DISCUSSION
Issued at 1224 PM CST Wed Feb 11 2026

Thursday

A shortwave trough will move southeast across South Dakota and Iowa on Thursday. Like the past couple of days, the amount of low and mid-level moisture has continued to decrease. As a result, the rain and snow was removed from the forecast

High temperatures will be in the 30s north of Interstate 94, and in the lower and mid-40s for the remainder of the area.

Weekend

For the upcoming weekend, there will be a split flow across the CONUS. The northern stream is seeing primarily ridging.
Meanwhile, in the southern stream, there will be a shortwave trough moving across the southern US. This system will remain far enough south that the Upper Mississippi River Valley remains on the dry side.

High temperatures will be in the 40s north of Interstate 94, and in the lower and mid-50s for the remainder of the area. Low temperatures on Saturday morning will range from the lower 20s to lower 30s. Meanwhile, low temperatures on Sunday will be in the mid- to upper 20s north of Interstate 94, and in the lower and mid-30s elsewhere.

Monday through Wednesday

On Tuesday and Wednesday, there is a gradual break down of the 500 mb ridge. This will result in the potential for rain. There is a 20 to 30 percent chance south of Interstate 90 and a 30 to 40 percent across the remainder of the area for a tenth of an inch of rain. There is a up to 15 percent chance south of Interstate 90 and a 15 to 30 percent across the remainder of the area for a quarter of an inch of rain.

850 mb temperature anomalies are around 1 standard deviation above normal in the NAEFS, and almost 2 standard deviations in the GEFS. High temperatures will be in the 40s north of Interstate 94, and in the lower and mid-50s for the remainder of the area. Meanwhile, the low temperatures will be in the lower to mid-30s north of Interstate 94 and from the mid-30s to lower 40s elsewhere. These temperatures will be warm enough that some warm low temperature records could be tied or broken. Many of these records were set in 1981.

AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
Issued at 1127 PM CST Wed Feb 11 2026

VFR conditions should largely prevail over the next 24 hours.
However, some valley locations, including LSE, may see visibility reductions overnight, particularly if a break in the mid and upper level clouds occurs. With upper level cloudiness on the increase, current thinking is that this chance is very low (5%). Otherwise, winds should remain under 10 knots and variable but with a more consistent southerly component developing over time.
