Rainy Friday; Watching for Storms Late Friday Night

Rain is on the way to North Carolina early this morning, and we are still looking for a good soaking this afternoon, tonight, and into early Saturday. We should be on track to pick up between 1" and 2" of rain during that period. Of course, that rain is much needed, but we are still somewhat concerned about the potential for severe weather overnight. The National Weather Service outlines the severe weather threat in their hazardous weather outlook posted below....

415 AM EST FRI MAR 7 2008

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL NORTH CAROLINA

..DAY ONE...TODAY AND TONIGHT....

THERE IS A RISK OF SEVERE THUNDERSTORMS LATE TONIGHT INTO SATURDAY MORNING ACROSS CENTRAL NORTH CAROLINA...

WIDESPREAD RAIN IS EXPECTED ACROSS CENTRAL NORTH CAROLINA TODAY. THIS WILL BE ASSOCIATED WITH A LEAD SURFACE WAVE THAT WILL CROSS THE REGION BY EARLY EVENING. THE RAIN IS EXPECTED TO TAPER OFF LATE TODAY AS THIS SYSTEM MOVES PAST. THERE IS A CHANCE OF SOME EMBEDDED THUNDERSTORMS TODAY... BUT THE CHANCE OF SEVERE THUNDERSTORMS IS EXPECTED TO BE LIMITED TO THE IMMEDIATE COAST... WHERE A COASTAL TROUGH WILL BE PRESENT

..DAYS TWO THROUGH SEVEN... SATURDAY THROUGH THURSDAY....

THERE IS A RISK OF SEVERE THUNDERSTORMS LATE TONIGHT INTO MID DAY SATURDAY ACROSS CENTRAL NORTH CAROLINA...

...STRONG GRADIENT WESTERLY WINDS EXPECTED BEHIND THE FRONT SATURDAY AFTERNOON...

THE MAIN STORM SYSTEM IS EXPECTED TO MOVE NORTHEAST ACROSS WESTERN NORTH CAROLINA LATE TONIGHT AND SATURDAY MORNING. THE TRAILING COLD FRONT WILL ACCELERATE OFF THE MOUNTAINS ACROSS CENTRAL NORTH CAROLINA SATURDAY MORNING AND EARLY AFTERNOON. THE WIND FIELD ALOFT... COUPLED WITH THE POTENTIAL FOR INCREASINGLY UNSTABLE AIRMASS NEAR THE SURFACE SUPPORT THE POTENTIAL DEVELOPMENT OF SEVERE THUNDERSTORMS. THE POTENTIAL FOR SEVERE THUNDERSTORMS WOULD INCREASE SIGNIFICANTLY LATE TONIGHT AND SATURDAY IF ENOUGH INSTABILITY CAN RETURN JUST IN ADVANCE OF THE STRONG COLD FRONTAL PASSAGE. IF THIS OCCURS... A SQUALL LINE ALONG OR JUST AHEAD OF THE COLD FRONT WOULD BE LIKELY... WITH THE POTENTIAL FOR WIDESPREAD DAMAGING WIND GUSTS TO 60 MPH.

IN ADDITION... STRONG WINDS WILL FOLLOW THE COLD FRONTAL PASSAGE SATURDAY AFTERNOON AND EARLY EVENING. THE WINDS WILL SHIFT TO THE WEST NORTHWEST BEHIND THE FRONT... AND INCREASE IN SPEED TO BETWEEN 20 AND 30 MPH... WITH GUSTS TO 45 MPH. THERE IS A POTENTIAL THAT THESE WINDS MAY NEED TO BE INCREASED IN LATER FORECASTS DUE TO THE STRENGTH OF THIS SYSTEM. IF SO... A WIND ADVISORY OR HIGH WIND WARNING MAY BE NEEDED FOR SATURDAY AFTERNOON. STAY TUNED.

PEOPLE ACROSS CENTRAL NORTH CAROLINA ARE ENCOURAGED TO STAY INFORMED OF THIS DEVELOPING WEATHER SITUATION. LISTEN FOR THE LATEST STATEMENTS FROM THE NATIONAL WEATHER SERVICE VIA NOAA WEATHER RADIO OR THE LOCAL MEDIA

..SPOTTER INFORMATION STATEMENT...

SKYWARN SPOTTER ACTIVATION MAY BE NEEDED LATE TONIGHT AND SATURDAY.SPOTTERS SHOULD STAY TUNED AND REPORT ANY SEVERE WEATHER.
