NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
411 PM CST Friday Dec 19 2014 


Short term... 
237 PM CST 


Through Saturday... 


Unfortunately it looks like we will remain locked in the clouds yet 
again tonight...despite a clearing wedge that extends from 
westcentral Illinois to southern in. With high pressure overhead the 
ability to mix to the surface drier air has been nonexistent. With the 
considerable solar shielding this afternoon...surface temperatures have been 
unable to warm much. Temperatures in most locations have remained around 30 
to a few low 30s across the far southern County warning forecast area. Overnight the surface 
ridge will drift east...allowing light/vrb winds to slowly turn 
southwesterly by daybreak Sat. Overnight lows will generally be in 
the low/middle 20s...but if clouds remain thick enough it is plausible 
that temperatures could hold in the middle/upper 20s. Guidance has indicated a 
weak lobe of vorticity along the northern stream pushing east across 
the northern plains overnight...arriving across the Great Lakes 
region around Sat morning. While it appears most of the near surface 
will remain dry...there is some weak forcing in the middle-levels along 
with marginal saturation that some flurries could occur during the 
morning hours. With yet another day of continued cloudiness Sat...it 
appears less favorable for any bump to the temperatures. So have nudged 
temperatures down a degree to the middle 30s across the County warning forecast area. 


Saturday night will generally remain dry...however there is another 
weak vorticity trying to lift northeast across Iowa late Sat night/early 
sun. With a slight warm layer trying to lift across the 
region...however have held onto mainly light snow. There is some 
concern that temperatures aloft could be warm enough to fully melt any 
dendrites. The other concern Worth mentioning is that the lift/Omega 
is lacking late Sat night...so droplet size could be small and instead 
of any dendrites there could end up being patchy freezing 
drizzle...mainly after midnight.

Long term... 
237 PM CST 


Sunday through Saturday... 


500mb trough will begin to dig south across the central Continental U.S. Sun 
into Monday...with a series of middle-level vorts prognosticated to slide southeast 
across the Canadian rockies into the northern plains. The main focus 
will be on a stronger shortwave developing Sun night/early Monday across 
the Dakotas...expected to slide southeast across northern Illinois. 
Although confidence in the timing/placement of this path is low 
given continued corrections based on the latest guidance cycles. 


Moisture will be advecting north of this low Monday...with precipitation 
arriving Monday morning likely as mainly rain or perhaps a rain/snow 
mix across the northern County warning forecast area. Then a quick push of much warmer air 
will bring temperatures into the upper 30s/near 40 Monday afternoon and should turn 
any precipitation to plain rain. As Monday night progresses...the low is prognosticated 
to steadily deepen and lift northeast across northern Illinois early Tuesday. 
Frontal passage currently prognosticated for Tuesday evening...bringing colder air back into 
the forecast area and turning rain over to light snow. 


Monday night with the warm air steadily advecting north...temperatures will 
remain in the middle/upper 30s. Tuesday temperatures could push even 
warmer...depending on the placement/timing of frontal passage. Current 
indications are that temperatures will push into the low/middle 40s Tuesday afternoon. 


Christmas evening through Christmas day... 
ensembles along with operational solutions have been targeting the 
system becoming wrapped up over the Great Lakes region and possibly 
transitioning into another low over southern Ontario/southwest 
Quebec Christmas day. A tight gradient will remain over the region 
both Christmas evening/Christmas day...with temperatures returning to more 
seasonal conditions in the low/middle 30s.

//Ord and mdw concerns...updated 22z... 


* MVFR ceilings. 


Ed f 


//discussion...updated 18z... 


Relatively unchanging conditions are expected to continue through 
the taf period with primarily MVFR ceilings and light winds. Winds this 
afternoon are generally 5 knots or less and out of the north or 
northwest...but will likely become more variable and possibly calm 
for a period this evening and overnight...before southerly winds 
start to creep in behind the high tomorrow. While a few breaks in 
the clouds may develop...expect MVFR ceilings to generally remain locked 
in under a strong inversion with some lowering overnight.

//outlook for Ord/mdw for 00z Sunday-12z Friday...updated 12z... 


Saturday night...MVFR likely. Light south winds. 


Sunday...slight chance flurries/freezing drizzle early. MVFR likely. 
South-southeast winds. 


Monday and Tuesday...chance of rain...especially Monday night. MVFR 
likely. Southeast winds Monday becoming southwest Tuesday. 


Wednesday...chance of snow. MVFR possible. Gusty west winds. 


Thursday...dry. VFR.

Marine... 
200 PM CST 


High pressure is over the region and it will slowly shift east 
through Sunday night. Light winds become southwest overnight. The 
next low moves over the Dakotas Sunday night with south winds 
increasing to 30 knots. Models disagree with exact path of this low. 
One has the low deepening over Lake Superior Wednesday while another 
has the low deepening over Lake Erie. Southeast winds around 25 knots 
are expected through Monday night ahead of the low...then winds 
become west behind it. For speeds went middle of the Road given the 
variability. Could definitely see higher gusts if the low deepens 
closer to the lake. 


Models agree on very strong winds behind the low Wednesday night 
through Thursday. Have high end gales in the forecast and some 
guidance members suggest low end storm force gusts may be possible. 
Do not have the confidence to go that high just yet...but have high 
confidence in at least gales. The low shifts northeast with winds 
diminishing Thursday night. The next low however moves over the 
Southern Plains Thursday evening.
