DISCUSSION

SKIES HAVE CLEARED OUT A BIT THIS AFTERNOON HELPING TO BOOST
TEMPERATURES INTO THE UPPER 70'S TO LOW 80 DEGREES. A MOIST
AIRMASS IS IN PLACE WITH DEWPOINTS IN THE UPPER 60'S/LOW 70'S. A
FRONTAL BOUNDARY REMAINS DRAPED ACROSS SOUTHEAST MISSOURI INTO
SOUTHERN ILLINOIS AND IS HELPING TO DEVELOP ISOLATED SHOWERS
AND STORMS AT THIS TIME. WEAK MID LEVEL LAPSE RATES AND WEAK
SHEAR SHOULD LIMIT SEVERE POTENTIAL THIS AFTERNOON BUT A STRONG
STORM OR TWO CANNOT BE RULED OUT. THE FRONT GRADUALLY MOVES
SOUTH A BIT OVERNIGHT WITH A LULL IN SHOWERS/STORMS. GUIDANCE
HAS PICKED UP ON SOME FOG OR LOW STRATUS DEVELOPING NEAR THE
FRONT OVERNIGHT.
FRIDAY WILL FEATURE MOSTLY ZONAL WESTERLY FLOW ALOFT ACROSS THE
PLAINS AND INTO THE OHIO/TENNESSEE VALLEY. MODELS DEPICT A
SHORTWAVE EMBEDDED WITHIN THIS ZONAL FLOW TO TRAVERSE THE REGION
LATE FRIDAY MORNING INTO FRIDAY AFTERNOON. ITS EXPECTED THAT AN
MCS MAY BE ONGOING FRIDAY MORNING AND WILL CONTINUE TO PUSH
EASTWARD. QUESTIONS STILL REMAIN ON DESTABILIZATION AHEAD OF
THIS CLUSTER OF STORMS BUT MOST GUIDANCE SUGGESTS THAT RENEWED
CONVECTION MAY DEVELOP AS THE REMNANT MCS CIRCULATION MOVES
THROUGH THE AREA. HREF ENSEMBLE MEAN SBCAPE IS PUSHING 2000
J/KG, WITH BULK SHEAR VALUES IN EXCESS OF 40-50 KNOTS, PUSHING
60 KNOTS IN THE LATE AFTERNOON AHEAD OF A 60-70 KNOT MID LEVEL
JET. THIS WOULD SUPPORT ORGANIZED CONVECTION WITH THE PRIMARY
RISK BEING DAMAGING WINDS, OF COURSE A TORNADO OR TWO IS
CERTAINLY POSSIBLE. TIMING UNCERTAINTY REMAINS AND THE LATER
THIS ACTIVITY DEVELOPS INTO THE AFTERNOON, THE HIGHER THE SEVERE
POTENTIAL MAY BE.
ANOTHER UPPER LEVEL WAVE IS ADVERTISED TO MOVE THROUGH ON
SATURDAY. THIS WOULD SUPPORT MORE CHANCES OF THUNDERSTORMS ON
SATURDAY WITH ANOTHER POTENTIAL MCS OR CLUSTER OF SCATTERED
THUNDERSTORMS. THERE IS ENOUGH OVERLAP OF SHEAR AND INSTABILITY
THAT WE WILL NEED TO WATCH FOR STRONG TO SEVERE STORMS WHICH SPC
HAS HIGHLIGHTED IN THE DAY 3 SLIGHT RISK WHICH COVERS PORTIONS
OF SOUTHERN KENTUCKY AND SOUTHEAST MISSOURI. BEYOND SATURDAY,
TROUGHING SETS UP TO OUR NORTH WITH AT LEAST A FEW SHORTWAVES
ROTATING THROUGH CYCLONIC FLOW. ANY OF THESE MAY PRESENT CHANCES
OF SHOWERS AND STORMS BEFORE HIGH PRESSURE MOVES IN FROM THE
NORTHWEST EARLY IN THE WEEK. DRIER WEATHER IS EXPECTED ROUGHLY
TUESDAY THROUGH THURSDAY OF NEXT WEEK WITH HIGHS IN THE LOW TO
MID 80'S.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1246 PM CDT THU JUN 5 2025
A FRONT MOVING ACROSS THE REGION SHOULD RESULT IN SCATTERED
SHOWERS AND STORMS THIS AFTERNOON. THESE MAY BRING TEMPORARY
RESTRICTIONS TO THE TERMINALS. OTHERWISE MVFR CIGS EARLY THIS
AFTERNOON SHOULD QUICKLY RETURN TO VFR FOR THE REMAINING
AFTERNOON AND INTO THE OVERNIGHT. THE FRONT DROPPING SOUTH
OVERNIGHT MAY BRING FOG TO THE TERMINALS OVERNIGHT AND FRIDAY
MORNING. ANOTHER ROUND OF SHOWERS AND STORMS WILL DEVELOP AFTER
12Z OR SO AND PUSH EASTWARD WITH STRONG TO SEVERE STORMS A
POSSIBILITY.
