...MORE UNSETTLED WEATHER MOVING ACROSS THE WESTERN U.S. THROUGH  
SATURDAY...  
   
..STRONG THUNDERSTORMS FORECAST FOR TEXAS FRIDAY INTO SATURDAY
 
 
...RAIN MOVING ACROSS THE EASTERN U.S. FRIDAY WITH WINTRY WEATHER  
FOR NORTHERN NEW ENGLAND FRIDAY NIGHT...  
 
A SERIES OF SYSTEMS OVER THE NORTHEAST PACIFIC WILL CONTINUE TO  
BRING UNSETTLED WEATHER ACROSS A LARGE PORTION OF THE WESTERN U.S.  
INTO THE WEEKEND AS THEIR ATTENDANT FRONTAL SYSTEMS MOVE THROUGH  
THE REGION. THIS WILL KEEP A GOOD CHANCE OF RAIN ALONG THE WEST  
COAST THROUGH THE WEEKEND, AS HIGHER ELEVATION SNOW AND LOWER  
ELEVATION RAIN SPREAD ACROSS THE INTERMOUNTAIN AND GREAT BASIN,  
FOLLOWED BY THE NORTHERN AND CENTRAL ROCKIES FRIDAY AND SATURDAY.  
THE HEAVIEST PRECIPITATION OVER THE NEXT FEW DAYS IS EXPECTED TO  
FALL FROM NORTHERN CALIFORNIA NORTHWARD THROUGH THE COASTAL RANGES  
AND CASCADES OF OREGON AND WASHINGTON, WITH LESSER AMOUNTS  
ELSEWHERE ACROSS THE INTERMOUNTAIN WEST. FLOOD WATCHES HAVE BEEN  
POSTED ACROSS PORTIONS OF THIS AREA. AS THE FIRST IN THE SERIES  
OF SYSTEMS MOVES TOWARDS THE PLAINS, RAIN AND THUNDERSTORMS ARE  
EXPECTED TO OVERSPREAD THE CENTRAL AND NORTHERN PLAINS FROM FRIDAY  
NIGHT THROUGH SATURDAY.  
 
MEANWHILE, AN UPPER-LEVEL DISTURBANCE WILL PUSH ACROSS NORTHERN  
MEXICO ON FRIDAY, ENTERING THE SOUTHERN PLAINS ON SATURDAY. THIS  
WILL LEAD TO THE ONSET OF THE DRYLINE AND BRING THE NEXT ROUND OF  
THUNDERSTORMS INTO THE SOUTHERN PLAINS, SOME OF WHICH MAY BE  
SEVERE OVER TEXAS FRIDAY INTO SATURDAY. SCATTERED THUNDERSTORMS  
ARE ALSO EXPECTED TO DEVELOP FARTHER NORTH OVER THE NORTHERN AND  
CENTRAL PLAINS ON SATURDAY AS ANOTHER COLD FRONT APPROACHES FROM  
THE NORTH. MEANWHILE, SCATTERED THUNDERSTORMS CAN ALSO BE  
EXPECTED IN THE SOUTHEAST THROUGH THE NEXT COUPLE OF DAYS DUE TO A  
FRONT LANGUISHING ACROSS THE REGION.  
 
MOISTURE ASSOCIATED WITH WAVES OF LOW PRESSURE MOVING ACROSS THE  
SOUTH AND OHIO VALLEY AND AN ASSOCIATED DISTURBANCE ALOFT WILL  
SPREAD RAIN EASTWARD, MOVING THROUGH THE EAST ON FRIDAY. WITHIN  
ITS NORTHERN PERIPHERY, SNOW IS EXPECTED TO MOVE ACROSS NORTHERN  
NEW ENGLAND. THE PRECIPITATION SHOULD BEGIN TO GRADUALLY MOVE OFF  
THE EAST COAST ON SATURDAY AS A LOW PRESSURE CENTER IS FORECAST TO  
MOVE OUT OF NORTH CAROLINA AND OUT TO SEA.
