NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
313 PM CDT Mon Apr 27 2015 


Short term: (through late tonight) 
issued at 256 PM CDT Mon Apr 27 2015 


Another night of tranquil and relatively cool weather is expected 
across the area. High pressure will remain in control in the low 
levels while the upper low moving eastward through the Southern 
Plains will spread high clouds into the area. The majority of the 
region should see lows in the 40s.

Long term: (tuesday through next monday) 
issued at 256 PM CDT Mon Apr 27 2015 


A tranquil and predominately dry weather pattern with temperatures 
at or below average will remain in place through the end of the 
week. High pressure will be maintained in the low levels with a 
northeast-north component in the flow. Two main upper systems 
will bring bouts of cloudiness. The first remains the upper low 
which will move east from the Southern Plains into the lower MS 
valley on Tuesday and then into the Tennessee Valley on Wednesday. 
Precipitation with this system is expected to remain to the south 
owing to the dry low level northeast flow. A short wave is also 
forecast to drop southward through the middle MS valley late 
Tuesday night into Wednesday. This system is weaker in the latest 
guidance. It still bears watching for potential for some "surprise" 
diurnally driven spot showers Wednesday...namely in eastern MO 
into Illinois. Another significantly stronger upper low will dig 
southward from the Great Lakes through the western Ohio Valley and 
into Tennessee Valley on Thursday which could produce a spot shower in 
far eastern parts of the County Warning Area in Illinois. Currently confidence and 
probability is too low to mention any precipitation chances in the 
forecast, but they bear watching. 


The upper air pattern across the Continental U.S. Will undergo deamplification 
and transition to a flatter more zonal regime Friday into the 
weekend. Associated with this will be height rises aloft as flat 
ridging builds east through the MS valley. In response the 
dominate surface high will finally retreat east on Friday bringing 
a return of southerly flow and attendant increase in low level 
moisture and warmer temperatures. The ensuing warm advection 
regime along with weak low amplitude disturbances in the westerly 
flow aloft will result in increasing chances of showers and 
thunderstorms Friday night into the weekend. The greatest 
probability will be across northern sections in response to an 
encroaching east-west front late Saturday into Monday.
