.DISCUSSION...
Issued at 151 AM CST Fri Feb 27 2026

Critical fire weather conditions are expected today across the
entire forecast area. Temperatures will soar into the 70s this
afternoon with deep mixing leading to extremely dry conditions.
Afternoon humidity values may fall as low as 15%. While winds won`t
be extreme, wide spread wind gusts of 20-30 mph are expected. Given
the hot, dry, and windy setup, have upgraded the Fire Weather Watch
north of the Missouri River to a Red Flag Warning. Additional,
expanded the Red Flag Warning south of the Missouri River to include
the entire forecast area.

Impactful wintry weather continues to be a major concern for Sunday
into Monday. The Thursday afternoon/evening suite of guidance
suggests a bit a northward trend in the mixed precipitation
area. This trend has shifted the higher probabilities of at
least 1" of snow for the 24 hours ending Monday morning to be
mainly north of the Missouri River. Additionally, with northward
push, the greatest potential for freezing has shifted north as
well. With the latest suite of ensemble guidance, there is about
a 30-55% chance for at least an inch of snow north of the
river. For freezing rain there is about a 20-40% chance for at
least 0.01" north of the river. Though there remains a narrow
corridor of similar probabilities along the Highway 50 corridor.
This remains a highly variable forecast, as could be expected,
with critical temperatures hovering/waffling across the forecast
area. Forecast trends will need to be monitored as the critical
rain/snow line continues to vary. As mentioned in the previous
discussion, while confidence remains low on precipitation type
and timing, confidence in impactful wintry weather is fairly
high.

Beyond this wintry system, the weather pattern looks very unsettled
next week with multiple chances for rain and even potential for
thunderstorms. Naturally, there remains considerable uncertainty in
timing of the various systems leading to this rainfall. But there is
a strong signal that temperatures will be warm enough for all liquid
precipitation. And totals through the end of next week could be
significant with a 35-55% chance for at least 2" of rain for the 72
hour period ending Saturday morning and a 10-20% chance for at least
3" of rain for the same time frame.
