Area Forecast Discussion National Weather Service Saint Louis MO 155 PM CST Fri Jan 28 2022

SHORT TERM. (Through Late Saturday Night) Issued at 149 PM CST Fri Jan 28 2022

A surface high has moved into the region behind yesterday's cold front and this morning's light snow, driving cloud cover from the area. Winds will become light and variable overnight while the high slides over the region, and combined with the clear sky, allowing temperatures to cool effectively overnight. Lows tonight will be chilly, dropping into the single digits across much of the forecast area.

Despite the chilly start, temperatures will warm effectively on Saturday under the influence of the advancing low-level ridge and subsequent warm air advection and clear sky. Areas across central Missouri will warm the most, being positioned closest to the ridge. Through the afternoon the low-level ridge will begin to push off to the east out of the forecast area while a surface low slides southeast from the Dakotas into the mid-Mississippi Valley. It's attendant cold front will slide through the region Saturday night into Sunday. Conditions will be dry and forcing weak along the front, so impacts associated with this cold front will be limited to a wind shift at the surface. Temperatures will not be impacted very much as the bulk of the cooler air will stay north of our forecast area.

MRM

LONG TERM. (Sunday through Next Friday) Issued at 149 PM CST Fri Jan 28 2022

By Sunday the forecast area will be positioned in northwest flow through the mid-levels as a trough and nor'easter pushes out of New England, and a ridge builds into the western CONUS. At the surface, benign conditions will continue as a surface high pushes quickly across the forecast area, keeping the sky clear and temperatures near normal. Over the first half of the work week, a shortwave trough will pass through northwesterly mid-level flow, swinging through the mid-Mississippi Valley. Mirrored at the surface, a low will slide across the US-Canada border into the Great Lakes region by Tuesday. Its attendant cold front will drag through the forecast area during the day Tuesday. The combination of frontogenetical and isentropic lift as well as warm air advection along the southwesterly low-level flow will produce widespread rain across the region into Tuesday night. Initially warm temperatures will cool below freezing behind the front, and if precipitation overrides the front and lingers in its wake, it could fall as some kind of wintry precipitation.

While this initial round of precipitation is moving through the region, another shortwave trough will be coming onshore over the western CONUS. This trough is expected to deepen as it swings into the region Wednesday night into Thursday. In response to the ejecting trough, isentropic lift and warm air advection will strengthen and continue fueling precipitation through the day Wednesday and into Wednesday evening. There is a 10 degree spread between the 25th/75th percentiles for Wednesday's high temperatures, crossing the freezing line, which will impact what kind of precipitation makes it to the ground across the CWA. A surface low sliding across the southern US will lift northeastward through the lower to mid-Mississippi Valley Wednesday into Thursday in concert with the movement of the mid-level trough, reinforcing lift and moisture to continue precipitation across the region. A strong ridge is expected to push into the region Thursday to usher precipitation out of the region and a cold air mass into the area in it's wake.

Confidence is high that a strong winter system will move through the mid-Mississippi Valley during the middle portion of next week and produce measurable snowfall. The NBM 25th percentile is now producing light snow across much of the mid-Mississippi Valley and most GEFS and ECMWF members indicate at least measurable snowfall. But there is great uncertainty in when rain will transition to snow, where this will occur, and where the heaviest snow will fall. Shifts in the southeastward progression of the cold front, depth of the post-frontal air mass, and the track of the system will greatly impact how much precipitation and snow is able to fall.

MRM

AVIATION. (For the 18z TAFs through 18z Saturday Afternoon) Issued at 1119 AM CST Fri Jan 28 2022

Light snow and flurries are moving out of the St. Louis metro terminals having already exited the mid-Missouri terminals and KUIN earlier this morning. VFR flight conditions will persist through the TAF period under clearing skies as a surface high moves into the region behind the snow. Northwesterly winds will be sustained between 10-15 knots today, gusting into the mid 20s through the afternoon. Winds will become light and variable overnight as the center of the high moves across the terminals.
