NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
651 am CDT Thu Jul 24 2014 


Short term: (through late this afternoon) 
issued at 333 am CDT Thu Jul 24 2014 


Surface ridge will remain overhead today with mostly sunny skies, 
lower dewpts and cooler temperatures. Highs will only be in the 
upper 70s to low 80s. 


Byrd 


Long term: (tonight through wednesday) 
issued at 333 am CDT Thu Jul 24 2014 


By tonight, surface ridge begins to move off to the east allowing 
southerly winds and low level moisture to return once again. Models 
continue to develop a complex over Iowa on nose of low level jet 
with southern edge just skimming far northern portions of forecast 
area after 06z Friday. Kept slight chance pops there for now. 
Otherwise, dry conditions to prevail with lows in the upper 50s to 
low 60s. 


On Friday, complex to slide southeast across Illinois with northeastern 
portions of forecast area on periphery of complex. Depending on 
coverage of activity and cloud cover associated with it, 
temperatures are hard to pin down. For now have highs ranging from 
the low 80s far east to the low 90s over central MO. 


By Friday night, main cold front to begin sliding southeast through 
forecast area. With increasing low level jet once again and 
increasing moisture, will see activity fire on nose of low level 
jet along and east of Mississippi River. Will also see milder overnight 
temperatures with lows only in the upper 60s to mid 70s. 


Despite 850 temps between 22 and 24c, high temperature forecast will 
be tricky on Saturday. With ongoing storms possible along frontal 
boundary that will be moving through, could see a wide range of high 
temperatures. For now kept forecast area rather warm with highs in 
the low to mid 90s, and with dewpts in the low 70s, heat indicies 
will approach 100 in many locations. Another issue will be the 
possibility of severe weather especially Saturday afternoon and 
Saturday night. High CAPES, plenty of low level moisture, and 
shortwave tracking along boundary, could see complex develop and 
slide east. Storm Prediction Center has put most of forecast area in a slight risk for 
day 3. 


Frontal boundary and storms to finally exit region by late Sunday 
with surface ridge building in for the first part of the work week. 
Highs Monday through Wednesday will be in the upper 70s to low 80s.
