NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1002 PM CDT Friday Oct 24 2014 


Discussion... 
947 PM CDT 


Isolated showers are moving through this evening. Most areas will 
remain dry...and expect showers to be into Northwest Indiana after 
midnight...and east of the area shortly thereafter. 
Otherwise...expect some fog to reform again tonight...with western 
areas favored due to a thinning and lowering of clouds. 


Kmd 


//prev discussion... 
304 PM CDT 


This evening and tonight... 
broad surface high stretches from the lower Mississippi Valley into 
the upper Ohio Valley and eastern Great Lakes this afternoon while 
low pressure lies over Ontario with a cold front stretching into the 
Central Plains. A narrow ribbon of moisture is analyzed out ahead of 
the cold front with 60 degree dewpoints stretching north into 
northern Iowa this afternoon...and just off the deck a corridor of 
low/middle level Theta-E advection is driving at least a few very weak 
radar returns over far southeast Minnesota and NE Iowa. Rap/hrrr guidance shows this 
area persisting across northern Illinois this evening with the 
chance for a few showers. Given the very sparse coverage so far 
upstream and the dry soundings/limited duration of forcing...not 
biting off on precipitation moving across the forecast area...but will 
maintain some low end slight chance probability of precipitation since there are some 
ingredients in place. 


Saturday through Sunday... 
weak front will pass across the area early on Saturday with dry air 
filtering back into the region as an upper ridge builds over the 
area and subsidence sets in overhead. Expect dew points to mix out 
nicely tomorrow afternoon...especially in north central Illinois 
where dew points may drop into the low to middle 30s. The dry 
conditions should allow for a nice response from diabatic heating 
which will result in temperatures a few degrees warmer tomorrow. 
Meanwhile...surface high will build from the northern plains 
Saturday directly overhead early Tuesday morning which will allow 
favorable radiational cooling Sunday morning with lows dipping into 
the 30s in outlying areas and some of the typical cold spots. 
Elsewhere expect low 40s with downtown Chicago staying propped up in 
the middle 40s. Temperatures may be a bit tricky Sunday with warm 
advection aloft increasing through the day on the backside of the 
surface high. A cool starting point and increasing cloud cover 
through the day will keep highs only into the 60s Sunday afternoon. 


Sunday night through Monday... 
upper ridge begins to buckle Sunday night into Monday as shortwave 
trough digs from the Pacific northwest into the Central Plains. Broad surface 
low pressure over the plains will shift east towards the Midwest 
early Monday with southwest flow increasing out ahead and a corridor 
of moderate to strong middle level Theta-E advection lifting across the 
local forecast area on the nose of a 40kt or so low level jet. 
Column is fairly dry out ahead of the baroclinic zone but a narrow 
layer of saturation could tap into some modest instability rooted 
between h7-h9. This does point to some chances for thunderstorms 
though chances are better to our north where the MUCAPE aligns 
better with the forcing from the low level jet. Expect lowering 
clouds in the predawn hours as the surface warm front approaches. 
The middle levels dry out again and the moisture is fairly shallow so 
any additional precipitation early on Monday may just be drizzle. Surface 
warm front lifts across the area middle morning Monday and expect dry 
conditions once in the warm sector with low cloud cover eventually 
scattering. 850 mb temperatures warm to 15-16c with 17c being the 99th 
percentile of upper air climatology for the end of October. Surface highs 
will be well above normal...possibly pushing 20f above 
normal...though the record high should be safe. Leaned heavily on 
ec/ecbc for afternoon highs Monday forecasting middle 70s...with upper 
70s south of I-80. The warmer conditions will be accompanied by 
stronger winds however with southwest winds gusting 20 to 25 miles per hour and 
possibly 30 miles per hour at times. 


Tuesday through Friday... 
models are indicating a strong low pressure system will begin to 
develop over the region early next week with a cold front sweeping 
across the are Monday night into early Tuesday bringing chances for 
shower and thunderstorms. The low really begins to deepen in earnest 
as it lifts across the Great Lakes into Canada Tuesday into 
Wednesday with driving polar air south into the Canadian prairies 
and a cold polar high grazing the local area late next week. Details 
still murky this far out but does appear we could be in for a big 
cool down late next week in time for Halloween if current GFS/European model (ecmwf) 
runs pan out.

//Ord and mdw concerns...updated 03z... 


* lowering ceilings late evening/overnight...MVFR probable with 
IFR/LIFR a low possibility. 


* MVFR visibility possible overnight. 


* Improving ceiling/visible Saturday morning with breezy west-northwest 
winds. 


Ratzer 


//discussion...updated 03z... 


IFR/LIFR ceilings and visible expanding across parts of central and 
eastern Iowa this evening...expected to spread into parts of 
northwest and western/central Illinois late tonight. Latest model 
guidance continues to indicate potential for low ceilings/visible mainly 
west and southwest of the Chicago terminals. Have indicated a 
period of IFR conditions at rfd during the early Saturday morning 
period...with lower MVFR conditions likely farther east across 
Ord/mdw/gyy/dpa. 


Ratzer 


Previous discussion from 00z... 


Subtle surface low pressure wave was over eastern Iowa early this 
evening...and will move east across the terminals overnight. An 
area of IFR/LIFR ceilings and fog was located just ahead of this wave 
across eastern Iowa/southwest Minnesota...and is expected to 
advance into parts of southwest Wisconsin and western Illinois 
overnight...as light south-southwest winds continue to advect low 
level moisture ahead of the wave. A faster moving cold front with 
a strong push of drier air will overtake the weaker wave 
overnight. A few sprinkles will be possible later this evening as 
an associated upper level disturbance enhances lift...though these 
should be very light and fairly isolated. 


Low end VFR and MVFR ceilings are expected to spread east as far as 
the Chicago terminals during the late evening/overnight hours... 
though confidence is low that the lower IFR/LIFR ceilings over Iowa 
will make it this far east as the low level moist axis gets 
pinched off by the faster cold front. The second front will clear 
the terminals Saturday morning...with much drier air scouring out 
any low clouds that do form overnight. 


South-southwest winds less than 10 knots this evening will shift to 
the west with the frontal passage pre-dawn Saturday. West- 
northwest winds around 10 knots will become breezy with gusts near 20 
knots later Saturday afternoon. 


Ratzer 


//Ord and mdw confidence...updated 00z... 


* high confidence ceilings lowering to lower end VFR later this 
evening...medium confidence in MVFR ceilings overnight. Low 
confidence in ceilings IFR/LIFR developing. 


* Medium confidence in MVFR ceilings overnight. 


* High confidence that -shra coverage will be low late this 
evening. 


* High confidence in improvement to VFR and west winds Saturday. 


Ratzer 


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


Sunday...VFR. Slight chance rain showers/thunderstorms and rain Sunday night. Southeast winds. 


Monday...VFR by day...shra/tsra likely Monday night. Breezy 
south winds. 


Tuesday...chance shra/tsra. MVFR possible. Southwest-west winds. 


Wednesday and Thursday...VFR. West-southwest winds.

High pressure is slowly pushing east with light southwest winds over 
the Lake. A weak lake breeze has turned winds onshore over Lake 
County Illinois. Southwest winds increase to 20-25 knots this evening with 
occasional 30 knots gusts possible over the north half of the lake overnight. 
Winds turn west 20-25 knots behind the front and slowly become northwest Saturday 
night. Points north of Wilmette Harbor may see occasional gusts to 25 knots 
tomorrow...but thinking sustained small craft conditions will not be 
met. Winds diminish as a high moves over the lake Sunday. Winds 
become south behind the low and then turn southeast and increase to 20-25 
knots as the next low approaches Sunday night. There is still a lot of 
variability in the strength and path of the next low so confidence 
is low in the exact wind speeds. One model does feature westerly 
gales on the backside of the low Tuesday night...but do not have 
enough confidence to go that high in the forecast just yet. High 
pressure moves in middle next week and winds slowly diminish Wednesday. 


Still thinking there is a marginal chance for small craft conditions 
to be met Monday night through Tuesday...but will hold off on 
headlines for now.
