NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1016 PM CDT Mon Mar 30 2015 


Update: 
issued at 935 PM CDT Mon Mar 30 2015 


Should be a relatively mild late March night across the region 
thanks to a fairly decent pressure gradient that will maintain 
southwest to west winds throughout the night. 


Going forecast trends are still looking good. 


Truett 


&& 


Short term: (through late tonight) 
issued at 350 PM CDT Mon Mar 30 2015 


South to southwest flow will prevail tonight ahead of a weak cold 
front which will move through Tuesday. Dry atmosphere will provide 
a mostly clear sky...with perhaps a few cirrus clouds. Temperatures 
look to stay near or just above climatological normals due to the 
warm southwest winds. Used a blend of guidance for lows, but leaned 
toward some of the warmer members of the ensemble. 


Carney 


Long term: (tuesday through next monday) 
issued at 350 PM CDT Mon Mar 30 2015 


The forecast over this period can be broken down into three 
segments, all primarily based off the upper flow pattern. 


Through Tuesday night, a northwest flow will prevail over our 
region, delivering quiet wx, thanks to dry air and little in the way 
of any forcing mechanisms. A weak cold front will move thru during 
the day on Tuesday, but both the associated warm air advection ahead of it, and its 
expected position when it might be able to gain some leverage from 
the heating of the day for some surface based convection are not 
favorable for any mention of pcpn at this time. Have continued the 
dry forecast from the previous package. 


The air following the cold front will not be much different than the 
one ahead of it, and so despite northwest winds for much of Tuesday for 
most areas, temps are expected to follow persistence or a bit above. 


The upper flow will then back to the west-SW by late Wednesday and 
continue into Friday night, signalling a more active wx pattern to 
close the work week. The old front from Tuesday will be buckling 
northward as a warm front on Wednesday, but the timing looks to be a 
bit slower than it did 24hrs ago. Given the significant increase of 
moisture thru the column that will accompany this warm front, its 
delay will still mean Worth a small pop mention for the afternoon 
and evening but over a more western area than 24hrs ago. 


More significant forcing will move in late Wednesday night and 
continue into Thursday evening as a stronger cold front than the one 
on Tuesday drops down and will result in periods of showers and 
thunderstorms. Another shot of forcing, mostly frontogenetical and 
Post-frontal, will then move in on Friday providing mostly rain with 
any thunder confined to southern MO and Illinois. 


A warm day is expected for Wednesday, and potentially into Thursday 
depending on the exact timing of the rain and front, with much 
cooler temps than expected on Friday behind the front with rain. 


A period of quieter wx is then expected for the weekend with northwest flow 
restored by Saturday morning and drier air moving in. Temps will be 
quick to rebound, after a cool Saturday, towards normal on Sunday as 
surface winds turn from the south. 


Southwest upper flow could occur already by Monday next week with 
the normal accompanying rain chances, but some model disagreement on 
timing here so went conservative with pops and leaned towards climo 
values.

Aviation: (for the 06z tafs through 06z Tuesday night) 
issued at 1007 PM CDT Mon Mar 30 2015 


VFR conditions expected through this taf period. Weak surface 
front will approach KUIN around 10z and the kstl Metro taf sites 
by around 14z. Low level wind shear will exist at all sites through the night 
until frontal passage. A wind shift to light northerly surface winds 
will accompany the front but little else in sensible weather. 


Specifics for kstl: VFR conditions other than low level wind shear until around 
14z when a weak cold front will pass through. Surface winds will 
become light northerly behind the front.
