AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
241 PM CST FRI FEB 21 2025
..NEW SHORT TERM, LONG TERM, MARINE
KEY MESSAGES
- STEADY WARM UP THROUGH THE WEEKEND.
- AN UPPER LEVEL DISTURBANCE AND A SURFACE LOW WILL COMBINE TO
PRODUCE WIDESPREAD SHOWER ACTIVITY WITH A FEW THUNDERSTORMS THAT
WILL BRING A COLD SOAKING RAIN FROM LATE SATURDAY AFTERNOON
INTO SUNDAY.
- CALM WEATHER FOR THE EXTENDED FORECAST.
SHORT TERM
(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 238 PM CST FRI FEB 21 2025
TONIGHT WE WILL SEE OUR TEMPERATURES BEGIN TO REBOUND TO MORE
TYPICAL VALUES IN THE LOW TO MID-30S AS THE ARCTIC AIR MASS BEGINS
TO WASH AWAY. OVERNIGHT LOWS MAY GET BELOW FREEZING FOR AREAS
NORTH OF I-10, WHILE ELSEWHERE WILL STAY ABOVE FREEZING. THE SLOW
BUT STEADY INCREASE IN OUR TEMPERATURES WILL CONTINUE INTO THE
WEEKEND WITH HIGHS IN THE 50S.
ALOFT, AN UPPER-LEVEL DISTURBANCE WILL BEGIN TO DROP SOUTH FROM
THE ROCKIES WHILE A SURFACE LOW DEVELOPS IN THE GULF OF AMERICA.
THESE FEATURES WILL LEAD TO WIDESPREAD RAIN SATURDAY NIGHT AND
SUNDAY. SEVERE WEATHER IS NOT EXPECTED WITH THIS EVENT AS THE WARM
SECTOR WILL REMAIN WELL OFFSHORE. THIS WILL LEAD TO SURFACE-BASED
CAPE NEAR ZERO, WITH EVEN THE 90TH PERCENTILE SHOWING VALUES ONLY
AROUND 60 J/KG. ELEVATED CAPE VALUES ARE MORE FAVORABLE FOR
THUNDERSTORMS, AND WE COULD SEE ONE OR TWO STRONGER STORMS, BUT
OVERALL THE THREAT REMAINS LOW. FARTHER FROM THE COAST, THE WARM
CLOUD LAYER WILL DECREASE WITH LIGHTER RAIN AND NO THUNDER. HOW
DEEP THE CLOUD LAYER IS WILL DEPEND ON THE LOCATION OF THE SURFACE
LOW, SO WHERE THE CUTOFF FOR THUNDER WILL BE IS, (PARDON THE
PUN,) UP IN THE AIR.
RAINFALL WILL BE WIDESPREAD, BUT WITH LOW CAPE VALUES AND A LOW
FREEZING LEVEL, RAIN RATES ARE NOT EXPECTED TO BE A CONCERN.
INSTEAD, EXPECT A STEADY SOAKING RAIN EVENT WITH TOTAL AMOUNTS
BETWEEN 1 AND 2 INCHES.
LONG TERM
(MONDAY THROUGH NEXT THURSDAY)
ISSUED AT 238 PM CST FRI FEB 21 2025
GOING INTO NEXT WEEK, OUR WEATHER WILL BE CALM AS HIGH PRESSURE
SETS UP OVERHEAD. TEMPERATURES WILL STEADILY RISE. ON WEDNESDAY, A
WEAK COLD FRONT WILL PUSH ACROSS THE REGION. THE MAIN IMPACT FROM
THIS FRONT WILL BE A DROP IN TEMPERATURES BY 5 TO 10 DEGREES,
DOWN INTO THE HIGH 60S, WHILE DEW POINTS WILL FALL INTO THE 40S.
RAIN CHANCES WILL BE LOW THROUGHOUT THE EXTENDED FORECAST.
AVIATION
