MEXICO...

...ABOVE AVERAGE TEMPERATURES EXPECTED FOR THE EASTERN TWO-THIRDS
OF THE COUNTRY...

MONSOONAL MOISTURE ACROSS THE SOUTHWESTERN U.S. WILL RESULT IN
SCATTERED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS THROUGH
THE NEXT COUPLE DAYS. MOISTURE AND RAINFALL RATES MAY BE
SUFFICIENT THIS EVENING TO PRODUCE ISOLATED AREAS OF FLASH
FLOODING ACROSS EASTERN PORTIONS OF ARIZONA AND WESTERN PORTIONS
OF NEW MEXICO.

A COLD FRONT OF PACIFIC ORIGIN IS MOVING ACROSS THE NORTHERN
INTERMOUNTAIN WEST TODAY. THIS FRONT WILL BEGIN TO MOVE INTO THE
NORTHERN PLAINS BY EARLY THURSDAY MORNING, WHILE THE TRAILING END
OF THE FRONT BECOMES STATIONARY ACROSS THE INTERMOUNTAIN WEST.
THIS FRONT WILL BRING SHOWERS AND THUNDERSTORMS TO NORTHERN
PORTIONS OF THE INTERMOUNTAIN WEST ON THURSDAY, WITH SHOWERS AND
THUNDERSTORMS POSSIBLE ACROSS THE NORTHERN PLAINS THURSDAY NIGHT
AND THE UPPER MIDWEST BY FRIDAY AFTERNOON. BEHIND THE COLD FRONT,
TEMPERATURES WILL 10 TO 20 DEGREES BELOW AVERAGE ACROSS MUCH OF
THE PACIFIC NORTHWEST AND PORTIONS OF THE NORTHERN INTERMOUNTAIN
STATES ON THURSDAY AND FRIDAY.

A COLD FRONT WILL MOVE SOUTHWARD FROM CANADA INTO THE LOWER GREAT

HIGH PRESSURE AT THE MID AND UPPER-LEVELS OF THE ATMOSPHERE WILL
PROMOTE ABOVE AVERAGE TEMPERATURES ACROSS MUCH OF THE EASTERN
TWO-THIRDS OF THE NATION. THE MOST SIGNIFICANT ABOVE AVERAGE
TEMPERATURES WILL OCCUR FROM  THE NORTHERN PLAINS TO PORTIONS OF
THE NORTHEAST AND MID-ATLANTIC WHERE TEMPERATURES OF 5 TO 15
DEGREES ABOVE AVERAGE ARE EXPECTED. TEMPERATURES MAY APPROACH 20
DEGREES ABOVE AVERAGE ACROSS THE DAKOTAS ON THURSDAY.
