..IKE CONTINUES TO PRODUCE DAMAGING WINDS AND HEAVY RAINS
THE FORWARD MOTION OF IKE HAS BEEN AND WILL CONTINUE TO BE
IMPRESSIVE.THE REMNANTS OF IKE ARE FORECAST TO RAPIDLY MOVE
NORTHEASTWARD ACROSS THE GREAT LAKES AND INTO CANADIAN TERRITORY.
THE HEAVIEST PRECIPITATION WILL BE NORTH AND WEST OF THE SURFACE
LOW. MEANWHILE...IN THE WARM SECTOR...EXPECT STRONG WINDS.
EXTRATROPICAL IKE WILL CONTINUE TO DELIVER INTENSE AND DANGEROUS
WINDS THAT WILL IMPACT THE OHIO VALLEY...EASTERN GREAT LAKES AND
ST LAWRENCE RIVER VALLEY REGIONS. FOR MORE INFORMATION ON THE
THREAT OF WINDS IN YOUR AREA OR THE CONDITIONS ON LAKE ERIE AND
LAKE ONTARIO...PLEASE REFER TO THE LOCAL NWS FIELD OFFICE. WHILE
THE BULK OF TROPICAL MOISTURE WILL MOVE NORTH OF THE U.S./CANADIAN
BORDER TONIGHT...THE FRONTAL ZONE SPANNING ACROSS THE TENNESSEE
VALLY AND WESTERN GULF COAST REGION...WILL CONTINUE TO SUSTAIN
CONVECTION. MOST OF THE CONVECTION WILL BE SCATTERED ALONG THE
SOUTHERN PORTION OF THE BOUNDARY...HOWEVER...LINEAR THUNDERSTORMS
AT THE EDGE OF THE BOUNDARY MAY DEVELOP AND PROPAGATE ACROSS
MISSISSIPPI AND ALABAMA. MONDAY AND TUESDAY AFTERNOON...THE
SOUTHEAST WILL SEE SCATTERED THUNDERSTORMS FIRE-UP AGAIN...AS
DIURNAL HEATING ACTS UPON AN ALREADY BUOYANT AIRMASS.
ADDITIONALLY...THE SOUTHERN TIP OF TEXAS CAN ANTICIPATE
THUNDERSTORMS.
ELSEWHERE...POST IKE...MUCH OF THE CONUS WILL BE RELATIVELY QUIET.
UPPER LEVEL RIDGING OVER THE INTERMOUNTAIN WEST WILL RESULT IN
WIDESPREAD SUBSIDENCE...WHICH WILL DRY THE ATMOSPHERE AND ENABLE
TEMPERATURES TO INCREASE. BY TUESDAY MORNING...A DEVELOPING COLD
FRONT WILL MOVE INTO THE CANADIAN PRAIRIE...ENABLING TEMPERATURES
TO DROP 15-20F AFTER THE FRONTAL PASSAGE. THIS COOLER AIRMASS
WILL PREDOMINATELY IMPACT CENTRAL CANADA THIS FORECAST
PERIOD...HOWEVER...COLD AIR WILL EVENTUALLY ADVECT INTO THE
NORTHERN PLAINS OF THE U.S..
