Area forecast discussion, Feb 24, 2:25 PM EST, 51 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
225 PM EST SAT FEB 24 2007
.SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...CURRENT SURFACE
ANALYSIS SHOWS A LOW PRESSURE SYSTEM STRENGTHENING OVER THE
PLAINS...WITH HIGH PRESSURE ENTRENCHED ALONG THE EASTERN SEABOARD.
MODELS ARE IN GENERAL AGREEMENT WITH THE PROGRESSION OF THIS LOW
PRESSURE SYSTEM TONIGHT...WITH THE BULK OF THE PRECIP NOT EXPECTED
UNTIL AFTER MIDNIGHT AND PROBABLY MORE TOWARDS SUNRISE. WRF MODEL
CONTINUES TO INDICATE THAT THE COLD FRONT WILL NOT COMPLETELY EXIT
THE FORECAST AREA UNTIL LATE SUNDAY AFTERNOON. THIS SEEMS REASONABLE
TO EXPECT SINCE A STRONG UPPER-LEVEL TROUGH OVER THE PLAINS WILL
BECOME NEGATIVELY-TILTED TONIGHT...LIKELY RESULTING IN A SLOWER
EASTWARD PROGRESSION OF THIS SYSTEM. BOTH MODELS CONTINUE TO DEVELOP
A STRONG 850 MB JET (BETWEEN 50 AND 70 KTS) AFTER MIDNIGHT
TONIGHT...AND WILL PLAN TO ISSUE A WIND ADVISORY (AND HIGH WIND
WARNING ACROSS THE MOUNTAINS) TO ACCOUNT FOR THE POSSIBILITY OF
THESE STRONG WINDS DESCENDING DOWN INTO THE VALLEYS BY CONVECTION
LATER TONIGHT AFTER MIDNIGHT. STRONG WINDS WILL BE A CERTAINTY
ACROSS THE HIGHER ELEVATIONS ABOVE 2500 FEET...BUT HIGHER WINDS IN
THE VALLEYS WILL DEPEND ON HOW STRONG THE LINE OF CONVECTION LATER
TONIGHT REMAINS AS IT ENTERS THE FORECAST AREA. SURFACE-BASED
INSTABILITY AHEAD OF THIS COLD FRONT APPEARS WEAK AT BEST FOR THE
FORECAST AREA TONIGHT...BUT MODEL SOUNDINGS ARE INDICATING SOME
ELEVATED INSTABILITY. IN FACT...A LARGE AMOUNT OF ELECTRICAL
ACTIVITY HAS DEVELOPED WAY AHEAD OF THE COLD FRONT OVER THE WESTERN
TN RIVER VALLEY WHERE ELEVATED INSTABILITY RESIDES AS WELL...SO
THINK THAT THERE MAY BE A LITTLE MORE COVERAGE OF TSTORMS LATER
TONIGHT. SURFACE-BASED INSTABILITY INCREASES ON SUNDAY...ESPECIALLY
ACROSS NORTHEAST TN AND SOUTHWEST VA...AS THE COLD FRONT MOVES INTO
THE FORECAST AREA. WILL MENTION ADDITIONAL CONVECTIVE REDEVELOPMENT
ON SUNDAY...WITH SOME HAIL POSSIBLE SINCE THE FREEZING LEVEL WILL BE
LOW. HOWEVER...TSTORM COVERAGE ON SUNDAY AFTERNOON SHOULD BE MORE
SCATTERED IN COVERAGE.
.LONG TERM (TUESDAY THROUGH SATURDAY)...UPPER LOW TO OUR NORTH
SLOWLY PULLS AWAY FROM THE REGION ON TUESDAY WITH HIGH PRESSURE
BUILDING IN ON WEDNESDAY. TIMING OF NEXT SYSTEM REMAINS IN QUESTION
BUT SHOULD AFFECT THE AREA THURSDAY TO FRIDAY. WILL KEEP CHANCE POPS
FOR THIS PERIOD WITH THE HIGHEST CHANCE THURSDAY NIGHT. PRECIP
SHOULD BE ALL RAIN BUT AIR MASS DOES BECOME SLIGHTLY UNSTABLE AND
MAY NEED TO ADD THUNDER AS DETAILS BECOME MORE CLEAR WITH FUTURE
MODEL RUNS. STAYED NEAR GUIDANCE FOR TEMPERATURES THROUGHOUT.
