NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
639 PM CDT Thu Jul 24 2014 


Short term: (through late tonight) 
issued at 342 PM CDT Thu Jul 24 2014 


A gorgeous late July day is ongoing across the forecast area, with 
temps in the upper 70s and low 80s, dewpoints in the low 50s, and 
plenty of sunshine. 


Northwest upper level flow prevailed this afternoon with a few upper level 
disturbances keying off complexes of thunderstorms and rain over the mid-MO River 
Valley. These complexes are trying to push southeast into our 
region, but we are much too dry and stable for this rain to have 
much Success. Instead we are just seeing the convective blowoff 
slide into our area. 


It appears the convection will continue to weaken and dissipate as 
it pushes southeast late this afternoon and evening from Iowa with 
continued thin high cirrus clouds moving thru as the diurnal cumulus 
dissipates with the setting sun. A new round of thunderstorms and rain is expected to 
form around midnight in central Iowa and this is anticipated to have 
more Success in propagating southeast with our region not as dry and 
stable as before but should still be slow in moving towards US and 
probably in a weakening phase as it does so. Have not changed the 
pops for the northern County Warning Area as a result, with low mentionable values 
in place for late...after 09z. 


Clear skies for most areas and light winds from a slowly departing 
surface ridge will promote good cooling, however, with temps 
expected to drop into the upper 50s and low 60s outside of urban 
heat islands. Clouds are not expected to have much influence until 
thicker clouds arrive after midnight. 


Tes 


Long term: (friday through next thursday) 
issued at 342 PM CDT Thu Jul 24 2014 


Shortwave rounding the top of the ridge over the Dakotas should be 
near the Missouri/Iowa/Illinois border by 12z Friday. Models are 
forecasting a modest amount of elevated cape between 500-1000 j/kg 
ahead of the shortwave as it passes southeast across our central 
Illinois counties. Expect there to be some convection stretching 
into our County warning forecast area due to these factors and a 30-40kt low level jet nosing into 
southeast Iowa, however am not very confident on areal 
coverage/timing of precip. Am therefore keeping only chance 
pops...especially since surface based convection looks unlikely due 
to 200+ j/kg cinh. Looks like there will be another round of 
nighttime convection on Friday night as the upper level ridge 
flattens and the low level jet pushes into Illinois. Looks like the 
majority of the forcing will be east of the area in central/south 
central Illinois, however can't rule out far eastern sections of the 
County warning forecast area could see some isolated/widely scattered showers and storms 
overnight. Temperatures will be warming through Friday with highs 
reaching up to near seasonal normals as the cool surface high moves 
east and away from the region. 


Saturday still looks like the hottest day of the next 7 days. 850mb 
thermal ridge builds directly across the I-70 corridor with 
temperatures ranging from 24-26c. This would mix dry adiabatically 
down to around 100 f. Don't quite have the guts to go that warm 
just yet, especially with the possibility of some afternoon 
thunderstorms. That being said, guidance does look a little cool 
along and south of the I-70 corridor, so I did bump it up a bit. 
Soundings look pretty capped, but with falling heights aloft and 
with the potential for a front in the area I can't rule out the 
aforementioned afternoon thunderstorms. 


Saturday night looks like the best chance for precip as the next 
strong shortwave dips down across the upper Midwest and finally 
pushes a strong cold front into our area. Have mid-high chance pops 
for this period. Can't quite talk myself into likely yet due to the 
climatologically unfavorable time of day and relatively warm 
temperatures aloft. 


Medium range models continue to show the shortwave phasing up with 
the longwave pattern over eastern North America. The highly 
amplified trof allows a cool dry Canadian airmass to move south into 
the Continental U.S.. temperatures below normal temperatures in the upper 70s 
and low 80s will prevail through the first 1/2 of the week with lows 
in the low 60s. Temperatures will slowly moderate Wednesday into 
Thursday but still look below normal.

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 556 PM CDT Thu Jul 24 2014 


VFR fcst with sfc high sliding thru the Ohio Vly and near the East 
Coast by the end of the prd. Main fcst concern will be precip 
potential assoc with a couple upper lvl disturbances embedded in 
the northwest flow. The first of the two is currently dropping southeast out of 
Iowa. It is weakening and expect that trend to continue thru the 
evng as the precip moves into a drier more stable airmass. It is 
possible for the KUIN terminal to see a few sprinkles this evng 
though. The next disturbance should ignite another round of 
convection across eastern South Dakota...SW Minnesota and northwest Iowa overnight. This 
activity is also expected to drop southeast and may affect the KUIN 
terminal Friday morning. By then...a substantial increase in 
moisture is expected allowing the precip to hold together farther 
to the east. Still not confident that it will impact the terminal 
or slide just to the east...so left the vcsh group alone. It is 
not out of the question to have precip in or near the stl Metro 
area on Friday...but not confident enough in this scenario to 
include mention attm. Regardless whether it rains at any of the 
terminals or not tomorrow...there will be an abundance of mid/high 
lvl convective debris clouds. Winds should become srly by tomorrow 
allowing for return flow and aiding in the increase in moisture. 


Specifics for kstl: 


VFR fcst thru the prd. Two upper lvl disturbances will impact the 
region over the next 24-30 hrs. A batch of precip assoc with the 
first disturbance is dropping southeast out of Iowa this evng. It is 
weakening and is expected to continue to do so as it moves away 
from the better moisture and instability. The next disturbance 
should spark another round of tstms to across the mid-MO Vly 
overnight. This activity may graze the terminal from late mrng 
thru early aftn on Friday...but not confident enough in this 
scenario to include mention attm.
