NEAR TERM
(TODAY)
ISSUED AT 357 AM CDT THU OCT 22 2026
NO MAJOR ADJUSTMENTS WERE MADE TO THE PREVIOUS FORECAST OUTSIDE OF
LOWERING DEW POINTS ONCE AGAIN THIS AFTERNOON- ALLOWING RH VALUES
TO DROP INTO THE 25-30% RANGE. LIGHT, VARIABLE WINDS WILL
ALLEVIATE ANY POTENTIAL FIRE WEATHER CONCERNS. OTHERWISE, PATCHY
FOG HAS FORMED IN ISOLATED AREAS ACROSS THE TN VALLEY AND SHOULD
DISSIPATE SHORTLY AFTER SUNRISE. USE CAUTION ON YOUR MORNING
COMMUTE!
PREVIOUS DISCUSSION:
TONIGHT'S FORECAST FEELS LIKE A RINSE AND REPEAT OF LAST NIGHT.
SATELLITE IMAGERY SHOWS A CLOUD DECK SLIDING SSE, JUST OFF TO OUR
WEST. MOSTLY CLEAR SKIES WILL PREVAIL TONIGHT, AND WITH LIGHT
WINDS IN PLACE, PATCHY FOG CAN FORM IN THE VALLEYS AND NEAR BODIES
OF WATER. LOWS WILL FALL INTO THE 40S SO BE SURE TO GRAB THAT
JACKET AGAIN FOR YOUR MORNING COMMUTE OR BUS STOP.
THURSDAY WILL ALSO FEEL LIKE DEJA VU. THE VAST RIDGE OF HIGH
PRESSURE ESTABLISHED THROUGHOUT THE PLAINS WILL ONLY LEAN TO THE
EAST A LITTLE BIT. WE WILL REMAIN UNDER THE INFLUENCE OF HIGH
PRESSURE, WHERE DRY CONDITIONS WILL PERSIST AND TEMPS WILL BE A
DEGREE OR TWO HIGHER THAN YESTERDAY. LOOK FOR DAYTIME HIGHS TO
REACH THE MID TO UPPER 70S.
SHORT TERM
(THURSDAY NIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 955 PM CDT WED OCT 21 2026
AFTER REACHING THE MID TO UPPER 70S ON THURSDAY, UNDER MOSTLY
CLEAR TO PARTLY CLOUDY SKIES, TEMPS WILL FALL INTO THE 40S ONCE
AGAIN. SO KEEP THAT LIGHT JACKET BY THE DOOR TO GRAB IT FOR YOUR
MORNING COMMUTE OR BUS STOP. THE AMPLIFIED RIDGE WITH AN AXIS
THROUGH THE PLAINS AND INTO THE MIDWEST ON FRIDAY WILL ONLY SLIDE
SLIGHTLY EASTWARD. THIS WILL NUDGE THE SFC HIGH DRAPED ACROSS THE
EASTERN HALF OF THE CONUS AS WELL, VEERING OUR SFC WINDS TO
BECOME MORE SOUTHEASTERLY. HIGHS ONCE AGAIN WILL BE IN THE 70S
WITH LOWER 70S IN THE ELEVATED TERRAIN AND THE MID TO UPPER 70S
ELSEWHERE. OVERNIGHT LOWS ON FRIDAY WILL REMAIN GENERALLY IN THE
40S.
LONG TERM
(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 955 PM CDT WED OCT 21 2026
ON SATURDAY AND SUNDAY, A NARROW BUT AMPLIFIED 5H RIDGE AXIS OVER THE
LOWER MO VALLEY SOUTH INTO THE WESTERN GULF OF AMERICA WILL BE IN
PLACE, PROVIDING NORTHERLY FLOW ALOFT OVER THE TN VALLEY. A SPRAWLING
SURFACE AND 8H RIDGE WILL BE IN PLACE FROM NEW ENGLAND THROUGH THE
LOWER MS VALLEY. THIS WILL KEEP DRY AND SEASONABLE WEATHER IN PLAY
THROUGH EARLY NEXT WEEK. THE RIDGE WILL BREAK DOWN MONDAY AND
TUESDAY AS THE SOUTHWEST U.S. EJECTS INTO THE PLAINS AND OH VALLEY.
THE SOUTHERN TAIL OF THIS WAVE WILL MOVE THROUGH TUESDAY INTO
WEDNESDAY, BUT THE AIRMASS WILL TOO DRY TO SUPPORT PRECIPITATION.
THE SURFACE RIDGE WILL REMAIN IN PLACE, BUT PRESSURES WILL BE FALLING
AS IT WEAKENS. TEMPERATURES IN UPPER 60S TO LOWER 70S ON MONDAY
UNDER THE INFLUENCE OF THE WEDGING RIDGE WILL WARM INTO THE LOWER TO
MIDDLE 70S TUESDAY AND WEDNESDAY. LOWS WILL BE IN THE LOWER TO MIDDLE
40S OVER THE WEEKEND INTO MONDAY MORNING, WARMING INTO THE MIDDLE
40S TO AROUND 50 BY WEDNESDAY AND THURSDAY MORNINGS.
