NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1033 PM CDT Monday Jul 6 2015 


Update... 
813 PM CDT 


The storm threat continues to diminish though periods of moderate 
to briefly heavy rain with some embedded thunder are still 
expected through early overnight...with the most 
frequent/prolonged activity likely south of I-80. While plenty of 
MUCAPE aloft of 1500-2500 j/kg...most storm clusters have 
struggled to sustain likely due to very limited effective shear 
in the absence of any pronounced forcing mechanism. In 
addition...while the low-level jet is strengthening...moisture 
transport is likely being robbed by significant storm coverage to 
our southwest. Will still need to monitor for locally heavy 
rainfall as a high precipitable water air mass /1.59 inches on 00z ilx radiosonde observation/ 
progresses over the area with some locations receiving successive 
batches of rain. 


Have adjusted temporal probability of precipitation to meet latest thinking...with still 
likely probability of precipitation for most locations at some point during the 
evening and early overnight...but took down the thunder 
wording/coverage significantly. 


Mtf 


&& 


Short term... 
252 PM CDT 


Through tonight... 


A line of showers is moving through northeast Illinois with additional 
showers and storms over southern and eastern Iowa. The line of 
showers with a few embedded thunderstorms will continue east and may 
weaken further as the outflow boundary has started to separate 
itself from the line of showers. Heavy rain...a few gusts of 
wind...and a few funnel clouds have been reported with this line of 
showers. The Funnel clouds are forming as boundaries intersect...but 
the funnels are not located under any updrafts so tornadoes are not 
expected. 


Temperatures are falling into the 70s behind the line of showers and 
with the thick cloud cover...recovery is very slow at best. 
Therefore locations over northwest Illinois actually saw their high temperatures 
early this morning as they will stay in the 70s. Have falling temperatures 
also across Northwest Indiana as the storms roll through...but if the line 
falls apart...temperatures will likely stay in the low to middle 80s. 


The cold front stretches across northwest WI through southern Minnesota and 
northwest Iowa and is prognosticated to swing through northern Illinois and Northwest Indiana 
overnight. Another round of showers are expected ahead of the cold 
front...but not expecting much if any severe weather. The latest 
rap analysis shows 500-2000 j/kg of cape behind the line of storms 
over north central Illinois...with the values decreasing as you get closer 
to the Mississippi River. Shear values are also around zero...so 
organized storms are not expected. Expecting the next round of 
showers and storms to move into northwest Illinois after 5pm CDT and 
continue across northern Illinois and Northwest Indiana through the night. This 
round will also have lightning...heavy rain...and probably some 
gusty winds...but widespread severe weather is not expected. 


Given the lower than expected high temperatures today...lowered low temperatures 
tonight as well. Dew points will remain in the middle 60s to around 70 
so low temperatures should stick pretty close to the dew points. Expecting 
lows to vary from the middle 60s around rfd to around 70 in Northwest Indiana. 


Jee 


&& 


Long term... 
325 PM CDT 


Tuesday through Monday... 


The front will continue shifting south through Tuesday morning 
with northerly winds and cold advection enveloping the area. Such 
as has been the trend with the system...did also speed up the end 
of rain chances on Tuesday. Think shower coverage in the morning 
will be scattered within Post frontal forcing...and any thunder 
likely even more isolated. Stratus is likely to linger longer than 
the rain chances as the cool air collides with the moist boundary 
layer. It is certainly possible clouds stick around for southern 
areas as well as locations near the lake through the afternoon. 
High pressure should keep the area mainly dry into Wednesday 
morning. 


Temperatures both Tuesday and Wednesday look to be well below 
normal with highs primarily in the lower 70s...with middle-upper 60s 
near the Lake Shore. These readings across the forecast area are 
10 to 15 degrees below normal for early July. In-between on 
Tuesday night...any clouds should be confined to the southern County Warning Area 
which will allow northern communications to dip into the 
50s...even lower 50s for outlying locations. 


Beyond...short wave impulses look to be key to rain chances with 
one becoming more consistently targeted on guidance Wednesday 
night. The window of instability return looks limited...so this 
could be mainly just showers especially north of I-80. Each 
successive impulse appears to bring the Theta-E gradient aloft 
more so over the area which warrants storm chances almost daily 
late in the week into the weekend. Temperatures also look to 
rebound back to normal by the weekend.

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


* rain may persist through early Tuesday morning...with a few embedded 
thunderstorms. 


* South winds around 10-14kt steadily turning west/northwest by 
early Tuesday morning. Winds flip northeast and increase with gusts 
to 22kt possible Tuesday midday. 


* MVFR ceilings possible briefly with rain tonight...then more likely 
Tuesday morning. Possible Tuesday morning ceilings could dip to IFR.

//discussion...updated 00z... 


Channel of very warm/moist air continues to feed northeast across 
northeast Illinois/northwest in. Rain and a few thunderstorms continues 
to develop this evening...however expect the coverage of thunder 
to slowly diminish. Rain may increase is coverage and intensity 
later this evening...however some guidance is indicating that as 
the frontal boundary slowly drops southeast overnight...this may 
diminish and result in spotty showers overnight. Clouds will 
remain thick overnight and bases may flirt with MVFR conds 
overnight. As the boundary arrives overhead...MVFR ceilings will 
spread in coverage and could perhaps dip to IFR conds around 
daybreak Tuesday. Winds will be slowly turning northwest to 
north...and guidance continues to indicate by middle-morning Tuesday that 
wind speeds will increase and could become gusty to 20-25kt. 
Clouds will slowly erode Tuesday afternoon...with VFR conds returning. 


Beachler 


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


* high confidence in rain over Ord/mdw...low confidence in when 
rain will end. 


* Low confidence in coverage/timing of thunder overnight. 


* High confidence in wind dir/speed...high in gusts developing Tuesday 
midday. 


* Medium confidence in ceilings...high confidence in ceilings dipping to 
MVFR conds. 


Beachler 


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

Thursday through Sunday...periodic chances for showers and 
thunderstorms.

Marine... 
252 PM CDT 


Wind gusts were not as strong as expected across the nearshore 
waters today as thick cloud cover limited mixing. A line of showers 
that has a history of producing gusts up to 30 knots is moving across 
the nearshore waters so will keep the small craft going through 
00z/7pm CDT to account for shower related gusts. Winds will pick 
back up tomorrow and a Small Craft Advisory has been issued for 
points south of Chicago from 9am CDT Tuesday through 4am CDT 
Wednesday. Flow will be on shore so wave heights along the Indiana 
shore will grow to 4-7 feet and then come down Tuesday evening and 
night. Winds diminish as high pressure spreads over the lake 
Wednesday morning. Winds will be light and variable over the north 
half of the lake into Wednesday evening while a weak low passes just 
south of the lake Wednesday night. Winds will be northeast then 
north Thursday afternoon. Winds remain less than 10 knots as the high 
slowly shifts east through the end of the week with the next low 
impacting the lake early next week. There will be additional 
periodic chances of thunderstorms Wednesday night and then from 
early Friday morning through early next week.
