NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Indianapolis in 
102 PM EST Friday Jan 30 2015 


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


&& 


Synopsis... 
issued at 329 am EST Friday Jan 30 2015 


The main focus of the forecast period will be a storm system 
projected to impact the area mainly early Sunday through Sunday 
night. Models have the system approaching from the southwest and 
it is expected to bring accumulating snowfall beginning late 
Saturday night and continuing before exiting the region Monday morning. 
In the wake of the system...below normal temperatures will prevail 
on Monday with highs only in the teens. Additional precipitation 
chances will be possible on Tuesday night/Wednesday as a cold 
front moves through central Indiana. 


&& 


Near term /rest of this afternoon/... 


Issued at 1239 PM EST Friday Jan 30 2015 


Update...the forecast for the rest of this afternoon only needed a 
few minor tweaks based on latest trends and observations. 
Otherwise it looks pretty much on track. 


On a more noteworthy subject...a Winter Storm Watch was issued. To 
be clear...*not* for this period. Specifically for the time frame 
of Saturday evening through early Monday morning for counties 
roughly around and northward of the I-70 corridor. More 
discussion/explanation on why this was issued will come in 
subsequent afd updates...but for now this product and further 
information can be found on our website and under the product Idaho 
wswindwsw. 


The previous discussion follows. 


High pressure will result in benign conditions for the near term 
period. The only exception will be some possible early morning 
lake effect snow showers over the northern counties...but no 
accumulations are expected. As subsidence strengthens through the 
course of the day...stratocumulus should break up by this 
afternoon. Highs will range from the upper 20s to middle 30s from 
north to south...stuck close to guidance. 


&& 


Short term /tonight through Sunday night/... 


Issued at 329 am EST Friday Jan 30 2015 


The main focus of the short term period is snowfall amounts with 
system prognosticated for Sunday/Sunday night. 


First...partly cloudy skies and calm conditions will prevail 
tonight through Saturday. However...clouds will increase across 
the forecast area on Saturday afternoon as a storm system 
approaches from the Central Plains. GFS/Euro/NAM are all in decent 
agreement with the track of this system...taking the 700 mb low 
across central Indiana. The outlying model at this time is the 
Euro...which takes the track just slightly more north than the GFS 
and NAM. Either way though...expect significant snow accumulations 
over central and northern portions of central Indiana as swath 
between -2c and -8c isotherms at 850 mb lines up over the northern 
two-thirds of the forecast area. In addition...1000-500mb thickness 
lines of all 3 models point to the central and northern counties. 
Confidence is slightly lower for the southern counties which could 
receive some wintry mix with just the slightest shift of track to 
the North. 


Western counties could start seeing some snowfall around sun 
00z...but isentropic lift really strengthens after sun 06z. So 
current thinking is heaviest snow will fall between sun 12z-Monday 
00z...quickly tapering off by Monday 06z. 


Temperatures...generally stuck close to model blend with a few tweaks. 
Trended slightly warmer on Saturday due to southwesterly surface 
flow ahead of aforementioned system. This will help bump highs up 
into the upper 30s. Temperatures will fall back to normal on Sunday 
though as winds back to the east...and plummet into the single 
digits on Sunday night as winds become northerly. 


&& 


Long term /Monday through Thursday/... 
issued at 328 am EST Friday Jan 30 2015 


Much quieter weather will be the rule during the long term. The 
system which will bring long snow Sunday will be moving off the 
middle Atlantic coast Monday and high pressure over the upper 
Midwest will move across our region late Monday and Monday night. 
Monday and Monday night will be dry and quite cold. Tuesday will be 
dry and a little warmer as this high pressure moves on to the east 
and a southerly flow develops across our region. 


Both the GFS and gemnh model brings a cold front across our region 
Wednesday while the Euro is about 18 to 24 hours slower. Prefer the 
faster GFS and gemnh model as the Euro seems to hold up the next 
surge of Arctic air too long. 


Will mention a chance of light snow late Tuesday night and Wednesday 
with the cold front. Far southern sections may see a period of 
mixed precipitation on Wednesday as low level thickness rise to near 
or slightly above critical values. 


I have low confidence there will be any precipitation Wednesday night even 
though some of the guidance indicates this. For now will only 
mention a chance of flurries for Wednesday night. 


Lowered temperatures a little Monday and Tuesday as most areas will 
have a pretty good snow cover. Otherwise...a MOS blend on 
temperatures seem reasonable for most other periods. 


&& 


Aviation /discussion for the 301800z taf cycle/... 


Issued at 1257 PM EST Friday Jan 30 2015 


Expect VFR conditions to continue...but just barely...at all taf 
sites during this cycle. Current deck of clouds over laf/ind are 
just slightly in the VFR category with broken/over ceilings in the 
3100 to 3300 foot range. There are a couple observation upstream of these 
two sites that are depicting ceilings at or below 3000 feet...however 
those sites are more entrenched within the current cloud mass. 
With laf/ind being on the western fringe...decided to keep them 
VFR. Not currently dealing with much cloud cover over huf/bmg. 
However...would not be surprised if bmg GOES scattered this 
afternoon. Expect this band of clouds from laf to ind and eastward 
to scatter later this afternoon and evening as drier air moves in. 


Then the focus turns to Saturday afternoon and the approach of the 
next weather system. Expect some lower ceilings to move into the 
area toward the end of the taf cycle. However...do believe that the 
lower MVFR/IFR ceilings will hold off until after this particular 
taf cycle. 


As high pressure continues to approach from the west...expect north 
winds to continue to decrease and become light tonight. Increasing 
back to around 8 to 10 knots out of the southwest Saturday 
afternoon.
