SUBTROPICAL STORM ALBERTO WILL CONTINUE A NORTHERLY TRACK THROUGH  
THE EASTERN GULF OF MEXICO OVER THE NEXT FEW DAYS, AND BASED ON  
THE LATEST ADVISORY FROM THE NATIONAL HURRICANE CENTER, IS  
EXPECTED TO MAKE LANDFALL ALONG THE CENTRAL GULF COAST BY MONDAY  
NIGHT. IN THE MEANTIME, SIGNIFICANT MOISTURE WILL CONTINUE BEING  
PULLED NORTHWARD ACROSS FLORIDA, THE CENTRAL GULF COAST, AND INTO  
MUCH OF THE SOUTHEAST THIS WEEKEND AND INTO THE EARLY WORK WEEK.  
IN ADDITION TO THE SOUTHEASTERN AND GULF COAST STATES, HEAVY  
RAINFALL WILL ALSO BE POSSIBLE ACROSS THE CENTRAL APPALACHIANS AND  
INTO THE MID-ATLANTIC STATES, AS MULTIPLE WAVES OF ENERGY MOVE  
THROUGH IN THE BROAD MID-UPPER LEVEL TROUGHING SURROUNDING  
ALBERTO. A SLIGHT TO MODERATE RISK FOR EXCESSIVE RAINFALL/FLASH  
FLOODING IS HIGHLIGHTED IN WPCS EXCESSIVE RAINFALL OUTLOOKS ACROSS  
MUCH OF THE SOUTHEAST, WITH A MARGINAL TO SLIGHT RISK EXTENDING  
NORTHWARD INTO THE MID-ATLANTIC TONIGHT AND ON SUNDAY. AS IS  
USUALLY THE CASE WITH TROPICAL SYSTEMS, THERE IS ALSO A MARGINAL  
RISK FOR SEVERE WEATHER AND TORNADOES, PARTICULARLY FOR FLORIDA  
AND PORTIONS OF THE EASTERN/CENTRAL GULF COAST. FOR THE LATEST  
INFORMATION ON THE TRACK AND INTENSITY OF ALBERTO, PLEASE REFER TO  
THE NATIONAL HURRICANE CENTER (WWW.HURRICANES.GOV).

CONTINUE TO EXPAND ACROSS PORTIONS OF THE INTERMOUNTAIN WEST  
TONIGHT, AND INTO THE PLAINS SUNDAY AND MONDAY. A SURFACE LOW AND  
COLD FRONT MOVING SLOWLY EASTWARD INTO THE HIGH PLAINS SHOULD HELP  
PROVIDE A FOCUS FOR HEAVY RAINFALL AND POSSIBLE SEVERE WEATHER.  
THE SPC HAS HIGHLIGHTED MUCH OF THE NORTHERN AND CENTRAL PLAINS  
WITHIN A MARGINAL TO SLIGHT RISK FOR SEVERE WEATHER TONIGHT AND  
INTO MONDAY. BY MONDAY, STORMS WILL ALSO DEVELOP ALONG A FRONTAL  
BOUNDARY AS IT DROPS INTO THE NORTHERN MISSISSIPPI VALLEY. AHEAD  
OF THIS SYSTEM, TEMPERATURES WILL BE VERY WARM ACROSS MUCH OF THE  
CENTRAL U.S. AND THE MID-WEST WITH AFTERNOON HIGH TEMPERATURES AS  
MUCH AS 10 TO 20 DEGREES ABOVE NORMAL POSSIBLE.
