DISCUSSION

NOT MUCH CHANGE SINCE THE LAST FORECAST. MOSTLY DRY WEATHER INTO
THE WEEKEND EXCEPT FOR A SLIGHT CHANCE OF A LIGHT SHOWER TOMORROW
NIGHT IN SOUTHWEST VIRGINIA. THIS WEEKEND, A WEAK FRONT BRINGS
MORE LIGHT RAIN CHANCES SATURDAY NIGHT INTO SUNDAY MORNING, BUT
WITH NO REAL PUSH OF COLD AIR BEHIND IT. THE BIGGEST IMPACT FROM
THIS WEEKEND'S SYSTEM WILL BE THE BREEZY WINDS THAT WILL ACCOMPANY
IT THANKS TO A 30 TO 40KT 850MB JET THAT WILL BE MOVING ACROSS
THE AREA. DEEP MIXING WILL ALLOW BREEZY CONDITIONS ACROSS VALLEY
LOCATIONS, LOWER ELEVATIONS, OF 15 TO 20 MPH WIND GUSTS ON
SATURDAY AND SUNDAY. THE HIGHER ELEVATIONS OF THE EAST TN
MOUNTAINS WILL SEE GUSTS FROM 30 TO 40 MPH. MOST HIGHER ELEVATION
AREAS WILL STAY BELOW ADVISORY LEVEL WINDS BUT ISOLATED LOCATIONS
SUCH AS COVE MOUNTAIN MAY SEE GUSTS ABOVE 40 MPH.
A PATTERN SHIFT NEXT WEEK IS STILL EXPECTED BUT TIMING REMAINS
UNCERTAIN IN REGARDS TO WHEN A SYSTEM WILL IMPACT OUR AREA. BOTTOM
LINE, INCREASING RAIN PROBABILITIES ARE EXPECTED NEXT WEEK BUT KEEP
AN EYE OUT FOR FURTHER DETAILS ONCE MODELS BETTER RESOLVE THEIR
TIMING DIFFERENCES.
