DISCUSSION
ISSUED AT 1208 PM CDT SUN MAR 29 2026
HIGH PRESSURE WILL BUILD ACROSS THE MID-ATLANTIC THROUGH THE WEEK
MAINTAINING ONSHORE FLOW. A WEAK TROUGH OVER MEXICO WILL MAINTAIN
A LOW CHANCE (10-30%) OF POPS TODAY IN THE LOW TO MID-VALLEY. HAVE
SEEN A FEW BRIEF LIGHT SHOWERS POP UP HERE AND THERE THIS
MORNING, AND WILL LIKELY REMAIN THE CASE THROUGH THE AFTERNOON.
DRY CONDITIONS WILL PREVAIL THROUGH MUCH OF THE WEEK, THOUGH A
WEAK DISTURBANCE OVERHEAD TUESDAY COULD BRING SOME SHOWERS TO THE
COAST. AS WE HEAD INTO THIS WEEKEND, ANOTHER FRONT MAY MOVE
THROUGH DEEP SOUTH TEXAS, AGAIN BRINGING LOW RAIN CHANCES ALONG
THE COAST.
TEMPERATURES WILL REMAIN ABOVE NORMAL THROUGH THE THE WEEK, BUT A
COLD FRONT THIS WEEKEND COULD DROP TEMPERATURES NEAR OR BELOW
NORMAL BY EARLY NEXT WEEK.
WHILE WINDS AND HUMIDITY LEVELS FALL SHY OF ANY RED FLAG/FIRE
DANGER STATEMENTS, WILL BE MONITORING THE SITUATION CLOSELY FOR
POTENTIAL ISSUANCE. ONGOING DROUGHT WITH CRITICAL TO EXTREMELY DRY
FUELS COULD LEAD TO RAPID WILDFIRE GROWTH IF IGNITED. BURN BANS
ARE IN EFFECT FOR CAMERON, HIDALGO, WILLACY, BROOKS, JIM HOGG,
ZAPATA, AND STARR COUNTIES.
