Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
509 am CST Fri Mar 6 2015 


Short term: (through late this afternoon) 
issued at 313 am CST Fri Mar 6 2015 


Some mid level cloudiness across the western half of Iowa ahead of a 
northwest flow shortwave and in a region of low-mid level warm air 
advection will move eastward through parts of northeast MO and west 
central Illinois this morning. Warmer temperatures can be expected this 
afternoon as the surface ridge extending from northeastern Arkansas 
northeast through southern Illinois moves southeastward and the surface 
wind becomes south-southwesterly across our forecast area. The 
models shift the zero degree c 850 mb isotherm eastward to the 
Mississippi River by 00z Saturday. Went closer to the warmer GFS 
MOS guidance for high temperatures today, particularly in areas 
without snow cover from central MO eastward through the St Louis 
Metro area. 


Gks 


Long term: (tonight through thursday) 
issued at 313 am CST Fri Mar 6 2015 


The trend to more typical early March temperatures should 
continue to be the primary forecast trend as we head into the 
weekend and early next week. As upper air flow regime over all but the 
extreme southern Continental U.S. Takes on a west-northwest look, the cold 
air that has been locked over the eastern half of the country for 
the past few weeks will begin retreating into southeast Canada and 
New England, allowing a more moderate air mass to spread from the 
plains to the mid- Mississippi Valley. Shortwaves embedded in the 
west- northwest flow will make several attempts to bring some 
cooler air our way, but with the pattern blocking any strong 
southward intrusion of cold air these cool Downs should be 
relatively minor. 


Believe that the warmup and strong sunshine that occurs today will 
be a "snow eater" in many parts of the cwa, so by Saturday any 
impacts of existing snow cover on temperatures will likely be 
fairly minimal and confined to our far southeast counties. With a 
westerly wind component advecting temperatures from the snow-free 
areas of western MO and lots of sunshine, forecast highs for 
Saturday will continue to lean towards the warm side of guidance. 
I've placed the warmest temps (55-60) along the thermal ridge 
progged along and just south of the i70 corridor in Missouri, with 
highs in the upper 40s and lower 50s elsewhere. 


A bit of cooler air oozing into the region on Sunday along with 
additional high cloudiness should keep highs near their average 
early March levels, with similar readings expected on Monday. 


(Tuesday-thursday) 


00z guidance continues to indicate a pronouced (and for most, a 
welcomed) warmup in the offing for the mid-Mississippi Valley 
heading into the middle of next week as heights build across the 
central U.S. Initial surge of warmth on Tuesday should push most 
areas west of the Mississippi to around the 60 degree mark, with 
highs in the 60s over most of the region by Wednesday and 
Thursday. 


Precipitation chances should remain quite low through the middle 
of next week. However, there appears to be some agreement in 
medium range solutions that remnants of southwest U.S. Upper level 
low will drift our way by the end of the period, and have added 
some low pops to southeast sections of the forecast area for Thursday and 
Thursday night.

Aviation: (for the 12z tafs through 12z Saturday morning) 
issued at 452 am CST Fri Mar 6 2015 


VFR conditions this forecast period with just some mid-high level 
clouds expected. The NAM MOS guidance appears overdone with its 
boundary layer moisture and low level clouds its forecasting for 
uin this evening. S-sely surface winds with strengthen and become 
swly late this morning and early this afternoon as surface ridge 
extending from northeastern Arkansas northeast through southern Illinois moves 
southeastward. Swly surface winds will continue tonight. 


Specifics for kstl: just some mid-high level clouds this forecast 
period. S-sely surface winds will strengthen late this morning and 
become swly. Swly surface winds will continue tonight and Saturday 
morning.
