...WARM AND DRY TODAY WITH A CHANGE IN THE WEATHER TUESDAY AND WEDNESDAY...

.DISCUSSION...
AN UPPER LEVEL RIDGE OVER THE ROCKY MOUNTAINS WILL LINGER ONE MORE DAY TODAY
BRINGING ABOVE NORMAL TEMPERATURES AND LIGHT WINDS. LOW PRESSURE OFF THE COAST
PUSHES INTO NORTHERN CALIFORNIA TUESDAY AFTERNOON BRINGING SLIGHTLY COOLER
TEMPERATURE AND AN INCREASE IN CLOUDS.  MODEL DISAGREEMENT COMES INTO PLAY WEDNESDAY
AS SOME MODELS WANT TO TAKE THE BULK OF THE DYNAMICS AND THUS BETTER MOISTURE FURTHER
SOUTH INTO NEVADA...WHERE AS OTHER MODELS BRING IT MORE NORTH AND THAT WOULD BRING EVEN
BETTER CHANCES OF PRECIPITATION FOR THE BURN SITE. CURRENT THINKING IS TO GO WITH THE
FURTHER SOUTH MODELS AT THIS TIME. EITHER WAY...COOLER CONDITIONS AND CLOUDY SKIES
ARE EXPECTED FOR THE MIDDLE OF THE WEEK.
