THROUGH THE WEEK...
AN ARCTIC COLD FRONT IS SET TO MAKE ITS WAY THROUGH THE REGION
TONIGHT, WHICH WILL CAUSE TEMPERATURES TO TUMBLE AFTER SUNSET, ABOUT
3.5 DEGREES/HR, BOTTOMING OUT JUST ABOVE FREEZING TOMORROW MORNING.
RAIN IS EXPECTED ALONG AND AHEAD OF THIS FRONT AFTER MIDNIGHT, BUT
WILL BE SHORT-LIVED AND RELATIVELY LIGHT, WITH TOTALS NOT EXCEEDING
A TENTH OF AN INCH.
STRONG COLD AIR ADVECTION BEHIND THIS FRONT WILL ALLOW FOR GUSTY
WINDS THROUGHOUT MONDAY, WITH SOME SITES SEEING SHORT-LIVED GUSTS
INTO THE 40S. TEMPERATURES ARE EXPECTED TO BE MUCH MORE SEASONAL
THROUGHOUT THE WEEK WITH TUESDAY AND WEDNESDAY BEING OUR COLDEST,
WITH HIGHS TOPPING OUT IN THE MID 40S AND OVERNIGHT LOWS IN THE
MID 20S. A GRADUAL REBOUNDING OF TEMPS IS ON TAP FOR THE LAST HALF
OF THE WEEK, AS HIGHS RANGE IN THE MID 60S AND LOWS IN THE 40S.
NEW YEARS THROUGH THE WEEKEND..
REVELERS CAN EXPECT A COLD NIGHT FOR NEW YEARS EVE FESTIVITIES,
THOUGH THANKFULLY NOT AS COLD AS PREVIOUS NIGHTS. WE'LL SEE TEMPS
BEGIN TO REBOUND ON NEW YEARS DAY. CONTINUED SURFACE RIDGING WILL
MAINTAIN DRY CONDITIONS THROUGH THURSDAY, BUT A FEW SHOWERS MAY
RETURN LATE FRIDAY INTO EARLY SATURDAY AS A SOUTHERN STREAM SYSTEM
MOVES ACROSS THE DEEP SOUTH. THUNDER CANNOT BE RULED OUT WITH THAT
SYSTEM, BUT THE CURRENT TIMING DOES NOT APPEAR TO FAVOR ANY SEVERE
THREAT./OAJ
