Area forecast discussion...updated 
National Weather Service St Louis MO 
928 PM CDT Sat Mar 28 2015 


Update: 
issued at 925 PM CDT Sat Mar 28 2015 


This evening's water vapor imagery indicates potent shortwave over 
eastern Montana and Wyoming zipping ESE, with latest nwp runs indicating the 
dynamics with this system reaching the mid-Missouri Valley by 
12z. 00z 850mb data shows strong warm air advection already occurring over the 
northern plains in advance of this feature, and this should 
increase even further overnight with the approach of the 
shortwave. However, air mass over the plains is extremely dry, and 
there is no obvious source of significant moisture for the 
increasing southerly flow to tap over the next 6-9 hours. While 
the power of warm advection should never be underestimated, 
believe the limited moisture is going to cause any measurable 
precip to struggle to reach our forecast area overnight. Going pop trend, 
which limits mention of precip to our extreme northwest counties 
in the 10-12z time frame, still looks reasonable. 


Still expect a bit of an increase in clouds overnight, either from 
some of the low level moisture trapped over the Ozarks sloshing 
back to the east, or from high clouds in advance of the shortwave 
pushing southeast during the predawn hours. Going temp trends 
still look good.

Short term: (through late tonight) 
issued at 345 PM CDT Sat Mar 28 2015 


Quiet weather tonight under shortwave ridging ahead of the next 
shortwave trof. Should see temperatures fall off fairly quickly 
this evening under a clear/mostly clear sky and light wind. 
However, think the temperature drop will be arrested overnight by 
increasing mid and high clouds ahead of the shortwave and also 
increasing southerly wind as the surface pressure gradient tightens 
ahead of the surface wave. Stuck pretty close to blended guidance 
for lows tonight, but those lows may occur a few hours before 
sunrise, with perhaps nearly steady or slowly rising temperatures 
through 12z.

Long term: (sunday through next saturday) 
issued at 345 PM CDT Sat Mar 28 2015 


Northwest upper level flow will prevail thru Tuesday across our 
region, with mostly quiet wx and a pair of weak cold fronts dropping 
thru. 


The only sensible wx forecast for this stretch is for Sunday, as an 
upper level disturbance edges our area to the north and west with 
strong warm air advection on the front-end. A band or two of showers is expected 
to form from this as a result, with the highest probs to the north 
and east of stl where likelys pops were retained, but more scattered 
coverage heading into central MO and the Ozarks. 


Otherwise, temps should warm up pretty well Sunday despite clouds 
and rain, with at or above MOS for most sites forecasted, which 
would result in 50s most areas with low 60s in central MO. 


Despite a cold front moving thru late Sunday, temps on Monday are 
expected to be warmer with flow already backed from the SW again. 
The higher MOS values for Max temps favored with decent sunshine 
anticipated. 


This warming trend should continue into Tuesday with another front 
coming down, but not until afternoon. Did not go as high as the mex 
MOS values, which would have had more confidence in them with a 
slightly later fropa, but nevertheless, went with Max temps in the 
low 70s for most areas. There is the potential for a low confidence 
shower event late Monday night into Tuesday associated with warm air advection, but 
this is not nearly as strong as the Sunday event. For now 
maintained the dry forecast. 


The Tuesday front will then linger thru much of the second half of 
the work week as upper flow shifts to more from the W-SW. 
Persistent shower and thunderstorm chances will reflect this period 
with mild temps. Some room to go even higher on temps south of the 
front Wednesday and Thursday if confidence can be increased in rain 
holding off, but very little skill in those specifics this far out. 


Temps expected to return to below normal following this wet period 
on Saturday with another cold front moving thru and a bit better 
cool airmass moving in.

Aviation: (for the 00z tafs through 00z Sunday evening) 
issued at 633 PM CDT Sat Mar 28 2015 


Surface ridge to continue sliding to the southeast away from 
forecast area ahead of next weather system. Southeast winds to 
veer to the south by daybreak and pickup with gusts to near 25kts 
at times. Will see some light rain possible mainly along and east 
of Mississippi River. Coverage will be scattered so for now just 
have vcnty shower mention at KUIN and Metro area tafs with low end 
VFR cigs. Then front to move through during the afternoon hours 
with winds veering to the west behind the front and gradually 
diminishing. 


Specifics for kstl:
