...LIGHT SNOW AND FREEING RAIN LIKELY TO TAPER OFF ACROSS PARTS OF  
NEW ENGLAND TONIGHT...  
 
...THE NEXT STORM SYSTEM WILL SPREAD HEAVY TO EXCESSIVE RAINFALL  
FROM THE LOWER MISSISSIPPI VALLEY INTO THE MID-ATLANTIC THIS  
WEEKEND...  
 
...HEAVY RAINFALL LIKELY ACROSS THE PACIFIC NORTHWEST COAST THIS  
WEEKEND...  
 
...MOST OF THE COUNTRY WILL EXPERIENCE ABOVE AVERAGE TEMPERATURES  
THIS WEEKEND WHILE THE SOUTHERN TIER REMAINS AT OR BELOW AVERAGE...  
 
A LOW PRESSURE SYSTEM STATIONED OVER THE NORTHEAST AND  
MID-ATLANTIC WILL MOVE OUT TO SEA TONIGHT. LIGHT SNOW SHOWERS AND  
SOME FREEZING RAIN WILL SLOWLY COME TO AN END AS A RESULT. IN THE  
MEANTIME, ANOTHER LOW PRESSURE SYSTEM WILL ORGANIZE OVER THE  
CENTRAL GULF COAST AND SPREAD A LINE OF THUNDERSTORMS, FOCUSED  
ALONG A COLD FRONT, ACROSS THE LOWER MISSISSIPPI VALLEY AND  
SOUTHEAST BEGINNING TONIGHT AND CONTINUING INTO SATURDAY. A BROAD  
SLIGHT RISK OF EXCESSIVE RAINFALL (LEVEL 2/4) IS IN EFFECT ACROSS  
THE CENTRAL GULF COAST WHERE MUCH OF THE REGION HAS HAD VIRTUALLY  
NO TIME TO RECOVER FROM THE DELUGE OF RAIN THEY'VE RECEIVED OVER  
THE PAST FEW DAYS.  
 
SOME CONVERGENCE OVER OKLAHOMA THIS AFTERNOON WILL SUPPORT THE  
PROPAGATION OF A WEAK COMPLEX OF STORMS ACROSS THE STATE TONIGHT  
BEFORE EVENTUALLY MERGING WITH THE GULF COAST SYSTEM AND PRODUCING  
SCATTERED SHOWERS AND THUNDERSTORMS TO ARKANSAS AND THE  
TENNESSEE/OHIO VALLEY ON SATURDAY. UPSLOPE ENHANCEMENT OF MOISTURE  
OVER THE SOUTHERN/CENTRAL APPALACHIANS COULD LEAD TO FLASH  
FLOODING CONCERNS ON SATURDAY AS FRONTALLY DRIVEN STORMS INTERACT  
WITH THE TERRAIN. THUS, A SLIGHT RISK OF EXCESSIVE RAINFALL IS IN  
EFFECT FOR THE SOUTHERN APPALACHIANS THROUGH PORTIONS OF THE  
CENTRAL APPALACHIANS/SOUTHWEST VIRGINIA ON SATURDAY.  
 
THIS SAME SYSTEM WILL SPREAD SHOWERS AND THUNDERSTORMS INTO THE  
SOUTHEAST AND MID-ATLANTIC COAST SATURDAY NIGHT INTO SUNDAY. COLD  
AIR IN PLACE OVER THE NORTHEAST WILL SUPPORT SOME LIGHT SNOW OVER  
THE INTERIOR AND SOME LIGHT FREEZING RAIN/SLEET OVER PARTS OF  
SOUTHERN NEW ENGLAND ON SUNDAY. CONDITIONS SHOULD BEGIN TO IMPROVE  
BY SUNDAY NIGHT.  
 
ELSEWHERE, A SERIES OF LOW PRESSURE SYSTEMS WILL DIRECT A  
CONTINUOUS STREAM OF MOISTURE INTO THE PACIFIC NORTHWEST THIS  
WEEKEND. ANYWHERE BETWEEN 1-4 INCHES OF RAIN IS POSSIBLE WITH  
ISOLATED HIGHER AMOUNTS OVER THE COASTAL RANGES AND CASCADES. A  
SLIGHT RISK IS IN EFFECT OVER THE COASTAL BORDER REGION OF OREGON  
AND CALIFORNIA WHERE SEVERAL INCHES OF RAINFALL MAY ACCUMULATE  
TONIGHT.  
 
HIGH PRESSURE OVER THE EAST AND WEST COASTS WILL GENERATE  
ANOMALOUS WARMTH FOR THOSE REGIONS THIS WEEKEND. THE UPPER LOW  
TRACKING ACROSS THE SOUTHERN TIER STATES WILL MODERATE  
TEMPERATURES WITH CLOUDY COOLER CONDITIONS COMPARED TO NORMAL.  
RECORD WARM LOW TEMPERATURES WILL BE POSSIBLE IN THE SOUTHEAST AND  
NORTHWEST TONIGHT. AS THE WEST CONTINUES TO WARM UP LATER THIS  
WEEKEND INTO EARLY NEXT WEEK, SO WILL THE POTENTIAL FOR WIDESPREAD  
RECORD BREAKING TEMPERATURES UP AND DOWN THE COAST.
