DISCUSSION
(THIS AFTERNOON THROUGH NEXT FRIDAY)
ISSUED AT 1220 PM CDT SAT OCT 4 2025
OUTSIDE OF SOME CLOUDS OVER THE CENTER OF THE REGION, DRY AND
PLEASANT WEATHER IS EXPECTED TO CONTINUE TODAY AS HIGH PRESSURE
REMAINS ACROSS THE EASTERN CONUS. TEMPERATURES WILL CLIMB INTO THE
UPPER 80S THIS AFTERNOON WITH LOWS IN THE UPPER 60S. THIS
CONFIGURATION OF THE UPPER AND SURFACE PATTERNS WILL REMAIN
THROUGH TOMORROW WITH SIMILAR WEATHER TO TODAY.
GUIDANCE BRINGS A WEAK TROUGH UP FROM THE GULF MONDAY THE SURFACE
HIGH MOVES EAST. FORECAST UPPER AIR PROFILES DISPLAY DEEP MOISTURE
AND PWATS OF 1.8"-2.0", A SHARP CONTRAST TO OUR CURRENT DRY
AIRMASS. ALTHOUGH CAPE WILL BE SOMEWHAT LOW DUE TO THE MOIST-
ADIABATIC SHAPE OF THE ATMOSPHERIC TEMPERATURE PROFILE, ENOUGH
INSTABILITY WILL BE PRESENT MONDAY AFTERNOON TO BRING SCATTERED
SHOWERS AND STORMS TO THE REGION. A SIMILAR SETUP WILL EXIST ON
TUESDAY, BUT WITH MORE OF A FOCUS FOR PRECIPITATION DEVELOPMENT
ALONG A THETA E GRADIENT THROUGH THE CENTER OF THE REGION. THE
CURRENT FORECAST CALLS FOR UP TO 1.25" THROUGH WEDNESDAY, CENTERED
ALONG A THIS GRADIENT WHICH CURRENTLY SITS FROM FORREST CITY, AR
TO AROUND PARIS, TN. SOME AREAS COULD SEE LOCALLY HIGHER AMOUNTS,
ESPECIALLY WITH 90TH+ PERCENTILE PWATS AND SUPPORTIVE VERTICAL
TEMPERATURE PROFILES.
ON WEDNESDAY, THE UPPER RIDGE TO OUR EAST WILL BE SUPPRESSED,
RETROGRADING TO THE WESTERN CONUS BY THURSDAY. THIS WILL LEAVE
THE REGION IN A NORTHWESTERLY FLOW REGIME WITH SEVERAL, LOW-
AMPLITUDE SHORTWAVES AND A COLD FRONT PASSING OVER THE REGION.
BEHIND THE FRONT, GUIDANCE KEEPS DEW POINTS IN THE LOW TO MID 60S
THROUGH THE END OF THE WEEK WHERE THERE IS SUPPORT FOR A LOW
(20%-30%) CHANCE OF AFTERNOON SHOWERS WEDNESDAY AND THURSDAY. 850
MB MOISTURE WILL THEN GRADUALLY DECREASE WITH TIME INTO NEXT
WEEKEND, DECREASING OUR PRECIPITATION CHANCES. AT THE SAME TIME,
HIGH TEMPERATURES WILL DECREASE FROM THE UPPER 80S TO THE UPPER
70S AND LOW 80S WEDNESDAY THROUGH THE END OF THE FORECAST.
AVIATION
(18Z TAFS)
ISSUED AT 1220 PM CDT SAT OCT 4 2025
VFR. A MID-LEVEL CLOUD DECK IS STARTING TO SHOW SOME SIGNS OF
THINNING AND ERODING, BUT WILL LIKELY PERSIST FOR AT LEAST ANOTHER
COUPLE OF HOURS. HIGH PRESSURE CENTERED OVER THE APPALACHIANS
WILL KEEP EAST TO SOUTHEAST WIND OVER THE AIRSPACE. WIND SPEEDS
WILL INCREASE TO NEAR 10 KTS TOMORROW.
FIRE WEATHER
ISSUED AT 1220 PM CDT SAT OCT 4 2025
FIRE WEATHER CONCERNS WILL BE LOW THROUGH THE PERIOD AS 20 FT
