Weather Briefing

VFR

Limon International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 12,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the southeast (140°) at 4 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 12000 feet AGL (broken), well above standard VFR minimums. Caution: towering cumulus clouds reported at 1,500 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 28°C (82°F) with a dewpoint of 25°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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: Rain. Temporary MVFR conditions are forecast with Rain between 10:00Z and 16:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. 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.
