Weather Briefing
MVFRPortsmouth International at Pease Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,500 feet and 10 SM visibility.
Wind Analysis
Winds are from the east-southeast (110°) at 9 knots. Runway 16/34 is favored with a 6-knot headwind and 7-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1500 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 13°C (55°F) with a dewpoint of 10°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Showers Rain, Rain, Mist.
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. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.
