Area Forecast Discussion . Updated Aviation National Weather Service Saint Louis MO 1040 PM CDT Mon Jun 14 2021

SHORT TERM. (Through Late Tuesday Night) Issued at 308 PM CDT Mon Jun 14 2021

An upper level ridge was centered over AZ, CO and NM with an upper level trough centered over MI and NY. A weakening, dry cold front extends from OH west through northern MO. Temperatures were quite warm this afternoon south of this front with near record highs in STL. This front will continue moving south-southwestward through the rest of our forecast area with a surface ridge over the Northern Plains building southward into our region tonight. Good radiational cooling tonight and Tuesday night with a mostly clear sky, light surface winds, and relatively low surface dew points. Lows both nights will be at or slightly below normal. Highs on Tuesday will not be as warm as today, but still around 5 degrees above normal. Went with the 25th percentile of model certainty for lows tonight and Tuesday night and the 75th percentile for highs on Tuesday due to the lack of cloud cover and the relatively low surface dew points for the middle of June. Model guidance has generally been under-performing for highs and over-performing for lows.

LONG TERM. (Wednesday through Next Monday) Issued at 308 PM CDT Mon Jun 14 2021

The dry, tranquil weather pattern will continue through at least Wednesday night. Some of the model guidance develops an MCS over IA Wednesday night in a region of low-mid level warm air advection ahead of a shortwave over-topping the upper level ridge. This MCS drops southeastward, potentially into northeast MO and west central IL Thursday morning as it weakens. For now will leave the forecast dry on Thursday as most of the deterministic and ensemble model guidance has the precipitation dissipating before making it into our forecast area. Will see warmer and more humid conditions for Thursday and Friday with surface winds becoming south- southwesterly as surface ridging shifts well east of our area. High temperatures will be around 10 degrees above normal. The chance of showers/storms will increase Friday and Friday night as an upper level trough deepens as it moves eastward from the Northern Plains into the Great Lakes region sending a cold front southward into our forecast area on Friday. This front will be the focus for scattered convection at least through Saturday as it moves only slowly southward through our area. Temperatures will trend cooler Saturday and Saturday night with the latest model guidance a little more progressive with this front.

AVIATION. (For the 06z TAFs through 06z Tuesday Night) Issued at 1037 PM CDT Mon Jun 14 2021

Largely VFR conditions are expected to prevail at all terminals through the period. There is still some concern about some valley fog across portions of central and SE MO, but today's weak cold front has dropped dewpoints in the St. Louis metro quite a bit this evening so fog at even SUS and CPS appears unlikely at this time. Otherwise mostly clear skies and light northerly winds will prevail through Tuesday.
