NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
657 am CDT Sat Jul 4 2015 


Short term: (through sunday) 
issued at 231 am CDT Sat Jul 4 2015 


A dry Holiday weekend is anticipated as surface high pressure builds 
across Missouri and Illinois. Temperatures will gradually warm today 
and tomorrow as 500mb heights increase and winds become more 
southerly on Sunday as the ridge moves east of the area. 


Cvking 


Long term: (monday through friday) 
issued at 231 am CDT Sat Jul 4 2015 


Upper level trough traversing Canada and northern plains tomorrow 
and Monday will send a cold front into the lower Missouri and 
middle Mississippi River valley region Monday night and Tuesday. 
The front is expected to slow down considerably as it becomes 
quasi-stationary over the region by Tuesday evening with models 
hinting at a surface wave traversing the region Tuesday night and 
Wednesday. Increasing low level moisture and instability...coupled 
with precipitable water values in excess of 2 inches once again...will lead to 
another favorable setup for heavy rainfall Monday night through at 
least Wednesday. Have continued the trend of increasing probability of precipitation and 
will include the mention of heavy rainfall in the severe weather potential statement. The latest 
ecwmf paints a swath of 3 to 5 inches of rainfall along the I-44 
corridor in Missouri and I-70 corridor in Illinois next week which 
would only aggravate ongoing flooding. Temperatures will be near 
normal ahead of the front on Monday...with unseasonably cool 
conditions Tuesday and Wednesday thanks to cloud cover and 
precipitation. 


Model guidance gives some indication that the front will try to lift 
back north of the region on Thursday with temperatures moderating to 
normal values by the end of the week. Have my doubts that the front 
will make much progress north as upper level pattern remains active 
and zonal which is why chance probability of precipitation remain in the forecast through 
Friday.

Aviation: (for the 12z tafs through 12z Sunday morning) 
issued at 646 am CDT Sat Jul 4 2015 


Specifics for kcou, kuin: IFR to MVFR fog across the region should 
begin to mix out this morning. VFR conditions are expected for the 
rest of the day due to subsidence from a high pressure center 
moving across the region. Light winds will become easterly to 
southeasterly with time. 


Specifics for kstl, ksus, kcps: IFR to MVFR fog across the region 
should begin to mix out this morning. VFR conditions are expected 
for the rest of the day due to subsidence from a high pressure 
center moving across the region. Smoke from Independence day 
fireworks in the metropolitan area may be slow to mix out tonight and 
could contribute to haze at metropolitan area taf sites, especially after 
05/02z.
