Spot Forecast for C-252 Growing...US Forest Service
National Weather Service Columbia SC
646 AM EDT Fri Apr 21 2017

Forecast is based on ignition time of 1000 EDT on April 21.
If conditions become unrepresentative...contact the National Weather
Service.

Positive or negative feedback including observations taken at
the burn site would be greatly appreciated. You can use the same
webpage where you requested the spot forecast for this. You may
also call our office if you have questions or concerns.

.DISCUSSION...A weak surface front will stall out well north and west
of the burn site later this afternoon.  Winds this morning will be out
of the south around 5 mph, then increasing as the inversion breaks to
around 10 mph with gusts over 16 mph possible through noon.  This is
due to a strong low-level jet between 1 and 2 kft this morning
that will begin to weaken early this afternoon.  Skies mostly sunny
through the day, with maybe some thin high cirrus, and then few to
scattered cu around 5 kft by this afternoon.  No fog threat this
morning.  Another low-level jet should set up again tonight, which
should help to inhibit any widespread fog formation.  Can not rule
out some patchy fog around areas of water, but confidence is low.
