KEY MESSAGES

- Low (<30%), light snow chances north of Interstate 90 on Thursday morning with <1" expected.

- Increased chances (40-60%) for snowfall on Saturday. Narrow band of heavier snowfall will be possible.

- Warm temperatures for Friday appear short-lived as daytime highs sink into the 20s through the weekend. Near seasonable temperatures appear to return for early next week.

DISCUSSION

Issued at 1029 PM CST Tue Feb 24 2026

Snowfall Chances Thursday & Saturday:

Embedded shortwave pulses along upper level northwest flow suggest light snow chances for some of the forecast area initially Thursday morning. Overall accumulations expected remain light, primarily north of Interstate 90. Current timing may affect the morning commute. A subsequent, potentially heavier narrow band of snow possible on Saturday with a strong quasi-zonal signal for enhanced frontogenesis through the Upper Midwest. While the GEFS (25.12Z) doesn't tie on to this solution, both the GEPS (25.12Z) and EPS (25.15Z) show snowfall probabilities decreasing towards the forecast area, suggestive of the weakening wave while progressing southeast. Regardless, will be subsequent accumulations to remain cognizant of. Most recent EPS (25.18Z) shows a mean 1" of snowfall at KLSE through the early weekend, assuming a 10:1 SLR.

Warm Friday, Cooler Weekend:

A rapid warm up for the end of the work week appears short lived as daytime highs drop back into the 20s for the weekend. The sharp north-south low level temperature gradient strewn across the forecast area through the weekend leaves some questions with exact location of warmer/colder air to the south/north. Regardless, currently low (30-50%) confidence for near seasonable temperatures returning into early next week.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 535 AM CST Wed Feb 25 2026

A decaying MVFR stratocumulus deck continues to dissipate through the morning with VFR conditions expected for much of the day and into the night. There is some signal for lower stratus and/or fog towards sunrise tomorrow, but confidence in this solution is low (10%) at the present time. Northwest winds of 10-15G20kts slowly decrease today and become light and variable after 00Z before turning to the south after 06Z at 5-10kts.
