DISCUSSION
AFTER A COOL START THIS MORNING, TEMPERATURES ARE
EXPECTED TO WARM INTO THE MID-TO-UPPER 60S AND LOW 70S ACROSS
SOUTHERN INDIANA AND CENTRAL KENTUCKY THIS AFTERNOON. HIGH
PRESSURE WILL SLIDE ACROSS THE GULF STATES TODAY, CAUSING WINDS TO
PICK UP OUT OF THE SOUTH-SOUTHWEST BY THIS AFTERNOON. THE SETUP
TODAY DOES LOOK SOMEWHAT FAVORABLE FOR DRY AIR MIXDOWN, SO
RELATIVE HUMIDITY VALUES COULD END UP FALLING INTO THE 20S AND LOW
30S THIS AFTERNOON. A SUBSIDENCE INVERSION AROUND 4 KFT AGL WILL
KEEP MIXING HEIGHTS SOMEWHAT LIMITED TODAY, BUT INCREASING
TRANSPORT WINDS LATER TODAY WILL IMPROVE DISPERSION CONDITIONS.
LATE TONIGHT INTO TUESDAY MORNING, ANOTHER COLD FRONT WILL MOVE
ACROSS THE REGION, BRINGING A VERY SLIGHT CHANCE FOR A RAIN
SHOWER. BREEZY CONDITIONS WILL CONTINUE BEHIND THE FRONT ON
TUESDAY AND WEDNESDAY, WITH TEMPERATURES FALLING BACK BELOW NORMAL
BY WEDNESDAY.
THURSDAY WILL BE DRY WITH FAIRLY LIGHT WINDS AS HIGH PRESSURE
BUILDS ACROSS THE REGION. THURSDAY NIGHT INTO FRIDAY ALSO LOOKS
DRY AS HIGH PRESSURE STARTS TO SLIDE OFF TO THE EAST. RAIN CHANCES
WILL INCREASE FRIDAY NIGHT INTO SATURDAY AHEAD OF A LOW PRESSURE
SYSTEM TO THE WEST. CLOUDS AND RAIN SHOWERS WILL MOVE INTO THE
REGION FOR SATURDAY, WITH 5-10 MPH WINDS FROM THE SOUTHEAST.
TEMPERATURES ARE FORECAST TO TOP OUT IN THE LOW TO MID 60S
SATURDAY AFTERNOON.
