NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
623 am CDT sun Aug 2 2015 


Short term: (through late this afternoon) 
issued at 455 am CDT sun Aug 2 2015 


Thunderstorms have developed early this morning over south central 
Iowa in an area of low level moisture convergence on the nose of a 
30kt low level jet. Rap shows that this low level convergence will 
move across the northern part of the County Warning Area this morning. Will keep 
isolated thunderstorms going over this area through at least the 
morning hours. 


Went with a blend of the MOS guidance for highs today which is 
supported by mixing down the 850mb temperatures. 


Britt 


Long term: (tonight through saturday) 
issued at 455 am CDT sun Aug 2 2015 


(tonight through tuesday) 


Cold front will move down into the area tonight ahead of a weak 
shortwave in northwesterly flow aloft. Still expect scattered 
thunderstorms to develop in the weak moisture convergence along 
the cold front in areas along and north of I-70. Isolated 
thunderstorms will continue into Monday over the southern half of 
the County Warning Area as the cold front shifts to the south. Chances for storms 
will increase Monday night into Tuesday night as the front stalls 
over the area as stronger shortwave trough moves across the area. 


(Wednesday through saturday) 


The chance of thunderstorms will continue over the area through 
Friday as the front will remained stalled Missouri and Illinois. 
Both the European model (ecmwf) and GFS are showing a series of shortwaves moving 
over the stalled front during this period. High pressure will 
finally move into the area by Saturday providing a dry day. Went 
with below temperatures because of expected clouds and rain chances.

Aviation: (for the 12z tafs through 12z Monday morning) 
issued at 616 am CDT sun Aug 2 2015 


Thunderstorms and rain over north central MO are expected to continue moving southeastward. These 
storms are not currently anticipated to impact uin...but can not 
be ruled out and will be in the region. Otherwise, thunderstorms and rain may also 
impact uin this evening as a cold front approaches the region. 
However...thunderstorms and rain should dissipate as they approach the uin region and 
will therefore keep out of taf at this time. Otherwise, winds will become 
southwesterly this morning and westerly as the fnt approaches. 


Latest model guidance suggests isod to scattered thunderstorms and rain will be possible 
this afternoon into early evening across portions of Eastern 
Ozarks...possibly as far north as the stl/sus/cps region. Chances of 
development and impacting these terminals is too low to mention in 
the taf at this time.
