NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
542 PM CST Wed Nov 26 2014 


Short term: (through late tonight) 
issued at 351 PM CST Wed Nov 26 2014 


Clipper system continues to impact our forecast area at this time. 


At 21z...a low pressure center was located in northeast MO and 
was moving slowly to the southeast. A warm front extended to the 
south-southeast of this low pressure area into east-central MO--just 
west of the stl Metro area--where temps have risen into the upper 
30s and low 40s. The cold front associated with this system is 
gaining on the warm front and was now located from this low pressure 
area and to the south into central MO. Temps ahead/east of the warm 
front have remained in the low-mid 30s. An area of precipitation 
extended in a band on the Illinois side of the river mostly. Nearly all of 
this precipitation was snow. Drizzle has developed on the backside 
of this main band and into the vicinity of what is beginning to be 
an occluded front, as the cold front catches the warm. 


The low pressure in northeast MO is occluding with all anticipation 
that a new triple point will develop over Tennessee this evening. In the 
meantime, the front over our region will become occluded as well and 
simply a wind shift line and focus for drizzle. 


Temps near the MS river and Illinois will stall this evening and then 
slowly fall, while a more normal diurnal trend will be seen for 
central MO and southeast MO. Min temps tonight will strongly favor 
the higher met MOS values with low clouds expected to stick around 
all night. 


The precipitation band is expected to soon stall over in Illinois and 
gradually weaken this evening as the new focus shifts well to the 
southeast for the overnight. Leftover diurnally generated scattered 
showers...mostly snow by this point...will wander into the areas 
where the main pcpn band has vacated along with patchy drizzle 
associated with the occluded front moving thru. Temps may be cold 
enough for some fzdz to result as well. 


Additional snow accums will be minimal...with up to an inch extra in 
southwest Illinois. Icing potential will need to be watched carefully 
with models and radar not picking up on this too well yet but 
scenario does favor drizzle thru the evening.

Long term: (thursday through next wednesday) 
issued at 351 PM CST Wed Nov 26 2014 


Ridge of high pressure to move into the region on Thanksgiving with 
colder temperatures. Clouds will be slow to clear out so temps to 
only rise into the mid 20s to around 40. 


Another cold night Thursday night with lows in the 20s. Then surface 
ridge moves to the east allowing southerly winds to return and 
become gusty on Friday. So highs will be near normal in the mid 40s 
to mid 50s. 


Warmer weather to persist through the weekend with highs in the mid 
50s to mid 60s on Saturday and lows Saturday night in the low 40s to 
low 50s. Models still bring a cold front into region during the day 
on Sunday. High temp forecast to be tricky depending on timing of 
this frontal boundary. For now have highs in the upper 40s far north 
to the mid 60s far south. Otherwise, low level moisture will be on 
the increase ahead of this front so could see some rain across 
southern half of forecast area Sunday through Monday with it mixing 
with or changing over to snow at times. Lows Sunday night will be in 
the upper teens to mid 30s. Highs on Monday will be in the low 30s 
to low 40s. 


Weak surface ridge to build in Monday night and Tuesday. So will see 
dry conditions with lows Monday night in the low 20s to low 30s and 
highs on Tuesday in the 40s. 


Beyond that extended models have differing solutions with European model (ecmwf) a 
bit faster with next frontal passage and drier vs. GFS which is 
slower and much wetter solution. For now went with a blend, have 
slight chance pops Tuesday night and chance pops on Wednesday. 
Temperatures to be near freezing Tuesday night in northern portions 
of forecast area so could see a mix of rain and snow. Otherwise, 
rain possible for mid week next week.

Aviation: (for the 00z tafs through 00z Thursday evening) 
issued at 531 PM CST Wed Nov 26 2014 


Surface low located midway between kcou and kstl at 23z will move 
southeastward tonight into the Tennessee Valley region. Its initial 
passage to the east this evening will actually bring warmer air 
briefly into the St. Louis region for a short period early this 
evening before increasing northwest winds bring in more colder 
air. What this means for the St. Louis area terminals is that they 
could see rain, snow, and a mix this evening. Flight conditions 
will remain IFR tonight where they currently exist at KUIN and 
kstl/ksus/kcps, while they should lower to IFR at uin. Sometime 
during the period from late tonight into mid Thursday morning 
there should be improvement to MVFR, and to VFR from late morning 
into the afternoon. 


Specifics for kstl: 


IFR flight conditions will persist through early Thursday morning 
with imrovement to MVFR after 12z, and to VFR around midday. A mix 
of precipitation types are expected this evening which could be 
all rain, all snow, or a mix of rain/snow.
