NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
558 PM CST Friday Feb 5 2016 


Short term: (through late tonight) 
issued at 325 PM CST Fri Feb 5 2016 


A pair of vort maxes will approach the region tonight, spreading 
extensive mid/high cloudiness over the area. The northern vort Max 
is the weaker of the pair and eventually phases with the southern 
disturbance, although there is some model disagreement regarding how 
quickly this occurs. Latest runs of the rap point to a quicker 
phasing than shown by the local WRF or NAM, and the quicker timing 
looks reasonable based on recent satellite imagery and pv analyses. 
Quicker phasing means that the northern disturbance won't produce 
much lift over the County Warning Area and therefore there is much less chance of 
flurries or sprinkles given the already limited moisture. Overnight 
lows should be a few degrees warmer than yesterday due to extensive 
cloud cover and weak warm air advection at low levels behind a retreating surface 
high pressure center. 


Kanofsky 


Long term: (saturday through next friday) 
issued at 325 PM CST Fri Feb 5 2016 


An upper level trough will swing thru our region dry on Saturday, 
with forcing not strong enough and a column not moist enough, as the 
main storm center passes well to our south, and should produce 
nothing more than clouds that will decrease as the day wears on. 
Otherwise, SW winds left in its wake will result in an above average 
temp day, with maxes from the mid 40s to mid 50s favored, or at or 
above the higher mav MOS. 


A more direct hit from a decently strong upper level disturbance 
will occur late Sunday and into Sunday night, but will still be 
fighting a largely dry column. Have added low pops for most of our 
region for light rain for Sunday afternoon, and areas south and east 
of stl Metro heading into Sunday evening. 


This initial disturbance Sunday will also correspond to the leading 
edge of a brief shot of Arctic air that will begin later Sunday 
night and continue into Monday night, resulting in scattered snow 
showers over much of the region. Accums will be hard to nail down 
this far out and due to the nature of the pcpn, but could see spotty 
accums up to an inch from this event. Needless to say, the leading 
edge of the Arctic airmass will also be accompanied by strong gusty 
northwest winds, clouds, and stagnant daytime temps on Monday as cold air advection 
remains strong thru the day. 


Models are less clear, but it appears a second clipper-like system 
may drop down for the Tuesday night or Wednesday timeframe, but the 
signal is not enough, especially for this type of system, to place 
mentionable pops in the forecast just yet. 


Otherwise, northwest upper flow continues thru all of next week and will 
leave the door open for additional cold air intrusions, one of which 
is slated to drop down Thursday or Friday. 


Overall a period of mainly below average temps separated briefly by 
periods of above average temps, with little in the way of 
precipitation.

Aviation: (for the 00z tafs through 00z Saturday evening) 
issued at 546 PM CST Fri Feb 5 2016 


Expect dry and VFR conditions through the taf period. High 
pressure will move away from the area early tomorrow causing winds 
to pick up from the southwest during the day. 


Specifics for kstl: expect dry and VFR conditions through the taf 
period.
