SHORT TERM
(TODAY)
ISSUED AT 1226 AM CDT THU OCT 9 2025
ANOTHER PREDOMINANTLY QUIET DAY IS FORECAST FOR THE AREA WITH
TEMPERATURES SIMILAR OR SLIGHTLY WARMER THAN WEDNESDAY. SFC HIGH
PRESSURE MOVES EAST TODAY ALLOWING FOR THE RETURN OF SOUTHERLY LOW
LEVEL FLOW THIS MORNING. THIS WILL HELP BRING MOISTURE NORTHWARD
EARLY IN THE DAY WITH WEAK INSTABILITY PERHAPS ALLOWING A FEW LIGHT
SHOWERS TO DEVELOP THIS MORNING IN PARTS OF NE OK AND SOUTHERN KS.
COVERAGE IS FORECAST TO REMAIN LOW, IF ANY, AND POPS REMAIN LESS
THAN 10%. OTHERWISE, PARTLY CLOUDY SKIES BECOME MOSTLY SUNNY WITH
HIGH TEMPS IN THE UPPER 70S OR LOWER 80S... MAKING FOR ANOTHER
PLEASANT DAY.
LONG TERM
(TONIGHT THROUGH WEDNESDAY)
ISSUED AT 1226 AM CDT THU OCT 9 2025
UPPER LEVEL RIDGING EXPANDS INTO THE SOUTHERN PLAINS TONIGHT WITH
NORTHWESTERLY FLOW ALOFT OCCURRING OVER MUCH OF THE CENTRAL
STATES. A WEAK WAVE EMBEDDED IN THE FLOW WILL PASS NEAR THE AREA
LATE TONIGHT INTO FRIDAY, PERHAPS ALLOWING FOR A FEW ADDITIONAL
SHOWERS IN PARTS OF NE OK AND NW AR. MEANINGFUL RAINFALL IS NOT
EXPECTED WITH THIS FEATURE EITHER. RIDGING MOVES MORE DIRECTLY
OVERHEAD GOING INTO THIS WEEKEND MAINTAINING DRY CONDITIONS. THIS
WILL ALSO ALLOW FOR INCREASING TEMPERATURES AS SOUTHERLY FLOW
INTENSIFIES SATURDAY AND SUNDAY. HIGH TEMPERATURES WILL AGAIN BE
10-15 DEGREES ABOVE AVERAGE DURING THIS TIME, GENERALLY IN THE 80S
OR NEAR 90 DEGREES. ADDITIONALLY, THE PRESSURE GRADIENT TIGHTENS
ON SUNDAY AS A SFC LOW MOVES INTO THE C PLAINS. THIS WILL
ENCOURAGE A PERIOD OF STRONGER WINDS SUNDAY AFTERNOON, ESPECIALLY
ALONG AND NORTH OF I-44... GENERALLY 10-20 MPH GUSTING TO 30 MPH.
GIVEN THE VERY WARM TEMPERATURES, LACK OF RECENT WETTING RAINS,
AND MIN RHS IN THE 20- 40% RANGE, AT LEAST LIMITED FIRE WEATHER
CONCERNS ARE EXPECTED WEST OF HIGHWAY 75 IN NE OK.
AMPLIFIED LONGWAVE TROUGHING DEVELOPS OVER THE WESTERN HALF OF THE
COUNTRY EARLY TO MID NEXT WEEK. THIS WILL SUPPRESS THE
AFOREMENTIONED RIDGING AND PROVIDE AN ELONGATED PLUME OF SW FLOW
ACROSS MUCH OF THE CENTRAL CONUS, HELPING TO TRANSPORT TROPICAL
MOISTURE FROM NW MEXICO/ E PACIFIC. A SHORTWAVE EJECTS INTO THE
PLAINS SUNDAY INTO MONDAY SENDING A FRONTAL BOUNDARY INTO THE
REGION. MODELS STILL DIFFER IN TERMS OF BOUNDARY PLACEMENT AND
QPF, BUT LOCATIONS ALONG AND NORTH OF I-44 APPEAR MOST FAVORABLE
TO RECEIVE SOME RAIN ON MONDAY. GIVEN ONGOING DISCREPANCIES, POPS
REMAIN ON THE LOWER END... GENERALLY 15-25%. RIDGING ATTEMPTS TO
RE-ESTABLISH ITSELF GOING INTO MID WEEK WITH A DRY AND WARM
FORECAST CONTINUING FOR NOW. HIGH TEMPERATURES MAY DECREASE
SLIGHTLY MONDAY AND TUESDAY, BUT STILL REMAIN ABOVE AVERAGE FOR
THIS TIME OF YEAR IN THE 80S THROUGH THE END OF THE PERIOD.
