NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Des Moines Iowa 
635 PM CDT Thursday Jul 24 2014 


Synopsis... 
issued at 316 PM CDT Thursday Jul 24 2014 


Low pressure over western South Dakota will move east and be over southern WI by 
Saturday evening. Cold front will trail the low and move through 
Iowa Saturday night. Low pressure will move northeast along the 
front Saturday night. Cool high pressure will build into the 
region Sunday through the middle of next week. 


&& 


Short term /tonight/... 
issued at 316 PM CDT Thursday Jul 24 2014 


Large area of Theta-E advection ahead of approaching low pressure 
system has allowed for area of thunderstorms across northern Iowa 
and western portions of the County Warning Area. Models have a poor handling on the 
current situation...indicating that precipitation will decrease. 
While Storm Prediction Center analysis shows a relatively unfavorable environment for 
storms...given ongoing precipitation and strength of Theta-E 
advection...anticipate this to continue through the late afternoon 
and evening hours. Precipitation appears to be elevated...and will 
continue to be with very limited surface based cape. Therefore any 
threats for severe weather will primarily be large hail. 


As low pressure system approaches...precipitation with shift to the 
north/northeast. In addition...low level jet is expected to 
increase...impinging on north and northeastern portions of County Warning Area 
beginning near 06z. Have therefore increased probability of precipitation beyond 06z. Low level jet is 
expected to push south somewhat near 12z...and have brought higher 
probability of precipitation further south. Models are a bit slower...and have hung on to 
precipitation through 12z. Precipitable water values overnight remain high...over 1 
inch...and locally heavy rainfall will be possible with 
storms...however dynamics decrease overnight...and anticipate severe 
threat will also diminish. 


Long term /Friday through Thursday/... 
issued at 316 PM CDT Thursday Jul 24 2014 


Warm front will lift across the County Warning Area with strong capping moving in 
rapidly during the day. 700 mb temperatures will warm to +16 with cin 
remaining greater than -50 even during maximum heading. Do not look 
for any precipitation in the County Warning Area after early Friday morning through 
Friday night..and only low probability of precipitation across the south with the wave 
passage Saturday and Saturday night. 


A strong push of warm air aloft and quick return to dew points in 
the 70s again for Friday. Much of the County Warning Area will not have a chance 
to recover enough to reach heat advisory criteria...but the 
southwest is likely to reach 105 or better for a couple hours 
Friday afternoon. Will hoist a heat advisory for those areas from 
17z-00z. Clouds and cooling will keep heat indices below criteria 
fro Saturday. 


Much of the rest of the forecast period will be dominated by cool 
Canadian high pressure. Temperatures will be below normal through the 
week. A dry weak is on tap until at least Thursday. Once the high 
pressure retreats to the east...return flow will bring a chance 
for thunderstorms Wednesday night into Thursday. 


&& 


Aviation...25/00z 
issued at 635 PM CDT Thursday Jul 24 2014 


Patch of rain showers currently affecting area may produce a brief local 
MVFR ceiling/visibility in the next couple of hours before dissipating...but 
probability at a given terminal is low. Thereafter expect a break 
in precipitation of several hours with a return to south-southeast winds and high 
ceilings...but overnight after 06z anticipate more thunderstorms and rain development 
though coverage is questionable so have handled with just thunderstorms in the vicinity for 
now. By 06z issuance convective trends may be revealing themselves 
allowing for more detail in the tafs. By midday Friday expect 
storms will have ended with VFR conditions prevailing during the 
afternoon. 


&& 


Dmx watches/warnings/advisories... 
heat advisory from noon to 7 PM CDT Friday for Adams-Cass- 
Ringgold-Taylor-Union.
