.DISCUSSION...

Issued at 351 AM CDT Sun Mar 22 2026



Current surface analysis places low sliding through the 

Midwest, while high settles through southern

Saskatchewan/Manitoba into the northern plains. Quiet weather 

remains over our area as light precipitation has pushed south of

the area with the approaching surface high.



For today, cooler temperatures are on tap as surface high

settles through central/eastern North Dakota. A short wave

pushing into the area combined with warmer air trying to push in

behind the high may result in some light rain or snow showers

later this morning through this afternoon. 



Milder day on tap for Monday as warmer air continues its push

back in, with high temperatures for many areas running about 10

to 15 degrees above average. A cold front then drops through the

area mid to late day. This will result in a modest cool-down for

Tuesday. 



Tuesday night into Wednesday, warmer air pushes back into the

area while a few weak waves pass through building ridge to the

west. This will result in low to medium precipitation chances,

mainly late night Tuesday. High temperatures on Wednesday will

be quite warm, with highs pushing into the mid 50s to mid 60s

over most locations, about 15 to 20 degrees above average. Cold

front then drops through late Wednesday into Wednesday night,

bringing low precipitation chances through the area. This also

will result in much cooler temperatures for Thursday, with most

locations dropping below average. Gradual warmup then expected

to close out the week.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...

Issued at 1240 PM CDT Sun Mar 22 2026



Lingering low clouds could bring MVFR ceilings through much of

this afternoon to most sites. A few rain or snow showers may

also develop and move from northwest to southeast this

afternoon. Confidence in these showers was only high enough to

include PROB30 mentioning to most sites. Tonight into Monday

morning, VFR ceilings look to return with mainly dry 

conditions. Westerly winds today will become light and variable

this evening, then become southerly tonight into Monday morning.
