A 984 MB SURFACE LOW, CENTERED ALONG THE SOUTH DAKOTA AND
MINNESOTA BORDER, WILL CONTINUE EAST TODAY. AS A RESULT, ITS
ATTENDANT COLD FRONT WILL MOVE INTO THE UPPER MISSISSIPPI VALLEY
BEFORE LOSING STEAM AND WASHING OUT JUST TO OUR NORTHWEST. THE
REMNANTS OF THIS FRONT WILL BE PICKED UP BY A SHORTWAVE MOVING
OUT OF THE ROCKIES TONIGHT. A TIGHTENING PRESSURE GRADIENT WILL
DEVELOP THURSDAY MORNING, PRODUCING WIND GUSTS NEAR 40 MPH IN
PORTIONS OF NORTHEAST ARKANSAS AND THE MISSOURI BOOTHEEL. AS A
RESULT, A WIND ADVISORY WILL GO INTO EFFECT AT 9AM. IN ADDITION
TO GUSTY WINDS, ISOLATED SHOWERS WILL IMPACT THE MID-SOUTH
THROUGH THURSDAY EVENING. THERE IS POTENTIAL FOR A FEW
THUNDERSTORMS TOMORROW JUST BEFORE SUNSET, MAINLY IN NORTHEAST
MISSISSIPPI. HOWEVER, UPSCALE GROWTH OF THIS ACTIVITY WILL BE
LIMITED WITH RAINFALL TOTALS MAXING OUT AT A QUARTER OF AN INCH.
RAIN CHANCES WILL WANE FRIDAY MORNING AS THE AFOREMENTIONED FRONT
PUSHES THROUGH THE REMAINDER OF THE MID-SOUTH.
AN UNSETTLED SYNOPTIC PATTERN WILL EMERGE ON SATURDAY AS MULTIPLE
SHORTWAVES IMPACT CENTRAL CONUS. THIS REGIME WILL INCREASE RAIN
CHANCES IN THE MID-SOUTH BY SUNRISE SATURDAY. COVERAGE OF SHOWERS
WILL BE ISOLATED IN NATURE WITH RAIN TOTALS REMAINING LESS THAN
HALF AN INCH. BY SUNDAY, MUCH COOLER AIR WILL BE IN PLACE WITH
HIGHS IN THE 40S AND 50S. THE COOLEST DAY WILL BE MONDAY AS HIGHS
REMAIN IN THE LOW TO MID 40S. SEASONABLE TEMPERATURES WILL NOT
LAST LONG AS UPPER LEVEL RIDGING BUILDS INTO THE MID-SOUTH ON
TUESDAY. A WARMING TREND WILL KICK OFF AT THIS TIME WITH HIGHS
REACHING THE 60S BY MIDWEEK.
LONG-TERM GUIDANCE SUGGESTS ADDITIONAL RAIN CHANCES MATERIALIZING
BY THE END OF NEXT WEEK, THOUGH LARGE MODEL SPREAD AND RUN-TO-RUN
INCONSISTENCIES KEEP CONFIDENCE IN TIMING AND IMPACTS LOW.
