NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Indianapolis in 
957 am EDT Sat Sep 5 2015 


Update... 
the near term section has been updated below 


&& 


Synopsis... 
issued at 333 am EDT Sat Sep 5 2015 


Weak but hot high pressure in place over the Ohio Valley will 
provide warm and humid weather through the Holiday weekend. 
Isolated showers and thunderstorms will be possible each afternoon 
through the weekend...however most areas will remain dry...hot and 
humid. A weak cool front is expected to pass across the area on 
Monday night and this will bring some relief to the heat and 
humidity during the next work week. 


&& 


Near term /this afternoon/... 


Issued at 957 am EDT Sat Sep 5 2015 


Surface analysis continues to show weak surface high pressure in 
place across Appalachia...extending eastward into the Ohio 
Valley. A weak upper disturbance was found over NE 
Illinois...helping to generate some scattered thunderstorms and rain over northwest parts 
of our forecast area. 


Forecast soundings show convective temperatures in the upper 80s and 
plenty of cape with vales in excess of 2000 j/kg this afternoon. 
Furthermore...after yesterday/S convection...several weak surface 
boundaries are probably in place across central Indiana. Thus will 
expected scattered thunderstorms and rain development this afternoon as convective temperatures 
are reached. Rapid refresh depicts convection possible a bit more 
to the south and east than the ongoing forecast suggested. Thus 
have raised probability of precipitation slightly and expanded the possible area for thunderstorms and rain 
to the south and east this afternoon. 


Will not expected middle 90s today for highs as yesterday/S rain 
cooled the column a bit...and we are already running cooler than 
yesterday. Kept highs close to the low 90s. Ongoing forecast 
handles that well. 


&& 


Short term /tonight through Monday night/... 


Issued at 333 am EDT Sat Sep 5 2015 


Since the weather pattern will remain the same through almost 
this entire period...persistence forecasting was utilized once 
again for tonight through early Monday. The only difference is 
that Sunday looks dry at this time as convective temperatures (per 
model soundings) will be a little harder to attain...and the 
instability really plummets by Sunday afternoon. Without another 
forcing mechanism it will be hard to develop diurnally charged 
convection on Sunday and have thus gone with a dry forecast during 
this time. 


A cool front will slowly begin to drop in the northwest counties 
of the forecast area very late Monday night. Left in low chance 
probability of precipitation across the far northwest as this cool front feature appears 
to be extremely slow with it's progression...and may actually 
stall for a period before crossing central Indiana later Tuesday 
afternoon into Tuesday night. 


As for temperatures...once again trended toward a persistence 
forecast with highs in the upper 80s to low 90s...and lows 
generally in the upper 60s to around 70. 


&& 


Long term /Tuesday through Friday/... 


Issued at 333 am EDT Sat Sep 5 2015 


An upper trough will slowly work it/S way across the country during 
the long term and a front will stall across central Indiana after 
its arrival Tuesday night. This will keep chances for thunderstorms 
in the forecast through the entire long term period. Right now the 
best chances for thunderstorms are centered on Tuesday night and 
Wednesday as the front moves into and across the area before 
stalling. Tuesday night also has the added bonus of a 30-40 knots low 
level jet to enhance the forcing. 


The arrival of the upper trough will also usher in cooler 
temperatures...with highs in the middle 80s to lower 90s Tuesday 
falling to the upper 70s to lower 80s Wednesday through Friday. 


&& 


Aviation /discussion for 051200z taf issuance/... 


Issued at 648 am EDT Sat Sep 5 2015 


Could see a brief drop to MVFR visibilities at the outlying sites 
over the next hour or two but that should mix out with sunrise. A 
few storms have popped up northwest of klaf and these are drifting 
slowly southeast so will include a thunderstorms in the vicinity there for a few hours this 
morning. Storm Prediction Center srefs show some potential for this to hold together 
enough to possibly impact kind sometime after 16-17z. Not 
confident enough on timing or placement for explicit thunder 
mention but given current radar loop...evolution of storms 
yesterday evening...and coordination with cwsu will include a thunderstorms in the vicinity 
at kind as well. Probability is not high enough to include at kbmg 
and khuf at this time. 


Apart from that sites today should be VFR with mainly scattered VFR 
cumulus. During the overnight winds will drop to near calm again but 
forecast sounds are not showing low level saturation. Given lack 
of much fog around this morning will completely leave it out of 
tomorrow morning.
