NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
430 am CST Thu Mar 5 2015 


Short term: (through late this afternoon) 
issued at 344 am CST Thu Mar 5 2015 


An upper level trough axis extends from Minnesota to central Kansas early this 
morning with a west-SW flow resulting over our region. Canadian high 
pressure was centered over the mid-MO River Valley. The primary 
cold front is well to our south, near the Gulf of Mexico coastline, 
and there appears to be a weak secondary cold front pushing thru 
northern MO and central Illinois now as evidenced by some pressure rises, 
a lull in the winds, and a reinforcing shot of cold air advection. Some weak lift, 
either from this or from something immediately following the front, 
also seems responsible for additional clouds and patchy light snow 
in Iowa. Temps were in the teens and lower 20s across our region with 
no precipitation (for the moment). 


The upper level trough axis is expected to swing thru by early this 
afternoon leaving behind northwest flow aloft in its wake. The weak lift, 
which seems to be shown best on the GFS model, tracks southeastward 
towards the Quincy area this morning before its various component 
parts split apart by midday off to our east and southeast. The 
atmospheric column is very dry already and so we do not expect much 
more than scattered flurries for some areas in northeast MO and into 
west-central IL, with an isolated heavier snow shower possible but 
the coverage of which is not significant enough to account for in 
the forecast at this time as there are some doubts as to how well 
even the scattered flurries will hold up as they try to move 
southeast. Either way, it looks to all be gone by early afternoon. 
This area of lift will also bring some extra clouds into the area as 
well and delay our full clearing until later in the day. 


Otherwise, it will be a very cold day today, with Max temps not 
expected to exceed the mid 20s, with readings remaining in the teens 
for many areas north and northeast of stl Metro. A MOS blend was 
used for most sites. This will result in temps being about 30 
degrees below the norm for this time of year. 


Tes 


Long term: (tonight through wednesday) 
issued at 344 am CST Thu Mar 5 2015 


Tonight will be unseasonably cold again, particularly across 
southeast MO and southwest Illinois near the surface ridge axis with good 
radiational cooling expected. Will go below MOS temperature 
guidance, especially in areas with snow cover. Temperatures across 
northeast and central MO will fall this evening, but should become 
nearly steady or rise slightly late tonight as surface winds become 
southerly on the west or northwest side of the surface ridge, and as 
low level warm air advection increases over this area. A northwest 
flow shortwave will move southeastward through northeast MO and west 
central Illinois late tonight. There may be a little cloud cover ahead of 
this feature, but it will be too dry for any precipitation. Friday 
will be the start of a warming trend as surface south-southwesterly 
flow becomes established across the area. The models shift the zero 
degree c 850 mb isotherm eastward to the Mississippi River by 00z 
Saturday. Temperatures by Friday night should be near normal for 
early March, and eventually above normal by Saturday. The NAM model 
generates some very light qpf Saturday night across Illinois ahead of a 
northwest flow shortwave, but this is likely more of a reflection of 
boundary layer moisture and possible low level cloudiness and not 
likely any light precipitation. A weak and dissipating cold front 
will drop southeastward into our area Saturday night. Little if 
any cooling is expected behind the front, maybe a few degrees cooler 
across northeast MO and west central IL, but most areas will 
continue to have above normal temperatures for the remainder of the 
weekend. The dry and tranquil weather pattern will continue for the 
next work week with surface ridging across our area on Monday. Even 
warmer temperatures are expected for Tuesday and Wednesday with any 
precipitation remaining south and southeast of our forecast area 
ahead of a southern stream upper level trough and assoociated 
surface low.

Aviation: (for the 12z tafs through 12z Friday morning) 
issued at 430 am CST Thu Mar 5 2015 


VFR conditions will prevail at the taf sites thru much of the 
valid period. Only concern is a small stubborn area of low cigs 
that continues to snake its way down into northeast MO. There are 
also some flurries in this area. Low level flow would encourage 
this area of clouds/flurries to move south-southeast but the weak lift that 
seems to have generated it in the first place looks set to weaken 
with time and so there is some measure of doubt how far south this 
will go. Will add some scattered clouds in and watch closely the 
next few hours. Otherwise, look for northerly surface winds to 
become light and variable by Sundown and then from the southeast later 
tonight. 


Specifics for kstl: VFR thru the period. Only questionable item is 
how well will small area of low cigs and some flurries hold 
together as they are expected to drop south-southeast thru eastern-central MO. 
Will maintain scattered cloud coverage for now and continue to 
monitor considering what generated them in the first place is 
expected to weaken. Otherwise, winds will be the main driver of 
new taf line groups as they go from north to light to southeast.
