NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
1110 am CDT sun Apr 19 2015 


Update... 
952 am CDT 


I made some updates to the forecast for today to raise 
temperatures and push off the timing of the rain chances. 


Water vapor imagery indicates our middle/upper level disturbance of 
interest for later today now lifting northward across western 
Kentucky. This feature is currently supporting an area of 
northward moving showers across southern portions of Illinois and 
Indiana. Therefore...this area of showers will gradually work 
northward across northeastern Illinois and northwestern Indiana 
during the afternoon. It appears the threat for thunderstorms will 
be very low with this activity...with trends suggesting no 
lightning strikes over the past few hours...so I have removed the 
mention of such this afternoon. In addition...with the slower 
onset of precipitation today...it appears temperatures will be able to 
warm to near 70 in most areas away from Lake Michigan...so I 
raised high temperatures today.

Short term... 
340 am CDT 


Through Monday... 


Upper air analysis early this morning depicts deep upper level low 
pressure now pushing into western Kansas. Multiple vorticity maxes are 
rotating around the low. The strongest of these exist in Texas and 
through the Central Plains...with some smaller scale waves extending 
into eastern MO/far western Illinois were some scattered thunderstorms 
were ongoing. A northern stream shortwave is entering the northern 
plains with some showers out ahead of it as well. At the 
surface...the cold front that passed through northeast Illinois and 
Northwest Indiana Saturday has pushed into central Illinois...but has 
likely completed its southward retreat and has washed out over the 
past few hours. Over the local area...much drier NE flow exists with 
dewpoints in the middle to upper 20s in the city to near 40 
south...though dewpoints are pooling along the front in the upper 
40s just south of the lot County Warning Area. The surface low that is expected to 
develop from the southern stream shortwave is also taking shape over 
the southern states with a warm frontal boundary extending from 
western Arkansas through the lower Tennessee Valley. An expansion of 
lower cloud tops on infrared imagery along and ahead of the warm front is 
occurring. 


Low level warm/moist advection will continue its slow progression 
northward under modest south/southeast flow. Deeper moisture/lift 
really hold off until the afternoon period across most of the area. 
A somewhat complicated evolution as a main surface low center is 
forecast to strengthen as it lifts north through Indiana today then 
further strengthen tonight into Monday while several additional 
surface lows develop and eventually merge with the main low center. 
The surface low will eventually become driven by a combination of 
the SW flow ahead of the southern stream upper low and the 
northern stream shortwave. 


Of note later today...expect coverage of showers to initially be 
slow given the drier air place...but increasing ascent aloft...low 
level south-southeast isentropic ascent ahead of the low and wrapping around the 
closed circulation extending through 850 and even 700 mb combined 
with modest lower level fgen should allow for a blossoming of 
showers across the area later this afternoon and evening. The 
highest precipitable water axis expands across Indiana today but should get 
wrapped into NE Illinois. Rap most unstable cape values relatively 
low but do expand from southeast to northwest this afternoon and this coupled with 
the punch from the dry slot of this system may enable a few T-storms 
as well...so some of the showers will have a modest kick to them in 
the moderate/heavy rainfall department. Expect that north central 
Illinois may be under a bit of squeeze play from these two 
systems...thus while showers are still expected...higher confidence 
exists in coverage farther east. 


This evening the first main shortwave will be passing NE while the 
main southern stream energy passes east through the Ohio 
Valley...and the northern stream shortwave lags behind back in 
MN/IA. There is also the loss of deeper moisture...therefore expect 
showers to taper/end/turn to drizzle possibly overnight for a time. 
Then Monday morning we get the coupled upper level forcing from the 
northern stream low and surface cold front which will likely bring 
another round of showers Monday morning. Showers will ease Monday 
afternoon. It will be quite breezy/windy behind the front on Monday 
in the cold advection regime.

Long term... 
340 am CDT 


Monday night through Saturday... 


The theme of the extended will be the unseasonably cool weather. A 
high amplitude pattern will be in place with strong upper level 
ridging extending well north into the Canadian rockies and similarly 
high amplitude ridging in the North Atlantic. That leaves our 
northern stream shortwave from Sunday/Monday with no where to go. 
This will keep much of the eastern half of the County...including 
our region...under cool northwest flow. This pattern also favored 
strongly sheared out and elongated vorticity maxes to pivot through 
bringing periods of showers. With precipitable water values quite low in this 
airmass...much of the period will be dry and even the showers should 
not be very strong. But more importantly...seasonal average 
highs/lows for late April are the lower 60s (mid 60s south) and 
lower 40s respectively...and much of this period will feature highs 
in the 50s and lows in the middle 30s...possibly cooler a night or two 
if winds are lighter. Temperature anomalies are not that extreme 
though...so record cold is not anticipated.

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


* east winds between 10-15kt into this evening. 


* West winds gusting to 20 knots tomorrow. 


* Rain overspreads taf sites later this afternoon through tonight. MVFR 
visibility under heavier showers. 


* Low end MVFR ceilings develop...possibly IFR conds develop by 3z 
through daybreak Monday. 


* A second round of rain arrives early Monday morning.

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


East winds continue to keep the low levels relatively dry and lack 
of low clouds...however moisture is creeping north across southern 
IL/in. Winds will occasionally gust to 20kt through midday...then 
expect with the abundance of moisture and rain the gusts may 
become less frequent with sustained winds increasing slightly to 
around 12-15kt. As a low pressure lifts northeast towards the region 
tonight...ceilings are expected to lower to MVFR and likely to IFR 
conds with bases around 800ft above ground level by 3z. A few guidance members 
suggest ceilings may dip further to around 400ft above ground level by 6z as a brief 
lull in the precipitation is poised to lift overhead. At this time will 
mention vcsh by 6z Monday...which may end up as drizzle or light rain. 
Ceilings will remain IFR through daybreak Monday...until a tight gradient 
returns and winds increase from the west/northwest. This should help 
to lift ceilings back to MVFR and eventually VFR conds by later Monday. 


Beachler 


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


* high confidence in rain timing...medium-high confidence in 
precipitation coverage this evening. Medium confidence in precipitation 
coverage tonight and Monday morning. 


* Medium confidence in wind speed and direction after 18z. 


* High confidence in ceilings becoming at least MVFR and possibly 
IFR...medium confidence in timing. 


Jee 


//outlook for Ord/mdw for 00z Tuesday-12z Sunday...updated 12z... 


Monday night...MVFR becoming VFR. 


Tuesday...slight chance PM rain showers...but mainly VFR. Gusty west winds. 


Wednesday...slight chance rain showers. Mainly VFR. West-northwest winds. 


Thursday...VFR. North-northeast winds. 


Friday...mainly VFR. Chance PM rain showers. 


Saturday...mainly VFR.

Marine... 
257 am CDT 


Low pressure over the Central Plains will slowly lift northeast 
towards the lower Great Lakes region tonight/early Monday. Guidance 
continues to indicate the gradient will tighten across the 
lake...however this appears to be more focused along the southern 
tip of the lake. With the continued easterly winds...it is 
possible marginal small craft conditions may develop for the 
Illinois shoreline later today into tonight. The low pressure will 
then approach the lake and briefly weaken the gradient early Monday. 
Then as the low lifts northeast later in the day Monday...it will 
deepen and merge with another low...which will create a tight 
gradient over the lake and increasing west/northwest Tuesday. After 
Tuesday the dominant wind direction will be northwest through middle- 
week...before relaxing to the west. This will allow higher waves 
to be focused in the southern half of Lake Michigan through middle- 
week.
