NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
351 am CDT sun Apr 20 2014 


Short term: (through late this afternoon) 
issued at 341 am CDT sun Apr 20 2014 


Sunday will certainly feel like Spring, with a warm south breeze 
helping temperatures to climb into the mid 70s over southwest 
Illinois, and upper 70s to around 80 degrees across the remainder 
of the forecast area. While no precipitation is anticipated during 
the day today, mostly sunny skies in the morning will give way 
to increasing cloudcover from the west through the afternoon and 
evening hours. 


Jp 


Long term: (tonight through saturday) 
issued at 341 am CDT sun Apr 20 2014 


Sunday night looks to be dry across much of the forecast area, with 
models indicating a slower yet eastward progression of showers and 
thunderstorms from western Missouri associated with a southwest 
shortwave progged to move into western Missouri around 00z Monday. 
Current expectation is for precipitation to gradually overspread mid 
Missouri by around 09z, and the remainder of the forecast area 
during the day. Have gone with more thunder than previous forecast 
packages, especially Monday/Monday evening, given ample moisture 
convergence and frontogenetical forcing associated with the cold 
front moving through the forecast area during the afternoon and 
evening hours. The GFS, NAM, and local WRF are also indicating 
MUCAPE ahead of the front in the 1000-1200 j/kg range, and while 
severe weather isn't anticipated at this time, currently felt it 
prudent to up the mention of thunder for Monday/Monday evening given 
the instability present ahead of the advancing cold front. 


The cold front and associated precipitation should be well southeast 
of the area by Tuesday morning as the main trough axis shifts east 
of the Mississippi River valley and surface high pressure builds in 
to the region in the wake of the front. Thus, temperatures Tuesday 
will be cooler, though the cooldown will be short-lived as another 
ridge will build over the region and amplify by Wednesday in 
response to the deepening trough over the eastern Continental U.S. And a Lee 
trough/developing low pressure over the plains. The GFS, Gem, and 
European model (ecmwf) all continue to indicate the potential for some ridge-runner 
type storms to develop Wednesday/Wednesday afternoon, though the GFS 
and Gem keep any quantitative precipitation forecast just north of the forecast area Wednesday, with 
the European model (ecmwf) brushing light quantitative precipitation forecast over northeast Missouri and west 
central Illinois Wednesday afternoon and evening. Have maintained a 
slight chance for showers and thunderstorms over the northern tier 
of the forecast area on Wednesday to account for this. 


Late Wednesday night through Thursday night will be the next chance 
for widespread precipitation across the forecast area, as the 
aforementioned low developing over the North Plains begins to move 
eastward toward the Great Lakes, with an accompanying cold front 
progged to move through the middle Mississippi Valley. Have not 
made many changes to the going forecast at this time, given 
discrepancies in timing that remain between the GFS and ECMWF, the 
European model (ecmwf) continuing to be about 6 hours faster than the GFS. Feel that 
the broad-brushed chance pops, with likely pops Thursday for 
portions of the area should be sufficient at this time. Model 
differences aside, the cold front should be exiting the area to the 
east by Friday morning. Do not expect temperatures to drop much on 
Friday in the wake of the cold front, as westerly flow remains at 
low levels, though as the low pressure system moves toward the 
Great Lakes and another ridge begins to take shape over the plains, 
Friday night and Saturday should be cooler under northwest flow, and 
thus have maintained the cooler trend with temperatures at the end 
of the period.
