Synopsis


Most of today should be clear, with brief chances for weather in each district. An upper level trough is moving into the region through the next few days. A surface low pressure system is expected to move into Western North Dakota overnight, possibly influencing the weather. District 1 is expected to be warm and dry most of the forecast period, however a pocket of moisture is expected to pass through overnight as the surface low and stationary front pass. This could allow for precipitation, however convective development is unlikely. District 2 is expected to have higher dewpoints than District 1 and a region of CAPE is expected to develop in Mountrail County overnight. A shortwave trough is expected to move through the region in the late evening. Thunderstorms are possible in District 2, especially if the forcing and CAPE occur at the same time.
