24 Hour Aviation Hazards Summary

Prior to every flight, pilots should gather all information vital to the nature of the flight. This site is informational in nature and is designed to assist pilots and aircrews for flight planning and weather familiarization. It may be used in conjunction with other preflight information sources needed to satisfy all the requirements of 14 CFR 91.103 and is not to be considered as a sole source of information to meet all preflight action. Pilots can complete their regulatory-compliant preflight briefing by using other automated resources or from Flight Service at www.1800wxbrief.com or by calling 1-800-WX-BRIEF.

Lowest Expected Flight Conditions

The lowest expected flight conditions indicated below are derived from hourly ceiling height and visibility forecasts, which are updated around 00 UTC, 06 UTC, 12 UTC and 18 UTC.

Local Area Aviation Weather Discussion

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
VFR conditions will largely prevail through the period for most
terminals. The main exception will be isolated thunderstorms 
developing over the higher terrain near EKN this afternoon and 
early evening. Given the sparse coverage and the disorganized 
nature of the convection, confidence in direct terminal impacts 
is too low to include anything beyond VCTS at this time. 
However, any direct impact could produce brief MVFR/IFR 
visibility reductions and gusty, erratic winds. 

Patchy fog may develop at EKN overnight as winds decouple, more
likely if any precipitation falls at the terminal this 
afternoon.

Southwest surface winds of 8 to 10KTs, with occasional gusts to
20KTs will persist through the afternoon before decoupling 
around sunset.
