Area forecast discussion, Mar 28, 1:27 PM CDT, 1 hour 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LITTLE ROCK AR 127 PM CDT FRI MAR 28 2014 .SHORT TERM...TONIGHT THROUGH MONDAY NIGHT... SFC FRONTAL BOUNDARY LIES ACROSS CENTRAL ARKANSAS AT THIS TIME...AND IS MOVING RATHER SLOWLY TO THE SOUTH. AN UPPER LEVEL SHORTWAVE IS APPROACHING FROM THE SW AND HELPING TO FIRE OFF CONVECTION THAT IS HEADED NEWD ACROSS THE STATE RIGHT NOW. AREA OF GREATEST CONCERN IS ACROSS THE SOUTHERN TWO OR THREE ROWS OF COUNTIES. SFC BASED DYNAMICS ARE NOT ALL THAT SPECTACULAR BUT THERE IS SUFFICIENT CAPE AND INSTABILITY TO WARRANT A CONCERN...PRIMARILY FOR HAIL...AND SECONDARILY FOR STRAIGHT LINE WIND DAMAGE. THERE HAS BEEN SOME BREAKS IN THE CLOUD COVER ACROSS THE SOUTH TODAY WHICH HAS ALLOWED TEMPERATURES TO CLIMB WELL INTO THE 70S WITH DEWPOINTS IN THE 60S. ALTHOUGH THE FOCUS WILL PRIMARILY BE ON THE SOUTHERN COUNTIES...HAIL COULD ALSO OCCUR FURTHER TO THE NORTH...INCLUDING AREAS NORTH OF THE FRONTAL BOUNDARY. WOULD NOT BE SURPRISED IF WE START TO GET A FEW REPORTS OF HAIL FROM THE EXISTING CONVECTION OVER THE NEXT FEW HOURS. SHORTWAVE SHOULD EXIT LATER TONIGHT AND THE SURFACE FRONT SHOULD PUSH THROUGH THE CWA ALLOWING HIGH PRESSURE TO BUILD IN OVER THE WEEKEND. BOTH SATURDAY AND SUNDAY SHOULD BRING FAIRLY PLEASANT WEATHER...AND RETURN SOUTHERLY FLOW SHOULD START TO SET IN BY SUNDAY NIGHT AS THE SFC HIGH MOVES TO THE EAST. IT LOOKS LIKE SIGNIFICANT SURFACE MOISTURE WILL NOT RETURN UNTIL LATE MONDAY. && .LONG TERM....MONDAY THROUGH THURSDAY. FORECASTS WILL CONTINUE REFLECT THE POTENTIAL FOR A POTENT FRONTAL SYSTEM TO AFFECT THE STATE DURING THE WED.- THU. TIME FRAME. TOO EARLY TO ADDRESS SPECIFIC SENSIBLE WEATHER ELEMENTS...HOWEVER THERE IS A POTENTIAL FOR ORGANIZED SEVERE STORMS DURING THIS PERIOD. NEAR NORMAL TEMPERATURES WILL PREVAIL THROUGH MOST OF THIS PERIOD...WITH A COOL SPELL EXPECTED LATE. && .PRELIMINARY POINT TEMPS/POPS...
