NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1008 am CST Sat Nov 22 2014 


Update... 


917 am...morning update...temperatures have warmed into the upper 
30s and lower 40s with the threat of freezing rain over and let 
advisory expire at 9 am. 


Focus now shifts to the potential for dense fog across the far 
northern and northwest portions of the County Warning Area today and tonight. 
Visibilities currently between 1/2sm and 2sm. Not expecting much 
improvement in these areas today so added fog to the forecast... 
generally north of I-80 but confidence regarding how soon dense 
fog may become prevailing and then how long it will last is still 
low. But a dense fog advisory for portions of the northern County Warning Area may 
be needed later today or this evening. Cms 


&& 


Short term... 
315 am CST 


Through tonight... 


The primary concerns with the forecast center on freezing rain 
threat early this morning...then rain potential and amounts through 
the rest of the weekend. 


An area of showers is moving quickly northeast over the immediate 
region as of 315 am. This is within strengthening forcing from a 
short wave trough...and this greater lift is coincident on the nose 
of a 45 knots low-level jet per VAD wind profilers. Overall much of 
this forcing and modest shower activity will continue to shift east 
through sunrise. Steadily rising temperatures had leveled off some 
very early this morning with the heavier precipitation intensity...although 
a slow increase should restart prior to daybreak and persist through 
today as warm advection wins out. Temperatures of 31 to 33 as of 
315 am mainly remained in the northern forecast area...including 
Rockford and the North Chicago metropolitan...and parts of Northwest 
Indiana including Valparaiso. Pavement temperatures from a handful 
of sources varied some...but for the most part were above freezing 
in Chicago and southward from there. So will continue advisory as 
is for now and make a reassessment just prior to 6 am to see if 
any parts need to continue to 9 am. 


While much of the modest precipitation should shift eastward early this 
morning...broad ascent in the middle-levels will remain with an upper 
speed maximum moving overhead. This probably will be enough for 
scattered/intermittent showers especially through early afternoon. 
In the lower-levels...high dew point air will continue to be 
advected northward establishing the low clouds. Isentropic Omega 
within these lowest levels looks to support areas of drizzle...and 
already seeing indications of this near the dvn rda. So continue 
areas of drizzle wording. Temperatures will be the warmest they have 
been since late on the night of November 10th...with 40s expected 
areawide and even 50 tagged south of Interstate 80 in some 
locations. Tonight temperatures should basically hold steady and 
maybe even rise some. If temperatures are able to drop a few 
degrees...the threat for fog becomes higher...although forecast 
soundings generally do not look to support anything dense given 
the already present low cloud deck. 


Rain should begin to develop within greater moisture advection and 
convergence across central Illinois later tonight and spread 
northward into the forecast area. Greater intensity looks to be 
seen beyond tonight into Sunday. 


Mtf 


&& 


Long term... 
315 am CST 


Sunday Onward... 


Sunday the region will remain in a broad warm air advection regime 
ahead of a pair of troughs approaching from the west. Broad deep 
southerly flow will continue to usher warmer and increasingly more 
moist air into the region. Broad isentropic ascent will continue to 
support at least some occasional showers or drizzle early before building 
into a steadier/heavier rain later in the day as the strong southern 
stream shortwave begins lifting northeast into the region. If early 
portion of the day isnt too wet/showery then highs could reach well 
into the 50s...especially southern County Warning Area as guidance is focusing the 
better forcing north early. 


The northern and southern streak shortwaves are still prognosticated to 
begin phasing over the western Great Lakes region Sunday night into 
Monday. Guidance continues to suggest that an impressively moist air 
mass will be transported north into the region Sunday into Sunday. 
Given the magnitude of forcing and ample moisture with precipitable waters  nearing 
2 Standard deviations above average some healthy rainfall totals 
look likely...with amounts Sunday into Sunday night probably ending 
up close to an inch. Long duration of the precipitation should result in 
little more than maybe some minor ponding of water in low spots. Rfc 
contingency forecasts do suggest some respectable rises on area 
rivers...though if current quantitative precipitation forecast verifies rivers will remain below 
flood stage. 


As northern and southern stream systems phase guidance is in 
agreement that the surface low will rapidly...and potentially 
explosively if the GFS verifies. There is a fairly large spread in 
model guidance with respect to just how deep the low gets Monday afternoon with 
the GFS and several of its ensemble members in the between 961 and 
966mb...while the European model (ecmwf) is a still impressive but less extreme 979. 
Lack of strong high pressure in the wake of this system will 
mitigate the magnitude of the winds some...but latest guidance has 
trended stronger with winds again Monday. Still possible there will 
be some waffling in guidance for the Monday time range as models 
often struggle with phasing systems...but have followed the trend 
from the day shift of stronger winds Monday with gusts of 35-40 miles per hour 
possible. If the more extreme GFS model Camp verifies then gusts 
could near advisory criteria Monday...a trend Worth watching the 
next couple days. 


Warm conveyor belt precipitation should get shunted north of the area later 
Sunday night...however models suggest that deformation precipitation could 
potentially wrap as far south as our County Warning Area Monday...especially 
northern County Warning Area. Colder air will come flooding in on the strong 
westerly winds meaning any defo precipitation that does fall would 
transition to snow/snow showers Monday morning. Far too soon to have 
much confidence in any potential accums...but better threat of snow 
accums looks to remain north of the area with accums...if 
any...probably on the light side in our area. 


Stratus deck likely gets locked in Monday night tempering the low 
temperatures a bit but magnitude of the cold air advection should still 
allow 20s across the area. Cloud cover may stick around into a good 
chunk of the day Tuesday as The Heart of the cold air mass traverses 
the area which looks to result in very little temperature recovery from 
overnight lows Tuesday morning. 


Brief and somewhat muted shot of warm air advection Tuesday night 
into Wednesday should occur ahead of a clipper system...potentially 
bringing some light snow to the area Wednesday. Medium range 
guidance varies with respect to the track of this system so 
maintaining probability of precipitation in the lower end of the chance spectrum for now. 
Appears likely that another blast of unseasonably cold air will 
follow this clipper in time for Thanksgiving and the start of the 
long Holiday weekend with highs once again heading back down into 
the 20s.

//Ord and mdw concerns...updated 16z... 


* IFR ceilings likely through the day with temporary LIFR 
possible...namely this morning and tonight. 


* IFR visibility in drizzle this morning and potentially lasting 
into this afternoon. 


* Low-level wind shear tonight. 


* Near due south winds Sunday morning. 


* Rain Sunday morning and continued IFR conditions. 


Beachler 


//discussion...updated 14z... 


Temperatures have risen above freezing...with all precipitation 
now falling as drizzle to light rain. Abundant warm/moist air 
continues to feed north across still cold ground...and will likely 
keep visibilities reduced through the day along with lower ceilings. Could 
see IFR conds linger through the entire day. 


Beachler 


Previous discussion updated 12z... 


Widespread IFR ceilings have overspread the region as moist air 
continues to stream back northward. Within that are areas of 
drizzle and IFR visibility which should continue through early 
afternoon and possibly even longer. The threat for freezing 
precipitation continues...but will slowly diminish. Rfd is the 
most likely area taf site to experience any of this beyond 
12z...but should be done by 14z or 15z. 


The IFR ceilings may improve this afternoon but are still expected to 
remain in the IFR category...and upstream observations are 
supporting this. Tonight the pattern favors ceilings to ease their way 
back down. Drizzle will be possible tonight with rain likely late 
and chances increasing into Sunday morning. 


Winds will be from the south-southwest through this evening and 
then turn more toward the due south overnight into Sunday morning. 
Once again tonight a low-level jet around 2000 feet will support 
low-level wind shear near the inversion height. 


//Ord and mdw confidence...updated 16z... 


* high in IFR ceilings. 


* High in drizzle occurring this morning and medium after. High in 
IFR visibility at times this morning but low on what visibility 
will be this afternoon. 


* Medium-high in low-level wind shear tonight. 


* High in IFR conditions tonight into Sunday morning. Low on 
specific rain timing and visibility within rain.

Marine... 
325 am CST 


An active pattern over the lake is expected to continue through the 
upcoming week. The southwest gales seen over the lake early this 
morning will diminish by middle-late morning as the pressure gradient 
somewhat diminishes. Small Craft Advisory criteria winds will 
continue though across the Illinois and in nearshores a good part of 
the day. It does look like wind speeds will diminish to more 15-25 
knots for the evening and then re-increase overnight where another 
advisory may be needed. 


Moderately strong southerly flow will continue Sunday in advance of 
the complex low pressure system organizing to our west. By Sunday 
night...low pressure tracking east from the northern plains will 
begin to merge with low pressure tracking northeast from the 
Southern Plains. Models suggest this phasing of the two lows will 
take place very near Lake Michigan Sunday night with a brief period 
of lighter winds near the center of the developing storm system. The 
low is forecast to continue to rapidly intensify as it moves north 
Monday allowing for westerly gales to develop on the lake in its 
wake Monday. While model agree in the general idea of a strong low 
north of Lake Superior by midday Monday...they vary considerably on 
how strong the low will be ranging from 28.5 inches to around 29.0 
inches. If the stronger solutions were to verify then a period of 
storm force west winds could occur Monday...despite the lack of any 
strong high pressure moving in behind the storm. If the weaker 
solutions pan out then lower end gales would still likely occur 
Monday. It is likely that a gale watch will be issued for the 
Monday/Monday night time frame later today. Winds will ease Tuesday 
and back to southerly Tuesday night into Wednesday ahead of a 
clipper before another shot of strong and possibly gale force north 
or northwest winds develop Thursday-ish time frame.
