Severe Weather Alert Descriptions

 Lakeshore Flood Advisory, Beach Hazard Statement  Statement as of 3:30 PM CDT on May 30, 2015


... Lakeshore Flood Advisory remains in effect until 4 am CDT
Sunday...
... Beach hazards statement remains in effect through Sunday
evening...

* Lake Shore flooding... waves will build to 8 to 11 ft today
resulting in minor flooding in the typically flood prone
locations.

* Timing... into tonight.

* Impacts... portions of the Chicago Lake front bike path will
likely become inundated by large battering waves and
impassable... as well as other high wave prone locations.

* High wave action and dangerous swimming conditions expected
through Sunday evening.

Precautionary/preparedness actions...

A Lakeshore Flood Advisory indicates that onshore winds will
generate flooding of low areas along the Lakeshore.

Life threatening waves and currents are expected at the beaches.
People visiting the beaches should stay out of the water.

Rip currents are powerful channels of water flowing quickly away
from shore... which occur most often at low spots or breaks in
sandbars. Structural currents form along piers where longshore
currents and wave action flow into the structure. Rip currents
and structural currents can sweep you into deeper water.

Exposed beaches are more likely to experience the most
significant wave and current impacts.

Impacts at beaches with protective breakwalls or jetties will be
subject to orientation of structures as well as wind and wave
direction.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
507 PM CDT Sat may 30 2015 


Short term... 
239 PM CDT 


Through tonight... 


Strong cold front continues to make steady progress south across 
the County Warning Area with the lake adding its two cents in the form of locally 
stronger winds along the shore and temperatures several degrees colder 
(falling into 40s). Front will continue to work slowly southward 
though its progress should slow over our southeast County Warning Area as surface 
low over southwest Illinois ripples northeastward and temporarily 
slows its progress tonight. North of the front...unseasonably 
chilly temperatures and strong winds will be the rule tonight...both 
particularly the case along near the lake. 


Bigger concern tonight is with heavy rainfall potential from east 
central Illinois into Northwest Indiana. Water vapor imagery early 
this afternoon shows a well defined vorticity/nearly closed circulation 
evident lifting northeast into southeastern Missouri. This 
shortwave is forecast to continue NE tonight into Indiana with 
guidance in good agreement in developing rather strong middle-level 
f-general zone and associated deformation band on the northwestern 
flank of this system. Strongly suspect (and hope) the 12z NAM quantitative precipitation forecast 
is grossly overdone over Northwest Indiana...however am concerned 
about the potential for a low topped/shars (subtle heavy rainfall 
event) in the defo band as precipitable waters  are prognosticated to be in the upper 
echelons of what is possible this time of year over 1.75 inches. 
In addition...very high freezing levels (nearing 12kft agl) will 
favor warm rain processes and high precipitation efficiency. 
Considered a Flash Flood Watch for tonight for my southeast County Warning Area...but 
given uncertainties opted to hold off and just hit the heavy 
rainfall threat in hwo/grids. Assuming deformation band develops 
as advertised could easily see localized rainfall totals this 
evening in excess of 2 inches. Evening shift will need to closely 
monitor the evolution of anticipate defo band this evening and may 
need to consider a short fused Flood Watch and/or flood 
advisories.

Long term... 
305 PM CDT 


Sunday through Saturday... 


Lingering rain is expected across Northwest Indiana and possibly 
parts of eastern Illinois after daybreak Sunday. This should end 
by middle to late morning as the low moves northeast from central 
Indiana. By Sunday afternoon...the upper trough will be positively 
tilted enough that basically the southern stream part of it will 
detach and drift into the lower Ohio Valley. This will slow middle- 
level flow from turning northwest and likely slow clearing from 
northwest to southeast across the area on Sunday...with the 
Rockford/Dixon areas expected to become sunny by late morning 
while Pontiac to Northwest Indiana remaining cloudy through the 
entire day...with Chicago likely to scatter sometime in the 
afternoon. 


Anomalously strong and cool north-northeast winds for the final day 
of meteorological Spring will continue on Sunday with gusts of 25 
miles per hour expected with 30 to 35 miles per hour near the Lake Shore. Waves are 
forecast to peak from middle-evening into overnight with a gradual 
subsiding on Sunday. So the lake flooding threat is expected to have 
diminished by Sunday morning. The bigger story with the winds will 
be the continued cool temperatures. The 925mb temperatures on a 
consensus of model guidance are expected to be 4-5c which certainly 
look plausible given upstream upper air observations this 
morning. There have only been 10 days in late may with both that 
cold of temperature analyzed and northeast winds. The average high 
at ohare was 53 degrees on those days and have gone with that for 
the high forecast...which is a little over 20 degrees below 
normal. Meanwhile downtown immediately near the lake front will 
likely remain in the 47-50 degree range...especially with any 
upwelling to cool the nearshore waters minimizing any 
modification. 


The pressure pattern looks to keep enough of a gradient that despite 
850-925mb temperature that could support isolated middle 30s and a 
possible frost threat...the wind speeds look to be enough to keep 
lows more so in the lower to middle 40s with isolated upper 30s 
north. Quite the brisk start to kick off meteorological Summer. 


Beyond the weather pattern is quiet through midweek. Upper and middle- 
level heights look to likely build Wednesday into Thursday. With 
that have gone slower than a smart model blend for low chances of 
showers and storms late in the work week. If this trend 
continues...those mentionable probability of precipitation could probably be 
removed...but too far out at this point to show much improvement 
over that blend in the presently forecast pattern.

Aviation... 


//Ord and mdw concerns...updated 22z... 


* strong northeast winds this evening through much of Sunday 
* IFR to occasional LIFR this evening. 
* Moderate rain gradually tapering this evening. 
* Low level wind shear this evening. 


Mm/bmd 


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


Cold front working its way across northern Illinois has already 
dropped the Chicago area to 500 foot ceilings with north-northeast winds. As 
cold and dense air works its way down the lake to reinforce the 
cold front...wind speeds and gusts will considerably increase 
generally from 22z Onward. These gusts will remain in place 
through tonight as an already tight pressure gradient is aided by 
flow off of Lake Michigan. This combination will keep gusts in the 
25 to 30kt range through tonight. Just off the deck...winds will 
be even greater so did mention low level wind shear in the taf for 50kt of flow 
from the northeast through early evening. 


Into tonight...winds become more uniform and only slightly 
slacken. Continued flow off the lake will keep the NE winds in 
place...but the low levels will start to dry out midday Sunday. 
There may be some MVFR ceilings lingering daytime Sunday and the 
chance for precipitation is too low to mention in tafs at this 
time. Isolated showers are not out of the question Sunday.

//Ord and mdw confidence...updated 22z...

Marine... 
228 PM CDT 


North-northeast winds will continue to reinforce abnormally cool air 
across Lake Michigan through the remainder of the weekend. Gale 
force gusts have been observed at Waukegan Harbor early this 
afternoon and expect to see an increase in frequency. Gale force 
gusts are likely through the evening and even into at least early 
overnight across the southern part of the lake including the 
Illinois and Indiana nearshore areas. Waves will build rapidly into 
this evening across the central and southern part of the lake 
including the Illinois and Indiana nearshores...which should realize 
some of the highest waves of 8 to 12 feet...peaking from middle-evening 
through overnight. A very slow subsiding is expected on Sunday with 
continued but gradually diminishing northeast winds. 


Beyond the weekend action...conditions look relatively quiet on the 
lake this upcoming work week. After a ridge axis passes on 
Tuesday...winds will turn southerly for the latter half of the week 
prior to a cold front passage sometime late in the week into early 
next weekend.
