Forecast Periods
📖 Plain English Explanation:
This is the base forecast condition. Winds from the East-Southeast (120°) at 8kt. Visibility will be good at 3SM. Weather conditions: Light Snow. Overcast skies at 500 feet. Instrument Flight Rules (IFR) conditions - instrument flying required.
📖 Plain English Explanation:
Temporary conditions (lasting less than an hour at a time) may include: Visibility will be excellent at more than 6SM. Weather conditions: Light Snow. Scattered clouds at 500 feet, Overcast skies at 1200 feet. Instrument Flight Rules (IFR) conditions - instrument flying required.
📖 Plain English Explanation:
There is a 30% probability of: Visibility will be moderate at 1/2SM. Weather conditions: Light Snow, Mist. Instrument Flight Rules (IFR) conditions - instrument flying required.
📖 Plain English Explanation:
Winds from the South-Southwest (210°) at 12kt. Gusts up to 22kt are expected. Visibility will be moderate at 1/2SM. Weather conditions: Light Snow. Broken clouds at 1200 feet, Overcast skies at 2500 feet. Instrument Flight Rules (IFR) conditions - instrument flying required.
📖 Plain English Explanation:
Temporary conditions (lasting less than an hour at a time) may include: Visibility will be excellent at more than 6SM. Weather conditions: Light Snow. Scattered clouds at 1200 feet, Overcast skies at 2500 feet. Marginal VFR conditions - some restrictions for visual flying.
📖 Plain English Explanation:
There is a 30% probability of: Visibility will be moderate at 1/2SM. Weather conditions: Light Snow, FCST. Vertical visibility at 1000 feet. Instrument Flight Rules (IFR) conditions - instrument flying required.
📚 Understanding TAF Forecasts
Terminal Aerodrome Forecast (TAF) provides detailed weather forecasts specifically for aviation operations. Our system translates complex meteorological codes into plain English to help pilots of all experience levels understand forecasted conditions.
What TAF Includes:
- • Wind direction, speed, and gusts
- • Visibility in statute miles or kilometers
- • Weather phenomena (rain, snow, fog, thunderstorms)
- • Cloud coverage types and altitudes
- • Forecast changes with timing
- • Flight rules categories (VFR/IFR)
Change Indicators Explained:
- • BASE - Main forecast conditions
- • FM - Permanent change from specific time
- • BECMG - Gradual change over 2-4 hours
- • TEMPO - Temporary changes (less than 1 hour)
- • PROB30/40 - 30% or 40% probability
🛩️ Flight Rules Categories
VFR
Visual Flight Rules
- • Ceiling ≥ 3000 ft
- • Visibility ≥ 5 miles
- • Good for visual flying
MVFR
Marginal VFR
- • Ceiling 1000-3000 ft
- • Visibility 3-5 miles
- • Caution for VFR
IFR
Instrument Flight Rules
- • Ceiling 500-1000 ft
- • Visibility 1-3 miles
- • Instruments required
LIFR
Low IFR
- • Ceiling < 500 ft
- • Visibility < 1 mile
- • Challenging conditions
💡 TAF Reading Tips
For Student Pilots:
- • Focus on the plain English explanations above
- • Pay attention to flight rules categories
- • Look for wind direction relative to runway headings
- • Check for temporary conditions (TEMPO)
For Experienced Pilots:
- • Cross-reference with raw TAF for precise timing
- • Consider probability forecasts for alternate planning
- • Monitor BECMG periods for gradual changes
- • Always check current METAR vs TAF forecast
Important: TAF forecasts should always be supplemented with current METAR observations, PIREPs, and other weather information for complete situational awareness. Weather can change rapidly, and forecasts have inherent limitations.
