Region 9S Weather

[Mike the Strike]

Those 44-odd pilots participating in the Region 9S contest at El Tiro
Gliderport next week might be interested in the long-range weather
forecast. Although El Nino isn't quite dead yet, it is expected that
the more southerly passage of weather systems and fronts that has
brought us some spectacular soaring recently will abate, at east for
the early part of the contest. Long range forecasts are predicting
high temperature in the upper 80s and overnight lows in the 60s and an
overall drier trend than of late. This should give us our typical
spring soaring conditions - mostly blue thermals with a decent working
band of at least 5,000 to 7,000 feet AGL. The odd brush-by of a front
may inject some moisture and give us a day or two of cumulus.

With its recent rediscovery by cross-country pilots and a resurgence
of new young pilots at Tucson Soaring club, El Tiro has produced some
great flights in the last year or two. It is currently the only US
club in the top ten of OLC, with over 50,000 km flown to date.

We hope the visitors to Region 9 will get to experience some of our
great conditions next week.

Update... temperatures Saturday through Monday will be about normal,
with highs in the low 90s under the influence of high pressure. Good
blue soaring. A cold front is expected to approach Tuesday and pass
through Wednesday (a bit early for precise timing). If it's like the
last one we just had, it should bring enough moisture for cumulus for
a couple of days in the middle of the contest and some honking good
soaring. White hat will be on standby!

Update:

Temperatures have climbed close to the century mark in the past day or
two, but will drop back down to the mid nineties by the start of
Region 9. Forecasts are now showing both low pressure systems and
fronts will impact southern Arizona Monday through Wednesday. These
will increase winds on the first few task days but are also forecast
to increase moisture and should provide good cumulus through the mid
part of the week.
