Updated Sun 27 Sep 14:40 (Europe/Riga)

Wednesday 30 September · AFTERNOON

13:00 - 18:00 · 17 °C · D+3, part of day confidence · models disagree
  • crosswind 1-3 kt, runway 15
  • est. base 1800-2700 ft at 30-60% low cloud
  • visibility 24 km
  • models disagree - treat the timing as provisional
  • D+3: too far out for hour detail, crosswind good to about 6 kt
  • ceiling is a model estimate - no observation exists for EVAD

Sunrise 07:23, sunset 19:01, on the ground by 18:01 (Europe/Riga). The landing deadline is 60 min (the default margin) before sunset. Sun times are computed from the solar position, not taken from the AIP.

Hour by hour

Every value is the median of the three models. Under crosswind, base, low cloud and visibility, a small second line gives each model's own figure (ECMWF · ICON-EU · GFS), so you can see when they disagree. A gust marked (?) came from a model whose gust figure is implausible at that wind speed. At D+3 the hours are not reliable one by one. Read the table for the character of the day.

The base is an estimate

The base is an Espy estimate from model temperature and dew point, read beside low-cloud cover. It is not a measured ceiling. Aim for 2000 ft and make the final call on the day.
