NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
650 am CDT Thursday Oct 23 2014 


Discussion... 
303 am CDT 


A ridge of high pressure stretches from central Quebec southwest 
through lower Michigan into the Ohio Valley. Early this morning this 
ridge has been able to keep cloud cover displaced west of the 
region. Based on latest surface observation the pressure falls are not very 
large...which could be an indicator that later today the ability for 
the atmosphere to produce abundant moisture/precipitation may be 
diminished. Infrared imagery early this morning shows a moist channel that 
extends from the Canadian border of the upper Midwest...south to 
the Mexico border/western Gulf. The progression to the east has been 
very slow...and latest hi-res guidance indicates that as this 
feature pushes east it will encounter much drier air and diminish 
the coverage and intensity of precipitation. 


With the light winds and minimal cloud cover early this morning...some 
locations are beginning to see patchy fog develop...mainly across 
Northwest Indiana. Temperatures have been able to radiate into the middle 
30s...with the exception of the far western County warning forecast area where a thin 
cirrus deck has arrived and held temperatures in the upper 30s/near 40. 


As the moist channel slowly slides east today...expect a steady 
thickening to the cloud cover. Winds will turn southerly with some 
better mixing developing and perhaps bringing winds up to 10-20mph 
by late afternoon. Guidance has become more pessimistic with precipitation 
coverage/intensity later today...and as a result have backed off on 
probability of precipitation along with quantity of precipitation. The near surface environment still 
looks to remain relatively dry...although some moistening will 
occur. Expect the best precipitation coverage to occur further 
north...however will continue the mention of light rain across entire 
forecast area late this afternoon/early evening. Trough axis will be sliding 
east across east-central wisc by 3z. Temperatures today will warm into the 
50s for much of the area...and south of I-80 a few 60s. 


For tonight on the back side of the trough...and departing 
precipitation/cloud cover...there is some concern that patchy fog will 
develop. Upstream this has already been noted...and expect this 
similar setup to occur over a portion of the County warning forecast area overnight tonight 
but will hinge upon how quickly clouds will depart. Lows will 
generally be in the middle/upper 40s. 


Friday through Sunday... 
a weak lobe of vorticity is prognosticated to slide east across the Central 
Plains...arriving over the forecast area Friday aftn/eve. Local arw8km 
guidance and NAM suggest some light precipitation may develop with this 
system...but not expecting much to the coverage at this time. Have 
opted to hold onto the dry forecast...but may need to adjust probability of precipitation 
slightly to reflect a few sprinkles/light rain showers. Then by early 
Sat morning anti-cyclonic flow builds into the region and dries the 
atmosphere out. Surface ridge will remain in place through sun...then the 
middle-level ridge overhead flattens and the flow becomes quasi-zonal for 
late in the weekend into early next week. 


Temperatures Friday-sun will be slowly moderating...with highs in the 60s to 
perhaps a few low 70s Fri/Sat. A weak frontal boundary will slide 
across the region sun and could bring temperatures back into the upper 
50s/low 60s. 


Monday-Wednesday... 
ensembles are showing the western Continental U.S. Trough pushing east by early 
next week...helping to setup the potential for periodic chances for 
showers and perhaps a few thunderstorms in the Monday/Tuesday timeframe. 
Temperatures Monday should rebound with a southwest flow and push into the upper 
60s/low 70s. Then increased cloud cover Tuesday/Wednesday will keep temperatures in 
the upper 50s to low 60s.

//Ord and mdw concerns...updated 12z... 


* southerly winds 10-12 kts...with a few higher gusts possible... 
middle morning through late afternoon. 
* Chance of rain showers late afternoon through middle evening. 
* MVFR ceilings tonight. 
* Fog possible Friday morning. Cms 


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


Light fog has formed across northeast Illinois and some of the terminals 
but this should be short lived this morning. Further east into 
Northwest Indiana...more widespread and dense fog has developed 
and this will take a few hours to dissipate later this morning. 


A weak trough moving across Minnesota and Iowa will reach the area later 
this afternoon and this evening as it dissipates. Light showers 
will be possible across northwest Illinois by early this afternoon and 
then across the rest of terminals mainly this evening. Still 
fairly low confidence regarding coverage and intensity so have 
kept vicinity mention. VFR ceilings are expected until this evening 
when precipitation saturates the low levels and MVFR ceilings are expected 
to develop. These ceilings should begin to clear across northwest Illinois 
overnight and possibly as far east as Ord/mdw by sunrise Friday 
morning. Where clouds do clear...expect fog to develop which may 
become dense. Included fog at rfd/dpa as confidence further east 
is too low at this time. 


South/southeast winds 4-8kts to start will increase to 10-12kts 
this morning and turn to the south/southwest. There will also 
likely be some gusts into the 15-17kt range but not sure how 
prevailing they will become. Thus left them out of this forecast 
and trends will need to be monitored. Winds turn light southwest 
this evening and then will become light and variable tonight. Cms 


//Ord and mdw confidence...updated 12z... 


* high for wind direction...medium for speeds and possible gusts. 
* Medium for rain showers late afternoon/early evening. 
* Medium for MVFR ceilings tonight. 
* Low for fog Friday morning. Cms 


//outlook for Ord/mdw for 00z Saturday-12z Thursday...updated 12z... 


* Friday night...dry. MVFR/fog possible. 
* Saturday...dry/VFR. Gusty west/northwest winds. 
* Sunday...dry/VFR. West winds becoming southeast. 
* Monday...dry/VFR. Gusty south winds. 
* Tuesday...chance of rain showers. Strong/gusty westerly winds. 
* Wednesday...chance of rain showers. West winds.

Marine... 


245 am...fairly active pattern is expected into early next week. 
High pressure extending from Quebec southwest through the Central 
Lakes region will split today...with the high weakening and moving 
south into the Ohio Valley tonight. Low pressure over Manitoba 
will move north today as a weak cold front approaches the western 
lakes. The gradient will tighten some today ahead of this front... 
but the front is expected to dissipate over the western lakes 
tonight. Thus winds may shift westerly for a time but will quickly 
go back southwest by Friday morning. 


The low lifting north over Manitoba will be absorbed by a stronger 
low moving across central Canada tonight and Friday. This low will 
then move across Ontario reaching James Bay Saturday afternoon as 
it deepens. Another cold front trailing this low will move across 
Lake Michigan late Friday night into Saturday morning. Ahead of 
this front...southerly winds will increase again. Behind the front 
winds will shift northwest 20-25kts and may approach 30 kts for a 
time Saturday afternoon into Saturday evening. 


A weak ridge will move from the plains Saturday to the western 
lakes Sunday...with winds quickly shifting from west Sunday 
morning to south/southeast Sunday evening. The gradient will then 
tighten with increasing southerly winds as a large area of low 
pressure develops over the plains Sunday into Monday. Cms
