KEY MESSAGES
- HOT AND DRY WEATHER WILL CONTINUE UNTIL SATURDAY, WITH DAYTIME
HIGHS TOPPING OUT IN THE UPPER 80S TO LOWER 90S. TEMPERATURES
LOOKS TO COOL DOWN BY THE MIDDLE OF NEXT WEEK.
- A SLOW MOVING UPPER LEVEL LOW WILL BRING DAILY CHANCES (20 TO 40
PERCENT) FOR SHOWERS AND THUNDERSTORMS EARLY NEXT WEEK. THE
BEST CHANCE (50-70%) FOR SHOWERS AND THUNDERSTORMS COMES SUNDAY
INTO MONDAY. PRECIPITATION LOOKS TO BE GENERALLY LIGHT.
DISCUSSION
ISSUED AT 217 AM CDT THU SEP 18 2025
ANOTHER DAY, ANOTHER ROUND OF HOT AND DRY WEATHER, BUT THERE'S A
SMALL BIT OF GOOD NEWS: LIGHT WINDS SHOULD HELP KEEP FIRE DANGER IN
CHECK WITH THE DROUGHT IN PLACE. THIS PATTERN IS EXPECTED TO CHANGE
AS A SLOW WEATHER SYSTEM MOVES INTO THE REGION THIS AFTERNOON,
BRINGING A DAILY CHANCE OF SHOWERS AND THUNDERSTORMS THAT WILL LAST
INTO NEXT WEEK. A DROUGHT-BUSTING RAIN IS NOT EXPECTED, THOUGH.
THERE IS A 30-50% CHANCE OF GETTING MORE THAN AN INCH OF RAIN BY
NEXT WEDNESDAY MORNING FROM THE LREF. SUNDAY INTO MONDAY LOOKS TO BE
THE BEST PROBABILITY OF SHOWERS AND THUNDERSTORMS, WITH WITH POPS OF
50-70%.
A MORE PROGRESSIVE, POTENTIALLY WETTER, PATTERN LOOKS TO BE SETTING
UP, AS THERE IS A SIGNAL FOR ANOTHER LOW PRESSURE SYSTEM TO MOVE
THROUGH THE FORECAST AREA BY MID WEEK. THIS WILL BRING ADDITIONAL
RAIN CHANCES, MAYBE EVEN A STRONG STORM OR TWO (??). THIS SYSTEM
LOOKS TO BE MORE POTENT THAN THIS WEEKEND'S SYSTEM.
HIGHS WILL BE IN THE UPPER 80S TO LOW 90S THROUGH SATURDAY, BEFORE A
WELCOME COOL DOWN INTO THE LOW TO UPPER 80S ARRIVES FOR THE START OF
THE NEW WEEK. OVERNIGHT LOWS WILL STAY IN THE 60S THROUGH MONDAY
NIGHT. THEN, OVERNIGHT LOWS IN THE MID TO UPPER 50S TAKE OVER
THROUGH THE EXTENDED. IT LOOKS LIKE THE TEMPERATURES WILL DROP
CLOSER TO NORMAL (MID 70S-ISH), BUT STAYING SLIGHTLY ABOVE NORMAL,
LATE IN THE WEEK.
