THE REMNANT MCV IS PUSHING THROUGH THE EASTERN PORTION OF THE REGION
THIS AFTERNOON BRINGING A LINE OF MODERATE SHOWERS THROUGH OUR FAR
EASTERN COUNTIES. AS THIS MCV CONTINUES TO PUSH EAST, SKIES WILL
STEADILY THIN AND LIFT.
WINDS WILL REMAIN LIGHT OVERNIGHT AND THIN UPPER SKY COVER WILL MOVE
OVER THE REGION. SOME PATCHY FOG DEVELOPMENT IS POSSIBLE, ESPECIALLY
IN AREAS THAT RECEIVED AMPLE RAIN OVER THE LAST FEW DAYS. WE WILL
LIKELY SEE MORE EFFICIENT COOLING TONIGHT BRINGING LOW TEMPERATURES
INTO THE WIDESPREAD 60S.
IN THE EARLY MORNING, A COLD FRONT WILL ENTER THE REGION FROM THE
NORTHWEST MOVING SOUTHEAST. ALONG AND AHEAD OF THE COLD FRONT, A
LINE OF SHOWERS AND STORMS WILL ALSO MOVE THROUGH. THE LINE OF
SHOWERS WILL MOVE INTO SOUTHERN INDIANA AROUND 12Z. TOWARDS THE
AFTERNOON, THE UPPER TROUGH WILL BEGIN TO SWING OVER THE REGION AND
MID-LEVEL FLOW WILL INCREASE ALLOWING FOR STORMS TO DEVELOP ALONG
AND EAST OF I-65. SBCAPE OVER THIS REGION WILL INCREASE TO ABOUT
1200-1400J/KG IN THE AFTERNOON AND THERE WILL BE ABOUT 30-35KTS OF
DEEP LAYER SHEAR, ENOUGH TO SUSTAIN STORMS FOR MARGINAL
ORGANIZATION. SCATTERED STRONG TO DAMAGING WINDS WILL BE POSSIBLE,
ALONG WITH HAIL, LIGHTNING, AND HEAVY RAIN. LOW LEVEL SHEAR IS QUITE
WEAK, THEREFORE THE TORNADO THREAT IS VERY LOW. THE LINE OF SHOWERS
WILL PUSH EAST OF THE REGION BY SUNSET.
LONG TERM /MONDAY NIGHT THROUGH SUNDAY/
ISSUED AT 318 PM EDT SUN JUN 8 2025
MONDAY NIGHT THROUGH THURSDAY...
UPPER TROUGHING WILL PUSH THROUGH THE REGION MONDAY NIGHT BRINGING A
SURFACE HIGH PRESSURE INTO THE REGION THROUGH WEDNESDAY NIGHT. HIGHS
ON TUESDAY WILL BE COOLER THAN NORMAL IN THE UPPER 70S AND LOW 80S.
THEN WARMING ON WEDNESDAY AND THURSDAY TO THE MID-UPPER 80S AS
RIDGING BEGINS TO GROW OVER THE OHIO VALLEY. LOWS WILL BE IN THE MID-
UPPER 50S OVER MOST OF THE AREA WITH URBAN AREAS IN THE LOW 60S.
VERY PLEASANT CONDITIONS FOR TUESDAY THROUGH THURSDAY.
THURSDAY NIGHT THROUGH SUNDAY...
BY LATE WEEK, THE PATTERN TURNS QUITE MESSY WITH MOSTLY ZONAL FLOW
OVER THE REGION, RIDGING TO THE SOUTH, AND A WAVE FORMING OVER THE
SOUTHERN PLAINS. THE SOUTHERN PLAINS WAVE HAS BEEN A CONSISTENT
SIGNAL MOVING INTO THE OHIO VALLEY. THIS FEATURE MAY DEEPEN SOME AS
IT MOVES ACROSS THE REGION. SOUTHERLY FLOW WILL BEGIN TO PUMP IN
GULF MOISTURE BRINGING PWATS UP TO 2.0 INCHES AND INCREASING
INSTABILITY. THIS WILL ALLOW FOR SHOWERS AND STORMS TO MOVE THROUGH
THE AREA. SOME STORMS MAY BECOME STRONG.
HIGHS WILL BE NEAR NORMAL IN THE MID TO UPPER 80S AND LOWS WILL BE
NEAR NORMAL TO SLIGHTLY ABOVE NORMAL.
