TUESDAY, AT AROUND 7:10 PMish

FROM THE NATIONAL WEATHER SERVICE IN INDIANAPOLIS:

FORECAST FOCUS ON PRECIP CHANCES TONIGHT AND TOMORROW.

THE AFTERNOON SURFACE MAP SHOWS A COLD FRONT LYING ALONG THE OHIO
RIVER VALLEY. HIGH PRESSURE WAS OVER THE CENTRAL PLAINS OF CANADA.
THE H5 PATTERN REMAINS WITH A RIDGE OVER THE WESTERN HALF OF THE
CONUS AND A LARGE UPPER LOW REMAINING OVER THE NORTHEASTERN PART OF
THE COUNTRY.

THE MODELS REMAIN IN FAIRLY GOOD AGREEMENT AND SEEM TO HAVE
INITIALIZED WELL. THE BIG DIFFERENCES ARE AMONG POPS FOR TONIGHT
AND INTO TOMORROW. HAVE SIDED MORE WITH THE GFS ON THIS ONE
CONSIDERING THAT THE LOW LEVELS REMAIN VERY DRY.

FOR TONIGHT THE UPPER LOW WILL SEND ANOTHER VORT MAX HEADED THIS
WAY. THIS MID LEVEL TROUGHING WILL PROVIDE FORCING FOR SOME LIGHT
PRECIPITATION. LOOKING UPSTREAM AT WHERE THE ENERGY IS RIGHT
NOW...SOME LIGHT SHOWERS CAN BE SEEN. WITH THE LOW LEVEL DRY AIR
EVIDENT IN THE SOUNDINGS WILL NOT QUITE GO WITH THE LIKELY POPS
SHOWN ON THE NAM. LOWS TONIGHT WILL BE ON THE COOL SIDE OF THINGS
FOR THE LAST NIGHT OF JUNE...AS THE COLD POOL SLIDES SOUTH AND
SENDS H8 TEMPS INTO THE SINGLE DIGITS. THIS WILL GIVE US LOWS IN
THE MIDDLE TO UPPER 50S.

FOR WEDNESDAY THE COLD POOL WILL PUSH SOUTH INTO CENTRAL INDIANA
AND PROVIDE THE IMPETUS FOR CLOUDS AND SOME ADDITIONAL SHOWERS
TOMORROW. THE RECORD LOW MAXIMUM TEMPERATURE FOR JULY 1 IS 68
DEGREES. THIS IS WITHIN REACH AS WE SEE H8 TEMPS NEAR +9C WHICH
WOULD FULLY MIX TO THE LOW 70S. WITH EXPECTED CLOUDINESS THIS
RECORD COULD BE GIVEN A RUN...BUT ANY BREAKS OF SUN THIS TIME
OF YEAR WILL CAUSE TEMPS TO SHOOT INTO THE 70S. WILL CONTINUE THE
LOW POPS FOR TOMORROW EXPECTING SOME COLD POOL LOW TOPPED
CONVECTION.

OVERNIGHT WILL BE A COOL NIGHT AGAIN AS THE CORE OF THE COLD POOL
SLIDES SOUTHEAST ACROSS INDIANA. THICKNESS VALUES SHOW IT SHOULD
BE A COOLER NIGHT THAN TONIGHT...AND MOS GUIDANCE IS CLUSTERED IN
THE LOW 50S. ONLY THE CLOUDINESS PRESENT SHOULD KEEP TEMPS FROM
FALLING INTO THE 40S.

ON THURSDAY THE UPPER LOW WILL WEAKEN AND SLIDE EAST AND THE
HEIGHTS WILL BEGIN TO RISE. EXPECTING A QUICK MOVING VORT MAX ON
THURSDAY TO PROVIDE CLOUDS...WITH SHOWERS EXPECTED TO STAY SOUTH
OF THE AREA IN CLOSER PROXIMITY TO THE LIFT ASSOCIATED WITH THIS
SYSTEM. TEMPS WILL MODERATE WITH H8 VALUES APPROACHING +12C AGAIN
AND THIS WILL GIVE HIGHS IN THE MID TO UPPER 70S.

OVERNIGHT THURSDAY WILL BE WARMER THAN THE PREVIOUS NIGHT GIVEN
THE HIGHER HEIGHTS PRESENT. WITH CLOUDS AND SOUTHWEST WINDS WILL
SEE READINGS MORE IN THE 60S THAN 50S EXCEPT IN SOME RURAL SPOTS.

ON FRIDAY HEIGHTS WILL CONTINUE TO RISE AND H8 TEMPS WILL APPROACH
+16C IN THE SOUTH. THIS WILL BRING TEMPS BACK INTO THE
80S. WITH INCREASING HUMIDITY AHEAD OF A COLD FRONT IN THE CENTRAL
MISSISSIPPI VALLEY.

THIS FRONT WILL SLOWLY PULL THROUGH THE AREA LATE FRIDAY NIGHT AND
WILL PROVIDE A SLIGHTLY COOLER DAY BY SATURDAY. H8 TEMPS WILL FALL
TO AROUND +13C FOR HIGHS IN THE LOW 80S. WILL MENTION CHANCES OF
SHOWERS AND THUNDERSTORMS ON SATURDAY WITH THE SLOW MOVING COLD
FRONT. PRECIP CHANCES TO DIMINISH OVERNIGHT AS THE FRONT SLIDES
SOUTH AND COOLER AND DRIER AIR ARRIVES FROM THE NORTH.

EXTENDED PATTERN WILL FEATURE ANOTHER UPPER LOW IN THE NORTHEAST
BY EARLY NEXT WEEK. THIS WILL ALLOW FOR BELOW NORMAL TEMPERATURES
INTO THE END OF THE FORECAST PERIOD.
