NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1134 PM CDT Mon Apr 20 2015 


Short term: (through late tonight) 
issued at 230 PM CDT Mon Apr 20 2015 


The isolated showers/sprinkles should diminish by this evening as 
shortwave exits region so do not have in grids. As for cloud cover 
and winds, to diminish as well with skies clearing out and winds 
becoming west to southwest around 10 kts. Colder temps tonight with 
lows a bit below normal in the upper 30s to low 40s. 


Byrd 


Long term: (tuesday through next monday) 
issued at 230 PM CDT Mon Apr 20 2015 


Upper level trof/low over the center of the Continental U.S. Will continue 
to deepen as it moves east toward New England this week. A pair of 
shortwaves embedded in the resultant northwest flow overhead will 
bring chances of showers to at least the southern County Warning Area Tuesday 
afternoon through Wednesday morning. 


A west-southwest surface wind on Tuesday will help temperatures warm 
toward normal values for afternoon highs. Believe fuel moisture will 
remain too high to have any true fire weather concerns despite the 
warmer temperatures, low relative humidity, and gusty wind expected 
across the northern County Warning Area. The second shortwave will be accompanied by 
a cold front that will descend across the County Warning Area Tuesday night. Below 
normal temperatures are expected on Wednesday and Wednesday night 
and wouldn't be surprised if we eventually have to mention some 
frost for parts of the County Warning Area Thursday morning with temperatures 
dipping into the middle 30s. 


The northwest flow aloft will relax by Friday as heights begin to 
rise in response to the next approaching storm system with Pacific 
origins. Temperatures moderate some with highs back into the 60s 
on Thursday and Friday. Both the GFS and ecwmf depict a wet 
beginning to next weekend as a low pressure system moves from the 
Central Plains to the southeast. Can't rule out rain developing as 
early as Friday, but all indications are that the heaviest rain 
will fall Friday night into Saturday morning. Location will depend 
on where the best moisture convergence sets up, but at this point 
the models are suggesting the I-70 corridor has the potential to 
see an inch of rain. The rain should come to an end from north to 
south on Saturday afternoon as a surface ridge builds into the 
Midwest behind the storm system.

Aviation: (for the 06z tafs through 06z Tuesday night) 
issued at 1129 PM CDT Mon Apr 20 2015 


VFR through the period. Initially west-southwest winds will become 
westerly and increase by mid-morning with 20-30kt wind gusts 
expected for most of the day. Winds then decrease quickly after 
sunset. A cold front will move through the terminals late in the 
taf period and cause winds to become northwesterly. A few showers 
could skirt the I-70 corridor but most precipitation should remain 
south of the terminals.
