VALID 00Z SUN NOV 01 2009 - 12Z MON NOV 02 2009
THE HEAVY RAIN ASSOCIATED WITH THE COLD FRONT NOW STRETCHING FROM
THE FLORIDA PANHANDLE NORTH NORTHEASTWARD INTO CANADA IS FINALLY
OVER. LIGHT TO MODERATE RAIN CONTINUES TO FALL ALONG THE FRONTAL
BOUNDARY AND WILL CONTINUE TO DIMINISH AS IT FINALLY MOVES OFF THE
ATLANTIC COAST LATE SUNDAY MORNING. AN AREA OF STRONG HIGH
PRESSURE IS PUSHING INTO THE EASTERN THIRD OF THE U.S. BEHIND THIS
FRONTAL SYSTEM. IT WILL BRING COOLER AND DRIER CONDITIONS WITH IT
FOR THE BEGINNING OF THE WORK WEEK.
ANOTHER SYSTEM IS RAPIDLY PUSHING THROUGH THE INTERMOUNTAIN WEST
INTO THE CENTRAL PLAINS. UNLIKE ITS PREDECESSORS...THIS SYSTEM IS
NOT EXPECTED TO PRODUCE LARGE SWATHS OF HEAVY RAIN OR SNOW. A
STRONG HIGH SITUATED OVER THE SOUTHERN PLAINS AND SOUTHERN
MISSISSIPPI VALLEY WILL BLOCK MOISTURE RETURN FLOW FROM THE GULF
OF MEXICO KEEPING PRECIPITATION LIMITED TO THE NORTHERN TIER OF
THE U.S.. THERE WILL NOT BE A STRONG TEMPERATURE DROP WITH THE
PASSAGE OF THIS FRONT.
STRONG HIGH PRESSURE FROM THE PACIFIC WILL BE BUILDING INTO THE
WESTERN U.S. AS THE WEEKEND PROGRESSES. AFTER A BRUTALLY COLD
STINT FOLLOWING A COLD FRONTAL PASSAGE LAST WEEK...MUCH OF THE
WEST WILL EXPERIENCE A RISE IN TEMPERATURE. AREAS IN THE NORTHERN
MOST WESTERN STATES MAY COME CLOSE TO REACHING THE 60 DEGREE MARK
ON MONDAY.
