NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Indianapolis in 
424 am EDT sun Aug 31 2014 


Update...the aviation section has been updated below. 


&& 


Synopsis... 
issued at 322 am EDT sun Aug 31 2014 


Rain chances will diminish today as an upper disturbance moves off 
to the east. However chances for rain will return for Labor Day and 
Tuesday as an upper trough and surface cold front move into the 
area. After a brief break Wednesday...rain chances will return late 
week into next weekend as more fronts move in. Temperatures will 
remain near to above average. 


&& 


Near term.../today/ 
issued at 322 am EDT sun Aug 31 2014 


Numerous showers and isolated thunderstorms continue across the 
northwest forecast area...while scattered showers continue across 
the southeast early this morning. Expect forcing to decrease across 
the northwest during the remainder of the morning as an upper 
disturbance begins to move east. 


By 12z expect best chances for rain to be across the southeast 
forecast area where more forcing will be. Will go likely probability of precipitation far 
southeast. Hi res rapid refresh still shows scattered convection 
across the remainder of the area this morning so will keep chance 
category probability of precipitation elsewhere. 


Chances for rain will diminish during the afternoon as forcing 
continues to weaken. Will gradually lower probability of precipitation through the 
afternoon. 


MOS looks pretty reasonable for temperatures most areas with some 
decrease in clouds expected during the afternoon. 


&& 


Short term.../tonight through Tuesday night/ 
issued at 322 am EDT sun Aug 31 2014 


Focus is on chances for rain through the period. NAM is not doing 
well with today/S precipitation so didn/T really trust it for the 
remainder of the forecast. Used a blend of other models. 


Will continue low probability of precipitation southeast during the night to account for any 
lingering rain behind the departing upper system. 


On Monday the next upper trough and surface cold front will begin to 
approach the area. Gradually increased probability of precipitation during the day from 
northwest to southeast but kept them in chance category for now as 
best forcing doesn/T arrive until Monday night. 


On Monday night 850mb winds will have increased to 30-40kt...and the 
area will be in the right rear quadrant of an 100kt upper jet. This 
forcing combined with plentiful moisture will lead to likely probability of precipitation 
most areas. Shear and instability look sufficient for severe 
potential late Monday afternoon into Monday night. 


Cold front will move in on Tuesday but the aforementioned upper 
forcing will diminish. Will go likely probability of precipitation early across the east 
with chance probability of precipitation elsewhere. Probability of precipitation will decrease during the afternoon 
as forcing continues to weaken...but will still remain in chance 
category. 


Kept low probability of precipitation Tuesday evening to account for any lingering rain 
behind the system and then dry overnight. 


Trended toward the warmer of the MOS highs on Monday with rain not 
arriving until later in the day. Mav looks too warm on Tuesday with 
cold front moving through so cut it as needed. For overnight lows 
through the period stuck with a blend. 


&& 




Long term /Wednesday through Saturday/... 
issued at 255 am EDT sun Aug 31 2014 


Main focus on the long term will continue to be on probability of precipitation and 
temperatures. 


The deterministic European model (ecmwf) continues the trend of siding better with 
the ensemble blend compared to the GFS with the 00z Euro faster to 
bring a cold front southeast across the area next weekend. 
Otherwise...extended models agree on expanding upper southern ridge 
to the Ohio Valley on Wednesday which should result in a cold front 
dying across the Ohio Valley. Would not rule out a a few 
thunderstorms...however with the ridge building across the 
area...will go with dry weather Wednesday and Wednesday night. 
Then...will be bringing probability of precipitation back by Thursday ahead of the weekend 
cold front and upper trough. Best chances looks to be Friday through 
Saturday. 


It will be very warm and humid middle to late week with the ridge over 
the area. Temperatures could reach the lower 90s south Thursday and 
Friday with heat indices near 100 per regional blend. Then...the 
cold front will start to bring not as warm and drier air in late in 
the weekend.

Aviation /discussion for 310900z ind taf update/... 


Issued at 424 am EDT sun Aug 31 2014 


Taf looks good...no changes needed. 


Previous discussion follows... 


Klaf could get east enough to impact klaf within the next couple of 
hours and will continue to carry thunderstorms in the vicinity there with tempo thunder for a 
couple of hours. At khuf and kind think dry weather will prevail 
through the night. Expect more widespread lower ceilings /around 
1500 feet/ later during the overnight and with the humid air mass 
could see some visibility reductions as well but still MVFR. Lower 
ceilings could hang around until afternoon before scattering up. 


Winds should remain out of the south-southwest through the overnight around 5-10 
kts.
