WINDS ACROSS THE AREA WILL REMAIN OUT OF THE WEST-SOUTHWEST THROUGH
THE EARLY AFTERNOON, BEFORE A COLD FRONT MOVES IN FROM THE NORTH.
CURRENT DATA SHOWS THE FRONT ARRIVING IN SOUTHERN EL PASO COUNTY
BETWEEN 3PM AND 5PM THIS AFTERNOON, WITH WINDS SHIFTING OUT OF THE
NORTHWEST, AND THEN THE NORTH.
OVER THE NEXT FEW HOURS, UNTIL THE FRONT PASSES, THERE WILL BE A
CHANCE FOR A FEW HIGH-BASED SHOWERS IN THE GENERAL AREA. NO
PRECIPITATION IS EXPECTED TO HIT THE GROUND, BUT VIRGA AND OUTFLOW
WINDS WILL BE POSSIBLE. CURRENT CONFIDENCE PUTS CHANCES FOR
OUTFLOW NEAR THE FIRE AROUND 50 PERCENT.
IN GENERAL, WINDS WILL GUST 30-35 MPH THROUGH ABOUT 3PM, WEAKENING
SLIGHTLY AS THE FRONT MOVES THROUGH. ALONG AND BEHIND THE FRONT,
GUSTS WILL BE MORE IN THE 25-30 MPH RANGE, THOUGH ANY VIRGA COULD
GIVE BRIEF GUSTS TO 45 MPH.
ONCE THE FRONT IS THROUGH, WINDS WILL WEAKEN THIS EVENING INTO
TONIGHT, TURNING NORTHEASTERLY BEFORE BECOMING LIGHT AND VARIABLE
CLOSER TO MIDNIGHT. CLOUDS OVERNIGHT WILL MOSTLY CLEAR, WITH RH
RECOVERING TO 40-45 PERCENT. LOW TEMPS TONIGHT WILL BE IN THE MID-
30S.
