***ODILE ORDEAL FOR THE DESERT SOUTHWEST THIS WEEK***

***FALL-LIKE WEATHER CONTINUES ACROSS MUCH OF THE EASTERN U.S.***

***SCATTERED SHOWERS AND STORMS FOR THE GULF COAST***


THE BIG THING MAKING WEATHER HEADLINES THROUGH THE MIDDLE OF THE
WEEK WILL BE THE MOISTURE ASSOCIATED WITH THE REMNANTS OF TROPICAL
STORM ODILE.  THIS ONCE POWERFUL HURRICANE OVER THE BAJA
CALIFORNIA PENINSULA IS NOW WEAKENING, HOWEVER THERE IS A PLETHORA
OF TROPICAL MOISTURE JUST SOUTH OF THE MEXICO BORDER THAT IS
FORECAST TO AFFECT THE DESERT SOUTHWEST.  WIDESPREAD FLASH FLOOD
WATCHES ARE IN EFFECT FROM SOUTHERN NEVADA TO EXTREME WESTERN
TEXAS.  ALTHOUGH THE HEAVIEST RAINFALL IS EXPECTED OVER NORTHWEST
MEXICO, THERE MAY BE SOME LOCATIONS IN ARIZONA AND NEW MEXICO THAT
RECEIVE IN EXCESS OF FOUR INCHES OF RAIN THROUGH FRIDAY MORNING.
THIS IS MORE THAN A MONTH`S WORTH OF RAINFALL!

IN THE WARM AND HUMID AIRMASS NEAR THE GULF COAST AND FLORIDA,
THERE WILL BE SCATTERED SHOWERS AND THUNDERSTORMS, ESPECIALLY
DURING THE AFTERNOON HOURS.  LOCALLY HEAVY RAINFALL WILL BE
POSSIBLE NEAR THE TEXAS COAST AND SOUTH FLORIDA, AND ANOTHER AREA
OF CONCENTRATED RAINFALL IS LIKELY NEAR MISSOURI.  SHOWERS ARE
ALSO LIKELY ACROSS PARTS OF THE GREAT LAKES AND NORTHERN NEW
ENGLAND AS A COLD FRONT CLIPS THE NORTHERN BORDER OF THE U.S.
ELSEWHERE, A LARGE SURFACE HIGH IS CONTROLLING THE WEATHER PATTERN
ACROSS MUCH OF THE EASTERN U.S., WITH MANY STATES ENJOYING QUALITY
FALL-LIKE CONDITIONS.
