NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
214 PM CDT Tuesday Oct 21 2014 


Discussion... 
218 am CDT 


Below average temperatures the next couple of days will gradually 
give way to a bout of Indian Summer over the weekend. 


Water vapor imagery shows an amplifying upper trough over the 
eastern Continental U.S. This morning with last evening's upper air analysis 
showing a pocket of sub-freezing 850mb temperatures advecting south into 
the western Great Lakes region. The chilly air moving over the 
relatively milder lake water is currently resulting in a marginal 
lake effect shower set-up with scattered light showers or sprinkles 
showing up over southern lm into northwest in. Low level flow will veer to 
more northeasterly direction today and send some of the lake effect 
cloudiness and potentially sprinkles/light showers into extreme NE 
Illinois this morning. Relatively low inversion heights and somewhat weak 
instability make the chances of measurable precipitation low and have kept 
probability of precipitation in the lower end of the chance category. Cloudiness should be 
most prevalent today near the lake with better increasingly sunny 
skies well inland. Cloud cover should keep highs struggling into the 
lower 50s in NE Illinois while middle or even upper 50s are possible out 
toward Mendota and far southwestern County Warning Area where more sun can be 
expected. 


Low confidence in the extent of lake cloudiness tonight...which 
would play a role in low temperatures. More clouds near the lake would 
result in lows a couple degrees warmer than currently forecast and 
vice versa if mainly clear. Sunny skies are expected Wednesday as 
transient upper ridge builds into the area between departing deep 
upper trough/low and the next strong northern stream shortwave 
slated to arrive in our area later Thursday. Not looking for much of 
a chance of substantial warming Wednesday with a still somewhat cool 
easterly low level flow and only weak low level warm air advection. 


By Thursday shower chances will be on the increase as sharp northern 
stream trough tracks southeast into the western lakes. Lack of 
return flow should result in limited moisture for the system...but 
fairly strong forcing should allow for a period of showers across 
the County Warning Area Thursday afternoon or evening. Not much cooling behind this 
system Friday...then a fast moving weak Canadian cold front should 
bring a brief cool down Saturday before more substantial warm air 
advection Sunday into Monday likely sends temperatures near if not 
into the 70s across the County Warning Area. Medium range models do show a 
progressive long wave trough moving across the Continental U.S. By early next 
week with cold front likely to arrive later Monday or Tuesday 
bringing an end to our brief but potentially impressive warm up.

//Ord and mdw concerns...updated 18z... 


* north/northeast winds 10-14 knots and gusty through early evening. 


* MVFR ceilings possible through afternoon. 


Rodriguez 


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


Despite high pressure building across the region today...ceilings 
have still developed while lake effect cloud cover continues to 
move overhead. These both will scatter/diminish through this 
evening as this high builds across the terminals. Before this 
occurs...periods of high end MVFR ceilings will still be possible. 
Then expect dry and mostly clear skies through the rest of the 
forecast period. Northeast winds/gusts will prevail this afternoon 
before diminishing later this evening...and then remain more 
easterly and under 10 knots early Wednesday morning through the rest 
of the forecast period. 


Rodriguez 


//Ord and mdw confidence...updated 18z... 


* high confidence with wind speed/direction. 


* Medium confidence with MVFR ceilings...medium confidence of 
duration.

* Sunday...dry/VFR. South winds. 
* Monday...slight chance of rain showers. Gusty southwest winds.

Marine... 


215 PM...low pressure over western New York will merge with another 
low over near the Delaware-Maryland-Virginia area tonight...and rapidly deepen 
Wednesday night and Thursday just south of Cape Cod. This low will 
then track northeast to Nova Scotia by Saturday morning. 
Meanwhile...high pressure centered over the southern tip of James 
Bay...with high pressure ridging extending through the middle 
Mississippi Valley...will slowly build east. The brisk 
northeasterly winds currently over the lake will diminish and 
become light and variable late tonight and early Wednesday as the 
ridge axis crosses the lake. While winds should drop below Small 
Craft Advisory levels during the afternoon and early this 
evening...residual wave action will be slower to dampen and still 
expect that waves will remain...above Small Craft Advisory levels 
through much of the night. As the ridge moves to the east of the 
lake Wednesday night...a trough of low pressure will cross the 
Central Plains...reaching the upper Mississippi Valley by Thursday 
morning. This will set up a strengthening southerly gradient over 
the lake with winds increasing to around 20-25kt Thursday afternoon. 
Winds will remain southerly until an associated weak cold front 
pushes across the lake Thursday night.
