ISSUED AT 131 PM CDT THU MAY 29 2025
THROUGH TOMORROW:
IN THE WAKE OF THE LATEST DISTURBANCE - A SOUTHERN STREAM SYSTEM
MOVING ALONG THE GULF COAST - RISING MID-LEVEL HEIGHTS INDICATE A
MORE SUPPRESSED ENVIRONMENT ACROSS OUR FORECAST AREA THIS AFTERNOON.
A FEW SHOWERS OR STORMS CAN'T BE RULED OUT WITH DAYTIME HEATING
STILL LEADING TO 1500-2500 J/KG OF SBCAPE. ACTIVITY SHOULD DECREASE
AFTER DARK, BUT THEN ONE FINAL DISTURBANCE IN THIS STRING OF ACTIVE
WEATHER WILL PIVOT EAST ACROSS THE MIDWEST AND MID-SOUTH REGIONS
HEADING INTO TOMORROW MORNING. THE WAVE WILL BRING A CHANCE FOR
ADDITIONAL SHOWERS THROUGH THE MORNING, AND THEN POSSIBLE
THUNDERSTORMS AS THE WAVE CROSSES SOUTHERN MISSISSIPPI TOMORROW
AFTERNOON. THIS SYSTEM'S COLD FRONT WILL CLEAR OUR AREA BY TOMORROW
NIGHT.
SATURDAY THROUGH THURSDAY:
HIGH PRESSURE AND DRIER AIR WILL FILTER INTO THE REGION FOR THE
WEEKEND (DEW POINTS INTO THE 50S AND 60S). THE PATTERN IS A LITTLE
TRICKY WITH STRONG RIDGING OVER THE NORTHERN ROCKIES, A CUTOFF LOW
NEAR THE BAJA PENINSULA, AND TROUGHING OVER THE US EAST COAST. A
FAST-MOVING SHORTWAVE COMING AROUND THE WEST SIDE OF THE TROUGH
COULD BRING A CHANCE FOR RAIN SUNDAY OR MONDAY, BUT CONFIDENCE FOR
MOST OF OUR AREA IS TOO LOW TO INCLUDE IN THE FORECAST AT THIS TIME.
HIGH PRESSURE OFF THE EAST COAST WILL BRING THE RETURN OF WARM,
HUMID AIR FROM THE SOUTH. RIDGING PASSING OVERHEAD WILL SUPPORT
ABOVE NORMAL TEMPERATURES AS WELL. THEREFORE THE SUMMERY COMBINATION
OF HEAT AND HUMIDITY WILL RETURN TO THE REGION BY THE BACK HALF OF
THE WEEK. AND ACCORDINGLY, SOME STORMINESS COULD BE POSSIBLE
DEPENDING ON HOW THE PATTERN SETS UP. /NF/
