Area forecast discussion, Jan 10, 5:49 AM CST, 3 hours 51 minutes before
Area Forecast Discussion...Updated Aviation
National Weather Service Saint Louis MO
549 AM CST Fri Jan 10 2020
.SHORT TERM... (Through Late Saturday Night)
Issued at 350 AM CST Fri Jan 10 2020
Early this morning, an upper longwave TROF existed over the western
CONUS, resulting in SW flow aloft over our region. The strong storm
system that has been the subject of much interest to our forecast
has come onshore, with the core of it moving through the Mexican
state of Sonora. Ahead of this storm system, several weaker upper
level impulses were being kicked out ahead of it, through much of
the Lower-Mid Mississippi and Lower Ohio River Valleys. These
impulses were operating in a broad WAA regime with rich moisture
through the column, with PWs in excess of 1 inch. At the surface, a
cold front extended from western Illinois to near Quincy, through
northeast and into west-central Missouri. Numerous showers and a few
thunderstorms had developed south of the surface boundary and have
affected these areas for much of the night, with rainfall estimates
for most places between a one half and one inch. A few pockets
appear to have received as much as 2 inches. Temperatures south of
the front were quite warm for this time of year with readings in the
50s, with temperatures falling off into the upper 30s and lower 40s
behind the front in northeast and north-central Missouri.
(Today)
The center of the main storm system will begin to lift northeastward
today and into western Texas by early this evening, resulting in a
slight backing of flow aloft to more S-SW. This, in turn, will
result in the surface front becoming quasi-stationary. The current
main axis of showers and a few thunderstorms is expected to persist
through this morning for areas near and south and east of the STL
metro area with more scattered or lesser coverage for areas to the
north and west. With a fresh wave of upper level impulses being
thrown our way towards sunset this afternoon, look for coverage of
showers to fill in across the entire forecast area, especially in
light of the backed flow aloft and hurling of even juicier Gulf of
Mexico air towards our region. Temperature rises will be driven
largely by dewpoint rises south of the front, and with dewpoints
expected to rise to close to 60 degrees for many of these areas,
look for max temps into the lower 60s. North of the front, little
movement of temps is expected with lower 40s, yet still too warm to
worry about wintry precipitation.
(Tonight)
The center of the main storm system will then track into central
Oklahoma tonight and the strong lift just ahead of it will develop
and drive a surface wave into southern IL that will drag the surface
cold front across much of the forecast area. The richest moisture
of the event will move through our region at this time with PWs
approaching 1.5" and surface dewpoints just shy of 60F. The advance
of the cold front through our region is expected to develop a line
of thunderstorms that will move through primarily from 01z in
central MO to 06z in the STL metro area to 09z in southern IL. The
line of storms will be capable of isolated damaging wind gusts and
possibly tornadoes as it moves through in what will be a high shear,
low instability environment and where it can be surface based, the
severe threat will exist. There is a lesser threat for large hail
with most hail likely being sub-severe in our area.
The advance of the cold front will drag in much colder air at the
surface behind the line of storms, but with warm air aloft much
slower to recede due to the wrapped up nature of the storm system
and that the main storm center will still be upstream, look for rain
to transition to freezing rain and sleet for areas of northeast MO
and this wintry precipitation is expected to advance into central MO
and west-central IL by sunrise where surface temps fall to 32F or
below.
(Saturday)
The storm center is then expected to track to near the Mid-
Mississippi River by sunset Saturday. There is increasing evidence
of a break in the precipitation occurring some distance behind the
surface cold front late Friday night until onset of another round of
precipitation occurs with the advent of the main storm center later
on Saturday morning. During this interlude, precipitation may
continue but will probably be more of a light drizzle or spotty
light precipitation associated with some loss of cloud ice, and
therefore favors a more prolonged period of freezing rain and sleet
for areas behind the front where temperatures have already dropped
below 32F: namely northeast and central MO and west-central IL.
Cloud ice will then return by late Saturday morning or midday
Saturday to many areas and at this point, precipitation for
northeast and central MO and west-central IL should transition to
all snow with snow then advancing into the STL metro area and
southeast MO by mid-late Saturday afternoon as temps fall through
the 30s there. Edged PoPs a bit higher Saturday night with good
agreement amongst guidance of placement of main upper system still
over or upstream of much of the forecast area at 00z/Sun with an
exit of snow then expected by midnight Saturday night.
(Summary)
Snow totals have been cut significantly for northeast MO where loss
of cloud ice between main precipitation episodes occurs and keeps
freezing rain and sleet. Snow totals of 2-3" now expected for the
previous Watch area with up to a third of an inch of sleet and
between two and three tenths of an inch of ice from freezing rain.
This all adds up to needing a Warning.
Elsewhere in west-central IL and northeast and central MO to the far
western reaches of the STL Metro area, an Advisory will be issued
primarily for ice from freezing rain accretion and some limited snow
accums of 1-2" and up to a tenth of an inch of sleet.
For most of the STL metro area and areas south and east, no
headlines for now with a dusting of snow expected, minimal sleet and
little to no ice.
Rainfall totals still look stout with much of the rainfall occurring
tonight, with 2 to 4 inches of additional rainfall expected. The
existing Flash Flood Watch looks good and no changes made.
TES
.LONG TERM... (Sunday through Thursday)
Issued at 350 AM CST Fri Jan 10 2020
Above normal temps look to continue through Wednesday with periodic
light precipitation possibilities with colder air attempting to work
in late week.
TES
&&
.AVIATION... (For the 12z TAFs through 12z Saturday Morning)
Issued at 548 AM CST Fri Jan 10 2020
Predominantly IFR conditions and showers will prevail at the TAF
sites for much of the valid period. Best chances for thunder are
expected to be late this afternoon and tonight. Where
thunderstorms were targeted to prevail tonight, there is the
additional possibility they could be accompanied by stronger wind
gusts. A 40kt or higher low level jet will edge into the STL metro
sites tonight but it appears that enough convection will exist to
overrule and assume presence of LLWS without an explicit mention.
Otherwise, look for south winds less than 10kts to strengthen
late this afternoon and evening and then shift sharply from the
north with cold FROPA with gusts to 30kts. Colder air spilling in
behind front and slackening off of precipitation intensity should
result in SHRA becoming FZDZ heading into Saturday morning for
KCOU and KUIN.
SPECIFICS FOR KSTL: No wintry precipitation is expected for the
entire valid period.
