NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
608 am CST Tue Jan 27 2015 


Short term: (through late this afternoon) 
issued at 325 am CST Tue Jan 27 2015 


Satellite data at 08z showed the backedge of an area of clouds near 
the MS river breaking apart, but a new batch of clouds was already 
oozing southward from northeast Illinois and southeast Iowa. To the west, 
skies were clear, with cloudy skies covering much of our region east 
of the MS river. Temps were mild for late at night in late January, 
with readings in the 30s. Otherwise, northwest flow prevailed aloft with 
northwest winds also at the surface, thanks to an area of weak low pressure 
to the east and a weak ridge of high pressure to the west. 


No upper level disturbances or fronts are expected today with weak 
high pressure insteady building into the area. With a dry 
atmospheric column, the result will be dry wx. 


The main forecast problem will be clouds and their impact on temps. 
Flow at cloud level is expected to be out of the north this morning 
with a transition to negligible wind flow in the afternoon as the 
ridge builds in. Even though the backedge of the clouds near the MS 
river has collapsed, a new batch of clouds further to the north is 
expected to drop south into our region and create a new backedge to 
the cloud shield near the MS river again. The afternoon should 
feature some retreat of the cloud edge back to the east again as 
weak subsidence from the high pressure ridge moves in. Some 
question on whether or not the surviving clouds to the east will get 
moved back to the west if the ridge catches up and passes it too 
fast tonight. 


Max temps were forecast strongly favoring the lower met MOS numbers 
in much of southwest IL, with a MOS blend for the MS river region 
and Max temps at or slightly above the higher mav MOS for central 
MO. 


Tes 


Long term: (tonight through monday) 
issued at 325 am CST Tue Jan 27 2015 


(tonight through thursday) 


Main focus thru the period is temps with little in the way of 
precip. 


Mdls are generally in good agreement thru the period. However, some 
differences emerge late in the period regarding the speed and depth 
of the approaching trof. Mdls have come into better agreement with 
thermal profiles. Have trended slightly cooler tonight with clouds 
expected to clear out of the region for at least a portion of the 
night. No changes to temps for Wed. While latest mdl guidance 
suggests much of the region is not expected to mix above 950 mb, 
mdls have struggled to warm fast enuf with these types of systems 
lately. Heights lower quickly as the sfc ridge settles over the area 
and have trended cooler late in the period. 


Only precip expected is light precip associated with the system late 
Wed night into thurs morning. With such a strong S/W associated with 
this system, enuf cold air my push in behind the system that the 
precip may be snow. However, will keep p-types as rain for now until 
mdls come into better agreement with precip placement and thermal 
profiles with the precip. 


(Friday through monday) 


As the sfc ridge remains in control thru the remainder of the week, 
temps remain cooler ahead of the next approaching system. Focus 
quickly turns to this system as mdl solns have finally come into 
better agreement and are finally more consistent from cycle to 
cycle. The leading S/W ejects into the srn plains and spread precip 
across the region on Sat as the sfc low develops ahead of the main 
trof. Mdl solns are currently in very good agreement, tho some 
differences in timing continue. Current track of this system shud 
bring snow to at least portions of the County Warning Area while. This system will 
likely shift as it approaches and will be one to monitor. Much 
colder air will move into the region behind this system as the 
Arctic sfc ridge builds into the area.

Aviation: (for the 12z tafs through 12z Wednesday morning) 
issued at 608 am CST Tue Jan 27 2015 


Low VFR or MVFR cigs can be expected for most of the taf sites 
save cou thru at least late afternoon. A high pressure ridge 
will build in late in the day and if these clouds do not break up 
or push east sufficiently, the east winds that will develop as the 
ridge moves thru may keep the clouds around for a lot longer and 
something to be watched for later in the day. Otherwise, VFR is 
forecast for tonight. 


Specifics for kstl: low VFR to MVFR cigs are expected for most of 
the time thru at least late afternoon with clearing and VFR for 
tonight. May see a forecast problem develop if the high pressure 
ridge building in from the northwest can push thru fast enough 
before the clouds exit which may trap them thru the night.
