NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
325 PM CDT Mon Jul 28 2014 


Short term: (through late tonight) 
issued at 325 PM CDT Mon Jul 28 2014 


Sprawling ridge of high pressure extending from Saskatchewan Canada 
southeast through the Great Plains and into the Midwest. Extensive 
area of diurnal stratocumulus has erupted again today, but this 
should dissipate quickly this evening. Expect a mostly clear night 
with unseasonably cool temperatures from the mid 50s to around 60 in 
the stl Metro area. 


Carney 


Long term: (tuesday through next monday) 
issued at 325 PM CDT Mon Jul 28 2014 


A deep longwave upper trough will dominate eastern North America thru 
the end of the week, resulting in northwest flow over our region. Some 
loosening up of this pattern looks to occur for early next week, but 
the overall theme remains the same: an extended period of below 
normal temps should be the result with maxes from 80-85 each day 
with mins in the 50s and low 60s. Given how this July has not been 
that hot at all, some of our climo sites, such as uin and cou, could 
be in line for a top 5 coolest July on record. 


Weak upper level disturbances will trickle down in the northwest flow the 
next several days, and with marginal levels of moisture and some 
favorable lo level instability, low-topped rain showers or even thunderstorms and rain will be 
possible in the afternoon the next couple of days. See the activity 
in northwest Iowa currently for reference. It will be a very low pop 
though, with most not receiving anything. By Thursday, a bit better 
moisture but still not great, will allow somewhat deeper convection 
to occur and this setup will continue thru the end of the week with 
afternoon chances each day. A drier setup looks set for next week 
though.

Aviation: (for the 18z tafs through 18z Tuesday afternoon) 
issued at 1206 PM CDT Mon Jul 28 2014 


Hi pressure will control the weather through Tuesday. VFR flight 
conditions and northwest flow will prevail. Expect this 
afternoon's ceilings to clear out by early this evening. Scattered 
clouds will likely return Tuesday. 


Specifics for kstl: 


VFR flight conditions and northwest flow is expected to continue 
through Tuesday. Expect this afternoon's ceilings to dissipate by 
early evening. Scattered clouds will likely return Tuesday.
