LOOKS LIKE THE COLD AIR IS HERE TO STAY TODAY AS CLOUD COVER HAS HELD
ON FOR A FEW MORE HOURS THAN ORIGINALLY FIRST THOUGHT. AS A
RESULT...MANY LOCATIONS ARE STILL JUST IN THE TEENS AND 20S THIS
HOUR. LOWERED HIGH TEMPERATURES A GOOD 2-5 DEGREES AREA WIDE
ESPECIALLY WHERE CLOUD COVER REMAINS. NO ADDITIONAL CHANGES WERE MADE
TO THE FORECAST OTHER THAN TO INCREASE SKY COVER.
