NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Indianapolis in 
1019 PM EDT Wednesday Aug 20 2014 


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


&& 


Synopsis... 
issued at 245 PM EDT Wednesday Aug 20 2014 


A ridge of high pressure will strengthen over the eastern third of 
the nation through the course of the forecast period...bringing 
the hottest weather of the Summer. Highs will soar into the low 
90s by the end of the week. However..weak waves will rotate 
around that ridge...keeping chances for showers and thunderstorms 
over central Indiana through the short term period. A surface warm 
front will also provide additional lift for convective development 
through Saturday as it stalls over northern Indiana. 


&& 


Near term /rest of tonight/... 


Issued at 1007 PM EDT Wednesday Aug 20 2014 


Chances for storms will increase across the area after 06z as a warm 
front slowly moves north into the area and a low level jet ramps up 
to the west. Short range models continue to indicate some potential 
for convective development along the front as well as potential for 
some development in southern Minnesota/northern Iowa that could move 
into the northern counties very late in the tonight period into 
Thursday morning. Made only small adjustments to going probability of precipitation to keep 
the forecast dry for another hour or two before having a slight 
chance and then increasing chances after 6z. Still a relatively 
large spread in potential solutions for the overnight and thus lower 
than average confidence for the overnight. 


Temperatures...cloud cover due to frontal boundary over the area will 
keep temperatures in the upper 60s/low 70s tonight. The NAM seemed to be 
over doing cloud cover for most of the near and short term 
periods. So...leaned toward the slightly lower temperatures of the GFS. 


&& 


Short term /tomorrow through Saturday/... 


Issued at 245 PM EDT Wednesday Aug 20 2014 


The main focus of the short term is hot temperatures and scattered 
showers and thunderstorms. 


Environment will destabilize tomorrow as warm advection spreads 
over central Indiana behind front...triggering showers and 
thunderstorms. The highest chances will be over the northern 
counties where additional forcing from the front will aid in 
convective development. As a result...carried likely probability of precipitation over 
that area tomorrow. 


High pressure will continue to strengthen over the area for the 
remainder of short term period...but weak waves in the flow will 
drift along the ridge...keeping chances for showers and 
thunderstorms in the forecast through Saturday. 


Temperatures...the highest temperatures of the season will commence during this 
forecast period with highs reaching into the low to middle 90s on 
Friday and Saturday. Trended on the warmer side of guidance due to 
persistent southwest flow. 


&& 


Long term /Saturday night through Wednesday/... 


Issued at 245 PM EDT Wednesday Aug 20 2014 


Models continue to indicate some of the warmest weather this season 
as a strong upper ridge builds over the middle Mississippi Valley 
by this weekend and then shifts to the Ohio Valley by Monday and then 
weakening some by the middle of next week which will allow a cold 
front to move south into our area. Models indicate 850 mb 
temperates of +20 to +22 celsius and 700 mb temperatures near +10 
mb which may leave US pretty well capped Sunday and Monday. 


Guidance temperatures indicate highs in the lower to middle 90s. But 
due to the wet ground conditions initially...will shave 1-2 degrees 
off high temperatures. Temperatures will begin to moderate a little 
Tuesday and even Wednesday as the upper ridge breaks down some. 
There are some differences between models on how much of this occurs. 
However will lean towards model consensus for now. 


&& 


Aviation /discussion for 210300z taf update/... 
issued at 1019 PM EDT Wednesday Aug 20 2014 


Only minor changes for the update as conditions remain tranquil this 
evening. Middle and high level clouds continue to drift across the 
forecast area. As the low level jet strengthens overnight...still 
anticipate scattered convective development sometime after 
06z...with the potential for more widespread storms arriving from 
the northwest towards daybreak. 


00z discussion follows. 


MVFR visibilities possible late tonight with fog. Restrictions 
possible in any convection overnight and Thursday morning. 


Very low confidence convective forecast into Thursday. Weak 
surface ridging has developed over central Indiana in the wake of 
the afternoon storms with just middle/high level clouds drifting 
through. Most of the storms are now focused near the remnant 
surface boundary...extending west/northwest from convective complex over the 
Tennessee Valley back into western Kentucky. The boundary will 
begin to lift back north overnight as the next upper level wave 
over the Missouri Valley early this evening shifts east towards 
the region. 


The combination of these features along with a low level jet 
nosing into central Indiana should support convective development 
primarily after 06z. High uncertainty however exists in extent to 
convective coverage and specific impacts to terminals. It appears 
kind and klaf will stand the best chance at storms late with 
slightly lower threats at kbmg and khuf. While instability is 
likely to recover overnight...uncertainty in coverage and timing 
makes it difficult to go any higher than thunderstorms in the vicinity at this point. 


Upper ridging will attempt to expand across the forecast area 
Thursday as the upper wave departs. Potential exists for isolated/ 
scattered storms to redevelop Thursday afternoon during peak 
heating...but will keep conditions dry at this time. Southwest 
winds to around 10kts possible Thursday.
