NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
352 PM CDT sun Jul 5 2015 


Short term: (tonight through monday) 
issued at 331 PM CDT sun Jul 5 2015 


The evening looks rather tranquil across the region with 
dissipating diurnal cumulus and a few high clouds filtering across the 
area. The return of southerly low level flow has lead to warmer 
temperatures today and greater moisture. Overnight there are 
indications by the NAM and especially the rap that we may see some 
spotty elevated showers and thunderstorms from south central MO 
into east central and southeast MO in the near dawn hours, then 
shifting east on Monday morning. A very weak peturbation in the 
northwest flow aloft, and more importantly veering and strengthening 
low-level flow in the 3000-7000 feet layer and attendant thermal and 
moisture advection could generate some activity in the 07-15z time 
frame. I have added some slight chance probability of precipitation to the forecast with 
this in mind. Otherwise milder temperatures on tap tonight and a 
rather warm day is on schedule for Monday. The models now all have 
a bit slower progress with the cold front, not entering far 
northwest MO until the 21-00z time frame. Given this slower speed 
and lesser clouds expected with the forecast warm air advection regime, I expect 
temperatures well into the 80s with a few spots around 90. We 
could also see some spotty diurnally driven pulse storms in the 
afternoon in the broad warm moist and unstable warm sector.

Long term: (monday night through next sunday) 
issued at 331 PM CDT sun Jul 5 2015 


Monday night into Wednesday still looks like a wet and stormy 
pattern with widespread multi-day average rainfall totals of 2-4 
inches. The biggest issue is just where the heaviest rainfall may 
focus with the models having some growing differences with time 
from Tuesday and beyond where the front may lie. The European model (ecmwf) has the 
most agressive southward push early on then wavers the front 
through the area late this week. Alternatively the GFS and NAM 
both don't move the front as far south and then waver it Tuesday 
night into Wednesday as surface waves move along it, finally 
pushing north of the County Warning Area by Thursday evening. The region spanning 
the frontal zone will be very moist and a broad region of deep low 
level convergence will focus widespread showers and thunderstorms 
with potential for heavy rain. We may ultimately need a Flash 
Flood Watch once we can pin down the region a bit better. 


Looks like precipitation chances will decrease into next weekend 
with a return of Summer heat.

Aviation: (for the 18z tafs through 18z Monday afternoon) 
issued at 1035 am CDT sun Jul 5 2015 


Area of low pressure will continue to move east through the 
Tennessee Valley with high pressure stretching form the Great 
Lakes to the Red River valley. As everything continues to move 
east a southerly wind will gradually increase into Monday. 
IFR/MVFR stratus moved into south central MO overnight with the 
weak south wind. This will have to be watched as it may make it 
into cou. Otherwise mostly VFR forecast with some morining fog and 
haze. 


Specifics for kstl: continued mostly VFR with some morning fog and 
haze once again as the light southerly wind will likely not be 
strong enought to stop in. NAM and GFS develop scattered showers 
and storms Monday afternoon, but given this is the last 6 hours 
of the period, and a vicinity would be all this is needed, will 
leave dry.
