NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
334 PM CDT Wed Jul 23 2014 


Short term: (through late tonight) 
issued at 333 PM CDT Wed Jul 23 2014 


Front has pushed into southeast MO and extreme southern Illinois this 
afternoon. Although a few storms have been able to form in the 
residual instability north of the front they too are sagging south, 
and should exit southern tip of Reynolds County no later than 22z. 


Weather trends for the forecast area heading into the overnight hours will be 
controlled by large high pressure ridge working its way south from 
the upper Mississippi Valley. Although dewpoints pooled north of the 
frontal boundary have kept humidity levels fairly high along and 
south of I-70 this afternoon, leading edge of much drier air is 
currently working into northern sections of the fa, and this drier 
airmass will overspread the entire County Warning Area throughout the night. 
This dry and cool airmass along with clear skies should yield min 
temps that are about 10 degrees below late July averages, with lows 
expected range from the mid 50s to low 60s.

Long term: (thursday through next wednesday) 
issued at 333 PM CDT Wed Jul 23 2014 


Surface ridge will build southeast from Wisconsin into the 
mid-Mississippi Valley on Thursday, and then continue east into the 
Ohio Valley Thursday night into Friday. Should see temperatures 
well below normal Thursday and Thursday night with low humidity. As 
the high moves into the mid-Atlantic region on Friday, we should see 
a return of more typical Summer heat and humidity, especially across 
central and northeast Missouri as southerly flow ramps up. Could 
see some warm advection showers/thunderstorms Friday, primarily 
across northern/northeastern portions of the County warning forecast area as the low level 
jet strengthens ahead of a weak shortwave rounding the upper level 
ridge. This should suppress temperatures somewhat on Friday 
afternoon. 


By Saturday the next strong ridge-running shortwave will be dipping 
southeast out of Canada into the northern plains and upper Midwest. 
Strong southerly flow will bring more heat and humidity into the 
region, and this will likely be the warmest day of the next 7 with 
highs in the middle...and perhaps upper 90s. The shortwave will 
phase with the long wave trof over eastern North America allowing 
another cool Canadian airmass to dip into the eastern Continental U.S.. medium 
range guidance is in decent agreement that the cold front ahead of 
this airmass will plow through the area on Sunday with another shot 
at precipitation. There are some discrepancies between the GFS and 
European model (ecmwf) as to the extent and perhaps the intensity of the 
precipitation, so will stick with mid-high chance pops at this time. 
After the front moves through and high pressure moves in, expect 
another round of spectacular late July weather with below normal 
temperatures and low humidity into the middle of next week.

Aviation: (for the 18z tafs through 18z Thursday afternoon) 
issued at 1245 PM CDT Wed Jul 23 2014 


Band of Post frontal St/SC that formed and/or advected into area 
from SW and central Illinois has given all taf sites but kcou a very 
definite autumn look throughout the morning. However, over the 
last 90 minutes or so visible satellite pics indicate that this cloud 
deck (which was roughly centered on a line from just W of KUIN to 
near kstl at 16z) is beginning to break up and ceilings are 
beginning to rise. So...believe MVFR cigs in the stl Metro should 
climb aoa 3kft over the next hour or so...with sct-bkn clouds 
3-5kft being the primary sky condition for most of the area during 
the afternoon. All of this cloudiness should dissipate heading 
into the evening hours with loss of heating and with much drier 
air advecting into the region, with clear skies and light 
northeast winds expected overnight. 


Specifics for kstl: bases of MVFR clouds over the area at midday 
should climb above 3 kft over the next hour or so...with 
additional thinning of the clouds producing sct-bkn deck 3-5kft 
throughout the afternoon. The clouds should totally dissipate by 
early this evening, leaving clear skies and light northeast winds 
for the overnight hours and into Thursday morning.
