to evolve throughout a large majority of the United States over the next several days — with heavy rainfall impacts possible throughout the Eastern US by the middle part of next week. Much of this would come as good news to the drought-ridden areas of the Eastern US, but the uncertainties in regards to the storm systems exact evolution make forecasting the system extremely difficult. Intricate processes at work will determine exactly where and when the heavy rainfall occurs.
The storm system forms initially over the next 48 hours as a strong disturbance evolves into the Plains states. A strong low pressure system at the surface develops rapidly northward into the Dakotas. Precipitation will spread eastwards towards the Corn Belt by early Monday morning as a front boundary surges eastward. But this initial disturbance is not the only feature of interest. While significant aloft, a second disturbance will move through the Rocky Mountain range during the early part of the week, eventually interacting with the initial storm.
