Updated Aviation Discussion

UPDATED AVIATION...06Z..Mostly VFR conditions to prevail through
the period. Smoke from the Cram fire will continue to spill into
sites RDM/BDN tomorrow, resulting in vsby and CIGs deteriorating
to MVFR or lower categories. Based on trends today, have reduced
vsby to 2SM-3SM for both sites around 20Z, with CIGs lowering
tonight, then increasing again by tomorrow afternoon. Otherwise,
all other sites will see clear skies. Winds will light, 12kts or
less, at all sites. Lawhorn/82


PREV DISCUSSION... /issued 219 PM PDT Tue Jul 15 2025/

SHORT TERM...today through Friday morning...

Satellite shows plumes of smoke from the Cram fire flowing into
Deschutes county and, to a lesser extent, Crook county. Winds
currently from the NE will shift more to the NNE/N in the later
afternoon hours, throwing some chances of smoke for the
Redmond/Bend area for the rest of the afternoon into the early
evening hours.

Temperatures are 5-15 degrees cooler than yesterday and will re-
enter a warming trend through the short term as a shortwave exits
the region. Mid-level winds in the synoptic pattern will pave for
some breezy conditions through the region. Combined with low RHs
and windy conditions, many parts of the region will see some
region of overlap (20-40% chance). Several fire weather zones in
Central OR will see decent coverage of overlap in Thursday. Given
that, we`ve issued Fire Weather Watches for ORZ696-698-703
Thursday afternoon into the evening hours.

LONG TERM...Friday morning through Tuesday...Fire weather
critical conditions continue through Friday as dry/windy
conditions. A little too far out to issue watches, but more than
likely will issue some watches for Friday in the next 12-24 hours.
SPC notes a 40% hatch over Central OR into much of the Basin for
Friday for critical fire conditions. A trough pattern re-appears
going into the weekend as a cold front is expected to enter the
region sometime Saturday, bringing back cooler temperatures,
wetter conditions, and less elevated fire conditions overall. Min
RH`s will recover as the cold front pattern starts, with values
between 20-30% for most of the area.
