MOISTURE ASSOCIATED WITH THIS FEATURE...BUT WILL STILL INDICATE A
CHANCE OF PRECIPITATION IN THE WHITE MOUNTAINS AND EAST OF TUCSON
SUNDAY. THE WIND ALONG WITH LOW MINIMUM RELATIVE HUMIDITIES WILL BE
THE MAIN CONCERNS SUNDAY AS THE SHORTWAVE TROUGH PASSES THROUGH.
BASED ON PROJECTED VALUES...WILL POST A FIRE WEATHER WATCH FOR MUCH

THIS PRODUCT FOR MORE DETAILS.

HIGH PRESSURE ALOFT WILL BUILD IN BEHIND THE SHORTWAVE TROUGH MONDAY
INTO THE MID WEEK. THIS SHOULD RESULT IN DRY CONDITIONS WITH A
