Synopsis


Some stratiform RAIN will linger this afternoon and evening before moving east. NO SIG is expected overnight and Tuesday morning.

Currently, the axis of a trough is situated in west-central Montana. To the north, an upper level low in northern Manitoba will move east as the trough moves east. Flow within this trough will continue to strengthen, and western North Dakota will likely be in the entrance region of a jet streak this evening. The best flow will continue to move south and east though, likely exiting D1 by 12z as zonal flow takes shape. Below, backing winds from the surface to 700mb will limit deep convection today, especially given the lack of instability and adequate moisture. Northerly to northwesterly winds driven by surface high pressure to the west will persist throughout the forecast period as temperatures struggle to reach past 55F today.

Currently, precipitation is falling across much of western North Dakota as stratiform rain. Some stratiform RAIN will linger this afternoon and possibly as late as 3z this evening. Most models tend to agree with this time, though a couple maintain rain for longer. Nonetheless, any precip that falls through tomorrow's briefing will be unseedable. NO SIG will take over after 3z as the rain moves out.
