AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
200 PM EDT MON AUG 10 2015

.UPDATE...
THE LONG RANGE SECTION HAS BEEN UPDATED BELOW

&&

.SYNOPSIS...
ISSUED AT 211 AM EDT MON AUG 10 2015

A WEAK AREA OF LOW PRESSURE WILL EXIT CENTRAL INDIANA TODAY. THIS
WILL KEEP SOME CLOUDS ALONG WITH SOME LOW CHANCES FOR LIGHT RAIN
SHOWERS ACROSS THE AREA TODAY. ANY PRECIPITATION...IF IT OCCURS...SHOULD
BE RATHER LIGHT.

HIGH PRESSURE OVER THE UPPER MIDWEST WILL THEN SETTLE ACROSS
CENTRAL INDIANA TONIGHT AND THROUGH THE REST OF THE WORK WEEK.
THIS WILL RESULT IN DRY AND PLEASANT WEATHER ALONG WITH BELOW
SLIGHTLY NORMAL TEMPERATURES.

&&

.NEAR TERM /REST OF TODAY/...

ISSUED AT 1000 AM EDT MON AUG 10 2015

WITH THE MORNING UPDATE FOLLOWED HI RES MODEL TRENDS TO INCREASE
POPS TO CHANCE CATEGORY ACROSS THE NORTHEAST FOR LATE THIS MORNING
AND THROUGH THE EARLY AFTERNOON WITH THE COLD FRONT MOVING
SOUTHEAST THROUGH THE AREA AND INTERACTING WITH A VERY MOIST
ATMOSPHERE. BEST DYNAMICS REMAIN NORTH AND SOUTH OF CENTRAL
INDIANA SO LEFT SLIGHT CHANCE POPS ACROSS MUCH OF THE AREA.
INCREASED HIGH TEMPERATURES IN THE SOUTH BY A COUPLE DEGREES BASED
ON YESTERDAY/S HIGHS AND SOME WARM ADVECTION OCCURRING AHEAD OF
THE COLD FRONT.

&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...

ISSUED AT 211 AM EDT MON AUG 10 2015

MODELS REMAIN CONSISTENCE DURING THIS PERIOD AS STRONG RIDGING
CONTINUE TO DOMINATE THE UPPER FLOW ACROSS THE WESTERN UNITED
STATES. THIS RESULTS IN A HIGHLY AMPLIFIED PERIOD FOR THE WEEK
WITH LEE SIDE NORTHWEST FLOW SPILLING INTO THE UPPER MIDWEST AND
THE OHIO VALLEY. GFS AND NAM ALSO SUGGEST STRONG HIGH PRESSURE
SETTING UP OVER THE PLAINS STATES...SPREADING IT/S INFLUENCE EAST
ACROSS THE GREAT LAKES AND THE OHIO VALLEY THROUGH AT LEAST
WEDNESDAY NIGHT. FORECAST SOUNDINGS DRY OUT THROUGH THE PERIOD
WITH UNREACHABLE CONVECTIVE TEMPS. BY TUESDAY AND INTO
WEDNESDAY...THE RIDGE TO THE WEST IS SO DOMINATE THAT ANY RIDGE
RIDING DYNAMICS ARE PUSHED WELL NORTHEAST TO ONTARIO...QUEBEC AND
THE NORTHEASTERN UNITED STATES. THUS WILL TREND TOWARD A DRY
FORECAST DURING THIS PERIOD...ALONG WITH ONLY A FEW PASSING HIGH
CI FROM TIME TO TIME. GIVEN THE NORTHWEST FLOW AND LIGHT WINDS
WILL TREND DAILY LOWS AT OR BELOW MAVMOS AS WELL AS HIGH
TEMPERATURES.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...

ISSUED AT 200 PM EDT MON AUG 10 2015

THE EXTENDED WILL START OFF WITH A HIGH AMPLITUDE UPPER DOME OF HIGH
PRESSURE OVER THE SOUTHERN ROCKIES AND SURFACE HIGH PRESSURE OVER
THE OHIO VALLEY. WOULD NOT RULE OUT A THUNDERSTORM OR TWO FRIDAY
NIGHT AS A WEAK FRONT DROPS SOUTHEAST OVER THE AREA.
EVENTUALLY...PACIFIC NORTHWEST UPPER LOW WILL SUPPRESS THE UPPER
RIDGE AS IT SUBSEQUENTLY OPENS UP INTO A WAVE AND MOVES ACROSS THE
LAKE SUPERIOR AREA LATE IN THE WEEKEND AND EARLY NEXT WEEK. THIS
WAVE WILL ALSO FORCE A FRONTAL SYSTEM SOUTHEASTWARD ACROSS THE GREAT
LAKES. THIS COULD BRING A SECOND CHANCE OF THUNDERSTORMS TO THE AREA
ON MONDAY. OTHERWISE...SURFACE HIGH PRESSURE SHOULD KEEP IT DRY.

MODEL THICKNESSES SUGGEST NEAR NORMAL TEMPERATURES THROUGH THE
PERIOD WITH HIGHS IN THE 80S AND LOWS IN THE 60S.
