.DISCUSSION...
An early morning cold front from the northwest brings wetting rain
chances (about 50%) between 0500L and 0900L. A northwest shift in
wind occurs as well with the frontal passage. Much cooler today,
with a high around 10 degrees lower than yesterday. An afternoon
west wind increases, with gusts around 20 mph.
Difficult rain forecast after the frontal passage this morning.
Models are showing the best rain chances late morning and
afternoon remaining north of the site, but not by too much.
Chances are about 15% to 20% at the site for the late
morning and afternoon today, but could be higher if rain
occurs slightly more south than models are projecting. This
chance of rain lasts until about midnight tonight. Tuesday looks
similarly cool, with a less than 10% chance of rain.
