Spot Forecast for Clarks Fork 7-B...Grayback Forestry
National Weather Service MEDFORD OR
721 PM PDT Sun May 19 2024

Forecast is based on ignition time of 1100 PDT on May 20.
If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...High pressure and slightly dry conditions will
build in on Monday. But a trough on Tuesday will quickly disrupt
this. This will help keep recoveries high and winds out of the
west- northwest. I believe winds will decouple from the general
flow at ground level Monday night and will flow lightly down
drainages - this is reflected in the forecast below- but if it
doesn`t, winds would remain out of the north. Any rain recieved is
not expected to amount to more than 0.1 inch. Stronger winds are
expected on Wednesday.

P.s. Thanks for the obs and great burn site info!
