Weather Briefing

VFR

Southwest Wyoming Regional Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 11,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the north (350°) at 12 knots. Runway 03/21 is favored with a 9-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 11000 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 8°C, indicating very dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Thunderstorm Rain. Winds are forecast to reach up to 25 knots during the period. Expect variable wind speeds ranging from 6 to 25 knots. There is a 30% probability of MVFR conditions with Light Thunderstorm Rain between 20:00Z and 00:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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

About Southwest Wyoming Regional Airport

Overview

Southwest Wyoming Regional Airport serves Rock Springs, Wyoming, as a medium-sized regional airport situated at a high elevation of 6,764 feet MSL. The airport provides critical aviation infrastructure for southwest Wyoming, strategically located in a region with significant energy and transportation infrastructure. Its two substantial runways support diverse aviation needs across commercial, cargo, and general aviation sectors.

Flying Conditions

Weather conditions at KRKS predominantly support visual flight rules (VFR), with 90.5% of observations showing VFR conditions. The airport experiences consistent westerly winds averaging 11.9 knots, with occasional strong gusts up to 43 knots. Temperature variations are significant, ranging from -16°C to 27°C, which pilots should anticipate when planning flights, particularly during seasonal transitions.

Notable Features

The airport's high elevation at 6,764 feet MSL requires careful performance calculations for aircraft, especially during warmer temperatures. Both runways are asphalt-surfaced and offer excellent length, with Runway 09/27 providing an extensive 10,000-foot surface. The airport's geographic location in southwest Wyoming presents potential challenges from mountain wave effects and rapid weather changes typical of intermountain western terrain.

Approach Considerations

Both primary runways offer favorable wind alignment, with 100% favorable wind coverage. Runway 03/21 demonstrates an average crosswind of 7.4 knots, while Runway 09/27 shows a slightly more favorable 5.3-knot average crosswind. September, October, and December statistically offer the most consistent VFR conditions, providing optimal flying windows for pilots navigating this high-elevation regional airport.
