DISCUSSION

HIGH PRESSURE DOMINATES DEEP SOUTH TEXAS INTO NEXT WEEK, WITH
TEMPERATURES ONCE AGAIN WARMING ABOVE NORMAL AND NO CHANCE OF
RAIN. BREEZY SOUTHEASTERLY WINDS EACH AFTERNOON MAY HELP MAINTAIN
RELATIVE HUMIDITY VALUES ABOVE ANY FIRE WEATHER CRITERIA ALONG AND
EAST OF US281/I69C. RELATIVE HUMIDITY VALUES TO THE WEST ACROSS
THE BRUSH COUNTRY WILL DROP BELOW 20-30 PERCENT EACH AFTERNOON,
BUT DO SO WITHOUT THE BREEZE, UNTIL THE EVENING WHEN MOISTURE IS
RECOVERING, POTENTIALLY LIMITING ADDITIONAL FIRE WEATHER CONCERNS
AT THIS TIME.
THE ENTIRE REGION REMAINS PRIMED FOR WILDFIRES AND BURN BANS ARE
IN EFFECT ACROSS ALL OF DEEP SOUTH TEXAS, EXCEPT KENEDY COUNTY.
FOR WHAT IT'S WORTH, CPC IS LEANING TOWARD ABOVE NORMAL RAINFALL
OCCURRING DURING THE FINAL WEEK OF MARCH AT 40-50 PERCENT
PROBABILITY.
