.DISCUSSION...
Another dry and warm day is expected at the burn site today,
although high-level clouds will continue to increase ahead of an
approaching storm system. Low-level southeasterly flow will also
strengthen throughout the day in advance of this system. Regardless
of the increase in cloud cover, afternoon temperatures around 75
degrees will result in RH values of 35-40%. Southeasterly winds will
remain elevated and even increase a bit overnight, and this coupled
with warm overnight temperatures should prevent concern for fog
development. Light rain will begin to spread across the region early
tomorrow morning as the previously mentioned storm system approaches
the TN valley.
