NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
546 PM CST Friday Feb 5 2016 


Short term... 
232 PM CST 


Tonight through Saturday... 


Low clouds continue to scatter-out from northwest to southeast 
this afternoon as weak surface high pressure moves into the region 
in the wake of this mornings weak cold front. High clouds were 
already beginning to spread across the area from the west...ahead 
of the next disturbance over the plains. Expect that temperatures will 
fall off into the 20s with sunset...then hold nearly steady 
overnight as clouds thicken. Guidance in close agreement with 
temperatures and did not stray much from met/mav blend. 


Another weak clipper system will move across the area tonight 
into Saturday morning...kicking a weak short wave over the middle- 
Missouri Valley northeast across the region ahead of it tonight. 
Upstream 12z radiosonde observations from this morning depict fairly dry air below 
about 650 mb and model soundings and time-height depictions 
indicate that lower levels may struggle to with generally weak 
forcing for ascent. Regional radar mosaic and surface observation do 
indicate light snow occurring across western Iowa at this 
time...though models erode this precipitation with time as it tries to 
spread east. Thus while middle/high clouds will thicken this 
evening...no guidance produces measurable precipitation from the 
approaching system and it appears that anything more than a few 
flurries is unlikely. Timing for flurries appears to be mainly 
after midnight tonight through early Saturday morning. 


Middle-level trough axis moves off to the east of the forecast area 
Saturday afternoon...with associated surface trough washing out 
across the County Warning Area and becoming indistinct. T-sects indicate skies 
will become partly sunny especially across the southern parts of 
the County Warning Area. Modest southwest winds maintain warm advection through 
the day and 925-950 mb temperatures support afternoon highs in the middle- 
upper 30s far north...and in the lower 40s along and south of the 
I-80 corridor. Preferred the slightly warmer mav guidance for 
Saturday maximum temperatures.

Long term... 
239 PM CST 


Sunday night through Friday... 


Saturday night through Sunday... 
relatively quiet for Sat night as a southern stream middle-level trough 
slowly slides east...with the northern stream in transition. 
Upstream of the Great Lakes region will be weak height rises which 
will likely delay precipitation arrival for sun due to greater subsidence 
in the lower levels. By daybreak sun a shortwave will be sliding 
south from central Canada into the northern plains and quickly slide 
east by midday sun to the upper Midwest...with a surface wave producing 
a Lee-side frontal boundary. Guidance is enhancing this boundary as 
it clips northern Illinois midday sun...indicating steady moistening in 
from the top/down and possibly bringing some light precipitation to the 
forecast area. Fortunately a push of warmer air from the south 
through the morning/midday sun will lift surface temperatures into the upper 
30s to possibly the middle 40s across the Kankakee valley. So any light 
precipitation that falls will be as light rain at the onset. 


With colder air steadily advecting south as the vorticity maximum arrives 
over central wisc...lapse rates will steepen and should begin to 
bring a light rain/snow mix in the evening hours. At this time quantitative precipitation forecast 
remains very low...and any light snow that were to fall would 
struggle to accumulate at the onset. However as cold air continues 
to advect across the region late sun...perhaps a dusting will occur 
by daybreak Monday for areas north of I-80. 


Monday through Thursday... middle-level vorticity maximum will be stubborn to 
depart the region as it sags south across northern Illinois Monday...and 
eventually slides east early Tuesday morning. Surface gradient will begin to 
diminish as the low slides overhead early Monday...but once the 
shortwave pushes east the gradient returns and winds increase from 
the northwest. 850mb thermal trough of -9 to -12 degree c slides 
overhead from the northwest and should keep surface temperatures in the 30s 
from the considerable solar shielding Monday...then even colder air 
arrives aloft Tuesday with temperatures struggling to warm beyond the 20s for 
highs. Flow will be turning northerly along the back side of the 
departing trough Tuesday...which would allow for some lake effect precipitation 
to develop and likely keep considerable cloudiness for areas 
adjacent to Lake Michigan...especially Northwest Indiana. 


Ensembles continue to feature a high confidence in a high amplitude 
500mb ridge along the western Continental U.S. Extending north into western 
northwest Canada...with the downstream trough lingering across the 
Great Lakes region. Through time it does appear the trough will 
expand as the ridge over the western Atlantic begins to shift 
east...however this will keep an unseasonably cool air over the 
Great Lakes region through the bulk of the extended periods with 
periodic chances for flurries/light snow.

Aviation... 
for the 00z tafs... 


Main forecast concerns are with a low probability of MVFR 
ceilings and flurries late tonight into early Saturday morning. 
However...have excluded mention of either in the tafs due to low 
confidence. 


Middle level cloud cover continues to move across the terminals and 
am expecting VFR ceilings this evening. MVFR ceilings just to the 
south/southeast of the terminals will likely remain to the south. 
However...as the current high in place shifts to the 
east...additional upstream lower ceilings could push towards the 
terminals. Once again...low confidence with this solution and have 
excluded any mention. An upstream middle level disturbance could 
provide some flurries tonight but with little if any impacts 
expected at this time. Westerly winds will become southwest this 
evening into Saturday...while VFR conditions continue.

&& 


Marine... 
104 PM CST 


Marine forecast concerns focus on a couple periods of stronger 
flow. The first of these comes tonight into Saturday morning 
across northern parts of the lake...as west-southwest winds 
increase to 25-30 knots in response to an area of low pressure 
passing to the north of Lake Superior. The gradient will ease a 
bit by Saturday afternoon as a weak cold front sags across the 
northern lakes. Deeper low pressure will track southeast along 
this boundary Saturday night... resulting in winds backing more 
southerly and picking up to 20-25 knots. The low is expected to move 
across Lake Michigan on Monday with winds decreasing as the 
gradient again weakens near the low center. The low will move 
slowly off to the east-southeast Monday night...while high 
pressure builds across the Canadian prairies and northern plains 
and causes the gradient to strengthen again. North-northwest winds 
are expected to increase to 30 knots after midnight Monday night and 
continue through Tuesday. Some model forecasts support marginal 
gales during this period.
