General Update ...
Work is proceeding very well on the new Beta Version 2.50.0 which includes the following additions and enhancements.
The
Local Weather Report window will now distinguish between Light and the
new Very Light rain/snow intensities. Reported drizzle, small hail/snow
pellets, snow grains, and ice pellets will now result in Very Light
precipitation. Similar conditions will be assumed with reported light
rain/snow when there is little cloud cover.
There
are now options to specify the destination and two alternate airfield
designations within the Weather dialog. New destination, 1st Alternate,
and 2nd Alternate Weather Report windows have been added to provide
accurate weather reports for the user's specified destination and two
alternate airfields. These reports can be used in place of ATIS and are
accurate out to the edge of the weather map (over 300 miles out). The
ICAO codes and where appropriate the station names are now listed within
each of the four weather report windows.
The
pressure stabilisation improved between successive weather updates in an
attempt to prevent problems flying the PMDG MD-11 and similar aircraft.
Some new recovery conditions have been added and the weather smoothing
has been relaxed for the areas surrounding the specified destination and
alternate airfields.
The OpusWeather.txt file is no longer updated during METAR file imports and so it can even be imported itself.
A separate 'Update
Weather' button has been added to the Weather dialog, the OK button
will no longer force an update of the weather and can now be used to
just save any changes, such as any new destination or alternate airfield
designations. The maximum weather update distance is now limited to
160km.
The specified destination and alternate
airfield weather is now updated automatically without the need to
constantly download new METAR reports. These automatic updates ensure
compliance with the current downloaded METAR reports at these locations.
This is ideally suited to all flyers, low and slow, and high and fast
types. Just remember to configure your destination and alternates and
leave the rest to the LWE.
A forced recovery
altitude has been added (default 8000 feet) to allow full recovery of
the reported surface winds after wind stabilisation and during the final
descent phase.
We are hoping to release the new beta either tomorrow or over the weekend.

P.S. Refering to the above list ...
Wind smoothing - Improved and now excludes destination and alternate airfields.
Wind Stabilisation - recovery improved with forced recovery option at lower altitude.
Inaccuracies of FSX wind direction - will sort this out in the futture when we map the globe.
No recent weather update - now done all automatically for your destination and alternates.
No destination ICAO code specified - that's up to you but you can edit without generating new weather.
We're getting there ...
