SURFACE WINDS HAVE BECOME NORTHERLY ACROSS ALL OF NORTH TEXAS AS
OF 09Z. HOWEVER...LOOKING AT THE DEW POINTS...THE ACTUAL COLD
FRONT EXTENDS SOUTHEAST OF A GAINESVILLE TO BROWNWOOD LINE.
WIDESPREAD FOG CONTINUES ALONG AND SOUTHEAST OF THE FRONT.
VISIBILITIES WILL BE MOSTLY IN THE RANGE OF 1 TO 3 MILES...BUT SOME
SPOTS WILL BE LOWER...WITH SOME PATCHY DENSE FOG POSSIBLE. THE FOG
WILL DISPERSE LATER THIS MORNING. HAVE KEPT SOME LOW POPS ACROSS THE
SOUTHEASTERN THIRD...WHERE LIGHT RAIN/DRIZZLE MAY PRODUCE A FEW ONE
HUNDREDTHS OF AN INCH.
NOT MUCH OF A CHANGE IS EXPECTED IN THE OVERALL UPPER LEVEL PATTERN
THIS WEEK. THIS WILL RESULT IN A SERIES OF FRONTS MOVING THROUGH THE
