NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
403 am CDT Tuesday Mar 31 2015 


Short term... 
338 am CDT 


Through Wednesday... 


Low pressure across the southern tip of Lake Michigan at daybreak 
will continue to race eastward this morning. A trailing cold 
front...partially helped by the cooler air over the lake...will drop 
over the entire forecast area by middle morning. At least temporary 
overcast low clouds are likely in northeast Illinois within the 
marine modified cool sector of the system during this 
morning...possibly even into afternoon. Synoptically the winds 
will want to become more northwest by late morning into 
afternoon...however the speeds will also be diminishing as the 
advection behind the low eases. This should allow for a lake 
breeze to develop...or at least for continued onshore flow...into 
parts of northeast Illinois and especially Northwest Indiana. All 
this leads to some temperature undulations in Lakeside 
counties...with highs forecast in the middle 40s to low-middle 50s from 
near to further from the lake in those counties. If clouds persist 
longer those immediate Lakeside temperatures may end up being in 
the upper 30s. Far outlying areas from the I-39 corridor and 
DeKalb to Kankakee and southwest from there should moderate to 
the upper 50s to lower 60s. 


Increasing upper heights will be seen across the area during the 
day Wednesday. Strengthening southerly flow especially by 
afternoon will bring an impinging low-level thermal nose into the 
area. With 925mb temperatures around 10c this should allow for 
upper 60s to lower or even middle 70s across much of the forecast 
area. One major challenge though is that as pressure falls first 
start advancing in...the winds look a little more backed to the 
southeast near the Illinois shore...and the gradient could be 
light enough to allow a lake breeze to creep inland. This may not 
make much progress inward and probably retreat later in the 
day...but could present a significant difference in temperatures 
for much of the day from what a southwest wind would yield. Have 
leaned toward the lake breeze...albeit not as chilly as it could 
be...and gone more 50s in northeast Illinois within 10-20 miles 
of the shore...but confidence on specifics 36 hours out with this 
phenomena is low.

Long term... 
338 am CDT 


Wednesday night through Monday... 


A northern stream trough will move over the international border of 
the northern plains Wednesday night to the Great Lakes by Thursday 
evening. A sub 990mb low is expected with this system across 
Ontario with moisture advected northward ahead of its cold front. 
The southerly winds will make for a mild night Wednesday night with 
lows in the 50s. Convection is likely to trigger across the Missouri 
River valley into southern Minnesota Wednesday evening and evolve 
east within increasing upper forcing and replenishing moisture 
transport. Showers and likely some thunderstorms should translate 
into our region by Thursday morning. Have continued to focus the 
probability of precipitation temporally...guiding closer to the slower 00z ec and NCEP NAM 
and sref models. 


The morning clouds and showers and storms will make for a challenge 
with temperatures and ability to destabilize or revamp any 
ongoing convection Thursday afternoon...in addition to some 
discrepencies in timing already from guidance. Boundary layer dew 
points are expected to be into the middle-upper 50s using the better 
initialized ec across the current high dew point air of the 
Southern Plains. So if scattering and some re-warming can 
occur...this will likely result in enough instability for 
convection to redevelop near the frontal zone. Given middle-level 
winds of 45-60 knots this could support some organized stronger 
storms...for our area mainly along/south of I-80 given the current 
ec and NAM. 


Have not made any major changes beyond this time period. Friday 
is forecast by guidance to have a short wave...possibly 
strong...translate along the frontal boundary to our south 
resulting in some rain immediately north of its path. But again 
some shifts in this are certainly plausible. The boundary looks 
to return as a warm front later this weekend and the GFS is the 
quickest with this. The more defined this boundary becomes the 
greater the challenge with both temperatures and possibly earlier 
shower/storm chances. Sunday especially could have highs areawide 
in the 60s/lower 70s...or 40s especially in northeast Illinois 
with a more easterly wind.

Aviation... 


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


* wind directions today...with potential for north-northeast 
(350-020 deg) winds early shifting to northwest and then 
possible lake breeze in the afternoon especially at mdw. 


* Potential for lower MVFR/higher end IFR ceilings this morning. 


Rc 


//discussion...updated 09z... 


IFR ceilings are pushing southward in Wisconsin...quickest along the 
southeast Wisconsin shore. A period of lower ceilings is becoming more 
likely for Ord/mdw/gyy and possibly as far west as dpa but how 
low is in question due to dry air mass over the terminals at this 
time. Will go with a low ceiling in the Ord/mdw/gyy tafs and monitor 
observational trends. 


Rc 


..from 06z... 


A clipper low pressure system is centered over southern Wisconsin 
early this morning...with strong pressure falls immediately ahead 
of it resulting in strong southwest winds gusting up to 25 to even 
30 knots over northeast Illinois. Winds will shift to northwest and 
then north behind the low and lake influence could bring a brief 
period of north-northeast winds to Ord/mdw between about 12z and 
14z. Low ceilings over central Wisconsin may also spread 
southward...aided by the lake influence...but confidence is 
low...so have added sct010 in Ord/mdw/gyy tafs from 13z to 15z. 


Wind direction forecast remains tricky through the day today...but 
current thinking is that winds will back to west-northwest 
everywhere except gyy...which will hold onto northerly winds given 
proximity to the lake. Pressure gradient will diminish later in 
the afternoon...with lake breeze expected to make some headway 
inland...though it is uncertain how far. Have indicated a wind 
shift in the mdw taf during the late afternoon but not brought the 
shift to Ord. Light northeast winds could then redevelop late 
tonight into early Wednesday. 


Rc 


//Ord and mdw confidence...updated 09z... 


* high in wind forecast through about 9z-10z today...low 
thereafter. 


* Medium in low ceiling potential this morning...low in duration. 


Rc 


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


Wednesday...VFR. 


Thursday...shra/some thunderstorms and rain likely. Periodic IFR possible. 


Friday...chance of MVFR ceilings. NE winds 10kt or greater possible. 


Saturday and Sunday...primarily VFR. 


Izzi 


&& 


Marine... 
403 am CDT 


A fast moving clipper system will quickly move east of the 
southern tip of the lake this morning. Given strong southwest 
winds that occurred ahead of the low overnight...a brief burst of 
15 to 25 knots north winds appears likely on the southern tip of the 
early this morning. Have not issued a Small Craft Advisory but 
will monitor trends and issue a short duration advisory if 
necessary. Lighter winds tonight into Wednesday morning will 
shift south and increase during the day Wednesday and especially 
Wednesday night as a frontal trough approaches the lake. Warm air 
mass ahead of the trough will limit mixing over the Cold 
Lake...but expecting speeds to 30 knots given high sustained winds. 
Will likely need a Small Craft Advisory for the nearshore during 
this time. A period of stronger north winds is possible on Friday 
as low pressure moves up the Ohio Valley. Speeds will depend on 
the track and strength of the low pressure area.
