DISCUSSION
ISSUED AT 214 AM CDT MON OCT 27 2025
TODAY THROUGH SUNDAY...CONTINUING TO MONITOR FOG AND LOW CEILINGS
ACROSS MUCH OF THE AREA THIS MORNING. WHILE SOME OF THIS IS
DENSE, BASED ON THE MAJORITY OF CURRENT OBSERVATIONS AND TRAFFIC
CAMERAS ACROSS THE AREA, IT'S NOT WIDESPREAD. I'LL CONTINUE TO
ADVERTISE A "LIMITED" THREAT FOR PATCHY DENSE FOG IN THE HWO. IF
DENSE FOG BECOMES MORE PREVALENT OVER THE NEXT FEW HOURS, A "DENSE
FOG ADVISORY" MAY BE ISSUED FOR PORTIONS OF THE AREA.
A LOW PRESSURE SYSTEM WILL CONTINUE TO SLOWLY MOVE EAST THROUGH THE
REGION TODAY. THIS WILL CONTINUE TO RESULT IN A GOOD BIT OF CLOUD
COVER REMAINING ACROSS THE FORECAST AREA TODAY, ALONG WITH SOME
LINGERING LIGHT SHOWERS ACROSS MAINLY THE GOLDEN TRIANGLE AREA THIS
AFTERNOON. AS THE LOW PASSES, WINDS WILL STEADILY BECOME MORE
NORTHERLY IN ITS WAKE. THIS'LL BRING SOME SLIGHTLY COOLER DRIER
INTO THE REGION OVERNIGHT. OTHERWISE, LOOK FOR HIGHS THIS AFTERNOON
TO RANGE FROM THE MIDDLE 60S NORTH TO UPPER 70S SOUTH, WITH LOWS
TONIGHT FALLING INTO THE LOW AND MIDDLE 50S.
ANOTHER PIECE OF ENERGY WILL BREAK-OFF OF A CLOSED LOW PRESSURE
SYSTEM MEANDERING ABOUT ALBERTA AND SASKATCHEWAN CANADA AND DEEPEN
AS IT DIVES SOUTH SOUTHEAST ACROSS THE MIDWEST AND INTO THE
SOUTHEAST UNITED STATES TUESDAY THROUGH THURSDAY. THIS CLOSED LOW
WILL DRAG A COLD FRONT EAST INTO AND THROUGH THE FORECAST AREA LATE
TUESDAY NIGHT INTO WEDNESDAY MORNING. WITH IT, ANOTHER GOOD
COVERAGE OF BOTH CLOUDS AND RAIN CHANCES ACROSS THE CWA OVERNIGHT
TUESDAY THROUGH AT LEAST WEDNESDAY NIGHT.
THE BIGGER STORY WILL BE THE AIRMASS CHANGE THAT OCCUR ACROSS THE
REGION IN THE WAKE OF THIS COLD FRONT WEDNESDAY THROUGH FRIDAY AS
THE COOLEST AIR OF THIS EARLY AUTUMN SEASON ADVECTS INTO THE REGION.
DURING THIS TIME, BUT MAINLY WEDNESDAY AND THURSDAY, HIGH
TEMPERATURES WILL RANGE FROM THE MIDDLE 50S TO MIDDLE 60S, BUT WILL
REBOUND A BIT ON FRIDAY INTO THE 60S TO AROUND 70. OVERNIGHT LOWS
THOUGH WILL REALLY BE WHERE THIS COOL DOWN IS FELT, AS LOWS
WEDNESDAY NIGHT FALL INTO THE 40S, BUT INTO THE UPPER 30S AND LOWER
40S BOTH THURSDAY NIGHT AND FRIDAY NIGHT. PLEASE CONTINUE TO
MONITOR LATER FORECASTS DURING THIS TIMEFRAME, AS SOME LOCATIONS
COULD POTENTIALLY SEE SOME LIGHT PATCHY FROST LATE IN THE WEEK.
TEMPERATURES WILL CONTINUE TO REBOUND OVER THE UPCOMING WEEKEND WITH
HIGH PRESSURE SLIDING EAST OF THE FORECAST AREA. ANOTHER COLD FRONT
WILL SWING THROUGH THE REGION LATE IN THE WEEKEND. THIS WILL AGAIN
BRING SOME CLOUD COVER AND SMALL RAIN CHANCES TO THE FORECAST AREA
LATE SATURDAY NIGHT THROUGH SUNDAY. /19/
