NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
459 am CDT Tue Oct 21 2014 


Short term: (through thursday) 
issued at 322 am CDT Tue Oct 21 2014 


Dry weather and seasonable temperatures will continue through 
tomorrow and into tomorrow night. 


A vort Max was located over northern Nevada early this morning. This 
system is forecast to lift northeastwards today, then move through 
the northern plains and into southern Canada tonight and 
tomorrow. Even though the vort Max itself will be located well 
north of MO/IL, it will still drag a weak cold front into the 
region tomorrow night and Thursday, bringing a chance of rain 
showers to parts of the area. Some models do show a few hundred 
j/kg of cape farther west across western MO, but instability looks 
much more limited over central and northeastern MO. 


Kanofsky 


Long term: (tonight through monday) 
issued at 322 am CDT Tue Oct 21 2014 


Model solutions depict a large ridge of high pressure building 
across the middle of the country from Friday through Sunday. High 
temperatures could warm to as much as 5-15 degrees above average 
during this time if 850 mb temperatures of 10-16 deg c are realized. 
Another low pressure system could bring a chance of rain to the 
area on Monday or early next week.
