.DISCUSSION...Areas of dense fog have developed across the Central
Savannah River Area this morning. May start to see some
improvement to visibilities around 9am, but expect fog to lift by
10 am. High pressure and the upper level ridge which have
provided well above normal temperatures will remain over the
region today then begin moving east of the area tonight. Do not
expect any showers at the burn location today and tonight as most
of the activity should remain mainly northwest of the area closer
to the more favorable moisture, instability, and lift. The chance
for fog will be lower on Sunday morning due to a 30 knot low level
jet developing and increased cloud cover. A cold front will move
into the area on Sunday bringing increased chances of showers.
