.DISCUSSION...Winds will increase a bit today ahead of an
approaching weather disturbance. Lingering moisture and increasing
instability will also allow for scattered showers and
thunderstorms to develop over and near the burn site this
afternoon. Gusty outflow winds will be the biggest threat. While
outflow winds will be erratic in direction, east to southeasterly
will be favored as storms are expected to develop along the higher
ridgeline to the east. The stronger storms and training of storms
will bring a potential for localized wetting rain, although this
will be hit or miss for the burn site itself. A weak cold front
will sag into the area tomorrow. This will bring a slight cooling
trend and a more northerly component to winds for tomorrow.
Isolated showers and thunderstorms remain possible for tomorrow,
although this comes with a decreased chance of wetting rain as the
airmass starts to trend drier. Warm and dry conditions can then be
expected for the midweek timeframe.
