NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1248 am CDT Wednesday Jul 30 2014 


Discussion... 
218 PM CDT 


Forecast issues continue to focus on daily diurnal isolated to 
scattered shower/thunderstorm chances...with very gradual warm up in 
temperatures through the forecast period as long wave upper trough 
over eastern North America effectively retrogrades through the end 
of the week before finally weakening and progressing off to the 
northeast by late weekend and early next week. 


Western Great Lakes region remains in western periphery of this 
aforementioned trough...within region of broad cyclonic circulation. 
Series of relatively minor short waves will continue to ripple 
south-southeast through the flow across the area through the 
remainder of the week. GOES water vapor imagery indicates a couple 
of weak ripples passed across the region this morning...with a 
somewhat more robust short wave noted upstream propagating south 
across western Ontario. These systems will tend to modulate 
middle-level temperatures and instability...especially when juxtaposed atop 
afternoon/early evening diurnal warmth. Forecast soundings continue 
to indicate weak/skinny MLCAPES of 200-300 j/kg this afternoon... 
with visible satellite imagery indicating cumulus congestus 
development along weak low level convergence axis from near Rockford 
to the southeast side of Chicago/Northwest Indiana where the lake 
breeze boundary was providing some additional convergence. 
Current weak radar returns expected to continue to slowly grow 
this afternoon through peak instability...resulting in isolated to 
scattered showers and perhaps a few thunderstorms. Waning 
instability after sunset this evening will allow a decrease in 
coverage. Similar trend expected tomorrow...though Ontario short 
wave looks to move across area during the morning...as opposed to 
during period of better instability later in the day. This may 
favor southeast parts of the County Warning Area where forcing will decrease 
last...while daytime instability develops. These diurnal 
showers/isolated thunderstorms...tied to convergence zones as is 
the case today...will continue in similar fashion Thursday as 
well. Obviously...not all areas will see precipitation and there will be 
many dry hours even in places that do. By Friday...additional 
short wave energy will drop into the western portion of the trough 
from the northern plains and will effectively retrograde the long 
wave trough axis westward into the western lakes and 
Mississippi/lower Ohio Valley area. Large scale height falls will 
lead to slightly cooler middle-level temperatures which may support greater 
coverage in showers/thunderstorms Friday and Saturday before the 
trough axis becomes more progressive and moves off to the east 
Saturday night and Sunday. Thus have maintained somewhat higher 
chance probability of precipitation with a greater aerial coverage for those daytime 
periods. 


Surface high pressure then builds across the area Sunday...before 
drifting to the southeast Monday as another short wave trough 
approaches in northwest flow aloft. This middle-level wave is 
accompanied by a surface low and cold front...which returns the 
shower/thunderstorm threat for Monday/Tuesday of next week. 


As for temperatures...middle and upper 70s being reached this afternoon with 
considerable sunshine. Middle-level temperatures continue to moderate very 
slowly through the period...with to slowly warming from upper 70s to 
around 80 to lower 80s outside of lake breeze and showers into the 
weekend. Cold frontal passage late Monday will allow subtle 
cool-down from the north by Tuesday.

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


* lake breeze expected with NE winds at 10 knots behind it. 


* Scattered rain showers this afternoon and evening. A few thunderstorms and rain possible.

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


Showers have pushed south of the terminals but today is looking 
very similar to yesterday. A lake breeze is expected along with a 
weaker upper level wave. The lake breeze will provide enough 
forcing for scattered rain showers this afternoon and evening...but thinking we will 
see less activity than yesterday. A few thunderstorms are also 
expected as well but they should be isolated enough to leave out 
of the taf for now. 


Winds become NE around 10 knots behind the lake breeze at mdw and 
Ord....and north-northeast at gyy. Have high confidence that the lake breeze 
will make it through mdw and gyy and medium-high confidence about 
Ord. Winds slowly return to the SW in the evening with continued 
VFR conditions.

210 PM CDT 


High pressure in the northern and Central Plains is expected to 
weaken some over the coming days but generally remain stationary for 
most of the week as an upper level low pressure systems remains 
parked over James Bay through Saturday. In this pattern weak low 
pressure systems will Glide southeast down the lake at times...with 
the first expected later tonight into early Wednesday. 


In this stagnant pattern the pressure gradient will remain on the 
lighter side and will promote the development of lake breezes for 
the nearshore waters and variable winds over much of the Open Lake 
and winds generally 15 knots or less. Kmd
