ADVISORY CRITERIA, SLIGHTLY ELEVATED WINDS AND GUSTS PERSIST
ACROSS THE CWA. THIS WILL CONTINUE TO RELAX AS THE HIGH SINKS
FURTHER SOUTH.
TEMPERATURES WILL BE DEPENDENT ON THE WINDS AND CLOUD COVER. CLOUD
COVER IS STILL ERODING, WHICH WILL ALLOW FOR FURTHER COOLING, AND
WE COULD SEE TEMPERATURES BOTTOMING OUT IN THE UPPER 20S TO 30S.
WINDS ARE EXPECTED TO BE IN THE 5 TO 15 MPH RANGE WHICH WILL YIELD
APPARENT TEMPERATURES RANGING FROM THE LOWER TO UPPER 20S. THE
RANGES ARE JUST ABOVE CRITERIA FOR A COLD WEATHER ADVISORY;
THEREFORE, THE ADVISORY WILL NOT BE ISSUED. TUESDAY NIGHT INTO
WEDNESDAY MORNING WILL SEE THE COLDEST TEMPERATURES OF THIS BRIEF
COLD SNAP, WITH LOWS BOTTOMING OUT IN THE UPPER 20S TO LOWER 30S.
FORTUNATELY, WIND SPEEDS WILL DECREASE CONSIDERABLY AS SURFACE
HIGH PRESSURE MOVES INTO THE SOUTHERN PLAINS, RESULTING IN

OR BELOW FREEZING, AND FROST WILL BE POSSIBLE.
HIGH TEMPERATURES TUESDAY WILL REACH THE 50S UNDER SUNNY SKIES. BY
WEDNESDAY, THE SURFACE HIGH WILL SETTLE ALONG THE GULF COAST
BEFORE SHIFTING SOUTH OVER THE GULF WATERS. WINDS WILL BECOME
