KEY MESSAGES
- Seasonably cool and mild temperatures and mostly dry conditions are forecast through the weekend. Next appreciable chance for storms on Tuesday.
..Synopsis
Shortwave ridging dominates over our region between two upper troughs in Canada. This will keep our area under seasonably cool (but mild and comfortable) temperatures this weekend into early next week. There could be some patchy fog during the overnight/early morning periods under clear and calm conditions.
Next appreciable chance for showers and storms comes Tuesday as all ensemble guidance brings a shortwave trough through the southern tier of central Canada into Minnesota. Timing and evolution of the warm sector will dictate how strong or severe storms may be, but at this time, there are no appreciable signals for widespread severe weather.
Getting mid to late next week, upper ridging is forecast to build deeper into the Central CONUS with upper troughing in the Canadian Rockies and Northern Rockies. This will promote temperature trend back toward average to perhaps above average.
It is also worth mentioning that extended range ensemble and AI guidance migrate the aforementioned Rockies' upper trough eastward into the Northern Plains. An attendant upper jet max at the base of this trough is also expected to accompany this trough. With preceding upper ridging helping build instability and heat into the region, it is reasonable to believe that severe potential will increase, perhaps as early as next Saturday.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
Issued at 1042 PM CDT Sat Jun 20 2026
VFR throughout the TAF period. A few cirrus clouds are overspreading the region, but thats it for tonight. Winds will be light as we are under the influence of high pressure to our north. Winds increase a bit out of the east/northeast for Sunday, sustaining themselves up to 10 knots by late morning into the afternoon. Afternoon cumulus will form, but its unlikely to form a ceiling, with bases around 5,000 ft AGL. Winds will decrease again Sunday evening into early Sunday night, as more widespread cirrus starts to overspread the region ahead of our next weather system set to arrive on Monday.
