NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
405 am CDT Mon Apr 27 2015 


Short term: (through late this afternoon) 
issued at 328 am CDT Mon Apr 27 2015 


Another quiet Spring day is expected today with highs in the 60s 
and occasional mid/high clouds across the area. 


Kanofsky 


Long term: (tonight through sunday) 
issued at 328 am CDT Mon Apr 27 2015 


There have been few substantial changes in the model guidance and 
therefore little change in thinking since the previous forecast. 
A slow-moving cutoff low pressure system was located near the 
Texas/nm border at 08z, and this system will slowly move eastward 
over the next few days. Precipitation with this system is expected 
to remain south of the cwa, although there is an outside chance 
that the extreme southern part of the County Warning Area could see a few rain 
showers on Tue. 


The latest European model (ecmwf) and Gem runs no longer depict a closed 500 mb low 
dropping southeast out of Canada and retrograding during the 
middle of the week, instead showing more of a shear axis passing 
over the region during that time. The latest GFS run does show a 
deep closed low developing over the Great Lakes and dropping 
southward, but its position with this feature is much farther east 
than what the European model (ecmwf)/Gem were showing 24hrs ago. Despite this 
variability, the overall trend in the models remains the same: the 
slow-moving cutoff low eventually interacts with another vort Max 
to form a deep trough over the eastern one-third of the Continental U.S. 
Towards the middle and end of the week. Expect some increased 
cloudiness with the passing shear axis, but there are no strong 
signals for widespread rain during the week. 


In the absence of large scale air mass exchanges, temperatures 
should be governed by diurnal heating, the effects of cloud cover, 
and a consistent northerly component to the low-level flow which 
is forecast to remain in place through the end of the work week. 
Expect gradually warming temperatures through the week with highs 
reaching the 70s by Fri. 


Kanofsky

Aviation: (for the 06z tafs through 06z Monday night) 
issued at 1138 PM CDT sun Apr 26 2015 


A large area of high pressure extending out of sthrn Canada will 
dominate thru the prd producing VFR conditions and a persistent 
north/NE flow. There will be overnight cirrus originating from 
convection across the sthrn plains and some diurnal cu tomorrow. 


Specifics for kstl: 


VFR conditions thru the prd with north/NE winds aob 12kts with diurnal cu.
