DISCUSSION
ISSUED AT 133 PM CST WED FEB 19 2025
THROUGH FRIDAY: DANGEROUS COLD CONDITIONS ARE THE KEY HIGHLIGHT
OF THIS FORECAST PACKAGE. AN ARCTIC AIRMASS CONTINUES TO MOVE INTO
THE AREA AND HAS BEEN DEMONSTRATING ITS STRENGTH, WITH OBSERVED
TEMPS BELOW FORECAST EXPECTATIONS ON ESSENTIALLY AN HOURLY BASIS
THROUGH THE DAY TODAY. STRONG COLD ADVECTION WILL CONTINUE THROUGH
THE NIGHT AS NORTHERLY WINDS REMAIN GUSTY AT TIMES. WHILE THIS
MIXING AND A PERSISTENT LOW CLOUD DECK WILL PREVENT TEMPS FROM
FALLING AS MUCH AS THEY MIGHT HAVE OTHERWISE, IT WILL RESULT IN
VERY LOW WIND CHILLS IN THE TEENS ACROSS MOST OF THE AREA, WITH
SOME SPOTS POTENTIALLY SEEING SUBZERO WIND CHILLS BY TOMORROW
MORNING. REFREEZING OF ANY LINGERING MOISTURE IS POSSIBLE TONIGHT,
BUT THE PERSISTENT WIND SHOULD HELP COUNTER THIS BY EXPEDITING
THE DRYING PROCESS.
THE COLD WILL CONTINUE INTO THURSDAY, THOUGH WE SHOULD FINALLY
SEE CLOUDS BEGIN TO DECREASE. STILL, TEMPERATURES MAY NEVER GET
ABOVE FREEZING DURING THE DAY ACROSS PARTS OF NORTH MS, AR, AND
NORTHEAST LA. IT WILL ONCE AGAIN BE RATHER COLD THURSDAY NIGHT,
WITH TEMPS FALLING INTO THE TEENS AND WIND CHILLS FALLING INTO
SINGLE DIGITS AND TEENS. FOR THIS REASON THE CURRENT COLD WEATHER
ADVISORY WILL BE EXTENDED THROUGH FRIDAY MORNING FOR THE ENTIRE
AREA.
THIS WEEKEND: THE SURFACE RIDGE WILL SHIFT EAST OF THE AREA, WITH
A GRADUAL MODERATING TREND IN TEMPS THROUGH SUNDAY. THIS WILL BE
FOLLOWED BY A SOUTHERN STREAM DISTURBANCE WHICH WILL TRACK WELL
SOUTHWARD NEAR THE GULF COAST. THIS WILL SPREAD MAINLY LIGHT RAIN
NORTHWARD ACROSS AREAS PRIMARILY SOUTH OF I-20 FROM EARLY SUNDAY
MORNING THROUGH SUNDAY AFTERNOON OR EARLY EVENING. WHILE
CONDITIONS MAY BE RATHER COOL SHORTLY AFTER SUNSET SATURDAY
EVENING, GUIDANCE SHOWS TEMPERATURES RISING OVERNIGHT SATURDAY
NIGHT AHEAD OF THE RAIN, KEEPING PRECIP IN A LIQUID STATE.
EARLY NEXT WEEK: BROAD SURFACE HIGH PRESSURE WILL BUILD ACROSS
THE CENTRAL CONUS EARLY NEXT WEEK, RESULTING IN DRY WEATHER
CONDITIONS IN OUR AREA AND TEMPERATURES RETURNING TO ABOVE NORMAL
BY THE MIDDLE OF THE WEEK. /DL/
