VERY LITTLE HAS CHANGED REGARDING THE FORECAST FOR THE NEXT WEEK.
A LARGE HIGH PRESSURE RIDGE ACROSS THE SOUTHEAST WILL BE THE
DOMINANT FEATURE, PROVIDING DRY AND WARM CONDITIONS. A SERIES OF
LOW PRESSURE SYSTEMS WILL CROSS THE PLAINS AND GREAT LAKES, BUT
THE STRENGTH OF THIS RIDGE WILL PREVENT ANY PRECIP FROM REACHING
OUR AREA UNTIL PERHAPS LATE NEXT WEEK WHEN THE RIDGE SHIFTS OFF
THE ATLANTIC COASTLINE.
THE MAIN WEATHER CONCERN FOR THIS PERIOD WILL BE FIRE WEATHER
CONDITIONS. AS HIGH TEMPERATURES WARM INTO THE 80S, AFTERNOON RH
VALUES WILL DROP INTO THE 20S. WINDS WILL INCREASE TOMORROW TO
AROUND 10-15 MPH WITH GUSTS AROUND 20, THEN INCREASE AGAIN ON
MONDAY, 10-20 WITH GUSTS 25-30 MPH, AIDED BY CHANNELING OF SW
WINDS UP THE TN VALLEY. MONDAY WILL HAVE SOME CLOUD COVER, WHICH
MAY AID IN KEEPING RH VALUES FROM DROPPING BELOW 25%. FIRE
WEATHER INTERESTS SHOULD STAY AWARE OF THESE CONDITIONS SETTING UP
FOR SUNDAY AND MONDAY, AND POTENTIALLY TUESDAY AND WEDNESDAY AS
WELL.
HIGH TEMPERATURES WILL APPROACH OR EXCEED RECORDS NEXT WEEK. WE
MIGHT COME UP A FEW DEGREES SHORT OF RECORDS ON SUNDAY AND MONDAY,
BUT HIGHS IN THE RANGE OF 85 TO 90 WILL BE FORECAST FOR THE TN
VALLEY TUESDAY THROUGH FRIDAY. GIVEN THE DRY GROUND CONDITIONS,
IT WOULD NOT BE SURPRISING TO SEE TEMPERATURES HIGHER THAN THAT,
AS MODEL GUIDANCE MAY BE UNDERDOING DAYTIME TEMPERATURES.
