Area Forecast Discussion . Updated Aviation National Weather Service Saint Louis MO 528 PM CST Thu Mar 4 2021
SHORT TERM. (Through Late Friday Night) Issued at 158 PM CST Thu Mar 4 2021
A weak and dry backdoor type cold front continued to drop slowly southwestward through western and southern portions of the forecast area this afternoon with a surface ridge centered over WI. Unseasonably warm conditions again this afternoon across central and southeast MO with cooler highs across west central and southwest IL. This trend will continue tonight with the coldest lows across northeast MO and west central and southwest IL as the surface ridge in WI builds into eastern MO and southern IL. An upper level low over CO this afternoon will move into OK late tonight and into AR Friday afternoon as it opens up and weakens. The models including the CAMs have showers across southwestern MO on Friday, but keep the measurable precipitation southwest of our forecast area. Could not rule out a few sprinkles Friday afternoon, from Moniteau to Reynolds county in central and southeast MO. There will be more cloud cover along with lower upper level heights which will result in cooler high temperatures on Friday, albeit still slightly above normal.

LONG TERM. (Saturday through Next Thursday) Issued at 158 PM CST Thu Mar 4 2021
A gradual warming trend will begin Saturday afternoon and continue into the next work week as an upper level ridge shifts eastward into MO by Sunday, and as the surface wind becomes south- southwesterly by Sunday as well as the surface ridge shifts well east of the region. By Monday highs will be around 15 degrees above normal. Nighttime lows will also be warmer with rising surface dew points as persistent south-southwesterly low level flow begins to bring increasing low level Gulf moisture into our area. A chance of showers along with a few storms can be expected by Wednesday and Wednesday night due to low-mid level warm air advection ahead of southwest flow shortwaves, and as a cold front begins to approach our area. This cold front will drop slowly southeastward into our forecast area by Thursday, although the deterministic models and ensemble means do have some timing differences with the progression of this front. Prefer the slightly slower solutions of the ECMWF and GEFS ensemble mean which move this front slowly southeastward through our forecast area Thursday and Thursday night with convection along this front. Will have cooler temperatures across northeast MO on Thursday after passage of the cold front.

AVIATION. (For the 00z TAFs through 00z Friday Evening) Issued at 528 PM CST Thu Mar 4 2021
VFR conditions are expected at all local terminals through at least Friday evening. Light to occasionally breezy easterly surface winds will persist through this period, with gusts approaching 15 kt at times. Increasing mid and high level cloud cover is expected Friday morning through much of the afternoon, most noticeably at COU, but ceilings will remain VFR.
