LOCALIZED SPOTS. MOSTLY CLOUDY, EVEN DRIZZLY CONDITIONS WILL KEEP
TEMPERATURES DOWN AND RELATIVE HUMIDITY HIGH TODAY, WHILE EASTERLY
WINDS GENERALLY INCREASE TOWARDS 10 MPH. OVERNIGHT, A COMPLEX OF
THUNDERSTORMS MAY MOVE IN FROM THE WEST AHEAD OF AND ALONG A
STRONG ARCTIC FRONT. THE BEST POTENTIAL FOR STORMS WILL BE TO THE
SOUTHWEST OF THE HOUSTON METRO, TOWARDS THE MATAGORDA BAY AREA.
THE FRONT WILL SWEEP THROUGH, AND A COLD, ARCTIC AIRMASS WILL
BEGIN SPILLING INTO THE AREA SATURDAY AND PERSIST INTO EARLY NEXT
WEEK. WHILE THIS WILL FIRST BE ACCOMPANIED BY RAIN SHOWERS, THERE
WILL BE A TRANSITION TO FREEZING RAIN AND PERHAPS EVEN SOME SLEET
BEFORE PRECIPITATION COMES TO AN END ON SUNDAY. VERY COLD
CONDITIONS WILL CONTINUE INTO THE NEW WEEK, WITH TEMPERATURES
STRUGGLING TO EVEN REACH THE FREEZING MARK IN MANY LOCATIONS UNTIL
