Area forecast discussion...updated 
National Weather Service St Louis MO 
915 PM CDT Tue may 5 2015 


Update: 
issued at 910 PM CDT Tue may 5 2015 


Going fcst looks on track so just touched up the grids to account 
for the current trends. Shower activity continues to dsspt but has 
lingered a bit longer than originally anticipated with just a few 
lingering echoes southeast of the stl Metro area. Remnant cloud cover 
from earlier convection will drift north thru the evng as it 
continues to dsspt.

&& 


Short term: (through late tonight) 
issued at 250 PM CDT Tue may 5 2015 


Isolated to scattered afternoon rain showers/thunderstorms and rain should start to dissipate 
early tonight with the loss of diurnal heating. Overnight lows in 
the 60s across the County Warning Area will be fairly similar to last night. Winds 
will start to back and become more southerly overnight in response 
to a low pressure system which will be lifting from nm into the 
Central Plains. 


Kanofsky 


Long term: (wednesday through next tuesday) 
issued at 250 PM CDT Tue may 5 2015 


Southwest flow aloft can be expected with southerly surface flow 
thru the upcoming weekend. This nearly always alludes to above 
average temps and pcpn chances and it appears it will be no 
different this time around. 


Thanks to hi-height SW flow initially, upper level disturbances will 
deliver glancing blows to our region from the west and north 
Wednesday and Thursday, resulting in decent rain chances for a 
uin-cou axis but minimal chances (climo [30%] or below) elsewhere. 


The Heights start to edge downward and enable the train of upper 
level disturbances to start affecting more and more real estate over 
our region by Friday and into the weekend, and this will represent 
our best chances for widespread rain, where all areas will have 
above climo pops with many in likely category. This is not a huge 
change by any stretch from the previous forecast, however. 


The main upper level low that had been spinning over the 
southwestern Continental U.S. For much of this week is anticipated to bust 
loose into the plains by early next week and affect our region on 
Monday, giving US one more day of potentially wet wx. 


Finally by Tuesday a pattern change is in the works with northwest flow 
aloft in the wake of that main storm system exiting the SW Continental U.S.. 


Max temps thru Thursday are expected to be in the 80s with min temps 
in the 60s, with a gradual cooling trend from the west beginning 
Friday, but most locales in stl Metro and east should still break 80 
thru the weekend until early in the work week. 


A more definitive cooling trend is then expected to take hold on 
Tuesday and continue for a few days beyond.

Aviation: (for the 00z tafs through 00z Wednesday evening) 
issued at 544 PM CDT Tue may 5 2015 


The high based, diurnal cumulus clouds along with the widely 
scattered showers and thunderstorms should dissipate early this 
evening due to the loss of daytime heating. There may be a little 
mid-high level cloudiness for the remainder of the night into 
Wednesday morning. At least scattered cumulus clouds will develop 
again late Wednesday morning and afternoon with the best chance of 
showers/storms for the cou area. S-sely surface winds can be 
expected tonight with a sly surface wind on Wednesday. 


Specifics for kstl: looking at the latest radar trends it appears 
that the widely scattered showers/storms will not impact stl early 
this evening. This diurnal convective activity along with the 
high based cumulus clouds should dissipate later this evening with 
just a little mid-high level cloudiness for the remainder of the 
night into Wednesday morning. Diurnal cumulus clouds will develop 
again for late Wednesday morning and afternoon, but it appears 
that any showers/storms will remain west of stl. A weak S-sely 
surface wind can be expected tonight with a strengthening sly wind 
for Wednesday morning into the afternoon.
