NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Chicago/Romeoville Illinois 
403 am CDT Friday Jul 25 2014 


Discussion... 
324 am CDT 


Synopsis...a tricky unsettled forecast is expected today through 
Sunday. Then things quiet down for the beginning of the work week. 
Saturday will be the warmest day in the forecast with highs near 
90. Temperatures then fall to below normal Sunday and slowly begin to 
climb back to near 80 by late next week. 


Today and tonight... 
an upper level high is over the southwest U.S. And Southern Plains 
while low pressure is over the Alberta/Saskatchewan border. The 
high will slowly retrograde through Monday afternoon to over the SW 
U.S. While the low passes over Lake Michigan Sunday evening. At the 
surface high pressure is over the Ohio River valley and it will move 
off the Atlantic coast tonight. There are two surface lows...one 
over the northern plains and the second Colorado-located with the upper 
level low over the Alberta/Saskatchewan border. 


Convection is ongoing over west central Minnesota and Iowa very 
early this morning. The storms will be moving into a more stable 
environment and the low level jet will also be weakening as it 
pushes east. There is high confidence that the storms over Iowa will 
weaken as they approach the County Warning Area...but expecting showers and a couple 
of storms to reach the I-39 corridor by middle morning. Some guidance 
members suggest showers and storms could linger into the middle 
afternoon hours but thinking they will dissipate by the early 
afternoon. 


High clouds will be overhead and may limit heating a bit...as such 
left high temperatures today in the upper 70s. 


Multiple rounds of storms are expected with the second round 
spreading south this evening. The low over the plains will weaken as 
it pushes east and form an open trough. The lows warm front will 
approach the region tonight and expecting storms ahead of it. The 
nose of the low level jet will also be over northwest Illinois this 
evening providing additional lift. Cape will be limited with 
model soundings showing shallow areas of cape at 1000 j/kg or less. 
Precipitable water values will be around 1.9 inches so torrential downpours are 
the most likely hazard. 


Saturday... 
the plains low/trough moves over the Midwest with Saturday 
having the best chance for severe weather especially south of I-88. 
Precipitable water values remain high around 1.8 inches in the morning and then 
increase to 2-2.3 inches south of I-80 Saturday afternoon. Cape 
values will be much more healthy in the 3000 j/kg range especially 
along and south of the I-80 corridor. Expecting storms to fire 
along the lows cold front Saturday afternoon and evening with the 
chances of showers and storms increasing as you head south. Some of 
these storms may be severe with torrential downpours. Hail and wind 
look to be the main severe threats. 


Saturday will feel unpleasant to many with highs in the upper 80s 
and high dewpoints. Maximum heat indices will be in the 90s...with middle 
to upper 90 heat indices expected south of I-80. 


Sunday... 
the low over Canada drifts southeast moving over Wisconsin Sunday. 
Additional thunderstorms are possible north of the I-80 
corridor...with the best chances along the Illinois/WI state line. The 
storms push east of the County Warning Area in the evening. Cooler air associated 
with the low also spread south with highs on Sunday only expected to 
get into the low to middle 80s. Overnight lows will be around 
60...except for downtown which will be in the low 60s. 


Monday through Thursday... 
we remain under the upper level trough through next week with a 
surface high moving over the region by middle week. There are 
occasional chances of showers and storms but none of those chances 
look all that impressive at this point. The bigger story will be 
another extended period of below normal temperatures...although 
temperatures will be slowly rising through the end of the forecast 
period.

Aviation... 


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


* chances for mainly light rain showers today. 


* Chances for thunderstorms and rain after 00z. 


//Discussion...updated 06z... 


High pressure across the Ohio River valley will continue to depart 
to the east while a trough of low pressure inches eastward from 
the Dakotas today. Southerly flow will increase today and with 
that will come more moisture. Remnant showers and possibly a few 
storms are likely to make it into northwest Illinois late this morning 
into early afternoon. The focus for these should wane into the 
afternoon...however overall instability aloft will be on the 
increase...so it is difficult to say how showers will behave 
further eastward toward Chicago. Thunder potential looks to be 
greater during the evening into early overnight as another upper 
disturbance moves over the area. However...with the atmosphere 
being moist and unstable cannot rule out a thunderstorms and rain at anytime 
tonight. 


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


* low in precipitation coverage and timing this afternoon and 
tonight. Although high that any precipitation prior to 00z would be 
mainly light and VFR. 


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


Saturday-Sunday...chance of thunderstorms and rain. 
Monday-Tuesday...VFR. 
Wednesday...slight chance of thunderstorms and rain.

Marine... 
228 am CDT 


Southerly flow will increase over the lake today as high pressure 
scoots eastward from the Ohio River valley. The surface trough 
leading to the increase in winds will arrive early 
Saturday...however weaken to the point where it will not shift the 
winds much if any from the south-southwest. The low pressure 
driving this trough will evolve over the lake on Sunday turning 
winds northerly and driving a sharp increase in speeds Sunday 
night and persisting into Monday. For July standards these wind 
speeds once again will be quite strong with even possibly some 
gale force northerly gusts late Sunday night into Monday morning. 
With once again a long fetch waves should reach heights of over 6 
feet over much of the lake with even possibly up to 10 feet again 
across the far south...primarily near the Indiana shore.
