DISCUSSION

TODAY MAY NOT FEEL LIKE IT, BUT IS THE START OF A WARMING TREND
THROUGH THE PERIOD. TODAY'S BELOW NORMAL HIGHS IN THE LOW TO MID 70S
WILL CLIMB NEAR NORMAL TOMORROW, AND CONTINUE RISING INTO THE 90S BY
FRIDAY. DRY AND PLEASANT WEATHER WITH SOUTHERLY TO SOUTHEASTERLY
WINDS, BREEZY IN THE AFTERNOONS IN THE RGV, WILL PERSIST THROUGH THE
PERIOD.
THE WINDS ARE MUCH LIGHTER TODAY, BUT DRY AIR REMAINS. CRITICALLY TO
EXTREMELY DRY FUELS AND D2-D4 DROUGHT SUPPORT RAPID FIRE STARTS AND
COULD LEAD TO POTENTIAL WILDFIRES. OUTDOOR BURNING IS NOT
RECOMMENDED. MOISTURE BEGINS TO RETURN WEDNESDAY AND THURSDAY,
LOWERING FIRE WEATHER CONCERNS. SUBSIDENCE FROM MID LEVEL RIDGING
CENTERED OVER SW CONUS WILL RETURN DRY AIR TO THE REGION LATE THIS
WEEK. MINIMUM RELATIVE HUMIDITIES AS LOW AS THE TEENS ARE POSSIBLE
FRIDAY THROUGH SUNDAY IN THE RANCHLANDS AND RIO GRANDE PLAINS WEST
OF US 281.
AT LOCAL SOUTH TEXAS BEACHES, THERE IS A MODERATE RISK OF RIP
CURRENTS THROUGH TUESDAY EVENING. RIP CURRENTS ARE ESPECIALLY LIKELY
NEAR PIERS, JETTIES, AND OTHER STRUCTURES. PLEASE AVOID SWIMMING
NEAR THESE STRUCTURES.
