Weather Briefing

MVFR

Karl Stefan Memorial Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 8,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the west-northwest (290°) at 5 knots. Runway 32 is favored with a 4-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 2700 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 6°C (43°F) with a dewpoint of 4°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Karl Stefan Memorial Airport

Overview

Karl Stefan Memorial Airport serves Norfolk, Nebraska, functioning as a medium-sized airport located in the north-central part of the state. Situated at 1,573 feet above mean sea level, the airport provides critical aviation infrastructure for the surrounding region, with two parallel asphalt runways each measuring 5,800 feet in length.

Flying Conditions

Weather conditions at KOFK demonstrate predominantly favorable flying environments, with 73.5% of observations reporting Visual Flight Rules (VFR) conditions. The airport experiences significant seasonal temperature variations, ranging from -23°C to 33°C, with September, October, and January offering the most consistent VFR conditions. Winds predominantly originate from the south at an average speed of 9.9 knots, with occasional gusts up to 35 knots.

Notable Features

Both runways (01/19 and 14/32) offer excellent wind alignment, with 100% favorable wind coverage. The airport's geographic positioning and runway configuration provide flexibility for pilots during various wind conditions, with average crosswinds of 5.9 knots on runway 01/19 and 4.2 knots on runway 14/32. Visibility averages 9.3 statute miles, with minimal instances of restricted visibility.

Approach Considerations

Pilots can expect reliable approach conditions, with only 6.2% of observations reporting Instrument Flight Rules (IFR) and a low 4.3% reporting Low IFR conditions. The consistent southerly winds suggest runway 01/19 and 14/32 will typically provide straightforward approach and landing scenarios. Calm wind conditions occur approximately 9.5% of the time, further enhancing operational predictability.
