...SEASONABLY COOL WITH GUSTY WINDS FOR NEW ENGLAND TODAY IN WAKE  
OF DEPARTING STORM SYSTEM...  
 
...SEVERE THUNDERSTORMS AND FLASH FLOODING WILL BE POSSIBLE FOR  
PORTIONS OF THE SOUTHERN PLAINS ON WEDNESDAY...  
 
RELATIVELY QUIET WEATHER WILL BE IN STORE FOR THE LOWER 48 TODAY  
AS THE NATION WILL BE BETWEEN STORM SYSTEMS. A STRONG LOW PRESSURE  
CENTER IN THE GULF OF SAINT LAWRENCE WILL CONTINUE TO SLOWLY TRACK  
OFF TOWARD THE EAST THROUGH TONIGHT. THE MAIN AFFECT OF THIS  
SYSTEM ON WEATHER IN NEW ENGLAND WILL BE FOR GUSTY WINDS TODAY  
WITH PEAK GUSTS IN THE 25 TO 35 MPH RANGE. SCATTERED RAIN AND SNOW  
SHOWERS WILL ALSO BE FOUND ACROSS FAR NORTHERN NEW ENGLAND WITH  
SEASONABLY COOL TEMPERATURES.  
 
THE OTHER SYSTEM IS CURRENTLY MOVING MOVING ACROSS THE WEST COAST  
THIS MORNING AND WILL CONTINUE TO MOVE EAST THROUGHOUT THE DAY.  
EXPECT PERIODS OF STEADY RAIN AND HIGHER ELEVATION SNOW FOR THE  
INTERMOUNTAIN WEST INTO TONIGHT. A PORTION OF THE UPPER LEVEL  
SYSTEM WILL TRACK SOUTHEASTWARD ACROSS THE SOUTHWEST TONIGHT WHILE  
STRENGTHENING WITH A NORTHERN PORTION MOVING INTO THE NORTHERN  
PLAINS. CONDITIONS WILL BE FAVORABLE FOR THE DEVELOPMENT AND  
SPREADING OF WILDFIRES TODAY FROM EASTERN NEW MEXICO INTO FAR  
WESTERN TEXAS ON THE DRY SIDE OF A DRYLINE GIVEN A COMBINATION OF  
LOW RELATIVE HUMIDITIES AND GUSTY WINDS.  
 
SCATTERED SHOWERS AND THUNDERSTORMS WILL BREAK OUT OVERNIGHT  
TONIGHT FROM NEBRASKA/SOUTH DAKOTA EASTWARD TOWARD THE UPPER  
MIDWEST TO THE NORTH OF A WARM FRONT AND ADVANCING LOW PRESSURE  
CENTER TRACKING TOWARD WISCONSIN. FARTHER SOUTH, A ROUND OF STRONG  
TO SEVERE THUNDERSTORMS IS EXPECTED FROM KANSAS AND OKLAHOMA DOWN  
INTO TEXAS FOR WEDNESDAY. THE STORM PREDICTION CENTER IS  
FORECASTING AN ENHANCED RISK FOR SEVERE STORMS ON WEDNESDAY FROM  
SOUTHEASTERN OKLAHOMA INTO FAR WESTERN ARKANSAS AND INTO NORTHERN  
AND CENTRAL TEXAS. A SLIGHT RISK EXTENDS AS FAR NORTH AS IOWA.  
HEAVY RAIN WILL ALSO BE POSSIBLE FROM THESE STORMS WITH A SLIGHT  
RISK FOR FLASH FLOODING IN PLACE FROM EASTERN TEXAS INTO WESTERN  
LOUISIANA AND MUCH OF ARKANSAS. SOME OF THESE SAME LOCATIONS  
EXPERIENCED HEAVY RAIN OVER THE PAST WEEK AND COULD BE MORE  
SENSITIVE TO FLOODING FROM ADDITIONAL HEAVY RAIN FROM THE UPCOMING  
STORM SYSTEM.  
 
REGARDING TEMPERATURES, IT WILL BE FAIRLY WARM AHEAD OF THE  
WESTERN STORM SYSTEM TO AFFECT THE GREAT PLAINS, WITH HIGH  
TEMPERATURES TODAY IN THE 70S AND 80S FROM THE CENTRAL AND  
SOUTHERN HIGH PLAINS, THROUGH THE MIDWEST AND TO THE MID-ATLANTIC  
AND SOUTHEAST BOTH TODAY AND WEDNESDAY. COOLER THAN AVERAGE  
TEMPERATURES WILL BE SEEN IN THE WAKE OF THE STORM SYSTEM, OVER  
MUCH OF THE WEST TODAY AND INTO THE FOUR CORNERS REGION FOR  
WEDNESDAY.
