NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1106 am CDT Wednesday Jul 29 2015 


Update... 
1106 am CDT 


For morning update... 


Middle-morning surface analysis depicts cold front pushing through the 
eastern portion of the County Warning Area...approximately along or just east of a 
Burns Harbor Indiana to Champaign Illinois line at 1530z. Some patchy 
lower clouds linger within and just behind the frontal zone...with 
surface dew points pooled in the mid-70s...though humidity 
decreasing 75-100 miles behind the front with dew points dropping 
into the middle-upper 50s over northwest Illinois. This drier air mass will 
continue to spread into the forecast area into this afternoon... 
making for more comfortable conditions despite air temperatures still 
expected to rise into the middle-upper 80s under mostly sunny skies and 
breezy northwest winds 15-20 miles per hour. 


Across the far southeast tier of counties where the front will 
continue to push east-southeast into the early afternoon hours... 
there is still the potential for an isolated shower or thunderstorm 
where moist low levels promote destabilization...though have lowered 
probability of precipitation to 20 percent or less into early afternoon then trended dry as 
front clears the area. 


Ratzer 


&& 


Short term... 
332 am CDT 


Through tonight... 


Ongoing T-storm activity over eastern County Warning Area associated with pre 
frontal trough should clear the area prior to sunrise. Attention 
for the morning hours will turn west toward the synoptic front and 
the potential for any shower and possible T-storm activity with 
it. Despite rather paltry appearance of precipitation with front at this 
time...certainly less than guidance would suggest...am still 
concerned that some development could take place give the 
magnitude of moisture and forcing with front. Any scattered showers and 
possible thunder should clear majority of the County Warning Area by noon...but 
some activity could linger or redevelop south of Kankakee River in 
Northwest Indiana early this afternoon. 


In wake of the front dewpoints will begin to tumble...most 
noticeably over northwest half of the County Warning Area through middle afternoon with 
noticeably less humid air arriving in Chicago metropolitan area by middle- 
late afternoon and in Northwest Indiana early this evening. Air mass not 
that much cooler behind the front so highs should once again climb 
well into the 80s to perhaps near 90 if there is enough sunshine. 


Izzi 


&& 


Long term... 
332 am CDT 


Thursday through Tuesday... 


Sunny and very warm weather is on tap for Thursday with 
comfortable humidity levels by late July standards. Friday looks 
to be a Carbon copy of Thursday with perhaps just a few more 
clouds but still a lot of sunshine. Prognosticated 925mb temperatures in the 
low-middle 20s celsius supports highs in the upper 80s to lower 90s 
and given such low dewpoints and ample sunshine have leaned closer 
to warmer guidance both period. 


Weak cold front slides through Friday night and cannot totally 
rule out some isolated convection with it...the fact its coming 
through at diurnally unfavorable time of day and with no return 
moisture work against introducing probability of precipitation at this time. After 
coordination with mkx it was decided to keep probability of precipitation in the 10-15 
percent range in the grids...below mentionable threshold in the 
text forecast for now. A couple of more weak northwest flow front 
are slated to move across the County Warning Area Sunday afternoon and Tuesday 
afternoon...both of which could bring some scattered storms but 
neither looking like big time washouts from widespread rain 
either. For now held onto model consensus lower end chance probability of precipitation 
for both fronts. No significant cool Downs expected with either 
front at this time.

Aviation... 


//Ord and mdw concerns...updated 16z... 


* northwest winds gusting up to 20 knots. 


Jee 


//discussion...updated 12z... 


Showers and some thunderstorms have split the terminals...now 
across southern WI and parts of central Illinois. Little support for 
additional showers or thunderstorms but still a slight chance for 
another few hours...but confidence too low for including in this 
forecast. By late morning...the threat of any precipitation will be east 
of the terminals with dry weather expected for the rest of the 
period. 


Patchy MVFR ceilings have developed across parts of north central Illinois 
and these will be possible at all the terminals through middle morning 
but overall duration should be short...if they occur. 


Westerly winds will turn northwest this morning and increase into 
the 10-15kt range. These winds will then turn back a tad more to 
the west through afternoon but with gusts into the upper teen and 
lower 20kt range expected through sunset...when winds will diminish 
under 10kt. Cms 


//Ord and mdw confidence...updated 16z... 


* high confidence in all forecast elements. 


Jee 


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


* Thursday night through Saturday...dry/VFR. Westerly winds. 
* Sunday and Monday...chance of thunderstorms and rain. Westerly winds. 
* Tuesday...slight chance of thunderstorms and rain. North/northeast winds.

Marine... 


233 am...deep low pressure over Manitoba will move northeast to 
Hudson Bay Thursday as a trailing cold front moves across the lake 
today. Southerly winds 15-25 kts over the northern portion of the 
lake will remain at those speeds but only gradually turn westerly 
by this evening. This low will remain over Hudson Bay through the 
end of the week...while slowly weakening. High pressure will build 
across the Central Plains today and tonight and gradually spread 
into the Ohio Valley Thursday and Friday. This will maintain a 
westerly flow across Lake Michigan with periods of 15-25 kts 
possible into Thursday. The gradient will then relax with speeds 
diminishing. A weak trough/front will move across the lake Friday 
night...briefly turning winds to the northwest before turning back 
to the southwest Saturday. Cms
