SHORT TERM. (Through Late Friday Night) Issued at 243 PM CDT Thu Oct 28 2021

Stacked system over southeastern Missouri this afternoon will continue to slowly slide east then northeast over the next 24 to 36 hours. In the very near term, latest RAP40, CAMs as well as HREF ensembles, are indicating some weak instability over southeast portions of the forecast area, with surface based CAPEs around 250 J/kg. This coincides with the dry slot where some clearing has developed, so isolated storms are expected to develop in this area through 03z Friday before loss of daytime heating. Otherwise, several pieces of energy will rotate around the system with waves of showers and/or drizzle through Friday evening. With very moist low levels and light winds expect patchy fog across the region through daybreak on Friday.

With the slow movement of the system and plenty of moisture associated with it, skies will remain cloudy through Friday before gradually clearing out from the west late Friday night. This thick stratus deck will keep temperatures from fluctuating much with lows tonight and Friday night between 45 and 50 degrees and daytime highs only in the 50s on Friday.

LONG TERM. (Saturday through Next Thursday) Issued at 243 PM CDT Thu Oct 28 2021

The low pressure system currently over southern Missouri will be nearing the Mid-Atlantic by Saturday, giving our region a short break from the dreary weather. The next system will push a cold front into the CWA on Sunday. This front will stall, causing high temperatures to vary areawide. The northern half of the CWA will remain in the mid 50's, whereas our southernmost counties may reach the mid 60's. The frontal passage will be dry, only serving to dampen temperatures as it reinforces the northwest flow already in place. Surface high pressure will expand into the Plains behind this feature.

From here on, model certainty begins to diminish. A shortwave trough will cross over the area Monday, bringing the chance of precipitation. The timing, location, and intensity of this feature are all inconsistent in deterministic guidance. The most confidence in timing of arrival lies around 06z Tuesday. The push of the aforementioned surface high into the Midwest will introduce more dry air into the area and work to inhibit rain chances. The best chance for rain will be along the front where convergence and moisture will be most prevalent.

The surface high will continue to build into Missouri and Illinois Tuesday, shifting precipitation chances south. How far south depends on the positioning of the high, which varies between both deterministic models and ensembles. The NBM is still holding onto the small chance of light snow Tuesday night into early Wednesday morning. However, GEFS members as well as global models initialize either rain or no precipitation. Sounding data from the 12z run of the GDPS and GFS display the likelihood of rain. The atmosphere aloft in the northern CWA is too dry for snow, and the surface temperatures to the south are too warm. The chance for snow between Monday and Wednesday is unlikely but still nonzero.

The surface high continues its trek east Wednesday with precipitation only on its southern periphery. Again, the positioning of the high is uncertain, therefore so is the location of precipitation. For now, slight chance PoPs have been left in the southern CWA to address the uncertainty.

AVIATION. (For the 18z TAFs through 18z Friday Afternoon) Issued at 1235 PM CDT Thu Oct 28 2021

Stacked low system over southeastern Missouri will slowly move to the east during the forecast period. Despite dry slot currently rotating through region, IFR/LIFR ceilings will persist, though a brief period of MVFR ceilings is possible for the St. Louis metro area TAFs between 18z Thursday and 00z Friday. Otherwise, off and on showers/drizzle through the forecast period with patchy fog as well. East to northeast winds will veer to the north to northwest as the low moves away from the region. As it tracks to the east, winds will increase and become gusty, between 20 and 25 kts at times.
