SHORT TERM /THROUGH MONDAY/
ISSUED AT 126 PM CST SUN FEB 15 2026
UPPER LEVEL ANALYSIS AND WATER VAPOR SHOW A CLOSED LOW OVER THE
SOUTHEAST U.S. WHICH AIDED IN BRINGING US SOME MUCH NEEDED
RAINFALL TO THE FORECAST AREA, BUT ALSO BROUGHT SEVERE WEATHER
TO THE LOWER MISSISSIPPI VALLEY YESTERDAY. A RIDGE AXIS WAS
BUILDING INTO THE AREA BEHIND THE UPPER WAVE FROM THE PLAINS
WITH ANOTHER CLOSED LOW OFF THE PACIFIC COAST. THE SURFACE LOW
WAS OVER NORTHWEST ALABAMA EARLY THIS AFTERNOON WITH SOME GUSTY
NORTHERLY WINDS BEHIND THE LOW OVER THE MISSOURI OZARKS AND
SOUTHEAST KANSAS. THE EXTENSIVE LOW CLOUD COVER WHICH WAS OVER
THE AREA EARLIER THIS MORNING QUICKLY DISSIPATED BY LATE
MORNING. TEMPERATURES AT NOON WERE RANGING FROM THE MID 40S TO
LOW 50S WITH DEWPOINTS IN THE LOW TO MID 40S.
TONIGHT: SOME RADIATIONAL FOG WILL BE POSSIBLE TONIGHT
ESPECIALLY OVER THE SOUTHEAST 1/2 OF THE CWA WHERE LIGHT AND
VARIABLE WINDS WILL RESIDE THE LONGEST INTO THE OVERNIGHT. WE
SHOULD START TO SEE SOME LIGHT FOG DEVELOPING AROUND MIDNIGHT AS
WE APPROACH THE CROSSOVER TEMPERATURES IN THE LOW TO MID 40S
WITH A CLEAR SKY AND LIGHT WIND. HREF PROBABILITIES OF >50% FOR
DENSE FOG FORMATION OVER THE SOUTHEAST 1/2 OF THE CWA AFTER 06Z
AND LINGER UNTIL AROUND 12Z-13Z. NOT PLANNING ON AN ADVISORY
JUST YET SINCE IT ISN'T A SLAM DUNK, BUT ADDED THIS POTENTIAL IN
THE FORECAST. LESS CHANCE FOR FOG IN THE NORTHWEST 1/2 OF THE
CWA DUE TO SURFACE WINDS INCREASING EARLIER IN THE OVERNIGHT
HOURS AS THE PRESSURE GRADIENT INCREASES WITH AN APPROACHING
LOW PRESSURE SYSTEM. LOWS TONIGHT ARE EXPECTED IN THE MID 30S IN
THE SOUTHEAST AND THE LOW 40S IN THE WEST.
MONDAY: UPPER LEVEL RIDGE BEGINS TO PUSH INTO THE AREA FROM THE
WEST ALONG WITH LOW LEVEL WARM ADVECTION SETTING UP. SURFACE
WINDS MAY GUST UP TO 30 MPH OVER THE WESTERN CWA. FOG SHOULD
CLEAR OUT BY LATE MORNING WITH AFTERNOON SUNSHINE WARMING
TEMPERATURES INTO THE MID 60S TO AROUND 70 DURING THE AFTERNOON.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
ISSUED AT 126 PM CST SUN FEB 15 2026
WINDY CONDITIONS TUESDAY: AS THE STORM SYSTEM PUSHES INTO THE
WESTERN U.S. WITH ASSOCIATED STRONG UPPER LEVEL JET(150-160KTS),
LOW PRESSURE WILL STRENGTHEN OVER THE NORTHERN AND CENTRAL
PLAINS. THE TIGHT PRESSURE GRADIENT WILL DEVELOP STRONG WINDS
IN THE LOWER ATMOSPHERE. MIXING UP TO AROUND 900MB SHOWS A
POTENTIAL MOMENTUM TRANSFER OF 30 TO 40 KTS. WE MAY SEE SOME
WIND GUSTS IN EXCESS OF 35 MPH DURING THE DAY WEST OF
SPRINGFIELD.
THERE IS A NARROW BAND OF MOISTURE AHEAD OF THE UPPER WAVE AND
SURFACE FRONT TUESDAY NIGHT ALONG WITH SOME WEAK INSTABILITY.
MOST OF THE PRECIPITATION IS STAYING NORTH OF OUR CWA, BUT DOES
GET INTO OUR NORTHERN SECTIONS OF THE CWA(15-25%).
MUCH ABOVE NORMAL TEMPERATURES TUESDAY-THURSDAY: AHEAD OF THE
FRONT ON TUESDAY, STRONG SOUTH TO SOUTHWEST LOW LEVEL FLOW WILL
BRING TEMPERATURES INTO THE UPPER 60S TO LOW 70S DESPITE THE
INCREASED CLOUD COVER. THE FRONT IS NOT EXPECTED TO COOL THINGS
DOWN FOR WEDNESDAY OR THURSDAY WITH SIMILAR READINGS EACH DAY.
THESE HIGHS MAY APPROACH OR ECLIPSE RECORDS AS WELL AS SOME
POTENTIAL WARMEST LOWS(SEE CLIMATE SECTION FOR THESE RECORDS).
ANOTHER UPPER WAVE AND FRONTAL SYSTEM MAY BRING SOME
PRECIPITATION TO THE AREA LATE IN THE WEEK. THIS FRONT WILL
PROBABLY LOWER TEMPERATURES CLOSER BACK TO NORMAL BY FRIDAY INTO
THE WEEKEND.
