Weather Briefing

MVFR

Northeast Wyoming Regional Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,700 feet and 10 SM visibility.

Wind Analysis

Winds are from the northwest (310°) at 20 knots with gusts to 29 knots. Runway 34 is favored with a 17-knot headwind and 10-knot crosswind component (gusting to 15 knots crosswind). Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 2300 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 4°C (39°F) with a dewpoint of 2°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 21 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Showers RASN. Winds are forecast to reach up to 20 knots during the 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 Northeast Wyoming Regional Airport

Overview

Northeast Wyoming Regional Airport serves Gillette, Wyoming, situated at an elevation of 4,365 feet MSL in the northeastern part of the state. The airport provides critical transportation infrastructure for the region, featuring two concrete runways that support medium-sized airport operations. Its strategic location supports both commercial and general aviation needs in this part of Wyoming.

Flying Conditions

Flight conditions at KGCC are predominantly VFR, with 84.3% of observations showing visual flight rules conditions. Temperature variability is significant, ranging from -24°C to 32°C, which can present challenging seasonal transitions for pilots. The prevailing southerly winds at an average of 10.9 knots, with occasional gusts up to 40 knots, create consistent wind conditions that pilots must consider during flight planning.

Notable Features

The airport's dual runway configuration (03/21 at 5,803ft and 16/34 at 7,500ft) provides operational flexibility for different aircraft types and wind conditions. Both runways demonstrate 100% favorable wind alignment, with modest average crosswind components of 6.8 and 6 knots respectively. The high elevation of 4,365 feet MSL will impact aircraft performance, particularly during warmer months.

Approach Considerations

Visibility averages 9.6 statute miles, with only 1.8% of observations showing visibility below 3 miles. Pilots should note that September, October, and January offer the most consistent VFR conditions. The southerly prevailing winds suggest runway 16/34 may frequently be the preferred approach, though pilots should always confirm current ATIS and wind information before landing.
