NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1151 PM CST Friday Feb 27 2015 


Short term... 
157 PM CST 


Through tonight... 


Quiet conditions to prevail this afternoon into tonight as high 
pressure dominates the region. Sheared out shortwave will shift 
east through the region tonight...while upstream energy over the 
Central Plains lifts east/northeast through the middle Mississippi 
Valley. This will help provide an increase in middle/high level cloud 
cover tonight...mainly across the southeastern half of the County Warning Area. 
This moisture will remain fairly progressive with the thicker 
moisture likely exiting by early Saturday morning...but with 
partly cloudy to possibly cloudier skies for a time tonight. Made 
minor changes to forecast lows tonight with subzero temperatures likely 
once again. However...dont feel they will be as cold as this 
morning but do think some places could approach 10 below. Winds 
should rapidly drop off this evening and although wind chills will 
fall to around 15 below zero once again tonight...wont be low 
enough for any headlines at this time.

Long term... 
309 PM CST 


Main concerns are with accumulating snow Saturday night through 
Sunday and then a messy...stronger storm system Monday night into 
Wednesday. Hydro issues are possible on Tuesday for at least a 
portion of the County Warning Area. 


Saturday... 


Day will start out quiet and cold with high pressure ridge axis 
overhead. After earlier middle/high clouds in morning pass to east... 
clouds will then increase in the afternoon as isentropic ascent 
begins in earnest. A lead middle level wave in broad west-southwest flow 
at 500 mb could generate some light snow in late afternoon in the 
far southwest County Warning Area...which I included slight probability of precipitation for. High temperatures 
should reach the Lower-Middle 20s thanks to strong nearly March sun and 
warm advection aloft...though a few typically cold spots could be 
held in the upper teens. 


Saturday night through Sunday... 


Guidance is in good agreement in the synoptic pattern of broad 
longer duration isentropic ascent...but there are differences in the 
details...including timing and where cutoff of accumulating snow is 
in the region. There was a subtle trend southward on GFS/European model (ecmwf) with 
12z runs...as well as gefs ensemble mean. Focus remains on 
southern/southeast County Warning Area with best accums by late Sunday. 


Lead wave could bring some light snow or flurries Saturday 
evening...especially southern County Warning Area...with little if any accumulation. 
Timing differences creep in after midnight...but did hedge during 
this period toward slightly faster European model (ecmwf) because forcing for snow 
mainly south of I-80 can be implied by continued warm advection 
which should enable column to saturate. 1 to 2 inches of 
accumulation are possible mainly south of Illinois and Kankakee rivers by 
daybreak Sunday. 


Have some concern on Sunday with how sharp northern cutoff of precipitation 
will be. Did not make big changes to previous forecast probability of precipitation...but 
lowered snow amounts in northern tier of counties to 1 to 2 
inches...which could be generous. Warm air advection/isentropic ascent pattern will 
bring a moist air mass to the southern County Warning Area...with precipitable water values near or 
just over .7 inches. Decent moisture...with roughly half inch 
precipitable waters ...should make it up to Chicago area. Forecast soundings 
indicate decent middle level lapse rates as well in the southern 
County Warning Area...and tightening thermal gradient should yield steady light to 
moderate snowfall rates. Temperatures near or slightly over 30 
degrees will bring snow ratios down closer to average and high March 
sun angle may make it tough for snow to accumulate readily on well 
treated/heavily traveled roadways. 


Overall...snow amounts by late Sunday for the remainder of the County Warning Area 
look to fall into 1 to 3 inch/locally 4 inch range along I-88/I-90 
corridor...2 to 4 inches near and a bit south of I-80 and 4 to 6 
inches south of the Illinois and Kankakee rivers. There could be 
localized amounts just over 6 inches in far southeast County Warning Area...but 
longer duration and light winds should mitigate impacts. Will likely 
need a Winter Weather Advisory for at least part of the County Warning Area south of 
Interstate 80 nonetheless. 


Sunday night and Monday... 


Expansive high pressure will settle over the region Sunday 
night...with skies becoming partly cloudy to mostly clear after 
midnight. Air mass is not all that cold aloft...but strong 
inversion and diminishing winds as high noses in should enable 
chilly temperatures...especially in typical cold spots. Have 
remained conservative with lows for now...but wouldnt be surprised 
if locations such as rpj dip below zero. Deep southwestern trough 
will bring rapid middle level height rises and increasing warm 
advection during the afternoon...but limited mixing through middle 
day under influence of high pressure should limit temperatures to the 
upper 20s to around 30. 


Monday night through Friday... 


Aforementioned deep western trough will result in strong surface 
low moving near or over area on Tuesday. Fairly complex upper 
pattern due to anomalous trough ejecting from southwest and 
differences on guidance on track of surface and middle/upper features 
as well as phasing of all the pieces. Air mass should start out 
cold enough for snow Monday night...but then strong southwest flow 
aloft should quickly warm column above freezing by or during 
Tuesday morning. Wondering if at least northern half of County Warning Area could 
see a front end of accumulating snow...followed by quick 
transition to mix then plain rain everywhere. Unseasonably moist 
air mass advecting in...along with dewpoints possibly approaching 
or exceeding 40 degrees for a time Tuesday into the early evening 
south of I-80...along with steady rain...could result in 
hydrologic issues due to frozen and snow covered ground...and iced 
over rivers. With this system still far out...this period needs 
to be closely monitored for variety of potentially significant 
impacts. Still can see a way out for a more wintry scenario or on 
the other hand...Hydro issues for the entire area if system tracks 
farther north. Colder air will filter back in and change 
lingering precipitation to snow Tuesday night...followed by a blast of 
Arctic air Wednesday into Thursday. Possible large scale pattern 
change to zonal Pacific flow could bring much milder weather by 
next weekend.

//Ord and mdw concerns...updated 06z... 


* period of light snow possible late Saturday evening/overnight. 
MVFR/brief IFR conditions associated with precipitation. 


Ratzer 


//discussion...updated 06z... 


High pressure over the area early this morning will start Saturday 
out with similar quiet conditions as on Friday. Only a few middle- 
level clouds...and those mainly south of the terminals...will be 
present with a weak disturbance moving through largely dry 
atmosphere through mid-day. Moisture will increase from the south 
late in the day...with VFR ceilings developing and lowering to 
4000-5000 feet above ground level by early evening. Model forecast soundings 
indicate deepening middle-low level saturation developing middle-late 
evening as an upper level disturbance tracks across the region. 
Guidance indicates a period of light snow beginning 03z-ish and 
and lingering past midnight before a lull develops as the middle- 
level wave moves away to the east. Additional periods of light 
snow appear likely beyond end of the current taf period Sunday 
morning- early afternoon...though the best forcing/saturation 
looks to remain to the south of the terminals. 


As for winds...surface high passing south of the terminals early 
this morning resulting in southwest winds less than 5 knots backing 
to the south-southeast after sunrise...with speeds generally under 
10 knots though the day. Light southeast winds expected Saturday 
evening.

Marine... 
157 PM CST 


Large high pressure situated just south of the lake this afternoon 
while low pressure is over Hudson Bay. This is allowing for 
generally westerly winds over the lake in the 10 to 20 knots range. 
This high will slide to the east tonight into Saturday...with 
winds becoming more southwest overnight and while winds slightly 
increase to the 15 to 25 knots range for a brief period. A period of 
southerly winds will occur on Saturday and Saturday night with 10 
to 20 knots range increasing back up to the 15 to 25 knots range. 
Generally lighter flow expected over the lake to end the 
weekend...before winds increase once again out of the 
west/northwest Sunday night into Monday.
