Area forecast discussion...updated 
National Weather Service St Louis MO 
752 PM CDT Fri may 22 2015 


Update: 
issued at 752 PM CDT Fri may 22 2015 


Lots of echo on the radar mosaic this evening, but much of it is 
deceptive, only showing up when the radar beam is at a certain 
level--instead hitting the mid level clouds. However, the very 
back edge of this echo in western MO is indeed hitting the ground 
and has even measured .01" in a few places with kszl the latest to 
report sprinkles. These scattered showers are the product of 
moisture convergence and being at the Vanguard of the better 
h850 moisture and further being aided somewhat by the eastern 
extension of broadscale lift that is centered over the mid-MO 
River Valley. 


This area is expected to advance east-NE and NE over the course of 
this evening but will also move away from some of the better 
moisture which spawned its early successes. Have added sprinkles 
to the central and northeast MO forecast for mid and late evening 
but do not expect any measurement with it expected to weaken some. 
For now, have kept overnight dry with further weakening currently 
expected. 


Otherwise, temps on track for upper 50s and lower 60s for mins 
thanks to mostly cloudy skies, which places it at or slightly 
above the higher MOS values.

Short term: (through late tonight) 
issued at 339 PM CDT Fri may 22 2015 


Upper level ridge is amplifying over the mid-Mississippi Valley as 
the trof over the western Continental U.S. Deepens. Some of the last vestiges 
of the plains convection may make it into the area during the 
evening, but the air overhead is quite dry and the upper ridge 
should be providing some decent subsidence. Expect little more than 
a light shower or sprinkles if any of the precip actually makes it. 
Otherwise, it should be a quiet night. Lows should be much warmer 
than this morning's with increasing mid and high clouds and light 
south-southeast flow. Mav/met numbers are within 1-2 degrees of 
each other, and I see no reason to deviate at this time.

Long term: (saturday through next friday) 
issued at 339 PM CDT Fri may 22 2015 


Upper level ridge continues to amplify through Saturday which should 
keep a damper on convection across our area. Main threat for rain 
should stay over the plains into western Missouri. The ridge starts 
translating east, putting the Mississippi Valley in deep southwest 
flow Saturday night. This will gradually increase our rain chances 
as shortwaves ripple by. Looks like several waves of showers and 
thunderstorms will move through the area late Saturday night through 
Monday. Potential for heaviest rain still looks to be across 
central and northeast Missouri into west central Illinois. Medium 
range guidance is in pretty good agreement that the primary 
shortwave will open up and be pulled northeast late Monday, but a 
secondary wave will move across the Great Plains Monday night into 
Tuesday. While the chance for persistent rain will decrease as the 
primary wave moves northeast, the secondary wave will likely produce 
at least scattered showers and thunderstorms as it moves across the 
area Tuesday into Wednesday. The remainder of the week continues to 
look warm with a chance of thunderstorms as we sit in southwest flow 
aloft. Temperatures look to be as much as 10 degrees above normal 
in the mid 80s.

Aviation: (for the 00z tafs through 00z Saturday evening) 
issued at 546 PM CDT Fri may 22 2015 


Mainly just VFR, mid-high level cloudiness through the period. 
Could not rule out a brief sprinkle from mid level clouds. Light 
surface winds tonight will become sely on Saturday as the surface 
ridge over our region shifts well east of the area. 


Specifics for kstl: VFR, mid-high level clouds through the 
period. The surface wind will become light early this evening, 
then strengthen to around 10 kts from a sely direction by Saturday 
afternoon.
