DISCUSSION

Issued at 330 AM CDT Fri Apr 10 2026

Surface high will bring light winds to start today. Northwest flow aloft bringing some mid level clouds as well this morning. Areas with light winds and clear skies could see some patchy fog this morning, mainly in southern and northern portions. As the surface high moves eastward, breezy southerly winds will begin to develop in westerly portions. This will bring warming temperatures today with highs in the 50s to lower 60s across the west and 40s east. Lowering RH values this afternoon combined with these increasing winds may bring some elevated fire weather concerns, although winds and RH should fall short of critical fire weather conditions. Increased pressure gradient at the surface will continue breezy southerly winds through tonight, with mild lows in the 30s. Surface low then forms lee of the northern Rockies Saturday. This will continue breezy southerly winds across most of central and eastern North Dakota while bringing warm temperatures in the 70s west to 50s east. Increasing moisture in southerly flow, combined with an 850 mb shortwave could also provide for some rain showers, drizzle, and perhaps elevated thunderstorms across the east on Saturday. CSU-MLP still showing some low probs for severe weather in the east on Saturday, although perhaps more far eastern ND is impacted by this. More showers and thunderstorms could then develop Saturday night as the surface low moves through. Low probability for stronger thunderstorms may also be found at this time, however these should remain elevated if any thunderstorms can develop. Lows Saturday night will be mild and generally in the 40s. Sunday still looks to be warm with highs in the 60s to lower 70s, and unsettled with the surface low continuing to move through. Showers and thunderstorms remain possible, although CSU-MLP has shifted chances of severe weather eastward. A breezy westerly flow may develop after the surface low moves through on Sunday. Surface cold front is then forecast to move across the state from north to south Sunday night, bringing more rain chances and some elevated thunderstorms. Lows could cool somewhat to the 30s north to the 40s south.

Weakly organized trough pattern could then be found for next week. A split flow pattern could begin Monday, along with the remnants of the mentioned cold front. Showers could linger through Monday and into Monday night as a result along with slightly cooler temperatures. Weak instability could again bring some chances for thunderstorms Monday, while cooler temperatures in the north could bring some rain and snow chances Monday night. Tuesday or Wednesday could see a break in the weather before the next trough pattern moves into the area. Look for diminished precipitation chances these days along with mild temperatures. Clusters then indicate the next trough pattern could return towards the end of next week. Rain and snow chances could return as a result along with the potential for cooling temperatures although NBM spreads remain large and will depend on timing of this next trough feature.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Mainly clear to partly cloudy skies and VFR conditions will be found during the forecast period. Light winds this morning will become a breezy southerly wind today and continue through tonight. Some low level wind shear could return tonight, although confidence was not high enough to include in the TAFs at this time.
