FIRE WEATHER PLANNING FORECAST
NATIONAL WEATHER SERVICE LAKE CHARLES LA
308 PM GMT TUE OCT 20 2026
DISCUSSION
AN OMEGA BLOCK PATTERN WITH A BUILDING RIDGE OVER THE SOUTH-CENTRAL
US WILL KEEP DRY CONDITIONS IN PLACE OVER THE CWA THROUGH THE
WEEKEND AND INTO NEXT WEEK. AFTERNOON HIGHS WILL BE ON A SLIGHT
WARMING TREND, WITH NO REAL INCREASE IN MOISTURE EXPECTED, WHICH
WILL ALLOW RH TO FALL TO THE 25 TO 35 PERCENT RANGE EACH AFTERNOON.
ALTHOUGH WINDS WILL REMAIN LIGHT THROUGH THE FORECAST PERIOD, OUT OF
THE EAST AT AROUND 5-10 MPH, FIRE DANGER IS LIKELY TO BE ELEVATED
EACH AFTERNOON WITH THE COMBINATION OF THE DRY AIRMASS AND VERY DRY
FUELS DUE TO ONGOING DROUGHT.
